Graham Priest presents an exploration of Buddhist metaphysics, drawing on texts which include those of Nafarjuna and Dogen. The development of Buddhist metaphysics is viewed through the lens of the catuskoti. At its simplest, and as it appears in the earliest texts, this is alogical/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 logicwhich 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. Animportant 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 Buddhistphilosophy or contemporary non-classical logic. | The Fifth Corner of Four by Graham Priest, Hardcover | Indigo Chapters
