This book explores the Confucian-Christian dialogue in Korea through a comparative study of the cosmologies of Alfred North Whitehead (1861-1947), the founder of process philosophy, and Yi Yulgok (1536-1584), the great scholar of Korean Neo-Confucianism. Despite coming from different philosophical traditions, Yulgok and Whitehead had similar perspectives on the universe. This study argues that Whitehead's theory of eternal object-actual entity has affinities with Yulgok's theory of principle-material force and offer insights into encouraging interreligious spirituality in Korea.
