Very few ever fully appreciate the powerful influence which sexuality exercises over feeling, thought, and conduct, both in the individual and in society. Schiller, in his poem, “Die Weltweisen,” recognizes it with the words:— “Einstweilen bis den Bau der Welt Philosophie zusammenhält, Erhält sie das Getriebe Durch Hunger und durch Liebe.”[1] It is remarkable that the sexual life has received but a very subordinate consideration on the part of philosophers. Schopenhauer (“The World as Will and Idea”) thought it strange that love had been thus far a subject for the poet alone, and that, with the exception of superficial treatment by Plato, Rousseau, and Kant, it had been foreign to philosophers. What Schopenhauer and, after him, the Philosopher of the Unconscious, E. v. Hartmann, philosophized concerning the sexual relations is so imperfect, and in its consequences so distasteful, that, aside from the treatment in the works of Michelet (“L’amour”) and Mantegazza (“Physiology of Love”), which are to be considered more as brilliant discussions than as scientific treatises, the empirical psychology and metaphysics of the sexual side of human existence rest upon a foundation which is scientifically almost puerile.
