 Human dàos of finding, choosing and following are capacities normally attributed to the  心 xīnheart-mind.  Zhuangzi recognizes its involvement in the construction process, but is skeptical of making it a kind of natural authority. It is, after all, only one of the natural organs involved—our daily reactions include being directed by our stomachs, our eyes, etc. Why, Zhuangzi wonders, should we think they need a single authority?  (HY 4/2/14–16)
