Anthropology, biology, physiology, psychology have brought together mountains of material to set before man, in all their scope, the tasks of his own bodily and spiritual improvement and his further development. By the brilliant hand of Sigmund Freud, psychoanalysis lifted the lid from the well poetically named the human “soul”. And what appeared? Our conscious thought constitutes only a small part of the work of the dark psychic forces. Learned divers descend to the bottom of the ocean and photograph mysterious fish. For human thought to descend to the bottom of its own psychic well, it must illuminate the mysterious driving forces of the soul and submit them to reason and will. When he has finished with the anarchic forces of his own society, man will work on himself in the mortars, in the retorts of the chemist. For the first time, humanity will consider itself as raw material.
