"The justice of the historian surmounted the habits of the politician; he is much more impartial in his history of the reign of William the Third, than in that of James the Second, or above all, than in the summary of those of Charles the First and Charles the Second. He judges the Whigs of 1692 more severely than the Republicans of 1648; and if I am correctly informed, his new-born impartiality won for him from several interested or ardent Whigs, animated reproaches."
