The key question, it seemed to him, was that of whether man was to obey Nature, or attempt to command her. It had been answered long, long ago, claimed Moss; man's very essence lay in the fact that he had elected to command. But to Stenham that seemed a shallow reply. To him wisdom consisted in the conscious and joyous obedience to natural laws, yet when he had said that to Moss, Moss had laughed pityingly. 'My dear man, wisdom is a primitive concept,' he had told him. 'What we want now is knowledge.' Only great disillusionment could make a man say such a thing, Stenham believed.
