 Foundationalism is the view that some beliefs are epistemologically basic—i.e., their justification does not depend on evidential support from other beliefs—and all other beliefs ultimately derive their justification from basic beliefs. (Basically justified beliefs are sometimes referred to as “immediately justified” or “directly justified” as well.) Classical foundationalism is the view that (i) it is appearance beliefs—i.e., beliefs about perceptual appearances—that are basic, and perceptual beliefs about ordinary objects are based at least partly on these, and (ii) perceptual justification requires us to have good reason to think that the relevant current appearances are veridical. Basing is a relation of epistemic dependence and does not imply explicit inference, although particular theories might hold that the relation is satisfied only when inference occurs.
