existence;--of that learning which lifts the soul from earth, and
enables it to hold converse with a thousand worlds. In pursuing any and
every other path of science, you will discover the truth of these
remarks, and feel its force; for you will find, that, as grammar opens
the door to every department of learning, a knowledge of it is
indispensable: and should you not aspire at distinction in the republic
of letters, this knowledge cannot fail of being serviceable to you, even
if you are destined to pass through the humblest walks of life. I think
it is clear, that, in one point of view, grammatical knowledge possesses
a decisive advantage over every other branch of learning. Penmanship,
arithmetic, geography, astronomy, botany, chemistry, and so on, are
highly useful in their respective places; but not one of them is so
universally applicable to practical purposes, as this. In every
situation, under all circumstances, on all occasions;--when you speak,
read, write, or think, a knowledge of grammar is of essential utility.

Doubtless you have heard some persons assert, that they could detect and
correct any error in language by the ear, and speak and write accurately
without a knowledge of grammar. Now your own observation will soon
convince you, that this assertion is incorrect. A man of refined taste,
may, by perusing good authors, and conversing with the learned, acquire
that knowledge of language which will enable him to avoid those glaring
errors that offend the ear; but there are other errors equally gross,
which have not a harsh sound, and, consequently, which cannot be
detected without a knowledge of the rules that are violated. Believe me,
therefore, when I say, that without the knowledge and application of
grammar rules, it is impossible for any one to think, speak, read, or
write with accuracy. From a want of such knowledge, many often express
their ideas in a manner so improper and obscure as to render it
impossible for any one to _understand_ them: their language frequently
