Games, Norms, and Reasons: Logic at the Crossroads provides an overview of modern logic focusing on its relationships with other disciplines, including new interfaces with rational choice theory, epistemology, game theory and informatics. This book continues a series called "Logic at the Crossroads" whose title reflects a view that the deep insights from the classical phase of mathematical logic can form a harmonious mixture with a new, more ambitious research agenda of understanding and enhancing human reasoning and intelligent (...) interaction. The editors have gathered together articles from active authors in this new area that explore dynamic logical aspects of norms, reasons, preferences and beliefs in human agency, human interaction and groups. The book pays a special tribute to Professor Rohit Parikh, a pioneer in this movement. (shrink)

Normativity and the Will collects fourteen important papers on moral psychology and practical reason by R. Jay Wallace, one of the leading philosophers currently working in these areas. The papers explore the interpenetration of normative and psychological issues in a series of debates that lie at the heart of moral philosophy. Themes that are addressed include reason, desire, and the will; responsibility, identification, and emotion; and the relation between morality and other normative domains. Wallace's treatments of these topics are at (...) once sophisticated and engaging. Taken together, they constitute an advertisement for a distinctive way of pursuing issues in moral psychology and the theory of practical reason, and they articulate and defend a unified framework for thinking about those issues. The volume also features a helpful new introduction. (shrink)

Moral obligation is a demand of reason—a demanding kind of rational justification. How to understand this rational demand? Much recent philosophy, as in the work of Scanlon, takes obligatoriness to be a reason-giving feature of an action. But the paper argues that moral obligatoriness should instead be understood as a mode of justificatory support—as a distinctive justificatory force of demand. The paper argues that this second model of obligation, the Force model, was central to the natural law tradition in ethics, (...) is truer to everyday intuition about obligation, and also changes our understanding of the problem of moral rationality. A new account is given of why it might be irrational to breach moral obligations. The Force model also sheds new light on moral responsibility, our responsibility for meeting moral obligations. Moral obligation is a standard of reason; but moral responsibility is shown to involve far more than ordinary rational appraisability, precisely because moral obligation involves a distinctive justificatory force of demand—one which specifically governs how we act. Key Words: blame • moral responsibility • natural law • normativity • obligation • reason. (shrink)

Normativity and the Will collects fourteen important papers on moral psychology and practical reason by R. Jay Wallace, one of the leading philosophers currently working in these areas.The papers explore the interpenetration of normative and psychological issues in a series of debates that lie at the heart of moral philosophy. Part I, Reason, Desire, and the Will, discusses the nexus linking normativity to motivation, including the relations between desire and reasons, the role of normative considerations in explanations of action, (...) and the normative commitments involved in willing an end. Part II, Responsibility, Identification, and Emotion, looks at questions about the rational capacities presupposed by accountable agency and the psychic factors that both inhibit and enable identification with what we do. It includes an interpretation of the Nietzschean claim that ressentiment is among the sources of modern moral consciousness. Part III, Morality and Other Normative Domains, addresses the structure of moral reasons and moral motivation, and the relations between moral demands and other normative domains. Wallace's treatments of these topics are at once sophisticated and engaging. Taken together, they constitute an advertisement for a distinctive way of pursuing issues in moral psychology and the theory of practical reason. The book articulates and defends a unified framework for thinking about those issues, while offering sustained critical discussions of other influential approaches. It should be of interest to every serious student of moral philosophy. (shrink)

The received view of Martin Heidegger’s work is that he leaves little room for reason in the practice of philosophy or the conduct of life. Citing his much-scorned remark that reason is the “stiff-necked adversary of thought”, critics argue that Heidegger’s philosophy effectively severs the tie between reason and normativity, leaving anyone who adheres to his position without recourse to justifying reasons for their beliefs and actions. Transcending Reason is a collection of essays by leading Heidegger scholars that challenges (...) this view by exploring new ways to understand Heidegger’s approach to the relationship between reason, normativity, and the philosophical methodology that gives us access to these issues. The volume points to Heidegger’s novel approach to reason understood in terms of what he calls Dasein’s ‘transcendence’—the ability to occupy the world as a space of normatively structured meanings in which we navigate our striving to be. By examining the strengths and weaknesses of this new and innovative take on Heidegger’s philosophy, this collection considers the possibility that he does not sever but rather reconceives the relation between reason and normativity. -/- .

