Categorical condemnation is the hatred of the mob. It makes cowards brave. And there is nothing more fearful than a religious mob, a mob overflowing with righteousness – as at the crucifixion and before and since. This can happen only after we have made a categorical refusal to kindness: to heretics, foreigners, enemies or any other group different from ourselves.

There are moments when the heart is generous, and then it knows that for better or worse our lives are woven together here, one with one another and with the place and all the living things.

Supporters of the war are constantly asking those who oppose it: Why don't you deplore the wrongs and atrocities committed by the other side? The answer, so far as I am concerned, is that I do deplore the wrongs and atrocities committed by the other side. But I am responsible for the wrongs and atrocities committed by our side. And I am no longer able to participate in the assumption that atrocities committed by remote control are less objectionable than those committed at arm's length. I am most concerned with American obstacles to peace because I am an American.

Thinking is the most overrated human activity.

We have the world to live in on the condition that we will take good care of it. And to take good care of it we have to know it. And to know it and to be willing to take care of it, we have to love it.

If you don't know where you are, you don't know who you are.

You don't need to be told some things. You can sometimes tell more by a man's silence and the set of his head than by what he says.
