Butler, Judith.Subjects of Desire. New York: Columbia University Press, 1987. Print.
… Hegel here characterizes the negativity of desire as the final, fully realized form of self-consciousness. To understand this correctly, we must not assume that negation is nothingness; on the contrary, as a differentiating relation that mediates the terms that initially counter each other, negation, understood in the sense of Aufhebung, cancels, preserves, and transcends the apparent differences it interrelates. As the final realization of self-consciousness, negation is a principle of absolute mediation, an infinitely capable subject that is its interrelations with all apparently different phenomena. 41
