This is a concise guide to epistemology, the study of knowledge and how knowing relates to believing (if at all) as well as to truth. After discussing the meaning and ubiquity of the word “knowledge,” the book explores a couple varieties of skepticism – the idea that there is nothing (or, at least, very little) that one can know with certainty. Skepticism is correct in a sense, but is also dissatisfying and arguably irrelevant, and this led to many attempts to produce a more nuanced understanding of knowledge. The book proceeds to evaluate the major contenders, rationalism (knowledge comes from reason) and empiricism (knowledge comes from experience,) pointing out the strengths and limitations of each.

The book next challenges the definition of knowledge as “justified true belief.” It considers how justification can be a problem through Gettier Problems – scenarios in which an individual is correct in their conclusion but incorrect in their justification. The author then questions what is justification and what are the problems with various approaches, explaining internalism, externalism, and testimony in the process. The book moves on to various sliding scale approaches – e.g. saying that it’s perfectly acceptable to say one knows something if it’s likely true and the stakes are small, whereas, if the stakes are large, one is forced to be more skeptical. The final chapter dives into the interface of psychology and epistemology, reflecting upon our intuitions and the biases reflected in them.

While the subject matter might seem dry, I felt the author did a great job of presenting scenarios by which one could more easily wrap one’s head around the ideas than one would be able to via abstract thinking. The writing style is clear and easy to follow.

If you’re looking to understand the challenges confronted in epistemology, this is a great book to start your study.
