The project tells and reflects the different histories of feminist theory. To this end, conversations are carried out with protagonists who had and have a formative influence on feminist theories. In engaging with these scholars, we wish to delve deeper not only into the ideas and concepts that form the key basis of these theories but also to explore the historical contexts, the collective thinking, political practices and historical controversies that enabled them at the time. The conversations bring forth exigent questions around power, inequality and violence, intersectionality, the relation of sex, gender and sexuality, or the critique of binary thinking. We discuss the contributions of feminism into analyzing and challenging significant differences other than gender – such as race, class, nationality, religion, and caste. The project is rooted in oral history, philosophical exchange, and feminist traditions of collective thinking. It has value for those of us interested in the history of feminist theory and in feminism as a resourceful way of challenging dominant knowledges and creating different ones.
