J. G. A. Pocock was educated at the Universities of Canterbury and Cambridge. He is now Harry C. Black Professor of History Emeritus at The Johns Hopkins University and an Honorary Fellow of St John's College, Cambridge. His many seminal works on intellectual history include The Ancient Constitution and the Feudal Law (1957, second edition 1987), Politics, Language and Time (1971), The Machiavellian Moment (1975, second edition 2003), Virtue, Commerce and History (1985), Political Thought and History (2009), and five previous volumes in the Barbarism and Religion sequence, initiated in 1999. He has also edited The Political Works of James Harrington (1977) and Burke's Reflections on the Revolution in France (1987), as well as the collaborative study The Varieties of British Political Thought (1995). A Corresponding Fellow of the British Academy and of the Royal Historical Society, Professor Pocock is also a member of the American Academy of Arts and Sciences and of the American Philosophical Society. He was appointed an Officer of the Order of New Zealand Merit in 2002.

'By uniting civil with ecclesiastical histories, and by describing narratives of antiquity created by, and in a world on the brink of, revolutionary change, Pocock concludes his sixth volume in scholarly territory initially explored by the pioneering work of Arnaldo Momigliano and Franco Venturi, to both of whom the first volume of Barbarism and Religion was dedicated. In his end is his beginning; where Pocock's uniquely authoritative contribution to historical scholarship magisterially concludes, that of many others will surely follow.' B. W. Young, The English Historical Review
