A man who makes his golf or his motor-bicycle the centre of his life, or a woman who devotes all her thoughts to clothes or bridge or her dog, is being just as "intemperate" as someone who gets drunk every evening. Of course, it does not show on the outside so easily: bridge-mania or golf-mania do not make you fall down in the middle of the road. But God is not deceived by externals.
C.S. Lewis, Mere Christianity, p. 76
