The value of solidarity, which implies mutual concern and support, is often conveyed in our everyday moral and political language. But what is its conceptual relationship with justice? Influential positions in this debate may argue for the opposition between the two concepts: justice is impartial and universal, while solidarity is partial and limited. The present paper aims to shortly explore a range of theories that may exemplify possible answers to this position, from communitarian and realist views, which ultimately confirm the (...) opposition, to political solidarities, which claim an instrumental need for solidarity as a reaction to injustices. Special attention will be paid to Habermas’s compatibilist account of solidarity as the “reverse side” of justice. The paper contends that a compelling answer should preserve the difference between the two spheres and the essential features of solidarity by also sketching a concept of solidarity as a social duty arising from our moral interdependence.

ABSTRACT In times of crisis, interpersonal and group solidarity often emerge as people face critical challenges that threaten their survival. However, it remains unclear whether spontaneous solidarity practices are enough to effectively face such crisis situations. In this paper, we argue that to be fully effective, solidarity must be deployed through all its political tiers, from interpersonal and group relationships to institutional and legal normativity. We contend that solidarity relations can only reach an enduring goal if they solidify into stable (...) principles that can be acknowledged and enacted at the institutional level. Through an examination of recent literature and concrete case studies, the paper investigates the linkages and mutual dependencies between the various levels of solidarity developed throughout the COVID-19 pandemic. This analysis may allow us to answer the question of whether a “Multilevel European Solidarity” is a realistic goal, and what is required to achieve it. (shrink)
