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. (shrink)

In his Dialogues and Natural Religion, David Hume offered an inductive argument claiming that the observed mixture of good and evil in the world inductively justifies belief in indifferent first causes. The existence of a benevolent, omniscient God is rejected because it is much less probable. I show that a more comprehensive analysis of Hume’s argument applying Bayes’s Theorem indicates that if the good in our world greatly outweighs the evil, theists can then claim the inductive evidence actually provides confirmation (...) for classical theism. I provide some reasons for believing that good greatly exceeds evil. Views that good modestly exceeds evil or is balanced by evil are also considered. (shrink)
