Solidarity: A Normative Principle 

The term solidarity has acquired a commendable meaning of mutual responsibility, yet remains suspect because it has been invoked in too broad a spectrum of cultural contexts, ranging from fascist ideology to human rights. This essential book shows how solidarity may be — should be — conceived as a normative principle with pressing legal content, instrumental to the realisation of the social ends of today’s democratic polities. The author, for the first time in such depth, documents the interweaving of legal norms with social ideas and values, focusing on the use of the principle of solidarity in the European Union’s bodies and in its Member States. There are detailed examinations of how the principle appears in such realms as the following: national constitutions;welfare systems;regulation of contracts;social effects of legal rules;women’s rights;the social market economy;the social doctrine of the Catholic Church;affirmation of corporate social responsibility; andsustainability and corporate governance. The author describes how each context contributes to a meaningful elaboration of the concept of solidarity, thus synthesising and extending prior work on the subject. Following Kant’s dictum that the solidarity of mankind is a ‘to be or not to be; a matter of life or death’, in today’s difficult and calamitous times it is appropriate to rethink the principle of solidarity as the reason for living, living fully and not just surviving, in a social agglomeration we call a community. Decoding solidarity, in order to fully understand its potentialities, misrepresentations, and mystifications has therefore become a task entrusted to jurists. For this reason, this matchless book will prove invaluable for lawyers, judges, and policymakers, all of whose professions demand authoritative knowledge of the legal relations among individuals and among legal entities.
