The School
Voices
The Stoics themselves, from Zeno's portico to today's interpreters. Each entry has dates, key concepts, and where to start reading.
Early Stoa
Chrysippus of Soli
c. 279 – 207 BCEThird head of the Stoa and its systematic architect. Wrote 705 books. None survive. Without him, no Stoa.
Cleanthes of Assos
c. 330 – 230 BCEThe second head of the Stoa. A former water-carrier and boxer, devout, slow, and uncompromising; author of the Hymn to Zeus that gave the school its theological centre.
Zeno of Citium
c. 334 – 262 BCEFounder of the Stoa. A Phoenician merchant shipwrecked in Athens who lost his cargo and found a philosophy.
Middle Stoa
Panaetius of Rhodes
c. 185 – 109 BCEThe Stoic who brought the philosophy to Rome. Softened the system to fit the practical life of the Roman aristocrat — and so made it possible for Cicero, Seneca, and Marcus to follow.
Posidonius of Apamea
c. 135 – 51 BCEStoic polymath — philosopher, geographer, astronomer, historian. The last great systematic Stoic before the Roman imperial period, and probably the most learned man of his age.
Roman Stoa
Epictetus
c. 50 – 135 CEThe freed slave whose elenctic interrogations of his students became the Discourses — the Stoic teacher modern practice most directly inherits.
Gaius Musonius Rufus
c. 25 – c. 100 CERoman knight, Stoic teacher, twice exiled — the man whose lectures shaped Epictetus and whose practical austerity defined what Roman Stoicism looked like in practice.
Hierocles the Stoic
2nd century CESecond-century Stoic ethicist whose surviving fragments give us the clearest ancient statement of the doctrine of oikeiosis and the famous concentric circles of concern.
Lucius Annaeus Seneca
c. 4 BCE – 65 CEStatesman, dramatist, and the Stoic whose voice — warm, literary, conversational — has carried the philosophy farthest into modern reading.
Marcus Aurelius
121 – 180 CERoman emperor and reluctant philosopher. His Meditations are the most sustained private record of Stoic practice ever written.
Modern Conduits
Donald Robertson
b. 1972Cognitive-behavioural therapist who has done more than any other modern figure to map Stoicism onto clinical CBT — and back again, returning practical bite to a tradition that had drifted toward inspirational quotation.
John Sellars
b. 1971British philosopher and historian of philosophy whose work on Hellenistic ethics has become a standard scholarly reference for contemporary Stoic study, and whose short trade books are the cleanest non-self-help introductions to the school.
Lawrence C. Becker
1939 – 2018American moral philosopher whose A New Stoicism (1998, expanded 2017) is the most serious modern attempt to reconstruct Stoic ethics for a naturalistic, post-providential reader — the academic book the contemporary revival has built on without always naming.
Massimo Pigliucci
b. 1964Philosopher of science and contemporary Stoic teacher. Wrote the most accessible modern systematic introduction to living Stoicism — including its harder doctrinal commitments, not just its motivational surface.
Pierre Hadot
1922 – 2010French historian of philosophy. Recovered ancient philosophy — Stoic, Epicurean, and Platonic — as a way of life and a set of spiritual exercises, not a set of doctrinal propositions.
Ryan Holiday
b. 1987American author and media operator whose books and daily emails carried modern Stoicism to a wider audience than any other figure has reached.
William B. Irvine
b. 1952American philosopher whose Guide to the Good Life (2009) was the book that broke modern Stoicism into general readership. Most useful for daily negative visualisation and the trichotomy of control.
