Darwin is well known for his wondrously ambiguous rhetoric. The author who used an ‘entangled bank’ as his metaphor for Nature and its complex relationships built up the substance of his text from a corresponding entanglement of unresolved theoretical relations. Ambiguous positions, arguments that seem to fold in on themselves, vacillations, contradictions, and pluralities of explanation suffuse Darwin's science and its constituent metascience. The Origin abounds in ambiguities with regard to the technical features of evolutionary biology. But the domain of (...) ambiguity I wish to address is Darwin's metaphysical stance. I want to approach the question of Darwin and secularization through what might be called the trope of ambiguity. My principle concern is with the origins of that ambiguity. These lie in the conflicting cultural and ideological resources Darwin used to construct the theory of natural selection. (shrink)

Although scholars have paid careful attention to the naturalistic content of the Origin, less focus has been given to Darwin’s strategic deployment of methodological naturalism in the volume. A close inspection shows that he did not use methodological naturalism statically in the six editions of the Origin; instead, he strategically and progressively invoked methodological naturalism in the six editions of the Origin in order to enhance the persuasiveness of his theory and to marginalize special creation from the scientific discussion. In (...) particular, Darwin’s explicit use of methodological naturalism in later editions of the Origin was animated less by epistemic reasons and more by expedient ones. Thus, while Darwin personally may have had sound epistemic grounds for methodological naturalism, his increasing deployment of the method in the Origin seems to have been mainly for the purpose of winning converts to his theory and ostracizing special creation rather than making a strong empirical and philosophical case per se for his position.
