The impulse to think, to philosophize and spin beauty and brilliance out of mind and soul, is somehow the offspring of resistance of an effort to overcome an apparently insurmountable obstacle. Hence cultural creativeness is more likely to flourish in an atmosphere of restriction, of an imposed pattern of thought and behavior, than in one of total freedom.
