This paper explores the analysis of ability, where ability is to be understood in the epistemic sense—in contrast to what might be called a causal sense. There are plenty of cases where an agent is able to perform an action that guarantees a given result even though she does not know which of her actions guarantees that result. Such an agent possesses the causal ability but lacks the epistemic ability. The standard analysis of such epistemic abilities relies on the notion (...) of action types—as opposed to action tokens—and then posits that an agent has the epistemic ability to do something if and only if there is an action type available to her that she knows guarantees it. We show that these action types are not needed: we present a formalism without action types that can simulate analyzes of epistemic ability that rely on action types. Our formalism is a standard epistemic extension of the theory of “seeing to it that”, which arose from a modal tradition in the logic of action. (shrink)

We extend stit logic by adding a spatial dimension. This enables us to distinguish between powers and opportunities of agents. Powers are agent-specific and do not depend on an agent’s location. Opportunities do depend on locations, and are the same for every agent. The central idea is to define the real possibility to see to the truth of a condition in space and time as the combination of the power and the opportunity to do so. The focus on agent-relative powers (...) and space-relative opportunities firmly roots effectivity of an autonomous choice making agent in a space–time picture. Our space–time view will be classically Newtonian, since we will assume relativistic phenomena do not play a role in agentive effectivity. We show how our semantics naturally distinguishes between different kinds of histories; histories that reflect real possibilities and histories that reflect counterfactual possibilities. Furthermore, we discuss how the spatial picture sheds light on conceptual problems plaguing the central stit property of ‘independence of agency’. At several points in the article we will emphasise and defend the differences with Belnap’s theory of agency in relativistic branching space–times. (shrink)

This paper studies intentional action in stit logic. The formal logic study of intentional action appears to be new, since most logical studies of intention concern intention as a static mental state. In the formalization we distinguish three modes of acting: the objective level concerning the choices an agent objectively exercises, the subjective level concerning the choices an agent knows or believes to be exercising, and finally, the intentional level concerning the choices an agent intentionally exercises. Several axioms constraining the (...) relations between these different modes of acting will be considered and discussed. The side effect problem will be analyzed as an interaction between knowingly doing and intentionally doing. Non-successful action will be analyzed as a weakening of the epistemic attitude towards action. Finally, the notion of ‘attempt’ will be briefly considered as a further weakening in this direction.

We investigate a series of logics that allow to reason about agents' actions, abilities, and their knowledge about actions and abilities. These logics include Pauly's Coalition Logic CL, Alternating-time Temporal Logic ATL, the logic of ‘seeing-to-it-that' (STIT), and epistemic extensions thereof. While complete axiomatizations of CL and ATL exist, only the fragment of the STIT language without temporal operators and without groups has been axiomatized by Xu (called Ldm). We start by recalling a simplification of the Ldm that has been (...) proposed in previous work, together with an alternative semantics in terms of standard Kripke models. We extend that semantics to groups via a principle of superadditivity, and give a sound and complete axiomatization that we call Ldm G. We then add a temporal ‘next' operator to Ldm G, and again give a sound and complete axiomatization. We show that Ldm G subsumes coalition logic CL. Finally, we extend these logics with standard S5 knowledge operators. This enables us to express that agents see to something under uncertainty about the present state or uncertainty about which action is being taken. We focus on the epistemic extension of X-Ldm G, noted E-X-Ldm G. In accordance with established terminology in the planning community, we call this extension of X-Ldm G the conformant X-Ldm G. The conformant X-Ldm G enables us to express that agents are able to perform a uniform strategy. We conclude that in that respect, our epistemic extension of X-Ldm G is better suited than epistemic extensions of ATL. (shrink)