Discussions of aesthetic reasons and normativity are becoming increasingly popular. This piece outlines six basic questions about aesthetic reasons, normativity, and value and discusses the space of possible answers to these questions. I divide the terrain into two groups of three questions each. First are questions about the shape of aesthetic reasons: what they favour, how strong they are, and where they come from. Second are relational questions about how aesthetic reasons fit into the wider normative (...) landscape: whether they are distinctive, what their normative status is, and how they interact with each other and with non-aesthetic reasons. This piece aims to provide a taxonomy to clarify and organise the burgeoning literature and to make a few concrete suggestions for avenues of future research. (shrink)

In this thesis, I develop and investigate various novel semantic frameworks for deontic logic. Deontic logic concerns the logical aspects of normative reasoning. In particular, it concerns reasoning about what is required, allowed and forbidden. I focus on two main issues: free-choice reasoning and the role of norms in deontic logic. -/- Free-choice reasoning concerns permissions and obligations that offer choices between different actions. Such permissions and obligations are typically expressed by a disjunctive clause in the scope of a (...) deontic operator. For instance, the sentence "Jane may take an apple or a pear" intuitively offers Jane a choice between two permitted courses of action: she may take an apple, and she may take a pear. In the first part of the thesis, I develop semantic frameworks for deontic logic that account for free-choice reasoning. I show that the resulting logics avoid problems that arise for other logical accounts of free-choice reasoning. The main technical contributions are completeness results for axiomatizations of the different logics. -/- Semantic frameworks for deontic logic typically only talk about norms implicitly. In the second part of the thesis, I clarify the role of norms in deontic logic. I develop a formal model of normative systems where norms are represented explicitly. The model takes into account both the hierarchical structure of normative systems, and the function of norms to regulate agent behavior. I show how the model can be used to clarify issues in the study of normative systems. I also develop a norm-based semantics for deontic action logic based on the model. (shrink)

There is an increasing need for norms to be embedded in technology as the widespread deployment of applications such as autonomous driving, warfare and big data analysis for crime fighting and counter-terrorism becomes ever closer. Current approaches to norms in multi-agent systems tend either to simply make prohibited actions unavailable, or to provide a set of rules which the agent is obliged to follow, either as part of its design or to avoid sanctions and punishments. In this paper (...) we argue for the position that agents should be equipped with the ability to reason about a system’s norms, by reasoning about the social and moral values that norms are designed to serve; that is, perform the sort of moral reasoning we expect of humans. In particular we highlight the need for such reasoning when circumstances are such that the rules should arguably be broken, so that the reasoning can guide agents in deciding whether to comply with the norms and, if violation is desirable, how best to violate them. One approach to enabling this is to make use of an argumentation scheme based on values and designed for practical reasoning: arguments for and against actions are generated using this scheme and agents choose between actions based on their preferences over these values. Moral reasoning then requires that agents have an acceptable set of values and an acceptable ordering on their values. We first discuss how this approach can be used to think about and justify norms in general, and then discuss how this reasoning can be used to think about when norms should be violated, and the form this violation should take. We illustrate how value based reasoning can be used to decide when and how to violate a norm using a road traffic example. We also briefly consider what makes an ordering on values acceptable, and how such an ordering might be determined. (shrink)

