In this lecture examining the 1968 papal encyclical Humanae Vitae (Of Human Life), Ayn Rand discusses the meaning of the Catholic Church’s admonition against the use of contraception and the view of sex that it implies. She contrasts this religious perspective on sex with the Objectivist view, drawing out the relationships between love, sex, self-esteem and happiness.
A version of this talk was originally delivered live at the Ford Hall Forum on December 8, 1968. An edited version of this talk is available in The Voice of Reason: Essays in Objectivist Thought, a collection of essays by Rand and others. This recording is 56 minutes long.
