This books demands the attention of us all, at every moment, and is a quiet masterpiece in recent continental thought. A work which Derrida has commented on, and built on so much in his earlier and later (affirmative) deconstrucion. This book is not simply a treatise on ethics, but one on metaphysics, logic, philosophy of religion, philosophy of mind, aesthetics, epistemology and indeed every thinkable area of ontological, onto-theological work that one can imagine. A treatise that makes us dramtically rethink everyone of these areas and so much more. Levinas will, in time, no doubt become regarded as one of the greats in the history of philosophy.
