Then de Beauvoir proceeds to the human being, comparing the physiology of men and women, and saying that women are weaker than men (for example, in muscular strength, with fewer red blood cells, and a lesser respiratory capacity).[6] In chapter 2 "The Psychoanalytical Point of View", de Beauvoir first expounds the theories of Sigmund Freud and Alfred Adler.
