We later civilizations . . . we too know that we are mortal.— Paul Valéry
We had long heard tell of whole worlds that had vanished, of empires sunk without a trace, gone down with all their men and all their machines into the unexplorable depths of the centuries, with their gods and their laws, their academies and their sciences pure and applied, their grammars and their dictionaries, their Classics, their Romantics, and their Symbolists, their critics and the critics of their critics. We were aware that the visible earth is made of ashes, and that ashes signify something. Through the obscure depths of history we could make out the phantoms of great ships laden with riches and intellect; we could not count them. But the disasters that had sent them down were, after all, none of our affair.
Elam, Ninevah, Babylon were but beautiful vague names, and the total ruin of those worlds had as little significance for us as their very existence. But France, England, Russia…these too would be beautiful names. Lusitania too, is a beautiful name. And we see now that the abyss of history is deep enough to hold us all. We are aware that a civilization has the same fragility as a life. The circumstances that could send the works of Keats and Baudelaire to join the works of Menander are no longer inconceivable; they are in the newspapers.
That is not all. The searing lesson is more complete still. It was not enough for our generation to learn from its own experience how the most beautiful things and the most ancient, the most formidable and the best ordered, can perish by accident; in the realm of thought, feeling, and common sense, we witnessed extraordinary phenomena: paradox suddenly become fact, and obvious fact brutally belied.
