The human race is not divided into the irrational and the rational, as some idealists think. All humans are irrational, but there are two different kinds of irrationality - those who love old ideas and hate and fear new ones, and those who despise old ideas and joyfully embrace new ones. Homo neophobus and homo neophilus. Neophobus is the original human stock, the stock that hardly changed at all for the first four million years of human history. Neophilus is the creative mutation that has been popping up at regular intervals during the past million years, giving the race little forward pushes, the kind you give a wheel to make it spin faster and faster. Neophilus makes a lot of mistakes, but he or she moves. They live life the way it should be lived, ninety-nine percent mistakes and one percent viable mutations.
