Since its original publication, Taking Darwin Seriously has established itself as one of the most important works of evolutionary naturalism since Charles Darwin's Origin of Species over a century ago. Applying evolutionary biology to philosophical problems of epistemology and ethics, it definitively establishes a naturalistic approach to our understanding of life's major problems. Updated with a new preface and a final chapter that addresses the most recent developments in and popular attacks on contemporary evolution, this is an essential work for those interested in the implications of modern Darwinism - especially human sociobiology - for questions in the theory of knowledge and of moral behaviour and thought. Written in a style accessible to both the professional and the general reader, Taking Darwin Seriously is intended as a direct challenge to all who would push creationism as a credible alternative to scientific evolution in public schools, universities, and as a general theory for public consumption.
