Bell?s book comes with an intriguing picture on its front cover: Gustave Doré?s famous 1860 depiction of a New Zealander perched on a broken arch of London Bridge sketching the ruins of St Paul?s and its environs. The image, derived from an essay by Thomas Babington Macaulay, captures much of the Victorian premonition and anxiety about empire. Schooled on the classics and hardened in the tropics, successive generations of colonial statesmen and commentators in the 19th century learned to hope for little and fear much worse from the possession of far-flung dominion and settlement. Their ultimate nightmare was that the fate of Rome would catch up with Britain, that is, unbridled expansion overseas would precipitate the collapse of civilisation at the metropole. So fashionable had this Gibbonseque trope of ?Macaulay?s New Zealander? become by the 1860s that, according to David Skilton, the satirical magazine Punch called for a proclamation banning its use, along with other proverbial phrases such as ?the Thin End of the Wedge? and ?the British Lion?. As arresting as Doré?s lithograph is, it does seem a slightly odd choice for Duncan Bell?s study, which is devoted to a series of Victorian writers and thinkers who developed a wholly positive vision of empire, looking forward to global peace and order, rather than back to the gloomy lessons of the past. No such problems are presented by the back cover. Gathered there are a series of top scholarly names from both sides of the Atlantic endorsing the book, which has been eagerly anticipated. Derived from his Cambridge PhD thesis of 2004, and trailed in a series of articles and edited collections, The Idea of Greater Britain is one the first major studies of Victorian intellectual life with the subject of the British empire left in, rather than out. Joint winner of the coveted Royal Historical Society?s Whitfield Prize, singled out for praise by Stephen Howe in the Independent, and already frequently cited in new work in the field, it is not just the cover, but the contents of this book, which demand to be noticed. The book is both monograph and manifesto. Bell?s main research task is to resuscitate the somewhat neglected arguments of those Victorians who idealised and proselytised a ?Greater Britain?, that is a closer union of Britain and the settlement colonies. But there is a larger purpose too. Bell calls for historians of political thought in the 19th century to follow their fellow scholars in earlier periods and take empire seriously. He contends that the Victorian canon of thinkers ? so skilfully analysed by, among others, John Burrow, Stefan Collini and Peter Clarke ? has escaped the sort of closer scrutiny which the imperial turn has inspired in intellectual history especially of the 17th and 18th centuries (for example, in the work of Anthony Pagden and David Armitage). By themselves, these two stated purposes are reasonable enough. Although the ?Greater Britain? tendency in the 19th century has not been entirely obscured ? as Bell generously notes, Ged Martin, Michael Burgess and John Kendle have all written about it extensively ? it has tended to be treated as an annex of imperial and commonwealth history rather than part of the main body of the Victorian vision. Moreover, its proponents ? Thomas Carlyle, E. A. Freeman and J. A. Froude to name a few ? have been seen at best as armchair statesmen, and at worst, pedlars of Anglo-Saxon racism. There is also a case for seeing them as misguided romantics, about which Jonathan Mendilow, not cited by Bell, has written. It is good to have the revisionist case put so forcefully, as Bell does so well. And the grander project is welcome too. Whilst 19th-century intellectual historians have not shied away from looking at the connections between India and Victorian political thought (e.g. both James and John Stuart Mill, and Henry Maine), the conceptual place of empire has not been considered in the same way as other Victorian concerns and shibboleths such as liberty, democracy, poverty, the state, or the economy. It is as if, to paraphrase Sir John Seeley, one of the heroes of this study, the British empire was acquired in a fit of absence of thought. Both Bell?s case-study of the Greater Britain movement and his wider claims about the limited horizons of Victorian political thought as a discipline are thus worth considering seriously, separately and in more detail. There is much to commend with both, although there are legitimate concerns about how far the case-study of Greater Britain can really be used to open up new vistas in the intellectual history of the Victorian era.
