Various sources in the literature claim that the deduction theorem does not hold for normal modal or epistemic logic, whereas others present versions of the deduction theorem for several normal modal systems. It is shown here that the apparent problem arises from an objectionable notion of derivability from assumptions in an axiomatic system. When a traditional Hilbert-type system of axiomatic logic is generalized into a system for derivations from assumptions, the necessitation rule has to be modified in a way that (...) restricts its use to cases in which the premiss does not depend on assumptions. This restriction is entirely analogous to the restriction of the rule of universal generalization of first-order logic. A necessitation rule with this restriction permits a proof of the deduction theorem in its usual formulation. Other suggestions presented in the literature to deal with the problem are reviewed, and the present solution is argued to be preferable to the other alternatives. A contraction-and cut-free sequent calculus equivalent to the Hubert system for basic modal logic shows the standard failure argument untenable by proving the underivability of DA from A. (shrink)

We study whether robots can satisfy the conditions of an agent fit to be held morally responsible, with a focus on autonomy and self-control. An analogy between robots and human groups enables us to modify arguments concerning collective responsibility for studying questions of robot responsibility. We employ Mele’s history-sensitive account of autonomy and responsibility to argue that even if robots were to have all the capacities required of moral agency, their history would deprive them from autonomy in a responsibility-undermining way. (...) We will also study whether humans and technological artifacts like robots can form hybrid collective agents that could be morally responsible for their actions and give an argument against such a possibility.

Endorsing the idea of group knowledge seems to entail the possibility of group belief as well, because it is usually held that knowledge entails belief. It is here studied whether it would be possible to grant that groups can have knowledge without being committed to the controversial view that groups can have beliefs. The answer is positive on the assumption that knowledge can be based on acceptance as well as belief. The distinction between belief and acceptance can be seen as (...) a refinement of the ordinary language concept of belief, and it may be useful in understanding the nature of epistemic justification and classifying various types of epistemic subjects.

Epistemic justification of non-summative group beliefs is studied in this paper. Such group beliefs are understood to be voluntary acceptances, the justification of which differs from that of involuntary beliefs. It is argued that whereas epistemic evaluation of involuntary beliefs can be seen not to require reasons, justification of voluntary acceptance of a proposition as true requires that the agent, a group or an individual, can provide reasons for the accepted view. This basic idea is studied in relation to theories (...) of dialectical justification in which justification is taken to require ability to justify. Since the reasons offered can in principle always be challenged, there is no ultimate end to the dialectical chain of justification. This makes justification of acceptance, and thus group belief, social and, in a way, contextual, but this does not seem to entail strong forms of epistemic relativism. (shrink)

This paper presents a case study of a psychiatric intervention as an example of an institutional ethnography of psychiatric work. Institutional ethnography, a mode of inquiry outlined by Dorothy Smith (1987), is conceived here as an approach to the analysis of work in institutions as the contingent, local and context-bound insertion of a particular "case" - a patron, a pupil, a client, a patient - into both institutional and other social (e. g. gender, class) relations. The case presented in this (...) paper, shows how a psychiatric factual account is the outcome of a process of the recognition, and/or the production, of "mentionables," followed by the documentary interpretation of mentionables as symptoms. Subsequently it is demonstrated that, and how, the recognition of mentionables depends on non-professional interpretations which by their nature express other social (such as gender, class, etc.) relations. This description of psychiatric diagnostic work is produced by means of a method of discourse analysis that consists of the juxtaposition of the various institutional texts (the two reports) with the transcript of the interview. An analysis of only the interview data would undoubtedly have resulted in some insights about psychiatric interviewing but would have shown neither how the interview functioned as a stage in the institutional process of (re)writing reports nor how ideological evaluations entered the diagnostic process. On the other hand, an analysis of only the two reports would have resulted in some insights about psychiatric reporting but would not have shown how these reports were produced. (shrink)

A proof-theoretical treatment of collectively accepted group beliefs is presented through a multi-agent sequent system for an axiomatization of the logic of acceptance. The system is based on a labelled sequent calculus for propositional multi-agent epistemic logic with labels that correspond to possible worlds and a notation for internalized accessibility relations between worlds. The system is contraction- and cut-free. Extensions of the basic system are considered, in particular with rules that allow the possibility of operative members or legislators. Completeness with (...) respect to the underlying Kripke semantics follows from a general direct and uniform argument for labelled sequent calculi extended with mathematical rules for frame properties. As an example of the use of the calculus we present an analysis of the discursive dilemma. (shrink)

This volume offers eleven philosophical investigations into our future relations with social robots--robots that are specially designed to engage and connect with human beings. The contributors present cutting edge research that examines whether, and on which terms, robots can become members of human societies. Can our relations to robots be said to be "social"? Can robots enter into normative relationships with human beings? How will human social relations change when we interact with robots at work and at home? The authors (...) of this volume explore these questions from the perspective of philosophy, cognitive science, psychology, and robotics. The first three chapters offer a taxonomy for the classification of simulated social interactions, investigate whether human social interactions with robots can be genuine, and discuss the significance of social relations for the formation of human individuality. Subsequent chapters clarify whether robots could be said to actually follow social norms, whether they could live up to the social meaning of care in caregiving professions, and how we will need to program robots so that they can negotiate the conventions of human social space and collaborate with humans. Can we perform joint actions with robots, where both sides need to honour commitments, and how will such new commitments and practices change our regional cultures? The authors connect research in social robotics and empirical studies in Human-Robot Interaction to recent debates in social ontology, social cognition, as well as ethics and philosophy of technology. -/- The book is a response to the challenge that social robotics presents for our traditional conceptions of social interaction, which presuppose such essential capacities as consciousness, intentionality, agency, and normative understanding. The authors develop insightful answers along new interdisciplinary pathways in "robophilosophy," a new research area that will help us to shape the "robot revolution," the distinctive technological change of the beginning 21st century.

