reproduction, and because, in order to obtain this result, it is necessary to recall the conditions in which the stimulus first operated, we have also studied the function of historical erudition, directed toward the end of re-establishing our communication with the works of the past, and toward the creation of a base for aesthetic judgment (XVI.). We have closed our treatise by showing how the reproduction thus obtained is afterwards elaborated by the intellectual categories, that is to say, by an excursus on the method of literary and artistic history (XVII.). The aesthetic fact has thus been considered both in itself and in its relations with the other spiritual activities, with the feelings of pleasure and of pain, with the facts that are called physical, with memory, and with historical elaboration. It has passed from the position of _subject_ to that of _object_, that is to say, from the moment of _its birth_, until gradually it becomes changed for the spirit into _historical argument_. Our treatise may appear to be somewhat meagre, when compared with the great volumes usually consecrated to Aesthetic. But it will not seem so, when it is observed that these volumes, as regards nine-tenths of their contents, are full of matter which does not appertain to Aesthetic, such as definitions, either psychical or metaphysical, of pseudo-aesthetic concepts (of the sublime, the comic, the tragic, the humorous, etc.), or of the exposition of the supposed Zoology, Botany, and Mineralogy of Aesthetic, and of universal history judged from the aesthetic standpoint. The whole history of concrete art and literature has also been dragged into those Aesthetics and generally mangled; they contain judgments upon Homer and Dante, upon Ariosto and Shakespeare, upon Beethoven and Rossini, Michelangelo and Raphael. When all this has been deducted from them, our treatise will no longer be held to be too meagre, but, on the contrary, far more copious than ordinary treatises, for these either omit altogether, or hardly touch at all, the greater part of the difficult problems proper to Aesthetic, which we have felt it to be our duty to study.
