I've always been somewhere between bottom-up and top-down; I
don't think of the brain as "one big pattern catcher" but I
don't think it's "Cyc + natural selection" either.

Yes, but doesn't your position suggest a more homogeneous
brain, which seems at odds with pre-wired instincts? This
is the problem I see: there's a trade off between
specificity and constraint on the one hand and generality
and adaptability on the other hand. That is, I can either
have a "fragile" brain where I can make specific changes, or
a flexible brain where I can only make very general changes.
(I tend to think of Cyc and "pattern catchers" as being
opposite extremes in this spectrum.)