The development of modern science, as everybody knows, has come largely through naturalizing domains of inquiry that were historically parts of philosophy. Theories based on mere speculation about matters empirical, such as Aristotle‟s view about teleology in nature, were replaced with law-based, predictive explanatory theories that invoked empirical data as supporting evidence. Although philosophers have, by and large, applauded such developments, inquiry into normative domains presents a different set of problems, and there is no consensus about whether such an inquiry (...) can be naturalized. Since the early twentieth century, attempts at naturalizing ethics have been at the center of heated debates, and later attempts at naturalizing epistemology triggered similarly contentious disputes. In ethics, of course, it was not only the Humean and Moorean arguments of early nonnaturalists and noncognitivists that raised doubts about naturalism, but also the arguments of nihilists, who later joined the chorus of criticism, rejecting any ontology that would countenance moral properties and facts. In epistemology, Quinean eliminativism brought reactions that questioned the consistency of naturalism and asked whether it could accommodate the normativity of fundamental epistemic notions such as belief and knowledge. There have so far been no similarly substantial reactions to attempts at naturalizing inquiry into another normative domain, that of reasoning. We hope to remedy that by offering 1 here a response to some recent efforts by experimental philosophers. Experimentalism about reasoning is a radical naturalistic program that rejects reflective-equilibrium accounts of the epistemic grounds for the rules of inference. If we ignore other attempts at justifying those rules a priori by, for instance, appeal to self-evidence, then those invoking Goodmanian reflective equilibrium can be considered the standard analytic accounts (hereafter, „SAA‟). Of concern here is an objection to SAA, the cognitive-diversity argument,1 that is part of a broader experimentalist critique of analytic epistemology.. (shrink)

The thought of Wilfrid Sellars has figured prominently in recent discussions of the relationship between naturalism and normativity . On the one hand, some have appealed to Sellars' philosophy in defence of the thesis that what he called the normative 'space of reasons' is in some sense sui generis and irreducible to the natural causal order described by the natural sciences. On the other hand, others have exploited equally central aspects of Sellars' philosophy in defence of the seemingly incompatible (...) project of attempting to give an exhaustive scientifically naturalist account of mind and meaning, and perhaps of the nature of normativity itself. I contend that what Sellars described as 'the Janus-faced character of languagings as belonging to both the causal order and the order of reasons' ( Naturalism and Ontology ) is the key to understanding his normative and pragmatist variety of naturalism. Sellars saw himself as having articulated a detailed philosophical perspective within which the normative aspects of meaning, knowledge, truth, and representation are themselves opened up, in principle, to naturalistic explanation.

What is one who takes normativity seriously to do if normativity can neither be discovered lurking out there in the world independently of us nor can it be sufficiently grasped from a merely explanatory perspective? One option is to accept that the normative challenge cannot be met and to retreat to some form of moral skepticism. Another possibility has recently been proposed by Christine Korsgaard in The Sources of Normativity where she aims to develop an account of normativity which is (...) grounded in autonomy. Furthermore, she argues that on her account reasons are "essentially public" and that this captures how it is that we can obligate one another. In this paper I argue that there is a serious tension between her account of normativity and the publicity of reasons-namely, that if reasons are essentially public, then it is not possible for individuals to legislate laws for themselves. However, I then argue that if we revise her conception of normativity such that it is understood to involve collective rather than individual legislation that it may then be possible to account for interpersonal reasons.

The main aim of this paper is to identify a type of fact-given warrant for action that is distinct from reason-based justification for action and defend the view that there are two types of practical warrant. The idea that there are two types of warrant is familiar in epistemology, but has not received much attention in debates on practical normativity. On the view that I will defend, normative facts, qua facts, give rise to entitlement warrant for action. But they do (...) not, qua facts, give rise to reason-based warrant. Normative practical reasons, I will argue, are true propositions that represent fact-based favouring and that are made true by normative facts. (shrink)

Ruth Chang has argued convincingly that we must recognize that some choices will not involve strict, univocal comparison of options. How, then, can such choices be made well? Chang suggests that commitment is a fundamental way of ‘putting one's very self’ behind a normative consideration, thereby ‘endow[ing] that consideration with the normativity of a reason’. This view challenges what Chang deems to be three dogmas of normativity, and the current comment critically assesses the relation of her view to the first (...) and third of these dogmas. I suggest some alternative ways of thinking about these dogmas, which enable us to see how her work might uncover a fourth dogma, and which can, I believe, lend strength to a position very close to Chang's.

