What is the nature of value and how can we have knowledge of it? Is something valuable because we desire it or do we desire it because it is valuable? These are the fundamental questions addressed and answered in this book. Graham Oddie argues that there are mind-independent irreducible facts about value, which are causally efficacious, and that we have knowledge of value by experiential acquaintance. Anyone working in ethics and metaphysics will find Value, Reality, and Desire a highly original and rewarding contribution.
