Daimon is the Greek derivative for the term demon. In this sense the term “demon” means “replete with knowledge.” The ancient Greeks thought there were good and bad demons called ‘eudemons’ and ‘cacodemons.’ The term ‘daimon’ means “divine power,” “fate” or “god.”
Daimons, in Greek mythology, included deified heroes. They were considered intermediary spirits between men and the gods. Good daimons were considered to be guardian spirits, giving guidance and protection to the ones they watched over. Bad daimons led people astray.
Socrates said he had a life-time daimon that always warned him of danger and bad judgment, but never directed his actions.
