1. Views
of Creation and When we disagree,...
1A — Christian Views of Creation: Who, When, How
1B — Relationships between Worldviews and Science
1C — Understanding & Respect, Distortion & Conflict
( Why are so many so confident? )
1D — ASA's Views of Creation, Evolution, and Design
1A. Christian views of
creation — who, when, and how?
Most members of ASA think
that three creation views, plus variations, are compatible with Bible-based
Christianity:
In young-earth
creation, everything was miraculously created in 144 hours, less
than 10,000 years ago. Later, most of the earth's geology and fossils
were formed in a global flood.
In old-earth progressive
creation, during a long history of nature (billions of
years) God created using natural process plus miracles, with independent
creations of new species and/or creations
by modification of existing genetic material.
In old-earth evolutionary
creation (theistic evolution), God designed the universe
so everything in nature would evolve by natural process that
could be guided by God.
What about the origin of life? With young-earth creation every species (from bacteria to dogs and humans) was instantly created. Most progressive creationists think God miraculously created the first one-celled living organism, but most evolutionary creationists (or perhaps all, if when defining each type of creationist we "draw the line" as in the paragraph above) think the first life was formed by natural process.
The when-and-how of
these views are young-earth with miracles, old-earth with
miracles, and old-earth without miracles, so there are differences when we examine the many meanings of evolution. Theologically, all
three are equally creationist, even though — due to the unfortunate
abuse of a word — many
people think "creationism" refers to only young-earth views.
In addition, these monotheistic
views are challenged by those (including atheists, deists, polytheists, and
pantheists) who propose other views, and by agnostics who say "I don't know" or "we
cannot
know."
1B. What
are the relationships between science and worldviews?
As individuals and in
groups, we have a worldview — our
view of the world, used for living in the world — that includes
our views of nature and science. We want all of our ideas to be
consistent, and this leads to mutual influences between worldviews and
science, and adjustments of ideas:
• Science is influenced by
worldviews and related factors (personal desires, group pressures, cultural
thinking habits, ideologies,...) that operate in a complex social context
in individuals and in groups. { I think we should recognize these
influences, and try to minimize their effects on the process and
conclusions of science; we should challenge the extreme skepticism
of postmodern relativists when they claim that these influences
diminish the overall credibility of science and the reliability of scientific
conclusions, as in young-earth criticisms of historical
science; but we should carefully consider the
potential influence of naturalistic assumptions. }
• When we think about "the
way the world is, and why" — as when we ask, "is God actively involved in the world by guiding natural process and in other ways?" — our views are influenced by science, which
is a cultural authority because it has been very useful for understanding
nature and developing technology.
When we study origins, for
example,
An atheist or deist or rigid
agnostic has no scientific freedom, since only one conclusion — a
natural Total Evolution of Everything, without God — is
acceptable.
A Judeo-Christian theist has
options that allow "following the evidence" to any conclusion
about the when-and-how of creation. But theology, interacting with
other factors, leads some theists to demand a particular conclusion about age or evolution.
1C. Understanding and Respect? or Distortion
and Conflict?
Why are so many so confident? Because
eventually, due to adjustments among ideas, most of us become satisfied
with the quality and consistency of our own ideas. Thus, vigorous
advocates for every view of origins confidently believe they have The
Answer, and (as Del Ratzsch says) "each
side can see the case as so utterly closed that the very existence of
opponents generates near bafflement."
In high school, our civics teacher often
held debates in class about a wide range of controversial questions.
Monday he convinced us that "his side" was correct, but Tuesday
he made the other side look just as good. We soon learned that,
to get accurate understanding, we should
get the best information and arguments for all sides of an issue.
After we did this and we understood more accurately, we recognized that
people with other views may also have good reasons for their views,
so we learned respectful attitudes.
But respect does
not require agreement. We can respect someone and their views,
yet criticize their views. Our teacher was not a postmodern
relativist, and his goal was teaching us to rationally evaluate ideas.
In this educational website,
you'll find coherent overviews (for a wide range of views) and links (so
you can explore in more depth). Our goal is to help you rationally
search for truth. We want to help you avoid unintentional distortions, because
you'll understand your opponents' views. And respect — for
people and intellectual honesty — should provide motivation, for
all of us, to avoid building weak "strawmen" that are intentional
distortions of opposing views.
But even with understanding
and respect, the mere fact of disagreement can lead to conflict. The
intensity of conflict (and associated emotion) is often increased by the
importance of the issues being debated, as in applications for education.
In situations
where conflict seems worthwhile, we can disagree with respect,
in a way that is more enjoyable and is more likely to be productive. And
sometimes a better outcome can be achieved through a willingness
to look for common ground, and cooperate in a search for mutually
beneficial win-win solutions.
1D. What are ASA's views
about creation, evolution, and design?
Are we creationists? yes
and no, since it depends on how creationism is defined.
YES. All members of the American
Scientific Affiliation are Christians, so we all believe that God created everything,
using natural
process (which He designed, created, and sustains, and can guide) and/or
miracles. How did God create? We agree about the essential
doctrines of creation, but we "hold
a diversity of views [about the details of creation] with varying degrees
of intensity. (Jack Haas, former journal editor and a current website
editor)"
NO. Most of us are not "creationists" if
this means believing the earth is young, because — based on our studies
of theology and science — most members of ASA think the earth and universe
are billions of years old.
"As
an organization, the ASA does not take a position when there is honest
disagreement between Christians on an issue. We are committed
to providing an open forum where controversies can be discussed without
fear of unjust condemnation. Legitimate differences of opinion
among Christians who have studied both the Bible and science are freely
expressed within the Affiliation in a context of Christian love and
concern for truth." (preface to ASA's Statement
of Faith)
ASA does not advocate a conclusion about the "when and how" of creation,
but we endorse a process of respectful discussion, so we can learn
from each other, so we can better understand the similarities and differences
in our views of theology and science. Since 1949, ASA — in
its journal, websites, and in other ways — has provided an open
forum for a variety of views about origins. As explained in a disclaimer
for this website, "you'll find links to resource-pages
expressing a wide range of views, which don't necessarily represent the
views of the American Scientific Affiliation."
Our journal and websites are
educational resources, not declarations of policy. We in ASA won't
tell you what to conclude, but we will provide information so you can make
an informed evaluation and reach your own conclusions.
2. Using
Information from Nature and Scripture
2A — Science and religion in conflict? is
it warfare?
2B — Is comparing the Bible with science impossible?
2C — How can we wisely use the two books of God?
2A. Are science
and religion in conflict?
A common view
of the relationship between science and Christian religion — inherent
antagonism and warfare, in a conflict between the rationality of science (searching
for truth) opposed by the ignorance of religion (trying to block
progress) — is entertaining and dramatic, with heroes and villains
clearly defined. It is useful for anti-Christian rhetoric, and
has exerted a powerful influence on popular views about science and religion. But
it's oversimplistic and inaccurate, and is rejected by modern historians. For
example, David Lindberg & Ron Numbers see "a
complex and diverse interaction that defies reduction to simple ‘conflict’
or ‘harmony’... and varied with time, place, and person." {examples: Flat
Earth & Galileo}
Here are five reasons to
see conflict: wanting to believe in "science-versus-religion conflict" to support
a personal rejection of Christian faith; a failure to distinguish between scientism, which occurs when science is extended into areas where it isn't justified, and science; a
perception that "natural" means "without God" (but this
isn't a Christian view); thinking that biblical miracles and the methods of science
cannot coexist (but reliable science doesn't require always natural, just usually natural); a belief that conclusions in science cannot
be reconciled with statements in the Bible (but this is due to overly rigid interpretations of the Bible, as discussed in 2B).
2B. Can we compare science
with the Bible?
We can compare our
interpretations of nature (in science) and our interpretations
of scripture (in theology), but we cannot compare the "uninterpreted
realities" of nature (created by God) and scripture (inspired
by God). We can compare science with theology (while recognizing
that both are based on human interpretations) but we cannot directly
compare
science with scripture.
Our science and theology are based
mainly (but not totally) on interpretations of nature and scripture, respectively. In
science, the main goal is to understand physical reality. In theology,
the main goal is to understand spiritual reality. But the main goals
aren't the only goals, and our theories about spiritual and physical realities
are mutually interactive; theology affects science and our views of physical
reality, while science affects theology and our views of spiritual reality. { Some
influences — in scientism and natural theology, in scientific and theological
views of nature, natural process, and miracles — are examined in the
full-length page. }
In 1500, science and theology
were in harmony, but were wrong, when both agreed that planets orbited
a stationary earth. For awhile, as in the time of Galileo, some
interpretations of nature were in conflict with some interpretations
of scripture. In 1700, science and theology were again in harmony,
but now both interpretations were true because they corresponded
to the realities in nature and scripture.
Can we learn a lesson from history? In
the 1600s, erroneous interpretations of the Bible were used to support earth-centered
science that was wrong. Currently, are erroneous interpretations of the
Bible being used to support young-earth science that is wrong?
In 1700 we did not compare the
Bible (which says "the sun rises") with
science (which claims "the earth rotates") and decide science was
more important, because the Bible and science cannot be compared. Instead,
we compared different interpretations (of the Bible, and of nature) and wisely
used all available information in our search for truth.
When we ask, "Is this Bible
passage intended to teach us specific facts about nature?", information
from nature can be useful. This principle of theological interpretation
was recommended by the International Council
on Biblical Inerrancy (1982) when they affirmed that "in
some cases extrabiblical data have value for clarifying what Scripture teaches,
and for prompting correction of faulty interpretations."
2C. How can we wisely combine information from
nature and scripture?
God has graciously provided us
with two valuable sources of information. Of course, for the most important
things in life — for learning about God and how He wants us to live and
love — the Bible is more important. But for other questions we
don't have to make an either-or choice, and by using both sources of information
our understanding of total reality (physical plus spiritual) can be more complete
and accurate.
A good way to think
is in Psalm 19, where an appreciation of God's dual revelations
in nature ("the heavens declare the
glory of God") and scripture ("the
law of the Lord is perfect, reviving the soul,... giving joy
to the heart") inspires a personal dedication: "May
the words of my mouth and the meditation of my heart be pleasing
in your sight, O Lord, my Rock and my Redeemer."
The full-length page summarizes
useful principles for comparing different views in science (by carefully
evaluating the evidence and logic) and theology (in studies of language,
context, and consistency) and explains why "credentials and character" are
not useful for distinguishing between two views when "proponents
of both views include intelligent scholars with scientific expertise
who are devout Christians with high moral character, who sincerely want
to find the truth."
The next two FAQs look at science and theology, when we ask "How
old is the earth?"
3. What does Bible-information say
about age?
3A — Is an old-earth view of Genesis 1 satisfactory?
3B — Does the gospel require "no death before sin"?
3C — Is young-earth belief necessary for a Christian?
