To the modern man it seems simply natural that an ordered cosmos should emerge from chaos, that life should come out of the inanimate, reason out of instinct, civilisation out of savagery, virtue out of animalism. This idea is supported in his mind by a number of false analogies: the oak coming from the acorn, the man from the spermatozoon, the modern steamship from the primitive coracle. The supplementary truth that every acorn was dropped by an oak, every spermatozoon derived from a man, and the first boat by something so much more complex than itself as a man of genius, is simply ignored.
