Spirits of Jupiter are with me and are very surprised that I am able to write the ideas of their thought in this way (for they have guided previously, as also today, the things I have written about them). And this was because when granted reflection [on the matter], they had reported to others, who were also surprised, that this could be done, suggesting to them that the inhabitants of this planet are able to be educated in this way, and whoever reads, to learn. This I perceived from their thought, and no speaking, from which thought, or perception of their thought I have written these words, they also desiring to affirm this by a still more subtle perception. 1748, 3 Sept.
