Keith Lehrer

Keith Lehrer is a philosopher known for his work on justification in epistemology, particularly through coherentism. Coherentism suggests that beliefs are justified by their coherence with other beliefs rather than by being grounded in foundational truths. Lehrer argues for a form of internalism, where justification depends on the individual's perspective and access to their reasons. This contrasts with externalism, which allows for justification based on external factors beyond the individual's awareness. Lehrer's contributions encourage a nuanced understanding of how we validate our beliefs and the importance of both coherence and personal insight in the process of justification.
