We often make judgments about good and bad, right and wrong. Philosophical ethics is the critical examination of these and other concepts central to how we evaluate our own and each others’ behavior and choices.

This text examines some of the main threads of discussion on these topics that have developed over the last couple of millenia, mostly within the Western cultural tradition. It considers basic questions about moral and ethical judgment: Is there such a thing as something that is really right or really wrong independent of time, place and perspective? What is the relationship between religion and ethics? How can we reconcile self-interest and ethics? Is it ever acceptable to harm one person in order to help others? What do recent discussions in evolutionary biology or have to say about human moral systems? What is the relation between gender and ethics? The authors invite you to participate in their exploration of these and many other questions in philosophical ethics.

Where did the universe come from? Is life a result of chance, or design? If God is loving and all-powerful, why does evil still exist? Is religious belief just a byproduct of undirected evolutionary processes? Or did God make sure humans would evolve in such a way as to believe? Are philosophers closed-minded about religion? And why is so much of philosophy of religion about God—but not about gods?

Introduction to Philosophy: Philosophy of Religion introduces students to some of the major traditional arguments for and against the existence of God. It also includes discussions of some less well-known, but thought-provoking arguments for the existence of God, and one of the most important new challenges to religious belief from the Cognitive Science of Religion. An introductory chapter traces the deep interconnections between philosophy and religion throughout Western history, and a final chapter considers what place there is for non-Western and non-monotheistic religions within contemporary philosophy of religion.

Whatever your religious beliefs—or lack of beliefs—we think you will find many of the arguments in this book fascinating to think about, and useful starting points for deeper philosophical discussions.
