"A precondition of rational behaviour is a basic understanding of the nature of oneself and the world. Any fusion of ethical and decision-theoretic rationality into a seamless package runs counter to some of our deepest intuitions. But 'You Are Them' makes a powerful case. Magnus Vinding's best book to date. Highly recommended." - David Pearce, co-founder of The Neuroethics Foundation, co-founder of World Transhumanist Association / Humanity+, and author of 'The Hedonistic Imperative' and 'The Anti-Speciesist Revolution'.
