On the Mindless Menace of Violence (1968)
Context: Yet we know what we must do. It is to achieve true justice among our fellow citizens. The question is not what programs we should seek to enact. The question is whether we can find in our own midst and in our own hearts that leadership of humane purpose that will recognize the terrible truths of our existence. We must admit the vanity of our false distinctions among men and learn to find our own advancement in the search for the advancement of others. We must admit in ourselves that our own children's future cannot be built on the misfortunes of others. We must recognize that this short life can neither be ennobled or enriched by hatred or revenge.
“Men do not know how to appreciate or measure luck except that of others. Their own never.”

And judge of others' feelings by our own!”
