Albert Casullo (2000, 2003) and Shane Oakley (2011) argue that dilemma arguments against epistemic naturalism, such as those offered by Laurence BonJour (1998) and Harvey Siegel (1984), are such that, whatever strength they have against naturalism applies equally to moderate rationalist accounts of a priori justification. They conclude that dilemma arguments are, therefore, insufficient for establishing an advantage for moderate rationalism over naturalized epistemology. I argue that both Casullo's and Oakley's criticisms depend on an illicit assumption, namely, that dilemma arguments (...) presuppose a meta-justificatory demand that naturalists provide non-circular support for their basic sources of evidence. I argue that this assumption is not necessary for the force of dilemma arguments, and I construct a version that avoids this misreading. I conclude that, although there remain strategies for responding to dilemma arguments, they constitute a challenge naturalists must take seriously. (shrink)

We discuss Russell's 1913 essay arguing for the irrelevance of the idea of causation to science and its elimination from metaphysics as a precursor to contemporary philosophical naturalism. We show how Russell's application raises issues now receiving much attention in debates about the adequacy of such naturalism, in particular, problems related to the relationship between folk and scientific conceptual influences on metaphysics, and to the unification of a scientifically inspired worldview. In showing how to recover an approximation to Russell's conclusion (...) while explaining scientists' continuing appeal to causal ideas (without violating naturalism by philosophically correcting scientists) we illustrate a general naturalist strategy for handling problems around the unification of sciences that assume different levels of naïveté with respect to folk conceptual frameworks. We do this despite rejecting one of the premises of Russell's argument, a version of reductionism that was scientifically plausible in 1913 but is not so now. (shrink)
