NOBUHARA Yukihiro (Part-time lecturer) Professor, the University of Tokyo Graduate School of Arts and Sciences Come to think of it, our minds have many strange aspects. For a start, where does our mind exist? Is it in our body? But it seems that we cannot find it anywhere in our body, no matter where we look. So, where is it? Our mind is capable of thinking about events that happened many thousands of kilometers away. How on earth is that possible? Pleasure and sorrow come to mind, whether we like it or not. It is our own mind and why can't we control it? We will discuss various questions concerning our mind from a philosophical perspective. Moreover, we will also discuss the fact that our mind transcends our brain and body and expands out into the environment, while exploring consciousness, thought patterns, behavior, and perception of humans who live in the environment.
