Explanations

…it is said that the mind can know nothing: it can know nothing because it needs explanations. An explanation is valuable only to the extent it gives you a power to act on the thing explained, otherwise what’s the good of it? If explaining something does not give you the power to change it, it is absolutely useless, because, as I said, the explanation you give entails another explanation, and so on. But if through an explanation you obtain some power over a thing, to make it different from what it is, then it’s worth the trouble.
