“Reverence for free speech is deeply embedded in American life, but speech cannot be protected unless those who acknowledge its value set aside their partisan differences for a moment and trust one another enough to say that the outrages against free speech must end.”

The Liberals' Mistake (1987)
Context: Liberals placed an unreasonable amount of faith in large institutions: unions, foundations, big government, large corporations, and universities. These institutions are based on principles that are antithetical to democracy. They are not democratic, they are hierarchical: Someone is at the top and everybody else is at the bottom. Their policies are not made democratically, they are made at the top. These institutions are also not egalitarian. They operate by administrative discretion and authority, not the rule of law: There is no legislature, no group lawmaking body.
The individual in the large organization does not have the kind of constitutional rights that an individual in the society at large has. There are no protections of autonomy and free speech. Employees can be fired for many reasons. We need to constitutionalize large organizations to protect the people within them, to ensure that they can be politically outspoken.

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.
