Again, Christianity asserts that every individual human being is going to live for ever, and this must be either true or false. . . . And immortality makes this other difference, which, by the by, has a connection with the difference between totalitarianism and democracy. If individuals live only seventy years, then a state, or a nation, or a civilisation, which may last for a thousand years, is more important than an individual. But if Christianity is true, then the individual is not only more important but incomparably more important, for he is everlasting and the life of the state or civilisation, compared with his, is only a moment.
— C.S. Lewis, Mere Christianity 74-75
