Undoubtedly we ought to look at ancient transactions by the light of modern knowledge. Undoubtedly it is among the first duties of a historian to point out the faults of the eminent men of former generations. There are no errors which are so likely to be drawn into precedent, and therefore none which it is so necessary to expose, as the errors of persons who have a just title to the gratitude and admiration of posterity. In politics, as in religion, there are devotees who show their reverence for a departed saint by converting his tomb into a sanctuary for crime. Receptacles of wickedness are suffered to remain undisturbed in the neighbourhood of the church which glories in the relics of some martyred apostle. Because he was merciful, his bones give security to assassins. Because he was chaste, the precinct of his temple is filled with licensed stews. Privileges of an equally absurd kind have been set up against the jurisdiction of political philosophy. Vile abuses cluster thick round every glorious event, round every venerable name; and this evil assuredly calls for vigorous measures of literary police. But the proper course is to abate the nuisance without defacing the shrine, to drive out the gangs of thieves and prostitutes without doing foul and cowardly wrong to the ashes of the illustrious dead. In this respect, two historians of our own time may be proposed as models, Sir James Mackintosh and Mr. Mill. Differing in most things, in this they closely resemble each other. Sir James is lenient. Mr. Mill is severe. But neither of them ever omits, in the apportioning of praise and of censure, to make ample allowance for the state of political science and political morality {278}in former ages. In the work before us, Sir James Mackintosh speaks with just respect of the Whigs of the Revolution, while he never fails to condemn the conduct of that party towards the members of the Church of Rome. His doctrines are the liberal and benevolent doctrines of the nineteenth century. But he never forgets that the men whom he is describing were men of the seventeenth century.
