I have great faith in optimism as a guiding principle, if only because it offers us the opportunity of creating a self-fulfilling prophecy. So I hope we've learnt something from the most barbaric century in history -- the 20th. I would like to see us overcome our tribal divisions and begin to think and act as if we were one family. That would be real globalisation.
