Theory of Knowledge

by Keith Lehrer

In this important new text, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the accepted definition of knowledge as justified true belief, Lehrer explores the truth, belief and justification conditions on the way to a thorough examination of foundation theories of knowledge, externalism and naturalized epistemologies, internalism and modern coherence theories as well as recent reliabilist and causal theories. Lehrer gives all views careful examination and concludes that external factors must be matched by appropriate internal ones to yield knowledge.

Readers of Professor Lehrer's earlier book Knowledge will want to know that this text adopts the framework of that classic text. But Theory of Knowledge is a completely rewritten and updated version of that book that has been simplified throughout for student use.

[Shinichuji · Rating 4 out of 5]

The author argues the status and the characteristics of knowledge, distinctly, from various perspectives. Whether one agrees or not, this book is useful for us, since we are in the age of fake news, generative AI, and so on. When the author had written this book, he couldn't imagine such the world at all(published in 1990!). So, I notice that epistemology nowadays should be not only theoretical but practical. That I was impressed from this book is to know something is not just to have information. We need more. Even if AI can reply anything frequently, they know nothing. We must keep this in mind carefully.
