Even 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 NiebuhrHuman Beings are just good enough to make democracy possible...just bad enough to make it neccessary.
Reinhold NiebuhrFreedom is necessary for two reasons. It's necessary for the individual, because the individual, no matter how good the society is, every individual has hopes, fears, ambitions, creative urges, that transcend the purposes of his society. Therefore we have a long history of freedom, where people try to extricate themselves from tyranny for the sake of art, for the sake of science, for the sake of religion, for the sake of the conscience of the individual - this freedom is necessary for the individual.
Reinhold NiebuhrOur dreams of bringing the whole of human history under the control of the human will are ironically refuted by the fact that no group of idealists can easily move the pattern of history toward the desired goal of peace and justice. The recalcitrant forces in the historical drama have a power and persistence beyond our reckoning.
