“The point is that if you think you can pinpoint the cause, then you can fool yourself into thinking you can avert the cause. It's deeply egotistical. It's life played as a grand insurance policy. Our myth-making around cancer stems from the same impulse. Because we don't know exactly why most of it happens, we weave a makeshift wisdom around it, a false prophet, which seeps into the common story and feeds our hunger to understand why. The guilt is a byproduct, a way to assign blame and seek absolution. It's a lesser evil than the forces of randomness. And it gives us the illusion of control.”
