The years of crisis have filled the streets with indignant demonstrators (such as 15-M in Spain) and have been a revulsive that has given rise to new social movements and even new parties. This powerful wave of indignation has shaken many institutions, unleashed great political passions but has also generated a special bewilderment. Times of outrage may also be times of confusion. This book is an attempt to gauge what is valuable in all of this and what its limitations are. Only those who have understood their logic and what politics is in a position to provide us can avoid false expectations and, at the same time, formulate their criticisms in all radicality. This book tries to help us understand politics better because only then can we judge it with all the severity it deserves. In a time of indignation, which questions and criticizes many things that we considered peacefully shared, Daniel Innerarity reviews our idea of politics wondering if we have been right to define its nature, who should do it, what are its possibilities and limits, if some of our common places are still valid, and what can we expect from it. It tries to ensure that this indignation does not remain an unproductive vent, but that it becomes an engine that strengthens politics and improves our democracies.
