It is ideally superior to the sociological, comparative, prehistoric Aesthetic, which studies especially the art of savages, of children, of madmen, and of idiots. It is ideally superior also to that other Aesthetic, which has recourse to the conceptions of the genetic pleasure, of games, of illusion, of self-illusion, of association, of hereditary habit, of sympathy, of social efficiency, and so on. It is ideally superior to the attempts at logical explanation, which have not altogether ceased, even to-day, although they are somewhat rare, because, to tell the truth, fanaticism for Logic cannot be called the failing of our times. Finally, it is ideally superior to that Aesthetic which repeats with Kant, that the beautiful is finality without the idea of end, disinterested pleasure, necessary and universal, which is neither theoretical nor practical, but participates in both forms, or combines them in itself in an original and ineffable manner. But we should return to it, bringing with us the experience of a century of thought, the new facts collected, the new problems that have arisen, the new ideas that have matured. Thus we shall return again to the stage of mystical and romantic Aesthetic, but not to the personal and historical stage of its representatives. For in this matter, at least, they are certainly inferior to us: they lived a century ago and therefore inherited so much the less of the problems and of the results of thought which day by day mankind laboriously accumulates. They should return, but not to remain there; because, if a return to the romantic Aesthetic be advisable for the Kantians (while the idealists should not be advised to "return to Kant," that is to say, to a lower stage, which represents a recession), so those who come over, or already find themselves on the ground of mystical Aesthetic, should, on the other hand be advised to proceed yet further, in order to attain to a doctrine which represents a stage above it. This doctrine is that of the _pure intuition_ (or, what amounts to the same thing, of pure expression); a doctrine which also numbers representatives in all times, and which may be said to be immanent alike in all the discourses that are held and in all the judgments that are passed upon art, as in all the best criticism and artistic and literary history. This doctrine arises logically from the contradictions of mystical Aesthetic; I say, _logically_, because it contains in itself those contradictions and their solution; although _historically_ (and this point does not at present concern us) that critical process be not always comprehensible, explicit, and apparent.
