Tell me, Genry, what is known? What is sure, predictable, inevitable—the one certain thing you know concerning your future, and mine?
—That we shall die.
Yes. There’s really only one question that can be answered, Genry, and we already know the answer. (…) The only thing that makes life possible is permanent, intolerable uncertainty: not knowing what comes next.
