Internet users won't know what they've got till it's gone.
If we don't believe in freedom of expression for people we despise, we don't believe in it at all.
When I was asked to make this address I wondered what I had to say to you boys who are graduating. And I think I have one thing to say. If you wish to be useful, never take a course that will silence you. Refuse to learn anything that implies collusion, whether it be a clerkship or a curacy, a legal fee or a post in a university. Retain the power of speech no matter what other power you may lose. If you can take this course, and in so far as you take it, you will bless this country. In so far as you depart from this course, you become dampers, mutes, and hooded executioners.
As a practical matter, a mere failure to speak out upon occassions where no statement is asked or expected from you, and when the utterance of an uncalled for suspicion is odious, will often hold you to a concurrence in palpable iniquity. Try to raise a voice that will be heard from here to Albany and watch what comes forward to shut off the sound. It is not a German sergeant, nor a Russian officer of the precinct. It is a note from a friend of your father's, offering you a place at his office. This is your warning from the secret police. Why, if you any of young gentleman have a mind to make himself heard a mile off, you must make a bonfire of your reputations, and a close enemy of most men who would wish you well.
I have seen ten years of young men who rush out into the world with their messages, and when they find how deaf the world is, they think they must save their strength and wait. They believe that after a while they will be able to get up on some little eminence from which they can make themselves heard. "In a few years," reasons one of them, "I shall have gained a standing, and then I shall use my powers for good." Next year comes and with it a strange discovery. The man has lost his horizon of thought, his ambition has evaporated; he has nothing to say. I give you this one rule of conduct. Do what you will, but speak out always. Be shunned, be hated, be ridiculed, be scared, be in doubt, but don't be gagged. The time of trial is always. Now is the appointed time.Commencement Address to the Graduating Class of Hobart College, 1900
You can have a lot of political 'change' in the United States, but will it really change that much? Will it change the amount of money in someone’s bank account? Will it change contracts? Will it void contracts that already exist? And contracts on contracts? And contracts on contracts on contracts? Not really.
So I say that free speech in many Western places is free not as a result of liberal circumstances but rather as a result of such intense fiscalization that it doesn’t matter what you say. The dominant elite doesn’t have to be scared of what people think, because a change in political view is not going to change whether they own their company or not; it is not going to change whether they own a piece of land or not. But China is still a political society, although it is rapidly heading toward a fiscalized society. And other societies, like Egypt, are still heavily politicized. Their rulers really do need to be concerned about what people think, so they expend proportionate efforts on controlling freedom of speech.
If all mankind minus one were of one opinion, mankind would be no more justified in silencing that one person than he, if he had the power, would be justified in silencing mankind.
Whoever would overthrow the liberty of a nation must begin by subduing the freeness of speech.
(or even "better", make undesired thoughts unthinkable)
Take away freedom of speech, and the creative faculties dry up.
