I made a point of answering the question I received with some frequency from journalists, Do you think books can change people's lives? (which really meant, Do you actually think anything you could write could mean anything to anyone?), with a little airtight thought experiment in which I asked the interviewer to imagine the sort of person he might be if all of the literature he'd read in his life were somehow excised from his mind, his mind and soul, and as the journalist contemplated this nuclear winter I sat back with a self-satisfied smile, saved again from facing the truth.
