Graham Priest, expert in non-classical logic, discusses the connection between logic and Buddhism. Topics include the influence of Buddhist patterns of reasoning, the exploration of Asian philosophies, the evolution from classical to non-classical logic, the emphasis on epistemology in ancient Buddhist logic, the principle of non-contradiction in Western philosophy, and Nagarjuna's Tetralemma in Buddhist philosophy.

Introduction to Buddhist Logic
Graham Priest, a distinguished professor of philosophy, shares his journey into studying Buddhist logic after initially being a mathematician. Meeting Jay Garfield, a friend well-versed in Eastern philosophies, notably Tibetan Buddhism, exposed Priest to a new realm of philosophical exploration beyond the Western tradition. Inspired by Garfield's translations and insights, Priest delved into Asian philosophy, realizing the vast richness and relevance of Eastern philosophical ideas.
Evolution of Logic: Non-Classical Logic
Classical logic, originating in the late 19th century with Gottlob Frege, became a cornerstone in Western philosophical thought. However, by the 1960s, concerns arose about its limitations, leading to the development of non-classical logics. These systems, such as paraconsistent logics, challenge traditional binary views of truth, exploring options beyond the simplistic true or false dichotomy. Modern logicians, like Graham Priest, have been incorporating these diverse logical frameworks to tackle complex philosophical issues.
Metaphysical Insights in Ancient Buddhism
Nagarjuna, a foundational figure in Madhyamaka philosophy, contested the notion of intrinsic nature or svabhava in traditional Buddhist metaphysics. By advocating the concept of emptiness or sunyata, Nagarjuna challenged the underlying assumptions of reality's inherent properties. This revolutionary perspective influenced the development of a four-valued or even five-valued logic, introducing contemporary scholars to profound metaphysical considerations within logical systems.
Synthesizing Ancient Wisdom and Contemporary Logic
The mutual exchange between ancient Buddhist philosophy and modern formal logic showcases a symbiotic relationship. While historical figures lacked the technical tools of modern logic, contemporary logicians can articulate and dissect their ideas with precision. By applying rigorous logical analysis to ancient texts like the Mulamadhyamaka Karika, scholars can elucidate the logical consequences and argumentative structures underlying complex metaphysical concepts, bridging the gap between philosophical traditions.
