We live in a world where all things, good and bad, are finally destroyed by change. The world sustains us, it would seem, only to devour us at its leisure. Parents lose their children and children their parents. Husbands and wives are separated in an instant, never to meet again. Friends part company in haste, without knowing that it will be for the last time. This life, when surveyed with a broad glance, presents little more than a vast spectacle of loss.
But it seems that there is a cure for all this. If we live rightly—not necessarily ethically, but within the framework of certain ancient beliefs and stereotyped behaviors—we will get everything we want after we die. When our bodies finally fail us, we just shed our corporeal ballast and travel to a land where we are reunited with everyone we loved while alive. Of course, overly rational people and other rabble will be kept out of this happy place, and those who suspended their disbelief while alive will be free to enjoy themselves for all eternity.
Sam Harris, The End of Faith
