AN ARGUMENT OVER ‘METHODOLOGICAL NATURALISM’ AT THE VATICAN OBSERVATORY

Abstract

This paper is framed as a continuation of a 12th century debate over whether a ‘profane’ account of nature without reference to arbitrary divine acts in its workings (secundum phisicam) threatens the unity of scriptura et natura that was assumed in the natural philosophy which developed out of the Platonic/Augustinian tradition. Currently this issue takes the form of either a commitment to or circumvention of the protocol of ‘methodological naturalism’ in the explanation of natural history, most clearly with regard to evolutionary theory. The focus of the paper is on the latent disagreement over this issue between two poles of the steering committee which oversaw a series of conferences co‐sponsored by the Vatican Observatory. One sidei was willing to make a sustained commitment to ‘methodological naturalism’, arguing that while nature was not self‐explanatory, its inherent characteristics were sufficient for explaining the course of natural history. The other sideii was initially willing to concede the protocol, but ultimately saw the unity of scriptura et natura threatened. After the introduction, Section II analyzes specific disagreements between the two groups over theological epistemology, theological language, and God as a necessary factor in the explanans of natural history. That analysis becomes the basis in Section III for the assertion that the strategy of the second group involves returning to an older form of natural philosophy with a doxa‐episteme progression that allows it to augment the ‘profane’ epistemology of ‘methodological naturalism’ with an esoteric insight in order to recognize what is ‘objectively’ the case. Natural philosophies of this sort permit a ‘semantic variability’ such that the designation of a claim as ‘theological’ can mean that it both is and is not a semantic alternative to claims that follow the protocol of ‘methodological naturalism’. The strength given the claim will depend on the discourse context. The paper concludes with a chart of the multiple and significant differences between the two groups.
