I am sensible that this introduction, as being derived not from the principles of Eloquence, but from the deepest recesses of Philosophy, will excite the censure, or at least the wonder of many, who will think it both unfashionable and intricate. For they will either be at a loss to discover it's connection with my subject, (though they will soon be convinced by what follows, that, if it appears to be far-fetched, it is not so without reason;)--or they will blame me, perhaps, for deserting the beaten track, and striking out into a new one. But I am satisfied that I often appear to advance novelties, when I offer sentiments which are, indeed, of a much earlier date, but happen to be generally unknown: and I frankly acknowledge that I came forth an Orator, (if indeed I am one, or whatever else I may be deemed) not from the school of the Rhetoricians, but from the spacious walks of the Academy. For these are the theatres of diversified and extensive arguments which were first impressed with the foot-steps of Plato; and his Dissertations, with those of other Philosophers, will be found of the greatest utility to an Orator, both for his exercise and improvement; because all the fertility, and, as it were, the materials of Eloquence, are to be derived from thence;--but not, however, sufficiently prepared for the business of the Forum, which, as themselves have frequently boasted, they abandoned to the _rustic Muses_ of the vulgar! Thus the Eloquence of the Forum, despised and rejected by the Philosophers, was bereaved of her greatest advantages:--but, nevertheless, being arrayed in all the brilliance of language and sentiment, she made a figure among the populace, nor feared the censure of the judicious few. By this means, the learned became destitute of a popular Eloquence, and the Orators of polite learning.
