The problem with telling the truth is that much of what happens in the world is made possible by lies, and so much of the world is actively opposed to truth. We might respond to this with the great ‘So what!’ of modern culture: maybe the world doesn’t need truth, maybe the world is just fine as it is. When I write, I like to remind myself of exactly why it is I’m writing.
