Educated with extreme intensity by his father, John Stuart Mill was learning Greek at the age of three. He became the most influential liberal philosopher of the 19th century, defending individual liberty, democracy and equality between the sexes. He served as a member of Parliament and wrote, with Harriet Taylor, pioneering texts on women's rights.

Liberal utilitarianism combines the pursuit of the greatest well-being with a firm defense of individual liberties. Mill refined Bentham's utilitarianism and tied it to political liberalism.
