Who they are

John Stuart Mill (1806–1873) was an English philosopher and the most important inheritor and reformer of Bentham’s utilitarianism. He revised Bentham’s rather crude mode of utility calculation — that pleasure differs only in quantity, not in quality — proposing that "it is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied," holding that the higher pleasures of the intellectual and spiritual level are qualitatively superior to the lower pleasures of the purely sensory level. In political philosophy his chief work On Liberty systematically argued the proper boundary between individual liberty and social authority, proposing the famous "harm principle": so long as a person’s conduct causes no substantial harm to others, society or government has no right to interfere with his individual choice on the ground that "this is better for him," even if that choice seems to the majority wrong or unwise — a principle still one of the most important theoretical cornerstones of liberal political philosophy’s argument for individual autonomy.

Key stories

A Prodigy’s Education and a Mental Crisis

From childhood Mill received an advanced education under the strict supervision of his father James Mill, learning Greek at three and reading Latin classics at eight, one of the most famous recorded cases of "prodigy education." But this intense intellectual training also brought him, around the age of twenty, a profound mental crisis, sinking him for a time into a long depression, from which he only gradually emerged with the help of poetry and emotional experience — an experience that made his later philosophical thought especially value the worth of emotion and individual difference.

The Boundary of Freedom in the "Harm Principle"

In On Liberty Mill proposed 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" — the individual has absolute autonomy over matters concerning only himself, and society or government has no right to interfere merely because "it would be better for the person" or "the majority disapproves"; this principle is still the most quoted classic formulation in discussing the boundaries of free speech and individual autonomy.
