We can now consider sentences which, as one might say, give an analysis of the impression we get, say, from a face. Take such a statement as, “The particular impression of this face is due to its small eyes and low forehead.” Here the words, “the particular impression”, may stand for a certain specification, e.g., “the stupid expression.” Or, on the other hand, they may mean, “what makes this expression a striking one” (i.e. an extraordinary one); or, “what strikes one about this face” (i.e., “what draws one's attention”). Or again, our sentence may mean, “If you change these features in the slightest the expression will change entirely (whereas you might change other features without changing the expression nearly so much)”. The form of this statement, however, mustn't mislead us into thinking that there is in every case a supplementing statement of the form, “First the expression was this, after the change it's that.” We can, of course, say, “Smith frowned, and his expression changed from this to that”, pointing, say, at two drawings of his face. – – (Compare with this the two statements: “He said these words”, and “His words said something”).
