No one complains of the rules of Grammar as fettering Language; because it is understood that correct use is not founded on Grammar, but Grammar on correct use. A just system of Logic or of Rhetoric is analogous, in this respect, to Grammar.
Richard Whately in: Elements of Rhetoric (1828), p. 17 and in: Encyclopædia metropolitana; or, System of universal knowledge, Encyclopaedia, 1849
