Universal explainers

David Deutsch's term, developed in The Beginning of Infinity, for the claim that human beings are qualitatively distinct from other animals and from one another in a particular sense: any human mind, given sufficient time and the right knowledge, can in principle understand or create any explanation that any other human mind can. Differences in speed, memory, and inclination are real, but the underlying capacity for explanation is universal. The idea has provocative downstream implications for how we think about intelligence, education, parenting, and the alleged limits of any individual.
