This publication is published in occasion of the first comprehensive show of the Mexican artist Pedro Reyes in Europe. The trained architect caused an international sensation in 2012 with his large installation "Sanatorium" for the Kassel dOCUMENTA (13). In the accompanying exhibition at Museum Marta Herford, he is showing his extensive sculptural work, which is close to the concept of "social sculpture" - as Joseph Beuys once coined it - and is often reminiscent of political activism. With his projects, he not only poses critical questions, but also develops utopian approaches to solutions for real social problems. In doing so, Reyes incorporates psychological, philosophical, but also sociological and activist methods and encourages people to become active themselves. The term "Societry" was coined by social scientist Jacob Levy Moreno, who developed a series of therapies to heal society. "A social experiment can serve as research and also be therapeutic (and entertaining)." (Pedro Reyes in interview)
