More About Albert Ellis
By the early 1960s, Ellis became interested in human sexuality, relationships, and love. He worked on several research projects with known sex researcher Alfred Kinsey. Ellis published several books on sexuality including Sex Without Guilt, Sex Beliefs and Customs, and Homosexuality: Its Causes And Cure.
Later in life, in Sex and the Liberated Man, he reviewed his opinion on homosexuality to describe it as "not good nor bad," except from a religious point of view. In the 2001 edition of Sex Without Guilt, Ellis gives specific advice to homosexuals on how to enhance their sex life showing that he finally came to accept it as normal towards the end of his life.
Ellis' legacy is varied and deeply influential in today's psychological research.
