In his lively reassessment of extra-parliamentary politics early in the reign of George III, John Brewer advances a conclusion of potentially great significance. Where Sir Lewis Namier and Ian Christie see in Wilkism little more than a political May dance without important effect, Brewer finds a “focussed radicalism” embodying fundamental change in the nature of traditional English politics. Where George Rudé carefully delimits the geographical, social, and political range of Wilkite influence, Brewer argues that “focussed radicalism” was a truly national phenomenon personified in Wilkes and parent to the popular sensibility that underlay later anti-aristocratic and reform politics.
Brewer appears fully as unconventional in his attitude toward what constitutes proper evidence as in the conclusion he builds upon that evidence. Namier and Christie rest their cases on the seemingly solid foundation of election analysis. But Brewer rejects this evidence as inherently unsatisfactory. The “formal, institutional yardstick” of polls, we are told, cannot help measure the influence or extent of radical political opinion. Instead, he concentrates on non-electoral evidence, relying, above all, on the fragile and fleeting indications of support for Wilkes that are to be found in provincial newspapers, petitions, and public gatherings during the years 1768-1771.
