Professor Shoryu Katsura, Professor Emeritus of Hiroshima and Ryukoku Universities, studied Buddhist philosophy at Kyoto University, where he received his B.A. and M.A., obtained his Ph.D. from the University of Toronto, and was granted the degree of D.Litt. by Kyoto University. He has edited Dharmakirti's Thought and Its Impact on Indian and Tibetan Philosophy (1999) and The Role of the Example (drstanta) in Classical Indian Logic (co-edited with Ernst Steinkellner, 2004), and published Nagarjuna's Middle Way (with Mark Siderits, 2013), Indian Logic (2021), a complete Japanese translation of the Gandavyuha-sutra (with Yuichi Kajiyama and others, 2021), and many articles. He is a recipient of the Japanese Association of Indian and Buddhist Studies Award (1977) and Nakamura Hajime Eastern Academic Award (2010).

Mark Siderits was trained in Asian and Western philosophy at the University of Hawaii and Yale University. He has taught both Asian and Western philosophy, for many years at Illinois State University, and most recently as Professor of philosophy at Seoul National University, from which he retired in 2012. He is the author or editor of five books and has published numerous articles on a wide variety of subjects in Indian Buddhist philosophy and comparative philosophy. Much of his work aims at building bridges between the classical Indian tradition and contemporary philosophy, by using insights from one tradition to cast light on problems arising in the other.
