Diane Perpich's book is one of the clearest and most accessible books on Levinas's thought available. She maps out nicely the central questions in Levinas scholarship, and is clear about where she stands. The last three chapters of the book are especially important. There Perpich tackles the difficult questions concerning normativity, the possibility of animal and environmental ethics, and the relevance of Levinas's philosophy for contemporary identity theory. This book is highly recommended to anyone with a serious interest in Levinas's philosophy and the current state of Levinas scholarship.
