Zhang Zai 张载 (北宋)
Zhang Zai (simplified Chinese:张载; traditional Chinese:張載; pinyin:Zhāng Zài; Wade–Giles:Chang Tsai) (1020–1077) was a Chinese Neo-Confucian moral philosopher and cosmologist. He is most known for laying out four ontological goals for intellectuals: To build up the manifestations of Heaven and Earth's spirit, to build up good life for the populace, to develop past sages' endangered scholarship, and to open up eternal peace.
