Is there a human nature? Can knowledge of it help us live better lives? This book synthesises ancient and modern philosophical ideas and draws on scientific research to answer yes to both these questions. It develops an innovative normative theory on the basis of commonsensical, naturalistic, premisses; and it defends an Aristotelian normative theory -- whereby we should understand human goods as realisations or perfections of human nature -- against both traditional and emerging challenges to perfectionist ethics, including evolutionary biology and transhumanism. The result is a ground-breaking theory of 'natural perfectionism', which both returns perfectionistic ethics to its Aristotelian roots and shows how this is compatible with evolutionary biology and cognitive science. At a time when the very idea of human nature is viewed as something that can be readily transcended, this work recalls us to a realistic, sober and better-founded vision of it.

‘Tom Angier's book examines one of the most fundamental philosophical questions: what does it mean to live well? In clear, insightful and thought-provoking chapters, Angier defends ‘natural perfectionism'-the view that goodness consists in perfecting our nature. Ranging smoothly from Aristotle to Richard Dawkins, Angier maps the history of this idea, explores its implications and defends it against contemporary objections. The result is not merely a profound philosophical argument, but also a rich and cogent guide on how to lead a flourishing life.' ,
