“It has been our fate as a nation not to have ideologies,” Richard Hofstadter famously wrote, “but to be one.” Defining that “American ideology” or “American creed” obsessed scholars of the consensus era, who celebrated (and occasionally lamented) Americans’ allegiance to a limited liberal vocabulary of rights, freedoms, and markets. The cultural transformations begun in the 1960s seemed to question the very idea of a unitary culture or creed, but some historians responded by exploring alternative ideological founding myths to the liberal consensus. Over the ensuing decades scholars mounted formidable efforts to support republicanism or millennial Christianity as challengers, but liberalism proved a resilient foe. And it seemed to have contemporary history on its side: during the Reagan revolution of the century's final decades the classic liberal combination of scaled-down government and free markets carried the day as Americans’ ideal if not their reality. The Lockean liberal tradition that Louis Hartz described a half-century earlier still appeared the only game in town, although scholars continued to argue over its terms, history, and boundaries.
