     "Dr. Papaderos, what is the meaning of life?"

     The usual laughter followed, and people stirred to go. Papaderos held up his hand and stilled the

room and looked at me for a long time, asking with his eyes if I was serious and seeing from my eyes

that I was.

     "I will answer your question."

     Taking his wallet out of his hip pocket, he fished into a leather billfold and brought out a very small

round mirror, about the size of a quarter. And what he said went like this:

     "When I was a small child, during the war, we were very poor and we lived in a remote village. One

day, on the road, I found the broken pieces of a mirror. A German motorcycle had been wrecked in that

place.

     I tried to find all the pieces and put them together, but it was not possible, so I kept only the largest

piece. This one, and, by scratching it on a stone, I made it round. I began to play with it as a toy and

became fascinated by the fact that I could reflect light into dark places where the sun would never

shine-in deep holes and crevices (裂缝) and dark closets. It became a game for me to get light into the

most inaccessible places I could find.

     I kept the little mirror, and, as I went about my growing up, I would take it out in idle moments and

continue the challenge of the game. As I became a man, I grew to understand that this was not just a

child's game but a metaphor for what I might do with my life. I came to understand that I am not the

light or the source of light. But light-truth, understanding, knowledge-is there, and it will shine in many

dark places only if I reflect it.

     I am a fragment (碎片) of a mirror whose whole design and shape I do not know. Nevertheless,

with what I have I can reflect light into the dark places of this world-into the black places in the hearts

of men-and change some things in some people. Perhaps others may see and do likewise. This is what

I am about. This is the meaning of my life."
