Epictetus (/ˌɛpɪkˈtiːtəs/; Greek: Ἐπίκτητος; c. AD 55 – 135) was a Greek speaking Stoic philosopher. He was born a slave at Hierapolis, Phrygia (present day Pamukkale, Turkey), and lived in Rome until his banishment, when he went to Nicopolis in north-western Greece for the rest of his life. His teachings were written down and published by his pupil Arrian in his Discourses.
Epictetus taught that philosophy is a way of life and not just a theoretical discipline. To Epictetus, all external events are determined by fate, and are thus beyond our control; 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.
