Short of nuclear war itself, population growth is the gravest issue the world faces. If we do not act, the problem will be solved by famine, riots, insurrection and war.

It is true that at the time [1962] we had a strategic nuclear force of approximately five thousand warheads compared to the Soviet's three hundred.

I don't object to its being called "McNamara's war." I think it is a very important war and I am pleased to be identified with it and do whatever I can to win it.

One solitary God-centered, God-intoxicated man can do more to keep God's love alive and His presence felt in the world than a thousand half-hearted, talkative busy men living frightened, fragmented lives of quiet desperation.

I want to say, and this is very important: at the end we lucked out. It was luck that prevented nuclear war. We came that close to nuclear war at the end. Rational individuals: Kennedy was rational; Khrushchev was rational; Castro was rational. Rational individuals came that close to total destruction of their societies. And that danger exists today.

Action should be founded on contemplation, and those of us who act don't put enough time, don't give enough emphasis, to contemplation.

I like to run down to the beach and have a little swim in the nude in the morning.
