“For all the young women and girls sitting in philosophy class wondering where the women are, this is the book for you. This collection of 21 chapters, each on a prominent woman in philosophy, looks at the impact that women have had on the field throughout history. From Hypatia to Angela Davis, The Philosopher Queens will be a guide to these badass women and how their amazing ideas have changed the world.
“This book is written both for newcomers to philosophy, as well as all those professors who know that they could still learn a thing or two. This book is also for those many people who have told us that there are no great women philosophers.”
