This chapter reconstructs the concept of nonviolence. Section one redescribes nonviolence as an ideology, an impure praxis aiming to reinterpret and shape reality. Section two focuses on the core of this ideology. Any nonviolent actor or struggle is based on a certain conviction of human interdependence, which opens up the opportunity for the production of the power of all to foster freedom (as self-restraint and personal responsibility) and plurality (as ethical act and the power of all). Finally, section three aims to rethink principled and pragmatic nonviolence as two families of this ideology. Principled nonviolence focuses on the actualisation of a public principle enhancing self-restraint and openness; pragmatic nonviolence focuses on a phronesis enhancing personal responsibility and the power of all.
