This involves an intense effort on the part of the explainer to get into the other person's mind, so to speak, and that exercise is at the heart of learning in general. For, by practicing repeatedly how to create links between my mind and another's, I am reaching the very core of the art of learning from the ambient culture. Without that skill, I can only learn from direct experience; with that skill, I can learn from the experience of the whole world. Thus, whenever I struggle to explain something to someone else, and succeed in doing so, I am advancing my ability to learn from others, too.
