Three ancient lives with almost nothing in common, put in one room — and ten lessons on why anyone believes a text at all.

Inside this path
Stoicism has three surviving voices, and their lives have almost nothing in common. Epictetus was born a slave and taught in exile. Marcus Aurelius ran the Roman empire. Seneca wrote about the contempt of wealth while amassing a fortune large enough to become a public scandal, tutored the emperor who later ordered him to open his veins, and left the most polished prose of the three. This path tests one doctrine against three impossible lives, and then tests the three texts themselves — a notebook nobody was meant to read, letters written for publication under the cover of friendship, and lecture notes taken by a student. You finish able to say why you believe a text, and what a writer's life can and cannot prove about their argument.

Why the three canonical Stoics are usually read as one voice, and what happens when you put their actual lives side by side.
How *Meditations* reached us, why the strongest thing about it is also the least verifiable thing about it, and what "private" can actually be shown to mean.
Marcus Aurelius had every external good the doctrine calls indifferent — and the question of whether that makes his testimony worth more or worth less.
The case against Seneca, stated at full strength: the fortune, the years at Nero's court, and the letter he wrote after the emperor murdered his own mother.
Seneca's *Moral Letters* as a document — who Lucilius was, why the intimacy is both genuine and a technique, and how Seneca answered the charge in writing.
How Seneca died, why the scene is composed like a piece of literature, and whether a good death can settle an account run up over a life.
Epictetus — how a slave came to be given a philosophical education, what the ancient sources actually say about his lameness, and whether having nothing makes his testimony stronger or just differently convenient.
The *Discourses* as a document — Arrian's preface, the argument from the Greek, and the reason the disclaimer is weaker evidence than it sounds.
Slavery, and what all three Stoics said about it — the most humane page any Roman wrote on the subject, and the exact point at which it stops.
Ranking the three documents by how much they can be believed, filling in the three columns for all three men, and the general instrument for weighing anyone who tells you how to live.
