William Boyd at The New Statesman:
I want to start with a luminously beautiful – and luminously profound – quotation from Vladimir Nabokov’s autobiography Speak, Memory. He writes: “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.”
“Common sense”. I believe that the knowledge of this state of affairs is the fundamental truth about our human nature: the fact that our lives simply amount to our individual occupation of this “brief crack of light” between two eternities of darkness shapes everything that makes us human and is responsible for everything good – and everything bad – about us.
You might argue that if you believe in a religious faith, where life and an afterlife are ordained and somehow controlled by a supernatural being – a god or gods – then this awareness of our temporal, bounded existence in time doesn’t apply. In response, you might counter-argue that religious faith is created expressly to confound and disprove this primordial conviction: a faith created, as Philip Larkin put it, to “pretend we never die”.
But whatever the nature of a faith in a supernatural being, or beings, and whatever its unprovable postulates, I am convinced that what makes our species unique among the fauna of this small planet circling its insignificant star is that we know we are trapped in time, caught briefly between these two eternities of darkness, the prenatal darkness and the posthumous one.
