Abstract
After the analysis of evolutionary institutional changes, the fourth chapter will define revolutionary transformations. Revolutions, conceptualized as abrupt processes of social transformation, follow specific life-cycle and result from two main reasons: lack of efficiency and social justice. The chapter is structured as follows. In the first part, the author will provide a general overview of revolutions and revolutionary processes, discussing in detail its main classifications, characteristics and causes, leading actors, overall phases, and outcomes. The second part will outline different revolutionary processes, zooming on scientific revolutions, technology revolutions, and industrial revolutions. There, industrial revolutions and its main elements are investigated in detail, showing how technological innovations lead to dramatic changes of the social reality. By comparing characteristics of the first, second, and third industrial revolutions, there is proposed a model defining the elements of the Fourth Industrial Revolution. Finally, there is discussed a model outlining how of industrial revolutions can change and transform the social institutions.
