Mankind's language is understood, to be sure, by every spirit wherever born, even by those from the planet Jupiter. But because they are heavenly beings and [communicate by] thinking, they therefore have a kind of mental pictorial language that they do not even express by words, but only by more or less panoramic mental images. Whereas our speech, broken up into words, has to be gathered like scattered pieces, and then shaped into a continuous mental image. This is the reason it was said that this speech is hardly understood, because words outline a general mental image in such a scattered manner, while the spirits of Jupiter cover more in a moment than we do in many moments, including things that [to us] are hardly expressible. It is as when a person is concentrating on the thoughts [of someone speaking]-he can understand better than one who holds his thought on the language, only on the words, or, as they say, on the lips, which is the outside. 1748, 2 March.
