A short history of Stoicism: how it started in Athens, the key figures in Greece and Rome, and why it still matters.
Stoicism ran for roughly five centuries and was shaped by dozens of thinkers. Most of their writing is lost. Here is a quick guide to the names you will meet most often.
The Greek founders
Zeno of Citium (c. 334–262 BC) taught in Athens at the Stoa Poikile, the "painted porch", which gave the school its name. Cleanthes succeeded him and wrote the Hymn to Zeus, one of the few early Stoic texts to survive in full. Chrysippus (c. 279–206 BC) systematised Stoic logic and ethics, and later writers treated him as the school's greatest authority.
The Roman Stoics
The Stoic writing most people read today comes from the Roman period.
- Seneca (c. 4 BC–AD 65) was a statesman, playwright and adviser to Nero. His Letters to Lucilius are warm, practical and still very readable.
- Musonius Rufus taught in Rome in the first century AD and argued, unusually for his time, that women should study philosophy.
- Epictetus (c. AD 50–135) was born into slavery and later taught in Nicopolis. His student Arrian recorded his teaching in the Discourses and the short Enchiridion.
- Marcus Aurelius (AD 121–180) was Roman emperor. His private notebook, now called the Meditations, was never meant for publication.
Why it lasted?
Stoicism offered a way to live well whatever your circumstances, which is why it appealed to a former slave and an emperor alike. That same practicality explains its modern revival, including its influence on cognitive behavioural therapy.
Lesser-known names worth knowing
- Panaetius (c. 185–109 BC) helped bring Stoicism to Rome, making it more practical and less severe, and influenced Cicero.
- Posidonius (c. 135–51 BC) was a polymath who wrote on history, geography and astronomy as well as philosophy. Cicero studied with him in Rhodes.
- Cato the Younger (95–46 BC) was a Roman senator famous for his stubborn integrity and opposition to Julius Caesar. Later Stoics held him up as an example of virtue in practice.
- Hierocles (2nd century AD) described our obligations as circles widening from ourselves to family, community and all humanity, urging us to draw the outer circles inward.
The three parts of Stoic philosophy
The Stoics divided philosophy into three linked parts, sometimes compared to an orchard: logic as the protective wall, physics as the trees, and ethics as the fruit.
- Logic: how to reason clearly and judge impressions correctly.
- Physics: the nature of the universe, which they saw as rational and ordered.
- Ethics: how to live well, the part most modern readers focus on.
How Stoicism faded, and returned?
After Marcus Aurelius, Stoicism declined as a distinct school, but its ideas were absorbed into early Christian thought and later philosophy. Renaissance thinkers such as Justus Lipsius revived interest, and writers from Montaigne to Adam Smith drew on Stoic ideas.
In the 20th century, the psychologists Albert Ellis and Aaron Beck cited Epictetus's idea that our judgements shape our emotions as an influence on their therapies. Today's revival includes popular books, podcasts and the academic-led Modern Stoicism project.
Where to read them?
- Older translations of Marcus Aurelius, Seneca and Epictetus are free on Project Gutenberg and Wikisource.
- Fragments of the early Greek Stoics survive mainly in later writers, such as Diogenes Laertius's Lives of the Eminent Philosophers.
- The Stanford Encyclopedia of Philosophy has free scholarly entries on each major figure.
- For a first read, start with the Romans: they're the most complete, the most practical and the easiest to enjoy.
