Pursuing an eclectic program, the Maif Social Club proposes with "Causes always! from hashtag to the street", an exhibition that is thought of as a laboratory of ideas where one comes to crumble one's certainties. As a direct and confusing conversation between Art and Society that questions the influence of the social web on the formation and expression of our commitment to a cause. The exploration is articulated in seven hashtags, each decoded through the prism of an amazing work of art, an enlightening media case and the words of a thinker. With at the centre of the exhibition, the #Ideaux space analyses the multiplication of utopias in the era of the digital revolution. In a nutshell, the same question: should we necessarily choose our cause to the detriment of another? In response, a participatory installation, the voice of a great philosopher and an uplifting video. This polyphonic walk is an invitation to artists, philosophers, sociologists, psychologists, historians and journalists to collectively rethink the world. As we allow ourselves to dream it.
