As a collaborative work coauthored by a group of anonymous scholars, Speculate This! argues for and embodies affirmative speculation. A short, timely manifesto critiquing predatory modes of financial speculation that seek to minimize uncertainty and risk, while advocating speculative practices that embrace uncertainty, spur radical change, and enable alternative futures. The uncertain commons is a group of scholars, mediaphiles, and activists who explore the possibilities of collaborative intellectual labor. They remain anonymous as a challenge to the current norms of evaluating, commodifying, and institutionalizing intellectual labor. Members of the group represent a diverse set of nationalities, backgrounds, and institutional affiliations, and they participate in a range of disciplines, including cultural studies, English, media studies, philosophy, Middle Eastern studies, and South Asian studies.