Realism for agents with unconditional beliefs, desires and intentions has been analyzed in modal logic. This paper provides a logical analysis of realism for agents with conditional beliefs and desires in a rule based approach analogous to Reiter's default logic. We distinguish two types of realism, which we call ‘a priori' and ‘a posteriori' realism. We analyze whether these two new properties are compatible with other properties discussed in the literature, such as existence of extensions. We show that Reiter's default (...) logic is too strong, in the sense that a weaker notion of maximality of extensions is needed to satisfy realism. Finally we show that several existing approaches do not satisfy the new realism properties, and we introduce a new construction that does satisfy them. (shrink)

The aim of the work is to provide a language to reason about Closed Interactions, i.e. all those situations in which the outcomes of an interaction can be determined by the agents themselves and in which the environment cannot interfere with they are able to determine. We will see that two different interpretations can be given of this restriction, both stemming from Pauly Representation Theorem. We will identify such restrictions and axiomatize their logic. We will apply the formal tools to (...) reason about games and their regulation. (shrink)

When there are two lines of argument that contradict each other but still end up with the same conclusion, this conclusion is called a floating conclusion. It is an open topic in skeptical defeasible reasoning if floating conclusions ought to be accepted. Inter- estingly, the answer seems to be changing for different examples. In this paper, we propose a solution for explaining the different treatments of the floating conclusion in the various examples from the literature. We collect the examples from (...) the literature, extend them with additional examples and test various hypotheses for explaining the difference by means of the examples. We will argue for a framework that accepts a floating conclusion by default but allows for reasons to deviate from the default in order to reject it. These reasons nicely explain the different underlying patterns of our intuitions. (shrink)

Many philosophers are convinced that rationality dictates that one’s overall set of intentions be consistent. The starting point and inspiration for our study is Bratman’s planning theory of intentions. According to this theory, one needs to appeal to the fulfilment of characteristic planning roles to justify norms that apply to our intentions. Our main objective is to demonstrate that one can be rational despite having mutually inconsistent intentions. Conversely, it is also shown that one can be irrational despite having a (...) consistent overall set of intentions. To overcome this paradox, we argue that it is essential for a successful planning system that one’s intentions are practically consistent rather than being consistent or applying an aggregation procedure. Our arguments suggest that a new type of norm is needed: whereas the consistency requirement focuses on rendering the contents of one’s intentions consistent, our new practical consistency requirement demands that one’s intentions be able to simultaneously and unconditionally guide one’s action. We observe that for intentions that conform to the ‘own-action condition’, the practical consistency requirement is equivalent to the traditional consistency requirement. This implies that the consistency requirement only needs to be amended in scenarios of choice under uncertainty. (shrink)

In Multi Agent Systems it is often the case that individual preferences are not compatible and coalitions compete to achieve a given result. The paper presents a language to talk about the conflict between coalitional choices and it expresses deontic notions to evaluate them. We will be specifically concerned with cases where the collective perspective is at odds with the individual perspective.

