What is the contribution of General System Theory to the macro-level understanding of economic, social and technological changes in our epoch from a multidimensional perspective? What is the contribution of Social Action Theory on a micro-scale? Can complex scenario analyses, although based upon uncertainty and unpredictability, offer a viable toolkit for managing these transformations?This book contains twelve chapters, dealing with these questions from various points of view. It brings together essays in sociology, economics, law and humanities to provide as complete a representation as possible of the current global situation.The theoretical framework adopted here is that the systemic approach provides the most effective tool both for understanding social phenomena and elaborating policy-modelling strategies for decision makers that are supposed to tackle social criticalities.
