 Any shì-fēithis:right judgment concerning a dào may be either a 因 yīndependent shì, based on prior or enacted commitments, gestalts orientations, and inner processes or it may be an arbitrary posited (為 wèido:deem) shì. Dependency arises from past (chéngfixed) commitments to the dào structures through which we worked our way to our here-now. We always encounter such choices as we are already engaged in walking along some dào. Those past dào commitments bring us to a normative stance from which successive judgments of shì-fēi and 可 kěpermissible vs. not kě arise.  Zhuangzi’s pivotal illustration pairs 是 shìthis with 彼 bǐthat as near and far indexicals. His use of another indexical here signals his view that 是 shìthis:right used normatively as opposite to 非 fēinot-that:wrong is relative to a commitment index.
