Harriet Taylor Mill

Modern Ethics · Europe · 1807 to 1858

English thinker who argued that women should have the same rights, education and chances as men, and who worked closely with Mill.

What it is

Harriet Taylor Mill (1807 to 1858) was an English writer, philosopher and advocate of women's rights. She was born Harriet Hardy in London, married the wholesaler John Taylor at eighteen and had three children. She is known above all through John Stuart Mill, who praised her wisdom in extravagant terms and credited her with a major share in some of his best-known work.

Her case is unusual. She left no large body of philosophical writing that can be called her own, so what she thought and how much she shaped Mill's ideas must be judged from fragments, from Mill's own words and from what others said about her. Her surviving writing has been gathered in a collection of her own.

The main ideas

  • A partnership of ideas. Mill credited her with a major role in The Principles of Political Economy, On Liberty and "The Enfranchisement of Women", and dedicated On Liberty to her.
  • Women's rights. Wikipedia describes her as an advocate of women's rights, and she is linked with the essay on the enfranchisement of women.
  • The difficulty of the record. Her contemporaries gave very different pictures of her, from "all but unrivaled wisdom" to "a peculiarly affected body".
  • What she wrote. Her own surviving pieces include poems, book reviews and an essay on the aesthetic appreciation of the seasons.
  • A question about credit. Her case raises a general question about how to credit people whose thinking was joined with another's, and who left little in their own name.

What it looks like in practice

Think of a piece of work that two people built together, where one name is on the cover and the other is thanked in the preface. Her case asks how we can tell who thought what, and whether we should trust the credit one partner gave in his own words. This is an illustration of the question her case raises, written by us, not a passage from her writing.

Books and moments

  • The Complete Works of Harriet Taylor Mill gathers her surviving writing.
  • "The Enfranchisement of Women" is an essay in whose creation Mill credits her with a major role.
  • On Liberty, dedicated to her by Mill, is among the works to which he said she contributed greatly.

Questions and criticism

  • Little in her own name. She lacks a substantial body of philosophical work that can uncontroversially be called hers.
  • Two pictures. Mill saw an extraordinary mind, while others who knew her held her in low estimation, and a few judged her a clever woman but not as remarkable as Mill believed.
  • How to judge? It is fair to ask how to assess a thinker whose work is known mainly through the praise of one partner.
