The Machine in the Ghost is the third book contained in the ebook Rationality: From AI to Zombies, by Eliezer Yudkowsky. It covers topics related to cognition, concepts, and the general notion of goal-oriented behavior.

The Machine in the Ghost contains three sequences of thematically connected essays, plus the stand-alone essay An Intuitive Explanation of Bayes's Theorem. These are all collected in the Rationality: From AI to Zombies ebook, but the essay names below also link to the original blog posts.

The previous book in the series is How to Actually Change Your Mind, and the next book is Mere Reality.
