We talk of Plato or the Parthenon or the Greek passion for beauty as parts of the antique, but hardly of the antiquated. When we call them ancient it is not because they have perished, but rather because they have survived. In the same way I heard some New Yorkers refer to Philadelphia or Baltimore as ‘dead towns.’ They mean by a dead town a town that has had the impudence not to die. Such people are astonished to find an ancient thing alive, just as they are now astonished, and will be increasingly astonished, to find Poland or the Papacy or the French nation still alive. And what I mean by Philadelphia and Baltimore being alive is precisely what these people mean by their being dead; it is continuity; it is the presence of the life first breathed into them and of the purpose of their being; it is the benediction of the founders of the colonies and the fathers of the republic. This tradition is truly to be called life; for life alone can link the past and the future. It merely means that as what was done yesterday makes some difference to-day, so what is done to-day will make some difference to-morrow. In New York it is difficult to feel that any day will make any difference. These moderns only die daily without power to rise from the dead.
