After the Second World War, American historical writing came under the influence of a consensus school of thought. With occasional, explosive and largely unfruitful exceptions, the general run of American political experience was treated by this 'school' as sustaining a liberal state and as consisting of struggles for place between men of broadly similar ideological persuasions. Louis Hartz epitomized that interpretation in a memorable, if not entirely apposite, remark about the mid-nineteenth century: An instinct of friendship, as it were, was planted beneath the heroic surface of America's political conflict, so that the contenders in it, just as they were about to deliver their most smashing blows, fell into each other's arms. American politics was a romance in which the quarrel preceded the kiss. 1 Hartz and the Handlins produced detailed studies of state government economic policies in nineteenth-century Pennsylvania and Massachusetts which, while allowing for a certain amount of class antagonism, were devoid of any extended consideration of party politics. 2 Such consensus views retain considerable force; America has hardly experienced the ideological battles waged in western Europe since the late eighteenth century. But these views also suffer from an insensitivity to the past as it was actually lived. Perhaps every generation and every community did indeed reach a political consensus. 3 That happy end, however, was not achieved without intense and bitter conflict. 1 Louis Hartz, The Liberal tradition in America (New York, 1955), pp. 139-42. 2 Parties are hardly mentioned at all in important chapters of Louis Hartz, Economic policy and Democratic thought: Pennsylvania, /776-/S66 (Chicago, 1968 edn), chs. v, vii, and of Oscar
