Liberty Fund is pleased to make available in paperback eight of the original thirty-three cloth volumes of the Collected Works of John Stuart Mill that were first published by the Universityof Toronto Press that remain most relevant to liberty and responsibility in the twenty-first century. Born in London in 1806 and educated at the knee of his father, the Scottish philosopher James Mill, John Stuart Mill became one of the nineteenth century’s most influential writers on economics and social philosophy. The most indispensable work for understanding Mill’s thought is A System of Logic, Ratiocinative and Inductive, which was the first serious attempt to methodize induction in relation to deduction. John Stuart Mill (1806–1873) was an economist, philosopher, Member of Parliament, and one of the most significant English classical liberals of the nineteenth century. Mill spent most of his working life with the East India Company, which he joined at age sixteen and worked for for thirty-eight years. He is also the author of On Liberty (1859), Utilitarianism (1861), and The Subjection of Women (1869).
