It may be said that much of the interest of biography, especially of the more familiar sort, is of the nature of gossip; as that of the MEMOIRES POUR SERVIR is of the nature of scandal, which is no doubt true. But both gossip and scandal illustrate the strength of the interest which men and women take in each other's personality; and which, exhibited in the form of biography, is capable of communicating the highest pleasure, and yielding the best instruction. Indeed biography, because it is instinct of humanity, is the branch of literature which--whether in the form of fiction, of anecdotal recollection, or of personal narrative--is the one that invariably commends itself to by far the largest class of readers. There is no room for doubt that the surpassing interest which fiction, whether in poetry or prose, possesses for most minds, arises mainly from the biographic element which it contains. Homer's 'Iliad' owes its marvellous popularity to the genius which its author displayed in the portrayal of heroic character. Yet he does not so much describe his personages in detail as make them develope themselves by their actions. "There are in Homer," said Dr. Johnson, "such characters of heroes and combination of qualities of heroes, that the united powers of mankind ever since have not produced any but what are to be found there." The genius of Shakspeare also was displayed in the powerful delineation of character, and the dramatic evolution of human passions. His personages seem to be real--living and breathing before us. So too with Cervantes, whose Sancho Panza, though homely and vulgar, is intensely human. The characters in Le Sage's 'Gil Blas,' in Goldsmith's 'Vicar of Wakefield,' and in Scott's marvellous muster-roll, seem to us almost as real as persons whom we have actually known; and De Foe's greatest works are but so many biographies, painted in minute detail, with reality so apparently stamped upon every page, that it is difficult to believe his Robinson Crusoe and Colonel Jack to have been fictitious instead of real persons.
