The most anxious man in a prison is the governor.

We think caged birds sing, when indeed they cry.

Stone walls do not a prison make nor iron bars a cage.

A man will be imprisoned in a room with a door that's unlocked and opens inwards; as long as it does not occur to him to pull rather than push.

All my life I had feared imprisonment, the nun's cell, the hospital bed, the places where one faced the self without distraction, without the crutches of other people.

We are all serving a life sentence in the dungeon of the self.

Whatever you hold in contempt is your jailer.

Two men look out through the same bars: One sees the mud, and one the stars.

Stone walls do not a prison make, Nor iron bars a cage.

If you ever get twenty-five years for nothing, if you find yourself wearing four number patches on your clothes, holding your hands permanently behind your back, submitting to searches morning and evening, working until you are utterly exhausted, dragged into the cooler whenever someone denounces you, trodden deeper and deeper into the ground-from the hole you're in, the fine words of the great humanists will sound like the chatter of the well-fed and free.
