“The essence of Vanderbilt is still learning, the essence of its outlook is still liberty, and liberty and learning will be and must be the touchstones of Vanderbilt University and of any free university in this country or the world. I say two touchstones, yet they are almost inseparable, inseparable if not indistinguishable, for liberty without learning is always in peril, and learning without liberty is always in vain.”

What Is Anarchism? (1929), Ch. 26: "Preparation" http://libcom.org/library/what-is-anarchism-alexander-berkman-26
Context: If your object is to secure liberty, you must learn to do without authority and compulsion. If you intend to live in peace and harmony with your fellow-men, you and they should cultivate brotherhood and respect for each other. If you want to work together with them for your mutual benefit, you must practice cooperation. The social revolution means much more than the reorganization of conditions only: it means the establishment of new human values and social relationships, a changed attitude of man to man, as of one free and independent to his equal; it means a different spirit in individual and collective life, and that spirit cannot be born overnight. It is a spirit to be cultivated, to be nurtured and reared, as the most delicate flower it is, for indeed it is the flower of a new and beautiful existence.

Second Reply to Hayne (1830)
Context: When my eyes shall be turned to behold for the last time the sun in heaven, may I not see him shining on the broken and dishonored fragments of a once glorious Union; on States dissevered, discordant, belligerent; on a land rent with civil feuds, or drenched, it may be, in fraternal blood! Let their last feeble and lingering glance rather behold the glorious ensign of the republic, now known and honored throughout the earth, still full high advanced, its arms and trophies streaming in the original lustre, not a stripe erased or polluted, nor a single star obscured, bearing for its motto, no such miserable interrogatory as 'What is all this worth?' nor those words of delusion and folly, 'Liberty first and Union afterward,'; but everywhere, spread over all the characters of living light, blazing on all its ample folds, as they float over the sea and over the land, and in every wind under the whole heavens, that other sentiment, dear to every true American heart, -- Liberty and Union, now and forever, one and inseparable!

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.
