"Our pretense is a dedication. Someone must appear to believe. Our lives are no less serious than if we professed real faith, real belief. As belief shrinks from the world, people find it more necessary than ever that someone believe. Wild-eyed men in caves. Nuns in black. Monks who do not speak. We are left to believe. Fools, children. Those who have abandoned belief must still believe in us. They are sure that they are right not to believe but they know belief must not fade completely. Hell is when no one believes. There must always be believers. Fools, idiots, those who hear voices, those who speak in tongues. We are your lunatics. We surrender our lives to make your nonbelief possible. You are sure that you are right but you don't want everyone to think as you do. There is no truth without fools. We are your fools, your madwomen, rising at dawn to pray, lighting candles, asking statues for good health, long life."
This is quite a good read, not as good as Underground, but at 1/3 the length… Check it out: White Noise, by Dan DeLlilo
