 Daoists, however, do not formulate these categories explicitly—partly because they may seem to overlap. A form of determinism, for example, would treat tian dao and great dao as identical—the laws of nature make only one world-history possible. Common sense indeterminism would regard many possible world histories as consistent with tian dao. In general, however, it is best to think of Great dao as simply the counterpart of Wittgenstein’s “All that is the case”—the extended actual space-time world. One of the insights of the Zhuangzi, not as clearly reflected in the Laozi, is that human dao is embedded in, part of and consistent with, both great dao and natural dao (tian dao).
