The statements repeated so often, that art is not knowledge, that it does not tell the truth, that it does not belong to the world of theory, but to the world of feeling, and so forth, arise from the failure to realize exactly the theoretic character of simple intuition. This simple intuition is quite distinct from intellectual knowledge, as it is distinct from perception of the real; and the statements quoted above arise from the belief that only intellectual cognition is knowledge. We have seen that intuition is knowledge, free from concepts and more simple than the so-called perception of the real. Therefore art is knowledge, form; it does not belong to the world of feeling or to psychic matter. The reason why so many æstheticians have so often insisted that art is _appearance_ (_Schein_), is precisely that they have felt the necessity of distinguishing it from the more complex fact of perception, by maintaining its pure intuitiveness. And if for the same reason it has been claimed that art is _feeling_ the reason is the same. For if the concept as content of art, and historical reality as such, be excluded from the sphere of art, there remains no other content than reality apprehended in all its ingenuousness and immediacy in the vital impulse, in its _feeling,_ that is to say again, pure intuition. [Sidenote: _Criticism of the theory of æsthetic senses._] The theory of the _æsthetic senses_ has also arisen from the failure to establish, or from having lost to view, the character of expression as distinct from impression, of form as distinct from matter. This theory can be reduced to the error just indicated of wishing to find a passage from the qualities of the content to those of the form. To ask, in fact, what the æsthetic senses are, implies asking what sensible impressions are able to enter into æsthetic expressions, and which must of necessity do so. To this we must at once reply, that all impressions can enter into æsthetic expressions or formations, but that none are bound to do so of necessity. Dante raised to the dignity of form not only the "sweet colour of the oriental sapphire" (visual impressions), but also tactual or thermic impressions, such as the "dense air" and the "fresh rivulets" which "parch the more" the throat of the thirsty. The belief that a picture yields only visual impressions is a curious illusion. The bloom on a cheek, the warmth of a youthful body, the sweetness and freshness of a fruit, the edge of a sharp knife, are not these, too, impressions obtainable from a picture? Are they visual? What would a picture mean to an imaginary man, lacking all or many of his senses, who should in an instant acquire the organ of sight alone? The picture we are looking at and believe we see only with our eyes would seem to his eyes to be little more than an artist's paint-smeared palette.
