" As a matter of selective necessity, man is an agent. He is, in his own apprehension, a centre of unfolding impulsive activity—“teleological” activity. He is an agent seeking in every act the accomplishment of some concrete, objective, impersonal end. By force of his being such an agent he is possessed of a taste for effective work, and a distaste for futile effort. "
