The Megarian school of philosophy, founded by Euclides of Megara, a pupil of Socrates, practised dialectic, and was called the Eristic, or disputatious, sect. The art of disputation appealed to the female sex, and a number of women allied themselves with this school. The first female Dialecticians were the five daughters of Diodorus, an eminent disciple of Euclides, and they conferred much honor on the school. Argia was the most celebrated of the sisters for her mental endowments and dialectic skill, but unfortunately there are but scant records of the philosophical activity of Argia and her four sisters, Artemisia, Menexena, Theognis, and Pantaclea. Hieronymus commends the five for their modesty as well as for their intellectual attainments, and they must have aroused general enthusiasm, as Philo, a disciple of their father, wrote a book about them. Euclides was succeeded by Stilpo as head of the school, and among his hearers was Nicarete of Megara, the daughter of prominent parents, who became renowned for her cleverness and profound learning. She adopted the hetaera life, and was the "companion" of Stilpo himself. The relation was tender and enduring, but she did not restrict herself to one lover. Her favors, however, were not to be won, as usual, by the payment of gold, but through the invention or solution of a difficult sophism. The philosophy of Epicurus was a comfortable and pleasing doctrine for people of light morals, and in consequence we meet with the names of a large number of young and beautiful hetaerae who infested the Gardens of Epicurus, among whom were a Boidion, Hedia, Nicidion, Erotion, Marmarion, and the celebrated Leontium. Their presence gave the enemies of the Epicurean sect justification for characterizing their philosophy as a system of immorality; and the strict moralist and academician Plutarch violently censured the Epicureans "who lived with the hetaera Hedeia or Leontium, spat in the face of virtue, and found the _summum bonum_ in the flesh and in sensuality." While nothing but the names of the other Epicurean hetaeras have survived, Leontium, by her varied accomplishments, has won an abiding prominence in the intellectual world.
