The statements repeated so often, with others similar, 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, arise from the failure to realize exactly the theoretic character of the simple intuition. This simple intuition is quite distinct from intellectual knowledge, as it is distinct from the perception of the real. The belief that only the intellective is knowledge, or at the most also the perception of the real, also arises from the failure to grasp the theoretic character of the simple intuition. We have seen that intuition is knowledge, free of concepts and more simple than the so-called perception of the real. Since art is knowledge and form, it does not belong to the world of feeling and of psychic material. The reason why so many aestheticians have so often insisted that art is _appearance_ (_Schein_), is precisely because they have felt the necessity of distinguishing it from the more complex fact of perception by maintaining its pure intuitivity. For the same reason it has been claimed that art is _sentiment_. In fact, if the concept as content of art, and historical reality as such, be excluded, there remains no other content than reality apprehended in all its ingenuousness and immediateness in the vital effort, in _sentiment_, that is to say, pure intuition. [Sidenote] _Critique of theory of aesthetic senses._ The theory of the _aesthetic senses_ has also arisen from the failure to establish, or from having lost to view the character of the expression as distinct from the impression, of the form as distinct from the matter. As has just been pointed out, this reduces itself to the error of wishing to seek a passage from the quality of the content to that of the form. To ask, in fact, what the aesthetic senses may be, implies asking what sensible impressions may be able to enter into aesthetic expressions, and what must of necessity do so. To this we must at once reply, that all impressions can enter into aesthetic expressions or formations, but that none are bound to do so. Dante raised to the dignity of form not only the "sweet colour of the oriental sapphire" (visual impression), but also tactile or thermic impressions, such as the "thick air" and the "fresh rivulets" which "parch all the more" the throat of the thirsty. The belief that a picture yields only visual impressions is a curious illusion. The bloom of a cheek, the warmth of a youthful body, the sweetness and freshness of a fruit, the cutting of a sharpened blade, are not these, also, impressions that we have from a picture? Maybe they are visual? What would a picture be for a hypothetical man, deprived of all or many of his senses, who should in an instant acquire the sole organ of sight? The picture we are standing opposite and believe we see only with our eyes, would appear to his eyes as little more than the paint-smeared palette of a painter.
