A Course of Lectures on Oratory and Criticism

While a tutor at Warrington Academy, the polymath Joseph Priestley (1733-1804) established himself as a leading grammarian and educational theorist, producing the influential Rudiments of English Grammar (1761) and A Course of Lectures on the Theory of Language and Universal Grammar (1762), both of which are reissued in this series. In 1762 he also delivered these lectures on rhetorical theory, arguing that the purpose of rhetoric is moral formation. Priestley was deeply influenced by associationism, a theory of mind developed by John Locke and David Hartley. This claims that all complex ideas develop from simple ones, which arise purely from sensory impressions. The orator's role, then, is to form the right associations between impressions and ideas in a listener's mind. Informed by this theory, these thirty-five lectures re-evaluate the classical rhetorical components of topic, method and style. First published in 1777, the work is reissued here in its 1781 Dublin printing.
