John Stuart Mill

John Stuart Mill was an English philosopher, political economist, and politician. He was a paradigmatic philosopher of liberalism and has been described as "the most influential English-speaking philosopher of the nineteenth century" by the Stanford Encyclopedia of Philosophy. He conceived of liberty as justifying the freedom of the individual in opposition to unlimited state and social control, and formulated the Harm principle. He also advocated proportional representation, the emancipation of women, and the development of labour organisations and farm cooperatives, and has been classified as both a Classical Liberal and Social Liberal.
