This paper challenges the common assumption that an agreement is an exchange of promises. Proposing that the performance obligations of some typical agreements are simultaneous, interdependent, and unconditional, it argues that no promise-exchange has this structure of obligations. In addition to offering general considerations in support of this claim, it examines various types of promise-exchange, showing that none satisfy the criteria noted. Two forms of conditional promise are distinguished and both forms are discussed. A positive account of agreements as joint decisions founded in a joint commitment is sketched. It is argued that the example agreements represent especially clearly the normative structure of social union.

This discussion responds to a collection of papers that relate in one way or another to the author’s work in the philosophy of social phenomena. It focuses on those passages that deal most directly with that work. After making some general points that respond to remarks in several of the papers, it turns to the individual papers. The subjects discussed include coordination, conversation, collective beliefs and emotions, joint commitment, obligations and rights, patriotism, promises, the pronoun “we”, and what it is to tell someone something.

In everyday discourse groups or collectives are often said to believe this or that. The author has previously developed an account of the phenomenon to which such collective belief statements refer. According to this account, in terms that are explained, a group believes that p if its members are jointly committed to believe that p as a body. Those who fulfill these conditions are referred to here as collectively believing* that p. Some philosophers – here labeled rejectionists – have argued that collective belief* is not belief but rather acceptance. This paper presents several arguments against rejectionism. One has to do with the proper methodology for arriving at an account of belief. Two address rejectionist claims to the effect that collective beliefs* lack key features of belief in general, the features in question being “aiming at truth” and having a particular relation to the will. A fourth notes that there is a phenomenon more apt for the label of “collective acceptance” than is the phenomenon of collective belief*

Typical agreements can be seen as joint decisions, inherently involving obligations of a distinctive kind. These obligations derive from the joint commitment' that underlies a joint decision. One consequence of this understanding of agreements and their obligations is that coerced agreements are possible and impose obligations. It is not that the parties to an agreement should always conform to it, all things considered. Unless one is released from the agreement, however, one has some reason to conform to it, whatever else is true. In this sense, one is under an obligation to the other parties. The relevance of these points to the issue of political obligation is discussed.

One of the most distinguished living social philosophers, Margaret Gilbert develops and extends her application of plural subject theory of human sociality, first introduced in her earlier works On Social Facts and Living Together. Sociality and Responsibility presents an extended discussion of her proposal that joint commitments inherently involve obligations and rights, proposing, in effect, a new theory of obligations and rights. In addition, it demonstrates the extensive range and fruitfulness of plural subject theory by presenting accounts of social rules, scientific change, political obligation, collective remorse, collective guilt, shared intention and an important class of rights and obligations

This essay explores the nature of an important collective emotion, namely, collective remorse. Three accounts of collective remorse are presented and evaluated. The first involves an aggregate of group members remorseful over acts of their own associated with their group's act; the second an aggregate of persons remorseful over their group's act. The third account posits, in terms that are explained, a joint commitment of a group's members to constitute as far as is possible a single remorseful body. Construed according to this account the remorse of a nation that has wronged another nation is liable to make a particularly important contribution to international peace.
