A Scottish Play

Sparknotes interprets There’s no art, To find the mind’s construction in the face as meaning 'There’s no way to read a man’s mind by looking at his face.'
If that's a fair interpretation, then--while it's a good and deep thought--it's not really my meaning, in calling attention the importance of face in our own culture.  I'm saying that social status is immensely important in our own social setup; a great deal of effort and mental bandwidth goes into 'fitting in' and maintenance of one's social role and position.  The idea that Chinese individual conduct is dictated-to in a way entirely unknown within American society represents a basic misunderstanding of American society, in other words.
