Happiness, Justice, and Freedom: The Moral and Political Philosophy of John Stuart Mill delves deeply into Mill's ethical and political theories, arguing that his ideas form a cohesive and robust philosophical framework. Challenging traditional critiques, this book contends that Mill's doctrines provide a more defensible utilitarianism and political liberalism than previously recognized. Central to this analysis are the interconnected concepts of happiness, justice, and freedom, which are explored through the lens of Mill’s nuanced understanding of human well-being, the role of moral rules, and the protection of individual autonomy. By drawing on Mill's psychological theories, his famous "proof" of the Greatest Happiness Principle, and his perspectives on justice and liberty, the book offers fresh insights into his vision of a society that harmonizes individual and collective good. This comprehensive study also situates Mill’s ideas within the broader utilitarian tradition and highlights their relevance for contemporary moral and political philosophy. It examines Mill’s emphasis on higher human capacities, his defense of moral rules in practical decision-making, and his utilitarian justification for rights. The book traces Mill's substantive principles of justice through applications to political, economic, and social issues, including punishment, taxation, and women's rights, demonstrating their enduring significance. Additionally, it underscores the interdependence of Mill’s theories, arguing that his conception of liberty is inseparable from his theory of justice and both are essential to his broader notion of happiness. Ultimately, the work positions Mill as a pivotal figure in the ongoing development of utilitarian thought and a source of valuable insights for addressing modern ethical and political challenges.
