He Prayed the Rosary

One hundred years ago a university student found himself beside a man who seemed to be a well-to-do peasant.
The man was praying the rosary.
The student asked, "Sir, why do you believe in such an outdated thing?
Why don't you throw your rosary out the window and use your time to study science?"
"Science? You think I do not understand science? Perhaps you can teach me."
The student said, "Sure, I'll help you, give me your name and address and I'll send you some literature."
The man fumbled in the pocket of his coat and finally found one of his cards.
Upon glancing at the card, the student bowed his head in shame and became silent.
The card read: "Louis Pasteur, Director of the Institute of Scientific Research, Paris."
