Isabelle Aubert: Solidarity and Critical Reason

This presentation aims to show solidarity as a key concept to Critical Theory, especially for Jürgen Habermas and the next generation, Iris Marion Young, and Axel Honneth. In examining their approaches, I will focus on three main issues to reveal the explanatory, normative/critical, and epistemological scope of solidarity. I shall describe the conceptual challenge of getting the definition of solidarity right. Against particularistic forms of solidarity that are sectarian and exclusive, Habermas, Young, and Honneth present three interesting perspectives which stress the importance of a universal and reciprocal solidarity for the inclusion of all in democracy. I will then highlight how solidarity is not merely a descriptive, but also a critical concept. Solidarity refers to a social fact, the absence of which causes serious social pathologies, and it is also a normative issue with moral and political implications. Each following a singular path, Habermas, Honneth and Young reveal how and why the realization of a mutual solidarity is crucial for developing a society in which it is good to live together, not next to each other along parallel tracks or with some people dominating others. My final concern will be to demonstrate the necessary link between solidarity and critical rationality: if a real critique is to be based on social practice, then solidarity between participants must be presupposed to ensure this practice.


Rainer Forst: Solidarity: Concept and Conceptions

This article distinguishes between a general concept and various conceptions of solidarity depending on normative contexts. The general concept of solidarity refers to a particular practical attitude and involves a form of “standing by” each other based on a particular normative bond with others constituted by a common cause or shared identity. Since solidarity is a normatively dependent concept, the nature of such bonds, causes or identities is not determined by the concept. Furthermore, solidarity itself, without the addition of further normative sources, is not a value; it can serve worthy or unworthy causes. Also, on the general conceptual level, the question of whether solidary acts are of a supererogatory nature or presuppose a particular sort of reciprocity or symmetry is left open. These questions have to be dealt with on the level of particular conceptions of solidarity, of which the article distinguishes four general ones: ethical conceptions located in communal contexts based on shared notions of the good, legal conceptions according to which solidary communities and duties are legally constituted, political conceptions that either focus on national solidarity or on the solidary pursuit of concrete aims of justice. Finally, moral conceptions of solidarity are based on some notion of common humanity materializing in particular forms of solidary action. Solidarity comes in many forms and with many justifications and grounds.
