Overview
Seneca's correspondence with his friend Lucilius provides practical Stoic wisdom on living well, facing adversity, and preparing for death.
Seneca the Younger, a Roman Stoic philosopher and advisor to Nero, wrote his moral letters to his friend Lucilius in the last years of his life, between roughly 63 and 65 CE. Ordered to commit suicide by Nero in 65 CE, he wrote much of this work under the shadow of political danger. The 124 letters that survive are among the best pieces of practical philosophy ever written.
Key Ideas
Time is our most precious resource
Most people squander their lives on trivial pursuits.
Adversity is training
Difficulty strengthens character just as fire tests gold.
Live according to nature
Align your desires with reason rather than chasing external pleasures.
Who should read this
Readers who want Stoic philosophy delivered in the form of letters from a friend — specific, warm, and addressed to a particular person rather than to posterity. Seneca is the most immediately applicable of the major Stoics, because his examples are drawn from the ordinary social, financial, and emotional life of a Roman gentleman.
Who might skip it
Skip if Seneca's biography troubles you — he was enormously wealthy and complicit in Nero's regime, and some critics find his moral advice hard to take from a man living as he lived. The question of whether philosophy survives the life of its author is one each reader has to answer.
The verdict
The most re-readable of the Stoic texts alongside Marcus Aurelius's Meditations. Seneca writes shorter, lighter, and more directly than Epictetus, and the letter form gives each piece a clear occasion. The Robin Campbell selection for Penguin is the edition I own; it omits about a third of the letters but captures the essential Seneca.
"We suffer more often in imagination than in reality."
