Rabbi Kalonimus Kalman Szapiro and the Stoics

I’m in a class learning parts of Rabbi Shapira’s work, and my study partner and I recently discussed whether R’ Shapira was influenced by the Stoics. I am not as well-versed in the Greeks as my partner; there’s nothing evident in our materials to say if he was consciously in line with the Stoics, or just happened to come to similar conclusions, perhaps having learned from rabbis (who learned from rabbis, who learned from . . .) who did make a point of studying the Stoics.

So, does anyone have insight into R’ Shapira’s influences, with regard to Stoic thought?
