Over immense periods of time the intellect produced nothing but errors. A few of these proved to be useful and helped to preserve the species: those who hit upon or inherited these had better luck in their struggle for themselves and their progeny. Such erroneous articles of faith... include the following: that there are things, substances, bodies; that a thing is what it appears to be; that our will is free; that what is good for me is also good in itself.
Friedrich NietzscheHow did reason come into the world? As is fitting, in an irrational manner, by accident. One will have to guess at it as at a riddle.
