The Philosophy of Sociality offers new ideas and conceptual tools for philosophers and social scientists in their analysis of the social world.

This book develops a systematic philosophical theory of social action and group phenomena, in the process presenting detailed analyses of such central social notions as 'we-attitude' (especially 'we-intention' and mutual belief, social norm, joint action, and - most important - group goal, group belief, and group action). Though this is a philosophical work, it presents a unified conceptual framework that may be useful to social scientists, especially social psychologists, as well as philosophers. The book puts forward and defends a number (...) of systematic philosophical theses, resulting in not only a theory of social action but, more broadly, a philosophical theory of society, or at least those aspects of society with which social psychology is supposed to deal (individuals in groups, groups, joint action, and the like).

This paper gives an up-to-date account of we-intentions and responds to some critics of the author’s earlier work on the topic in question. While the main lines of the new account are basically the same as before, the present account considerably adds to the earlier work. For one thing, it shows how we-intentions and joint intentions can arise in terms of the so-called Bulletin Board View of joint intention acquisition, which relies heavily on some underlying mutually accepted conceptual and situational (...) presuppositions but does not require agreement making or joint intention to form a joint intention. The model yields categorical, unconditional intentions to participate in the content of the we-intention and joint intention (viz. shared we-intention upon analysis). The content of a we-intention can be, but need not be a joint action. Thus a participant alone cannot settle and control the content of the intention. Instead the participants jointly settle the content and control the satisfaction of the intention. These and some other features distinguish we-intentions from “action intentions”, viz. intentions that an agent can alone settle and satisfy. The paper discusses weintentions (and other “aim-intentions”) from this perspective and it also defends the author’s earlier account against a charge of vicious circularity that has been directed against it.

In current philosophical research the term 'philosophy of social action' can be used - and has been used - in a broad sense to encompass the following central research topics: 1) action occurring in a social context; this includes multi-agent action; 2) joint attitudes (or "we-attitudes" such as joint intention, mutual belief) and other social attitudes needed for the explication and explanation of social action; 3) social macro-notions, such as actions performed by social groups and properties of social groups such (...) as their goals and beliefs; 4) social norms and social institutions (see Tuomela, 1984, 1995). The theory of social action understood analogously in a broad sense would then involve not only philosophical but all other relevant theorizing about social action. Thus, in this sense, such fields of Artificial Intelligence (AI) as Distributed AI (DAI) and the theory of Multi-Agent Systems (MAS) fall within the scope of the theory of social action. DAI studies the social side of computer systems and includes various well-known areas ranging from Human Computer Interaction, Computer-Supported Cooperative Work, Organizational Processing, Distributed Problem Solving to Simulation of Social Systems and Organizations. Even if I am a philosopher with low artificial intelligence I will below try to say something about what the scope of DAI should be taken to be on conceptual and philosophical grounds. (In the later sections of the paper the central notion of joint intention will be the main topic - in order to illustrate how philosophers and DAI-researchers approach this issue.) Let us now consider the relationship between philosophy - especially philosophy of social action - and DAI. Both are concerned with social matters and in this sense seem to have a connection to social science proper. What kinds of questions should these areas of study be concerned with? In principle, ordinary social science should study all aspects of social life (in various societies and cultures), try to describe it and create general theories to explain it. (shrink)

In this paper the problem of the relation between belief and acceptance is discussed in view of recent literature on the topic. Belief and acceptance are characterized in terms of a number of properties, which show both the similarities and the dissimilarities between these notions. In particular it is claimed - contrary to some recently expressed views - that acceptance need not be intentional action and that the differences between belief and acceptance do not boil down to the simple view (...) that acceptance, contrary to belief, is based on the agent's direct exercise of his will. Acceptance which is not based on intentional action is shown in the paper to be especially closely related to belief, especially to linguistic belief. Thus if a person is in a non-intentional-ly acquired and held state of acceptance that something p, he also believes that p. Another general difference is that acceptance is language-dependent while there can be non-linguistic belief. Collective beliefs and acceptances are also briefly discussed in the paper Among other things, it is noted that the notion of wide as contrasted with truth-oriented, narrow acceptance is central in the collective case.

The main task of the present paper is to investigate the nature of collective knowledge and discuss what kind of justificatory aspects are involved in it to discuss it from collective belief. The central kind of collective knowledge investigated is normatively binding knowledge attributed to a social group. A distinction is made between natural knowledge and constitutive knowledge related to social (especially institutional) matters. In the case of the latter kind of knowledge, in contrast to the former kind, justification and (...) the criteria of justification are purely social. Knowledge is regarded as a primitive, irreducible notion that accordingly does not fall prey to Gettier-type paradoxes. (shrink)

In the paper “We-intentions and Social Action” conceptual issues related to intentional social action are studied. By social actions we here mean actions that are performed together by two or more agents. The central concept of we-intention is introduced and applied to the analysis of simple social practical reasoning. An individualistic analysis of the notion of we-intention is proposed on the basis of the agents’ I-intentions and beliefs. The need and indispensability of we-intentions and we-attitudes in general in a theory (...) of intentional social action is emphasized along with the fact that we-intending leads to action in suitable circumstances. (shrink)

