For Schleiermacher, the sphere of Ethic included the whole Philosophy of the Spirit, in addition to morality. These are the two forms of human activity--that which, like Logic, is the same in all men, and is called activity of identity, and the activity of difference or individuality. There are activities which, like art, are internal or immanent and individual, and others which are external or practical. _The true work of art is the internal picture_. Measure is what differentiates the artist's portrayal of anger on the stage and the anger of a really angry man. Truth is not sought in poetry, or if it be sought there, it is truth of an altogether different kind. The truth of poetry lies in coherent presentation. Likeness to a model does not compose the merit of a picture. Not the smallest amount of knowledge comes from art, which expresses only the truth of a particular consciousness. Art has for its field the immediate consciousness of self, which must be carefully distinguished from the thought of the Ego. This last is the consciousness of identity in the diversity of moments as they pass; the immediate consciousness of self is the diversity itself of the moments, of which we should be aware, for life is nothing but the development of consciousness. In this field, art has sometimes been confused with two facts which accompany it there: these are sentient consciousness (that is, the feelings of pleasure and of pain) and religion. Schleiermacher here alludes to the sensualistic aestheticians of the eighteenth century, and to Hegel, who had almost identified art and religion. He refutes both points of view by pointing out that sentient pleasure and religious sentiment, however different they may be from other points of view, are yet both determined by an objective fact; while art, on the contrary, is free productivity. Dream is the best parallel and proof of this free productivity. All the essential elements of art are found in dream, which is the result of free thoughts and of sensible intuitions, consisting simply of images. But dream, as compared with art, is chaotic: when measure and order is established in dream, it becomes art. Thoughts and images are alike essential to art, and to both is necessary ponderation, reflexion, measure, and unity, because otherwise every image would be confused with every other image. Thus the moments of inspiration and of ponderation are both necessary to art.
