Well, as Matt Young says in
Richard Feynman on Intelligent Design:
"Richard Feynman, as far as I know, never commented on intelligent design."
and I can say the same. But the above-linked post contains much of Feynman's thoughts on the character of science and is certainly apropos to the evaluation of ID. If you haven't read
The Character of Physical Law (which is much heavier fare than "Surely You're Joking" and much lighter fare than the Red Books), you have
got to read the small portion of it that's quoted in the above-linked post. And, if you've read it before, then, heck, read it again. It's worth it.
{Cue spooky music} And I
just started re-reading "The Character of Physical Law" a few days ago!. It's paranormal, I tell ya ...