3D — Is it wise to link the gospel with a young earth?
3A. Is an old-earth
interpretation of Genesis 1 satisfactory?
In a young-earth 144-hour interpretation,
each "yom" is a 24-hour day. In
a day-age view, "yom" has one of its other
meanings: a period of time with unspecified length. Or maybe
creation occurred in six nonconsecutive days with long periods
between the days; or in six days of proclamation God described
what would occur during creation. A gap view
proposes an initial creation (in Genesis 1:1), catastrophe (in 1:2),
and re-creation on the earth (beginning in 1:3).
In a framework view,
the six days describe actual historical events, arranged topically instead
of chronologically. The framework is based on two problems in Genesis
1:2, with the earth being "formless and empty." The two
solutions are to produce form (by separations in Days 1-3) and fill
these forms (in Days 4-6) to connect related aspects of creation history in Days
1-and-4, 2-and-5, 3-and-6. { If you carefully study the
text, you'll see the pattern; then look at the
visual summary in the full FAQ for 3A. }
Or maybe the only purpose
of Genesis 1 was teaching theology to its original readers,
using their theories about physical reality (their ancient
near-east cosmology) to more effectively challenge
their theories about spiritual reality (their polytheistic "nature
religions").
All
interpretations should emphasize the essential creation-theology in
Genesis 1: everything was created by God, and is subordinate
to God; nature is not divine, and there are no polytheistic "nature
gods" so we should worship only the one true God. Humans
are special because God created us in His image, and our problem is
not being physical (since God said his physical creation was "very
good" for achieving His purposes), our problem is sin.
The two main arguments for young-earth theology are the claims (above)
that Genesis 1 teaches a 144-hour creation, and (below) that "animal
death before human sin" is theologically unacceptable.
3B. Does the gospel
(and salvation) require "no death before sin"?
John
Morris says, "In this view, death is not the penalty for sin, for it preceded man and his sin. ... If the earth is old, if fossils
date from before man's sin, then Christianity is wrong! These ideas
destroy the foundation for the Gospel and negate the work of Christ on
the cross. (source)" Ken Ham agrees: "As
soon as Christians allow for death, suffering, and disease before sin,...
the whole message of the Gospel falls apart. ... If there were death, disease, and suffering before Adam rebelled — then what did sin do to the world? (source)"
These
claims appeal to our emotions — because we want a world where
only good things happen, with no suffering or death — and offer a simple
answer for a difficult theological question: if God is all-good and
all-powerful, why does God let bad things happen? When you first
see it, a young-earth theology of "no animal death before human sin" may
seem
strong,
but this claim becomes much weaker when
it's examined more carefully. Morris and Ham ask a question — if the earth is old and "death is not the penalty for sin, for it preceded man and his sin... then what did sin do to the world?" — that is clearly answered in Genesis 3:22 when God establishes a death penalty for humans; because Adam has sinned, "he must not be allowed... to live
forever" so God prevents this by temporarily removing "the tree of life" that would have sustained him (and Eve, and us) with eternal life.
A Brief History of Sin
and Salvation
The Bible says very little
about animal death. Instead, the focus is on our problem (human
sin leading to human death) and God's solution — for converting
sin and death into salvation and life — that works whether the earth
is young or old.
God offered the gift of full life
(with relationship, quality, and immortality) to Adam but — following the
lead of Eve, who was tempted by a creature that already had rebelled against
God
— he rejected it by his sinful disobedience when he chose to make moral decisions
independent
from
God, instead of trusting and obeying God. This fall into sin, which broke Adam's part of a conditional if-then covenant with God, produced
three results in Genesis
3:7-24 including spiritual death (intrinsic penalty in 3:7-13) and physical death (judicial penalty in 3:22,24): their decrease in relationship with God, decrease in quality of life,
and loss of everlasting life: "The man has now
become like one of us, knowing good and evil. He must not be allowed
to reach out his hand and take also from the tree of life and eat, and live
forever." When the full supernatural protection provided
by God (symbolized by the "tree of life")
was removed by God, Adam and Eve began to perish, with natural processes
temporarily allowing life while gradually (during the "yom" of Genesis
2:17 that, as in Genesis 1, can indicate an indefinite period of time instead
of a 24-hour day) leading
to their death.
We had sinned and thus earned
death. We needed a savior, and God is merciful, so the gift of life (with
relationship, quality, and immortality) was won back for us by our savior. Jesus
Christ accepted the penalty of death that each of us earns (by our sinful disobedience)
and He (by living in sinless obedience to the Father) earned the right to make
His own Eternal Life available, as a gift of grace, to all humans who will
accept: "The wages of sin is death, but the gift
of God is eternal life in Christ Jesus our Lord. (Romans 6:23)" The
gift of full life — both spiritual and physical — that in Genesis was temporarily taken from us (because of sin)
will be permanently given back to us (because of Jesus) in Revelation. (Rev
2:7 & 22:1-2,14) In
heaven there will be no sin and no death, and God's goals for us will be permanently
actualized. Amen.
3C. Is young-earth belief
necessary for a Christian?
Some Christians claim
that belief in young-earth creation is necessary for correct Christian doctrine, although
it isn't necessary for salvation.
How can we decide if a
doctrine is essential? We can look at its certainty and importance by
asking, "Is it taught with certainty in the Bible, and is it theologically
important?"
For example, consider the
claim that after Jesus died he was brought back to life.
Yes, this is taught with certainty,
beyond any reasonable doubt, as in the first Christian sermon by Peter in
Acts 2:14-36.
Yes, this is important for Christian
theology. Paul says, in 1 Corinthians 15:14, that "if
Christ has not been raised, our preaching is useless and so is your faith."
This claim is certain and
important, so it is an essential doctrine, a core-belief of Christianity.
Is a young earth essential?
Is it certain? After
carefully studying Genesis 1 and the whole
Bible, most evangelical Christian scholars have decided that an old-earth
view is justifiable, maybe preferable, or that neither view is clearly
taught, so believing the Bible is true does not require believing a
young earth, and humility is appropriate. For example, in 1982
the International Council on Biblical Inerrancy decided (by
agreement of all members except Henry Morris) to not include 144-hour
creation as an essential part of a belief in inerrancy.
Is it important? Section
3B examines a central young-earth claim — that if the earth is
old, with animal death before human sin, this will "negate
the work of Christ on the cross" — and
explains God's plan for salvation that works whether the earth is young or
old. Other essential Christian doctrines are also age-independent, so the
full gospel of Jesus — including His deity, virgin birth, teaching
and miracles, sinless obedience to the Father in life, substitutionary atonement
in death, victorious resurrection, ascension into heaven, and second coming — is
fully compatible with a young earth or old earth.
Let's look at three young-earth
claims by Ken Ham:
• He thinks it is wrong to "start
outside the Bible to (re)interpret the Words of Scripture." But
he does "start outside the Bible" when
he rejects a claim that the Bible teaches a stationary
earth. He accepts evidence from nature (logically interpreted
in science) and uses it as a motivation to reconsider scripture, and when
he looks carefully he finds valid reasons to accept a moving-earth interpretation
of scripture. In a similar way, many Christians find valid reasons
to accept an old-earth interpretation of scripture.
• He criticizes "man's
fallible dating methods" and asks, "Can
fallible, sinful man be in authority over the Word of God?" Is
Ham claiming that an old-earth interpretation of nature is hindered
by sin, but his own young-earth interpretation of scripture is
not hindered by sin, so his interpretation of the Bible (not
just the Bible itself) is infallible? And his claim about "authority" ignores
the fact that we cannot compare the Bible with science, we
can only compare interpretations of the Bible (in theology) with interpretations
of nature (in science) while trying to search for truth.
• He thinks rejecting a young-earth
will lead to rejecting essential doctrines, "even
to Christ's Resurrection," in a "slippery
slope to unbelief." But do all claims that "the Bible
teaches this" have equal support? No. We can rationally
decide that a 144-hour creation is not true, but The Resurrection is true
and is an essential doctrine because (compared with a young earth) it is
much more certainly taught and is much more important.
These
claims are also made by geocentrists in
the Association
for Biblical Astronomy who think the earth is stationary and the
sun (along with everything else in the universe) revolves around the
earth. Why do they believe this is true? Because they "assume
that whenever the two [Bible and conventional astronomy] are at variance,
it is
always
astronomy — that is, our "reading" of the ‘Book of
Nature,’ not our reading of the Holy Bible — that is wrong." Does
this sound familiar?
So why does Ham think that he, as a fallible sinful
man, can avoid a "slippery
slope" by rationally deciding to interpret the Bible in a non-literal
way for a stationary
earth but not a young earth? Why
is Ken Ham not a geocentrist?
3D. Is it wise to link The Gospel with a young
earth?
Most evangelical scholars
think a young earth is not an essential doctrine. And most scientists,
including Christians, think a young earth is almost certainly false,
based on their logical evaluations of evidence from nature.
Despite these reasons for
caution, John Morris boldly declares that "if
the earth is old... then Christianity is wrong!" and Ken
Ham agrees that "the whole message of the
Gospel falls apart." Is this wise? What are some
results of young-earth claims?
A claim that "if the Bible
is true, the earth is young" is logically equivalent to saying "if
the earth is not young, the Bible is not true." What happens when
a person who thinks "the Bible requires a young earth" examines the
scientific evidence and concludes "the universe and earth are old"? Another
conclusion may be that "if the Bible is wrong about the earth's age, maybe
it's also wrong about the rest," so the Bible's authority is weakened,
and faith is weakened or abandoned. This is a real dilemma for many of
our brothers and sisters in Christ, so we should help them and pray that they
emerge from the experience with renewed faith in the Bible and faith in God. Another
problem is that non-Christians who are earnest seekers of spiritual truth — and
who think a young earth and Jesus are a "package deal" that includes
both or neither — may reject the whole package because, based on their
knowledge of science, they think the earth is not young.
Therefore, it seems wise for
Christians to not encourage (and not accept) any implication — whether
it comes from fellow Christians who want to strengthen the Gospel, or non-Christians
who want to discredit the Gospel — that "if the earth is not
young, the Bible is not true."
Appropriate Humility
Proponents of a young earth
should be admired for their desire to determine what The Word of
God teaches, and believe it. But I wish they would
humbly consider the possibility that their interpretation of
the Bible is wrong, and would adopt
a more loving attitude toward their brothers and sisters in Christ
who have other views of when-and-how God created so they don't include
young-earth belief as part of their Christian faith.
