Synopsis Published in 1859, John Stuart Mill's On Liberty presented one of the most eloquent defenses of individual freedom in nineteenth-century social and political philosophy and is today perhaps the most widely-read liberal argument in support of the value of liberty. Mill's passionate advocacy of spontaneity, individuality, and diversity, along with his contempt for compulsory uniformity and the despotism of popular opinion, has attracted both admiration and condemnation. About the Author: John Stuart Mill was born in a suburb of London on May 20, 1806. By the age of ten he was reading classical authors in the original Greek and Latin, was proficient in history, algebra, and geometry, and soon after began to study logic, political economy, and law. He was elected to Parliament in 1865 and held the Radical seat for Westminster for the next three years. Mill died in Avignon, France, on May 7, 1873.