Review of Martijn Konings Capital and Time: For a New Critique of Neoliberal Reason. Stanford: Stanford University Press.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Causation Debate in Modern Philosophy: 1637–1739J. A. CoverKenneth Clatterbaugh. The Causation Debate in Modern Philosophy: 1637–1739. New York and London: Routledge, 1999. Pp. xi + 239. Cloth, $75.00. Paper, $21.00.Over the scholastics and earliest moderns, Hume had an advantage of hindsight in declaring that "There is no question, which on account of its importance, as well as difficulty, has caus'd more disputes both among ancients and modern (...) philosophers, than this concerning the efficacy of causes, or that quality which made them be followed by their effects" (Treatise I.iii.14). Between the scholastics and Hume fell (i) Descartes, (ii) classical mechanists such as Hobbes and Gassendi, (iii) the Cartesians Le Grand and Malebranche, (iv) the explanatory rationalists Spinoza and Leibniz, (v) later experimental mechanists such as Boyle, Rohault and Newton, and (vi) the so-called empiricists Locke and Berkeley. This book presents an accessible and admirably broad overview of the modern debate about causation, without sacrificing serious attention to textual details. With two chapters on (i) and one apiece on (ii) - (vi), Clatterbaugh earns for himself and his reader a helpfully synoptic picture of philosophical shifts in the causation debate in the hundred years separating Descartes' Discourse and Hume's Treatise. By the end of the (modern) day, (1) the four-fold causes of Aristotelian-Scholasticism have given way to efficient causation alone; (2) no pre-existing forms in efficient causes are to be found, nor indeed any substantial active powers whatever; (3) there is no deep sense in which causes communicate reality to effects; (4) necessary connection has gone by the board; (5) divine causation has no place in a natural philosophy of causation. No surprises there, but Clatterbaugh's effort reminds us afresh of the varied and torturous routes to such shifts, helping advanced students better (or newly) appreciate them in the comfortable space of 200 pages.Of those pages, a third are devoted to Descartes and the Cartesians. That's not inappropriate, given the importance and difficulty of Descartes's response to Aristotelian-Scholastic accounts of causation, and its influence on occasionalist sentiments on the Continent. The tenor and value of this book may be illustrated by reflecting on the first of these—a rich and frustrating business, both in Descartes's texts and in Clatterbaugh's book. Suppose we grant Descartes the back of his hand to substantial forms and active formal causes as at best "unexplanatory" (counseling Regius): his "at-least-as-much-reality-in-the-cause-as-in-the-effect" principle might be treated as the basis of "an alternative" metaphysical account of causation (19-32). Well, it might be so-treated: but three versions of the principle later, the reader will be excused for judging it little more than a necessary condition for some event-pair x,y counting as a cause-effect pair. If the scholastic appeal to active forms is unexplanatory, then Descartes's [End Page 600] principle—which isn't Descartes's principle at all but a scholastic commonplace—can scarcely fill the explanatory gap. Glossed as a predictable consequence of some strong form of influxus physicus, it is embarrassed by Foucher's objection (that mind bears no likeness to body) and by the weight of texts urging that accidents are individual to their bearers. Having offered us no deep metaphysical story about what in the world answers to 'vis,' Descartes is at best a bungling "interactionist" (here appropriating Clatterbaugh's word for someone whose apparent talk of secondary causes we are asked to respect as expressing a strict and considered philosophical commitment). One can only side with Voetius in reckoning Descartes's replacement of forms by purely quantitative, mechanical principles of motion as expressing a mere "disposition of the movable to move... not an activity of an efficient cause, but merely a necessary condition and a causa sine qua non" (my emphasis: Selectarum Disputationum I [1648-59], 873). Descartes has no deep theory about the nature of causation.Is that too harsh? Had this book a different target, one could fairly complain that the author too infrequently steps away from the texts and commentators to offer and defend a... (shrink)

The impact of smaller firm size on corporate social responsibility (CSR) is ambiguous. Some contend that small businesses are socially responsible by nature, while others argue that a smaller firm size imposes barriers on small firms that constrain their ability to take responsible action. This paper critically analyses recent theoretical and empirical contributions on the size–social responsibility relationship among small businesses. More specifically, it reviews the impact of firm size on four antecedents of business behaviour: issue characteristics, personal characteristics, organizational (...) characteristics and context characteristics. It concludes that the small business context does impose barriers on social responsibility taking, but that the impact of the smaller firm size on social responsibility should be nuanced depending on a number of conditions. From a critical analysis of these conditions, opportunities for small businesses and their constituents to overcome the constraining barriers are suggested. (shrink)

