The second volume of Barbarism and Religion explores the historiography of Enlightenment, and looks at Gibbon's intellectual relationship with writers sucah as Giannone, Voltaire, Hume, Robertson, Ferguson and Adam Smith. Edward Gibbon's intellectual trajectory is both similar but at points crucially distinct from the dominant Latin "Enlightened narrative" these thinkers developed. The interaction of philosophy, erudition and narrative is central to enlightened historiography, and John Pocock again shows how the Decline and Fall is both akin to but distinct from the historiographical context within which Gibbon wrote his great work.
John Greville Agard Pocock was a historian of political thought, best known for his studies of republicanism in the early modern period (mostly in Europe, Britain, and America), his work on the history of English common law, his treatment of Edward Gibbon and other Enlightenment historians, and, in historical method, for his contributions to the history of political discourse. Pocock taught at Washington University in St. Louis from 1966 until 1975, and at Johns Hopkins University in Baltimore from 1975 until 2011.
