During his long life (1872-1970) Bertrand Russell was one of a handful of social thinkers, let alone internationally recognised philosophers, whose views on contemporary issues won for him a devoted and supportive audience on the one hand and a host of vituperative critics on the other. Russell's revolutionary writings frequently placed him in the centre of controversy with conservatives and all those who were unwilling to consider moral questions from a rational rather than an emotional stance. Al Seckel has compiled an exhaustive collection of Russell's very best and most thought-provoking essays on ethics, social morality, happiness, sex, adultery, marriage, and divorce. Often hidden in obscure journals, pamphlets, out-of-print periodicals, and hard-to-find books, the works assembled here comprise a comprehensive volume that is augmented by valuable section introductions and editor's comments. This volume also includes "Morality and Instinct" which is published here for the first time.
