As someone who pretty much fits the mold of the college student who skated past math and the sciences, it's hard to disagree with his assessment and this passage stung:
Intellectuals and academics are just assumed to have some background knowledge of the arts, and not knowing those things can count against you. Ignorance of math and science is no obstacle, though. I have seen tenured professors of the humanities say — in public faculty discussions, no less — “I’m just no good at math,” without a trace of shame. There is absolutely no expectation that Intellectuals know even basic math.
