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.
