This letter begins with one of Seneca’s funniest stories: a short boat trip, a miserable bout of seasickness, and Seneca jumping overboard in his cloak to swim for shore. From there he draws a serious lesson. We notice bodily illness eventually, but the sicker the soul, the less it knows it’s sick. Only philosophy can wake us up, and it won’t accept our leftover time. “Only someone who is awake can tell his dream.”
From Seneca to Lucilius
You can talk me into almost anything now, because I was recently talked into traveling by sea. We set out when the sea was lazily smooth. The sky, it’s true, was heavy with ugly clouds, the kind that usually turn into rain or squalls. Still, I figured the few miles between Puteoli and your beloved Parthenope could be covered quickly, despite the uncertain, threatening sky. So, to get there faster, I headed straight out to sea toward Nesis, meaning to cut across all the bays.
Seasick and Overboard
But when we were so far out that it made little difference whether I turned back or kept going, the calm that had lured me out vanished. The storm hadn’t started yet, but the swell had, and the waves kept coming faster and faster. I began asking the pilot to put me ashore somewhere. He replied that the coast was rough and a bad place to land, and that in a storm there was nothing he feared more than a shore. But I was suffering too much to think about danger, since a sluggish seasickness with no relief was tormenting me, the kind that upsets the stomach without emptying it. So I laid down the law to my pilot and made him head for the shore, whether he liked it or not.
When we got close, I didn’t wait for things to be done the way Vergil orders, until
the prow turned to the sea
or
the anchor dropped from the bow;
I remembered my calling as a veteran cold-water swimmer, and, dressed as I was in my cloak, I let myself down into the sea, just as a cold-water bather should.
What do you think I felt like, scrambling over the rocks, hunting for the path or making one myself? I understood that sailors have good reason to fear the land. You wouldn’t believe what I went through when I couldn’t bear myself. Take it from me: the reason Ulysses was shipwrecked at every turn wasn’t so much that the sea god had been angry with him since birth. He simply got seasick. And from now on, if I ever have to go anywhere by sea, I’ll reach my destination in the twentieth year.
The Illnesses We Ignore
When I finally settled my stomach (you know you don’t escape seasickness just by escaping the sea) and revived my body with a rubdown, I began to think about how completely we forget or ignore our failings, even those of the body, which keep reminding us they exist, to say nothing of those that are more serious the more hidden they are.
A slight chill fools us. But when it grows and a real fever starts to burn, it forces even a tough man who can bear a lot of suffering to admit he’s sick. There’s pain in the foot and a tingling in the joints, but we still hide the problem and announce that we’ve twisted an ankle or are tired from too much exercise. Then the illness, uncertain at first, has to be given a name; and when it starts to swell the ankles too, and has made both our feet into “right” feet, we’re forced to admit we have gout.
The Deeper the Sleep, the Fewer the Dreams
The opposite is true of diseases of the soul: the worse it is, the less you notice it. Don’t be surprised, my dear Lucilius. Someone who sleeps lightly chases visions in his sleep, and sometimes, though asleep, knows that he’s sleeping. But deep sleep wipes out even our dreams and sinks the spirit so low that it has no awareness of itself.
Why does no one confess his faults? Because he’s still in their grip. Only someone who is awake can tell his dream, and in the same way, admitting your faults is a sign of a healthy mind.
Give Philosophy Your Whole Self
So let’s wake ourselves up, so we can correct our mistakes. But philosophy is the only power that can rouse us, the only power that can shake off our deep sleep. Devote yourself completely to philosophy. You’re worthy of her; she’s worthy of you; embrace each other warmly. Say goodbye to all your other pursuits, bravely and openly. Don’t study philosophy only when you can spare the time.
If you were sick, you’d stop looking after your personal affairs and forget your business obligations. You wouldn’t think highly enough of any client to take on his case during a brief letup in your illness. You’d do your very best to get rid of the illness as soon as possible. Well, then? Won’t you do the same now? Throw off every obstacle and give your time to getting a healthy mind, because no one can reach it while he’s absorbed in other things.
Philosophy Doesn’t Take Leftovers
Philosophy has her own authority. She sets her own time; she doesn’t let it be set for her. She isn’t something to follow at odd moments, but a practice for every day. She is in charge, and she requires us to show up.
When a certain state promised Alexander part of its territory and half of all its property, he replied: “I invaded Asia not to accept what you might give, but to let you keep whatever I might leave.” Philosophy says the same to every other occupation: “I don’t intend to accept the time you have left over; I’ll let you keep what I leave.”
The Weakness of a Human, the Calm of a God
So turn to her with all your soul, sit at her feet, cherish her. A great distance will then begin to separate you from other people. You’ll be far ahead of all mortals, and even the gods won’t be far ahead of you. Do you ask what the difference will be between you and the gods? They’ll live longer. But truly, it’s the mark of a great artist to fit a complete likeness within the limits of a miniature. The wise person’s life spreads out before him as wide as all eternity does for a god. There’s one point where the wise person has the edge on a god: a god is freed from fear by the gift of nature, the wise person by his own gift.
What a wonderful privilege: to have the weaknesses of a human and the calm of a god! The power of philosophy to blunt the blows of chance is beyond belief. No arrow can lodge in her body; she is well protected and impenetrable. Some arrows she robs of their force and brushes off with the loose folds of her robe, as though they had no power to harm; others she knocks aside and flings back so hard that they return upon the one who shot them.
Farewell.
Breaking It Down: A Modern Take on Letter 53
Letter 53 shows Seneca laughing at himself. The great philosopher, desperate and green, forces a pilot to shore and swims through the surf in his cloak. Then he turns the joke into a diagnosis. Physical illness eventually makes itself known, but faults of character work the opposite way: the deeper they go, the less we see them. His prescription is to put philosophy, the daily work of becoming wiser, first rather than fitting it into the gaps.
1. Laugh at yourself
Seneca blames Ulysses’ troubles on the fact that “he simply got seasick.” A sense of humor about our own weakness keeps philosophy human.
2. We hide our symptoms
We call gout a sprain and fever a chill. Anyone who works in medicine has seen patients explain away warning signs. We do the same with our habits and moods.
3. Hidden faults are the serious ones
Seneca says our failings are “more serious the more hidden they are.” The faults we can’t see are the ones running our lives.
4. The soul’s illness hides itself
“The worse it is, the less you notice it.” If you’re sure you have no serious flaws, that may be the clearest warning sign.
5. Admitting faults is a sign of health
“Only someone who is awake can tell his dream.” Being able to name what’s wrong with us means we’re already waking up.
6. Philosophy wakes us
“Philosophy is the only power that can rouse us.” Reflection, reading, and honest self-examination break the trance of habit.
7. Treat it like your health
If you were sick, you’d drop everything to recover. Seneca asks us to treat the health of our minds with the same urgency.
8. Don’t give wisdom your leftovers
“Don’t study philosophy only when you can spare the time.” What we fit into the cracks of our day rarely changes us. Give it a real place.
9. Make it daily
“She isn’t something to follow at odd moments, but a practice for every day.” Ten focused minutes every morning beats an occasional burst of enthusiasm.
10. Wisdom sets the terms
Like Alexander, philosophy says, “I don’t intend to accept the time you have left over.” Decide what matters first, then let other things fit around it.
11. A short life can be full
“The wise person’s life spreads out before him as wide as all eternity does for a god.” A life well lived is complete at any length, like a fine miniature portrait.
12. Human weakness, divine calm
“To have the weaknesses of a human and the calm of a god!” We’ll still get seasick. But we can meet life’s blows with steady minds.
