The main question of the 7th Berlin Biennale is focused on substantial results produced by art. It’s difficult because often artistic imagination is not prepared to create such effects. As in politics, it’s better to work collectively rather than alone. So we decided to ask other art institutions who are interested in the same issues to develop their own research and present it in the framework of the Berlin Biennale or in parallel. We call these activities and their results "Solidarity Actions". Instead of competition, we focus on cooperation with a common horizon. There is a real lack of solidarity in the art world, and we are making a step to change it.
