Within the last twenty years, historians' views about the significance of ‘Benthamism’ for the development of British government in the nineteenth century have fluctuated pretty widely. In 1948 J. B. Brebner set decisively in motion a movement away from the interpretation, stated in classic but curiously ambivalent form by A. V. Dicey, which made Bentham the philosopher and advocate of an allegedly dominant policy of laissez faire or ‘individualism’. Brebner attacked both legs of Dicey's argument, contending that in the years 1825–70 (which Dicey had identified as the period of individualism) the scale and variety of State intervention were extensive, and that the State intervention of the time ‘in practically all of its many forms was basically Benthamite—Benthamite in the sense of conforming closely to that forbidding, detailed blueprint for a collectivist state, the Constitutional Code’. More recently, some specialists in nineteenth-century administrative history have accepted, and have in some directions extended, one side of Brebner's thesis, but have cast doubt on the other side. Thus, reinforcing Brebner's interpretation of Victorian policy-making, David Roberts has located ‘the origins of the welfare state’ in the period 1832–54, and Oliver MacDonagh has argued that in ‘the middle quarters of the nineteenth-century…(contrary to all expectation and desire) the collectivist system of the present day began to take its shape’. But in developing their themes Roberts and MacDonagh have tended to attach little importance to what Dicey called ‘opinion’—consciously formulated and coherently worked-out beliefs or programmes—and to stress instead the pragmatic responses of politicians and administrators to problems and events.
