Professor Masami Tateno is Professor at Department of Chinese Languages and Culture, Nihon University, Japan. He studies both Chinese philosophy (Daoism in particular) and Chinese/Japanese medicine, and has published many papers and several books on these topics, including “An Illustrated Interpretation of Laozi and Zhuangzi’s Philosophy” (2002) and “Chinese Medicine and Japanese Medicine” (2014). In this talk he discussed old Chinese expression “yiyi tongyuan” 医易同源, which means medicine and the philosophy of the I-Ching (Yijing) 易経came from intrinsically the same derivation. The I-Ching is not just a fortunetelling, but a “philosophy” which brimmed over with profound wisdom including some of medical essence. And not to mention medicine is also an acute subject to us even they are “traditional” ones. Prof. Tateno encouraged us to learn something new from the old ones, just as Confucius said (Lunyu, 2-11).
