The only difference between men of great achievement and those who remain in mediocrity is that the great pay little attention to what has been done and what obstacles or apparent reasons may stand in the way of achievement but devote themselves to contemplating what can or ought to be done. Those who allow their mental and emotional natures to recoil, refusing to let this sense reach out into the undiscovered, destroy their own capabilities and this keeps them always in the prison house of limitation. But it should be noted that prison is only the recoil or reflex of their own nature. Genius is that which goes on through conditions and circumstances and keeps eternally in the process of expansion and extension of achieving power.

Heaven lies about us in our infancy! Shades of the prison-house begin to close upon the growing boy, but he beholds the light, and whence it flows, he sees it in his joy; the youth, who daily farther from the east must travel, still is Nature’s priest, and by the vision splendid is on his way attended; at length the man perceives it die away, and fade into the light of common day.

From childhood upwards, everything is done to make the minds of men and women conventional and sterile. And if, by misadventure, some spark of imagination remains, its unfortunate possessor is considered unsound and dangerous, worthy only of contempt in time of peace and of prison or a traitor’s death in time of war.

One should respect public opinion insofar as is necessary to avoid starvation and keep out of prison, but anything that goes beyond this is voluntary submission to an unnecessary tyranny.

For all the practical purposes of life, truth might as well be in a prison as in the folio of a schoolman; and those who release her from her cow-webbed shelf and teach her to live with men have the merit of liberating, if not of discovering, her.

In your attempt to break down the boundaries of a personality you are building a new prison for yourself.

The worst use you can make of a man is to put him in prison.

The world is not a "prison house" but a kind of spiritual kindergarten where millions of bewildered infants are trying to spell god with the wrong blocks.

While there is a lower class I am in it, while there is a criminal element I am of it, and while there is a soul in prison I am not free.

Years ago I recognized my kinship with all living things, and I made up my mind that I was not one bit better than the meanest on the earth. I said then and I say now, that while there is a lower class, I am in it; while there is a criminal element, I am of it; while there is a soul in prison, I am not free.

The past is our cradle, not our prison, and there is danger as well as appeal in its glamour. The past is for inspiration, not imitation, for continuation, not repetition.