Logic, considered as a technical discipline inaugurated by Aristotle and typically represented by the variety of the modern logical calculi, constitutes a clarification and refinement of a conviction and practice present in common sense, that is, the fact that humans believe that truth can be acquired not only by immediate evidence, but also by means of arguments. As a first step logic can be seen as a “descriptive” record of the main forms of the arguments present in common sense, but (...) the fact that some of these patterns can actually allow for the derivation of false consequences from true premises imposes the task of making explicit what patterns correspond to a “correct reasoning” and what not. At this point logic appears endowed with a “normative” characteristic. This amounts to saying that logical calculi are intended to adequately mirror the intuitive notion of “logical consequence” and in this sense they cannot be totally arbitrary or conventional, but must satisfy certain basic requirements such as the conditions of soundness and of semantic completeness. In such a way they are “judged” according to the fundamental requirements present at the level of common sense and appear as “idealizations” of the kinds of reasoning practiced in common sense. For this reason also several kinds of logical calculi are fully justified since they make explicit in an idealized form the concrete ways of reasoning that are imposed by the particular domain of reference of the discipline in which they are used and which are basically recognized in common sense.

In this essay I consider the normative implications of the notion of reasonability for the construction of an idea of public reason that is cosmopolitan in scope. First, I consider the argument for the distinction between reason and reasonability in the work of Sibley and Rawls. Second, I evaluate the normative implications of reasonability through a consideration of Korsgaard's recent work. Third, I argue for a notion of reasonability that moves us beyond a Kantian concept of autonomy through a consideration (...) of the relationship between reasonability and judgment vis-à-vis Arendt's work on Kant's Third Critique. Finally, I argue for a cosmopolitan appropriation of the notion of reasonability based on Kant's notion of the aesthetic idea. The latter argument relaxes the bonds of public reason, moving us beyond the domain of ethnocentricism. (shrink)

The critics in this volume raise several important challenges to the modal normativist position developed in Norms and Necessity, including whether the relation I claim holds between semantic rules and necessity claims generates spurious claims of metaphysical necessity, whether the view is circular (implicitly relying on a more 'robust' form of modal realism), and whether it conflicts with truth-conditional semantics. They also raise probing questions about how it compares to other views of modality, including a Lewisian view and an (...) essentialist view. In these replies, I respond to these challenges in ways that precisify the relevant understanding of ‘semantic rules' and the forms they can take, that make clearer the direction of explanation in modal normativism in ways that show the view doesn't rely on a more ‘robust’ form of modal realism, and that give reason for thinking that there is actually no conflict between modal normativism and truth-conditional semantics. I also aim to give a fuller assessment of how it compares to other approaches to modality, including an essentialist approach. (shrink)

A lógica, considerada como uma disciplina técnica iniciada por Aristóteles e tipicamente representada pela variedade de cálculos lógicos modernos, constitui um esclarecimento e refinamento de uma convicção e prática presentes no senso comum, ou seja, o fato de que os seres humanos crêem que a verdade pode ser adquirida não apenas por evidência imediata, mas também por meio de argumentos. Como uma primeira aproximação, a lógica pode ser vista como um registro “descritivo” das principais formas de argumento presentes no senso (...) comum, mas o fato de que alguns desses padrões possam realmente permitir a derivação de consequências falsas a partir de premissas verdadeiras impõe a tarefa de tornar explícitos que padrões correspondem a um “raciocínio correto” e quais não. Nesse ponto, a lógica (que contém a apresentação de tais padrões) parece ser dotada de uma característica “normativa”. Isso equivale a dizer se pretende que os cálculos lógicos espelhem adequadamente a noção intuitiva de “consequência lógica” e que nesse sentido eles não podem ser totalmente arbitrários ou convencionais, mas devem satisfazer certos requisitos básicos tais como as condições de correção e (tanto quanto possível) de completude semântica. Em tal forma eles são “julgados” de acordo com os requisitos fundamentais presentes no nível do senso comum e aparecem como “idealizações” das espécies de raciocínio praticadas no senso comum. Por essa razão também vários tipos de cálculos lógicos são inteiramente justificados uma vez que tornam explícitos, de uma forma idealizada, os modos concretos de raciocinar que são impostos pelo particular domínio de referência da disciplina na qual são usados e que são basicamente reconhecidos no senso comum.

