If the discourse which is now about to be read1 had been like the speeches which are produced either for the law-courts2 or for oratorical display,3 I should not, I suppose, have prefaced it by any explanation. Since, however, it is novel and different in character, it is necessary to begin by setting forth the reasons why I chose to write a discourse so unlike any other; for if I neglected to make this clear, my speech would, no doubt, impress many as curious and strange.
