This is a time of saviours. Just as ideological crises in slave-holding civilisations a few centuries back produced Jesus, Mohammed, and other extraordinary individuals, so the crises of the 21st Century will throw up individuals, and moments in individuals, of extraordinary power, dynamism, selflessness and wisdom. Let us get ready for these saviours, but not rely on them. Ultimately they can only guide by example. We are all responsible for ourselves. We are all called upon to be saviours, even if just for a few moments, whenever we can.
