Cleinomachus
Κλεινόμαχος
(Κλεινόμαχος), a Megaric philosopher of Thurium, is said by Diogenes Laertius (2.112) to have been the first who composed treatises on the fundamental principles of dialectics (περὶ ἀξιωμάτων καὶ κατηγορημάτων). We learn from Suidas (s. v. Πύρρων), that Pyrrhon, who flourished about 330 B. C., attended the instructions of Bryso, and that the latter was a disciple of Cleinomachus. We may therefore set the date of Cleinomachus towards the commencement of the same century.
