CS > When people study a secular course on a topic, they become arrogant as they feel themselves a master of the subject, whereas when one learns Torah, the more they learn, the more humble they become
this is a gut vort. One hiluk: when Rabonim from 50-200 years ago write about this, it is about people who are abandoning Torah in favor of secular culture and knowledge. We here are mostly discussing Torah-observant Yidden adding knowledge of science or professions. This is a different issue.
Just to ponder: when gemora says – ein Torah b’goyim aval yesh Chochma b’goyim, why do they put these 2 things nearby, and how do they know about Chochma b’goyim? learned it and compared with their own studies?
