Gibbon has furnished a new idea in the art of reading! We ought, says he, not to attend to the _order of our books, so much as of our thoughts_. "The perusal of a particular work gives birth perhaps to ideas unconnected with the subject it treats; I pursue these ideas, and quit my proposed plan of reading." Thus in the midst of Homer he read Longinus; a chapter of Longinus led to an epistle of Pliny; and having finished Longinus, he followed the train of his ideas of the sublime and beautiful in the Inquiry of Burke, and concluded with comparing the ancient with the modern Longinus. Of all our popular writers the most experienced reader was Gibbon, and he offers an important advice to an author engaged on a particular subject: "I suspended my perusal of any new book on the subject till I had reviewed all that I knew, or believed, or had thought on it, that I might be qualified to discern how much the authors added to my original stock." These are valuable hints to students, and such have been practised by others.[24] Ancillon was a very ingenious student; he seldom read a book throughout without reading in his progress many others; his library-table was always covered with a number of books for the most part open: this variety of authors bred no confusion; they all assisted to throw light on the same topic; he was not disgusted by frequently seeing the same thing in different writers; their opinions were so many new strokes, which completed the ideas which he had conceived. The celebrated Father Paul studied in the same manner. He never passed over an interesting subject till he had confronted a variety of authors. In historical researches he never would advance, till he had fixed, once for all, the places, time, and opinions--a mode of study which appears very dilatory, but in the end will make a great saving of time, and labour of mind: those who have not pursued this method are all their lives at a loss to settle their opinions and their belief, from the want of having once brought them to such a test. I shall now offer a plan of Historical Study, and a calculation of the necessary time it will occupy, without specifying the authors; as I only propose to animate a young student, who feels he has not to number the days of a patriarch, that he should not be alarmed at the vast labyrinth historical researches present to his eye. If we look into public libraries, more than thirty thousand volumes of history may be found.