We study whether robots can satisfy the conditions for agents fit to be held responsible in a normative sense, with a focus on autonomy and self-control. An analogy between robots and human groups enables us to modify arguments concerning collective responsibility for studying questions of robot responsibility. On the basis of Alfred R. Mele’s history-sensitive account of autonomy and responsibility it can be argued that even if robots were to have all the capacities usually required of moral agency, their history (...) as products of engineering would undermine their autonomy and thus responsibility.

Ethnomethodological studies of work attempt to examine ordinary activities for the ways in which they exhibit observably and accountably competent work practice as viewed by practitioners. Because it is the analyst's task to describe activities as viewed by practitioners,qua practitioners, two methodical problems must be solved. The first problem is how the analyst can know and describe the members' point of view. Because members display their point of view to each other, the problem can be formulated as the question of (...) how the analyst can identify members' displays. This is theproblem of observability. The second problem is how the analyst can make a distinction between activities done by practitioners, qua practitioners, and other activities. How can the analyst for instance, distinguish talkas work from talkat work? This is theproblem of specificity. This paper's aim is to critically examine the ways in which ethnomethodology manages these two problems. First, the concept of the occasioned corpus of setting features is discussed. Next, two examples of ethnomethodological studies of institutional work are examined. It is argued that these studies fail to provide an adequate description of the specificity of the work studied because both disregard practitioners' orientation to the requirements of institutional accounting and reporting. Finally, it is discussed how practitioners' orientations to institutional criteria can be made observable in the analysis. (shrink)

I will study the concept of solidarity by looking at patterns of practical reasoning leading to behaviour that can be taken to exemplify solidarity. By studying which kinds of premisses are necessary for taking the motivation to display solidarity, in contrast to altruistic or moral motivation, I try to find necessary conditions for solidarity. I will argue that practical reasoning leading to solidary behaviour is a form of we-reasoning in which some of the premisses are in first person plural form (...) and attribute actions or attitudes to a collective. If this is correct, solidarity is a group concept, and intentional solidary behaviour presupposes identification with a group where others have shared goals or interests. This distinguishes solidary motivation and behaviour from altruistic or moral motivation and behaviour. (shrink)

In dialogue with Jürgen Habermas's communicative ethics, Covenant and Communication constructively explores a covenantal-communicative model of Christian ethics. Author Hak Joon Lee analyzes themes of freedom, equality, and reciprocity in Habermas's theory of communication from the perspective of the Reformed Christian doctrines of covenant and the Trinity.

In philosophical action theory there is a wide agreement that intentions, often understood in terms of plans, play a major role in the deliberation of rational agents. Planning accounts of rational agency challenge game- and decision-theoretical accounts in that they allow for rationality of actions that do not necessarily maximize expected utility but instead aim at satisfying long-term goals. Another challenge for game-theoretical understanding of rational agency has recently been put forth by the theory of team reasoning in which the (...) agents select their actions by doing their parts in the collective action that is best for the group. Both planning and team reasoning can be seen as instances of a similar type of reasoning in which actions are selected on the basis of an evaluation of a larger unit than an individual’s momentary act. In recent theories of collective agency, both planning and team reasoning have been defended against orthodox game theory, but, interestingly, by different authors: Raimo Tuomela has defended team reasoning in his theory of group agency, but he ignores temporally extended planning in this context. Michael Bratman has extended his theory of planning to the case of shared agency, but he does not seem to see a role for team reasoning in understanding shared intentional activities. In this paper, we argue that both accounts suffer from this one-sidedness. We aim to combine the main insights of Tuomela’s we-mode approach and Bratman’s planning approach into a fruitful synthesis that we think is necessary for understanding the nature of group agency.

A broad introduction to Christian ethics based on a covenantal understanding of Christian life rooted in Scripture.

The aim of this paper is to present a philosophically inspired list of minimal requirements for social agency that may serve as a guideline for social robotics. Such a list does not aim at detailing the cognitive processes behind sociality but at providing an implementation-free characterization of the capacities and skills associated with sociality. We employ the notion of intentional stance as a methodological ground to study intentional agency and extend it into a social stance that takes into account social (...) features of behavior. We discuss the basic requirements of sociality and different ways to understand them, and suggest some potential benefits of understanding them in an instrumentalist way in the context of social robotics.

We reflect on Raimo Tuomela’s philosophy of social action and group action on the basis of our collaboration in his research group over the years. We will give a brief introduction to Tuomela’s career, his research endeavours, and the development of the field of collective intentionality and social ontology in which he was one of the central figures. We will focus on the development of three central themes in his research: we-intentions, we-reasoning, and collective responsibility.
