Rene Descartes(1569-1650),the 'father' of modern philosophy,is without doubt one of the greatest thinkers in history:his genius lies at the core of our contemporary intellectual identity.Breaking with the conventions of his own time and suffering persecution by the Church as a consequence,Descartes in his writings-most of which are philosophical classics-attempted to answer the central questions surrounding the self,God,free-will and knowledge,using the science of thought as opposed to received wisdom based on the tenets of faith.This edition,the most comprehensive one-volume selection of Descartes' works available in English,includes his great essay,Discourse on Method.

Marriage and Morals is a compelling cross-cultural examination of individual, familial and societal attitudes towards sex and marriage. By exploring the codes by which we live our sexual lives and conventional morality, Russell daringly sets out a new morality, shaped and influenced by dramatic changes in society such as the emancipation of women and the wide-spread use of contraceptives. From the origin of marriage to the influence of religion, Russell explores the changing role of marriage and codes of sexual ethics. The influence of this great work has turned it into a worthy classic. 作者简介： Bertrand Russell (1872-1970) was born in England and educated at Trinity College, Cambridge.