This volume is a selection of Broome's recent papers on normativity, rationality, and reasoning. It covers a variety of topics such as the meanings of 'ought', 'reason', and 'reasons'; the fundamental structure of normativity and the metaphysical priority of ought over reasons; the ownership - or agent-relativity - of oughts and reasons; the distinction between rationality and normativity; the notion of rational motivation; what characterizes the human activity of reasoning, and what is the role of normativity within (...) it; the nature of preferences and of reasoning with preferences; and others. These papers extend the work presented in his book Rationality Through Reasoning but there is little overlap between their content and the book's. They develop further some themes and arguments from the book, and answer some questions that the book left unanswered. (shrink)

Abstract:This paper outlines three conceptions of the relationship between normative and empirical business ethics, views we refer to asparallel, symbiotic, andintegrative. Parallelism rejects efforts to link normative and empirical inquiry, for both conceptual and practical reasons. The symbiotic position supports a practical relationship in which normative and/or empirical business ethics rely on each other for guidance in setting agenda or in applying the results of their conceptually and methodologically distinct inquiries. Theoretical integration countenances a deeper merging ofprima faciedistinct forms (...) of inquiry, involving alterations or combinations of theory, metatheoretical assumptions, and methodology. This paper explicates these positions, summarizes arguments for and against each, and considers their implications for the future of business ethics research. (shrink)

This paper concerns connection between knowing or accepting a logical principle such as Modus Ponens and actions of reasoning involving it. Discussions of this connection typically mention the so-called ‘Lewis Carroll Regress’ and there is near consensus that the regress shows something important about it. Also, although the regress explicitly concerns logic, many philosophers think that it establishes a more general truth, about the structurally similar connection between epistemic or practical principles and actions involving them. This paper’s first aim is (...) to address key interpretations Carroll’s regress as clearly as possible so as to show precisely how it might be relevant to questions concerning the connection between logical knowledge and reasoning, and, more broadly, to discussions of how epistemic or practical principles may be action-guiding. Its second aim is to show that the regress fails to establish anything of substance about the connection between logical knowledge and reasoning, or any other structurally similar relation, unless substantive, contentious and typically undefended assumptions are made. The consensus is thus on shaky ground. (shrink)

It is a popular view thatpractical deliberation excludes foreknowledge of one's choice. Wolfgang Spohn and Isaac Levi have argued that not even a purely probabilistic self-predictionis available to thedeliberator, if one takes subjective probabilities to be conceptually linked to betting rates. It makes no sense to have a betting rate for an option, for one's willingness to bet on the option depends on the net gain from the bet, in combination with the option's antecedent utility, rather than on the offered (...) odds. And even apart from this consideration, assigning probabilities to the options among which one is choosing is futile since such probabilities could be of no possible use in choice. The paper subjects these arguments to critical examination and suggests that, appearances notwithstanding, practical deliberation need not crowd outself-prediction. (shrink)

