I believe that a normal man is one being, manifesting himself in various aspects, physical, emotional, intellectual. I believe that all these aspects of human activity go normally together, and cannot normally be separated, and that the separation of them is a perversion and source of harm. I believe that the sex impulse, as it normally manifests itself, and would manifest itself in a man if he were living a normal life, is an impulse which includes every aspect of the man's being. It is not merely physical desire and emotional excitement; it is intellectual curiosity, a deep and intense interest, not merely in the body, but in the mind and heart and personality of the woman. I appreciate that there is opportunity for controversy here. As a matter of psychology, it is not easy to separate instinct from experience, to state whether a certain impulse is innate or acquired. Some may argue that savages know nothing about idealism in sex, neither do those modern savages whom we breed in city slums; some may make the same assertion concerning a great mass of loutish and sensual youths. We have got so far from health and soundness that it is hard to be sure what is "normal" and what is "ideal." But without going into metaphysics, I think we can reasonably make the following statement concerning the sex impulse at its first appearance in the average healthy youth in civilized societies; that this impulse, going to the roots of the being, affecting every atom of energy and every faculty, is accompanied, not merely by happiness, but by sympathetic delight in the happiness of the woman, by interest in the woman, by desire to be with her, to stay with her and share her life and protect her from harm. In what I have to say about the subject from now on, I shall describe this condition of being and feeling by the word "love."
