Abstract: Six kinds of Pascal's Wager are explored via a look at decision theory and the logic of pragmatic arguments. Of these six, one version dubbed ‘the Jamesian Wager’, in honour of William James's argument in his 1896 essay The Will to Believe, is the focus of an extended treatment throughout the book. It is a primary contention of the book that the Jamesian Wager provides a sound argument in support of theistic belief.

Keywords: decision theory, William James, Maximin,
