But they are not therefore useless. How Philip disposed his troops at Chaeronea, where Hannibal crossed the Alps, whether Mary blew up Darnley, or Siquier shot Charles XII, and the thousand other questions of the same description, are in themselves unimportant. The inquiry may amuse us, but the decision leaves us no wiser. He alone reads history aright, who, observing how powerfully circumstances influence the feelings and opinions of men, how often vices pass into virtues, and paradoxes into axioms, learns to distinguish what is accidental and transitory in human nature, from what is essential and immutable.
In this respect, no history suggests more important reflections than that of the Tuscan and Lombard commonwealths. The character of the Italian statesman seems, at first sight, a collection of contradictions, a phantom as monstrous as the portress of hell in Milton, half divinity, half snake, majestic and beautiful above, grovelling and poisonous below. We see a man whose thoughts and words have no connection with each other, who never hesitates at an oath when he wishes to seduce, who never wants a pretext when he is inclined to betray. His cruelties spring, not from the heat of blood, or the insanity of uncontrolled power, but from deep and cool meditation. His passions, like well-trained troops, are impetuous by rule, and in their most headstrong fury never forget the discipline to which they have been accustomed. His whole soul is occupied with vast and complicated schemes of ambition, yet his aspect and language exhibit nothing but philosophical moderation. Hatred and revenge eat into his heart; yet every look is a cordial smile, every gesture a familiar caress. He never excites the suspicion of his adversaries by petty provocations. His purpose is disclosed, only when it is accomplished.