Retrotransposon-derived elements (RDEs) can disrupt gene expression, but are nevertheless widespread in metazoan genomes. This review presents a hypothesis that repressive RNA-binding proteins (RBPs) facilitate the large-scale accumulation of RDEs. Many RBPs bind RDEs in pre-mRNAs to repress the effects of RDEs on RNA processing, or the formation of inverted repeat RNA structures. RDE-binding RBPs often assemble on extended, multivalent binding sites across the RDE, which ensures repression of cryptic splice or polyA sites. RBPs thereby minimize the effects of RDEs (...) on gene expression, which likely reduces the negative selection against RDEs. While mutations that change splice sites in RDEs act as an off-on switch in exon formation, mutations that decrease the multivalency of RBP binding sites resemble a rheostat that enables a more gradual evolution of new RDE-derived exons. RBPs might also repress aberrant processing of active retrotransposons, thus increasing the chance that full-length copies are made. Taken together, in this review, it is proposed that RBPs facilitate the widespread accumulation of intronic RDEs by repressing RNA processing while chaperoning their potential to gradually evolve into new exons.

We introduce the working concept of “affective arrangement.” This concept is the centerpiece of a perspective on situated affectivity that emphasizes relationality, dynamics, and performativity. Our proposal relates to work in cultural studies and continental philosophy in the Spinoza–Deleuze lineage, yet it is equally geared to the terms of recent work in the philosophy of emotion. Our aim is to devise a framework that can help flesh out how affectivity unfolds dynamically in a relational setting by which it is at (...) the same time modulated in recurring ways. With this orientation, this article contributes to the interdisciplinary study of situated affectivity and to the theoretical and conceptual unification of distinct strands of research from several disciplines.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Leibniz & Clarke: A Study of Their Correspondence by Ezio VailatiJan A. CoverEzio Vailati. Leibniz & Clarke: A Study of Their Correspondence. New York and Oxford: Oxford University Press, 1997. Pp. xii + 250. Cloth, $45.00.When Leibniz received the 1710 issue of the Royal Society’s Philosophical Transactions in early 1711, he read John Keill’s public charge that he had stolen the calculus from Newton. Leibniz twice sought amends (...) from the Society in the form of a retraction, in response to which a committee was formed to investigate and issue a report. The resulting Commercium epistolicum, written by the good Isaac Newton himself and condemning Leibniz, was published in early 1713. In Vienna at the time, Leibniz learned of its contents in a June letter from Johann Bernoulli, who complained about this “scarcely civilized way” of holding what was in effect a tribunal from which the chief witness was absent. By year’s end Leibniz had enlisted Wolff to see into print Leibniz’s anonymous statement—overstatement, in fact—of his case, and nine months later Keill replied with an equally overstated rejoinder. Late autumn of 1714 found Leibniz back in Hannover, suffering from gout and the tiresome pressure to advance his work on the history of the house of Brunswick-Lüneburg. If only he felt better and had more free time, he could collect his mathematical papers and set an end to the dispute by writing his own Commercium epistolicum: as it was (Leibniz told Wolff in the spring of 1715), he had no intention of giving Newton’s cronies the luxury of his time.The Leibniz-Clarke exchange began in the shadows of this dispute, contributing to Leibniz’s already established distaste for parts of British philosophy. Already in 1690 he was describing (to Huygens and others) Newton’s gravitational attraction as “inexplicable.” Soon after Leibniz was surprised to discover that Locke had accepted Newtonian attraction in the second edition of the Essay—surprised, at least, until he came to see it as part and parcel of the dangerous idea that God could attach any old property whatever to matter if He chose, including thought. Materialism and frequent miracles [End Page 533] were just around the corner, and from there it was a short distance to the mortality of the soul, and a mean view of God’s power; the decay of natural theology itself could only follow. Leibniz’s misgivings didn’t see the light of day in the early 1700s, when he penned them in the Preface to the Nouveaux Essais; but he went out of his way to work an explicit complaint about Mr. Newton and Mr. Locke into the Théodicée of 1710 (§19 of the Preliminary Discourse). The calculus dispute followed. By the time Leibniz got round to writing Princess Caroline about the dispute in a letter of May 1715, he was insisting that the Newtonians deserved public censure, and that the Britons deserved Leibniz as historiographer of England. For her own part, Caroline now wondered if Samuel Clarke, who had translated Newton’s Opticks into Latin, would in the end be unbiased enough to translate Leibniz’s Théodicée into English. Moreover Caroline doubted that Clarke’s notion of the soul was theologically innocent. Replying in November, Leibniz summarized his view that natural religion was in great decline in England, and the famous exchange began.Despite there being no monograph devoted to it until now, the Correspondence ıs (and was) famous. If a book-length study is overdue, so perhaps are three reminders—that a significant portion of the Correspondence is devoted to issues other than space and time and gravitation, that the depth to which its issues are pursued was compromised by impatience on the side of both parties, and that Clarke’s philosophical views aren’t so well-understood as Leibniz’s own. Nowhere does Vailati set out to make these points explicitly, but they emerge over the course of his book, and together with exegetical soundness are its chief contributions. While this volume makes no historical or philosophical waves, it indirectly (perhaps unwittingly) explains why none are readily forthcoming in a book... (shrink)

