“It would be no vindication of the right of speech to prove that certain gentlemen of great distinction, eminent for their learning and ability, are allowed to freely express their opinions on all subjects - including the subject of slavery. Such a vindication would need, itself, to be vindicated. It would add insult to injury. Not even an old-fashioned abolition meeting could vindicate that right in Boston just now. There can be no right of speech where any man, however lifted up, or however humble, however young, or however old, is overawed by force, and compelled to suppress his honest sentiments.”

1962, Cuban Missile Crisis speech
Context: The path we have chosen for the present is full of hazards, as all paths are; but it is one of the most consistent with our character and our courage as a nation and our commitments around the world. The cost of freedom is always high — but Americans have always paid it. And one path we shall never choose, and this is the path of surrender or submission. Our goal is not victory of might but the vindication of right — not peace at the expense of freedom, but both peace and freedom, here in this hemisphere and, we hope, around the world. God willing, that goal will be achieved. Thank you, and good night.

The trial of Charles B. Reynolds for blasphemy (1887)
Context: The question to be tried by you is whether a man has the right to express his honest thought; and for that reason there can be no case of greater importance submitted to a jury. And it may be well enough for me, at the outset, to admit that there could be no case in which I could take a greater — a deeper interest. For my part, I would not wish to live in a world where I could not express my honest opinions. Men who deny to others the right of speech are not fit to live with honest men.
I deny the right of any man, of any number of men, of any church, of any State, to put a padlock on the lips — to make the tongue a convict. I passionately deny the right of the Herod of authority to kill the children of the brain.
A man has a right to work with his hands, to plow the earth, to sow the seed, and that man has a right to reap the harvest. If we have not that right, then all are slaves except those who take these rights from their fellow-men.

"Edmund Burke, Anarchist" http://archive.lewrockwell.com/rothbard/rothbard11.html, first published as "A Note on Burke’s Vindication of Natural Society" in the Journal of the History of Ideas, 19, 1 (January 1958), p. 114.
Context: In 1756 Edmund Burke published his first work: Vindication of Natural Society. Curiously enough it has been almost completely ignored in the current Burke revival. This work contrasts sharply with Burke’s other writings, for it is hardly in keeping with the current image of the Father of the New Conservatism. A less conservative work could hardly be imagined; in fact, Burke’s Vindication was perhaps the first modern expression of rationalistic and individualistic anarchism. … "Anarchism" is an extreme term, but no other can adequately describe Burke’s thesis. Again and again, he emphatically denounces any and all government, and not just specific forms of government. … All government, Burke adds, is founded on one "grand error." It was observed that men sometimes commit violence against one another, and that it is therefore necessary to guard against such violence. As a result, men appoint governors among them. But who is to defend the people against the governors? … The anarchism of Burke’s Vindication is negative, rather than positive. It consists of an attack on the State rather than a positive blueprint of the type of society which Burke would regard as ideal. Consequently, both the communist and the individualist wings of anarchism have drawn sustenance from this work.

Context: What a stupendous, what an incomprehensible machine is man! Who can endure toil, famine, stripes, imprisonment and death itself in vindication of his own liberty, and the next moment, be deaf to all those motives whose powers supported him through his trial, and inflict on his fellow men a bondage, one hour of which is fraught with more misery than ages of that which he rose in rebellion to oppose.

And it is addressed, in particular, to speech critical of the government.
