In this episode, Haley Brennan talks with Alison Stone, professor in the Department of Politics, Philosophy and Religion at Lancaster University. We discuss the work of British women philosophers of the 19th century, including Frances Power Cobbe, Ada Lovelace, and Harriet Martineau. We cover a range of topics that these philosophers worked on, including animal rights, feminism, ethics, and philosophy of mind. In addition to these topics, we talk about the correspondence that these woman had with each other, the influence they had on political movements in 19thc Britain, and where and how to look to find the philosophical writings of women in the period. We also discuss the way that perceived philosophical importance and impact varies across time and place, and how this affects which philosophers we research and teach today.
