The decline in Freud's reputation has been attributed partly to the revival of feminism. Simone de Beauvoir criticizes psychoanalysis from an existentialist standpoint in "The Second Sex" (1949), arguing that Freud saw an "original superiority" in the male that is in reality socially induced. Betty Friedan criticizes Freud and what she considered his Victorian view of women in "The Feminine Mystique" (1963). Freud's concept of penis envy was attacked by Kate Millett, who in "Sexual Politics" (1970) accused him of confusion and oversights. In 1968, the US-American feminist Anne Koedt wrote in her essay "The Myth of the Vaginal Orgasm:" "It was Freud's feelings about women's secondary and inferior relationship to men that formed the basis for his theories on female sexuality. Once having laid down the law about the nature of our sexuality, Freud not so strangely discovered a tremendous problem of frigidity in women. His recommended cure for a woman who was frigid was psychiatric care. She was suffering from failure to mentally adjust to her 'natural' role as a woman."Naomi Weisstein writes that Freud and his followers erroneously thought his "years of intensive clinical experience" added up to scientific rigor.
