Moral duties are regularly attributed to groups. In the media or on the street, we might hear that a specific country has a moral duty to defend human rights, that environmentalists have a moral duty to push for global systemic reform, or that the affluent have a moral duty to alleviate poverty. Do such attributions make conceptual sense or are they mere political rhetoric? And what does that imply for the individual members of these groups? Group Duties offers the first comprehensive answer to these questions. Stephanie Collins defends a Tripartite Model of group duties - so-called because it divides groups into three fundamental categories. First, we have combinations - collections of agents that don't have any goals or decision-making procedures in common. These groups cannot bear moral duties. Instead, we should re-cast their purported duties as a series of duties, one held by each agent in the combination. Each duty demands its bearer to 'I-reason': to do the best they can, given whatever they happen to believe the others will do. Second, there are groups whose members share goals but lack decision-making procedures. These are coalitions. Coalitions also cannot bear duties, but their alleged duties should be replaced with members' several duties to 'we-reason': to do one's part in a particular group pattern of actions, on the presumption that others will do likewise. Third and finally, collectives have group-level procedures for making decisions. They can bear duties. Collectives' duties imply duties for collectives' members to use their role in the collective with a view to the collective doing its duty. With the Tripartite Model in-hand, Collins argues that we can target our political demands at the right entities, in the right way, for the right reasons.

Social epistemology has been flourishing in recent years, expanding and making connections with political philosophy, virtue epistemology, philosophy of science, and feminist philosophy. The philosophy of the social world too is flourishing, with burgeoning work in the metaphysics of the social world, collective responsibility, group action, and group belief. The new philosophical vista now more clearly presenting itself is collective epistemology--the epistemology of groups and institutions. Groups engage in epistemic activity all the time--whether it be the active collective inquiry of scientific research groups or crime detection units, or the evidential deliberations of tribunals and juries, or the informational efforts of the voting population in general--and yet in philosophy there is still relatively little epistemology of groups to help explore these epistemic practices and their various dimensions of social and philosophical significance. The aim of this book is to address this lack, by presenting original essays in the field of collective epistemology, exploring these regions of epistemic practice and their significance for Epistemology, Political Philosophy, Ethics, and the Philosophy of Science.

Working within the traditions of Bion, Turquet, Foulkes and Pines, and drawing on concepts and data from psychoanalysis, group analysis and sociology, this volume develops Earl Hopper's theory of the fourth basic assumption in the unconscious life of groups and group-like social systems within a social, cultural and political context.

The authors give a detailed description of the torsors that correspond to multiloop algebras. These algebras are twisted forms of simple Lie algebras extended over Laurent polynomial rings. They play a crucial role in the construction of Extended Affine Lie Algebras (which are higher nullity analogues of the affine Kac-Moody Lie algebras). The torsor approach that the authors take draws heavily from the theory of reductive group schemes developed by M. Demazure and A. Grothendieck. It also allows the authors to find a bridge between multiloop algebras and the work of F. Bruhat and J. Tits on reductive groups over complete local fields.

In attempting to understand the psychological aspects of the developmental process and socialisation, the distinct disciplines of sociology and psychology were brought together for the first time. Titles in the Sociology of Behaviour and Psychology set of the International Library of Sociology analyse how behaviour is formed and learned.

Research on small groups is highly diverse because investigators who study such groups vary in their disciplinary identifications, theoretical interests, and methodological preferences. The goal of this volume is to capture that diversity, and thereby convey the breadth and excitement of small group research by acquainting students with work on five fundamental aspects of groups. The volume also includes an introductory chapter by the editors which provides an overview of the history of and current state-of-the-art in the field. Together with introductions to each section, discussion questions and suggestions for further reading, make the volume ideal reading for senior undergraduate and graduate students interested in group dynamics.
