Graham Priest presents an original exploration of philosophical questions concerning the one and the many. He covers a wide range of issues in metaphysics--including unity, identity, grounding, mereology, universals, being, intentionality, and nothingness--and deploys the techniques of paraconsistent logic in order to offer a radically new treatment of unity. Priest brings together traditions of Western and Asian thought that are usually kept separate in academic philosophy: he draws on ideas from Plato, Heidegger, and Nagarjuna, among other philosophers.About the Author: Graham Priest was educated at St. John's College, Cambridge, and the London School of Economics. He has held professorial positions at a number of universities in Australia, the UK, and the USA. He is well known for his work on non-classical logic, and its application to metaphysics and the history of philosophy.
