%0 Journal Article %T Process Externalism and mental causation: setting metaphysical bounds on cognitive science %A Camilo Ramirez Motoa %J Adaptive Behavior %@ 1741-2633 %D 2019 %R 10.1177/1059712318793836 %X In this article, I examine the argument by which Process Externalism¡ªan interesting empirical theory that echoes 4E¡¯s core ideas¡ªundermines Kim¡¯s supervenience argument. If mental properties do not depend exclusively on neurological properties but depend on external or extra-cranial properties, mental causation cannot be pre-empted by or reduced to neurological properties. In this sense, Keijzer and Schouten argue that this theory entails a robust nonreductive materialism (RNM) that vindicates a notion of mental causation. However, I will argue that this maneuver produces different kinds of overdetermination problems that compromise the metaphysical austerity of a materialist theory of cognition and, for this reason, Process Externalism might not be conceived as entailing an RNM. Finally, I will suggest that the theory could be rendered as a moderate reductive account of the cognitive phenomena that would avoid the overdetermination problems that haunt nonreductive accounts of cognition %K Supervenience argument %K Process Externalism %K mental causation %K robust nonreductive materialism %K causal overdetermination %K non-causal overdetermination %U https://journals.sagepub.com/doi/full/10.1177/1059712318793836
