Here, then, we have a struggle against an enemy, to vanquish whom is really to suffer defeat, where victory in one consciousness is really lost in its opposite. Consciousness of life, of its existence and activity, is only an agonizing over this existence and activity, for therein it is conscious that its essence is only its opposite, is conscious only of its own nothingness. Raising itself out of this consciousness it goes over into the Unchangeable;
but this elevation is itself this same consciousness. It is, therefore, directly consciousness of the opposite, viz. of itself as a particular individual. The Unchangeable that enters into consciousness is through this very fact at the same time affected by individuality, and is only present with the latter; individuality, instead of.having been extinguished in the consciousness of the Unchangeable, only continues to arise” therefrom.
