The Eighteenth Hour

Ben Franklin observes the brief life of a fly.

Madame Brillon,

You may remember, my dear friend, that when we lately spent that happy day in the delightful garden and sweet society of the Moulin Joly, I stopped a little in one of our walks and stayed some time behind the company. We had been shown numberless skeletons of a kind of little fly called an ephemera, whose successive generations, we were told, were bred and expired within the day. I happened to see a living company of them on a leaf, who appeared to be engaged in conversation. You know I understand all the inferior animal tongues. I listened through curiosity to the discourse of these little creatures, but as they, in their natural vivacity, spoke three or four together, I could make but little of their conversation. I found, however, by some broken expressions that I heard now and then, they were disputing warmly on the merit of two foreign musicians—one a cousin and the other a moscheto—in which dispute they spent their time, seemingly as regardless of the shortness of life as if they had been sure of living a month. Happy people! thought I, you live certainly under a wise, just, and mild government, since you have no public grievances to complain of, nor any subject of contention but the perfections and imperfections of foreign music. I turned my head from them to an old gray-headed one, who was single, on another leaf, and talking to himself. Being amused with his soliloquy, I put it down in writing,

“It was,” said he, “the opinion of learned philosophers of our race, who lived and flourished long before my time, that this vast world, the Moulin Joly, could not itself subsist more than eighteen hours; and I think there was some foundation for that opinion, since, by the apparent motion of the great luminary that gives life to all nature, and which in my time has evidently declined considerably toward the ocean at the end of our earth, it must then finish its course, be extinguished in the waters that surround us, and leave the world in cold and darkness, necessarily producing universal death and destruction. I have lived seven of those hours, a great age, being no less than four hundred and twenty minutes of time. How very few of us continue so long! I have seen generations born, flourish, and expire. My present friends are the children and grandchildren of the friends of my youth, who are now, alas, no more! And I must soon follow them, for by the course of nature, though still in health, I cannot expect to live above seven or eight minutes longer. What now avails all my toil and labor, in amassing honeydew on this leaf, which I cannot live to enjoy! What the political struggles I have been engaged in for the good of my compatriot inhabitants of this bush, or my philosophical studies for the benefit of our race in general! For, in politics, what can laws do without morals? Our present race of ephemeras will in the course of minutes become corrupt, like those of other and older bushes, and consequently as wretched. And in philosophy how small our progress! Alas! Art is long, and life is short! My friends would comfort me with the idea of a name, they say, I shall leave behind me, and they tell me I have lived long enough to nature and to glory. But what will fame be to an ephemera who no longer exists? And what will become of all history in the eighteenth hour, when the world itself, even the whole Moulin Joly, shall come to its end and be buried in universal ruin?”

To me, after all my eager pursuits, no solid pleasures now remain, but the reflection of a long life spent in meaning well, the sensible conversation of a few good lady ephemeras, and now and then a kind smile and a tune from the ever amiable Brilliante

Benjamin Franklin

From a letter. Born in 1706, the tenth of seventeen children, Franklin quit school at the age of ten and became an apprentice printer two years later. He settled in Philadelphia in 1726, printing the state’s currency in 1730 and beginning to publish Poor Richard’s almanac in 1732. Franklin invented the lightning rod, bifocal glasses, and the odometer; he created charts of the Gulf Stream and devised theories about how the common cold spread. He died at the age of eighty-four in 1790.
