" The inorganic world out of which life has emerged and into which, in season, it falls back, possesses the latent capacity for endless ramification and diversity. A few chance elements which appear thoroughly stable in their reactions dress up as for a masked ball and go strolling, hunted and hunter together. Their forms alter through the ages. They are shape-shifters, role-changers. Like flying lizard or ancestral men, they run their course and vanish, never to return. The chemicals of which their bodies were composed lie all about us but by no known magic can we return a lost species to life. Life, in fact, is the product of singular and unreturning contingencies of which the inorganic world disclaims knowledge. Only its elements, swept up in the mysterious living vortex, evoke new forms, new habits, and new thoughts. "
