Nothing so effectually blinds even the naturally clearest sight as moral perversion. Over the very soul of Gibbon, strange to say, this Egyptian darkness brooded so thick, that after intelligently studying this vast, pathetic, and most instructive history, the only practical lesson he drew from it was, that the great corruptor of human society is--_Peace_. He says, 'It was scarcely possible that the eyes of contemporaries should discover in the public felicity the latent causes of decay and corruption. This long peace, and the uniform government of the Romans, introduced a slow and secret poison into the vitals of the Empire,' and the effects of this poison he traces in the 'decline of courage and genius, and in general degeneracy.' Strange that he could imagine that war and bloodshed are the only conceivable prophylactics against self-indulgence, luxury, and unmanly sloth. Within the last few months we have had a remarkable proof of the contrary. For fifty years after Waterloo, Prussia enjoyed profound peace. France, to mention no other wars, had a continual school of war in Algeria. Yet, though the French are as brave as the Germans, they have been unable to stand against them for an hour in the present war; because the tone of the governing class and of the army had been undermined by the moral corruption of the Second Empire. Even if war was indispensable, no man knew better than Gibbon that the Roman frontiers were always in a chronic state of war. The lessons really taught by the history of the Roman Empire during the first century and a half, are so plain that one would hardly have thought they could be missed. Here was a great Empire upon which all the best gifts of God, in the purely natural order, had been poured with a lavish hand. It occupied all the fairest, most fruitful, and most illustrious regions of the globe, to which the climate and situation can never fail to attract intelligent travellers from all less favoured countries. The presiding races of that Empire, which gave their character to all the rest, were those whom God had made His instruments to convey to all nations the best gifts of Nature--the Greek, in whom were stored and preserved the richest powers of genius, art, eloquence and philosophy; the Roman, who has been the example and teacher of all nations, in the great principles of stability, law, and order. For the use and enjoyment of this Empire were stored all the accumulated wealth of literature, poetry, learning, philosophy and art, which all ages of the world had produced and treasured up. To complete the whole, it was exempted for generations together from the scourge of war. In one word, it had everything that God could give to man, except the supernatural gifts of Faith, Hope, and Charity. And the result showed, that, without these, all gifts of the natural order, however precious, were unavailing to preserve human society from utter decay and dissolution.
