Nishida Kitarō was the most significant and influential Japanese philosopher of the twentieth-century. His work is pathbreaking in several respects: it established in Japan the creative discipline of philosophy as practiced in Europe and the Americas; it enriched that discipline by infusing Anglo-European philosophy with Asian sources of thought; it provided a new basis for philosophical treatments of East Asian Buddhist thought; and it produced novel theories of self and world with rich implications for contemporary philosophizing. Nishida's work is also frustrating for its repetitive and often obscure style, exceedingly abstract formulations, and detailed but frequently dead-end investigations. Nishida once said of his work, “I have always been a miner of ore; I have never managed to refine it” (Nishida 1958, Preface)
