Pascal makes no attempt in this most famous argument to show that his Roman Catholicism is true or probably true. The reasons which he suggests for making the recommended bet on his particular faith are reasons in the sense of motives rather than reasons in the sense of grounds. Conceding, if only for the sake of the present argument, that we can have no knowledge here, Pascal tries to justify as prudent a policy of systematic self-persuasion, rather than to provide grounds for thinking that the beliefs recommended are actually true.
