The Consensus Gentium Argument

In antiquity the consensus gentium argument for God’s existence was believed to have merit (cf. Cicero, De Natura Deorum, Book II, sect.2,4), but has been considered blatantly fallacious during more recent times. In this article Bayes’ Theorem is applied to show that the argument is in fact a valid inductive argument. A two hypothesis and a four hypothesis version of the argument are analyzed. Perusal of available statistical evidence suggests that when better worldwide opinion polling data becomes available it will turn out to be sound as well.
