    According to Diogenes Laertius, Diogenes attached himself to Antisthenes in Athens and took up his ethics of self-sufficiency and toil; modern scholars doubt that they met. Diogenes Laertius VI.21; D. R. Dudley, A History of Cynicism (1937); IEP “Diogenes of Sinope”

    criticised

    Antisthenes rejected Plato’s Forms – he saw a horse but not ‘horseness’ – and mocked Plato in a dialogue called Sathon. Simplicius, In Categorias 208.28–32; Diogenes Laertius 3.35

Position

Antisthenes took from Socrates the conviction that virtue alone suffices for happiness, needing nothing but the strength of a Socrates. Virtue can be taught and, once acquired, cannot be lost; pleasure, wealth and reputation count for little, while toil (ponos) trains the soul – Heracles was his model. He held that education begins with the examination of names, and he attacked Plato’s theory of Forms: in a well-known anecdote, he could see a horse but not “horseness”. Later tradition made him the founder of Cynicism and teacher of Diogenes, which modern scholars doubt. Through the Cynics his ideal of self-sufficiency reached the Stoics.

Life & context

Antisthenes was born in Athens around 445 BCE; his mother is said to have been Thracian. He first studied rhetoric with Gorgias, then became one of the most devoted followers of Socrates and, according to Plato, was present at his death. Afterwards he taught at the Cynosarges gymnasium. Ancient lists record a great many writings, but only two short speeches survive.

Main works

  • Ajax and Odysseus (two short speeches, early 4th century BCE)
  • Sathon (lost polemic against Plato, early 4th century BCE)
