Emmanuel Levinas was a significant contributor to the field of philosophy, phenomenology and religion. A key interpreter of Husserl, he stressed the importance of attitudes to other people in any philosophical system. For Levinas, to be a subject is to take responsibility for others as well as yourself and therefore responsibility for the one leads to justice for the many. He regarded ethics as the foundation for all other philosophy, but later admitted it could also be the foundation for theology. Michael Purcell outlines the basic themes of Levinas' thought and the ways in which they might be deployed in fundamental and practical theology, and the study of the phenomenon of religion. This book will be useful for undergraduate and graduate students in philosophy, theology and religious studies, as well as those with a theological background who are approaching Levinas for the first time.
