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 inacademic philosophy: he draws on ideas from Plato, Heidegger, and Nagarjuna, among other philosophers.
