This discussion forms part of a project embarked upon many years ago structured around the role of technology in our societies and the way in which we are ostensibly in the process of shifting towards other logics. We are between two states, caught in a process which some call a socio-ecological transition. We are experiencing a period in which two worlds cohabit, together a source of tension and conflict, but also one of manifold innovations and initiatives, some that are promising for the future, others dead-enders. It is from this standpoint that we explore the relevance and operationality of the concept of post-modernity as a means of expressing the shift of our world.
