I am not only a pacifist but a militant pacifist. I am willing to fight for peace. Nothing will end war unless the people themselves refuse to go to war.

With reasonable men, I will reason; with humane men I will plead; but to tyrants I will give no quarters, nor waste arguments where they will certainly be lost.

Silence is one of the hardest arguments to refute.

Never argue with stupid people, they will drag you down to their level and then beat you with experience.

How could man rejoice in victory and delight in the slaughter of men?

Give me the liberty to know, to utter, and to argue freely according to conscience, above all liberties.

No problem is so deep that it cannot be overcome, given the will of all parties, through discussion and negotiation rather than force and violence.

It isn’t enough to talk about peace. One must believe in it. And it isn’t enough to believe in it. One must work at it.

Lord, make me an instrument of Your peace. Where there is hatred let me sow love; where there is injury, pardon; where there is doubt, faith; where there is despair, hope; where there is darkness, light; and where there is sadness, joy.

If you compromise your own conscience, you will weaken your conscience. Soon your conscience will fail to guide you and you never will have real wealth based on peace of mind.

If the human race wishes to have a prolonged and indefinite period of material prosperity, they have only got to behave in a peaceful and helpful way toward one another.

He who has peace of mind disturbs neither himself nor another.
