Einstein's quote of "The most incomprehensible thing about the universe is

Has a clear definition of methodological naturalism been established yet in
this discussion?

If it is a working assumption, used in the process of a scientific
investigation, that God has run the system under consideration by natural
laws, then there is no philosophy involved except the belief that miracles
are rare in nature. This belief is true of both the Biblical account and
more recent observations. To extrapolate total absence of miracles, as
Hume, is to commit a logical fallacy of the sort recently discussed in
Science, by which one set of letter writers concluded that the pope is an
alien. In this context, it is worth noting that evolution by natural
selection was proposed before Darwin as a way God had created life.
Darwin, and more flagrantly Huxley, had rejected Christianity prior to
adopting an evolutionary viewpoint, so it's not surprising that their
philosophies colored their presentation.

This is philosophical naturalism. Methodological naturalism cannot say
whether methodological naturalism applies to a given situation, if it is a
method-this requires philosophical input.

You've not talked with the right people if you have not found any.

It tells me that the many verses on the frequent conflict between worldly
wisdom and faith are true. Christians are not currently prominent in much
of academia, so a paucity in evolutionary biology is not especially
significant.

Morality is not a scientifically testable quantity. Only after you
make the metaphysical (philosophical or religious) statement "Scientific
evidence of this sort has this moral implication" can science have any
bearing on moral issues. The philosophical assumption that all human
behavior can be explained by natural selection and other evolutionary
processes is where the conflict with faith arises. It would be possible to
study the relationship between natural selection and moral issues from a
Christian point of view, seeking a better understanding of moral strengths
and weaknesses that involve our evolutionary heritage. For example, the
importance of reproduction to evolutionary success, in combination with our
fallen nature, means that sexual sin is likely to be strongly tempting.
Many scientists and non-scientists alike try to excuse immoral
behavior or rejection of God "because of evolution". This sort of
"evolutionary" morality consists of selective use of garbled bits of
evolutionary ideas and is not a true application of the moral standard
"Everyone should seek to promote his own evolutionary fitness". Communism,
Nazism, and social Darwinism are examples of such purportedly
"evolutionary" systems that do not fit modern evolutionary theory.
However, there are actual studies of the question "Does this
particular moral standard make sense in the context of natural selection?"
Even some of these are questionable, starting from the premise that it has
to have an evolutionary explanation rather than testing it in any way. For
example, if kin selection allows a quarreling primitive tribe to split by
degree of relationship when they do not have words distinguishing the
relevant degrees of relationship, yet also (by mistake) causes caring for
pets, kin selection is being used as an evolutionary panacea. One more
rigorous study of this sort examined the incidence of rape. Rapists are
generally males unlikely to attract a wife; rape victims are generally
women in prime childbearing years. Thus, it is plausible that rape is
influenced by the evolutionary goal of passing on one's genes.
Such studies cannot asses whether evolutionary considerations are
adequate for constructing a moral system. As the example of rape shows,
few people would be satisfied with an actual standard of "Anything that
promotes one's evolutionary fitness goes." "Anything that promotes my
evolutionary fitness goes" is more popular in practice, but is generally
recognized as bad in theory.
Based on his presuppositions, perhaps Wilson "should" try to
explain all human behavior evolutionarily, but not all of it actually is
amenable to such an explanation. Also, the lack of justifiable moral
standards that results from such a worldview is not truly accepted by
anyone. "I can do as I please" is always popular, but when what pleases
someone else displeases you, absolutes quickly reappear.
