“Without free speech no search for Truth is possible; without free speech no discovery of Truth is useful; without free speech progress is checked, and the nations no longer march forward towards the nobler life which the future holds for man. Better a thousandfold abuse of free speech than denial of free speech. The abuse dies in a day; the denial slays the life of the people and entombs the hope of the race.”

Address at Columbia University (1991)
Context: "Our lives teach us who we are." I have learned the hard way that when you permit anyone else's description of reality to supplant your own — and such descriptions have been raining down on me, from security advisers, governments, journalists, Archbishops, friends, enemies, mullahs — then you might as well be dead. Obviously, a rigid, blinkered, absolutist world view is the easiest to keep hold of, whereas the fluid, uncertain, metamorphic picture I've always carried about is rather more vulnerable. Yet I must cling with all my might to … my own soul; must hold on to its mischievous, iconoclastic, out-of-step clown-instincts, no matter how great the storm. And if that plunges me into contradiction and paradox, so be it; I've lived in that messy ocean all my life. I've fished in it for my art. This turbulent sea was the sea outside my bedroom window in Bombay. It is the sea by which I was born, and which I carry within me wherever I go.
"Free speech is a non-starter," says one of my Islamic extremist opponents. No, sir, it is not. Free speech is the whole thing, the whole ball game. Free speech is life itself.

Anarchism & American Traditions (1908)
Context: What has Anarchism to say to all this, this bankruptcy of republicanism, this modern empire that has grown up on the ruins of our early freedom? We say this, that the sin our fathers sinned was that they did not trust liberty wholly. They thought it possible to compromise between liberty and government, believing the latter to be "a necessary evil," and the moment the compromise was made, the whole misbegotten monster of our present tyranny began to grow. Instruments which are set up to safeguard rights become the very whip with which the free are struck.
Anarchism says, Make no laws whatever concerning speech, and speech will be free; so soon as you make a declaration on paper that speech shall be free, you will have a hundred lawyers proving that "freedom does not mean abuse, nor liberty license"; and they will define and define freedom out of existence. Let the guarantee of free speech be in every man's determination to use it, and we shall have no need of paper declarations. On the other hand, so long as the people do not care to exercise their freedom, those who wish to tyrannize will do so; for tyrants are active and ardent, and will devote themselves in the name of any number of gods, religious and otherwise, to put shackles upon sleeping men.
