 Such an absolute belief in naturalism is commonly referred to as "metaphysical naturalism".Assuming naturalism in working methods as the current paradigm, without the further consideration of naturalism as an absolute truth with philosophical entailment, is called "methodological naturalism".With the exception of pantheists—who believe that Nature is identical with divinity while not recognizing a distinct personal anthropomorphic god—theists challenge the idea that nature contains all of reality.
