The subject must distinguish itself through opposition from the rational being, which it has assumed outside of itself. The subject has posited itself as one, which contains in itself the last ground of something that is in it, (for this is the condition of Egohood, or of Rationality generally;) but it has also posited a being outside of itself, as the last ground of this something in it. It is to have the power of distinguishing itself from this other being; and this is, under our presupposition, possible only, if the subject can distinguish in that given something how far the ground of this something lies in itself and how far it lies outside of itself.
