A Brilliant Brain

Biography

John Stuart Mill was a British philosopher and economist whose utilitarian ethics and passionate defense of individual liberty profoundly shaped modern political and moral thought. He advanced utilitarian theory beyond his mentor Jeremy Bentham, arguing that higher pleasures of the mind were superior to mere bodily gratification. His On Liberty became a foundational text for individual rights, while The Subjection of Women made him an unexpected champion of gender equality in Victorian England.
