Philo of Alexandria is a thinker who defies taxonomy. The taxonomists in religious studies class him as a “Jewish philosopher,” implying that both his Judaism and his philosophy are paramount to his identity, yet his “philosophy” seems almost non-rational, and his Judaism non-traditional at best. I suggest that the best way to understand Philo’s writings and motivations is to loosen the modern attempt at classification and try to apprehend him on his own terms.
