Civilization 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.

We have, on the whole, more liberty and less equality than Russia has. Russia has less liberty and more equality. Whether democracy should be defined primarily in terms of liberty or equality is a source of unending debate.

Goodness, armed with power, is corrupted; and pure love without power is destroyed.

[There is] an increasing tendency among modern men to imagine themselves ethical because they have delegated their vices to larger and larger groups.

You can't say that religion or irreligion will give us a particular answer to the nuclear dilemma.

Toleration of people who differ in convictions and habits requires a residual awareness of the complexity of truth and the possibility of opposing view having some light on one or the other facet of a many-sided truth.

I think I have one answer, that is partly religious and partly secular; and that is to say, we ought to at least recognize that we and the Russians are in a common predicament. That would be religious in the sense, "Judge not lest you be judged."
