Surrounded by a world full of wonder and forces, whose law man may define, may want to understand but never decipher, which reaches him in only a few fragmentary harmonies and which suspends his soul in a continuous state of unresolved tension, he himself conjures up the missing perfection in play. He makes himself a tiny little world in which the cosmic law is evident within strict lim- its, yet complete in itself and perfect in this respect: in such play, man satisfies his cosmogonic instinct.
