"When I was in college, the fundamentalist evangelical types had no effect when they buttonholed me—I made fun of them. And yet a scientist, who taught of the evidence for God in physics, and who occasionally had some salt in his language, had a profound impact. If he had been different in all things (as Bob means it, if I understand correctly), including his evangelism, I would have ignored him just like I ignored the others who were different in all things."
