Epictetus was a Greek Stoic philosopher. He was probably born a slave at Hierapolis, Phrygia (present day Pamukkale, Turkey), and lived in Rome until his exile to Nicopolis in northwestern Greece, where he lived most of his life and died. His teachings were noted down and published by his pupil Arrian in his Discourses. Philosophy, he taught, 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, but we can accept whatever happens calmly and dispassionately. Individuals, however, are responsible for their own actions which they can examine and control through rigorous self-discipline. Suffering arises from trying to control what is uncontrollable, or from neglecting what is within our power. As part of the universal city that is the universe, human beings have a duty of care to all fellow humans. The person who followed these precepts would achieve happiness.
As with most of the major Stoic writings, "How to Live" by Epictetus is littered throughout with arcane nuggets of wisdom. For the modern reader, however, the text is verbose and circumlocutory. Additionally, a lot of the narrative, like regularly instructing the reader on how to treat their slaves, is sorely out of time. Even so, the cardinal virtues of stoicism (wisdom, courage, justice, and temperance) are concepts worth celebrating and using in the construction of a good life. Modern times can just do without the superfluous ideological nonsense of antiquity.
