According to the linguist Chomsky, human language is the result not of a gradual Darwinian-type genetic evolution, but of a rapid conversion of the existing brain to a new use. I accept this hypothesis of Chomsky's, and suppose that it implied the formation of a linguistic, and therefore digital, brain alongside and in opposition to the preceding analogical brain. This opposition consisted of deflecting and even blocking ancient instincts, and the consequence was that two different strategies now shared the same organism: the ancient instinct and the emerging culture. This required a centre of coordination, which much later would be called the mind. This innovation, the doubling of the brain, was a success, separating humans from the animal world and making them Luciferian creatures. It was indeed too successful: the Greeks called it "Hybris", which imposes a painful process of rebalancing, as in the tragedies of the Fifth Century BC in Athens.
