“That the truth is only realized in the form of system, that substance is essentially subject, is expressed in the idea which represents the Absolute as Spirit (Geist [which is also translated as ‘mind’) — the grandest conception of all, and one which is due who know spirit to be for itself, to be objective to itself; but in so far as spirit knows itself to be for itself, then this self-production, the pure notion, is the sphere and element in which its objectification takes effect, and where it gets its existential form. In this way it is in its existence aware of itself as an object in which its own self is reflected. Mind, which, when thus developed, knows itself to be mind, is science. Science is its realization, and the kingdom it sets up for itself in its own native element.

A self having knowledge purely of itself in the absolute antithesis of itself, this pure ether as such, is the very soil where science flourishes, is knowledge in universal form. The beginning of philosophy presupposes or demands from consciousness that it should feel at home in this element. But this element only attains its perfect meaning and acquires transparency through the process of gradually developing it. It is pure spirituality as the universal which assumes the shape of simple immediacy; and this simple element, existing with no apparent necessity for doing so. Let science be per se what it likes, in its relation to naïve immediate self-conscious life it presents the appearance of being a reversal of the latter; or, again, because naïve self-consciousness finds the principle of its reality in the certainty of itself, science bears the character of unreality, since consciousness ‘for itself’ is a state quite outside of science. [See Kuhn.] Science has for that reason to combine that other element of self-certainty with its own, or rather to show that the other element belongs to itself, and how it does so. When devoid of that sort of reality, science is merely the content of mind qua something implicit or potential (an sich); purpose, which at the start is no more than something internal; not spirit, but at first merely spiritual substance. This implicit moment (Ansich) has to find external expression, and become objective on its own account. This means nothing else than that this moment has to establish self-consciousness as one with itself.
