YYA, when you are talking about philosophy, I won’t argue much with that. I am not pro or contra. As I said, I’d be happy to see Jewish community absorb first non-controversial ideas of modernity while arguing about philosophy. R Twersky suggests in some speech that yeshiva bochrim should learn physiology to appreciate maase Hashem, and then adds – doesn’t have to be at school, do it after school. Realistically speaking, if we want community to absorb ideas, it got to be in school or some other institutions.
The reason to learn from Western civilization v. Hindu is pretty simple – Western civilization is tremendously successful in the last several hundred years changing lives of billions of people. We all use fruits of that.
