In recent literature, several authors attempt to naturalize epistemic normativity by employing an etiological account of functions. The thought is that epistemic entitlement consists in the normal functioning of our belief-acquisition systems, where the latter acquire the function to reliably deliver true beliefs through a history of biological benefit.
This paper's aim is twofold. First, it puts pressure on the main proper functionalist claim; it is argued that a history of positive biological feedback is neither necessary nor sufficient for epistemic justification. Second, I suggest that this problem is sourced in a defect of application of functionalist accounts to epistemic normativity, and I offer a fix.
