St. Anthony tormented by demons
by Martin Schongauer ~1480s
n his book Demon Haunted World Carl Sagan claims that the word "demon" comes from the Greek word for "knowledge" yet in looking around the internet to verify this I am unable. Some explanations make more sense than others. I would think it logical that it somehow has a root in common with the word "Deity" say in the Greek word "deiwos" that originally meant a shining or bright light. But how does this then translate to knowledge? Does anyone out there know the source Carl Sagan used to claim that the word demon comes from the Greek word for knowledge?
