Of Simulations and Conscious Universes: Explaining Fine-Tuning Without God

Expositions of the fine-tuning argument (FTA) typically aim only to show that cosmic fine-tuning is evidence for theism over specific versions of naturalism. But, construed as an argument for theism, that modest contention threatens the FTA with insignificance, as there may be other hypotheses that better explain fine-tuning than either theism or one’s preferred formulation of naturalism. Adopting a Bayesian framework, I assess four such possibilities: the simulation hypothesis, teleological cosmopsychism, axiarchism, and teleological laws. I conclude that theism is superior to all four.
