Man is both strong and weak, both free and bound, both blind and far-seeing. He stands at the juncture of nature and spirit; and is involved in both freedom and necessity.
Reinhold NiebuhrAll social cooperation on a larger scale than the most intimate social group requires a measure of coercion.
Reinhold NiebuhrThe scientific observer of the realm of nature is in a sense naturally and inevitably disinterested. At least, nothing in the natural scene can arouse his bias. Furthermore, he stands completely outside of the natural so that his mind, whatever his limitations, approximates pure mind. The observer of the realm of history cannot be disinterested in the same way, for two reasons: first, he must look at history from some locus in history; secondly, he is to a certain degree engaged in its ideological conflicts.
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 NiebuhrWhen a church reaches up beyond its group and tries to enforce its standards upon a society that doesn't accept these standards, and perhaps for good reason, perhaps for bad reason, but anyway this is the problem we face in pluralistic society, that not necessarily every standard that every church tries to enforce upon the society is from the society's standpoint a good standard.
