Different accounts of what it is for something to have a social nature have been given. Sociality does not appear to be a category worthy of philosophical focus, given some of these accounts. If sociality is construed as plural subjecthood, it emerges as a category crucial for our understanding of the human condition. Plural subjects are constituted by a joint commitment of two or more persons to do something as a body. Such commitments generate rights and obligations of a special type, and underlie such phenomena as social conventions, agreements, shared action and social groups on one standard understanding of what these are.

Can it ever be appropriate to feel guilt just because one's group has acted badly? Some say no, citing supposed features of guilt feelings as such. If one understands group action according to my plural subject account of groups, however, one can argue for the appropriateness of feeling guilt just because one's group has acted badly - a feeling that often occurs. In so arguing I sketch a plural subject account of groups, group intentions and group actions: for a group to intend (in the relevant sense) is for its members to be jointly committed to intend that such-and-such as a body. Individual group members need not be directly involved in the formation of the intention in order to participate in such a joint commitment. The core concept of joint commitment is in an important way holistic, not being reducible to a set of personal commitments over which each party holds sway.

It is argued that the English bare plural (an NP with plural head that lacks a determiner), in spite of its apparently diverse possibilities of interpretation, is optimally represented in the grammar as a unified phenomenon. The chief distinction to be dealt with is that between the generic use of the bare plural (as in Dogs bark) and its existential or indefinite plural use (as in He threw oranges at Alice). The difference between these uses is not to be accounted for by an ambiguity in the NP itself, but rather by explicating how the context of the sentence acts on the bare plural to give rise to this distinction. A brief analysis is sketched in which bare plurals are treated in all instances as proper names of kinds of things. A subsidiary argument is that the null determiner is not to be regarded as the plural of the indefinite article a.

Margaret Gilbert explores the phenomenon referred to in everyday ascriptions of beliefs to groups. She refers to this type of phenomenon as "collective belief" and calls the types of groups that are the bearers of such beliefs "plural subjects". I argue that the attitudes that groups adopt that Gilbert refers to as "collective beliefs" are not a species of belief in an important and central sense, but rather a species of acceptance. Unlike proper beliefs, a collective belief is adopted by a group as a means to realizing the group's goals. Unless we recognize that this phenomenon is a species of acceptance, plural subjects will seem prone to change their "beliefs" for irrelevant reasons, and thus frequently appear to act in an irrational manner.

Among other things, this paper considers what so-called collective guilt feelings amount to. If collective guilt feelings are sometimes appropriate, it must be the case that collectives can indeed be guilty. The paper begins with an account of what it is for a collective to intend to do something and to act in light of that intention. An account of collective guilt in terms of membership guilt feelings is found wanting. Finally, a "plural subject" account of collective guilt feelings is articulated, such that they involve a joint commitment to feel guilt as a body.

If there is collective scientific knowledge, then at least some scientific groups have beliefs over and above the personal beliefs of their members. Gilbert's plural-subjects theory makes precise the notion of ‘over and above’ here. Some philosophers have used plural-subjects theory to argue that philosophical, historical and sociological studies of science should take account of collective beliefs of scientific groups. Their claims rest on the premise that our best explanations of scientific change include these collective beliefs. I argue that Gilbert's account of collective scientific belief does not provide a better explanation of scientific change than a non-collective alternative. A different defence of collective scientific belief and knowledge is needed.

The everyday concept of a social group is approached by examining the concept of going for a walk together, an example of doing something together, or "shared action". Two analyses requiring shared personal goals are rejected, since they fail to explain how people walking together have obligations and rights to appropriate behavior, and corresponding rights of rebuke. An alternative account is proposed: those who walk together must constitute the "plural subject" of a goal (roughly, their walking alongside each other). The nature of plural subjecthood, the thesis that social groups are plural subjects, and the relation of these ideas to Rousseau's and Hobbes's, are briefly explored.

The issue of knowing what it means for a group to have collective beliefs is being discussed more and more in contemporary philosophy of the social sciences and philosophy of mind. Margaret Gilbert’s reconsideration of Durkheim’s viewpoint in the framework of the plural subject’s account is one of the most famous. This has implications in the history and the sociology of science—as well asin the history and sociology of philosophy—although Gilbert only outlined them in the former fields and said nothing about the latter. Symmetrically but independently, a historian of science, Mara Beller, has recently challenged Kuhn’s conception of the role of consensus in sciences in a brilliant analysis by carefully studying the history of Copenhagen School of Quantum Mechanics. Not only does she show the role of disagreement and controversies (doubting whether there was any collective belief characteristic in this group of physicists), but she even shakes up the very idea of individual beliefs. Each scientist (Heisenberg, Bohr, etc.) could be seen as divided into several selves. This paper contends that these two conceptions open important new horizons in several domains, especially if they are linked together. The paper assesses this claim in the light of empirical examples like the Vienna Circle, Copenhagen School, and, eventually, Cartesian philosophy. Key Words: plural subject • polyphony • collective briefs • Cartesian argumentation.

Do people have obligations by virtue of the fact that a given country is their country? Actual contract theory says they do because they have agreed to act in certain ways. Contemporary philosophers standardly object in terms of the 'no agreement' objection and the 'not morally binding' objection. I argue that the 'not morally binding' objection is not conclusive. As for the 'no agreement' objection, though actual contract theory succumbs, a closely related plural subject theory of political obligation does not. Plural subject theory may be the truth in actual contract theory and should be explored in its stead.
