 Laurence BonJour (1985: ch. 4) raised a highly influential objection to foundationalism (an objection raised before he joined the ranks of foundationalists). The objection presupposed a strong form of what we might call access internalism. (We discuss the internalist/externalist controversy in more detail in  section 6  below.) The access internalist argues, roughly, that a feature of a belief or epistemic situation that makes a belief foundationally justified for us must be a feature to which we have actual or potential access. Moreover, we must have access to the fact that the feature in question is relevant to the truth or probability of what we believe. Suppose some foundationalist offers an account according to which a belief B is foundationally justified only if it has some characteristic X. BonJour argues that the mere fact that the belief has X could not justify the believer in holding B. The believer would also need access to the fact that B has X and that beliefs of this sort are likely to be true. But according to the strong access requirement BonJour accepts, this requires actual or potential knowledge or justified belief that B has X and that beliefs of this sort are likely to be true. So B would need other justified beliefs for its justification. B’s status as a foundationally justified belief is destroyed.
