This book challenges, with several powerful arguments, some of our deepest belie
fs 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 o
ur own best interests; that most of us have moral views that are directly self-d
efeating; and that, when we consider future generations the conclusions will oft
en be disturbing. He concludes that moral non-religious moral philosophy is a yo
ung subject, with a promising but unpredictable future.
