What follows if we reject belief in any kind of non-physical soul and instead embrace a physicalist picture of the world? A key implication, this book argues, is a naturalization of personal identity and ethics — a radically different way of thinking about ourself.

"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."
