As presented here, Adler’s emphasis on the equality of the sexes and his innovative concept of the “masculine protest” provides the basis of present-day considerations of the dynamics of sexuality, love and marriage. Co-operation Between the Sexes remains in many ways a modern work by a writer whom Gordon Allport called “one of the wisest psychologists of this century.” In this volume, a major psychoanalytic thinker presents a theory of personality through his explorations of one of humankind’s most basic attributes: sexuality. In addition, these writings reflect Adler’s theoretical dissatisfaction with what he felt were the deterministic beliefs of Sigmund Freud. And having presented them, he precipitated one of the most dramatic schisms in psychoanalytic psychology. |
