There are few men who do not at times find themselves at a loss, respecting the true pronunciation of certain words. Having no principles or rules, by which they can solve questions of this kind, they imitate some gentleman, whose abilities and character entitle his opinions to respect, but whose pronunciation may be altogether accidental or capricious.

With respect to many words, I have been in the same uncertainty; and used formerly to change my pronunciation, in conformity to the practice of the last man of superior learning whom I heard speak. My enquiries have been directed to investigate some principles, which will remove all difficulties in pronunciation; the result of which is a full satisfaction in my own mind as to almost every particular word. Whether the principles will prove equally satisfactory to others, it is impossible now to determine. Most of the varieties in pronunciation are mentioned in the second and third Dissertations; those which are not, the reader will be enabled to adjust on the principles there unfolded.

It will be observed, that many of the remarks in this publication are not new. This will be no objection to the main design; as some remarks which are found in other philological treatises, are necessary to the general plan of this. A great part however of my opinions are new, and many of them directly opposed to the rules laid down by former writers.

In the singularity of spelling certain words, I am authorized by Sidney, Clarendon, Middleton, Blackstone, Ash, or other eminent writers, whose authority, being supported by good principles and convenience, is deemed superior to that of Johnson, whose pedantry has corrupted the purity of our language, and whose principles would in time destroy all agreement between the spelling and pronunciation of words. I once believed that a reformation of our orthography would be unnecessary and impracticable. This opinion was hasty; being the result of a slight examination of the subject. I now believe with Dr. Franklin that such a reformation is practicable and highly necessary.

It has been my aim to support my opinions by numerous and respectable authorities. In some cases, an author is quoted, but not the chapter or page. This was owing to neglect in first transcribing passages, which was often done, without any design to use the quotations as authorities in the present work; and the passages could not afterwards be found without great trouble, and sometimes the author could not be a second time procured. In a very few instances, a quotation has been taken at second hand on the credit of a faithful writer; but never when I could obtain the original work. Many other ancient authors would have been consulted, had it been practicable; but the most valuable of these are very scarce, and many of them I have not heard of in America. It is to be lamented that old authors are neglected, and modern libraries composed of abridgements, compilations, short essays, &c. which are calculated only for communicating some general information and making superficial scholars, to the prejudice of profound learning and true science.[1]

The American student is often obliged, and too often disposed, to drink at the streams, instead of mounting to the sources of information.

For the remarks on English Verse in the fifth Dissertation, I am much indebted to the celebrated author of M'Fingal, a gentleman who has "drank deep of the Pierian Spring," and who is equally distinguished for wit, erudition, correct taste, and professional knowlege.

In explaining the principles of the language, I have aimed at perspicuity, with a view to render the work useful to all classes of readers. The Notes at the end are designed to illustrate some points by authorities or arguments that could not be properly arranged in the text; and to throw some light on ancient history. To the curious enquirer, these may be as entertaining as the Dissertations themselves. In two or three instances, I have found occasion to change my opinion, since the publication of the Institute; but a future edition of that work will be conformed to the criticisms in these Dissertations.

To those who ask where a writer was born and educated, before they can ascertain the value of his writings, I can only observe, it is expected this publication will fare like all others. Men every where suppose that their own state or country has some excellence that does not belong to their neighbors; and it is well, if they do not arrogate a superiority in every respect. They think their own colleges the best; their professional men the most learned, and their citizens the most liberal and polite. I have been witness to numberless remarks and insinuations of this kind in almost every state in the union; and after personal observation, can affirm that they generally proceed from gross ignorance, or unpardonable prejudice. But it is very natural for men to think and say all these things of home, when they have little or no knowlege of any thing abroad.
