First let us sympathise, if only for an instant, with the hopes of the Dickens period, with that cheerful trouble of change. If democracy has disappointed you, do not think of it as a burst bubble, but at least as a broken heart, an old love-affair. Do not sneer at the time when the creed of humanity was on its honeymoon; treat it with the dreadful reverence that is due to youth. For you, perhaps, a drearier philosophy has covered and eclipsed the earth. The fierce poet of the Middle Ages wrote, "Abandon hope, all ye who enter here," over the gates of the lower world. The emancipated poets of to-day have written it over the gates of this world. But if we are to understand the story which follows, we must erase that apocalyptic writing, if only for an hour. We must recreate the faith of our fathers, if only as an artistic atmosphere. If, then, you are a pessimist, in reading this story, forego for a little the pleasures of pessimism. Dream for one mad moment that the grass is green. Unlearn that sinister learning that you think so clear; deny that deadly knowledge that you think you know. Surrender the very flower of your culture; give up the very jewel of your pride; abandon hopelessness, all ye who enter here.
-Charles Dickens (1906)
