Which City Do You Live In?

"They say that every time they go below they find something has changed in the lower Eusapia; the dead make innovations in their city; not many, but surely the fruit of sober reflection, not passing whims. From one year to the next, they say, the Eusapia of the dead becomes unrecognizable. And the living, to keep up with them, also want to do everything that the hooded brothers tell them about the novelties of the dead. So the Eusapia of the living has taken to copying its underground copy.

They say that this has not just now begun to happen: actually it was the dead who built the upper Eusapia, in the image of their city. They say that in the twin cities there is no longer any way of knowing who is alive and who is dead."
