In Tom Stoppard's The Hard Problem, Hilary is a young psychology researcher at the Krohl Institute for Brain Science, where psychology and biology meet. If there is nothing but matter, what is consciousness? This is "the hard problem" facing science, and for Hilary the possibility of genuine altruism, without a hidden Darwinian self-interest, depends on the answer. Meanwhile, she is nursing a private sorrow. She needs a miracle and is prepared to pray for one.
