An elaboration on episode 49's description of the brain as a prediction engine, focusing on a theory of what emotions are, how they're learned, and how emotional experiences are constructed. Emotions like anger and fear turn out to be not that different from concepts like money or bicycle, except that the brain attends more to internal sensations than to external perceptions.

If the predictive brain theory is true, the brain is stranger than we imagine; perhaps stranger than we can imagine.
