"This book challenges, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity. The author claims that we have a false view of our own nature; that it is often rational to act against our own best interests; that most of us have moral views that are directly self-defeating; and that, when we consider future generations the conclusions will often be disturbing. He concludes that non-religious moral philosophy is a young subject, with a promising but unpredictable future."
"Part 1 discusses ways in which theories about morality and rationality can be self-defeating and Part 2 the relations between what a single person can rationally want or do at different times, and what different people can rationally want or do. Parts 3 & 4 tackle personal identity and our obligations to future generations."
