John Stuart Mill (1806-1873) profoundly influenced the shape of nineteenth century British thought and political discourse. His substantial corpus of works includes texts in logic, epistemology, economics, social and political philosophy, ethics, metaphysics, religion, and current affairs. Among his most well-known and significant are A System of Logic, Principles of Political Economy,On Liberty, Utilitarianism, The Subjection of Women, Three Essays on Religion, and his Autobiography.Mill’s education at the hands of his imposing father, James Mill, fostered both intellectual development (Greek at the age of three, Latin at eight) and a propensity towards reform. James Mill and Jeremy Bentham led the “Philosophic Radicals,” who advocated for rationalization of the law and legal institutions, universal male suffrage, the use of economic theory in political decision-making, and a politics oriented by human happiness rather than natural rights or conservatism. In his twenties, the younger Mill felt the influence of historicism, French social thought, and Romanticism, in the form of thinkers like Coleridge, the St. Simonians, Thomas Carlyle, Goethe, and Wordsworth. This led him to begin searching for a new philosophic radicalism that would be more sensitive to the limits on reform imposed by culture and history and would emphasize the cultivation of our humanity, including the cultivation of dispositions of feeling and imagination (something he thought had been lacking in his own education).
None of Mill’s major writings remain independent of his moral, political, and social agenda. Even the most abstract works, such as the System of Logic and his Examination of Sir William Hamilton’s Philosophy, serve polemical purposes in the fight against the German, or a priori, school otherwise called “intuitionism.” On Mill’s view, intuitionism needed to be defeated in the realms of logic, mathematics, and philosophy of mind if its pernicious effects in social and political discourse were to be mitigated.
In his writings, Mill argues for a number of controversial principles. He defends radical empiricism in logic and mathematics, suggesting that basic principles of logic and mathematics are generalizations from experience rather than known a priori. The principle of utility—that “actions are right in proportion as they tend to promote happiness; wrong as they tend to produce the reverse of happiness”—was the centerpiece of his ethical philosophy. On Liberty puts forward the “harm principle” that “the only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others.” In The Subjection of Women, he compares the legal status of women to the status of slaves and argues for equality in marriage and under the law.
