Harriet Taylor Mill was a prominent British philosopher and advocate of women’s rights. Her extensive body of work is featured in “The Complete Works of Harriet Taylor Mill” and can also be found in “The Collected Works of John Stuart Mill,” particularly in volume XXI.
Harriet Hardy was born in Walworth, south London, to parents Harriet and Thomas Hardy, a surgeon. Educated at home, she showed an early interest in poetry and radical ideas, associating with Unitarian “free thinker” Rev. William Fox.
In 1826, at the age of 18, she married her first husband, John Taylor, with whom she had three children. In 1831, she met John Stuart Mill, likely orchestrated by their mutual interest in women’s rights. Their friendship grew quickly, though it briefly waned for reasons unknown. Mill penned a passionate love letter in French during this period, expressing his desire for their paths to cross again.
After the death of her first husband in 1849, Taylor and John Stuart Mill married in 1851. Taylor had written numerous essays, including joint pieces with Mill on domestic violence and women’s enfranchisement, published in 1851.
During her lifetime, Harriet contributed extensively to the Unitarian journal Monthly Repository and the Society for the Distribution of Useful Knowledge, often anonymously. She co-authored newspaper articles on domestic violence, and Mill credited her as a valuable contributor to his works, including “On Liberty” and “Principles of Political Economy.”
Mill acknowledged her as a joint author of their writings, stating that when thoughts and speculations are shared, the question of originality becomes inconsequential. The extent of their collaboration remains a topic of ongoing debate.
