When in the fullness of time the hour had come for the new experiment in government among men, and it was the fate of the young and feeble colonies upon the coast of the North Atlantic to make the experiment, the Old World was full of the most dismal forebodings as to the result. The world was told that the experiment of democratic government meant the rule of the mob; that it might work well today, but that tomorrow the mob which had had but half a breakfast and could expect no dinner, would take control; and that the tyranny of the mob was worse than the tyranny of any individual. The provisions of our constitutions guard against the tyranny of the mob, for at the time when men can deal in harmony with the principles of justice, when no selfish motive exists, when no excited passions exist, the constitution declares the great principles of justice--that no man shall be deprived of his property without due process of the law; that private property shall not be taken for public use without just compensation; that a person accused of crime shall be entitled to be informed of the charge against him, and given opportunity to defend himself. These provisions are essential to the preservation of liberty; and in the hands of judicial power rests the prerogative of declaring that whenever a congress, or a president, or a general, or whatever officer of whatever rank or dignity infringes, by a hair's breadth, upon any one of these great impersonal declarations of human rights, his acts cease to have official effect. The substitution of the divine quality of judgment, of the judicial quality in man, that quality which is bound by all that honor, by all that respect for human rights, by all that self-respect can accomplish, to lay aside all fear or favor and decide justly--the substitution of that quality for the fevered passions of the hour, for political favor and political hope, for political ambition, for personal selfishness and personal greed,--that is the contribution, the great contribution, of the American Constitution to the political science of the world.
