The only weapon that we have in our hands this evening is the weapon of protest. That's all.

Our only weapon is the truth.

The human race has only one really effective weapon and that is laughter.

We have no words. We don't have missiles, we don't have guns, we don't have tanks, we don't have the force of violence that wants to impose itself at any price. We have the strength of humility of those who receive the contempt of the world and of the powerful of the earth. Our only weapon - in the face of so much shame for humanity and so much suffering is what we have done today: to pray.

What I have come to find to be the greatest and most effective and successful weapon that we can use, known to man, to combat such adversaries as ignorance, racism, hatred, violence, is also the least expensive weapon, and the one that is the least used by Americans. That weapon is called communication.

An uprising of the reasonable is our only chance.

Ridicule is the only weapon which can be used against unintelligible propositions.

That's all they know. Shooting us people.

The ultimate weapon isn't this plague out in Vegas, or any new super H-bomb. The ultimate weapon has always existed. Every man, every woman, and every child owns it. It's the ability to say No and take the consequences.

In this war we have one weapon which our enemies cannot use against us, and that is the English language. Several other languages are spoken by larger numbers of people, but there is no other that has any claim to be a world-wide lingua franca.

Only the sword now carries any weight in the balance for the destiny of a nation.

Our integrity sells for so little, but it is all we really have. It is the very last inch of us, but within that inch, we are free.

The here and now is all we have, and if we play it right it's all we'll need.

Experiments are the only means of knowledge at our disposal. The rest is poetry, imagination.
