Diogenes of Sinope
A distinctive feature of Stoicism is its cosmopolitanism; according to the Stoics, all people are manifestations of the one universal spirit and should live in brotherly love and readily help one another. In the "Discourses", Epictetus comments on man's relationship with the world: "Each human being is primarily a citizen of his own commonwealth; but he is also a member of the great city of gods and men, whereof the city political is only a copy." This sentiment echoes that of Diogenes of Sinope, who said, "I am not an Athenian or a Corinthian, but a citizen of the world."
