The trials that make up this volume are offered as a bridge between the conceptions and struggles of the "past" workers' movement (from the nineteenth and twentieth centuries) and the new movements that broke into the "inconclusive revolution" of the 1960s. Caffentzis intends to provide theoretical basis for struggles in a context in which capital mutations obligate - according to an image taken from Frantz fanon- to "stretch" the classic concepts to enlighten them the current forms that exploitation and rejection adopts from work. The work category extends, thus, until reaching a multiplicity of terminals where the exploitation is evened. Or until the work / energy, key to understanding the energy and financial crisis. The concept of original accumulation is also stretched and becomes in progress process: the successive crisis of capitalism demand new fences, with its quotas of violence and dispossession, on earth and on all forms of social life. A renewed way of assuming the class struggle that puts the common problem at the center as a way to face capitalism in its totalitarian phase. A struggle that involves the production and reproduction of life; Solidarity between workers, animal world and nature.
