I'm not sure philosophers debating is a useful signal about whether an issue is settled. I'm having a hard time thinking of a topic on which philosophers would not debate.
What conventional terrorism technique have I used? Here's an analogue of what happened.
Bob says: yeah it's pretty easy to see that every even integer greater than 2 can be expressed as the sum of two primes.[1]
I say: not so fast, you can't just claim things like that. I mean it might be intuitive or 'generally accepted' (and even stochastically probable!), but the truth-value of such a statement is difficult to prove.
And the philosophical debate is far from over; it is ongoing: http://plato.stanford.edu/entries/torture/ Reading some of the literature can be quite fascinating.
Ouch, the down-votes :(
