Pain and Pleasure: An Evidential Problem for Theists

Paul Draper's "Pain and Pleasure: An Evidential Problem for Theists" presents a sophisticated probabilistic argument against theism based on the distribution of pain and pleasure in the world. Rather than claiming that suffering definitively disproves God's existence, Draper develops an evidential argument suggesting that the patterns of pain and pleasure observed in nature are more probable on the hypothesis of indifference than on theism.

The article introduces the "Hypothesis of Indifference" (HI), which states that neither nature nor any supernatural beings care about the well-being of sentient creatures. Draper argues that when comparing this hypothesis with theism, the actual distribution of pain and pleasure in the world - including its apparent randomness, evolutionary origins, and biological functions - is antecedently more probable given HI than given theism. This creates what he terms an evidential problem, as opposed to a logical problem, for theistic belief.

Draper's methodology employs careful probabilistic reasoning, distinguishing his approach from traditional logical arguments from evil. He examines specific features of pain and pleasure: their biological utility, their distribution among different creatures, and their relationship to moral agency. The argument acknowledges that theism could explain these phenomena through various theodicies, but maintains that such explanations are less probable than the straightforward naturalistic account offered by HI.

The work engages primarily with contemporary analytic philosophy of religion, responding to defenses of theism by philosophers like Richard Swinburne and Alvin Plantinga. Draper's innovation lies in shifting the debate from deductive disproof to comparative probability assessments. He argues that even if theism remains logically possible and can accommodate the existence of suffering through free will or soul-making theodicies, the specific patterns of pain and pleasure we observe still count as evidence against it.

This article has proven influential in philosophy of religion by establishing a new framework for evidential arguments from evil. Its careful attention to empirical details about pain and pleasure, combined with rigorous probabilistic analysis, demonstrates how naturalistic explanations can challenge theistic worldviews without claiming absolute disproof. The work exemplifies the analytical tradition's emphasis on precise argumentation while engaging seriously with empirical observations about suffering in nature.
