“Memories can be vile. Repulsive little brutes, like children I suppose. But can we live without them? Memories are what our reason is based upon. If we can't face them, we deny reason itself! Although, why not? We aren't contractually tied down to rationality. There is no sanity clause. So when you find yourself locked down in an unpleasant train of thought, heading for the places in your past where the screaming is unbearable, remember: There's always madness. You can just step outside and close the door, and all those dreadful things that happened, you can lock them away. Madness... is an emergency exit.”
