Note 14 — Front matter (continued 4)

Curiously enough, common speech here reverses our use of terms, because it looks at the matter from the practical instead of from the aesthetic point of view, regarding (very unpsychologically) the thought as the source of the image, not the image as the source of the thought. People call the words the expression of the thought: whereas for the observer, the hearer (and generally for the speaker, too), the words are the datum and the thought is their expressiveness — that which they suggest.
