 Thus, according to Quine, the central concern of epistemology is the theory-evidence relationship; if the foundationalist story about this relationship is a failure, then that leaves only one story worth telling about this relationship: namely, the story told by “a purely descriptive, causal-nomological science of human cognition” (Kim 1988, p. 388). The science of human cognition replaces armchair epistemology: we naturalize epistemology by turning over its central question—the relationship between theory and evidence—to the relevant empirical science.
