Long considered "non-philosophical,” the letters and novels of women like Catharine Macaulay, Mary Wollstonecraft, and George Eliot have often been omitted from the canon of the Western philosophical tradition. This unfortunate omission is corrected here through Catherine Villanueva Gardner’s thorough discussion of the philosophical importance of their work. Gardner also looks carefully at why letters and novels have been considered this way since they are so prevalent in the work of women in general. Gardner argues that the devaluation or exclusion of certain forms of writing is connected to the biases that underpin the Western ethical tradition. This book is critical reading for courses in introductory philosophy and women’s studies.
