To Buchanan's clear head and stout heart, Scotland owes, as England owes likewise, much of her modern liberty. But Scotland's debt to him, it seems to me, is even greater on the count of morality, public and private. What the morality of the Scotch upper classes was like, in Buchanan's early days, is too notorious; and there remains proof enough--in the writings, for instance, of Sir David Lindsay--that the morality of the populace, which looked up to the nobles as its example and its guide, was not a whit better. As anarchy increased, immorality was likely to increase likewise; and Scotland was in serious danger of falling into such a state as that into which Poland fell, to its ruin, within a hundred and fifty years after; in which the savagery of feudalism, without its order or its chivalry, would be varnished over by a thin coating of French "civilisation," and, as in the case of Bothwell, the vices of the court of Paris should be added to those of the Northern freebooter. To deliver Scotland from that ruin, it was needed that she should be united into one people, strong, not in mere political, but in moral ideas; strong by the clear sense of right and wrong, by the belief in the government and the judgments of a living God. And the tone which Buchanan, like Knox, adopted concerning the great crimes of their day, helped notably that national salvation. It gathered together, organised, strengthened, the scattered and wavering elements of public morality. It assured the hearts of all men who loved the right and hated the wrong; and taught a whole nation to call acts by their just names, whoever might be the doers of them. It appealed to the common conscience of men. It proclaimed a universal and God-given morality, a bar at which all, from the lowest to the highest, must alike be judged.
