1850s, West India Emancipation (1857)
Context: Let me give you a word of the philosophy of reform. The whole history of the progress of human liberty shows that all concessions yet made to her august claims, have been born of earnest struggle. The conflict has been exciting, agitating, all-absorbing, and for the time being, putting all other tumults to silence. It must do this or it does nothing. If there is no struggle, there is no progress. Those who profess to favor freedom, and yet depreciate agitation, are men who want crops without plowing up the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its many waters. This struggle may be a moral one; or it may be a physical one; or it may be both moral and physical; but it must be a struggle. Power concedes nothing without a demand. It never did and it never will. Find out just what any people will quietly submit to, and you have found out the exact amount of injustice and wrong which will be imposed upon them; and these will continue till they are resisted with either words or blows, or with both. The limits of tyrants are prescribed by the endurance of those whom they oppress. [... ] Men might not get all they work for in this world, but they must certainly work for all they get. If we ever get free from the oppressions and wrongs heaped upon us, we must pay for their removal. We must do this by labor, by suffering, by sacrifice, and if needs be, by our lives and the lives of others.

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.
