The second, which can be labeled the indirect inductive approach, argues instead that theism can be shown to be unlikely to be true by establishing that there is some alternative hypothesis—other than the mere negation of theism—that is logically incompatible with theism, and more probable than theism. This approach, which was originally used by David Hume in one of his arguments in his Dialogues Concerning Natural Religion, and which has been set out and defended in a detailed way by Paul Draper, can be viewed as involving an inference to the best explanation, a type of inductive inference that was discovered by C. S. Pierce, and which is now very widely accepted.
