History is wont to be divided into the history of man, the history or nature, and the mixed history of both the preceding. Without examining here the question of the solidity of this division, it is clear that artistic and literary history belongs in any case to the first, since it concerns a spiritual activity, that is to say, an activity proper to man. And since this activity is its subject, the absurdity of propounding the historical _problem of the origin of art_ becomes at once evident. We should note that by this formula many different things have in turn been included on many different occasions. _Origin_ has often meant _nature_ or _disposition_ of the artistic fact, and here was a real scientific or philosophic problem, the very problem, in fact, which our treatise has tried to solve. At other times, by origin has been understood the ideal genesis, the search for the reason of art, the deduction of the artistic fact from a first principle containing in itself both spirit and nature. This is also a philosophical problem, and it is complementary to the preceding, indeed it coincides with it, though it has sometimes been strangely interpreted and solved by means of an arbitrary and semi-fantastic metaphysic. But when it has been sought to discover further exactly in what way the artistic function was _historically formed_, this has resulted in the absurdity to which we have referred. If expression be the first form of consciousness, how can the historical origin be sought of what is _presupposed_ not to be a product of nature and of human history? How can we find the historical genesis of that which is a category, by means of which every historical genesis and fact are understood? The absurdity has arisen from the comparison with human institutions, which have, in fact, been formed in the course of history, and which have disappeared or may disappear in its course. There exists between the aesthetic fact and a human institution (such as monogamic marriage or the fief) a difference to some extent comparable with that between simple and compound bodies in chemistry. It is impossible to indicate the formation of the former, otherwise they would not be simple, and if this be discovered, they cease to be simple and become compound. The problem of the origin of art, historically understood, is only justified when it is proposed to seek, not for the formation of the function, but where and when art has appeared for the first time (appeared, that is to say, in a striking manner), at what point or in what region of the globe, and at what point or epoch of its history; when, that is to say, not the origin of art, but its most antique or primitive history, is the object of research. This problem forms one with that of the appearance of human civilization on the earth. Data for its solution are certainly wanting, but there yet remains the abstract possibility, and certainly attempts and hypotheses for its solution abound.
