Arto Laitinen and Anne Birgitta Pessi have edited a unique collection of essays focusing on the theory and practice of solidarity from a perspective defined by philosophical theories of recognition and emotions on the one hand, and social-scientific work on welfare and helping cultures and practices on the other hand. Authored by leading experts in the field, the volume represents precisely the kind of philosophy enriched by in-depth empirical studies–or empirical social science enriched by philosophical analysis–that we need in the complex social world we live in.
