‘Mental health commoning’ is the work of actively weaving and sustaining communities of collaboration and action around the dimension of life that has to do with psychic suffering. Commoners of radical mental health initiatives manufacture and use resources and goods by collectively creating rules of production and use, improvising and revisiting these rules on an ongoing basis, in response to particular socio-ecological situations. Such initiatives, experiments and practices prefigure new modes of self-governance grounded in the common participation of all people, horizontality, anti-hierarchy, pluralism and openness.
