Before proceeding further, it may be well to draw certain consequences from what has been established and to add some explanations. [Sidenote: _Identity of art and intuitive knowledge._] We have frankly identified intuitive or expressive knowledge with the æsthetic or artistic fact, taking works of art as examples of intuitive knowledge and attributing to them the characteristics of intuition, and _vice versa._ But our identification is combated by a view held even by many philosophers, who consider art to be an intuition of an altogether special sort. "Let us admit" (they say) "that art is intuition; but intuition is not always art: artistic intuition is a distinct species differing from intuition in general by something _more_." [Sidenote: _No specific difference._] But no one has ever been able to indicate of what this something more consists. It has sometimes been thought that art is not a simple intuition, but an intuition of an intuition, in the same way as the concept of science has been defined, not as the ordinary concept, but as the concept of a concept. Thus man would attain to art by objectifying, not his sensations, as happens with ordinary intuition, but intuition itself. But this process of raising to a second power does not exist; and the comparison of it with the ordinary and scientific concept does not prove what is intended, for the good reason that it is not true that the scientific concept is the concept of a concept. If this comparison proves anything, it proves just the opposite. The ordinary concept, if it be really a concept and not a simple representation, is a perfect concept, however poor and limited. Science substitutes concepts for representations; for those concepts that are poor and limited it substitutes others, larger and more comprehensive; it is ever discovering new relations. But its method does not differ from that by which is formed the smallest universal in the brain of the humblest of men. What is generally called _par excellence_ art, collects intuitions that are wider and more complex than those which we generally experience, but these intuitions are always of sensations and impressions. Art is expression of impressions, not expression of expression. [Sidenote: _No difference of intensity._]
