Conclusion 240 .1 REFERENCES 2 42 8 ABSTRACT The leading versions of epistemic naturalism have attempted to make normative accounts of justification and knowledge in part dependent upon scientific psychology. Call \h\^ docinxxQ psychologistic naturalism. Psychologistic naturalism, it is thought, holds the promise of integrating normative questions about the relation between evidence and belief with a physicalist, causal conception of our mental life. In Part One of this essay I argue that psychologistic naturalism fails. My reasons for claiming this differ significantly from those advanced in the contemporary literature by epistemic non-naturalists, however. Non-naturalists have mistakenly accepted the terms of debate set by psychologistic naturalists, and thus they have argued that the empirical results of the science of the mind — as part of a merely descriptive causal account of natural systems — have no important place in epistemology. But psychologistic naturalism does not fail because psychology is causal and descriptive, as the non-naturalist alleges. It fails, instead, because psychology is not wholly or even primarily causal and descriptive. Psychology requires a robust normative account of rational inference in order to offer explanations within acognitivist framework. The inadequacy of psychologistic naturalism may seem to invite a return to epistemology as first philosophy, where the primary methodology deploys a priori intuitions about cases. In Part Two, I argue that this is not the best response to the instability of psychologistic naturalism. If psychological explanations e.vpress an embedded normative component, then the non-naturalist's objections to a liaison between epistemology and psychology are misguided. I pursue an epistemology in the scientific image, where psychological explanations encode a normative epistemic component and where the states of natural cognizers are characterized at a finer resolution than beliefs. Psychological explanation involves an evaluation of the inferential cogency of each step in a 9 cognitive process, and I replace the traditional methodology of epistemology with this more subtle and nuanced version of epistemic appraisal. 10 CHAPTER ONE: EPISTEMOLOGY, METAEPISTEMOLOGY & TWO RIVAL IMAGES OF MIND In spite of a history of on-again off-again infatuation with science, philosophers recognize that the challenge of explaining and predicting and analyzing the world around us can be met in non-scientific ways. As Sellars puts it, ...the philosopher is not confronted by one complex many-dimensional picture, the unity of which, such as it is, he must come to appreciate; but by two pictures of essentially the same order of complexity, each of which purports
