This book provides a clear and helpful overview of the thought of Emmanuel Levinas, one of the most significant and interesting philosophers of the late twentieth century. Michael L. Morgan presents an overall interpretation of Levinas's central principle that human existence is fundamentally ethical and that its ethical character is grounded in our face-to-face relationships with other people. He explores the religious, cultural, and political implications of this insight for modern Western culture and how it relates to our conception of selfhood and what it is to be a person, our understanding of the ground of moral values, our experience of time and the meaning of history, and our experience of religious concepts and discourse. The book includes an annotated list of recommended readings and a selected bibliography of books by and about Levinas. It will be an excellent introduction to Levinas for readers unfamiliar with his work, and even for those without a background in philosophy.
