If there are no isolated phenomena in the world, if all phenomena are interconnected and interdependent, then it is clear that every social system and every social movement in history must be evaluated not from the standpoint of "eternal justice" or some other preconceived idea, as is not infrequently done by historians, but from the standpoint of the conditions which gave rise to that system or that social movement and with which they are connected.
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.
[Letter to his wife, Natalia Sedova]In addition to the happiness of being a fighter for the cause of socialism, fate gave me the happiness of being her husband. During the almost forty years of our life together she remained an inexhaustible source of love, magnanimity, and tenderness. She underwent great sufferings, especially in the last period of our lives. But I find some comfort in the fact that she also knew days of happiness.For forty-three years of my conscious life I have remained a revolutionist; for forty-two of them I have fought under the banner of Marxism. If I had to begin all over again I would of course try to avoid this or that mistake, but the main course of my life would remain unchanged. I shall die a proletarian revolutionist, a Marxist, a dialectical materialist, and, consequently, an irreconcilable atheist. My faith in the communist future of mankind is not less ardent, indeed it is firmer today, than it was in the days of my youth.Natasha has just come up to the window from the courtyard and opened it wider so that the air may enter more freely into my room. I can see the bright green strip of grass beneath the wall, and the clear blue sky above the wall, and sunlight everywhere. Life is beautiful. Let the future generations cleanse it of all evil, oppression and violence, and enjoy it to the full.
Ruthlessly, in despite of itself, the Enlightenment has extinguished any trace of its own self-consciousness. The only kind of thinking that is sufficiently hard to shatter myths is ultimately self-destructive.
The fact that labour is external to the worker, i.e., it does not belong to his intrinsic nature; that in his work, therefore he does not affirm himself but denies himself, does not feel content but unhappy, does not develop freely his physical and mental energy but mortifies his body and his mind. The worker therefore only feels himself outside his work, and in his work feels outside himself.
