Take this picture I posted earlier: "Charity admonishes demons representing ‘knowledge without love’ which does no good, but ‘inflates man with an empty windiness’.”
The maker of this doesn't think that every person he meets who likes to stroke his own ego with his knowledge of facts is a demon, he just wants to point out that you should beware of this pitfall because it makes you a dick and won't lead to true wisdom. On the other hand, it is the Devil who is trying to make you think that this is an okay way of thinking/being. You need a lot of self-awareness to separate the bad/evil thoughts from the good/godly thoughts. The only way to exorcise demons like these is to genuinely try to be a good person. Your own bad qualities are the demons but they're also really demons.

Also they had a very different idea of knowledge in the Middle Ages which is an extremely interesting topic I'm totally not equipped to talk about. Anna Wierzbicka wrote a wonderful book on the etymology of the word 'evidence' and how it evolved along with the ideas about knowledge from the Middle Ages to modern times.
