A Discourse Being Introductory to his Course of Lectures on Elocution and the English Language (1759)

The lecture introduces a program of instruction in elocution and argues that spoken delivery, not written characters alone, carries the true persuasive and aesthetic power of language. It sets out principles for cultivating tone, gesture, and expression, links those practices to classical rhetorical models, and proposes that improved public speaking will benefit religion, morals, education, and public life. The discourse combines practical guidance on voice and manner with a broader argument that methodical training in oral expression can refine taste, strengthen civic discourse, and restore neglected aspects of national and individual culture.
