There is a huge contradiction. If God's will and intentions are ultimately
unknowable, then the question of His existence will forever be beyond
the boundaries of scientific investigation. And this provides an easy
tool for Creationists to deal with any inconsistencies in their theory
by saying, "well, God works in mysterious ways!" This is what leads to
bad science.

No, but if you are arguing that imperfect designs are deliberate, then
you should be able to back up that argument by providing some good
reasons why an imperfect design was employed when a perfect one would
have been just as easy.

SJ>The argument from imperfection assumes incorrectly that the Designer

No, it assumes that the person arguing intelligent design should be
able to provide a good argument for it.

How would it give us an "overwhelming advantage" over squids if we
were to have the same anti-blindspot retinal design that they do?

Besides, if God's goal has been to prevent any species from achieving
an overwhelming advantage over another, then He has failed numerous times,
according to both the fossil record and many direct observations.

"may be" does not constitute a strong scientific argument.

An interesting example, but I fail to see how it applies to, say, the
placement of blood vessels on a mammalian retina, or the pathway of the
human urethra, or any of the other examples that I've read about.

We know when a feature causes an inherent disadvantage (such as the
blindspot in mammals, or the dangerous layout of the human urethra,
which makes it prone to blockage when the prostate swells), and many
of these features cannot possibly be seen as an advantage. However,
if Behe, Stephen Jones, or anybody else has examples of how such
features might prove advantageous in "the big picture", they are welcome
to present that evidence.

SJ>In fact, the argument from imperfection assumes without warrant that

It only assumes a certain level of common sense. Surely an omnipotent
being would be capable of that.

And even we fallible, imperfect humans can see ways that life could
