“I have touched before on the idea that a rationalist must have something they value more than “rationality”: the Art must have a purpose other than itself, or it collapses into infinite recursion. But do not mistake me, and think I am advocating that rationalists should pick out a nice altruistic cause, by way of having something to do, because rationality isn’t all that important by itself. No. I am asking: Where do rationalists come from? How do we acquire our powers? It is written in Twelve Virtues of Rationality:” (Eliezer Yudkowsky, Rationality)
