One: Being an Investigation into the Unity of Reality and of its Parts, including the Singular Object which is Nothingness;

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.
