Lucius Annaeus Seneca was born around 4 BCE in Córdoba, Spain, and died in 65 CE in Rome. He died by his own hand, on the order of Emperor Nero, whom he had tutored and advised for eight years. Seneca's life is the most tangled of the three great Stoics. He was hugely wealthy and held enormous political power, yet he wrote with cutting skill about the dangers of wealth, power, and getting tangled in politics. Critics then and now have called him a hypocrite: a Stoic philosopher who built one of the largest private fortunes in Roman history. His defenders say he was playing a long game, using his position to hold back Nero's worst impulses in the early years, while knowing the relationship would eventually kill him. Both readings are probably part true. Seneca was a genuinely wise man living inside real compromise. That may make him the most relatable of the three Stoics to anyone who has ever had to work inside a corrupt system.
The Letters from a Stoic, in Latin the Epistulae Morales ad Lucilius, are 124 letters Seneca wrote to his friend Lucilius in the last years of his life. They are the most personal and the most beautifully written of all Stoic texts. Seneca writes with urgency, wit, and warmth, and sometimes with something close to desperation, like a man who knows time is running out and wants to pass on everything he has learned before it is too late. The letters range from reflections on friendship, death, time, and virtue to plain advice on travel, crowds, handling anger, and coping with illness. They are the easiest way into Stoic philosophy because they read like letters from a wise, honest friend, someone who has made mistakes and is not hiding it.
Seneca's most famous essay is 'On the Shortness of Life,' in Latin De Brevitate Vitae, and its main point is one of the sharpest in all of philosophy. Life is not short, Seneca says. We get plenty of time. The trouble is that we waste most of it on things that are not really ours: ambition, entertainment, distraction, other people's agendas, and the habit of putting off real living until some future moment of readiness that never comes. 'Omnia, Lucili, aliena sunt, tempus tantum nostrum est,' he writes: 'Everything is alien to us, Lucilius; time alone is ours.' And then most people give even that away. The Stoic view of time is not about productivity in the modern hustle sense. It is about turning your attention back toward what truly matters. And that starts with accepting that death is certain and you have less time than you think.
When Seneca's death finally came, he met it as a Stoic to the last. Nero's messengers ordered him to take his own life. Seneca gathered his closest friends, dictated his final thoughts, and opened his veins. When the bleeding was too slow, he drank hemlock. When that too was slow, he was carried to a steam bath, where he finally suffocated. His wife Paulina tried to die with him, but Nero ordered her wounds bound. People watched it happen. Tacitus described it in the Annals and compared it directly to the death of Socrates in the Phaedo. Seneca had spent decades writing about how to die well. When the time came, by every account, he did.
