 A Greek philosopher of 1st and early 2nd centuries C.E., and an exponent of Stoic ethics notable for the consistency and power of his ethical thought and for effective methods of teaching. Epictetus’s chief concerns are with integrity, self-management, and personal freedom, which he advocates by demanding of his students a thorough examination of two central ideas, the capacity he terms ‘volition’ (prohairesis) and the correct use of impressions (chrēsis tōn phantasiōn), Heartfelt and satirical by turns, Epictetus has had significant influence on the popular moralistic tradition, but he is more than a moralizer; his lucid resystematization and challenging application of Stoic ethics qualify him as an important philosopher in his own right.
