are palpably erroneous. I attribute this to the carelessness with which men have compiled or made up books of grammar; and that carelessness to those various circumstances, already described, which have left diligence in a grammarian no hope of praise or reward. Without alluding here to my own books, no one being obliged to accuse himself, I doubt whether we have any school grammar that is much less objectionable in this respect, than Murray's; and yet I am greatly mistaken, if nine tenths of all the definitions in Murray's system are not faulty. "It was this sort of definitions, which made Scaliger say, 'Nihil infelicius definitore grammatico.'"--See Johnson's Gram. Com., p. 351; also Paragraph 5th, above.
17. Nor can this objection be neutralized by saying, it is a mere matter of opinion--a mere prejudice originating in rivalry. For, though we have ample choice of terms, and may frequently assign to particular words a meaning and an explanation which are in some degree arbitrary; yet whenever we attempt to define things under the name which custom has positively fixed upon them, we are no longer left to arbitrary explications; but are bound to think and to say that only which shall commend itself to the understanding of others, as being altogether true to nature. When a word is well understood to denote a particular object or class of objects, the definition of it ought to be in strict conformity to what is known of the real being and properties of the thing or things contemplated. A definition of this kind is a proposition susceptible of proof and illustration; and therefore whatsoever is erroneously assumed to be the proper meaning of such a term, may be refuted. But those persons who take every thing upon trust, and choose both to learn and to teach mechanically, often become so slavishly habituated to the peculiar phraseology of their text-books, that, be the absurdity of a particular expression what it may, they can neither discover nor suspect any inaccuracy in it. It is also very natural even for minds more independent and acute, to regard with some reverence whatsoever was gravely impressed upon them in childhood. Hence the necessity that all school-books should proceed from skillful hands. Instruction should tell things as they are, and never falter through negligence.
18. I have admitted that definitions are not the only means by which a general knowledge of the import of language may be acquired; nor are they the only means by which the acquisition of such knowledge may be aided. To exhibit or point out things and tell their names, constitutes a large part of that instruction by which the meaning of words is conveyed to the young mind; and, in many cases, a mere change or apposition of terms may sufficiently explain our idea. But when we would guard against the possibility of misapprehension, and show precisely what is meant by a word, we must fairly define it. There are, however, in every language, many words which do not admit of a formal definition. The import of all definitive and connecting particles must be learned from usage, translation, or derivation; and nature reserves to herself the power of explaining the objects of our simple original perceptions. "All words standing for complex ideas are definable; but those by which we denote simple ideas, are not. For the perceptions of this latter class, having no other entrance into the mind, than by sensation or reflection, can be acquired only by experience."--Duncan's Logic, p. 63. "And thus we see, that as our simple ideas are the materials and foundation of knowledge, so the names of simple ideas may be considered as the elementary parts of language, beyond which we cannot trace the meaning and signification of words. When we come to them, we suppose the ideas for which they stand to be already known; or, if they are not, experience alone must be consulted, and not definitions or explications."--Ibid., p. 69.
19. But this is no apology for the defectiveness of any definition which might be made correct, or for the effectiveness of our English grammars, in the frequent omission of all explanation, and the more frequent adoption of some indirect form of expression. It is often much easier to make some loose observation upon what is meant by a given word or term in science, than to frame a faultless definition of the thing; because it is easier to refer to some of the relations, qualities, offices, or attributes of things, than to discern wherein their essence consists, so as to
