In a war of ideas it is people who get killed.

For as long as a time as we can see into the future, we shall be living between war and peace, between a war that cannot be fought and a peace that cannot be achieved. The great issues which divide the world cannot be decided by a war that could be won, and they cannot be settled by a treaty that can be negotiated... the power which used to deal with the division and conflicts of the past, namely, organized war, has become an impossible instrument to use.

To those to whom war is necessary it is just.

The perfect condition of slavery... is nothing else but the state of war continued between a lawful conqueror and a captive, for if once compact enter between them, and make an agreement for a limited power on the one side, and obedience on the other, the state of war and slavery ceases as long as the compact endures; for, as has been said, no man can by agreement pass over to another that which hath not in himself - a power over his own life.

War is no more inevitable than the plague is inevitable. War is no more a part of human nature than the burning of witches is a human act.

The wounds of civil war are deepest.

I know war as few other men now living know it, and nothing to me is more revolting. I have long advocated its complete abolition, as its very destructiveness on both friend and foe has rendered it useless as a method for settling international disputes.

The great question is: can war be outlawed? If so, it would mark the greatest advance in civilization since the Sermon on the Mount.

War’s very object is victory, not prolonged indecision. In war there is no substitute for victory.

Every one may begin a war at his pleasure, but cannot so finish it. A prince, therefore, before engaging in any enterprise, should well measure his strength, and govern himself accordingly.

He who makes war his profession cannot be otherwise than vicious. War makes thieves, and peace brings them to the gallows.

One believes in the coming of war if one does not sufficiently abhor it.

We are advocates of the abolition of war, we do not want war; but war can only be abolished through war, and in order to get rid of the gun it is necessary to take up the gun.

Politics is war without bloodshed while war is politics with bloodshed.

Violence and war never solve problems; they only make them more acute. They create new dilemmas and new paradoxes.

I believe that religion, generally speaking, has been a curse to mankind-that its modest and greatly overestimated services on the ethical side have been more than overcome by the damage it has done to clear and honest thinking. I believe that all government is evil, in that all government must necessarily make war upon liberty.

The immediate cause of World War III is the preparation of it.

There will be no veterans of World War III.

A good war makes sacred any cause.

Against war it may be said that it makes the victor stupid and the vanquished revengeful.