The paper discussed and analyzes collective and joint intentions of various strength. Thus there are subjectively shared collective intentions and intersubjectively shared collective intentions as well as collective intentions which are objectively and intersubjectively shared. The distinction between collective and private intentions is considered from several points of view. Especially, it is emphasized that collective intentions in the full sense are in the “we-mode”, whereas private intentions are in the “I-mode”. The paper also surveys recent discussion in the literature concerning (...) the nature of collective and joint intention and defends the author's accounts against criticisms. (shrink)

In this paper I will discuss a certain philosophical and conceptual program -- that I have called philosophy of social action writ large -- and also show in detail how parts of the program have been, and is currently being carried out. In current philosophical research the philosophy of social action can be understood in a broad sense to encompass such central research topics as action occurring in a social context (this includes multi-agent action); shared we-attitudes (such as we-intention, mutual (...) belief) and other social attitudes expressing collective intentionality and needed for the explication and explanation of social action; social macro-notions, such as actions performed by social groups and properties of social groups such as their goals and beliefs; social practices, and institutions (see e.g. Tuomela, 1995, 2000a, 2001). The theory of social action understood analogously in a broad sense would then involve not only philosophical but all other relevant theorizing about social action. Thus, in this sense, such fields of Artificial Intelligence (AI) as Distributed AI (DAI) and the theory of Multi-Agent Systems (MAS) fall within the scope of the theory of social action. DAI studies the social side of computer systems and includes various well-known areas ranging from human-computer interaction, computer-supported cooperative work, organizational processing, and distributed problem solving to the simulation of social systems.

The paper presents an account of social institutions on the basis of collective acceptance. Basically, collective acceptance by some members of a group involves the members’ collectively coming to hold and holding a relevant social attitude (a “we-attitude”), viz. either one in the intention family of concepts or one in the belief family. In standard cases the collective acceptance must be in the “we-mode”, viz. performed as a group member, and involve that it be meant for the group. The participants (...) must be collectively committed to what they have accepted. Social institutions are taken to be norm-governed social practices introducing a new social and conceptual status on the practices or some elements involved in those practices. This requires that some of the involved norms be constitutive norms as opposed to merely “accidentally” regulating ones. A classification of social institutions is presented. The account is broader in scope than is Searle’s. (shrink)

This volume presents a systematic philosophical theory related to the collectivism-versus-individualism debate in the social sciences. A weak version of collectivism (the "we-mode" approach) that depends on group-based collective intentionality is developed in the book. The we-mode approach is used to account for collective intention and action, cooperation, group attitudes, social practices and institutions as well as group solidarity.

According to the backing law account of causation a singular causal claim is to be analyzed (or “justified”) by reference to a suitable nomic theory which, together with the given singular statement describing a cause, deductively supports or explains the statement describing the effect. This backing law (or deductive-nomological) account of singular causation has recently become the target of several kinds of criticism. First, the possibility of giving a detailed and elaborate account of the required nomic or explanatory backing has (...) been doubted. Secondly, it has been claimed that the deductive-nomological account is bound to lead to unacceptable ontological difficulties (see Kim [1969] and [1973a]). Thirdly, it has been argued that the backing law account fails to give a satisfactory analysis of certain conditional or counterfactual aspects of causation (see Lewis [1973b]). Fourthly, it has been claimed that this approach does not work at least within the social and historical sciences as there are no laws and theories of the required sort to be found there. (shrink)

Many social properties and notions are collectively made. Two collectively created aspects of the social world have been emphasized in recent literature. The first is that of the performative character of many social things (entities, properties). The second is the reflexive nature of many social concepts. The present account adds to this list a third feature, the collective availability or “for-groupness” of collective social items. It is a precise account of social notions and social facts in terms of collective appearance. (...) The collective acceptance account has ontological implications in that it accepts mind-independent, group-dependent, and simply mind-dependent social facts. (shrink)

This is a systematic philosophical and conceptual study of the notion of a social practice. Raimo Tuomela explains social practices in terms of the interlocking mental states of the agents; he shows how social practices are 'building blocks of society'; and he offers a clear and powerful account of the way in which social institutions are constructed from these building blocks as established, interconnected sets of social practices with a special new social status. His analysis is based on (...) the novel concept of shared 'we-attitudes', which represent a weak form of collective intentionality, and he makes instructive connections to major topics and figures in philosophy and the social sciences. His book will be of interest to a wide range of readers in philosophy of mind, philosophy of social science, psychology and sociology, and artificial intelligence. (shrink)

According to scientic realism the ultimate best explanation of the facts and patterns of the framework of common sense or the \manifest image" takes place by showing that these facts and patterns are not real but that they, yet in some sense have counterparts within the scientic image explainable by the best-explaining theories. This explanation can be called eliminative explanation, for it ia part and parcel of this realist idea of explanation that the explananda become eliminated in the process of (...) explanation. The paper investigates some types of realist explanation under the phrase `cor- rective explanation', viz. a correspondence rule account below) and a reinterpretation view ). While in them no elimination directly takes place they can be regarded as being conducive to, and giving reasons for, the ultimate elimination of the explananda. (shrink)
