  Zhang’s book contains an essay explicitly titled “Concerning The Relation of Philosophy and Medicine.” It is so central to the topic of this essay that it is worth quoting at length.  Zhang begins by remarking that recent (Chinese) medical journals accuse traditional Chinese philosophy of holding back the progress of medicine. He responds: “their authors do not understand the use of philosophy, nor do they understand that philosophy is actually the basis of medicine.” He quotes a passage from the Book of Songs (Shi jing) says: “he is intelligent and wise, and protects his own person” (Shi jing, “Zheng min” 烝民, Mao 260). The passage refers to a certain Zhong Shanfu 仲山甫, a virtuous minister of King Xuan of Zhou (r. 827–782 BCE). The point is that “protecting one’s person means not only protecting oneself from attach by thieves or robbers but also protecting one’s person from being beset by disease and illness. But, Zhang continues, the point of the quotation is that people must possess an inherent aptitude for intelligence and wisdom. They must also make a systematic study of wisdom and virtue, and only then can we protect our persons.
