“The mind must free itself from all kinds of “schools,” religions, sects, beliefs, etc. All those “cages” are obstacles which render the mind incapable of thinking freely. It is necessary for the mind to become free of the illusions of this world and become a fine and marvelous instrument of the Inner Being.”

Spiritual Freedom http://www.americanunitarian.org/spiritualfreedom.htm (1830)
Context: I call that mind free, which masters the senses, which protects itself against animal appetites, which contemns pleasure and pain in comparison to its own energy, which penetrates beneath the body and recognises its own reality and greatness, which passes life, not in asking what it shall eat or drink, but in hungering, thirsting, and seeking after righteousness.
I call that mind free, which escapes the bondage of matter, which, instead of stopping at the material universe and making it a prison wall, passes beyond it to its Author, and finds in the radiant signatures which everywhere bears of the Infinite Spirit, helps to its own spiritual enlightenment.
I call that mind free, which jealously guards its intellectual rights and powers, which calls no man master, which does not content itself with a passive or hereditary faith, which opens itself to light whencesoever it may come, which receives new truth as an angel from heaven.
I call that mind free, which sets no bounds to its love, which is not imprisoned in itself or in a sect, which recognises in all human beings the image of God and the rights of his children, which delights in virtue and sympathizes with suffering wherever they are seen, which conquers pride, anger, and sloth, and offers itself up a willing victim to the cause of mankind.

Variant: Some lose all mind and become soul, insane. Some lose all soul and become mind, intellectual. Some lose both and become accepted.

1920s, Truth is a Pathless Land (1929)
Context: I maintain that Truth is a pathless land, and you cannot approach it by any path whatsoever, by any religion, by any sect. That is my point of view, and I adhere to that absolutely and unconditionally. Truth, being limitless, unconditioned, unapproachable by any path whatsoever, cannot be organized; nor should any organization be formed to lead or to coerce people along any particular path. If you first understand that, then you will see how impossible it is to organize a belief. A belief is purely an individual matter, and you cannot and must not organize it. If you do, it becomes dead, crystallized; it becomes a creed, a sect, a religion, to be imposed on others. This is what everyone throughout the world is attempting to do. Truth is narrowed down and made a plaything for those who are weak, for those who are only momentarily discontented. Truth cannot be brought down, rather the individual must make the effort to ascend to it. You cannot bring the mountain-top to the valley. If you would attain to the mountain-top you must pass through the valley, climb the steeps, unafraid of the dangerous precipices.

The Functions of Criticism at the Present Time (1864)

The Saviors of God (1923)
Context: The moment is ripe: leave the heart and the mind behind you, go forward, take the third step.
Free yourself from the simple complacency of the mind that thinks to put all things in order and hopes to subdue phenomena. Free yourself from the terror of the heart that seeks and hopes to find the essence of things.
Conquer the last, the greatest temptation of all: Hope. This is the third duty.

The Rights of Man, or what are we fighting for? (1940)
Context: Throughout the whole world we see variations of this same subordination of the individual to the organisation of power. Phase by phase these ill-adapted governments are becoming uncontrolled absolutisms; they are killing that free play of the individual mind which is the preservative of human efficiency and happiness. The populations under their sway, after a phase of servile discipline, are plainly doomed to relapse into disorder and violence. Everywhere war and monstrous economic exploitation break out, so that those very same increments of power and opportunity which have brought mankind within sight of an age of limitless plenty, seem likely to be lost again, it may be lost forever, in an ultimate social collapse.
