Epictetus

Epictetus was a Greek Stoic philosopher. He was born into slavery at Hierapolis, Phrygia and lived in Rome until his banishment, when he went to Nicopolis in northwestern Greece, where he spent the rest of his life.
Epictetus studied Stoic philosophy under Musonius Rufus, and after his manumission began to teach philosophy. After his banishment to Nicopolis, he founded a school there. Epictetus taught that philosophy is a way of life and not simply a theoretical discipline. To Epictetus, all external events are beyond our control; he argues that we should accept whatever happens calmly and dispassionately. However, individuals are responsible for their own actions, which they can examine and control through rigorous self-discipline. His teachings were written down and published by his pupil Arrian in his Discourses and Enchiridion.
