The author examines the life and legacy of James Mill, who assumed Bentham's mantle and became the central strategist of the philosophical radicals. The narrative explores how Mill, alongside figures like Francis Place and David Ricardo, shaped the intellectual landscape of nineteenth-century Britain. The book details the utilitarian campaigns for parliamentary reform, the abolition of sinecures, the restructuring of the criminal law, and the establishment of unsectarian education through the founding of London University. It presents the utilitarian political theory, which sought to eliminate sinister interests through representative government based on the greatest happiness principle.
Furthermore, it covers the fundamental economic doctrines of the school, particularly Malthus's population theory and Ricardo's law of rent, which provided the scientific scaffolding for their policy positions. The movement met fierce resistance from both conservative defenders of the traditional church and state order and romantic critics of industrial capitalism. Ultimately, the utilitarian crusade succeeded in breaking the barriers of traditional obstructionism, though it frequently underestimated the complexity of social realities and the deep-seated attachment of the nation to historical institutions. The author illustrates the triumphs and limitations of a purely rationalist approach to social and political reconstruction.
