[[Explanations are narratives that help minds understand their perceptions]] To people, the best known knowledge is a good explanation. [[Knowledge is information that causes itself to be replicated]]. [[In good explanations, all details play a functional role in their explanatory power]]. Using terms from [[Information Theory of Minds]], we can say that with enough model capacity to understand its inputs, and enough time to explore various inference chains, a mind could explain anything, in principle.
