Every experience of art [Footnote: Throughout this discussion, I use "experience of art," "aesthetic experience," and "beauty" with the same meaning.] contains, in the first place, the sensations which are the media of expression. In a painting, for example, there are colors; in a piece of music, tones; in a poem, word-sounds. To this material, secondly, are attached vague feelings. It is characteristic of aesthetic expressions, as we have observed, that their media, quite apart from anything that they may mean or represent, are expressive of moods--the colors of a painting have a _stimmung,_ so have tones and words, when rhythmically composed. The simplest aesthetic experiences, like the beauty of single musical tones or colors, are of no greater complexity; yet almost all works of art contain further elements; for as a rule the sensations do not exist for their own sakes alone, but possess a function, to represent things. The colors of a landscape painting are not only interesting to us as beautiful colors, but as symbols of a landscape; the words of a ballad charm and stimulate us not only through their music, but because of actions or events which they bring before the mind. This involves, psychologically speaking, that certain ideas--of trees and clouds in the painting, of men and their deeds in the poem--are associated to the sense elements and constitute their meaning. Such ideas or meanings are the third class of elements in the aesthetic experience. But these ideas, in their turn, also arouse emotions, only not of the indefinite sort which belong to the sense elements, but definite, like the emotions aroused by things and events in real life. For example, Rembrandt's "Man with the Gold Helmet" will not only move us in a vague way through the character and rhythm of its lines and colors, but will, in addition, stimulate sentiments of respect and veneration, similar to those that we should feel if the old warrior were himself before us. In such definite feelings we have, then, a fourth class of mental elements. A fifth class will make our list complete. It consists of images from the various sense departments--sight, hearing, taste, smell, temperature, movement--which arise in connection with the ideas or meanings, making them concrete and full. For example, some of the colors in a landscape painting will not only give us the idea that there is sunlight there, but will also arouse faint images of warmth, which will make the idea more vivid; other colors, representing the clouds, will produce faint sensations of softness; still others, representing flowers, may produce faint odors.
