Demonax

Demonax (Greek: Δημώναξ, Dēmōnax, gen.: Δημώνακτος; c. AD 70 – c. 170) was a Greek Cynic philosopher. Born in Cyprus, he moved to Athens, where his wisdom, and his skill in solving disputes, earned him the admiration of the citizens. He taught Lucian, who wrote a Life of Demonax in praise of his teacher. When he died he received a magnificent public funeral.

The only source we have for the life of Demonax is Lucian, who describes Demonax in glowing terms, in contrast to the disreputable Cynics whom Lucian reviled. He is not mentioned by any other contemporary writer. He is mentioned in the 5th century by Eunapius, but only because he knows of him from Lucian's work. It is possible, therefore, that Demonax is a character invented by Lucian. There are, however, some sayings attributed to Demonax found in anthologies compiled by later writers which are not found in Lucian's work.

Demonax was born c. 70 AD, in Cyprus, where he belonged to an influential family. He was led by a love of philosophy to become a philosopher. He was taught by the best philosophers of the day, including Agathobulus, Demetrius, and Epictetus. He eventually moved to Athens, where he seems initially to have offended the citizens, but eventually he came to be regarded with reverence for his resolute character:

To a natural impulse towards the good, an innate yearning for philosophy which manifested itself in childish years, that he owed his superiority to all the things that ordinary men pursue. He took independence and candour for his guiding principles, lived himself an upright, wholesome, irreproachable life, and exhibited to all who saw or heard him the model of his own disposition and philosophic sincerity.

He is described as a peace-maker, able to bring harmony between husband and wife, and to solve disputes between brothers. Lucian compares him to both Socrates and Diogenes, and when Demonax was asked which philosophers he preferred, he is said to have replied, "I admire them all; Socrates I revere, Diogenes I admire, Aristippus I love."
