So….by har sinai there was a mesorah that Hashem is only giving us religious things but we need perfection from elsewhere?
Hashem said at har sinai “today you are a people to me,” because of this Torah you are a nation – founded in the desert, not in eretz yisroel; Modern Orthodoxy believes in nationalism, that we’re a nation because of the Torah “and” language, fraternity, land, etc…see the theme? Torah isn’t enough for them.
And why isn’t Torah enough? Because “if it is empty, it is from you,” chazal say if one finds torah deficient, it is because he is the empty one. He isn’t giving Torah enough dedication and effort, so he turns to things which are easier, like science and literature, and then fools himself into thinking he’s bigger than talmidei chachamim.
