3335. Today and yesterday I had a perception of the sphere incredulity, to wit, that [such spirits] wish to believe nothing of those things which were said and seen, when I arranged those things which were seen under their general heads. In the world these are commonly styled skeptics, because they believe nothing; nor will they believe aught that is said concerning the other life, nor concerning spheres. There are many of such a character, and they derive from phantasies, that they wish to believe nothing but what they see, or apprehend by the senses, -wherefore, so long as they are in such credulity, they believe nothing.
