Sorry for my prolonged silence. I recently started work after a lengthy spell of unemployment and the upheaval involved has left little time for philosophy. Hopefully, once I've adjusted to the new regime I'll be back on the case (albeit at a slower pace).
The job is exactly the sort of thing Wittgenstein would have approved of: factory-fodder. He was always advising his students to avoid academia and do something "useful" instead. This only goes to show that sometimes even the greatest minds can be a bit stupid.