Instead, there is a "not
in our church" attitude, as when John Morris says: "Old-earth
thinking is incompatible with the work of Christ. ... [young-earth] creationism
should be a requirement for Christian leadership! No church should
sanction a pastor, Sunday school teacher, deacon, elder, or Bible-study
leader who knowledgeably and purposefully errs on this crucial doctrine. (source)"
I agree with Morris that,
for essential doctrines, we should not be "tolerant" as defined
in postmodern relativism. We should say "this is what the
Bible clearly teaches, and it is important." But for nonessential
doctrines, we should be more appropriately humble. It seems wise,
for personal faith and interpersonal evangelism, to focus on doctrines
that are most clearly taught and most important, and when all things
are considered (including information from nature) seem most likely to
be true.
Some words of wisdom, useful in
all areas of life, come from St. Augustine: "In
essentials, unity. In nonessentials, diversity. And in all things,
charity." To follow this advice, we must wisely distinguish between
what is essential and nonessential, and behave with charity, with respectful
humility and a love that transcends our differences, so "everyone
will recognize that you are my disciples, when they see the love you have for
each other. (John 13:35)"
4.
What does information from nature say about age?
4A — Is there evidence for an old earth-and-universe?
4B — Can historical science be scientific and reliable?
4C — Did God create a young universe that looks old?
4A. Do we have evidence
for an old earth-and-universe?
The explanations proposed
in young-earth flood geology seem incorrect (because they
don't match what we observe) for geology and for the spatial arrangement
of fossils within this geology. By contrast, old-earth theories
of modern geology — which propose a combination of slow-acting uniformitarian
processes and fast-acting catastrophic events (such as
volcanoes and floods) — produce explanations that match observations.
Evidence from a wide range
of fields — including the study of sedimentary rocks, coral reefs,
the fossil record in geological context, biogeographical patterns in
fossils, seafloor spreading and continental drift, magnetic reversals,
genetic molecular clocks, radioactive dating, the development of stars,
starlight from faraway galaxies, and more — indicates that the
earth and universe are billions of years old. If the universe
is young, all of these fields are wrong, and we must discard much of
modern science. This isn't likely to happen, nor does it seem
desirable.
The reasoning is not circular,
because "a long time" is a necessary component of many theories that
in most other ways (such as the domains they explain and the components
they include) are independent. This logical principle of multiple
independent confirmations has convinced almost all scientists
that the earth and universe are very old, and that evidence from nature
provides strong logical support for this conclusion.
Proponents of young-earth
views can respond in four ways: A) claim their own logical analysis
of the evidence is better than the conventional analysis so the logic of science should lead to young-universe conclusions; you can examine
the evidence-and-logic in pages by me and other scientists (both old-earth and young-earth); B)
acknowledge the weakness in current young-universe science, but hope
it will improve in the future; C) challenge the credibility of
historical sciences; D) claim the universe is young even though
it looks old. The last two responses, C and D, are examined in the next two
sections.
4B. Can historical science
be "scientific" and reliable?
We cannot observe events
in ancient history. But can we — by a logical analysis
of historical evidence, in sciences like archaeology, geology, radiometric
dating, and astronomy — reach reliable conclusions about what
happened in the past?
Proponents of a young earth are
skeptical. They ask "Were you there? Did you see it?", and
imply that "no" means "then you can't know much about it." They
are trying to "discredit the old-earth witness" that (as summarized
above in 4A) is testifying against their views. Is the witness
reliable?
The logical methods are
similar in two "modes of science," in operations
science (to study the current operation of nature, what is happening
now) and historical science (to study the
history of nature, what happened in the past). Usually, theories
in historical science are based on, and are thus consistent with, theories
in operations science.
In either mode, scientists
can logically infer an unobservable cause that produces observable
effects. For example, scientists propose electrons (in chemistry)
and ideas (in psychology) because what we can observe is best explained
by theories proposing the existence of electrons and ideas we cannot
observe. Similarly, we can infer the existence of historical
events if these unobservable events produced evidence we can observe
now.
The main difference between modes
is that historical sciences use data from uncontrolled field experiments, not controlled
lab experiments. Sometimes the limitations of historical data provide
a reason for caution about conclusions. But scientists have developed
strategies to reduce the practical impact of data limitations. For
example, repeated observations of many Cepheid-stars from many parts of the
universe have shown that all Cepheids have similar properties, which lets
us measure the distance to faraway Cepheids, and calculate that it takes
billions of years for their light to reach us.
Extreme relativists — including
postmodern skeptics who challenge all science, and creationists when
they challenge historical science — claim that in science the evidence
is inadequate, so conclusions are determined by nonscientific beliefs. But
most scholars, including myself and other members of ASA, think extreme
relativists are exaggerating the logical difficulties, and historical
sciences — which are based on a logical evaluation of empirical
evidence — provide a reliable way to learn about the fascinating
world created by God.
4C. Did God create a young universe
that looks old?
The evidence for an old
universe is impressive, but can we believe what we see?
It takes billions of years
for light to travel from distant stars to the earth. How can we
see this light, if the universe is less than 10,000 years old?
Most proponents of a young universe
claim that God created the universe with appearance
of age as a mature creation that would
be immediately functional, with mature humans (not helpless infants), balanced
ecosystems, our energy-giving sun, and starlight created "in transit to us" instead
of coming from a shining star. This beginning of history is analogous
to a movie that begins in the middle of an action scene, without showing
everything leading up to the action. The universe appears to be older
than it actually is, so it has a false apparent age (AA).
Yes, if the earth is young, some
AA would be essential for Adam and Eve in Eden. But some AA doesn't seem
necessary, so we can ask: Would an honest God create a universe with detailed
nonessential evidence for events that never occurred? For example,
in 1987 scientists observed starlight from 170,000 light-years away, with characteristics
changing in a way that corresponds to the sequence of events during a supernova
explosion. Should scientists conclude that this supernova-event really
did occur, or that it's part of an apparent history (created
by God) about events that "would have happened in an old universe" but
never really happened?
Young-universe creationists can
propose apparent histories that are minimal (with only essential-AA),
or total (with all details about an old universe), or partial. With
minimal-AA, most evidence was produced by actual history, so most old-universe
conclusions of science must be challenged. By contrast, with total-AA
and perfect "antiquing" it would be impossible to scientifically distinguish
between a universe that actually is billions of years old and a universe
created 6000 years ago (or 5 minutes ago) that just appears to be old. But
usually AA (proposing some false observed age) is combined with flood geology
(proposing a true observed age for all features produced in a global flood); a
hybrid theory of "AA plus flood geology" can be tested, as discussed
in 4A.
In my opinion, theories proposing apparent
age are worthy of careful, respectful consideration, but there are
theological reasons to prefer a theory of actual age (proposing
that the world actually is the age it appears to be) with God creating
a universe that "began
from the beginning" so
what we see is the actual history of what really happened. {other
opinions are in APPEARANCE OF AGE:
THEOLOGICAL QUESTIONS}
5. What can a Christian believe about evolution?
5A — Does "natural" mean "it happened without God"?
5B — a universe "just right for life" — Is it designed?
5C — Can we prove the existence and activity of God?
5D — Is nature designed for 100% natural assembly?
5E — Is "theistic evolution" an impossible combination?
5F — Should we eliminate "God of the gaps" criticism?
(and avoid two
either-or choices)
5G — What is an appropriate humility about creation?
5A. Does "natural" mean "it
happened without God"?
No, because — in
a Judeo-Christian
worldview — God designed and created natural process, and continually sustains
its operation. And natural does not mean "without control" because
God can guide natural process to produce a desired natural-appearing result instead of
another natural-appearing result.
A theistic view of natural process
helps us appreciate science, which helps us understand
how
God
designed
nature.* More important, it allows a better perspective on everyday life. Christians
believe that God is caring for us, that He can change our situations, guide our
thoughts and actions, and He responds to prayer. Usually all of this happens
in normal ways that appear natural, yet God is actively involved. We
should pray for these natural-appearing divine actions and praise God for them, as we "live
by faith" when we trust God in daily living.
5B. Three Explanations
for a "just right" Universe
An amazing discovery of scientists,
in recent
decades,
is that many properties of the universe are "just
right" for life. For example, we have sunshine due to a tug-of-war
lasting billions of years, with some forces pulling the sun's fiery atmosphere
inward,
while other forces push it outward, but neither can "win" due to a
fine-tuned balance of forces. To understand the fine
tuning that allows sunshine and many other wonderful features of our world,
imagine
that
you
are
sitting
in
front
of
a
control
panel
with
dozens of dials. To allow life, each dial — which controls one property
of the universe — must be tuned to a specific setting within a narrow range. You
are alive because all dials are properly tuned, and this produces a wide
variety of life-permitting natural phenomena that include stars (which produce
the energy and atoms needed for life), the chemistry of DNA, water, and proteins.
Most scientists are convinced that
fine tuning is necessary for a life-allowing universe. But there are two
main theories, and three explanations, for why our universe is what it is:
TWO THEORIES
Intelligent Design: Maybe
our universe was designed and created
by an extremely intelligent and powerful designer/creator who wanted
to make a world with sunshine, proteins, and people. A Judeo-Christian
theist will think God is the designer.
Multiverse: If there was no intelligent design, a life-supporting universe seems extremely improbable. But
in a multiverse (containing an immense number
of universes) with properties varying throughout the entire range of possibilities,
the odds would favor having at least one universe with intelligent life,
because "everything will happen" if there are enough universes.
THREE EXPLANATIONS
According to Robin Collins, "even
if a ‘many-universes generator’ exists it seems to need to be well
designed" in order to produce a multitude of universes with widely
varying properties.
A 2x2 combination of "designed or non-designed" with "universe or multiverse" produces 4 options. If we eliminate non-designed universe from serious consideration, due to its extreme improbability, there are 3 options.
Therefore, the choice is not
either design OR multiverse,
but instead is
either designed
universe or designed multiverse OR non-designed
multiverse.
NO CONCLUSION?
According to the most common multiverse theories
(based on string theory and hyperinflationary expansions) other universes are
in a different space-time framework, or are very far away, so they cannot be
observed. Therefore, the fact that we don't observe other universes does
not count as evidence against a multiverse theory. But we haven't
observed any other universes, so there is no direct evidence for them. The
scientific implications would also be inconclusive if scientists discover a "grand
unified theory" showing relationships among the properties of nature in
our universe.
Two types of aesthetic objections don't provide reasons that are valid (logically, philosophically, or theologically) to reject a multiverse theory, as explained in The Anthropic Principle - Multiverse and/or Intelligent Design. One objection — saying "in a multiverse everything would happen and that would be strange," which basically says "I don't like it" — is not logically warranted. Second, a preference for elegant simplicity in a theory (as stated in Occam's Razor) should not be used to criticize a Multiverse Theory proposing zillions of universes, for the same reason we don't criticize Atomic Theory because it proposes a million billion billion atoms in a cup of water.
