[There is] an increasing tendency among modern men to imagine themselves ethical because they have delegated their vices to larger and larger groups.
Reinhold NiebuhrLiberalism makes this mistake in regard to private property and Marxism makes it in regard to socialized property... The Marxist illusion is partly derived from a romantic conception of human nature... It assumes that the socialization of property will eliminate human egotism... The development of a managerial class in Russia, combing economic with political power, is an historic refutation of the Marxist theory.
Reinhold NiebuhrNow we're living in a nuclear age, and the science that was supposed to be automatically for human welfare has become a nuclear - a science that gives us nuclear weapons. This is the ironic character of human history, and of human existence, which I can only explain, if I say so, in Biblical terms. Now I don't mean by this reason that I will accept every interpretation of Christianity that's derived from the Bible as many people wouldn't accept my interpretation. But that's what it means for me.
Reinhold NiebuhrEven as rigorous a determinist as Karl Marx, who at times described the social behaviour of the bourgeoisie in terms which suggested a problem in social physics, could subject it at other times to a withering scorn which only the presupposition of moral responsibility could justify.
Reinhold NiebuhrThe separation of church and state is necessary partly because if religion is good then the state shouldn't interfere with the religious vision or with the religious prophet. There must be a realm of truth beyond political competence, that's why there must be a separation of churches, but if religion is bad and a bad religion is one that gives an ultimate sanctity to some particular cause. Then religion mustn't interfere with the state - so one of the basic Democratic principles as we know it in America is the separation of church and state.
