As an amateur reader of epistemology, it is difficult to give an in-depth critique of the book. I rate it highly because the book is an assortment of key topics in logic and critical thinking: statistics and probability, Bayesian reasoning, logical fallacies, game theory, rational choice and expected utility, and the relationship between correlation and causation. The book reads less like Mr. Pinker's voice than a hotchpotch of ideas of thinkers and philosophers that have preceded him. The references and authors to which the book adverts make for resourceful further readings.

Owing to the technical nature of the topics discussed, parts of Rationality read like a textbook. Nonetheless, these esoteric parts constitute a fringe rather than a mass. It helps that Pinker employs quip, humour, and real-world examples to explain some concepts. A good introductory text to epistemology.
