Thus we see that Philosophy is system in development; the history of Philosophy is the same; and this is the main point to be noted and the first principle to be dealt with in this treatise on that history. In order to make this evident, the difference in respect to the possible modes of manifestation must first be pointed out. That is to say, the progression of the various stages in the advance of Thought may occur with the consciousness of necessity, in which case each in succession deduces itself, and this form and this determination can alone emerge. Or else it may come about without this consciousness as does a natural and apparently accidental process, so that while inwardly, indeed, the Notion brings about its result consistently, this consistency is not made manifest. This is so in nature; in the various stages of the development of twigs, leaves, blossom and fruit, each proceeds for itself, but the inward Idea is the directing and determining force which governs the progression. This is also so with the child whose bodily powers, and above all whose intellectual activities, make their appearance one after the other, simply and naturally, so that those parents who form such an experience for the first time, marvel whence all that is now showing itself from within, comes from; for the whole of these manifestations merely have the form of a succession in time. The one kind of progression which represents the deduction of the forms, the necessity thought out and recognized, of the determinations, is the business of Philosophy; and because it is the pure Idea which is in question and not yet its mere particularized form as Nature and as Mind, that representation is, in the main, the business of logical Philosophy. But the other method, which represents the part played by the history of Philosophy, shows the different stages and moments in development in time, in manner of occurrence, in particular places, in particular people or political circumstances, the complications arising thus, and, in short, it shows us the empirical form. This point of view is the only one worthy of this science. From the very nature of the subject it is inherently the true one, and through the study of this history it will be made manifest that it actually shows and proves itself so.
