“The only weapon that we have in our hands this evening is the weapon of protest. That's all.”
Montgomery Bus Boycott speech, at Holt Street Baptist Church (5 December 1955) http://www.blackpast.org/?q=1955-martin-luther-king-jr-montgomery-bus-boycott
1950s
Source: A Testament of Hope: The Essential Writings and Speeches
Context: We are here, we are here this evening because we're tired now. And I want to say that we are not here advocating violence. We have never done that. I want it to be known throughout Montgomery and throughout this nation that we are Christian people. We believe in the Christian religion. We believe in the teachings of Jesus. The only weapon that we have in our hands this evening is the weapon of protest. That's all.

On potentials for misuse of nuclear power, p. 31
Portraits in Science interviews (1994)
Context: I, who had been in favour of nuclear energy for generating electricity … I suddenly realised that anybody who has a nuclear reactor can extract the plutonium from the reactor and make nuclear weapons, so that a country which has a nuclear reactor can, at any moment that it wants to, become a nuclear weapons power. And I, right from the beginning, have been terribly worried by the existence of nuclear weapons and very much against their use.

“Ridicule is the only weapon which can be used against unintelligible propositions.”
Letter to Francis Adrian Van der Kemp (30 July 1816), denouncing the doctrine of the Trinity.
1810s
Context: Ridicule is the only weapon which can be used against unintelligible propositions. Ideas must be distinct before reason can act upon them; and no man ever had a distinct idea of the trinity. It is the mere Abracadabra of the mountebanks calling themselves the priests of Jesus.
Essays on Education quoted in The New York Times (24 February 1959).
Variant ending: The source of better ideas is freedom. The surest path to wisdom is liberal education.
Context: Books won't stay banned. They won't burn. Ideas won't go to jail. In the long run of history, the censor and the inquisitor have always lost. The only sure weapon against bad ideas is better ideas. The source of better ideas is wisdom. The surest path to wisdom is a liberal education.
