“I hate Communism because it is the negation of liberty and because humanity is for me unthinkable without liberty.”

Anarchist Manifesto (1850)
Context: Indeed:
Who says anarchy, says negation of government;
Who says negation of government, says affirmation of the people;
Who says affirmation of the people, says individual liberty;
Who says individual liberty, says sovereignty of each;
Who says sovereignty of each, says equality;
Who says equality, says solidarity or fraternity;
Who says fraternity, says social order;
By contrast:
Who says government, says negation of the people;
Who says negation of the people, says affirmation of political authority;
Who says affirmation of political authority, says individual dependency;
Who says individual dependency, says class supremacy;
Who says class supremacy, says inequality;
Who says inequality, says antagonism;
Who says antagonism, says civil war;
From which it follows that who says government, says civil war.

The trial of Charles B. Reynolds for blasphemy (1887)
Context: Liberty is the condition of progress. Without Liberty, there remains only barbarism. Without Liberty, there can be no civilization.
If another man has not the right to think, you have not even the right to think that he thinks wrong. If every man has not the right to think, the people of New Jersey had no right to make a statute, or to adopt a constitution — no jury has the right to render a verdict, and no court to pass its sentence.
In other words, without liberty of thought, no human being has the right to form a judgment. It is impossible that there should be such a thing as real religion without liberty. Without liberty there can be no such thing as conscience, no such word as justice. All human actions — all good, all bad — have for a foundation the idea of human liberty, and without Liberty there can be no vice, and there can be no virtue.
Without Liberty there can be no worship, no blasphemy — no love, no hatred, no justice, no progress.
Take the word Liberty from human speech and all the other words become poor, withered, meaningless sounds — but with that word realized — with that word understood, the world becomes a paradise.
