The notion of creation as a human faculty has traditionally been closely associated with the creative forces that act to give form to the universe, albeit as divine or immanent. Against the backdrop of the parallelism between the creative dynamics of the universe and human creativity, this chapter examines the sources of creation as elucidated by two Japanese authors: a philosopher and a physicist, who seek to understand our world according to the principles of modern physics. The chapter begins with an account of Albert Einstein’s visit to Japan in 1922, with special emphasis on his lecture at Kyoto University. The lecture was suggested by the philosopher Nishida Kitarō and was entitled “How did I create the theory of relativity?”. It then examines Nishida’s interest in Einstein’s thought process and his views on the common source of creativity in science, mathematics, and art. In addition, the ideas of the physicist Yukawa Hideki on creativity in science are presented. The chapter thereby directs attention to the roles of intuition and abstraction in human creativity and the co-creative interaction of self and world, as reflected in the writings of Nishida and Yukawa.
