Abstract

An increasing number of epistmeologists claim that having beliefs which are reliable is a prerequisite of having epistemically rational beliefs. Alvin Goldman, for instance, defends a view he calls “historical reliabilism.” According to Goldman, a person S rationally believes a proposition p only if his belief is caused by a reliable cognitive process. Goldman adds that a proposition p is epistemically rational for 5, whether or not it is believed by him, only if there is available to S a reliable cognitive process which if used would result in S’s believing p. Likewise, Marshall Swain, Ernest Sosa, and William Alston all claim that reliability is a prerequisite of epistemic rationality. Swain claims that S rationally believes p only if he has reasons for p which are reliable indicators that p is true. Sosa says S rationally believes p only if the belief is the product of an intellectual virtue, where intellectual virtues are stable dispositions to acquire truths. And, Alston says that S rationally believes p only if the belief is acquired or held in such a way that beliefs held in that way are reliable, i.e., mostly true.
