John Pollock

John Pollock was a prominent philosopher known for his work on epistemology, the study of knowledge. He contributed to coherentism, which proposes that beliefs are justified if they fit coherently within a network of other beliefs. Pollock also explored internalism and externalism, two theories about the sources of justification. Internalism argues that justification comes from within an individual's mental states, while externalism claims it can depend on external factors, like the reliability of the belief-forming process. Pollock's ideas helped clarify how we understand knowledge and justification, emphasizing the complexities of how we form and validate our beliefs.
