There are, however, only two modes, to which we can resort, for the definite meaning of words; namely, etymology and authority. Considering the history of our own language, and the nature of its composition, we are enabled satisfactorily to investigate, not only the primitive sense of our terms, but likewise their exact signification, in the languages from whence we imported them: for there still remain, sufficient authentic materials, in our Saxon and Norman records, to verify their original meaning. If we enquire into the causes, which have operated to deflect these terms from their primitive sense, we shall find authority to be the principal source of such corruption; and this infirmity appears to have pervaded most of the languages of those nations which have produced poets, orators, and metaphysicians.[9] When we examine the nature of authority in language, as it now exists, we find it to be the arbitrary employment of words, by particular writers of acknowledged celebrity. Many have become authorities in our language, from having improved its construction; others, by the perspicuous arrangement of subject, by the force of their reasoning, or the light of their philosophy. Although we may allow the highest merit to these eminent writers, a praise, far beyond the dulness and drudgery of verbal criticism; yet it is by no means to be inferred, that they consequently become authorities, for the real and intrinsic meaning of words. It can never be expected, that the great mass of mankind should be etymologists: the generality must be regulated by the "jus et norma loquendi;" but if this jus, be the jus vagum, and the norma capricious, confusion must ensue, and they will scarcely be speaking the same language. Those who are dignified with the title of authorities, ought to agree; for the sound interpreters of the law should never differ. Language is the circulating medium of our thoughts; and the meaning of words much resembles the value of money. But great diversity of opinion prevails. In the minds of some philosophers, money means only metallic currency, which may be assayed, and its real value ascertained; and this seems to relate to etymology. Others less solid in their views, and gifted with a finer fabric of fancy, are disposed to consider the abstractions of paper to be equivalent to the concrete of bullion, and have accordingly constituted it the jus and norma by authority. To insist on the meaning of a word, because its interpretation has been previously assumed, carries no conviction of its truth. The "jus et norma loquendi," must ever prevail as the currency between human beings; but this acknowledgment should not, in the course of circulation, diminish, the undoubted right we possess, to detect and refuse such as are base or counterfeit.
