In this provocative work, Lorraine Code returns to the idea of "epistemic responsibility," as developed in her influential 1987 book of the same name, to confront the telling new challenges we now face to know the world with some sense of responsibility to other "knowers" and to the sustaining, nonhuman world. Manufactured Uncertainty focuses centrally on the environmental and cultural crises arising from postindustrial, man-made climate change, which have spawned new forms of passionately partisan social media that directly challenge all efforts to know with a sense of collective responsibility. How can we agree to act together, Code asks, even in the face of inevitable uncertainty, given the truly life-threatening stakes of today's social and political challenges? How can we engage responsibly with those who take every argument for an environmentally grounded epistemology as an unacceptable challenge to their assumed freedoms, comforts, and "rights?" Through searching critical dialogue with leading epistemologists, cultural theorists, and feminist scholars, this book poses a timely challenge to all thoughtful knowers who seek to articulate an expanded and deepened sense of epistemic responsibility-to a human society and a natural world embraced, together, in the most inclusive spirit.
