But although history distinguishes and unifies, it never _divides_--that is to say, _separates_; and the _divisions of history_ which have been and are made do not originate otherwise than as the result of the same practical and abstractive process that we have seen break up the actuality of living history to collect and arrange the inert materials in the temporal scheme, rendered extrinsic. Histories already produced, and as such past, receive in this way titles (every thought is 'without title' in its actuality--that is to say, it has only itself for title), and each one is separated from the other, and all of them, thus separated, are classified under more or less general empirical conceptions, by means of classifications that more or less cross one another. We may admire copious lists of this sort in the books of methodologists, all of them proceeding, as is inevitable, according to one or the other of these general criteria: the criterion of the _quality_ of the objects (histories of religions, customs, ideas, institutions, etc., etc.), and that of _temporal-spatial_ arrangement (European, Asiatic, American, ancient, medieval, of modern times, of ancient Greece, of ancient Rome, of modern Greece, of the Rome of the Middle Ages, etc.); in conformity with the abstract procedure which, when dividing the concept, is led to posit on the one hand _abstract forms of the spirit_ (objects) and on the other _abstract intuitions_ (space and time). I shall not say that those titles and divisions are useless, nor even those tables, but shall limit myself to the' remark that the history of philosophy, of art, or of any other ideally distinct history, when understood as a definite book or discourse, becomes empirical for the reason already given, that true distinction is ideal, and a discourse or a book in its concreteness contains not only distinction but unity and totality, and to look upon either as incorporating only one side of the real is arbitrary. And I shall also observe that as there are histories of philosophy and of art in the empirical sense, so also nothing forbids our talking in the same sense of a general history, separate from special histories, indeed even of a history of progress and one of decadence, of good and evil, of truth and error.
