3047. On the nature of evil spirits
The wickedness and deceitful nature of inward evil spirits is indescribable. For the least bit of thought that a person can ever discern, when it is good,* they so skilfully turn into evil, that it is hardly imaginable. Nor are they only so malicious as to turn good into evil, as soon as it appears, but there are also those who, when they so to speak smell that good is going to come of it, immediately turn that [into evil]. * The original has homo, I believe, for bonum.