Practical reasoning is a process of reasoning that concludes in an intention. One example is reasoning from intending an end to intending what you believe is a necessary means: 'I will leave the next buoy to port; in order to do that I must tack; so I'll tack', where the first and third sentences express intentions and the second sentence a belief. This sort of practical reasoning is supported by a valid logical derivation, and therefore seems uncontrovertible. A more contentious (...) example is normative practical reasoning of the form 'I ought to φ, so I'll φ', where 'I ought to φ' expresses a normative belief and 'I'll φ' an intention. This has at least some characteristics of reasoning, but there are also grounds for doubting that it is genuine reasoning. One objection is that it seems inappropriate to derive an intention to φ from a belief that you ought to φ, rather than a belief that you ought to intend to φ. Another is that you may not be able to go through this putative process of reasoning, and this inability might disqualify it from being reasoning. A third objection is that it violates the Humean doctrine that reason alone cannot motivate any action of the will. This paper investigates these objections. (shrink)

David Hume’s “Title Principle,” as it has come to be called, is a specification of the normative scope of reason: “Where reason is lively, and mixes itself with some propensity, it ought to be assented to. Where it does not, it never can have any title to operate on us.” This chapter seeks to answer four central questions about the principle. First, what does Hume mean by “reason” in it? Second, what particular kinds of beliefs does it mandate or disallow? (...) Third, what kind of normativity is expressed by its use of “ought”? Fourth, can it permit Hume properly to overcome—if only to some extent—the “doubts,” “contradictions and imperfections,” and “objections” concerning the use of reason that he describes prior to stating the principle? The chapter concludes with brief reflections on the significance for contemporary epistemology of Hume’s use of the Title Principle. (shrink)

This paper provides moderate criticism of so-called normative theories of thinking and reasoning. The discussion focuses on the problems of idealization, adequacy, inconsistent yet non-trivial logics, logical omniscience etc. I called them “internal” to the normative approach, because they stem from the very properties of formal systems used to model these two human activities. Some arguments, however, refer to the current theories in cognitive science, including those which are developed within “descriptive” framework.

Alan Millar examines our understanding of why people think and act as they do. His key theme is that normative considerations form an indispensable part of the explanatory framework which we use to understand each other. Millar offers illuminating discussions of reasons for belief and reasons for action, the explanation of beliefs and actions in terms of the subject's reasons, the idea that simulation has a key role in understanding people, and the limits of explanation in terms (...) of propositional attitudes.

In recent years, questions about epistemic reasons, norms and goals have seen an upsurge of interest. The present volume brings together eighteen essays by established and upcoming philosophers in the field. The contributions are arranged into four.

Reason aims at truth, so normative considerations are a proper part of the study of reasoning. Excluding them means neglecting some of what we know or can discover about reasoning. Also, the normativist position we are asked to reject by Elqayam & Evans (E&E) is defined in attenuated and self-contradictory ways.

Deontic reasoning is thinking about whether actions are forbidden or allowed, obligatory or not obligatory. It is proposed that social norms, imposing constraints on individual actions, constitute the fundamental concept for the system of these four deontic modalities, and that people reason from such norms flexibly according to deontic core principles. Two experiments are presented, one on deontic conditional reasoning, the other on “pure” deontic reasoning. Both experiments demonstrate people's high deontic competence and confirm the proposed representational and (...) inferential principles. Experiment 1 additionally shows small effects of the conditional formulations. These findings support the dual source approach (Beller & Spada, 2003) that distinguishes between domain-specific and domain-general inferences. Implications for other theories of deontic reasoning are discussed. (shrink)

Reasoning is a process through which premise-attitudes give rise to a conclusion-attitude. When you reason actively you operate on the propositions that are the contents of your premise-attitudes, following a rule, to derive a new proposition that is the content of your conclusion-attitude. It may seem that, when you follow a rule, you must, at least implicitly, have the normative belief that you ought to comply with the rule, which guides you to comply. But I argue that to follow a (...) rule is to manifest a particular sort of disposition, which can be interpreted as an intention. An intention is itself a guiding disposition. It can guide you to comply with a rule, and no normative belief is required. (shrink)

