Whatever is Rational is Tolerable

Epictetus (c.ad 55–135) was a teacher and Graeco-Roman philosopher. Originally a slave from Hierapolis in Anatolia (modern Turkey), he was owned for a time by a prominent freedman at the court of the emperor Nero. After gaining his freedom he moved to Nicopolis on the Adriatic coast of Greece and opened a school of philosophy there. His informal lectures (the Discourses) were transcribed and published by his student Arrian, who also composed a digest of Epictetus’ teaching known as the Manual (or Enchiridion). Late in life Epictetus retired fromteaching, adopted an orphan child and lived out his remaining years in domestic obscurity. His thought owes most to Stoicism, but also reflects the influence of other philosophers, Plato and Socrates in particular. His influence has been deep and enduring, from Marcus Aurelius in his Meditations to the contemporary psychologist Albert Ellis, who has acknowledged his debt to Epictetus in devising the school of Rational-Emotive Behavioural Therapy.
