On January 18, 1915, six months into the First World War, as all Europe was convulsed by killing and dying, Virginia Woolf wrote in her journal, 'The future is dark, which is on the whole, the best thing the future can be, I think.' Dark, she seems to be saying, as in inscrutable, not as in terrible. We often mistake the one for the other. Or we transform the future's unknowability into something certain, the fulfillment of all our dread, the place beyond which there is no way forward. Be again and again, far stranger things happen than the end of the world.
