What gives meaning to a life? Kierkegaard opted for belief. He wrote:
If there were no eternal consciousness in a man, if at the foundation of all there lay only a wildly seething power which writhing with obscure passions produced everything that is great and everything that is insignificant, if a bottomless void never satiated lay hidden beneath all -- what then would life be but despair?This is the fear that caused Abraham to raise the knife over his beloved son. This is the valley of shadow that drove Kierkegaard to choose heaven over earth, the unseen over the seen. This is the dread of a mindless oblivion that causes so many to choose faith over reason, certainity over doubt.
In Fear and Trembling, Kierkegaard says that "faith begins where thinking leaves off." At the same age, Kierkegaard's almost exact contemporary, another solitary philosopher with a fierce moral sensitivity, Henry David Thoreau, wrote in his journal:
I have just heard the flicker among the oaks on the hillside ushering in a new dynasty...Eternity could not begin with more security and momentousness than the spring. The summer's eternity is reestablished by this note. All sights and sounds are seen and heard both in time and eternity. And when the eternity of any sight or sound strikes the eye or ear, they are intoxicated with delight.Some of us live our lives with our attention fixed on the hereafter. Others listen for the flicker's note in the distant oaks. No less than traditional theists, religious naturalists need to believe that we are not poised above a bottomless void. If we are lucky, we understand that love and loyalty are blessings that well up out of the dark night in mysterious ways. We feel no need to make the terrible journey to Mount Moriah when every element of creation, great and small, here and now, is filled with redeeming grace.
