Now 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 NiebuhrThe whole art of politics consists in directing rationally the irrationalities of men.
Reinhold NiebuhrIt is the evil in man that makes democracy necessary, and man's belief in justice that makes democracy possible.
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 NiebuhrOur dreams of a pure virtue are dissolved in a situation in which it is possible to exercise the virtue of responsibility toward a community of nations only by courting the prospective guilt of the atomic bomb.
Reinhold NiebuhrMy personal attitude toward atheists is the same attitude that I have toward Christians, and would be governed by a very orthodox text: "By their fruits shall ye know them." I wouldn't judge a man by the presuppositions of his life, but only by the fruits of his life. And the fruits - the relevant fruits - are, I'd say, a sense of charity, a sense of proportion, a sense of justice. And whether the man is an atheist or a Christian, I would judge him by his fruits, and I have therefore many agnostic friends.
