The Oxford Handbook of American and British Women Philosophers in the Nineteenth Century challenges the misconception that there were no female philosophers during this era. It explores the diverse philosophical contributions of women, including those who wrote academic texts, novels, pamphlets, journalism, and activist writings and examines women's contributions to both philosophical movements and topics in social philosophy. It reveals that the nineteenth century was more conducive to women authors than commonly believed and discusses how factors like race and class influenced women's philosophical perspectives. The Handbook corrects the historical narrative and broadens our understanding of philosophy by showcasing the significant contributions of women philosophers.
