" Think of the epidemics that wiped out ten, twenty, even thirty percent of populations in Europe: I read somewhere recently that the city of Leiden lost thirty-five percent of its population in a five-year period in the 1630s. What could it mean to live with such a possibility, with people of all ages dropping dead around you all the time? The thing is that we have no idea. In fact, when I read it, it was as a footnote in an article talking about something else, an article about painting or furniture.
Families that lost three of their seven members were not at all unusual. For us, the concept of three million New Yorkers dead from illness within the first five years of the millennium is impossible to grasp. We think it would be total dystopia; so, we think of such historical realities only as footnotes. We try to forget that other cities in other times have seen worse, that there isn’t anything that immunizes us from a plague of one kind or another, that we are just as susceptible as any of those past civilizations were, but we are especially unready for it. Even in the way we speak about what little has happened to us, we have already exhausted ourselves with hyperbole. "
