Who can tell how much of his own good or ill success, how much of the favour or disregard with which he himself has been treated, may have depended upon that skill or deficiency in grammar, of which, as often as he has either spoken or written, he must have afforded a certain and constant evidence.[53] 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.

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.
