I am generous towards the authors cited (Schiller, Benjamin), and I am unimpressed. Most of these questions constitute the “high middle brow” of intellectual thought: that thought which takes itself too seriously. Is this a recent development at Oxford, or has it always been the case that the university churns out relatively talented but predictably radical students, certainly ones who will not produce anything truly challenging, but whose work will at least seem challenging to those who have not really developed a strong method of inquiry on their own.
I wanted to do a tour of the All Souls College last year but it was closed, unfortunately, on the day I walked by; I was only there for a two day conference and had to leave early the next morning.

Oxford and its equivalent universities around the world (Harvard, Yale, and so on) are not really selecting for radically brilliant views on social or philosophical issues. At the end of the day, it's an institution training elites for business/government/etc. not a fund for intellectual brilliance.
I'm not sure I agree. They're just essay prompts. One could write a bad essay that takes itself too seriously given the prompts, but one could also write a powerful essay starting from any of these prompts. I don't really see where you get the conclusion that students matriculating from these places have recently begun to be smoke-blowers that while possessing detailed knowledge of various arcana fail to produce anything useful.