Or maybe we should just say "so
what?" because if we are observing a universe, obviously it must have
properties that allow our existence. This Anthropic
Principle — which states that because humans exist, the universe
we observe will be consistent with our existence — is
logically valid, and is compatible with either
the presence or absence of a designer, so it doesn't favor any explanation. This Anthropic Selection Principle, which restricts the type of universe-properties we are able to observe, can also be used to "beat the odds" in sciences studying life (including its origin) and thus neutralize any claim for intelligent design that is necessary for producing intelligent observers.
How did our universe begin, and why does it have
properties that allow life? All three explanations (designed universe, designed multiverse, non-designed multiverse) seem impossible to prove
or disprove, mainly because our evaluations are hindered by an absence of evidence
about what existed (and what happened) before the Big Bang Beginning. An
atheist assumes the existence of a materialistic capability
for creating our universe. A theist assumes the existence of God, who
has this capability. Each asks the other, "Can you explain what caused
the existence of what you assume as the starting point?" Neither offers
an answer that satisfies the other, and neither assumption can be proved. Hence,
no conclusion?
faith and praise: Christians
believe that God designed and created our world, even though we cannot
prove it. We praise God for the sunshine that warms our bodies,
grows our food, and lets us see. And when scientists learn how
sunshine is produced by natural process, we should praise God for his
wonderful design of nature! (whether he designed nature by using a universe or multiverse)
5C. Can we prove the existence
and activity of God?
Some debaters try to
logically prove or disprove the existence of God. But proof seems
impossible, and this is frustrating for those who seek certainty.
The Bible claims that God
can do miracles. So why doesn't God do persuasive miracles more
often? And why didn't the risen Jesus go to downtown Jerusalem
and show everyone that He was alive? And why doesn't God give everyone
a compelling "Damascus Road experience" as with Paul in Acts
9?
And if God wants us to recognize
Him as Creator, why is there evidence — like a gradual increase
of biocomplexity and biodiversity, an appearance of common descent, and
long delays between biological innovations — that leads some rational
people to propose "atheistic evolution" as an explanation? And
why, as discussed above, is the explanation for fine tuning also ambiguous?
Perhaps the universe was
cleverly designed so all creation would occur by natural process.
Or maybe "creation miracles" would
be more widely accepted if scientists were free from the restriction of methodological
naturalism.
Or maybe there is intentional
ambiguity — either because creation miracles were not needed, or
did occur but were "veiled" so they're not easily detected by scientists — because,
in this way and in other ways, God wants to preserve a state of uncertainty
(about His existence and activities) with enough logical reasons to either
believe or disbelieve, so each of us is free to make a personal heart-and-will
decision without being overwhelmed by external evidence.
Absolute truth does exist,
even though we cannot know with absolute certainty what this truth is. Each
person can estimate the plausibility of various worldviews by using evidence
that is historical (as in the Bible), personal (with God
giving us individually customized experiences, and drawing us to himself
through his Holy Spirit), interpersonal (by talking with others,
or reading what they write, to share in their experiences and thinking), scriptural (by
studying the Bible), and scientific (by studying nature). But
there is no logical proof for any worldview.
We thus have freedom to
choose what we want to believe, which is influenced by how
we want to live, and the lack of certainty forces each of us — no
matter what we believe in our unique personal worldview — to
live by faith in what we believe. Those placing their faith in
Christ have an opportunity to develop the "living by faith" character
that is highly valued by God, with a trust in God serving as the foundation
for all thoughts and actions in daily living.
Worldview Asymmetry: At least one miracle
in salvation history — in the resurrection of Jesus — is
essential for Christian belief, but "no miracles in formative history" (or
in current
daily life) is fine for a Christian. By contrast, undeniable evidence for
any divine miracle, during either formative history or salvation history, would
be devastating for the worldview-faith of an atheist,
deist, or rigid agnostic.
Questions about "evidence and uncertainty" are examined more
thoroughly, along with ideas from C.S. Lewis and speculations about Life
as Drama, in a page asking Why
isn't God more obvious?
5D. Did God design nature
to be 100% naturally-assembling?
Science tells us that many properties of nature
are "just right" to let nature be at least partially natural-assembling. But when we ask whether nature was totally natural-assembling, including a natural origin of life, the most logically justifiable answer from current science is that "we're not sure." Thus, for an important question — During the formative history of nature, was the degree of natural assembly 100%, or was it 99.99...% with God “doing what was necessary” when natural process wasn't sufficient? — we don't have a certain answer.
Is 100%-natural assembly
possible? Maybe not. Maybe there is a tension between operation and assembly, so
if God wants a universe with optimal operation it cannot also
be totally assembling. To illustrate, Walter Bradley asks if a car designed to change its own spark plugs would be a good design, or if this unnecessary feature would hinder the car in other ways that are more important. Maybe it's possible for nature to have both optimal operation and total natural assembly. But maybe it isn't possible.
When we consider the current state of science and a possible tension between operation and assembly, it seems wise for evolutionary creationists to be humble. They should not demand an unquestionable conclusion, by all Christians, that the history of nature was totally natural. But this un-humble demand occurs when they scornfully say "that's just a God of the gaps claim" in response to any questioning of 100% natural assembly.
If the universe was cleverly
designed so it could totally assemble by natural process, this would
be impressive. But miracles are also impressive, and they
eliminate the need for total natural assembly. Either way, God can enjoy interacting with his creation — by only guiding natural process (if natural assembly is 100%) or (if natural assembly is less than 100%) by natural guiding plus miracles — like a gardener caring for his
fruitful garden. Either method of creation, with or without miracles, is worthy of God, and every Christian who is appropriately humble (who would not confront God and say "you did it wrong") should acknowledge this.
In our search for truth, we
are influenced by a variety of internal and external factors that produce a wide range of personal preferences. Some people prefer a total natural assembly, while
others want miracles during the creation process, and — even when the most scientifically justifiable conclusion is that "we're not sure" — these two personal preferences can lead to strong opinions about the methods of creation used by God. Neither preference
is clearly taught in the Bible, but both seem compatible with what is clearly
taught.
Appropriate Humility (not too little, not too much) is a central theme of Sections 5A-5G, and here is a perceptive observation from Bertrand Russell: "Error is not only the absolute error of believing what is false, but also the quantitative error of believing more or less strongly than is warranted by the degree of credibility properly attaching to the proposition believed, in relation to the believer’s knowledge."
5E. Is "theistic
evolution" an
impossible combination?
Is evolution inherently atheistic,
or can it be part of a Christian worldview? Some atheists and Christians
criticize theistic evolution in a two-step argument: First, they accept
the atheistic claim that natural process happens without God. Second, this
bad theology is used to claim that "natural evolution is atheistic, so theistic
evolution is impossible."
This argument is theologically
flawed, since it accepts an atheistic premise. It is also illogical: Even
though an atheist (or deist) must accept evolution, this doesn't justify guilt
by association with an implication that "atheists are evolutionists, so
evolutionists are atheists," for the same logical reason that "all dogs
are animals, so all animals are dogs" is false.
A person who accepts scientific theories
of evolution can have theology that is strong or weak, ranging from devout Christianity
through minimal theism and deism to atheism.
The Bible clearly states that God
sometimes does miracles, so all Christians should be open to the possibility
of miracles in any part of history. But a devout Christian who believes "miracles
occurred in the salvation history of humans (as
recorded in the Bible and continuing to the present and future)" could, after carefully thinking about theology
and science, conclude that "the formative
history of nature was all-natural." / And we can think about a total history that combines formative history (from the first instant to the present, with the past & present studied in historical science & operation science) and human history (from the first humans to the present).
But what if the main objection is about age rather
than all-natural evolution? Young-earth creationists claim that all old-earth views
(including both evolutionary creation without miracles, and progressive
creation with miracles) are "evolution" and are theologically unacceptable, mainly because
they
think Genesis 1 teaches a 144-hour creation, and animal death could
not occur before human sin, as discussed in Section
3.
A scientific/theological
theory of evolutionary creation (also called theistic
evolution *) proposes that God designed nature so complex physical
structures (galaxies, stars, planets) and biological organisms (bacteria,
fish, dinosaurs, humans) would naturally evolve, so He could create using
natural process. Is it wise and humble to claim that God could
not, or would not, or did not do this? In
our current state of knowledge about science and theology, humility seems
appropriate,
with "maybe" as the most justifiable answers.
* A linguistic reason to prefer evolutionary creation is because creation is the noun that is the main focus, and evolutionary just describes the type of creationist view. By contrast, in theistic evolution the noun-focus is on evolution, and theistic is just an adjective describing the type of evolutionary view.
If natural process was materially
sufficient to produce physical and biological complexity,
would it be theologically sufficient to
achieve the goals of God?
When thinking about this question, we should ask: 1) How
precise were the goals of God? Did he want to create exactly what
occurred in nature's history, or would something slightly different,
or very different, have been satisfactory? 2) How variable
is unguided evolution? What would happen if evolution "ran
without guidance" a thousand times?
Even if unguided
evolutionary history would be less variable than most scientists
think, some divine guiding of natural process seems necessary for God to achieve his goals in creating humans with the characteristics (physical, mental, emotional,
ethical, spiritual) and environment (planetary, ecological,...)
that he wanted for us.
I.O.U. — Later,
this paragraph will
explain
how
a divine creation of humans by a process that includes pre-human hominids can be
compatible with what the Bible teaches about humans and our
relationship
with God. {now, HUMAN ORIGINS: SCIENCE
& THEOLOGY includes four scenarios
for
Adam
& Eve}
A nontheistic interpretation
of neo-Darwinian science will see the process of evolution as being not designed
by God, using matter not created by God, driven by only chance and selection
that were not guided by God. { Was
evolution unsupervised? } But these claims are
theological, not scientific, and a theistic interpretation of the same science can
disagree by viewing the evolutionary process as being designed by God,
using matter created by God, and (at least sometimes) guided by God.
{ Divine Guiding of Natural Process }
In most fields of science
— ranging from the physics of rain to the biochemistry of embryology and physiology
— there are no theological criticisms of scientists who accept
naturalistic theories proposing "only
natural process." A proposal for theistic evolution just extends this acceptance
into other areas of science.
A deistic (or minimally
theistic) view of evolution proposes that God set nature in motion
and "let it run" by using only the foundational
divine action (with initial action
determining the characteristics of nature, and sustaining
action letting nature continue) that allows history.
A more robust actively theistic view proposes that God also used
active divine action (in natural-appearing
guidance) that makes a difference in formative history,
but not miraculous-appearing action because
God designed nature so this would not be necessary during formative history. / Or an evolutionary creationist can propose that God used only foundational divine action, with no guiding of nature during formative history (as in deistic evolution), but (unlike deism) during salvation history God also uses active divine action, both natural-appearing and miraculous-appearing.
