David Henderson

David Henderson is a philosopher known for his work on the concepts of internalism and externalism, particularly in epistemology, which studies knowledge. Internalism suggests that justification for beliefs comes from factors within a person's mind, such as their thoughts and experiences. In contrast, externalism argues that justification can depend on outside factors, like the reliability of the process used to form beliefs. Henderson's contributions help clarify these positions, exploring how our understanding of knowledge may depend on either internal factors (what we think) or external factors (how beliefs are formed in the world).
