Some turn good into evil by deceit, some because of different passions, so there are many causes. But here I am allowed to mention only one way in which goodness in spirits is turned into evil, without their hardly realizing it, as in the case of those who had become sick of their wives, and thereby felt almost disgust [for them], and thus for marriage love. When any delight or pleasantness pertaining to marriage love reaches them, because they had grown sick of it, that pleasantness and delight is turned with them at once into boredom and aversion, and thus into the opposite. I spoke with spirits about this, for the same thing is true of other enjoyments and delights. 1748, 18 May.
