Avi, i realize that’s how Wikipedia writes about “Jewish scholars”, but besides implicit “proof” such as the aforementioned shvil hazahav, where do we find that chachamim were so readily open to reading every apikores’ book? When one is into hashkofa, there will be overlaps and coincidences.
Who thought that Rav Shlomo ibn Gavirol was not Jewish? An academic? Seriously, we know of him from the piyutim that he wrote, all of which were in prestine lashon kodesh.
Like I said, the amount of rishonim who eschewed philosophy is great. The Rashba banned any and all non Jewish literature, to name but one source. Many rabbis who lived during the time of the rishonim were not necessarily gedolei yisroel; I’d refer you once again to “Torah Chazal and science” by Rabbi Moshe Meiselman for a lot of researched detail on that subject.
