Methodological naturalists generally believe that science is the best and only method for discovering the properties of reality and what exists. A central tenet of methodological naturalism is that science is limited to evaluating only natural things. Science cannot allow for the possibility of supernatural objects because doing so would irreparably damage the scientific method. Or, it may be that evaluating the supernatural is beyond the capabilities of science. In this thesis, I challenge these assumptions. I defend a form of (...) naturalism known as Provisory Methodological Naturalism which holds that science can, at least theoretically, evaluate supernatural claims. Provisory methodological naturalists believe the notion that science only evaluates natural things is provisional and subject to being overruled. Should supernatural objects exist, science would be able to observe them. (shrink)
