His Life, Character, and Philosophy

According to Tacitus, Seneca modelled his death on that of Socrates, discussing philosophy with his friends.

Few philosophers have lived a life as dramatic or conflicted as Seneca’s. The emperor Nero made him the richest man in the Roman Empire before ordering him to commit suicide.

Today, Seneca is our most important primary source on ancient Stoicism, followed by Epictetus, Musonius Rufus, and Marcus Aurelius.

Stoicism has exerted a profound influence on the history of ideas, shaping the thought of Descartes, Spinoza, Leibniz, Schopenhauer, Adam Smith, and J. S. Mill. In mental health, it inspired what has become the world’s most widely practised form of psychotherapy: cognitive behavioural therapy (CBT).

The Teacher’s Pet

Lucius Annaeus Seneca was probably born in 4 BCE, the same year as Jesus, in Corduba (modern-day Córdoba), Hispania.

His father, Seneca the Elder (Lucius Annaeus Seneca Maior), was a Roman equestrian who wrote books on rhetoric and Roman history. His elder brother Novatus, better known as Gallio, became a senator, and his younger brother Mela was the father of the poet Lucan.

Seneca was raised in Rome. His tutors included Attalus the Stoic, Sotion, and Papirius Fabianus. He so admired Attalus that he ‘practically laid siege to his classroom’. He was ‘the first to arrive and the last to leave’ and often left with the desire to be poor.

He suffered from poor health—possibly tuberculosis on a background of asthma—and, from his mid-twenties, spent several years convalescing in Alexandria, where he lived with his mother’s sister and her husband, Gaius Galerius, the governor of Egypt.

The three sailed back to Rome in 32, but Galerius perished in a shipwreck.

These early experiences of illness and uncertainty may help to explain Seneca’s lifelong preoccupation with adversity, mortality, and the best use of life.

Exile on Corsica

A few years after his return, Seneca was elected quaestor, making him a senator.

According to the historian Cassius Dio (d. c. 235 CE), Seneca, ‘who was superior in wisdom to all the Romans of his day and to many others as well,’ spoke so eloquently in the Senate that the emperor Caligula ordered his execution, only to stay the order after being told that he was in any case terminally ill.

In 41, the throne passed to Caligula’s uncle Claudius, and the new empress Messalina, seeking to eliminate a potential rival, accused Caligula’s sister Julia Livilla of adultery with Seneca. The Senate sentenced Seneca to death, but Claudius commuted the sentence to exile on Corsica.

On Corsica, Seneca wrote the Consolation to Polybius, a letter purporting to comfort Polybius, Claudius’ literary secretary, on the death of his brother, but more likely intended to flatter the emperor in the hope of being recalled from exile.

Tutor and Adviser to Nero

In 49, following the downfall of Messalina, Agrippina the Younger, a sister of Caligula and Julia Livilla, married her uncle Claudius, and had Seneca recalled to tutor her twelve-year-old son, Nero.

When the lad acceded to the throne in 54, Seneca became his adviser and, alongside the praetorian prefect Sextus Afranius Burrus, provided good government during the first five, relatively benign, years of his reign, the so-called quinquennium Neronis.

In 58, the senator Publius Suilius Rufus, who had been close to Claudius, began attacking Seneca with a series of accusations centred upon his rapid rise to fabulous wealth. ‘By what kind of wisdom or maxims of philosophy,’ he inveighed, ‘has Seneca within four years of royal favour amassed three hundred million sesterces?’ In response, Seneca prosecuted Suilius, who was banished to the Balearic Islands.

The charge has echoed down the centuries. How could a Stoic philosopher preach simplicity while becoming the richest man in Rome?

In 59, Nero had Agrippina murdered, and Seneca wrote the self-exculpatory speech that he delivered to the Senate, a speech so artful that the senators moved to congratulate the emperor upon his own mother’s murder.

Downfall and Suicide

But now the tide would turn against our man.

After the death of Burrus in 62, Seneca lost whatever remained of his restraining influence over Nero. Having read the runes, he twice petitioned to retire, once in 62 and again in 64, but Nero refused to cut him loose. Still, he contrived to spend almost all his time on his country estates, working, among others, on his Letters to Lucilius.

His prolonged absences from court may have stoked Nero’s suspicions. When, in 65, the Pisonian conspiracy to overthrow Nero came to light, the emperor condemned a first wave of nineteen people to death, among them Seneca and his nephew Lucan.

By the end of the year, Seneca, his two brothers, and the twenty-five-year-old Lucan had all four been made to commit suicide.

According to the historian Tacitus (d. 120 CE), Seneca modelled his death on that of Socrates, discussing philosophy with his friends and chiding them for their outbursts of emotion.

He slit one vein, and then another, and then a few more, but would not bleed enough to die. Now in considerable pain, he took some hemlock, but this too failed to do the deed. At last, to dilate his veins and ease the pain, he immersed himself in a hot bath and finally suffocated to death.

His wife Pompeia Paulina, whom he had married in later life, attempted to share his fate, but Nero ordered that she be rescued and bandaged up.

Legacy

Seneca had seen the writing on the wall, which is why he worked so assiduously in his final years, seeking, through the Letters, to make himself as immortal as any mortal can be.

Even his carefully staged suicide may have been a part of that immortality project. Tacitus hints as much when, having related Seneca’s last words to his friends, he writes, ‘After these and some similar remarks, which might have been meant for a wider audience…’

Upon his death, Seneca’s works were instantly popular and, according to Quintilian, were ‘in the hands of every young man’. Seneca has been read by most everyone since, including the ‘French Seneca’, Michel de Montaigne, who modelled his Essays upon the Letters.
