“The Mathematics which effectually exercises, not vainly deludes or vexatiously torments studious Minds with obscure Subtilties, perplexed Difficulties, or contentious Disquisitions; which overcomes without Opposition, triumphs without Pomp, compels without Force, and rules absolutely without Loss of Liberty; which does not privately overreach a weak Faith, but openly assaults an armed Reason, obtains a total Victory, and puts on inevitable Chains; whose Words are so many Oracles, and Works as many Miracles; which blabs out nothing rashly, nor designs anything from the Purpose, but plainly demonstrates and readily performs all Things within its Verge; which obtrudes no false Shadow of Science, but the very Science itself, the Mind firmly adheres to it, as soon as possessed of it, and can never after desert it of its own Accord, or be deprived of it by any Force of others: Lastly the Mathematics, which depend upon Principles clear to the Mind, and agreeable to Experience; which draws certain Conclusions, instructs by profitable Rules, unfolds pleasant Questions; and produces wonderful Effects; which is the fruitful Parent of, I had almost said all, Arts, the 47 unshaken Foundation of Sciences, and the plentiful Fountain of Advantage to human Affairs.”

The trial of Charles B. Reynolds for blasphemy (1887)
Context: 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.
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.

Context: In no victory do they glory so much as in that which is gained by dexterity and good conduct without bloodshed. In such cases they appoint public triumphs, and erect trophies to the honour of those who have succeeded; for then do they reckon that a man acts suitably to his nature, when he conquers his enemy in such a way as that no other creature but a man could be capable of, and that is by the strength of his understanding. Bears, lions, boars, wolves, and dogs, and all other animals, employ their bodily force one against another, in which, as many of them are superior to men, both in strength and fierceness, so they are all subdued by his reason and understanding.

The Spiritual Espousals (c. 1340)

Original text: À côté de ces hommes religieux, j'en découvre d'autres dont les regards sont tournés vers la terre plutôt que vers le ciel ; partisans de la liberté, non seulement parce qu'ils voient en elle l'origine des plus nobles vertus, mais surtout parce qu'ils la considèrent comme la source des plus grands biens, ils désirent sincèrement assurer son empire et faire goûter aux hommes ses bienfaits : je comprends que ceux-là vont se hâter d'appeler la religion à leur aide, car ils doivent savoir qu'on ne peut établir le règne de la liberté sans celui des mœurs, ni fonder les mœurs sans les croyances ; mais ils ont aperçu la religion dans les rangs de leurs adversaires, c'en est assez pour eux : les uns l'attaquent, et les autres n'osent la défendre.
Introduction.
Source: Democracy in America, Volume I (1835)
Context: By the side of these religious men I discern others whose looks are turned to the earth more than to Heaven; they are the partisans of liberty, not only as the source of the noblest virtues, but more especially as the root of all solid advantages; and they sincerely desire to extend its sway, and to impart its blessings to mankind. It is natural that they should hasten to invoke the assistance of religion, for they must know that liberty cannot be established without morality, nor morality without faith; but they have seen religion in the ranks of their adversaries, and they inquire no further; some of them attack it openly, and the remainder are afraid to defend it.
