What is certainty? Phenomenological reconsideration of “reality”

Phenomenology refers to the science of re-examining “experiences” that are usually unrecognized, in order to identify the “logic” lurking in phenomena that mostly go unnoticed because they are taken for granted. Today, concepts of “what is certain” and “what is reasonable” waver. Facing this situation, I work on redefining “reality” by radically questioning anew the concepts of “certainty” and “reason”. In doing so, I also expect the “ethics” which underlies reality to become conspicuous. When pursuing this issue, it is helpful to know of the works of modern Japanese philosophers, especially those of Kitaro Nishida and Hajime Tanabe. Physicists, mathematicians and neuroscientists of our time are also facing the fundamental question of “What is reality?”. I am stimulated by dialogues with them, which I would like to develop further in order to advance the phenomenological reinterpretation of “reality” and “consciousness”.

Professor Taguchi’s book The Problem of ‘Primal I’ in Edmund Husserl: An Inquiry into the Obvious ‘Proximity’ of the Self (Hosei University Press: 2010) is highly regarded as a culmination of research on Edmund Husserl's phenomenology. It was first published in German (the right-hand book), and then in Japanese four years later.

If you see things from an alien perspective, you will encounter an entirely different view.

Philosophy is an effort to disclose the preoccupied, seemingly obvious ideas that lurk in our daily lives. As in every field, epoch-making developments originate from new findings obtained by shifting everyone’s frame of reference or reexamining existing assumptions. This means that there is no one who has nothing to do with philosophy. Philosophical ideas definitely have the capability to change reality. I strongly believe that your experience gained through textual research, where you are drawn from your original standpoint into an unexpected world, is valuable not only in your research, but also in many aspects of your actual life.
