How do we live a good life? Grayling is a professional philosopher, and his latest book - subtitled 'The Search for The Best Way To Live' - is an attempt to focus upon the big question with which philosophy has been perennially preoccupied. Addressing a 'general reader' without condescension, Grayling depicts an ongoing conflict between 'secular' and 'transcendental' attempts to define the good life. Between, that is, a tradition based upon enlightened humanism and those opposing traditions which tend to manifest themselves in organised religions. Grayling is hardly a neutral observer of the debate. He is, rather, a passionate humanist, alert to the contemporary dangers of a variety of fundamentalisms. He tends, at points, to oversimplify the opposition. But this is an admirably clear and engaging book, as well as a learned one.
