"Another world is possible. And the present neoliberal hegemony has tried to convince us that things can only be as they are. Fortunately, this is not the truth. All forms of what we call the “productive engagement to disturb the consensus” are crucial in order to bring to the fore the things that consensus has tried to push aside. Many different voices and people all play a role in the creation of what I call an “agonistic public space”. This is definitely an area where artists, architects or people who are engaged in the field of culture at large play an incredibly important role, because they provide different forms of subjectivities from the ones that already exist."
