of learning are no less injured by whimsical doctrines, than the rights of authorship by plagiarism. Too many of our grammars, profitable only to their makers and venders, are like weights attached to the heels of Hermes. It is discouraging to know the history of this science. But the multiplicity of treatises already in use, is a reason, not for silence, but for offering more. For, as Lord Bacon observes, the number of ill-written books is not to be diminished by ceasing to write, but by writing others which, like Aaron's serpent, shall swallow up the spurious.[5]
19. I have said that some grammars have too much originality, and others too little. It may be added, that not a few are chargeable with both these faults at once. They are original, or at least anonymous, where there should have been given other authority than that of the compiler's name; and they are copies, or, at best, poor imitations, where the author should have shown himself capable of writing in a good style of his own. What then is the middle ground for the true grammarian? What is the kind, and what the degree, of originality, which are to be commended in works of this sort? In the first place, a grammarian must be a writer, an author, a man who observes and thinks for himself; and not a mere compiler, abridger, modifier, copyist, or plagiarist. Grammar is not the only subject upon which we allow no man to innovate in doctrine; why, then, should it be the only one upon which a man may make it a merit, to work up silently into a book of his own, the best materials found among the instructions of his predecessors and rivals? Some definitions and rules, which in the lapse of time and by frequency of use have become a sort of public property, the grammarian may perhaps be allowed to use at his pleasure; yet even upon these a man of any genius will be apt to set some impress peculiar to himself. But the doctrines of his work ought, in general, to be expressed in his own language, and illustrated by that of others. With respect to quotation,
