It has been claimed on this site that the fundamental question of rationality is "What do you believe, and why do you believe it?".
A good question it is, but I claim there is another of equal importance. I ask you, Less Wrong...
What are you doing?
And why are you doing it?
"Define And thus expunge The ought The should ... Truth's to be sought In Does and Doesn't "
-B. F. Skinner (an interesting soundbite from an otherwise misguided disagreement with Chomsky over language acquisition)
