It is true ... that in recent times civilized man has acquired a certain amount of will power, which he can apply where he pleases. He has learned to do his work efficiently without having recourse to chanting and drumming to hypnotize him into the state of doing. He can even dispense with a daily prayer for divine aid. He can carry out what he proposes to do, and he can apparently translate his ideas into action without a hitch, whereas the primitive seems to be hampered on each step by fears, superstitions, and other unseen obstacles to action. The motto "Where there's a will, there's a way" is the superstition of modern man.
Yet in order to sustain his creed, contemporary man pays the price in a remarkable lack of introspection. He is blind to the fact that, with all his rationality and efficiency, he is possessed by "powers" that are beyond his control. His gods and demons have not disappeared at all; they have merely got new names. They keep him on the run with restlessness, vague apprehensions, psychological complications, an insatiable need for pills, alcohol, tobacco, food -- and, above all, a large array of neuroses.
