This book is a tribute to one of the most influential philosophers in the history of philosophy in recent times. With her four-volume work title "A history of Women Philosophers" and the volume of the non-Western history of philosophers, published in 2024, Mary Ellen Waithe's writings have an international significance. Colleagues and friends, who have been companions for many years, have gathered in this book to honor her work. Contributions from the Middle Ages to the present, from the philosophy of religion to logic, cover a broad field that will attract equally broad interest. An otherwise unencountered collection of ideas is presented here, united by the bond of research into the history of women philosophers.