This paper develops axiomatic foundations for a probabilistic-interventionist theory of causal strength. Transferring methods from Bayesian confirmation theory, I proceed in three steps: I develop a framework for defining and comparing measures of causal strength; I argue that no single measure can satisfy all natural constraints; I prove two representation theorems for popular measures of causal strength: Pearl's causal effect measure and Eells' difference measure. In other words, I demonstrate these two measures can be derived from a set of plausible (...) adequacy conditions. The paper concludes by sketching future research avenues. (shrink)

How should we construe the unity, in affective experience, of felt bodily changes on the one hand and intentionality on the other, without forcing affective phenomena into a one-sided theoretical framework such as cognitivism? To answer this question, I will consider the specific kind of self-awareness implicit in affectivity. In particular, I will explore the idea that a bodily sense of ability is crucial for affective self-awareness. Describing the affective ways of “grasping oneself” manifest in a person’s felt sense of (...) ability will help us understand the intimate connection between bodily feelings and intentionality in affective processes. In order to illustrate these experiential structures in a concrete case, I will discuss experiential changes often reported by sufferers of depression. (shrink)

The neurosciences not only challenge assumptions about the mind’s place in the natural world but also urge us to reconsider its role in the normative world. Based on mind-brain dualism, the law affords only one-sided protection: it systematically protects bodies and brains, but only fragmentarily minds and mental states. The fundamental question, in what ways people may legitimately change mental states of others, is largely unexplored in legal thinking. With novel technologies to both intervene into minds and detect mental activity, (...) the law should, we suggest, introduce stand alone protection for the inner sphere of persons. We shall address some metaphysical questions concerning physical and mental harm and demonstrate gaps in current doctrines, especially in regard to manipulative interferences with decision-making processes. We then outline some reasons for the law to recognize a human right to mental liberty and propose elements of a novel criminal offence proscribing severe interventions into other minds. (shrink)

BackgroundSharing de-identified individual-level health research data is widely promoted and has many potential benefits. However there are also some potential harms, such as misuse of data and breach of participant confidentiality. One way to promote the benefits of sharing while ameliorating its potential harms is through the adoption of a managed access approach where data requests are channeled through a Data Access Committee (DAC), rather than making data openly available without restrictions. A DAC, whether a formal or informal group of (...) individuals, has the responsibility of reviewing and assessing data access requests. Many individual groups, consortiums, institutional and independent DACs have been established but there is currently no widely accepted framework for their organization and function.Main textWe propose that DACs, should have the role of both promotion of data sharing and protection of data subjects, their communities, data producers, their institutions and the scientific enterprise. We suggest that data access should be granted by DACs as long as the data reuse has potential social value and provided there is low risk of foreseeable harms. To promote data sharing and to motivate data producers, DACs should encourage secondary uses that are consistent with the interests of data producers and their own institutions. Given the suggested roles of DACs, there should be transparent, simple and clear application procedures for data access. The approach to review of applications should be proportionate to the potential risks involved. DACs should be established within institutional and legal frameworks with clear lines of accountability, terms of reference and membership. We suggest that DACs should not be modelled after research ethics committees (RECs) because their functions and goals of review are different from those of RECs. DAC reviews should be guided by the principles of public health ethics instead of research ethics.ConclusionsIn this paper we have suggested a framework under which DACs should operate, how they should be organised, and how to constitute them.

