For the same reason, it cannot be asserted that the intuition, which is generally called artistic, differs from ordinary intuition as intensive intuition. This would be the case if it were to operate differently on the same matter. But since the artistic function is extended to wider fields, yet does not differ in method from ordinary intuition, the difference between them is not intensive but extensive. The intuition of the simplest popular love-song, which says the same thing, or very nearly, as any declaration of love that issues at every moment from the lips of thousands of ordinary men, may be intensively perfect in its poor simplicity, although it be extensively so much more limited than the complex intuition of a love-song by Leopardi. [Sidenote: _The difference is extensive and empirical._] The whole difference, then, is quantitative, and as such is indifferent to philosophy, _scientia qualitatum._ Certain men have a greater aptitude, a more frequent inclination fully to express certain complex states of the soul. These men are known in ordinary language as artists. Some very complicated and difficult expressions are not often achieved, and these are called works of art. The limits of the expression-intuitions that are called art, as opposed to those that are vulgarly called non-art, are empirical and impossible to define. If an epigram be art, why not a simple word? If a story, why not the news-jottings of the journalist? If a landscape, why not a topographical sketch? The teacher of philosophy in Molière's comedy was right: "whenever we speak, we create prose." But there will always be scholars like Monsieur Jourdain, astonished at having spoken prose for forty years without knowing it, who will have difficulty in persuading themselves that when they call their servant John to bring their slippers, they have spoken nothing less than--prose.
