overpopulation, depletion of resources and environmental degradation. In the 1970s Özbekhan was co founder and first director of The Club of Rome, with Aurelio Peccei an Italian Industrialist, and Alexander Christakis, a physicist and systems research designer. Özbekhan wrote the original prospectus for The Club of Rome, The Predicament of Mankind. This document served as vision for systems scientists who, under the leadership of Alexander Christakis and the 21st Century Agoras developed the science of structured dialogic design. Özbekhan is credited for the formulation of the Axiom of Engagement, which states that 'it is unethical to try to change any socio-technical system without the explicit permission and participation of those involved'. The related Requisite Law of Action states that 'any attempts to do so are bound to fail' (Law of Requisite Action; Yiannis Laouris). Together with Robert Jungk, Johan Galtung and many others he was member of MANKIND 2000.
