Philo was a Jewish philosopher living in Hellenistic Alexandria, Egypt, of the Roman Empire around 20 BCE to 50 CE. He thought of “Logos” [1] along the lines of Plato’s “theory of Ideas” or “theory of Forms” [2]. These are related to panpsychism [3] and the role of archetypes in that consciousness context. For more on that subject, see the post All is Mind.

Philo identified the metaphysical “Logos” with HaShem [4] (an ineffable name of G-d, Hebrew for “the Name”, Tree of Life). Following these connections is one clue connecting the Kabbalistic Tree of Life with a metaphysics of panpsychism and mystical Jewish panentheism [5].

Thanks to the Source. A little more info about Philo:

“Philo visited the Second Temple in Jerusalem at least once in his lifetime.[10] Philo would have been a contemporary of Jesus and his Apostles. Philo along with his brothers received a thorough education. They were educated in the Hellenistic culture of Alexandria and Roman culture, to a degree in Ancient Egyptian culture and particularly in the traditions of Judaism, in the study of Jewish traditional literature and in Greek philosophy.”
