Seneca's Letters to Lucilius are the friendliest way into Stoicism. Here is how to approach them and five letters worth reading first.
Late in his life Seneca wrote 124 letters to his friend Lucilius. They read less like a textbook and more like advice from a wise, slightly sardonic older friend. If you want to start reading Stoicism in the original (in translation), they are a good place to begin.
How do you read them?
- Do not read them straight through. Dip in, one letter at a time. Most are only a few pages.
- Pick a readable translation. Older versions such as Richard Mott Gummere's Loeb translation are free online; modern ones are smoother.
- Note one line per letter. Seneca usually closes with a quotation or maxim for Lucilius to think about.
Five letters to start with
- Letter 1, "On saving time". The famous opening: hold every hour in your grasp.
- Letter 2, "On discursiveness in reading". Read a few good authors deeply rather than skimming many.
- Letter 7, "On crowds". Why the company you keep shapes your character.
- Letter 13, "On groundless fears". We suffer more in imagination than in reality.
- Letter 18, "On festivals and fasting". Practise living simply now and then so that hardship holds less fear.
A note on Seneca himself
Seneca was very wealthy and served Nero, and critics in his own time called him a hypocrite. He was aware of the charge and addressed it. Reading him with that tension in mind makes the letters more interesting, not less.
Five more letters worth reading
- Letter 28, "On travel as a cure for discontent": running away doesn't help if you take your troubles with you.
- Letter 47, "On master and slave": a striking argument, for its time, that enslaved people share the same humanity and deserve decent treatment.
- Letter 56, "On quiet and study": Seneca, living above a noisy bathhouse, argues real calm comes from within.
- Letter 63, "On grief for lost friends": gentle advice on mourning without being consumed by it.
- Letter 104, "On care of health and peace of mind": on fleeing your problems versus facing them.
Letter numbers and titles vary slightly between translations, but the Gummere titles above are the most widely used online.
Themes to look out for
- Time: Seneca returns again and again to how we waste it.
- Friendship: real friends improve each other, and choosing them carefully matters.
- Death: thinking about mortality, he argues, frees us to live fully rather than fearfully.
- Wealth: not wrong in itself, but dangerous if you depend on it.
- Daily practice: philosophy is training, not just reading.
Seneca borrows from Epicurus
A surprise for many readers: in the early letters, Seneca often closes with a saying from Epicurus, founder of a rival school. He explains that he'll take good ideas from anywhere. It's a useful reminder that Stoicism isn't a closed system.
A simple reading plan
- Read one letter a day or a few a week.
- Copy one sentence into a notebook.
- Write a line about where it applies in your own life this week.
- Every month, reread your notes and pick the idea that stuck.
- Don't worry about finishing: even a dozen letters, read slowly and applied, will teach you more than racing through all 124.
