‘Three axioms presupposed by the scientific method are realism (the existence of objective reality), the existence of observable natural laws, and the constancy of observable natural law. Rather than depend on provability of these axioms, science depends on the fact that they have not been objectively falsified.
Occam’s razor and related appeals to simplicity are epistemological preferences, not general principles of science. The general principle of science is that theories (or models) of natural law must be consistent with repeatable experimental observations. This principle rests upon the unproven axioms mentioned above. Occam’s razor supports, but does not prove, these axioms.’
