Final answer:
Philo of Alexandria greatly impacted Hellenistic philosophies with his fusion of Greek and Jewish philosophy, serving as a mediator between God and the physical world.
Step-by-step explanation:
Philo of Alexandria greatly impacted Hellenistic philosophies with his fusion of Greek and Jewish philosophy. Philo used the ideas developed by Plato and other Greek philosophers to explain and justify Jewish scripture. In his work, he identified Plato's forms as 'logos', which served as the mediator between God and the physical world. This fusion of Greek and Jewish philosophy laid the foundation for early Christian doctrine.
