Reasons and Persons

This landmark work of analytic philosophy challenges conventional views on rationality, morality, and personal identity. The author examines self defeating theories in ethics and explores how common assumptions about self interest can lead to irrational outcomes. The book investigates the nature of personal identity over time, arguing against the traditional belief in a distinct, unchanging ego. It also addresses population ethics, evaluating how moral principles apply to choices that affect the quality and quantity of future generations.
