The final test of religious faith... is whether it will enable men to endure insecurity without complacency or despair, whether it can so interpret the ancient verities that they will not become mere escape hatches from responsibilities but instruments of insights into what civilization means.

Man has always been his own most vexing problem.

I think I should know how to educate a boy, but not a girl; I should be in danger of making her too learned.

We take, and must continue to take, morally hazardous actions to preserve our civilization. We must exercise our power. But we ought neither to believe that a nation is capable of perfect disinterestedness in its exercise, nor become complacent about a particular degree of interest and passion which corrupt the justice by which the exercise of power is legitimatized.

History is a realm in which human freedom and natural necessity are curiously intermingled.

There are evidently limits to the achievements of science; and there are irresolvable contradictions both between prosperity and virtue, and between happiness and ``the good life,'' which had not been anticipated in our philosophy.

The 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.
