"What is our good? Selected thoughts of the Roman philosopher" is a collection of works written by the ancient Greek philosopher Epictetus. It included "Aphorisms" and the treatise "What is our good?" These are the reflections of a well-known, ultimately leading preacher of Stoicism from the classical Greek school about the meaning of life and nature, about morality, happiness and personal freedom. Actually, Epictetus' reflections are the foundations of the philosophical direction of self-improvement and self-development. Epictetus believed that a person should divide all things and circumstances into dependent and independent. In the first case, it is courageous to fulfill one's duty, and to ignore the rest. He was highly valued and referred to by another famous philosopher, the emperor Marcus Aurelius Antoninus in his now cult "Reflections". Epictetus is the nickname of a slave, translated from the Greek language as Purchased. The real name of the philosopher is unknown. Epictetus was a slave of one of the favorites of the Roman emperor Nero. Later released. He left behind no written works, his philosophical speeches were preserved thanks to the records of his student Flavius Arrian. Translated into Ukrainian by Olena Golota.
