Quantum Spacetime: Echoes of Basho
摘要
I will discuss how the concept of basho (場所 ), introduced by Nishida Kitarō nearly a century ago, can provide an interesting insight to understand the concept of a point in modern quantum gravity. A quantum spacetime, necessary for the quantization of gravity, requires a complete rethinking of geometry, starting from the primitive concepts, such as that of a point. I argue that the local vision of what becomes of classical points in quantum gravity, and in particular in noncommutative geometry, shows several similarities with Nishida’s basho.
