My 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.
Reinhold NiebuhrCivilization depends upon the vigorous pursuit of the highest values by people who are intelligent enough to know that their values are qualified by their interests and corrupted by their prejudices.
Reinhold NiebuhrNothing that is worth doing can be achieved in our lifetime; therefore we must be saved by hope. Nothing which is true or beautiful or good makes complete sense in any immediate context of history; therefore we must be saved by faith. Nothing we do, however virtuous, can be accomplished alone; therefore we must be saved by love. No virtuous act is quite as virtuous from the standpoint of our friend or foe as it is from our standpoint. Therefore we must be saved by the final form of love which is forgiveness.
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.
