In his most recent book—Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly False—and in numerous places in his previous work, Thomas Nagel wishes to suggest several reasons that theism is not a live option for him (to use a phrase made famous by William James). He does not seem to intend many of his criticisms to be more than suggestive, much less decisive; nonetheless, in light of the strength of his conviction that theism is somehow inherently too outrageous an option to believe, I would like to spend a bit of time identifying and assessing the criticisms he mentions.
