The relation of Isocrates and Aristotle has mostly been defined by scholars as a competition or rivalry between them in a debate over the ends of rhetorical education. This essay investigates Isocrates-quotations in the Rhetoric of Aristotle and calls for a re-evaluation of the relation of Aristotle to Isocrates and to Demosthenes. Aristotle studied thoroughly the Isocratic speeches (especially Helena, Evagoras, Panegyricus, De pace, Antidosis, Philippus) and Isocrates is the only of the canon of ten Attic orators, who is quoted (...) regularly in the Rhetoric. For textual criticism the quotations of Aristotle should be used with caution, as Aristotle often quoted from memory, but his readings must not be excluded a priori. Aristotle recognizes the leading role of Isocrates as a master of literary prose in the development of rhetoric, particularly the epideictic speech. In Aristotle and the earlier Peripatetics Isocrates, who exerts influence on the ethos of the reader, has a prominent position, unlike Demosthenes, who is characterized by his ability to arouse emotions. In this judgement political reasons (promacedonian - antimacedonian) are also visible. (shrink)
