Knowledge: Traditionally defined as justified true belief—a belief that is both true and supported by adequate justification. It is the aim of epistemology to understand its nature and scope.
Belief: A psychological state where an individual holds a proposition to be true. Beliefs can be true or false, but only true beliefs can qualify as knowledge when justified.
Justification: The evidence, reasons, or grounds that support a belief, distinguishing knowledge from mere belief. Justification ensures that beliefs are rational and credible.
Truth: A property of propositions that accurately reflect reality. Different theories of truth include correspondence (matching reality), coherence (consistency within a system), and pragmatism (usefulness).
Epistemic Justification: The process or reasons that make a belief rational or warranted, which is essential for transforming true belief into knowledge.
Gettier Problem: Challenges the traditional definition by presenting scenarios where justified true belief does not seem to constitute knowledge, prompting reevaluation of the criteria.