Of course, any non-deistic claim for active divine action that "makes
a difference" — whether the action is natural-appearing or miraculous-appearing, in formative history or salvation history, as perceived in evolutionary creation or other views of creation — leads
to important theological questions: Can God (or does God) control
everything? (i.e., do any unguided events occur?) If God
is active in nature (or if he could act but does not), is He therefore
responsible for animal deaths and
harmful evolved organisms (deadly viruses,...) and "bad
designs" and various tragic events (genetic defects, hurricanes,...) that
occur in the history of nature and in everyday life?
These are difficult questions,
but one part of a satisfactory answer is the incarnation of Jesus, when
God lived among us, shared our joys and sorrows, and (on the cross) suffered
the consequences of moral and natural evil.
5F. Should we eliminate "God
of the gaps" criticism?
When current naturalistic
theories (about some aspect of formative history) seem implausible, is this science
gap caused only by the inadequacy of current scientific knowledge, or does it indicate a nature
gap (a break in the natural chain of cause-and-effect) that
was bridged by miraculous-appearing divine action?
Sometimes a claim for a
nature gap is ridiculed by calling it a "God of the gaps" theory. This
is confusing because God of the gaps can
have many meanings. It might be:
• criticizing
a claim that "God acts only in gaps" (which occurs if "natural" means "without
God" which is bad theology so it should be harshly criticized) but usually this is not being claimed when a nature gap is proposed.
• criticizing
a claim that "a
nature-gap is possible and we should consider this possibility" — and by doing this they are making a bold counter-claim that "a
nature-gap is impossible" because it was not necessary (in a claim to know with CERTAINTY that the universe is 100% self-assembling, thus rejecting the reasons for caution outlined in Section 5D), or because God would not do
• A critic who thinks "claiming a nature gap is unscientific" is
proposing methodological
naturalism.
• If a critic
rejects a specific claim that "in this historical
situation a gap did occur" and instead claims that "a gap did not
occur" we can have a respectful discussion about
the scientific and theological merits of these two
claims. This
discussion should include a process of logical evaluation (using
scientific methods in an attempt to detect design-action) in which theists should avoid
the extremes of concluding automatically — independent of
evidence — that "a science-gap must always be a nature-gap" (thus ignoring some of the possibilities) or "a
science-gap
could never be a nature-gap." / Sometimes a claim that "miraculous-appearing
action bridged a nature-gap" is criticized as an argument
from ignorance. But if this principle is generalized to all of life,
it would be impossible to recognize a miracle in any situation, which is unbiblical
because people in the Bible did recognize a miracle when they observed an
exception to the way God usually works in nature. / Critics often express a "boy who cried wolf" concern: if a claim for God's action turns out to be wrong, this could make Christians look foolish and damage our credibility. But even if some previous claims have been wrong, each current claim for a nature gap — such as the origin of life where almost all scientists agree that "the jury is still out" — should be evaluated based on its
own merit. / And a claim for a nature-gap is not a science stopper.
Many meanings are possible when someone
says "God
of the gaps" so we should ask "What do you mean?" But
to improve the precision in our thinking and communicating, I think we
should eliminate this term (which has many meanings) and
replace it with a series of terms where each term has a precise-and-clear meaning.
Christians should not demand
a choice between natural and miraculous, because God can work both ways; in the Bible, during salvation history the actions of God are usually natural
and occasionally miraculous. Affirming one mode of divine action
does not require rejecting the other:
• We should not imply (or
allow an implication) that "if it isn't a miracle then God didn't do
it," that "natural means without God" so it "counts against God
"in our worldview-thinking about divine action.
• We should
not imply that if someone claims God can (or did or does) work
through miracles, in formative history or salvation history,
they are denying God's activities in natural-appearing situations.
Both of these either-or
dichotomies are useful for atheists, in a clever "heads we win,
tails you lose" argument — if there are no nature gaps
then it all happens without God, but it's wrong to claim a nature
gap — that uses the either-or claims made by some opponents and proponents of
evolutionary creation, respectively. Christians should respond
by rejecting both arguments, heads and tails.
Instead of an either-or choice, we believe that God
can work in more than one way, so we have
our own "heads or tails" argument: when
something happens by natural process, it happens due to God's clever
design of nature; but if occasionally there is a divine bridging of
a nature-gap, this happens because God is powerful and is able to do miracles. Both methods of creation give us reasons to praise God.
5G. What is an appropriate
humility about creation?
In science and theology, our humility should
be appropriate — not too little, not too much. We can make
some claims, but not others, with confidence. Other parts of
this page look at appropriate humility for age-questions and design-questions in
science, and claims about not old-earth and not
evolution in theology.
In my opinion:
When we ask questions about age, theological arguments — claiming
biblical support for either an old earth or young earth — are
weak, but scientific evidence for
an old earth (and old universe) is extremely strong. Therefore, an old-earth
conclusion seems justified.
But when we ask, "Can natural process lead to a total
assembly of the universe?", scientific and theological arguments — claiming
support either for 100% natural evolution or against it — are not decisive,
especially when we think carefully about our definitions for divine design (in 6A)
and evolution
(in
7A). The
Bible clearly states that God used miracles in salvation history, but is less
clear about miracles in formative history, so each view — proposing a formative
history either with or without miracles, with two modes of divine action or only
one — is compatible with what the Bible clearly teaches. Therefore,
instead of criticizing either possibility as being a less worthy way for God
to create, it seems wise to be humble by deciding that, either way, God's plan
for design-and-creation was wonderful and is worthy of our praise.
You and I should say in public — and believe in our
hearts and minds — that "IF God created using another method (differing
from the way I think He created, regarding either age or evolution), then God
is worthy of our praise." But this humility (if... then...) is compatible
with humbly explaining, using arguments from theology and science, why we think
a particular view is most likely to be true.
Even when Christians disagree about the when-and-how
details of creation, we are brothers and sisters in Christ, and we can
join together
in our praise of the creator (and his intelligence, power, and wisdom)
by joyously proclaiming that "you are worthy, our
Lord and God, to receive glory and honor and power, for you created all
things, and by your will they were created and have their being. (Revelation
4:11)"
6. Was
nature designed? What is design? Who proposes
it?
6A — What are the four types of intelligent design?
6B — Is ID creationism? Who is in the Big Tent of ID?
6A. What are the four types of intelligent design?
Maybe a feature (a star, bacteria, whale, biochemical
system, radio signal, house, car,...) was produced by intelligent design,
by:
• natural process because,
before history began, the universe was designed so this would happen,
or
• natural process that
was supernaturally guided in a natural-appearing way to produce
a desired natural-appearing result, or
detectable design-directed
action by a supernatural agent (•) or natural
agent (•) rather than undirected natural process;
or maybe there was
no design, and the feature was produced by natural process that
was
not designed, not undetectably-guided, and not detectably-directed.
We should always remember the 4 definitions of intelligent
design (•••• above) and 5 definitions of evolution (•••• • in Section
7A) when we're thinking about these complex topics.
Can we detect design by using the methods of science? This question requires four answers, one for each type of design defined above: In my opinion, the answers are NO (as explained in Section 5B although future science may change this), NO (by the definition of natural-appearing), MAYBE and YES (as explained in Section 7B).
note: In the rest of this page, design means detectable
design-directed action, unless another meaning is clarified. For most other authors this is also
the usual definition,
but it's
not
the
only
definition so you should try to understand the author's intended meaning by looking at the context. Unfortunately,
confusion often occurs due to miscommunication between writers — when
they don't clarify their intended meaning, or intentionally ignore differences
in
meaning, or don't even understand the differences — and readers.
6B. Who is in the Big
Tent of Intelligent Design, and why?
An atheist rejects divine design and will
affirm only design-action by a natural agent.
All theists should
accept the possibility of
all four types of design. But there is disagreement about the reality of
detectable design-action; evolutionary
creationists think this was not necessary in formative history, and
even though they propose two types of divine design — a design of
nature, and natural-appearing guidance — the "big tent of Intelligent
Design" isn't big enough for them because, in the mainstream
ID community, detectable
design-directed action is the usual meaning of intelligent
design (ID).
In
everyday life we often see the results of human
design. Everyone
accepts design-action by a natural agent (to explain faces
on
Mt Rushmore,
or
a house, car,...)
when there is evidence, and design theories are common in science. But it's more logically difficult to convincingly show design-action in biology. And
concerns arise when the design-action might be supernatural, and a common
claim is that a design theory is a creation theory. Is
this justified?
A basic design theory claims
only that design-directed action did occur (this is the first stage
in any design investigation, in archaeology, homicide, origins,...) but does
not try to explain the details of how (and by whom, why,...) the design-idea
was converted into a designed feature. Although a basic design theory
can be supplemented with details to form a variety of theories about supernatural creation (by
God or...) or natural non-creation (with evolution
of life on earth directed by space aliens who evolved before us, or...), basic "mere design" does not propose divine action, but
does acknowledge this as a possibility; it does not try to distinguish
between creation and non-creation, it just claims "design did occur" and (as an implicit logical corollary) that the designer had the abilities necessary to conceptualize the feature, and produce it.
Michael Behe, in a supplemented design theory, acknowledges that "most people (including
myself) will attribute the design [of an irreducibly complex biological
system] to God, based in part on other, non-scientific judgments
they have
made." But
as a scientist, in a basic design theory he thinks "the
biochemical evidence strongly indicates design, but does not
show who the designer was."
What are the similarities
and differences between design and creation? Logically,
a design theory is not a creation theory (as explained above) but there
are similarities. Sociologically, there are connections
between design and creation.
Most advocates of Intelligent Design (ID) are monotheists — mainly
Christians, but also Jews and Moslems — who think the designer is God. The "big
tent of ID" includes mainly old-earth progressive creationists (OECs)
and young-earth creationists (YECs), with evolutionary creationists excluded. Most
leaders of ID are OECs who think the earth and universe are billions of years
old, but they welcome YECs into the "big tent" community of ID. Why? OECs
and
YECs both criticize neo-Darwinism and agree that "design-action did occur," and
both (along with evolutionary creationists) oppose an
atheistic worldview. The leaders of YEC have formed an uneasy
semi-alliance with ID, despite its toleration of old-earth views and
its
lack
of
emphasis
on Genesis. / What are the mutual benefits? The
anti-evolution
aspect
of YEC gets a "free ride" from design theories that (since they're
not burdened by connections with weak young-earth science) are
more
scientifically
credible, and are less constitutionally questionable
in American public education. And ID can use YEC support, sociologically
(in the Christian community), financially (in contributions and book sales),
and politically (in education and other areas). / What
are the disadvantages for ID? In the classroom and courtroom
(as
we
saw
in Dover) the potential acceptability of ID is decreased by its connection
with
YEC. And among
scholars,
ID's
strategic alliance with YEC (whose opposition to old-earth science is considered
scientifically
foolish) is a scientific disadvantage for ID.
