From Arthur C. Clarke, the sci-fi writer for whom we can thank for 2001: A Space Odyssey, from "Childhood's End"
Quote:"You will find men like him in all of the world's religions. They know that we represent reason and science, and, however confident they may be in their beliefs, they fear that we will overthrow their gods. Not necessarily through any deliberate act, but in a subtler fashion. Science can destroy a religion by ignoring it as well as by disproving its tenets. No one ever demonstrated, so far as I am aware, the nonexistence of Zeus or Thor, but they have few followers now."
