“There is the image of the man who imagines himself to be a prisoner in a cell. He stands at one end of this small, dark, barren room, on his toes, with arms stretched upward, hands grasping for support onto a small, barred window, the room's only apparent source of light. If he holds on tight, straining toward the window, turning his head just so, he can see a bit of bright sunlight barely visible between the uppermost bars. This light is his only hope. He will not risk losing it. And so he continues to staring toward that bit of light, holding tightly to the bars. So committed is his effort not to lose sight of that glimmer of life-giving light, that it never occurs to him to let go and explore the darkness of the rest of the cell. So it is that he never discovers that the door at the other end of the cell is open, that he is free. He has always been free to walk out into the brightness of the day, if only he would let go.
