Naturalism is the view that the scientific metho (hypothesize, predict, test, repeat) is the only effective way to investigate reality. Naturalism does not necessarily claim that phenomena or hypotheses commonly labeled as supernatural do not exist or are wrong, but insists that all phenomena and hypotheses can be studied by the same methods and therefore anything considered supernatural is either nonexistent or not inherently different from natural phenomena or hypotheses. Some naturalists also insist that a legitimate distinction between supernatural entities and natural entities cannot be properly made (focusing on the conceptual distinction itself), and that when someone is talking or thinking about supernatural entities, they are actually referring to natural entities (though confusedly).
