On the necessity of the evidential equality condition for epistemic peerage

Abstract

A popular definition of epistemic peerage maintains that two subjects are epistemic peers if and only if they are equals with respect to general epistemic virtues and share the same evidence about the targeted issue. In this paper I shall take up the challenge of defending the necessity of the evidential equality condition for a definition of epistemic peerage from criticisms that can be elicited from the literature on peer disagreement. The paper discusses two definitions that drop this condition and argues that they yield implausible verdicts about the instantiation of the epistemic peerage relation.
