But it is equally just and advantageous to maintain the opposite thesis: that _nothing exists but general history._ In this way is refuted the false notion of the speciality of histories, understood as a juxtaposition of specialities. This fallacy is correctly noted by the critics in all histories which expose the various orders of facts one after the other as so many strata and (to employ the critics' word) compartments or little boxes, containing political history, industrial and commercial history, history of customs, religious history, history of literature and of art, and so on, under so many separate headings. These divisions are merely literary, they may possess some utility as such, but in the case under consideration they do not fulfil merely a literary function, but attempt that of historical understanding, and thereby give evidence of their defect, in thus presenting these histories as without relation between one another, not dialecticized, but aggregated. It is quite clear that _history_ remains to be written after the writing of those _histories_ in this disjointed manner. Abstract distinction and abstract unity are both equally misunderstandings of concrete distinction and concrete unity, which is relation. And when the relation is not broken and history is thought in the concrete, it is seen that to think one aspect is to think all the others at the same time. Thus it is impossible to understand completely the doctrine, say, of a philosopher, without having to some extent recourse to the personality of the man himself, and, by distinguishing the philosopher from the man, at the same time qualifying not only the philosopher but the man, and uniting these two distinct characteristics as a relation of life and philosophy. The same is to be said of the distinction between the philosopher as philosopher and as orator or artist, as subject to his private passions or as rising to the execution of his duty, and so on. This means that we cannot think the history of philosophy save as at the same time social, political, literary, religious, and ethical history, and so on. This is the source of the illusion that one in particular of these histories is the whole of them, or that that one from which a start is made, and which answers to the predilections and to the competence of the writer, is the foundation of all the others. It also explains why it is sometimes said that the 'history of philosophy' is also the 'philosophy of history,' or that 'social history' is the true 'history of philosophy,' and so on. A history of philosophy thoroughly thought out is truly the whole of history (and in like manner a history of literature or of any other form of the spirit), not because it annuls the other in itself, but because all the others are present in it. Hence the demand that historians shall acquire universal minds and a doctrine that shall also be in a way universal, and the hatred of specialist historians,
