In the common course of selfish policy, Oliver Cromwell should have cultivated the friendship of foreign powers, or at least have avoided disputes with them, the better to establish his tyranny at home. Had he been only a bad man, he would have sacrificed the honour of the nation to the success of his domestic policy. But, with all his crimes, he had the spirit of an Englishman. The conduct of such a man must always be an exception to vulgar rules. He had abilities sufficient to reconcile contradictions, and to make a great nation at the same moment unhappy and formidable.

It interprets "In the common course of selfish policy, Oliver Cromwell should have cultivated the friendship of foreign powers, or at least have avoided disputes with them, the better to establish his tyranny at home. Had he been only a bad man, he would have sacrificed the honour of the nation to the success of his domestic policy. But, with all his crimes, he had the spirit of an Englishman. The conduct of such a man must always be an exception to vulgar rules. He had abilities sufficient to reconcile contradictions, and to make a great nation at the same moment unhappy and formidable." in the context of "Junius, Letter XLIII (6 February 1771), quoted in The Letters of Junius, ed. John Cannon (1978), p. 226" to mean that wisdom is timeless.
