My field of research is the history and philosophy of logic and mathematics in 17th century Europe. The main theme of my research is Leibniz's philosophy of mathematics. Especially, I focus on "the Labyrinth of Continuum" which is one of the central problems of Leibniz. In this context, I am also interested in the problem of continuum in 19th and 20th century (e.g. Brentano, Peirce, Cantor, Dedekind, Brouwer, H. Weyl). I am also studying Descartes' philosophy of mathematics, especially his early writings on mathematics and philosophy. My other research interest is the philosophy of concept formation. "How human beings create the ideas of abstract objects" is a traditional question since Plato and Aristotle, and this was a main topic of the 17th century philosophy. This includes the problems of abstraction, imagination and concepts. In this context, I am also interested in the philosophy of cognitive science.
