Ok, wow. First of all, I refuse to rate philosophy classics. It's not my job to determine if they're good or not.
Weil is certainly not a conventional existentialist, she seems to definitely have an idea of a kind of Kantian noumenon, in "truth", as well as "beauty". She also really hates socialism, mainly she doesn't seem to understand that social equality (which she likes. Kind of?) requires material equality. Anyway, a piece of work.
