He that hath grasped the administration of the World, who hath learned that this Community, which consists of God and men, is the foremost and mightiest and most comprehensive of all: -- that from God have descended the germs of life, not to my father only and father's father, but to all things that are born and grow upon the earth, and in an especial manner to those endowed with Reason (for those only are by their nature fitted to hold communion with God, being by means of Reason conjoined with Him) --why should not such an one call himself a citizen of the world? Why not a son of God? Why should he fear aught that comes to pass among men? Shall kinship with Caesar, or any other of the great at Rome, be enough to hedge men around with safety and consideration, without a thought of apprehension: while to have God for our Maker, and Father, and Kinsman, shall not this set us free from sorrows and fears?

It is a series of extracts of the teachings of the Stoic philosopher Epictetus written down by Arrian c. 108 AD. It is unlikely to be word-for-word transcriptions and are probably written-up versions of Arrian's lecture notes. The books did not have a formal title in ancient times.

Epictetus (A.D. c. 55 – 135) was a Greek 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.