Hypothetico-deductive (H-D) confirmation builds on the idea that confirming evidence consists of successful predictions that deductively follow from the hypothesis under test. This article reviews scope, history and recent development of the venerable H-D account: First, we motivate the approach and clarify its relationship to Bayesian confirmation theory. Second, we explain and discuss the tacking paradoxes which exploit the fact that H-D confirmation gives no account of evidential relevance. Third, we review several recent proposals that aim at a sounder and (...) more comprehensive formulation of H-D confirmation. Finally, we conclude that the reputation of hypothetico-deductive confirmation as outdated and hopeless is undeserved: not only can the technical problems be addressed satisfactorily, the hypothetico-deductive method is also highly relevant for scientific practice.

The goal of our article is to review the widespread anthropological figure, according to which we can achieve a better understanding of humans by contrasting them with animals. This originally Herderian approach was elaborated by Arnold Gehlen, who characterized humans as “deficient beings” who become complete through culture. According to Gehlen, humans, who are insufficiently equipped by instincts, indirectly stabilize their existence by creating institutions, i.e., complexes of habitual actions. On the other hand, Maurice Merleau-Ponty shows that corporeal relationship to (...) the world is already indirect because it is based on preestablished and readjusted “standards” or “norms” of interaction with the environment. Merleau-Ponty then calls these norms “institutions” and views culture as readjustment of institutions which operate already on the level of corporeal existence. The anthropological figure of confronting humans and animals thus cannot produce, as in Gehlen, a contrast between an allegedly “direct” relationship to the world in animals and a supposedly “indirect” relationship to the world in humans. The Herderian approach can be meaningfully retained only if interpreted as an invitation to confront the norms of indirect interaction with the world in animals and in people, that is, if viewed as a comparison of their respective institutions.

This paper presents a critique of left republican writings from a non-republican socialist standpoint. It examines three claims that have been advanced by left republican authors: that workers are dominated 1) by their lack of access to the means of production; 2) by the market; and 3) by their employer. With regard to 1) and 2), it argues that alternative conceptions of freedom can identify the unfreedom in question, and that there are good reasons for pressing these complaints on the (...) basis of these alternative conceptions. With regard to 3), it argues that, while alternative conceptions of freedom may be able to identify the unfreedom in question, republican freedom provides a more suitable basis for pressing this claim. It concludes that while left republicans have shown that socialists have reason to care about republican freedom, they have not shown that socialists should adopt republican freedom at the expense of other conceptions of freedom.

No Longer Patient: Feminist ethics and health care by Susan Sherwin. Philadelphia: Temple University Press, 1992.

Epidemiological research is subject to an ethics review. The aim of this qualitative review is to compare existing ethical guidelines in English for epidemiological research and public health practice in regard to the scope and matter of an ethics review. Authors systematically searched PubMed, Google Scholar and Google Search for ethical guidelines. Qualitative analysis was applied to categorize important aspects of the an ethics review process. Eight ethical guidelines in English for epidemiological research were retrieved. Five main categories that are (...) relevant to the review of epidemiological research by Institutional Review Boards/Research Ethics Committees were distinguished. Within the scope of main categories, fifty-nine subcategories were analyzed. There are important differences between the guidelines in terms of the scope and matter of an ethics review. Not all guidelines encompass all identified ethically important issues, and some do not define precisely the scope and matter of an ethics review, leaving much to the ethics of the individual researchers and the discretion of IRBs/RECs.
