Hegel represents history as the self-realization of spirit (Geist) or God. The fundamental scheme of his theory is as follows. Spirit is self-creative energy imbued with a drive to become fully conscious of itself as spirit. Nature is spirit in its self-objectification in space; history is spirit in its self-objectification as culture—the succession of world-dominant civilizations from the ancient Orient to modern Europe. Spirit actualizes its nature as self-conscious being by the process of knowing. Through the mind of man, philosophical man in particular, the world achieves consciousness of itself as spirit. This process involves the repeated overcoming of spirit's alienation (Entfremdung) from itself, which takes place when spirit as the knowing mind confronts a world that appears, albeit falsely, as objective, i.e. as other than spirit. Knowing is recognition, whereby spirit destroys the illusory otherness of the objective world and recognizes it as actually subjective or selbstisch. The process terminates at the stage of "absolute knowledge," when spirit is finally and fully "at home with itself in its otherness," having recognized the whole of creation as spirit—Hegelianism itself being the scientific form of this ultimate self-knowledge on spirit's part.
