Harriet Taylor Mill was born Harriet Hardy in 1807 in
Walworth, south London, to parents Harriet and Thomas Hardy, a surgeon. She was educated at home and expressed an early interest in writing poetry as well as radical and "free thinking" ideas, leading to her association with the congregation of
Unitarian "free thinker"
Rev. William Fox. Taylor Mill married her first husband, John Taylor, in 1826 at the age of 18. Together, they had three children: Herbert, Algernon, and
Helen Taylor. In 1830, Taylor Mill—then Harriet Taylor—met
John Stuart Mill. How they met is the subject of some speculation, but some suggest it was planned by the leader of Taylor's Unitarian congregation. John Taylor invited Mill to dinner because of his wife's mutual interest in women's rights. Taylor was already not only writing poetry, but was interested in social reform, and had written a lengthy
Life of William Caxton (which is, for the most part, a comprehensive history of the printed and written word) for the
Society for the Diffusion of Useful Knowledge. Around the time she met Mill, she was, or began, also writing a series of unpublished pieces on women's rights, ethics, toleration and marriage. Her friendship with Mill quickly blossomed. causing Mill to write her a passionate love letter in French (the only piece of correspondence surviving from either for this period of their relationship) in which he refuses to accept her 'eternal adieu', and, although saying 'her wish is his command', insists 'her path and mine are separated, she says; but they can, they must, meet again'. Evidently, she agreed, for they were soon closer than ever, exchanging a pair of lengthy essays,
On Marriage, in 1833. In these essays, Taylor and Mill discuss the ethical questions of marriage, separation and divorce. Taylor insists that what needs to be done to 'rais[e] the condition of women' is 'to remove all interference with affection, or with anything which is, or which even might be supposed to be, demonstrative of affection'. She criticises the fact that 'women are educated for one single object, to gain their living by marrying'; that 'to be married is the object of their existence'; and 'that object being gained they do really cease to exist as to anything worth calling life or any useful purpose'. She also criticises the hypocrisy and unfairness of the fact that any girl who is seen as 'suitable' for marriage is – because only virgins are seen as suitable – by that very fact completely ignorant as to what marriage entails. She argues for rights to divorce, asking 'who would wish to have the person without the inclination?' and it is noteworthy that Mill is known, in his much-later essay
Utilitarianism, for introducing the concept of differences in the quality of pleasures to a previously quantitative 'hedonic calculus' inherited from
Jeremy Bentham. In late September, or early October 1833, Taylor's husband agreed to a trial separation. She went to Paris where, after what appears to have been an initial onset of cold feet regarding the possible repercussions of such a move for his, and her, reputation, Mill joined her. Despite evidently being extremely happy there with Mill, Taylor was conscience-stricken regarding her husband, keenly feeling the pain, and possible public humiliation, she was putting him through. Eventually, she decided to return to her husband in London, yet by the summer of 1834 she was living in her own house in Keston Heath. Mill visited Taylor frequently at her house in Keston Heath and travelled with her and sometimes her children (particularly in France) throughout the next two decades. ==Marriage to Mill==
