There are similarities between absolute power and absolute faith: a demand for absolute obedience, a readiness to attempt the impossible, a bias for simple solutionsto cut the knot rather than unravel it, the viewing of compromise as surrender. Both absolute power and absolute faith are instruments of dehumanization. Hence, absolute faith corrupts as absolutely as absolute power.
In the Middle Ages people believed that the earth was flat, for which they had at least the evidence of their senses: we believe it to be round, not because as many as 1 percent of us could give the physical reasons for so quaint a belief, but because modern science has convinced us that nothing that is obvious is true, and that everything that is magical, improbable, extraordinary, gigantic, microscopic, heartless, or outrageous is scientific.
