I argue that, at least on the assumption that if there are epistemic facts they are irreducible, the evolutionary debunking maneuver is prima facie self-debunking because it seems to debunk a certain class of facts, namely, epistemic facts that prima facie it needs to rely on in order to launch its debunking arguments. I then appeal to two recent reconstructions of the evolutionary debunking maneuver (Kahane (2011), Griffiths and Wilkins (2015)) and find them wanting. Along the way I set aside (...) two ways (one envisaged, the other by Sterpetti (2015)) to avoid the self-debunking problem that I find unpromising. I conclude that the evolutionary debunking maneuver needs to clarify the meta-epistemological commitments upon which it is supposed to operate. (shrink)

Debunking arguments—also known as etiological arguments, genealogical arguments, access problems, isolation objec- tions, and reliability challenges—arise in philosophical debates about a diverse range of topics, including causation, chance, color, consciousness, epistemic reasons, free will, grounding, laws of nature, logic, mathematics, modality, morality, natural kinds, ordinary objects, religion, and time. What unifies the arguments is the transition from a premise about what does or doesn't explain why we have certain mental states to a negative assessment of their epistemic status. I examine (...) the common, underlying structure of the arguments and the different strategies for motivating and resisting the premises of debunking arguments. (shrink)

Sharon Street’s evolutionary debunking argument—her Darwinian Dilemma—is meant to challenge value realists to reconcile the evaluative attitudes we tend to hold, shaped as they are by evolution, with the attitude-independent evaluative facts that realists posit. Ramon Das argues that Street’s argument relies on illicit metaphysical assumptions about evaluative facts, and that these assumptions beg the question against a particular form of value realism called naturalist realism. I argue that Street makes no such metaphysical assumptions, and that her argument requires no (...) particular metaphysical construal of evaluative facts to work. I further argue that any objection of the kind Das raises—those that turn on the metaphysical underpinnings of evaluative facts—is unlikely to succeed against Street’s Darwinian Dilemma. (shrink)
