Although Ming Confucian Ch'en Pai-sha was the only cantonese who was enshrined in the Confucian Temple, his thought has not drawn enough attention from scholars in the field of Sung Ming Neo-Confucianism. This oversight, perhaps, owes to Chen's special academic style, that emphasized acquiring insights for oneself (tzu-te) rather than theorizing the complexities of book-learning. This indeed made the theme and spirit of his thought more difficult to understand adequately. However, in The Philosophical Records of Ming Confucianists (Ming-ju hsueh-an), Huang Tsung-hsi said, "With Ch'en Pai-sha, Ming learning started to become precise and subtle." So we should not neglect Ch'en's contribution and the significance of his teachings, as a forerunner in the transformation of Confucianism in the mid-Ming. This article aims to get a comprehensive and appropriate understanding of Ch'en's philosophy by analyzing its major concepts such as chueh-wu (enlightenment), hsu-ching (vacuity and tranquillity), ching-tso (quiet-sitting) and tzu-jan (the natural, or spontaneity). Moreover, this inquiry tries to bring further clarification about the academic relationships between Ch'en, Lu Hsiang-shan and Wang Yang-ming, as well as to reexamine various criticisms of Ch'en's thought.
