"The many modern critics who sense an inconsistency in the belief that free creation takes place within — presupposes, in fact — a system of constraints and governing principles are quite mistaken: unless, of course, they speak of "contradiction" in the loose and metaphoric sense of Schelling, when he writes that "without the contradiction of necessity and freedom not only philosophy but every nobler ambition of the spirit would sink to that death which is peculiar to those sciences in which that contradiction serves no function." Without this tension between necessity and freedom, rule and choice, there can be no creativity, no communication, no meaningful acts all all."
