She was influenced by the writings of John Stuart Mill and read all of his major works as they were published. In Mill's "Subjection of Women" (1869) she judged the second chapter excoriating the laws which oppress married women "excellent." She was supportive of Mill's parliamentary run, but believed that the electorate was unlikely to vote for a philosopher and was surprised when he won. While Mill served in parliament, she expressed her agreement with Mill's efforts on behalf of female suffrage, being "inclined to hope for much good from the serious presentation of women's claims before Parliament." In a letter to John Morley, she declared her support for plans "which held out reasonable promise of tending to establish as far as possible an equivalence of advantage for the two sexes, as to education and the possibilities of free development", and dismissed appeals to nature in explaining women's lower status. In 1870, she responded enthusiastically to Lady Amberley's feminist lecture on the claims of women for education, occupations, equality in marriage, and child custody.
