of e and i. Because it is especially in tones that affections express themselves, so in human speech, when great subjects are discussed, such as heaven [caelum] and God [Deus], those words are preferred that contain the vowels u and o; and musical tones, whenever such themes are to be expressed, rise to the same fullness; but not when less exalted themes are rendered. By such means musical art is able to express affections of various kinds. {Footnote 1} [As these vowels are pronounced in European language. -- Tr.] 242. In angelic speech there is a kind of symphony that cannot be described;{1} which comes from the pouring forth and diffusion of the thoughts and affections from which speech flows, in accordance with the form of heaven, and all affiliation and all communication in heaven is in accordance with that form. That angels are affiliated in accordance with the form of heaven, and that their thoughts and affections flow in accordance with it may be seen above (n. 200-212). {Footnote 1} In angelic speech there is a symphony with harmonious cadence (n. 1648, 1649, 7191). 243. Speech like that in the spiritual world is inherent in every man in his interior intellectual part; but man does not know this, because this speech does not with man, as with angels, fall into words analogous to affection; nevertheless this is what causes man, when he enters the other life, to come into the same speech as spirits and angels, and thus to know how to speak without instruction.{1} But more on this subject hereafter. {Footnote 1} There is spiritual or angelic speech belonging to man, though he does not know it (n. 4104). The ideas of the internal man are spiritual, but during his life in the world man perceives them naturally, because he then thinks in what is natural (n. 10236, 10237, 10551). Man comes after death into his interior ideas (n. 3226, 3342, 3343, 10568, 10604). Those ideas then form his speech (n. 2470-2479). 244. In heaven, as has been said above, all have one speech; but it is varied in this respect, that the speech of the wise is more interior and more full of variations of affections and ideas of thought, while the speech of the less wise is more external and less full; and the speech of the simple is still more external, consisting of words from which the meaning is to be gathered in the same way as when men are talking to one another. There is also speech by the face, terminating in something sonorous modified by ideas. Again, there is speech in which heavenly representatives are mingled with the ideas, and go forth from ideas to sight. There is also speech by gestures that correspond to affections, and represent things like those expressed by their words. There is speech by means of the generals of affections and the generals of thoughts. There is speech like thunder; besides other kinds.
