There had not been a sufficient sifting and criticism of historical materials for a master's work of synthesis. And it is probable that Thucydides lacked a model. Tacitus could indeed have drawn inspiration from the Greek, while Gibbon had lessons from both, showing a profound study of Tacitus and a thorough acquaintance with Thucydides. If circumstances then made it impossible for the Greek or the Roman to attempt history on the grand scale of Gibbon, could Gibbon have written contemporary history with accuracy and impartiality equal to his great predecessors? This is one of those delightful questions that may be ever discussed and never resolved. When twenty-three years old, arguing against the desire of his father that he should go into Parliament, Gibbon assigned, as one of the reasons, that he lacked "necessary prejudices of party and of nation";[56] and when in middle life he embraced the fortunate opportunity of becoming a member of the House of Commons, he thus summed up his experience, "The eight sessions that I sat in Parliament were a school of civil prudence, the first and most essential virtue of an historian."[57] At the end of this political career, Gibbon, in a private letter to an intimate Swiss friend, gave the reason why he had embraced it. "I entered Parliament," he said, "without patriotism, and without ambition, and I had no other aim than to secure the comfortable and honest place of a _Lord of Trade_. I obtained this place at last. I held it for three years, from 1779 to 1782, and the net annual product of it, being L750 sterling, increased my revenue to the level of my wants and desires."[58] His retirement from Parliament was followed by ten years' residence at Lausanne, in the first four of which he completed his history. A year and a half after his removal to Lausanne, he referred, in a letter to his closest friend, Lord Sheffield, to the "abyss of your cursed politics," and added: "I never was a very warm patriot and I grow every day a citizen of the world. The scramble for power and profit at Westminster or St. James's, and the names of Pitt and Fox become less interesting to me than those of Caesar and Pompey."[59]
