The Hundred Schools of Thought and Three Issues (I): The Cosmos

Laozi is said to be the first to have mentioned the concept of "cosmos" (yuzhou). We need not concern ourselves with the credibility of this account. However, this concept encompasses both time and space—"heaven, earth and the four corners are called yu, past and present are called zhou (Shi zi, xia)." Thus, it is possible that, at least during the Warring States period, thinkers were interested in such issues as these: What is the "heaven" above our heads like? What is the shape of the "earth" beneath our feet? Where does the source of time lie? At that distant point of origin, how were heaven, earth, and man formed?
