Unlike other classical arguments for the existence of God, Pascal’s Wager provides a pragmatic rationale for theistic belief. Its most popular version says that it is rationally mandatory to choose a way of life that seeks to cultivate belief in God because this is the option of maximum expected utility. Despite its initial attractiveness, this long-standing argument has been subject to various criticisms by many philosophers. What is less discussed, however, is the rationality of this choice in situations where the (...) decision-makers are confronted with greater uncertainty. In this paper, I examine the imprecise version of Pascal’s Wager: those scenarios where an agent’s credence that God exists is imprecise or vague rather than precise. After introducing some technical background on imprecise probabilities, I apply five different principles for decision-making to two cases of state uncertainty. In the final part of the paper, I argue that it is not rationally permitted to include zero as the lower probability of God’s existence. Although the conditions for what makes an act uniquely optimal vary significantly across those principles, I also show how the option of wagering for God can defeat any mixed strategy under two distinct interpretations of salvation.

This article explores “pragmatic arguments” for theistic belief – that is, arguments for believing in God that appeal, not to evidence in favor of God’s existence, but rather to alleged practical benefits that come from belief in God. Central to this exploration is a consideration of Jeff Jordan’s recent defense of “the Jamesian wager,” which portrays itself as building on the case for belief presented in William James’s essay “The Will to Believe.” According to Jordan, religious belief creates significant gains (...) in this‐worldly happiness , and provided the individual does not have decisive evidence against God’s existence, these gains give the individual sufficient reason to strive to believe in God. In its exploration of this argument, the article presents an overview of recent social scientific work on the this‐worldly effects of religious belief. It canvases several challenges to pragmatic arguments, namely, a challenge according to which happiness rooted in false belief is worth less than that rooted in truth, a perfectionistic challenge alleging that one should strive for personal excellence rather than happiness, and a challenge alleging that any happiness gains of religious belief are outweighed by the potential harms brought about by religious belief.