* Even though OEC accepts
one current scientific consensus
(re:
age)
but
rejects
another (re:
design), old-earth creation is logically
coherent because its acceptance-and-rejection are due to differences
in scientific
evidence (the support for an old earth is very strong, but questions about
design
seem justified)
and theory structure (YEC proposes miracles to overcome weakness in its
own
young-earth theories, but OEC proposes miracles due to weakness in the non-design
theories
it rejects).
In my opinion,
• every scientific
theory should be logically evaluated based on scientific merit,
not motives; evolution should not be rejected because some
of its advocates are atheists, and design should not be rejected
because most of its advocates are theists. { In conventional
scientific method, motivations can influence the proposing of
a
theory
but should not affect its evaluation. }
• sociological
connections between ID and YEC are mostly irrelevant in scientific
debates, because ID arguments assume a conventional old-earth
history of nature; there are many similarities in the scientific
claims of ID and OEC, and in the evidence-and-logic that each claims
as support.
• sociological connections
between ID and YEC are very relevant in education, because much
of the political support for ID in public schools
(for teaching about ID, or allowing criticism of neo-Darwinism) comes
from YECs, and also because
teaching about ID will stimulate questions (both
friendly and hostile) about religion and creation (both YEC & OEC),
which might promote a climate of controversy that most teachers want
to avoid. What
should public schools teach about origins? / Ironically, when YECs "draw a line" at fossil evolution (see 7A below) the plausibility of evolution increases because all of the strong evidence for an old earth becomes evidence for evolution.
• and sociology
of another type is relevant for another question: Proponents
of ID rarely publish in science journals or get research funding,
but is this because their work is worthless, or because the scientific
community doesn't want to acknowledge anything worthy in it?
7. How should we evaluate evolution
and design?
7A — Many meanings of evolution: how to evaluate?
7B — Can we use scientific methods to detect design?
7C — Methodological Naturalism & Design in Science?
7D — Can a Christian use methodological naturalism?
Overview: Sections 7A-7D ask questions about theories
of natural evolution, but don't propose conclusions; instead, the main goal is to examine
the process of logical evaluation.
7A. the many meanings
of evolution — How can we evaluate?
Logical Comparisons: Is a theory proposing
that "John
is an Olympic Weightlifter" supported if we observe that John
can lift a hat and place it on his head? No. But it would
be supported, compared with a theory claiming "John has average
strength,"
by seeing
John lift a heavy weight that's close to the world record. To
distinguish between these competitive theories — Olympic Weightlifter,
Average Strength — we must focus on their differences (they
disagree about John's ability to lift a near-record weight), not their similarities (they
both agree that John can lift the hat).
This principle of logic
can be used for evaluating evolutions:
When we ask "What
is the scientific support for evolution?", we can look at four types
of evolutionary change: astronomical, geological, chemical, and biological.
Most scientists think the support
is very strong for astronomical evolution (in an old universe) and geological
evolution (on an old earth) but is not strong for chemical evolution (of
the first life). And the support varies when we look at four related
aspects of biological evolution (for the development of life):
• micro-E (within
a species) and minor macro-E (to produce
a new-yet-similar species), • fossil-E
progressions (in the geological record), • common
descent (with all species related by shared ancestors), and • Total
Macro-E with all biocomplexity and biodiversity produced
by cumulative effects of macro-E.
also: In biology, evolution is any micro-E
change
in
the gene pool of a population; and scientists propose neo-Darwinian
subtheories for
E-mechanisms (natural selection,...). • In a non-scientific meaning,
some
people — including scientists and nonscientists,
theists
and
atheists — think that evolution is inherently
atheistic because if natural process is sufficient (and God isn't necessary)
this
implies "only
nature
exists" and there is no God.
This table shows whether five aspects of evolution (four scientific
and one non-scientific) are accepted in four views of
creation:
theories of creation:
For each E, does a creation
theory say yes or no? |
creation
by natural
evolution |
progressive
creations by
modification |
progressive
independent
creations |
young-earth
independent
creation |
| • micro-E and minor macro-E |
YES |
YES |
YES |
YES |
| • old earth with fossil-E |
YES |
YES
|
YES
|
no |
| • full common descent |
YES |
YES |
no |
no |
| • natural Total Macro-E |
YES |
no |
no |
no |
| • "only nature exists" atheism |
no |
no |
no |
no |
Splitting "evolution" into components
allows logical comparisons:
In the row for "micro-E and minor macro-E" all theories
agree (YES YES YES YES) so these "evolutions" are
irrelevant for comparing neo-Darwinian evolution with the other three
creation theories.
Evidence for an old earth (with
evolutionary fossil progressions) is not evidence against the two old-earth
progressive creations, which say "YES YES".
Similarly,
evidence for common descent — such as homologous adaptations, "molecular
clock" analyses, and a sharing of genetic code, Hox genes, and
pseudogenes — counts against one old-earth theory (with
independent creations) but not another (with genetic modifications)
because it says YES.
To distinguish between any two theories — whether the question
is weightlifting or evolution — we should compare the competing theories and focus on evidence about disputed
components (where they disagree,
where one theory says YES and the other says NO), not agreements. For
example, most of the common "evidence for evolution" does not support creation
by natural evolution over progressive creations by genetic modification, because
they disagree only about the question of 100%-natural Total Macro-E. / And we should ask separate questions about descent and design. For example, Michael Behe accepts common descent but he challenges Total Macro-E, and proposes Intelligent Design, with
his claims about irreducible complexity. }
And a common argument against
the intelligence of design — as when Stephen
Jay Gould claimed that "God surely would not have
used a collection of parts generally fashioned for other purposes; ... odd
arrangements
and funny solutions [as in the “panda's thumb”] are the proof of
evolution" — assumes the necessity of independent creations,
thus ignoring the possibility
of creations by modification, which is my own view. Gould
boldly asserts that God "surely would not..." as
if he knew that God would want his creative actions to be obvious. (Why
isn't God more
obvious?)
When using a word with many meanings, we should
not mix the meanings. We should not shift evidence for a strongly
supported aspect of E (micro-E,...) onto a less strongly supported aspect
(Total Macro-E) without carefully analyzing the relationships between
different aspects. And we should not
imply that evidence against young-earth creation is evidence against
old-earth progressive creation or Intelligent Design.
Unfortunately, loose logic allows claims that are
bold yet vague, as in declaring that "evolution is a fact"
without defining the meaning of evolution, thus implying that all four types of E are a "fact" with the same high level of certainty. But this is not true.
As explained in the FAQ-Homepage, "within
ASA there is a wide range of strong opinions" about
some questions, including those in 7B-7C (and 5D-5F) so
this is "one ASA-FAQ rather than the ASA-FAQ." { in
ASA, all of us accept
some types of divine design but some of
us don't accept all types of divine design }
7B. Can we use scientific
methods to detect design?
In everyday life, when
we wake up in a house, listen to a radio, read a newspaper, or
drive a car, we
conclude that "the origin of this feature required design." Why? Because
we observe "signs of
design" that
we think could not be produced by the undirected
natural process of non-design, that
in all of our previous experience have been produced
by design-directed action, which seems required to produce
the sign-characteristics. These
inductive inferences to design use valid inductive
logic (based
on past experiences and present observations) and are common in everyday
life and in science.
William Dembski, a prominent
design theorist, describes signs of design in
a more technically sophisticated way, in terms of complex
specified information. A
radio signal with a short string of prime numbers (like "2 3")
is not complex, and it could easily occur by chance. A long
string of random numbers is complex, but is not specified because
it has no pattern or function. But a long string of prime numbers (2
3 5 7 11 13 17,...) is complex and (due to its conceptual functionality)
is specified.
Other types of specification
due to functionality occur when you read a paragraph and understand
the meaning, see a "painting" on the wall of a cave, or when
a combination of parts is a "bicycle" you
can ride to the store.
These common examples are
uncontroversial, and we can infer "design" even if we didn't
observe the designer or design-action. But questions arise when
the design-action seems unfamiliar (so it might be supernatural?) and
we're looking at design in biology. In these situations the main
concerns are religious — Is a design theory a
creation theory? — but critics also have methodological
questions:
Is an argument by analogy
justifiable, in a claim that because scientists confidently infer design
in a common context (for a house, radio signal, cave painting,...)
they should accept the possibility of infering design in a biological
context (when we ask if design-action was required to produce biological
functionality in the first living cell, or in the DNA specifying a functional
protein, biochemical system, or whole organism)?
Those who think detectable Intelligent
Design might have occurred in formative history usually ask questions about biological
evolution and chemical
evolution:
• For
each step in an extrapolation from small-scale
evolution to a large-scale natural production of all biological
complexity (and for this macro-evolutionary scenario as a whole), how many
mutations
and how much selection would be required to produce the
changes
in DNA that we observe, how long would this take,
and how probable is it?
• Are
some systems irreducibly complex (because all
parts are required for the system's function), and could such a system be
produced by a process of step-by-step evolution if there would be no function
to "select for" until all parts are present?
• Could
a nonliving system naturally achieve the minimal
complexity (with hundreds of biomolecular parts) required
to replicate itself and thus become capable of changing, in successive
generations, through natural selection in neo-Darwinian evolution? Based on current science, I think the answer should be "probably not" because scientists are learning that what is required for life seems to be much greater than what is possible by natural process. Then how did life begin? {some possibilities}
Most scientists think neo-Darwinian evolution
could produce all existing biological complexity. Loren Haarsma
& Terry Gray explain why: "We know several
evolutionary mechanisms that increase the size of a cell's genome (e.g.,
gene duplication, horizontal transfer, polyploidy, endosymbiont capture).
Combined with natural selection, this allows information transfer from
the environment to the cell's genome. In addition, the genomes
of living organisms display redundancy and multitasking, allowing for
the evolution of novelty and interlocking complexity. (source)"
And they recognize the limits of current knowledge:
"In order to know whether or not some complex
piece of biological machinery could have evolved, we must know each
species' genetic sequences [by genomic sequencing that has only begun
recently], but also understand in great detail how gene products interact
with each other in living cells." They think that
currently "the jury is still out"
on design questions for biological evolution, but "it seems most promising
— both scientifically and theologically — to study biological
complexity expecting to find more evidence that God designed into it
the ability to self-organize."
Can scientists
correctly evaluate and distinguish between similar
theories such as natural
evolution and creation
by genetic modification? Yes, if they had enough detailed historical
data — such
as lab reports for structure, physiology, and (especially) genome-DNA,
for all organisms during
a period
of change — it
would be easy. But with the data we actually have, it is more difficult.
Logic
and Testing: A particular feature was produced either by detectable
design-directed action (design) or
by what appears to be undirected natural process (non-design). These
two possibilities are mutually exclusive, so
if non-design is highly improbable, design is highly probable. The
evaluative status of non-design (and thus design) can be decreased
or increased by empirical observations, so a theory of design is empirically
responsive and is testable; in terms of probability, which is the usual goal in science, design
is scientifically falsifiable because we can conclude that a design theory is probably
true (if
all non-design theories seem highly implausible) or is
probably false (if any non-design theory seems highly plausible) by using the logic of mutual exclusion.
