In the past few years, the focus of arguments against theism has shifted. Where previously the existence of evil has been thought by many demonstrative of the impossibility of God's existence, now it is frequently purveyed as merely evidence against the existence of a Supreme Being. Even this more modest claim has been forcefully denied by William Alston and Peter van Inwagen. I argue that their arguments are not persuasive. Not only do they suffer logical flaws but, if accepted, actually have pernicious effects on the values of reasoning and religious practice.
