Epictetus, a celebrated Stoic philosopher of the 1st century, originally a slave; lived and taught at Rome, but after the expulsion of the philosophers retired to Nicopolis, in Epirus; was lame, and lived in poverty; his conversations were collected by Arrian, and his philosophy in a short manual under the Greek name of "Enchiridion of Epictetus," written, as is alleged, in utter obliviousness of the fact that "the end of man is an action, not a thought."
