Such errors as this, however, are easily corrected, and many of the acute remarks which have been here copied are well worthy the attention of practical grammarians; at the same time enough has been said, without any disparagement of Cobbett’s talents, to show that a man cannot be well qualified to teach that which he has not had the means of properly learning. For although the English language appears at first sight to be extremely simple and philosophical in its structure, it has, in fact, been derived from a variety of heterogeneous sources; it has undergone a variety of vicissitudes, and has served for the expression of a multiplicity of discussions on the most refined subjects in literature and history and science, for [p100] the feelings of oratory, and the passions of poetry, and it has been worn away by degrees, as the crystal in the stream is worn to a pebble, till it has returned to a simplicity which wears the aspect of the immediate offspring of the Chinese or Egyptian or Mexican Hieroglyphics.
