John Stuart Mill (1806-73), philosopher, economist, and political thinker, was the most prominent figure of nineteenth-century English intellectual life and his work has continuing significance for contemporary debates about ethics, politics, and economics. His father, James Mill, a close associate of the utilitarian philosopher Jeremy Bentham, assumed responsibility for his eldest son's education, teaching him ancient Greek at the age of three and equipping him with a broad knowledge of the physical and moral sciences of the day.

Mill's Autobiography was written to give an account of the extraordinary education he received at the hands of his father and to express his gratitude to those he saw as influencing his thought, but it is also an exercise in self-analysis and an attempt to vindicate himself against claims that he was the product of hothousing. The Autobiography also acknowledges the substantial contribution made to Mill's thinking and writings by Harriet Taylor, whom he met when he was twenty-four, and married twenty-one years later, after the death of her husband. The Autobiography helps us understand more fully some of the principal commitments that Mill's political philosophy has become famous for, in particular his appreciation of the diversity, plurality, and complexity of ways of life and their possibilities.

This edition of the Autobiography includes additional manuscript materials from earlier drafts which demonstrate the conflicting imperatives that influenced Mill's choice of exactly what to say about some of the most significant episodes and relationships in his life. Mark Philps introduction explores the forces that led Mill to write the "life" and points to the tensions in the text and in Mill's life.