Drawing on a rich pragmatist tradition, this book offers an account of the different kinds of ‘oughts’, or varieties of normativity, that we are subject to contends that there is no conflict between normativity and the world as science describes it. The authors argue that normative claims aim to evaluate, to urge us to do or not do something, and to tell us how a state of affairs ought to be. These claims articulate forms of action-guidance that are different in (...) kind from descriptive claims, with a wholly distinct practical and expressive character. This account suggests that there are no normative facts, and so nothing that needs any troublesome shoehorning into a scientific account of the world. This work explains that nevertheless, normative claims are constrained by the world, and answerable to reason and argumentation, in a way that makes them truth-apt and objective. (shrink)

To have free will with respect to an act is to have the ability both to perform and to refrain from performing it. In this book, Ishtiyaque Haji argues that no one can have practical reasons of a certain sort - "objective reasons" - to perform some act unless one has free will regarding that act.

This book presents an account of normative practical reasons and the way in which they contribute to the rationality of action. Rather than simply 'counting in favour of' actions, normative reasons play two logically distinct roles: requiring action and justifying action. The distinction between these two roles explains why some reasons do not seem relevant to the rational status of an action unless the agent cares about them, while other reasons retain all their force regardless of (...) the agent's attitude. It also explains why the class of rationally permissible action is wide enough to contain not only all morally required action, but also much selfish and immoral action. The book will appeal to a range of readers interested in practical reason in particular, and moral theory more generally. (shrink)

Many have been attracted to the idea that for something to be good there just have to be reasons to favour it. This view has come to be known as the buck-passing account of value. According to this account, for pleasure to be good there need to be reasons for us to desire and pursue it. Likewise for liberty and equality to be values there have to be reasons for us to promote and preserve them. Extensive discussion (...) has focussed on some of the problems that the buck-passing account faces, such as the 'wrong kind of reason' problem. Less attention, however, has been paid as to why we should accept the buck-passing account or what the theoretical pay-offs and other implications of accepting it are. The Normative and the Evaluative provides the first comprehensive motivation and defence of the buck-passing account of value. Richard Rowland argues that the buck-passing account explains several important features of the relationship between reasons and value, as well as the relationship between the different varieties of value, in a way that its competitors do not. He shows that alternatives to the buck-passing account are inconsistent with important views in normative ethics, uninformative, and at odds with the way in which we should see practical and epistemic normativity as related. In addition, he extends the buck-passing account to provide an account of moral properties as well as all other normative and deontic properties and concepts, such as fittingness and ought, in terms of reasons.

The design and analysis of norms is a somewhat neglected topic in AI and Law, but this is not so in other areas of Computer Science. In recent years powerful techniques to model and analyse norms have been developed in the Multi-Agent Systems community, driven both by the practical need to regulate electronic institutions and open agent systems, and by a theoretical interest in mechanism design and normative systems. Agent based techniques often rely heavily on enforcing norms (...) using the software to prevent violation, but I will also discuss the use of sanctions and rewards, and the conditions under which compliance by autonomous agents (including humans) can be expected or encouraged without sanctions or rewards. In the course of the paper a suggested framework for the exploration of these issues is developed. (shrink)

The paper discusses the notion of defeasibility and focuses specifically on defeasible norms. First, it delineates a robust notion of the phenomenon of defeasibility, which poses a serious problem for both moral and legal theory. It does this by laying out the conditions and desiderata that a model of defeasibility should be able to meet. It further focuses on a specific model of defeasibility that utilises the notion of normal conditions to expound the robust notion of defeasibility. It argues (...) that this model fails in its attempt to do this, particularly since it presupposes further pertinent norms and we have reasons to doubt if these are defeasible. It thus does not allow defeasibility to go “all the way down” in the normative domain and limits it merely to a feature of some sort of mid-level norm. In conclusion, it draws lessons from this and positions defeasibility models within a more general pluralistic approach to norms. (shrink)
