Coeval with that sovereign, was[was] Johannes de Sacro-Bosco,[[51]] a famous English ecclesiastic, who was the first astronomical writer that acquired celebrity in the thirteenth century. Very nearly about the same time, appeared also that prodigy of genius and learning, Friar Bacon:[[52]] and from that period, down to our own day, there has been a succession of illustrious philosophers: whose names have justly been renowned, for the benefits they have conferred on mankind; names which reflect honour on the countries to which they respectively belong. Many of those benefactors of the world were honoured with marks of high distinction, by their sovereigns and cotemporaries; and their fame will descend to the latest posterity.

In recording these Memoirs of the Life of an American Philosopher, whose name adds dignity to the country that gave him birth, it is the design of the author to represent him as he truly was; and in doing so, he feels a conscious satisfaction, that his pen is employed in delineating the character of a man, who was rendered singularly eminent by his genius, his virtues and his public services. Deeply impressed with the magnitude and importance, as well as delicacy of the subject, the writer has not undertaken the task without some hesitation. He is sensible of the difficulties attending it, and conscious of his inability to do justice to its merits. Arduous, however, as the undertaking is, and since no abler pen has hitherto attempted any thing more, on this subject, than to eulogize[[53]] some of the prominent virtues and talents of our philosopher, his present biographer will endeavour, by the fidelity with which he shall portray the character of that truly estimable man, to atone for the imperfections of the work in other respects. Possessing, as he does, some peculiar advantages, in relation to the materials necessary for this undertaking, he flatters himself it will be found, that he has been enabled thereby to exhibit to his countrymen, and the world generally, a portrait, which, in its more important features, may prove deserving of some share of public regard.

Sir William Forbes, in the introduction to his interesting Account of the Life and Writings of the late Dr. Beattie, reminds his readers, that “Mr. Mason prefaces his excellent and entertaining Memoirs of the Life and Writings of Gray, with an observation more remarkable for its truth than novelty;”[novelty;”] that “the Lives of men of letters seldom abound with incidents.”—“A reader of sense and taste, therefore,” continues Mr. Mason, “never expects to find, in the Memoirs of a Philosopher or Poet, the same species of entertainment or information, which he would receive from those of a Statesman or General. He expects, however, to be informed or entertained. Nor will he be disappointed, did the writer take care to dwell principally on such topics as characterize the man, and distinguish that peculiar part which he acted in the varied drama of society.”

Yet these observations of Mr. Gray’s biographer, though pretty generally correct, admit of some qualification and many exceptions, depending on a variety of circumstances. It is true, that a mere narrative of the life of a “philosopher,” as well as of a “poet,” considered only as such, and abstractedly, must be expected to be devoid of much “incident” that can interest the generality of readers. But, both philosophers and poets have, in some instances, been also statesmen; sometimes, even generals: both have, not unfrequently, distinguished themselves as patriots, and benefactors of mankind.

In writing the life of our philosopher, the plan of a dry recital of only such circumstances and occurrences as have an immediate relation to the individual, has not been pursued. Biographical Memoirs, it is conceived, do not confine a writer to limits so narrow, but permit him to take a much greater latitude. It is even allowable, in works of this kind, to introduce historical facts, memorable events, proceedings of public bodies, notices of eminent men, evidences of the progress and state of literature, science and the arts, and the actual condition of civil society, in the scene that is contemplated; together with occasional reflections on those and similar subjects. Some of these objects may not seem, perhaps, to be necessarily or very intimately connected with the principal design, the life of the person treated of: but such of them as should, at first view, appear to have the most remote relation to that object, may be afterwards discovered to be both useful and interesting in a discussion of this nature; while others serve to elucidate the main scope of the work. A latitude of this description, in the compilation of memoirs, seems to be quite consistent with the genius and spirit of works of that nature; and the modern practice of memoir-writers has been conformable to this view of the subject.[[54]]

The writer of the present work has therefore ventured, with all due deference to the public opinion, to pursue the course here described. And in doing this, he presumes that the comprehensive range he has allowed himself has enabled him to render his memoirs, even of a “philosopher,” not altogether barren of incidents, nor destitute, he trusts, either of pleasing information or useful instruction.


NOTE.—The reader is requested to substitute (with his pen) the word Earth, in the place of “Sun,” in the sixth line of the note numbered ([18]), page xxxii. of the foregoing Introduction: the error in the print is an essential one; and passed unobserved, until it was too late to correct it in the press. At the same time the reader will be pleased to insert the word security, in the place of “scarcity,” in the ninth line from the top of page xlii.
