"Bertrand Russell was one of the most famous and important philosophers of the twentieth century. In this account of his life and work A.C. Grayling introduces both Russell's contributions to logic and philosophy, and his wide-ranging views on education, politics, war, and sexual morality." "Russell is credited with being one of the founders of modern analytic philosophy, and also with playing an important part in the revolution in social attitudes witnessed throughout the world. This introduction gives a clear survey of Russell's achievements across their whole range."--Jacket.
