Plato talked about a second Internal intelligence dwelling within-
Someone who has used his life for learning true wisdom and exercised his higher nature if he finds the truth he cannot fail to attain immortality as completely as human nature allows because he has always nurtured his Divine essence in himself. His Guardian Genius. He is the happiest of people.
Pythagoras a second intelligence in everyone
Father Zeus, free them from their great suffering and show everyone of them the Genius who is their guide.
And we just can't omit Joan of Arc can we?- another gnostic who listened to an inner voice, her second internal intelligence. Her Genius. Her Daemon
Roman Emperor Marcus Aurellius- Two coexisting intelligences again-
Who lives with the Gods? Those who are always satisfied with what has been assigned to them and who obey the prompting of their Genius; a portion of himself that God has given to every human being to be their guide and guardian, their intelligence and understandings.
