Ethical Primate [PDF ebook] 
Humans, Freedom and Morality

In The Ethical Primate, Mary Midgley, ‘one of the sharpest critical pens in the West’ according to the Times Literary Supplement, addresses the fundamental question of human freedom. Scientists and philosophers have found it difficult to understand how each human-being can be a living part of the natural world and still be free. Midgley explores their responses to this seeming paradox and argues that our evolutionary origin explains both why and how human freedom and morality have come about.
