Dialectic Vs Rhetoric

One more prominent figure in the classical history of rhetoric is Plato (428-347 B.C). Plato believed that the purpose of philosophy was to discover truth that should be independent of any special calculation of interest; he was suspicious of rhetoric because he thought it lacked any concern with a truth that was separate from the speaker’s interest. An opposition therefore developed in the classical period between rhetoric and dialectic (1), dialectic gave equal weight to both sides of an argument, while rhetoric was concerned with persuasion from a particular perspective rather than presenting a balanced point of view. For Plato, rhetoric was deceptive, because it only showed a perspective that fitted with the speaker’s point of view.
