"Indignate yourself!" It is a liberating and corrosive pamphlet of Stéphane Hessel, French diplomat, former partisan, ninety-three fought that has conquered with this text thousands of readers. In the pages of him Hessel faces the evils of our age and launches a cry that has been able to be heard by becoming a true manifest that overcomes political quarters and ideological divisions. Where are the values handed down from the resistance, where the desire for justice and equality, where the company of progress for everyone? To remind us the things that do not go are the events of a daily life made of injustices and horrors such as wars, violence, massacres. Hessel starts from here, to indicate to everyone what are the reasons why fighting and to keep attention high. The indignation is the first step for a real awakening of the consciences, and the shout of Hessel reminds him with firmness and conviction. To complete the book, the appeal of the former French partisans (of which Hessel is one of the signatories), signed in Paris in March 2004 and the universal declaration of human rights of which Hessel was one of the extensors.
