Jewish appropriationism...?

Due to a flight cancellation (again... ) I had to spend 3 hours at the Oslo airport last night. Hence I went to the bookstore (what else can you do at an airport...) to have a look at the books. I found one I hadn't seen before by
David Biale, Cultures of the Jews. Vol. One: Mediterranean Origins (Schocken Books, New York). It contains, inter alia, an article by Erich S Gruen on Hellenistic Judaism (77-132), and one by Eric M. Meyers on Jewish Culture in Greco-Roman Palestine (pp. 135-179).

I read the article by Gruen, and especially noted the final words of that articlep. 124: “Jews thoroughly embraced the Diaspora communities in which they could lead full and rewarding lives - without compromising their allegiance to the symbol of their faith in Jerusalem. They successfully negotiated their own place within the world of Greco-Roman Society: they were appropriationists rather than assimilationists. And they shunned the melting pot.” Would not this also be a fitting description of Philo's attitudes to the Greco-Roman culture?
