On knowing that One is Irrational
Can one know that one is irrational? It seems contradictory; but suppose I believe that I'm the product of billennia of natural selections—that my most basic concepts, and ways of reasoning (and of judging, and so forth), were probably just the normal ways in which human brains happen to make sense of sensory information, having been selected (from random variants) for not being ways that led more primitive brains (of apes, rats, fish and so forth) into inviability; and also that knowledge was one such concept, one fuzzily orientated towards experts (social authorities) and what they tell us, rather than infallibility. I might then believe that I knew that I was irrational.
