A nearer examination, however, will convince every candid enquirer, that individual character exercises, if not a paramount, yet a very powerful influence on human affairs. Whoever investigates minutely any period of history will find, on the one hand, that general causes affecting the whole of society are in constant operation; and on the other, that these general causes themselves are often set in motion, or directed in their effects, by particular men. Thus, of what efficacy were the constancy of Pitt, the foresight of Burke, the arm of Nelson, the wisdom of Wellington, the genius of Wellesley, in bringing to maturity the British empire, and spreading the Anglo-Saxon race, in pursuance of its appointed mission, over half the globe! What marvellous effect had the heroism and skill of Robert Bruce upon the subsequent history of Scotland, and, through it, on the fortunes of the British race! Thus biography, or the deeds or thoughts of illustrious men, still forms a most important, and certainly the most interesting, part even of general history; and the perfection of that noble art consists, not in the exclusive delineation of individual achievement, or the concentration of attention on general causes, but in the union of the two in due proportions, as they really exist in nature, and determine, by their combined operation, the direction of human affairs. The talent now required in the historian partakes, accordingly, of this two-fold character. He is expected to write philosophy and biography: skill in drawing individual character, the power of describing individual achievements, with a clear perception of general causes, and the generalizing faculty of enlarged philosophy. He must combine in his mind the powers of the microscope and the telescope; be ready, like the steam-engine, at one time to twist a fibre, at another to propel an hundred-gun ship. Hence the rarity of eminence in this branch of knowledge; and if we could conceive a writer who, to the ardent genius and descriptive powers of Gibbon, should unite the lucid glance and just discrimination of Robertson, and the calm sense and reasoning powers of Hume, he would form a more perfect historian than ever has, or probably ever will appear upon earth.
