The theory of free cooperation is an attempt to reconstruct left theory and practice, based on the critique and theoretical inputs by the new social movements of the last decades. It's an answer to the question: If we let go the belief in the "automatical" development of freedom and emancipation through economic progress, the belief in hierarchies, in superficial forms of "democratization" - what is left? How can we build up politics on that, and what does it look like? This will also give new perspectives on the Internet, its power structures and counter-power possibilities.
