Abstract

This paper attempts to demonstrate the close similarity between the Chinese Hua-Yen school of Buddhism and Whitehead's system of process thought.  Much of the paper consists of a description of the essentials of Hua-Yen thought, since this system is not well-known in Western intellectual circles.  Parallels in important areas are discussed, such as those of Whitehead's "prehension" and Hua-Yen's interdependence.  The similarities in several areas are very close, as is the overall vision.  However, a major area of disagreement is that of Whitehead's insistence on asymmetrical causality as opposed to Hua-Yen's insistence that causality is multidirectional in space and time.  [Abstract from The Philosopher's Index]