Can design be proved? No. A design theory does
not claim that non-design is impossible and design is certain, it
only claims that design seems more probable. But proof is
always impossible in science. Instead, scientists try to develop a high
level of logically justified confidence in the
truth or falsity of a theory. Therefore, it seems unreasonable for critics
of design to demand, by using the logic of postmodern skepticism, that if design
proponents cannot claim the certainty of proof, they can claim nothing.
Evaluation of scientific theories is
based mainly on scientific evidence-and-logic, but this evaluation can be influenced by philosophical
perspectives that include decisions about what to conclude when the evidence
is not conclusive. Should we give non-design the "benefit of doubt" and
put the "burden of proof" on design? But instead of declaring
a winner, can we just say "we're not sure at this time" and continue
searching with a humble open-minded attitude, in our efforts to learn more?
We can logically infer design in two ways: with positive design-logic we
recognize "signs of design" as in a house, radio signal, newspaper,
or cave painting; with negative design-logic we
ask whether
a
feature could be produced by non-design, and if we answer "probably
not" then
we conclude it probably was produced by design. These ways of thinking
are related, and a "sign of design" is usually an intuitive recognition/conclusion,
based on experience and logic, that production by non-design (by undirected natural
process) is highly improbable.
Scholars sometimes analyze the process of
science
in terms of invention and justification, with
each having different "scientific method" expectations; the initial
invention of an idea can occur in any way (as when Kekule visualized the structure
of benzene in a dream) but the process of justifying this idea requires scientific
evidence
and
logic. We
can think of positive design-logic as a way to invent a claim for
design,
and negative
design-logic as
an attempt to justify this claim by using scientific evidence and logic.
seven possibilities: Perhaps
a feature, such as the first life (more specifically, the first carbon-based life), was produced by undirected natural
process that seems improbable but • did occur anyway,
or • is actually highly probable because we live in a multiverse*; or
maybe it was reasonably probable and it can be (or could be) described in a naturalistic
theory that • is currently known, or • will be
known in the future, or • will never be known; or
maybe the feature was produced by design-directed action, by • natural
design and construction (by a previously existing form of life that was not carbon-based), or • supernatural design and creation.
All current theories for a natural
evolution of chemicals from nonlife to life seem highly implausible, because what
is necessary (for life) seems much greater than what is possible (by
natural process). Should scientists consider the possibility that design-action
produced the first life? Even though proof is impossible because we can
never propose and test all possible mechanisms for non-design, could we develop
a logically justified confidence that our search has been thorough yet futile,
and no promising mechanisms remain unexplored? And in current science, is the origin of life a test-case for scientific humility? {more about the
origin of life from the faq-author and OTHER
AUTHORS}
* The Anthropic Selection Principle can be used to "beat the odds" and thus neutralize any claim for intelligent design for an origin of life, because this origin is necessary for producing intelligent observers. But a claim for design could still be scientifically supported if, in the future, scientists conclude that a natural origin of life is so improbable that it is basically impossible — analogous to the extreme improbability of a Boeing 747 spontaneously (with no human design-and-production) arising from a garbage dump in Seattle, filling with passengers, and flying to Miami — so this would NEVER happen even in an immense multiverse, and therefore miraculous divine design-action is necessary to form a living organism. But it would be difficult to prove this natural-impossibility in a way that would be accepted by dedicated skeptics — especially if an assumption of immense probabilistic resources (by assuming we live in an immense multiverse) has increased the level of natural-improbability that skeptical scientists will accept as evidence for design — so there is a possibility of divine design-action that did occur but is not acknowledged by skeptics.
And what about Darwin? It also seems justifiable for scientists to consider the possibility of design-action during the process of biological evolution, when we ask questions about evolution rates and irreducible complexity. I say (in Definitions of Irreducible Complexity) that "in 2009 I think 'the jury is still out' when we look for 'proof beyond a reasonable doubt' on a verdict either for or against claims that irreducibly complex biological systems provide evidence for intelligent design."
Future Science
One challenge in evaluating
design is uncertainty about the adequacy of current science. If
our science becomes more adequate in the future, will non-design seem
more plausible because we have discovered how natural process could produce
a feature? Or will non-design seem less plausible — as with
chemical evolution in the 56 years since the Miller-Urey experiments
inspired naturalistic optimism — because we have learned more about
the limits of natural process?
What will happen? We can
try to predict improvements in current theories and inventions
of new theories, by using current knowledge (*)
plus creative thinking (to imagine what could be) and critical thinking (to
predict what is probable in reality, not just possible in our imaginations)
so we can avoid the extremes of insisting that "nothing new will happen" or "anything
could happen." / * For
example, we can "critically imagine" how future knowledge might
change our views about each obstacle to a natural origin of life: the unfavorable
reactions for chemical synthesis, the biocomplexity required for life,...
Imagine a "super science" developed
by trillions of super-intelligent space aliens who have studied biochemistry
for billions of years, have explored the universe searching for life and environments
for producing it, but have not yet constructed a plausible theory for a natural
origin of life. Even with this knowledge a denial of design would be
possible, but would it be rational?
Compared with this imaginary
super-science, in the near future the actual state of human knowledge will
remain much less advanced. For awhile, scientists will continue to
disagree about the plausibility of design, but this is healthy for science
when it stimulates thinking and discussions between advocates for different
points of view. Proof is impossible in science, and it can be difficult
to confidently answer the question, "Was design involved in
producing this feature?" Although it should be easier to decide, "Should
we ask the question?", there are also vigorous debates about
this, as you'll see in Sections 7C and 7D, which ask "Should we
include design in science?" and "Can a Christian use methodological
naturalism?"
comments about completeness: In this condensed Overview-FAQ,
Section 7B has omitted many details (in what you've read above) and
some important questions — about intelligence (how much is necessary for design? is Hoover Dam designed? what about a beaver
dam? or an ant hill?) and intention (is industrial water
pollution a result of design-action if it was unintended? if it was predictable and was thus intentional?), competence (as in “panda's
thumb” questions about "improvised problem solving" during evolution)
and compassion (why does nature include mosquitoes and deadly
viruses?), goals and abilities of the designer (must we know these before concluding "this
feature was the result of design"? I say "no" because if a designed feature exists we can infer the goals and abilities), what are the probabilities of false negatives (by
concluding "no
design" when
there was design) and false positives (concluding "design" when
there was no design) — and
you can explore these extra ideas from
7B (plus additional ideas
from
7A,
7C, and 7D)

Evolution and Design.
7C. Is methodological naturalism useful in
science?
Should intelligent
design be allowed in science?
Currently, most scientists use methodological
naturalism (MN) by including only
natural cause-and-effect in their scientific theories. Is it
necessary for a scientist to always conclude, for everything in the history
of nature, that "it happened by natural process"? This assumed conclusion produces an inflexible Closed Science that is constrained, in its search for truth, by rigid-MN. In a rational alternative, a flexible Open Science uses testable-MN in
which a scientific investigation begins by assuming "it happened by natural
process" but considers this a flexible assumption that can be tested, not a rigid conclusion that must be accepted.
If we define science as "whatever
scientists do," and most scientists currently use methodological
naturalism (MN), does this make it scientific? If those with power
to make decisions (about publishing, funding, and hiring) decide that
MN is a "rule of science" that is unwritten yet is enforced,
does this settle the issue?
Is science a game with rules? This is an interesting
sociological perspective, useful for thinking about interpersonal dynamics and
institutional structures. But instead of viewing science as a game with
rules, we should think of it as an activity with goals. *
For most scientists the main goal of science (although
not the only goal) is finding truth about nature. But rigid-MN might
lead to unavoidable false conclusions. When some scientists recognize this
and question the usefulness of rigid-MN, is it cheating or wisdom?
* The full page compares "cheating" in
two contexts — is it acceptable to move a refrigerator using a two-wheeler
if the goal is recreational (as in a strong-man competition) or is pragmatic (in a business that delivers appliances) — and
asks "which of these is closer to the main goal of science?" More generally, scientists and their problem-solving
methods — including logical reality
checks and cultural-personal factors, and
much more (but not rigid methodological naturalism) — are examined in a set of pages, condensed from my PhD dissertation,
about scientific
method.
If "the
main goal of science is finding truth about nature," perhaps
with rigid-MN this search is occasionally futile,
like trying to explain how the faces on Mount Rushmore were produced
by natural processes of erosion. If
scientists are restricted by an assumption that is wrong — that
does not match the historical reality — their finest creativity
and logic will fail to find the true origin of the faces. { The
full page asks you to "think about a man who
is looking for missing keys in the kitchen when the keys are on the front
porch" and suggests that "when
we're not sure where the keys are, instead of demanding an either-or
choice (by restricting the search to either kitchen or porch)
it seems more rational to search everywhere, in both kitchen and porch." }
In science, is rigid-MN a useful strategy? Probably
it will be useful IF its assumption (that history included only natural events)
matches reality, since rigid-MN will help scientists avoid being distracted by
false theories about non-natural events. But IF non-natural events really
did occur in history, so the premise of MN is false, rigid-MN will force scientists
to reach some false conclusions, and this doesn't seem useful.
We don't know whether MN matches the reality of history,
so should we search with a humble attitude by refusing to assume that we already
know — with certainty, beyond any doubt — what happened? Should
we assume answers, or investigate questions?
Criteria for Defining Science?
Falsifiable: Sometimes a theory of design is criticized by claiming it is not scientific because it is not falsifiable. But this claim seems wrong, for two reasons. First, most philosophers of science think it is impossible to define science, and to separate science from non-science, on the basis of specific criteria such as falsifiability. Second, a design theory can be empirically responsive, testable, and scientifically falsifiable, by using the logic of mutual exclusion. Even though in science we cannot prove or disprove any theory, we might be able to develop a logically justified confidence that a specific design theory is probably true or is probably false.
Predictive: Should a design theory be labeled "unscientific" because it does not make predictions? This demand is silly for any theory making a claim about history. The goal of historical science is to describe what did happen in history (not to predict what will happen in the future) and it can describe one-time
events. To see how silly this demand for "prediction" is, imagine claiming that a meteor-extinction theory (proposing that dinosaurs became extinct due to a giant meteor impact 65 million years ago) is unscientific because it cannot predict this event.
Mechanistic: In some situations, a mechanistic
explanatory theory can provide an adequate description and explanation. But in
other situations, "what happens" depends on the decisions and
actions of an agent, so a historical theory that is accurate (because it correctly describes what actually happened) must be an agency explanatory theory — proposing that "agent action was involved" — instead of a mechanistic theory that ignores the agent.
