"In
this respect, our townsfolk were like everybody else, wrapped up in themselves;
in other words, they were humanists: They disbelieved in pestilences. A
pestilence isn't a thing made to man's measure; therefore we tell ourselves
that pestilence is a mere bogy of the mind, a bad dream that will pass away.
But it doesn't always pass away and, from one bad dream to another, it is men
who pass away."
-Albert Camus, The Plague
