This paper examines various views of the different dimensions of contemporary historic transition. The authors begin from Boaventura de Sousa Santos' model of a "paradigmatic" transition which should shape a "new common sense". They consider some possible objections to Santos' arguments and try to focus on the consequences and perspectives his model can offer. A review of the views of other contemporary philosophers working in the fields of law, politics, ethics and economy allows them to contextualize Santos' views and some applications of his model. They suggest that Santos' crucial concepts of "regulation" and "emancipation" could be better used in combination with the molar/molecular dichotomy. Finally, they maintain that what we need nowadays is not only a revolution, i.e., a transition from an old paradigm to a new one, but also a "dia-volution", i.e., a revolution of mentality, that enables us to overcome the impasse of incommensurability by considering two paradigms at the same time.
