Dallas Willard on Methodological NaturalismMoreland & Craig, eds., Naturalism: A Critical Appraisal (Routledge: 2002), p. 31.
One could retreat to a mere methodological naturalism and say that scientific method is our only hope as human beings. Whether or not we can adequately specify naturalism or know it to be true, one might say, the “scientific method” must be exclusively followed for human well-being. Naturalism would then be a humane proposal, not a philosophical claim. The proposal would be to assume in our inquiries that only the physical (or the empirical) exists and to see if inquiry based upon that assumption is not more successful in promoting human ends than any other type of inquiry.
