Ah, we are now running into the ambiguity of the word "logic", which I use
to include probabilistic logic, which includes Bayes' Theorem and the other
results of elementary probability theory.

This sounds about the same to me as Eliezer's "whatever works."

So, then, given that I have a human brain with its ensuing strengths and
limitations, if I rely largely on emotion to drive me in producing a piece
of music or in guiding me through a mathematical proof, according to your
view what I'm doing is being "rational." I'm being "rational" because by
letting emotion guide me, I am achieving my goal of constructing music or
mathematics meeting certain criteria.

And similarly, when my dog chases a female dog in heat, based on his
attraction to her smell, and then proceeds to hump her vigorously, he is
behaving rationally, because he is doing something that produces the right
answer for him, i.e. it achieves his goal of getting nookie. His heuristic
"smell it, chase it, hump it" consistently produces the right answer for
him. It's not a perfect heuristic -- it would be fooled by an appropriate
pheromone-generating machine -- but it works pretty well in reality.... Yet
it just doesn't feel right to me to say the dog is being "rational" in this
case...
