" A microscopic egg had failed to divide in time due to a failure somewhere along a chain of chemical events, a tiny disturbance in a cascade of protein reactions. A molecular event ballooned like an exploding universe, out onto the wider scale of human misery. No cruelty, nothing avenged, no ghost moving in mysterious ways. Merely a gene transcribed in error, an enzyme recipe skewed, a chemical bond severed. A process of natural wastage as indifferent as it was pointless. Which only brought into relief healthy, perfectly formed life, equally contingent, equally without purpose. Blind luck, to arrive in the world with your properly formed parts in the right place, to be born to parents who were loving, not cruel, or to escape, by geographical or social accident, war or poverty. And therefore to find it so much easier to be virtuous. "

― Ian McEwan , The Children Act
