Avira > what we’re really saying is that to be a gadol beyisroel, one needs to be free of all foreign influence. One must have pure daas torah.
Please define what “free of foreign influence” is and what the source for that is. Was Rambam tainted by secretly reading Aristotle and studying Muslim science? Was Rabban Gamliel tainted by his atrsolobe and having 1000 members of his household studying Greek? Rav Salanter’s son was a mechanical engineer and an inventor and Rav was proud that he was able to re-engineer his son’s invention by seeing the drawings. Is mussar out now?
