Philo considers these divine powers in their totality also, treating them as a single independent being, which he designates "Logos". This name, which he borrowed from Greek philosophy, was first used by Heraclitus and then adopted by the Stoics. Philo's conception of the Logos is influenced by both of these schools. From Heraclitus he borrowed the conception of the "dividing Logos" (λόγος τομεύς), which calls the various objects into existence by the combination of contrasts ("Quis Rerum Divinarum Heres Sit," § 43 503), and from Stoicism, the characterization of the Logos as the active and vivifying power. But Philo borrowed also Platonic elements in designating the Logos as the "idea of ideas" and the "archetypal idea".