If miracles occur, as claimed in the Bible, is
science still possible? Yes. Effective science requires
a world that is usually natural (without frequent "Alice in Wonderland" surprises) but it doesn't have to be always
natural.
Can non-natural events be studied
using the methods of science? In some ways, no. But in other ways,
yes. Scientists can infer an unobservable cause (such as electrons
in chemistry, or ideas in psychology, or the actions of an unseen agent) if
the unobservable cause produces observable effects.
Can we predict or explain the actions of a supernatural agent? No. In this area of reality, we have a limited understanding. But these limitations are not reasons to think a basic design theory (which only claims "design-action did occur") is unscientific, because in historical science it's unreasonable to demand that a theory must be predictive or mechanistic, as explained above.
Should we define science as a search
for natural explanations, or a search for logical explanations? If
there is a conflict between natural and logical — if Methodological Naturalism says "for
this question we must accept a natural conclusion even though evidence-based
logic doesn't support it" — which criterion should have higher priority?
But in natural science,
don't we have to explain natural phenomena and natural history
by natural causes? No, this claim is just
circular logic that's camouflaged with verbal ambiguity by using natural to
mean both "pertaining to nature" (three times)
and "normal appearing" (once).
A
principle of methodological naturalism cannot be derived
from science (so it is non-scientific)
but is compatible with science (so it is not
un-scientific).
Design in Science?
Should intelligent design be allowed in science? This
section builds on 7B which asks, "Can
we use scientific methods to detect design?" and observes
that "scientific theories are evaluated based
on scientific evidence-and-logic combined with philosophical
perspectives" that include the option of deciding that "instead
of declaring a winner, we can just say ‘we're not sure at this
time’ and continue searching, with a humble open-minded attitude,
in our efforts to
learn more."
A basic design theory (which
claims only that "design did occur") does not explicitly propose supernatural
action, but — since design-action can be either natural (as in genetic
engineering) or supernatural (as in miraculous biblical healings) — it
implicitly acknowledges the possibility of divine action, so design isn't limited
by the philosophical assumptions and methodological limitations of rigid methodological
naturalism.
If some scientists think "a designer
did it," will this stop scientific progress because there is nothing left
to study? No. Design is not a science-stopper, because when most
scientists hear a claim that "maybe a non-design explanation doesn't exist" they
will continue their non-design research, probably with renewed vigor because
they are responding to a challenge.
Most biologists think non-design
research, based on neo-Darwinian theories, is more productive for helping us
understand the history of life. I agree. But design can also be
scientifically useful when the perspectives of design and non-design are combined,
with creative-and-critical thinking (in non-design) supplemented by additional
critical thinking (in design); and design can promote creative thinking
by its proponents & opponents.
We don't have to make an either-or
choice between design and non-design. Proponents of design want non-design
research to continue and prosper so we can learn
more, so in future science we can better evaluate the
merits of non-design and design, because the goal is to find truth. Design proponents
want to supplement non-design research, not replace it. They want to
stimulate productive thinking and action (this has occurred due to Michael
Behe's claims for irreducible complexity) with invigorating debates between
critics of a theory and its loyal defenders (but this
has not occurred in science journals).
Design will have little overall
impact on science, because most areas are not affected by claims for design. But
for some questions about origins of the universe, first life, and complex
life, maybe design deserves to be viewed as a potentially useful idea,
worthy of serious consideration and further development.
Due to circular logic, The
Assumption of MN — that no matter what the evidence indicates, "it
happened by natural process" — automatically
becomes The Conclusion of MN. Of course, the irrelevance
of evidence does not mean there is no evidence, or that MN is leading
to the wrong conclusion. But it does illustrate a logical weakness
of MN, which bypasses the process of science and then (by ignoring
MN-Humility) claims the authority of science for its
naturalistic conclusions.
Are scientists "unscientific" if
they strongly criticize chemical evolution by describing the inadequacy
of all current theories? or if they claim that future theories will also
be inadequate? or
propose a design theory that implies a non-natural cause? or explicitly
propose a non-natural cause? But if a critic proposes a new naturalistic
theory, does this make the criticism scientific?
Can scientists admit that "we
are far from finding the answer" but not that "maybe there is
no natural answer"? Should we use rigid-MN to restrict the freedom
to propose that "maybe..."? Or should we let scientists
use the entire process of science, including a logical evaluation of all
competitive theories, when they are determining the conclusions of science?
7D. Methodological Naturalism: Can a Christian
use it?
The Bible claims that God does miracles. Should
a Christian use methodological naturalism (MN)
and assume "no miracles
in the history of nature" while doing science? Is
methodological naturalism theologically satisfactory? Yes, I think
devout Christians can use MN in two ways:
• Proponents of an open search accept
rigid-MN in science, but view the resulting closed MN-science as one aspect of a broader "open search for truth" that
considers all possibilities, including miracles. MN-science
is respected as an expert witness, but is not allowed to be the judge and jury
when we're defining rationality and searching for truth.
• Proponents of open science claim
that historical science would be more effective, in a search for truth, if we
replace rigid-MN with testable-MN in
which a scientific investigation begins by assuming "it happened by natural
process" but considers this an assumption that can be tested, not a conclusion
that must be accepted.
In both approaches, natural does not mean
without God.
Confusion is
caused by the common use of "naturalism" with two
meanings: In a narrow meaning, naturalism is
a specific claim — which is compatible with Christianity — of "only
natural process" for a particular event, series of
events, or period of history; this type of narrow claim can be affirmed by a wide
range of people, including Christians and non-Christians. In a broad meaning, NATURALISM is
a general claim — not compatible with Christianity — that "only
nature exists" or "only matter/energy (and related
forces) exists" with no God and thus no divine action; this broad claim is affirmed by a narrow range of people that does not include Christians.
When
one word has two meanings, this often leads to sloppy thinking
and communicating, so I think we should avoid using naturalism with the broad meaning, NATURALISM. Instead, the atheistic claim that "only
nature exists" or "only matter exists" should
be called naturism or matterism or materialism. {the
frustration of multiple
meanings & stolen words}
Do you see the two differences between methodological naturalism and philosophical naturism?
An open science is not theistic science.
A theistic science is based
on the principle that theists should use all they have reasons to believe (including
their theology) when doing science, when constructing and evaluating theories. But
theistic science is not a single way of thinking, because our differences — when
interpreting the Bible (in theology) and nature (in science) and combining these
interpretations — can lead to different ideas about God, scripture, divine
actions, nature, and science, which can produce dogmatic rigidity (ranging
from extremes of young-earth geocentrism to evolutionary deism) or open-minded
flexibility.
But everyone, whether they are a theist or nontheist,
has a
worldview that influences their science and their willingness to "follow
the evidence" to a logical conclusion. For example, an atheist
can accept only
one
conclusion — a totally natural evolution
without
God — so their scientific freedom is limited.
An open science welcomes all
perspectives — including atheism, agnosticism, pantheism, and theistic
sciences with differing views about MN and about questions of age and evolution — but
is not restricted by the dogmatism of any perspective, so it can maintain an
open mind about a wider range of scientific conclusions.
With methodological naturalism
the inevitable scientific conclusion for every question — no matter
what is being studied, or what is the evidence — must be that "it
happened by natural process."
Scientists who use MN, which places a limit on what can
claim to be science, automatically place a limit on what science can
claim to explain. Why? Because MN logically
requires MN-Humility that acknowledges the possibility
of unavoidable error: If the origin of a feature involved a non-natural
cause, then any explanation by MN-Science (in terms of only natural causes) will
be incomplete or incorrect.
In principle, an open search that combines MN-Science
with MN-Humility is logically and theologically acceptable. In practice,
a weakness of this combination is the rarity and futility of humility.
MN-Humility is rare. Christian scholars who advocate
an open search rarely ask their colleagues to consider the possibility that MN-Science
can err (in general) or might have erred (in a specific situation) by reaching
a wrong conclusion. And non-Christian scholars are even less likely to
be humble about MN-Science. / Consider this example: Theories about a natural origin
of life (NOOL) are an especially interesting "test case" when we ask questions about MN-Humility,
because scientific support for NOOL-producing chemical evolution is
much weaker than for biological evolution, and (unlike biological evolution)
NOOL is not important for biological science; but NOOL is necessary for a formative history of nature without miracles (which is assumed in MN-Science, and is proposed by evolutionary creationists) and, in a more extreme claim, for a world without God (as proposed in the philosophical
naturism of atheists). NOOL is an opportunity for MN-Humility. But instead of a humble acknowledgment that maybe life did not begin by a natural process that is part of MN-Science, there are confident statements — by individuals and organizations, in textbooks, educational films, and websites — implying that chemical evolution did produce life, even though we don't yet know the details of how this happened.
MN-Humility is futile in producing a "level playing
field" for evaluations, even when it is acknowledged. Why? Think
about what happens when a "scientific" theory and a "nonscientific" theory
both claim to describe some feature in the history of nature. Even if scientific evidence does
not support the scientific theory (as with a natural origin of life) it
is considered more plausible due to the cultural authority of
science. The nonscientific theory is not respected because in modern society most
people assume that, for a theory about nature, "not scientific" means "not true."
Usually, thinking that "scientific" means "probably true" is a good way to bet. Our confidence in science is generally justifiable, because science based on evidence-and-logic has been very useful for understanding nature and developing technology. But MN-Science is not constrained by evidence and logic, since the unavoidable conclusion (independent of evidence) is that "it happened by natural process." Thus, MN-Science can bypass the process of science and then claim the authority of science for its naturalistic assumptions that, due to the rarity and futility of MN-Humility, appear to be scientific conclusions.
Does methodological naturalism influence the way we think? In principle, scientific methodology and philosophical worldviews can be
independent. But in practice they are mutually interactive and each tends
to influence the other. Methodological naturalism can influence our thinking because
its naturalistic assumptions automatically become naturalistic conclusions about "the
way the world is (regarding what can and cannot happen) according to science," and
many people are influenced by science.
8. Wise Education about Creation and Origins
The title above is not a link because this is the only page
in the FAQ that isn't written yet. Maybe something more will be available
by mid-2010. Until
then, in my Introductory FAQ you can see some questions it will address; and many of the ideas that eventually will be in it are already in the homepage
for ORIGINS
EDUCATION.
8A. What should Christians teach about creation?
When this section is written, it will use the earlier FAQ-pages (1-7)
as a foundation for understanding creation — who, why, what, when,
and how — and what to teach about it. And it will include
many ideas that are now in CHRISTIAN
EDUCATION.
8B. What should public schools teach about origins?
Until this section is written, you can read the links-page for ORIGINS
EDUCATION IN PUBLIC SCHOOLS (written by me as editor) and my own
page (written as author, not editor) for Critical
Thinking (about Creation, Evolution, and Intelligent Design) in Public
Schools.
