"Hermarchus or Hermarch (Greek: \u1F1D\u03C1\u03BC\u03B1\u03C1\u03C7o\u03C2, Hermarkhos, \"reign of Hermes\"; c. 325-c. 250 BCE), sometimes incorrectly written Hermachus (Greek: \u1F1D\u03C1\u03BC\u03B1\u03C7o\u03C2, Hermakhos), was an Epicurean philosopher. He was the disciple and successor of Epicurus as head of the school. None of his writings survive. He wrote works directed against Plato, Aristotle, and Empedocles. A fragment from his Against Empedocles, preserved by Porphyry, discusses the need for law in society."@en . . .
