Disaster movies tend to follow a similar arc. Our band of heroes not only has to survive flames engulfing the skyscraper or sea water flooding the cruise liner, but must also triumph over the calculated selfishness of others who are also scrambling for salvation. The implication is that, with few exceptions, Thomas Hobbes was right. Amid the upheaval of the English Civil War, Hobbes declared that our natural human condition is a war of all against all, and that order can only be secured by a powerful ruler, a Leviathan, that keeps our naked urges in check. The social contract of considerate behaviour and thoughtfulness towards others is a thin veneer. Under pressure it peels away, and we are soon at one another’s throats in a life that is solitary, poor, nasty, brutish, and short.
