A Gentleman in Moscow

by Amor Towles

Luckily, the answer to this conundrum was provided by the philosopher Zeno in the fifth century b.c. Achilles, a man of action and urgency, trained to measure his exertions to the tenth of a second, should be able to quickly dispense with a twenty-yard dash. But in order to advance a yard, the hero must first advance eighteen inches; and in order to advance eighteen inches, he must first advance nine; but to advance nine, he must first advance four and a half, and so on. Thus, on his way to completing the twenty-yard dash, Achilles must traverse an infinite number of lengths—which, by definition, would take an infinite amount of time. By extension (as the Count had liked to point out), the man who has an appointment at twelve has an infinite number of intervals between now and then in which to pursue the satisfactions of the spirit. Quod erat demonstrandum.
