Abstract

SummaryThis article discusses whether a naturalistic philosopher should endorse the epistemological version of the “is/ought gap” thesis. Quine thinks that there is an epistemological gap between normative epistemology and normative ethics, but I claim that anybody holding his naturalistic and holistic views has good reasons to deny the existence of a gap separating either epistemology from ethics or descriptive discourse from nonnative discourse. I maintain that both gaps can be bridged if one adopts, like Quine, a holistic view of justification. Although justification in science, epistemology and ethics are different in certain respects, holism accounts for the justification of scientific, epistemological and ethical beliefs at a general level.
