This book is an introduction to some of the main problems of philosophy--God, mind, freedom, knowledge, and ethics. The chapters may be read independently of one another. But when read in order, they tell a more or less continuous story. We begin with some reflections about the legacy of Socrates and then go on to the existence of God, which is perhaps the most basic philosophical question of all because our answer to it influences how we will answer all the others. This leads naturally to a discussion of death and the soul, and then to more modern ideas about the nature of persons. The later chapters are about whether it is possible for us to have objective knowledge in either science or ethics. James Rachels, from the Preface Problems from Philosophy and The Truth About the World: Basic Readings in Philosophy are at once James Rachels' newest contributions to philosophy and his last. In these two books, Rachels found a culminating expression for his love of philosophy.
