Theory of Knowledge

Theory of Knowledge presents a systematic philosophical investigation of the nature and limits of human knowledge. Keith Lehrer develops his coherence theory of knowledge through careful analysis of belief, truth, and justification. The book examines key epistemological questions about how we acquire and validate knowledge claims. Lehrer builds his argument through discussions of skepticism, perception, memory, induction, and other fundamental aspects of knowing. Each chapter confronts major challenges to knowledge while advancing Lehrer's coherentist framework. The work engages with both historical philosophical perspectives and contemporary debates in epistemology. The text stands as an influential contribution to epistemological theory, offering a cohesive system for understanding how knowledge claims can be justified within a web of mutually supporting beliefs. Lehrer's analysis has implications for fields ranging from science to ethics.

Philosophy students appreciate its systematic approach and clear explanations of complex concepts.

🔹 Keith Lehrer developed his coherence theory of knowledge over several decades, refining it through multiple editions of this book, making it one of the most comprehensive treatments of epistemology from a coherentist perspective. 🔹 The book introduces Lehrer's unique "trustworthiness" account of knowledge, which argues that knowledge requires not just justified true belief, but also that the believer must be trustworthy in their acceptance of the belief. 🔹 Published in 1990, this work emerged during a pivotal time in epistemology when philosophers were actively debating solutions to the Gettier problems that had challenged traditional definitions of knowledge. 🔹 Lehrer's theory influenced both analytic epistemology and artificial intelligence research, as his ideas about how beliefs should cohere with each other helped inform early work on reasoning systems and knowledge representation. 🔹 The book addresses skepticism by proposing that while we cannot completely eliminate doubt, we can achieve knowledge through a system of mutually supporting beliefs that are more reasonable to accept than reject.
