For there is not a single human being, not even the primitive Negro, not even the idiot, who is so conveniently simple that his being can be explained as the sum of two or three principal elements; and to explain so complex a man as Harry by the artless division into wolf and man is a hopelessly childish attempt. Harry consists of a hundred or a thousand selves, not of two. His life oscillates, as everyone's does, not merely between two poles, such as the body and the spirit, the saint and the sinner, but between thousand and thousands.
