Build a man a fire, and he'll be warm for a day. Set a man on fire, and he'll be warm for the rest of his life. -Terry Pratchett.
Tell a man there are 300 billion stars in the universe and he'll believe you. Tell him a bench has wet paint on it and he'll have to touch to be sure.
If kindness and comfort are, as I suspect, the results of an energy surplus, then, as the supply contracts, we could be expected to start fighting once again like cats in a sack. -George Monbiot
