“In the supreme struggle of social order against anarchy, we cannot deny to the champions of civilised society the moral latitude which is by common consent accorded to armed men fighting for their country against a foreign foe.”

As quoted in The Many Faces of Socialism Comparative Sociology and Politics (1983) by Paul Hollander, p. 224,
Context: I am not interested in dry economic socialism. We are fighting against misery, but we are also fighting against alienation. One of the fundamental objectives of Marxism is to remove interest, the factor of individual interest, and gain, from people's psychological motivations. Marx was preoccupied both with economic factors and with their repercussions on the spirit. If communism isn't interested in this too, it may be a method of distributing goods, but it will never be a revolutionary way of life.

Conclusion
The Ethics of Ambiguity (1947)
Context: A conquest of this kind is never finished; the contingency remains, and, so that he may assert his will, man is even obliged to stir up in the world the outrage he does not want. But this element of failure is a very condition of his life; one can never dream of eliminating it without immediately dreaming of death. This does not mean that one should consent to failure, but rather one must consent to struggle against it without respite.
