6.  I have before said, that to excel in grammar, is but to know better than others wherein grammatical excellence consists; and, as this excellence, whether in the thing itself, or in him that attains to it, is merely comparative, there seems to be no fixed point of perfection beyond which such learning may not be carried.  In speaking or writing to different persons, and on different subjects, it is necessary to vary one’s style with great nicety of address; and in nothing does true genius more conspicuously appear, than in the facility with which it adopts the most appropriate expressions, leaving the critic no fault to expose, no word to amend.  Such facility of course supposes an intimate knowledge of all words in common use, and also of the principles on which they are to be combined.

7.  With a language which we are daily in the practice of hearing, speaking, reading, and writing, we may certainly acquire no inconsiderable acquaintance, without the formal study of its rules.  All the true principles of grammar were presumed to be known to the learned, before they were written for the aid of learners; nor have they acquired any independent authority, by being recorded in a book, and denominated grammar.  The teaching of them, however, has tended in no small degree to settle and establish the construction of the language, to improve the style of our English writers, and to enable us to ascertain with more clearness the true standard of grammatical purity.  He who learns only by rote, may speak the words or phrases which he has thus acquired; and he who has the genius to discern intuitively what is regular and proper, may have further aid from the analogies which he thus discovers; but he who would add to such acquisitions the satisfaction of knowing what is right, must make the principles of language his study.

8.  To produce an able and elegant writer, may require something more than a knowledge of grammar rules; yet it is argument enough in favour of those rules, that without a knowledge of them no elegant and able writer is produced.  Who that considers the infinite number of phrases which words in their various combinations may form, and the utter impossibility that they should ever be recognized individually for the purposes of instruction and criticism, but must see the absolute necessity of dividing words into classes, and of showing, by general rules of formation and construction, the laws to which custom commonly subjects them, or from which she allows them in particular instances to deviate?  Grammar, or the art of writing and speaking, must continue to be learned by some persons; because it is of indispensable use to society.  And the only question is, whether children and youth shall acquire it by a regular process of study and method of instruction, or be left to glean it solely from their own occasional observation of the manner in which other people speak and write.
