Dominic and Cymene indulge a little post-Pruitt glee on this week’s podcast and speculate about the possibility of six foot tall low carbon lava lamps in the future. Then (16:46) we are thrilled to be joined by star STS scholar and emergent anthropologist María Puig de la Bellacasa to talk about her celebrated new book, Matters of Care: Speculative Ethics in More Than Human Worlds (U Minnesota Press, 2017). We start with the importance of care in feminist philosophy and how this work, alongside her own activist background, inspired this project. She asks us to consider how we can make knowledge that takes seriously a politics of care without giving ourselves over to the neoliberal commodification of care. And she asks how a commitment to speculative ethics can lead us to imagine and enact worlds different than the one we inhabit now. Later on, María tells us about what led her to quit philosophy and why appropriation might not actually be such a bad thing. Then we turn to her work with permaculturalists and soil scientists, what it was like to study with Starhawk, changing paradigms of soil ontology and ecology, what are alterbiopolitics, speculative ethics in a time of political crisis, and so much more.
