He that is not aware of his ignorance, will be only misled by his knowledge. - Richard Whately

In the present day, however, the province of Rhetoric, in the widest acceptation that would reckoned admissible, comprehends all "Composition in Prose;" in the narrowest sense, it would be limited to "Persuasive Speaking."

Concerning the utility of Rhetoric, it is to be observed that it divides itself into two; first, whether Oratorical skill be, on the whole, a public benefit, or evil; and secondly, whether any artificial system of Rules is conducive to the attainment of that skill.

There is, I conceive, no point in which the idea of dishonest artifice is in most people's minds so intimately associated with that of Rhetoric, as the address to the Feelings or Active Principles of our nature. This is usually stigmatized as "an appeal to the Passions instead of the Reason;" as if Reason alone could ever influence the Will, and operate as a motive, which it no more can, than the eyes, which show a man his road, can enable him to move from place to place; or than a ship provided with a compass, can sail without a wind.
