Oxford's All Souls College has a famous fellowship program, access to which is determined by a somewhat infamous exam. What is truly marvelous about this exam, though, is that the questions are profoundly interesting: these are not questions with right and wrong answers, but ones which require deep thought and argument. And that's what's expected of candidates: not an absolute answer to the question, but demonstrating a strong command of the subject, and the ability to make compelling and clear cases.
I have to say that these questions seem quite delightful, and many (all?) of them would make excellent seeds for any conversation. I may well seed posts with them in the future, in fact. Consider some of the following exam questions:
"Did the left or the right win the twentieth century?"
"What, if anything, is wrong with using drones in warfare?"
"When, if ever, should firms bear responsibility for their customers' poor purchasing decisions?"
"Can a privately-supplied currency such as Bitcoin be viable in the long run?"
"How do apologies work?"
"How might we look for the rural poor of the Roman Empire in the archaeological record?"
There are plenty more. This article gives a few, and you can read the complete archive of past questions at http://www.all-souls.ox.ac.uk/content/Past_Papers
Maybe we should have some kind of "All Souls Challenge:" picking questions, writing posts about them and having conversations, and then tagging other victims...
