Thinkers prepare the revolution; bandits carry it out. - Arthur C. Clarke

“Censorship does raise some very difficult problems, doesn’t it? I’ve always argued that there’s an inverse correlation between a country’s degree of civilisation and the restraints it puts on its press.” A New English voice from the back of the room cut in: “On that argument, Paris is a more civilised place than Boston.” “Precisely,” answered Purvis. For once, he waited for a reply. “OK,” said the New England voice mildly. “I’m not arguing. I just wanted to check.”

The fact was that he suffered from an incurable malady which, it seemed, attacked only Homo sapiens among all the intelligent races of the universe. That disease was religious mania. Throughout the earlier part of its history, the human race had brought forth an endless succession of prophets, seers, messiahs, and evangelists who convinced themselves and their followers that to them alone were the secrets of the universe revealed. Some of them succeeded in establishing religions which survived for many generations and influenced billions of men; others were forgotten even before their deaths. The rise of science, which with monotonous regularity refuted the cosmologies of the prophets and produced miracles which they could never match, eventually destroyed all these faiths. It did not destroy the awe, not the reverence and humility, which all intelligent beings felt as they contemplated the stupendous universe in which they found themselves. What it did weaken, and finally obliterate, were the countless religions, each of which claimed with unbelievable arrogance, that it was the sole repository of the truth and that its millions of rivals and predecessors were all mistaken.

You will find men like him in all 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 religion by ignoring it as well as by disproving its tenets.
