For Hegel, the world in its historical dimension is the dialectical revelation of consciousness to itself. In his curious idiom, the end of history comes when Spirit achieves awareness of its identity as Spirit, not, that is to say, alienated from itself by ignorance of its proper nature, but united to itself through itself: by recognizing that it is in this one instance of the same substance as its object, since consciousness of consciousness is consciousness.
