Map and Territory is the first book contained in the ebook Rationality: From AI to Zombies, by Eliezer Yudkowsky. It is the edited and expanded version of a series of blog posts in "the Sequences", and discusses the nature of rationality, belief, and explanation.
Map and Territory contains four sequences of essays, which are followed by the stand-alone essay The Simple Truth. These are all collected in the Rationality: From AI to Zombies ebook, but the essay names below are also linked to the original blog posts.
The next book in the series is How to Actually Change Your Mind.
