Lu Jiuyuan 陸九淵 (1139–1193), courtesy name Zijing 子靜, literary name Xiangshan 象山, was born in the town of Jinxi 金谿 in Jiangxi province. He was the youngest of six brothers, two of whom, fourth brother Jiushao 九紹 (fl. twelfth century), courtesy name Zimei 子美, literary name Suoshan 梭山, and fifth brother Jiuling 九齡 (1132–1180), courtesy name Zishou 子壽, literary name Fuzhai 復齋, were impressive philosophers in their own right. As we shall discuss below, Jiuling was present at and participated in the extended discussion and exchange Jiuyuan had with Zhu Xi 朱熹 (1130–1200) at Goose Lake Temple (E hu si 鵝湖寺) in 1175; Jiushao initiated an important and extended scholarly debate with Zhu over the interpretation of a number of metaphysical issues central to daoxue philosophy at the time.
