I argue that naturalizing normativity—articulating norms that are appropriate given what we know about ourselves and the world—can be framed in terms of sustainability, calling for norms that underwrite practices of inquiry that make it more rather than less likely that others, especially those who are variously marginalized and subordinated, will be able to acquire knowledge in the future. The case for a sustainable epistemology, with a commitment to attending especially to those in positions of vulnerability, can be made, I (...) argue, as much on epistemic grounds as on grounds of social justice.
