Lu Jiuyuan (Chinese: 陸九淵; Pinyin: Lù Jiǔyuān), or Lu Xiangshan (陆象山; Lù Xiàngshān) (1139-1192) was a Chinese scholar who used Confucian terminology in a very Buddhist spirit.
Later movements of Neo-Confucianism revolted against Lu Jiuyuan's metaphysics that regarded moral conduct as a consequence of intuitive insights into the essence of reality. A later Neo-Confucian movement, the Lu Wang School, is named after Lu Jiuyuan and Wang Yangming.
In more recent times, his philosophy has been revived by Liang Sou-ming with the book The Civilization and Philosophy of the East and the West (1921).
