The only novel thing [in the Dark Ages]<\/span> concerning probability is the following remarkable text, which appears in the False Decretals<\/cite>, an influential mixture of old papal letters, quotations taken out of context, and outright forgeries put together somewhere in Western Europe about 850. The passage itself may be much older. A bishop should not be condemned except with seventy-two witnesses … a cardinal priest should not be condemned except with forty-four witnesses, a cardinal deacon of the city of Rome without thirty-six witnesses, a subdeacon, acolyte, exorcist, lector, or doorkeeper except with seven witnesses.<\/q>⁹ It is the world's first quantitative theory of probability.

(Actually, there is some evidence that a quantitative theory of probability developed and then disappeared in ancient India.[10]<\/span> But Franklin's essential point here is none-the-less well-taken.)<\/p>
