I fear no hell, just as I expect no heaven. Nabokov summed up a nonbeliever’s view of the cosmos, and our place in it, thus: “The cradle rocks above an abyss, and common sense tells us that our existence is but a brief crack of light between two eternities of darkness.” The 19th-century Scottish historian Thomas Carlyle put it slightly differently: “One life. A little gleam of Time between two Eternities.” Though I have many memories to cherish, I value the present, my time on earth, those around me now. I miss those who have departed, and recognize, painful as it is, that I will never be reunited with them. There is the here and now – no more. But certainly no less. Being an adult means, as Orwell put it, having the “power of facing unpleasant facts.” True adulthood begins with doing just that, with renouncing comforting fables. There is something liberating in recognizing ourselves as mammals with some fourscore years (if we’re lucky) to make the most of on this earth. There is also something intrinsically courageous about being an atheist. Atheists confront death without mythology or sugarcoating. That takes courage.
