Epictetus

A Greek Stoic philosopher of the Roman era, he was born at Hierapolis in Phrygia around 55 CE and spent part of his early life as a slave before gaining his freedom. He studied philosophy under Musonius Rufus in Rome, an influence that helped shape the practical, disciplined style he became known for.

After being banished from Rome, he settled in Nicopolis in northwestern Greece, where he taught students who came to hear him speak about freedom, duty, and the difference between what we can control and what we cannot. He did not write books himself, as far as we know; his student Arrian preserved his teaching in the Discourses and the short handbook known as the Enchiridion.

What makes his work last is its plain force. He treats philosophy not as abstract theory but as training for everyday life: how to face hardship, govern your reactions, and keep your character steady in an unpredictable world.
