"In this book, as feminist, Marxist, postcolonial, and queer scholars, we argue that social reproduction is foundational to comprehending urbanization and urban transformations by contributing to the feminist project of writing social reproduction and everyday life into urban theory." Social reproduction is, of course, not just an analytical framing but also an organising call for feminist scholars and our contention is that if we want an urban theory for our time, it needs to be feminist. Feminism is not simply a 'discipline,' 'theory', or 'ideology', but a worldview, a lived praxis that provides a platform for engaged analysis. The book's origins lie in our belief in the necessity of feminist urban knowledge production, a belief further endorsed by our prior critical engagement with the analytical framework of planetary urbanization and our collective ruminations during and post this engagement on the nature of urban theory (Reddy 2018; Ruddick et al. 2018). Not least the considerable response to the theme issue of Society and Space (Peake et al. 2018) showed us that there was an audience desirous of troubling the hegemony of urban theory. Moreover, our approach of working as a team across hierarchies of junior and senior scholars, generations, genders, sexualities, institutions, and disciplines-a praxis we refer to as "the intergenerational social reproductive labor of knowledge production" (Peake et al. 2018, p. 377)-had been fruitful and positive and we wanted it to continue. It was as much a pedagogical experience of reading and writing together, and sharing meals, as it was an exploration of our places within the academy and an intellectual foray into urban theory.
