Fifth Corner of Four

Graham Priest presents an exploration of Buddhist metaphysics drawing on texts which include those of N�g�rjuna and D�gen. The development of Buddhist metaphysics is viewed through the lens of the catu.sko.ti. At its simplest and as it appears in the earliest texts this is a logical/ metaphysical principle which says that every claim is true false both or neither; but the principle itself evolves assuming new forms as the metaphysics develops. An important step in the evolution incorporates ineffability. Such things make no sense from the perspective of a logic which endorses the principles of excluded middle and non-contradiction which are standard fare in Western logic. However the book shows how one can make sense of them by applying the techniques of contemporary non-classical logic such as those of First Degree Entailment and Plurivalent Logic. An important issue that emerges as the book develops is the notion of non-duality and its transcendence. This allows many of the threads of the book to be drawn together at its end. All matters are explained in as far as possible in a way that is accessible to those with no knowledge of Buddhist philosophy or contemporary non-classical logic.<br>
