John Stuart Mill (1806?73), a British economist, ethical theorist, and civil servant, was one of the most significant thinkers of the English language throughout the Victorian era. His autobiography, which was released after his death in 1873, details his strict upbringing by a controlling father, his mental health crises when he was twenty, and his battle to find happiness while reflecting on himself and reevaluating notions he had previously believed to be true. The prolific author and thinker's most significant books, including as Principles of Political Economy, On Liberty, Utilitarianism, and The Subjection of Women, have been in print for more than 150 years, and his insights have stood the test of time.
