Over the last three decades, non-adaptationism has developed as an alternative model to more traditional, adaptationist approaches within Evolutionary Epistemology. Despite its great explanatory strength, non-adaptationist EE finds a potential Achilles heel in its adherence to conceptual relativism, namely the idea that empirical content can be relative to many different and radically incommensurable conceptual schemes. In his seminal essay “On the Very Idea of a Conceptual Scheme”, Donald Davidson did in fact prove the unintelligibility of an analogous form of conceptual (...) relativism. Although Davidson’s original intent was to debunk a conceptual relativist position which he discerned in the works of authors such as Kuhn, Quine, and Whorf, given the apparent similarity between the conceptual relativism supported by non-adaptationist EE and the one criticised by Davidson, one might well wonder if Davidson’s objections would have the same debunking effect if applied to non-adaptationist EE. In this paper I propose to answer this question by directing Davidson’s critiques of conceptual relativism to non-adaptationist EE and by testing to what extent the latter is de facto undermined by Davidson’s attacks. I demonstrate that Davidson’s arguments do not detract from the reliability of non-adaptationist perspectives and, to some extent, they appear to substantiate the non-adaptationist evolutionary epistemological cause anew.

Evolutionary scepticism holds that the evolutionary account of the origins of the human cognitive apparatus has sceptical implications for at least some of our beliefs. A common target of evolutionary scepticism is moral realism. Scientific realism, on the other hand, is much less frequently targeted, though the idea that evolutionary theory should make us distrustful of science is by no means absent from the literature. This line of thought has received unduly little attention. I propose to remedy this by advancing (...) what I will call an evolutionary sceptical challenge to scientific realism. I argue that, given standard evolutionary theory, our possession of sound innate metaphysical intuitions would have taken an epistemically problematic ‘lucky accident’. This, as I will show, entails that scientific realism is a self-undermining position. I discuss objections to my argument’s two premises, including ones that appeal to the success of the sciences and to the possibility that sound innate metaphysical intuitions evolved as an evolutionary ‘by-product’. I then draw out an advantage of my argument over a similar one recently put forward by Graber and Golemon. I finish by submitting that scientific realism, given the soundness of my argument, is faced with a new ‘Darwinian Dilemma’, and briefly address the significance of this for the debate between realists and anti-realists in the philosophy of science.
