great ascendency over other nations unless the general influence of the dominant State is favorable to civilization; and when this influence is perverted the ascendency passes away. This is remarkably seen in the history of the Persian, the Greek, and the Roman Empires, and still more forcibly in the empire of the popes in the Middle Ages, and of the vast influence of France and England during the last hundred years. This is both a mystery and a fact. It is mysterious that bad men should be allowed to succeed so often, but it is one of the sternest facts of life, only to be explained on the principle that they are instruments in the hands of the Great Moral Governor whose designs we are not able to fathom, yet the wisdom of which is subsequently, though imperfectly, made known. It was wicked in the sons of Jacob to sell Joseph to the Ishmaelites; their craft and lies were successful: they deceived their father and accomplished their purposes; yet his bondage was the means of their preservation from the evils of famine. The rise and fall of empires are to be explained on the same principles as the rise and fall of families. A coarse, unscrupulous but enterprising man gets rich, but his wealth is made to subserve interests far greater than that of his children. Hospitals, colleges, and libraries are endowed as monasteries were in the Middle Ages. If vice, selfishness, and pride were not overruled, what would become of our world? The whole history of civilization is the good which is made to spring out of evil. Men are nothing in comparison with Omnipotence. What are human plans? Yet enterprise and virtue and talent are rewarded. In the affairs of life we see that goodness does not lose its recompense, and that vice is punished; but beyond, what more impressively do we behold than this, that the instruments of punishment are often the wicked themselves.
