 Even, then, if we take the  心 xīnheart-mind as an authority, it’s not clear how it can help us deal with the role of judgments of greater and lesser wisdom and different ways of using  是非 shì-fēithis-not that.  Aren’t all the hearts involved in the evolving construction equally natural—the sages and the fools? (HY 4/2/21–22)
