For more than a decade the Mexico City–based artist, architect, and cultural agent Pedro Reyes has been turning existing social problems into opportunities for effecting tangible change through collective imagination. By breaking open failed models and retooling them with space to project alternatives, Reyes’s art enables productive diversions of otherwise destructive forces. Ad Usum, To Be Used is the second volume in the series Focus on Latin American Art and Agency, which is dedicated to contemporary cultural agents, a term that is perhaps best understood through the words of Reyes himself: “changing our individual habits has no degree of effectiveness” as “progress is only significant if you start to multiply by 10, by 100, by 1,000.” Rather than merely illustrate his work, this collection of images, interviews, and critical essays is intended as an apparatus for multiplying the possibilities when art becomes a resource for the common good. This full-color illustrated survey of Reyes’s projects includes critical essays by José Luis Falconi, Robin Greeley, Johan Hartle, Adam Kleinman, and Doris Sommer, as well as interviews between the artist and such seminal thinkers as Lauren Berlant, Michael Hardt, Alejandro Jodorowsky, and Antanas Mockus.
