Foundationalism

In Epistemology, the Internalist position which holds a belief is epistemically justified in one of two ways:

  1. If it is self-evidently true and therefore self-justifying (sometimes referred to as “terminal” beliefs because they are the termination point in the chain of justification)

  2. If it is rationally derived directly or indirectly from a foundational belief which, because of its self-evident nature, requires no further justification.

This model of Internalist justification is often characterized as linear since justification travels directly from foundational beliefs upward to non-terminal beliefs.
