Final answer:
The query does not align with the provided texts about Philo, Favorinus, and ancient Greek philosophy, hence, a direct answer to whom Phileros refers to when he mentions 'the living' cannot be provided without additional context.
Step-by-step explanation:
The question, when Phileros says, "Let's think of the living", whom does he proceed to talk about, does not directly relate to any provided text on Philo, Favorinus, or ancient Greek philosophy. The information given focuses on philosophical interpretations of eternal life, the blending of Greek and Jewish philosophies, early Jewish philosophy, and ancient Greek views on life after death.
It suggests the philosophical inquiry into the nature of existence and the relationship between the divine and the physical world, notably through the work of Philo of Alexandria who utilized Greek philosophical ideas to interpret Jewish scriptures, in particular the concept of logos.
However, without a specific text referencing Phileros, it's not possible to answer precisely whom he talks about when he mentions "the living".
