In this special issue, our aim is to analyse the role of emotions with particular attention to shaping political actions in the face of present challenges to justice. The relationship between the widespread rise of collective emotions and the experience of injustice in our societies is a pressing issue, both in our everyday practice of ethical and political discourse and in philosophical reflection and discussion. Some negative emotions—such as fear, resentment, greed, distrust towards institutions, and disrespect for basic human rights—are (...) often manipulated and amplified. Other, more positive, emotions, such as respect, hope, solidarity, and affinity, often seem to be not enough to give rise to alternative policies. This worldwide problem reflects a deep economic, social, and existential crisis. In this framework, philosophical reflection on emotions can be put fruitfully in dialogue with the contemporary philosophical analysis of collective intentionality and collective agency, which aims at investigating the nature of different types of groups and their main features as well as phenomena such as sense of group membership and group agency. Indeed, it is often argued that collective emotions boost the sense of group belonging in individual members and act to reduce uncertainty in joint actions. In normative terms, feelings such as the rejection of cruelty have been proposed as the foundation of moral equality, and even rationalistic approaches tend to focus on respect first of all as a feeling, as Kant maintained.
