How do people articulate dissent in conflict-laden situations, such as in an everyday argument or a labor dispute, and how do they justify their actions in order to possibly reach an agreement or at least a viable compromise with the other party? This question is of interest to Luc Boltanski and Laurent Thévenot. Unlike traditional sociology, which attributed the actions of individuals, groups, and classes to objective and hidden forces, Boltanski and Thévenot take seriously the human capacity to navigate such situations and their demands by drawing on various principles of justification that originate from the objective world as well as from different conceptions of the common good. The authors identify six principles that are constitutive for our contemporary society.
