“It appears that liberty is bound up with imperfection, with a right to imperfection. Socialism leads to the same type of authoritarian state as Theocracy. … One must choose: either Socialism or liberty of spirit, the liberty of man's conscience. … Socialism uses a "sacred" authority and establishes a "sacred" society in which there is no place for the "lay," for the free, for choice, for the unrestrained activity of human forces.”

My Disillusionment in Russia (1923)
Context: Its first ethical precept is the identity of means used and aims sought. The ultimate end of all revolutionary social change is to establish the sanctity of human life, the dignity of man, the right of every human being to liberty and wellbeing. Unless this be the essential aim of revolution, violent social changes would have no justification. For external social alterations can be, and have been, accomplished by the normal processes of evolution. Revolution, on the contrary, signifies not mere external change, but internal, basic, fundamental change. That internal change of concepts and ideas, permeating ever-larger social strata, finally culminates in the violent upheaval known as revolution.

State Socialism and Anarchism: How Far They Agree, and Wherin They Differ (1888)
Context: The two principles referred to are Authority and Liberty, and the names of the two schools of Socialistic thought which fully and unreservedly represent one or the other of them are, respectively, State Socialism and Anarchism. Whoso knows what these two schools want and how they propose to get it understands the Socialistic movement. For, just as it has been said that there is no half-way house between Rome and Reason, so it may be said that there is no half-way house between State Socialism and Anarchism.

Improvement Era (October 1958) pp 718-719
Context: Next to life we express gratitude for the gift of free agency. When thou didst create man, thou placed within him part of thine omnipotence and bade him choose for himself. Liberty and conscience thus became a sacred part of human nature. Freedom not only to think, but to speak and act is a God-given privilege.

"Canon Law: Ecclesiastical Ministry" (1771)
Questions sur l'Encyclopédie (1770–1774)
Original: (fr) La vertu suppose la liberté, comme le transport d’un fardeau suppose la force active. Dans la contrainte point de vertu, et sans vertu point de religion. Rends-moi esclave, je n’en serai pas meilleur. Le souverain même n’a aucun droit d’employer la contrainte pour amener les hommes à la religion, qui suppose essentiellement choix et liberté. Ma pensée n’est pas plus soumise à l’autorité que la maladie ou la santé.

The trial of Charles B. Reynolds for blasphemy (1887)
Context: Gentlemen, you can never make me believe — no statute can ever convince me, that there is any infinite Being in this universe who hates an honest man. It is impossible to satisfy me that there is any God, or can be any God, who holds in abhorrence a soul that has the courage to express his thought. Neither can the whole world convince me that any man should be punished, either in this world or in the next, for being candid with his fellow-men. If you send men to the penitentiary for speaking their thoughts, for endeavoring to enlighten their fellows, then the penitentiary will become a place of honor, and the victim will step from it — not stained, not disgraced, but clad in robes of glory.
Let us take one more step.
What is holy, what is sacred? I reply that human happiness is holy, human rights are holy. The body and soul of man — these are sacred. The liberty of man is of far more importance than any book; the rights of man, more sacred than any religion — than any Scriptures, whether inspired or not.
What we want is the truth, and does any one suppose that all of the truth is confined in one book — that the mysteries of the whole world are explained by one volume?
All that is — all that conveys information to man — all that has been produced by the past — all that now exists — should be considered by an intelligent man. All the known truths of this world — all the philosophy, all the poems, all the pictures, all the statues, all the entrancing music — the prattle of babes, the lullaby of mothers, the words of honest men, the trumpet calls to duty — all these make up the bible of the world — everything that is noble and true and free, you will find in this great book.
If we wish to be true to ourselves, — if we wish to benefit our fellow-men — if we wish to live honorable lives — we will give to every other human being every right that we claim for ourselves.
