Seneca on the Shortness of Life
The De Brevitate Vitae — On the Shortness of Life — was written by Seneca in his middle years, addressed to his friend Paulinus, who managed Rome's grain supply. The essay's opening sentence is one of the most quoted in all of Latin philosophy, and one of the most misunderstood.
It is not that we have a short time to live, Seneca writes, but that we waste much of it. Life is long if you know how to use it. We are not given a short life, but we make it short, and we are not ill-supplied but wasteful of it. The complaint of the brevity of life is the complaint of the spendthrift about the brevity of money.
The Latin is sharper than translation suggests. Seneca's argument is not the pop-philosophy line that one should live every moment to the fullest. It is closer to an accounting. He thinks of time as a wealth that we squander because we do not see its expenditure clearly. The man who would never let a slave pour out a flagon of his best wine will allow whole years to pour out into nothing — into politics he does not care about, gossip he will not remember, obligations that bring no honor and no growth.
He is hard on certain types. The man perpetually too busy — Seneca calls him the occupatus, the occupied one — has a particular kind of poverty. He owns time but never inhabits it. He defers life to a future that he will not actually reach, because his disposition is to defer. When retirement comes, if it ever comes, he will have lost the capacity to be present that he refused to practice in middle age. The longest life, badly lived, can be the shortest.
Seneca's recommendation is not new and is not surprising. Spend time on what actually matters to you. Cut what does not. Read difficult books, because they are conversations with minds better than yours, and they are cheap by the standard of the time they save you compared to discovering the same things alone. Cultivate the few friendships that survive examination. Notice when you are being driven by other people's expectations and decide whether you accept them.
What is striking is the texture of Seneca's account of why we do not do this. He thinks the failure is rarely from ignorance. We know what is worth our time. We know which conversations are wasted. We know that the third hour of scrolling produced nothing the first hour did not. The failure is from the same kind of inertia that lets people stay in jobs they hate or marriages they have already left in spirit. The cost of changing course is paid up front; the benefit accumulates slowly. The brain prefers the cheap, certain present to the expensive, uncertain future.
There is a darker thread running through Seneca's work, which has caused some readers to dismiss him. He himself was rich, politically entangled, and ultimately the tutor and advisor of the emperor Nero — under whose orders he was eventually forced to commit suicide. The man writing about the shortness of life spent enormous amounts of his own life in the service of a regime that grew steadily more monstrous. Did he take his own advice? Probably not, in the way he formulated it.
But this is also a reason to take his writing seriously. Seneca was not writing as a man who had solved the problem. He was writing as a man who could see the problem clearly and had failed to escape it. The De Brevitate Vitae has the texture of a self-rebuke as much as an exhortation. The man who is hardest on the occupatus knew exactly who that man was.
