"I suspect that some of you would say ‘A civilized nation is one that has railways, modern industry, organized army, tank, aircraft, etc., and an uncivilized nation is one that does not possess such things.’ Or you would say that a civilized nation is one whose cities ... have wide and paved streets, with multi-storey buildings, and so on.’ Civilized nations, of course, do have such things, but I submit that these are products of civilization, not its essence. The essence of civilization is that people are mature, and the clearest sign of their maturity is that they observe the law."
