identical understanding of things. Two individuals who possess this faculty and belong to the same social circle or the same family apprehend an expression of feeling precisely to the same point, namely, the point beyond which such expression becomes mere phrasing. Thus they apprehend precisely where commendation ends and irony begins, where attraction ends and pretence begins, in a manner which would be impossible for persons possessed of a different order of apprehension. Persons possessed of identical apprehension view objects in an identically ludicrous, beautiful, or repellent light; and in order to facilitate such identical apprehension between members of the same social circle or family, they usually establish a language, turns of speech, or terms to define such shades of apprehension as exist for them alone.
