John Stuart Mill was a British philosopher, economist and political theorist, best known for his contribution to the concept of liberty. He was among the first people to justify freedom of individual against state control and advocate women suffrage. Born as the son of the philosopher, historian and economist James Mill, he was trained from early childhood by his father and his friend Jeremy Bentham to carry on the cause of utilitarianism, which they had jointly expounded. To keep him away from distraction, they barred him from mixing with other children, as a result of which he was mostly brought up in adult company, buried in books. So intense was the tutoring, that by the time he reached fourteen, he had gone through Greek and Latin classics and had also studied world history, logic and mathematics as well as the basics of economic theory. However, he soon came out of his father’s shadow and developed his own theories. Subsequently, he began to write extensively on varied subjects, which had far reaching influences across the world.
