This paper discusses how examining the ideas of women philosophers can bring about changes in the study of the history of philosophy. To that end, it reviews Kristin Gjesdal and Dalia Nassar’s (eds.) Women Philosophers in the Long Nineteenth Century: The German Tradition (Oxford University Press, 2021). First, the paper analyzes the significance of the book for the study of the history of philosophy. Second, it explores the contributions of women philosophers by focusing on three chapters from the book that deal with Anne-Louise-Germaine de Staël, Karoline von Günderrode, and Bettina von Arnim. Finally, it attempts to examine the challenges and solutions in developing the study of women’s philosophy.
