西田 (Nishida) refers to Nishida Kitarō, a prominent Japanese philosopher known for his contributions to Western and Eastern philosophy. Born in 1870, he is best known for developing the concept of "pure experience," which emphasizes the importance of direct experience in understanding reality. His work has influenced various fields, including aesthetics, ethics, and metaphysics. Nishida founded the Kyoto School, a group of philosophers who sought to integrate Western philosophical ideas with Eastern thought, particularly Buddhism. His writings, such as "An Inquiry into the Good," explore the relationship between self and the world, making significant impacts on modern philosophy in Japan and beyond.
