Protagoras follows up his mythe by a discourse. Justice and the sense of shame are not professional attributes, but are possessed by all citizens and taught by all to all 269 Constant teaching of virtue. Theory of punishment 270 Why eminent men cannot make their sons eminent 271 Teaching by parents, schoolmaster, harpist, laws, dikastery, &c. _ib._ All learn virtue from the same teaching by all. Whether a learner shall acquire more or less of it, depends upon his own individual aptitude 272 Analogy of learning vernacular Greek. No special teacher thereof. Protagoras teaches virtue somewhat better than others 273 The sons of great artists do not themselves become great artists 274 Remarks upon the mythe and discourse. They explain the manner in which the established sentiment of a community propagates and perpetuates itself 274 Antithesis of Protagoras and Sokrates. Whether virtue is to be assimilated to a special art 275 Procedure of Sokrates in regard to the discourse of Protagoras--he compliments it as an exposition, and analyses some of the fundamental assumptions 276 One purpose of the dialogue. To contrast continuous discourse with short cross-examining question and answer 277 Questions by Sokrates--Whether virtue is one and indivisible, or composed of different parts? Whether the parts are homogeneous or heterogeneous? _ib._ Whether justice is just, and holiness holy? How far justice is like to holiness? Sokrates protests against an answer, "If you please" 278 Intelligence and moderation are identical, because they have the same contrary 279 Insufficient reasons given by Sokrates. He seldom cares to distinguish different meanings of the same term _ib._ Protagoras is puzzled, and becomes irritated 280 Sokrates presses Protagoras farther. His purpose is, to test opinions and not persons. Protagoras answers with angry prolixity _ib._ Remonstrance of Sokrates against long answers as inconsistent with the laws of dialogue. Protagoras persists. Sokrates rises to depart 281 Interference of Kallias to get the debate continued. Promiscuous conversation. Alkibiades declares that Protagoras ought to acknowledge superiority of Sokrates in dialogue 282 Claim of a special _locus standi_ and professorship for Dialectic, apart from Rhetoric _ib._ Sokrates is prevailed upon to continue, and invites Protagoras to question him _ib._ Protagoras extols the importance of knowing the works of the poets, and questions about parts of a song of Simonides. Dissenting opinions about the interpretation of the song 283 Long speech of Sokrates, expounding the purpose of the song, and laying down an ironical theory about the numerous concealed sophists at Krete and Sparta, masters of short speech 283 Character of this speech--its connection with the dialogue, and its general purpose. Sokrates inferior to Protagoras in continuous speech 284
