 Later historians also noticed a number of striking resonances between Wang’s views and an earlier Neo-Confucian named Lu Xiangshan (1139–1193), who also spoke and wrote about a faculty of good knowledge and regarded the heartmind as a constituent of li (Pattern) (Ivanhoe 2009: 29–97). Because of the similarities between Lu and Wang, which in certain respect mirror similarities between Cheng Yi and Zhu Xi, it is customary among many scholars of Chinese philosophy to refer to two schools of thought in the Song-Ming period—the Cheng-Zhu school sometimes associated with the “Learning of Pattern” (Lixue 理學) and the Lu-Wang school often associated with the “Learning of Heartmind” (Xinxue 心學). This way of characterizing the two most influential poles of Neo-Confucian thought provides an historical lens through which many 20th and 21st century Confucian thinkers understand their own philosophical orientation and roots.
