Alternate Vision

Biological evolution is to a large extent a history of escapes from the blind alley of overspecializtaion, the evolution of ideas a series of escapes from the tyranny of mental habits and stagnant routines. In biological evolution the escape is brought about by a retreat from the adult to a juvenile stage as the starting point for the new line; in mental evolution by a temporary regression to more primitive and uninhibited modes of ideation, followed by the creative forward leap.
