Epistemic Instrumentalism and Reasons for Belief: A Reply to Tom Kelly’s “Epistemic Rationality as Instrumental Rationality: A Critique”

Tom Kelly argues that instrumentalist accounts of epistemic rationality fail because what a person has reason to believe does not depend upon the content of his or her goals. However, his argument fails to distinguish questions about what the evidence supports from questions about what a person ought to believe . Once these are distinguished, the instrumentalist can avoid Kelly’s objections. The paper concludes by sketching what I take to be the most defensible version of the instrumentalist view.
