By means of a spiritual mental image I saw, and was allowed to share with spirits, that the mental images of those who do not want to believe unless they know and understand are formed from innumerable ones of those who reason falsely about every object of sight. For the urge of spirits is such that, thinking they know everything, they reason about everything, some even from conviction, when yet it is a false one. These innumerable images merge in every single one belonging to those who do not want to believe unless they understand, so that if that mental image formed from all those images were presented before the eyes, by portraying a face, or some other thing, they would be so filthy and ugly, that there never could be anything filthier and uglier, 1748, 14 Sept. This I saw by a spiritual mental image, together with the spirits around me. One spirit told that he had seen a mental image displayed to him, of someone, not so evil, saying that he had never seen an uglier one, 1748, 14 Sept., and it was only a general mental image, so faint as to be none at all. Another said only that he had not believed it possible for such things to be seen in the other life-his mental image being at once portrayed, which surpassed the others in ugliness. 1748, 14 Sept.
