Cratippus of Pergamon (Ancient Greek: Κράτιππος), was a leading Peripatetic philosopher of the 1st century BC who taught at Mytilene and Athens.
[2] Cratippus lived for a time at Mytilene, and accompanied Pompey in his flight after the Battle of Pharsalia, endeavouring to comfort and rouse him by philosophical arguments.
[5] When Julius Caesar was at the head of the Roman republic, Cicero obtained from him Roman citizenship for Cratippus, and also induced the council of the Areopagus at Athens to invite the philosopher to remain in the city and to continue his instructions in philosophy.
Cicero states that Cratippus believed in dreams and supernatural inspiration (Latin: furor) but that he rejected all other kinds of divination.
[10] He seems to have held that, while motion, sense and appetite cannot exist apart from the body, thought reaches its greatest power when most free from bodily influence, and that divination is due to the direct action of the divine mind on that part of the human soul which is not dependent on the body.
