Thomas Sheridan, A Discourse Being Introductory to his Course of Lectures on Elocution and the English Language…
“ Can any man communicate more knowlege than he is himself possessed of? Can any man teach an art which he never learned? Can any man instruct others in a language, in which he never was instructed? Can either any art or language be regularly taught without a well digested system of rules? And if no such system has hitherto been formed, either with respect to the English language, or the art of speaking it, how shall any man set about teaching them? ”
