This book tells the colorful story of the lives and legacies of the founders of utilitarianism—one of the most influential yet misunderstood philosophies of the past two centuries. Best known for arguing that “it is the greatest happiness of the greatest number that is the measure of right and wrong,” utilitarianism was developed by the radical philosophers, critics, and social reformers William Godwin, Jeremy Bentham, John Stuart Mill, Harriet Taylor Mill, and Henry Sidgwick. Together, they had a profound influence on nineteenth-century reforms. Their work transformed life in ways we take for granted today. Bentham even advocated the decriminalization of same-sex acts, decades before the cause was taken up by other activists. As Bertrand Russell wrote about Bentham in the late 1920s, “There can be no doubt that nine-tenths of the people living in England in the latter part of last century were happier than they would have been if he had never lived.” Yet in part because of its misleading name and the caricatures popularized by figures as varied as Charles Dickens, Karl Marx, and Michel Foucault, utilitarianism is sometimes still dismissed as cold, calculating, inhuman, and simplistic. By revealing the fascinating human sides of the remarkable pioneers of utilitarianism, this book provides a richer understanding and appreciation of their philosophical and political perspectives—one that also helps explain why utilitarianism is experiencing a renaissance today and is again being used to tackle some of the world's most serious problems.
