I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

All the forces in the world are not so powerful as an idea whose time has come.

The central defect of evil is not sin but the refusal to acknowledge sin.

Demoralize the enemy from within by surprise, terror, sabotage, assassination. This is the war of the future.

The only thing necessary for the triumph of evil is for good men to do nothing.

Everyone’s worried about stopping terrorism. Well, there’s really an easy way: Stop participating in it.

What is evil? - Whatever springs from weakness.

It is very queer that the unhappiness of the world is so often brought on by small men.

All the war-propaganda, all the screaming and lies and hatred, comes invariably from people who are not fighting.

When there's a person, there's a problem. When there's no person, there's no problem

A war between Europeans is a civil war.

Know yourself and you will win all battles.

When the enemy is relaxed, make them toil. When full, starve them. When settled, make them move.

You don't reason with intellectuals. You shoot them.

There is no safety for honest men except by believing all possible evil of evil men.

I object to violence because when it appears to do good, the good is only temporary; the evil it does is permanent

Theres class warfare, all right, but its my class, the rich class, thats making war, and were winning.

Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.

A person may cause evil to others not only by his actions but by his inaction, and in either case he is justly accountable to them for the injury.
