We investigate under what conditions contrary-to-duty (CTD) structures lacking temporal and action elements can be given a coherent reading. We argue, contrary to some recent proposals, that CTD is not an instance of defeasible reasoning, and that methods of nonmonotonic logics are inadequate since they are unable to distinguish between defeasibility and violation of primary obligations. We propose a semantic framework based on the idea that primary and CTD obligations are obligations of different kinds: (...) a CTD obligation pertains to, or pre-supposes, a certain context in which a primary obligation is already violated. This framework is presented initially as an extension of Standard Deontic Logic (SDL), a normal modal logic of type KD, and is illustrated by application to a series of examples. The concluding section is concerned with some resemblances between CTD and defeasible reasoning. We show first that the SDL-based framework contains a flaw and must be adjusted. A discussion of possible adjustments, including an alternative treatment in terms of a preference-based semantics, reveals difficulties that are reminiscent of problems in defeasible reasoning and intensional accounts of defeasible conditionals.

This paper discusses the relation between deontic logic and the study of conversational interactions. Special attention is given to the notion of remedial interchange as analysed by sociologists and linguistic pragmaticians. This notion is close to the one of contrary-to-duty (reparational) obligation, which deontic logicians have been studying in its own right. The present article also investigates the question of whether some of the aspects of conversational interactions can fruitfully be described by using formal tools originally developed in (...) the study of iterated belief change. I here adapt the latter tools to deontic logic, and attempt an account of remedial interchange (and, more generally, contrary-to-duty reasoning) in terms of commutation. This account brings the dynamics of obligations to the fore. (shrink)

A contrary-to-duty obligation (sometimes called a reparational duty) is a conditional obligation where the condition is forbidden, e.g. “if you have hurt your friend, you should apologise”, “if he is guilty, he should confess”, and “if she will not keep her promise to you, she ought to call you”. It has proven very difficult to find plausible formalisations of such obligations in most deontic systems. In this paper, we will introduce and explore a set of temporal (...) alethic dyadic deontic systems, i.e., systems that include temporal, alethic and dyadic deontic operators. We will then show how it is possible to use our formal apparatus to symbolise contrary-to-duty obligations and to solve the so-called contrary-to-duty (obligation) paradox, a problem well known in deontic logic. We will argue that this response to the puzzle has many attractive features. Semantic tableaux are used to characterise our systems proof theoretically and a kind of possible world semantics, inspired by the so-called T× W semantics, to characterise them semantically. Our models contain several different accessibility relations and a preference relation between possible worlds, which are used in the definitions of the truth conditions for the various operators. Soundness results are obtained for every tableau system and completeness results for a subclass of them. (shrink)

I argue that normative requirements should be interpreted as the conditional obligations of dyadic deontic logic. Semantically, normative requirements are conditionals understood as restrictors, the prevailing view of conditionals in linguistics. This means that Modus Ponens is invalid, even when the premises are known.

A contrary-to-duty obligation (CTD obligation) is a type of conditional obligation that tells us what to do when a primary duty is violated. Chisholm’s Paradox is one of the most famous deontic puzzles about CTD obligations. It is widely believed that Chisholm’s Paradox does not arise for ordering semantics, today’s orthodox semantics for modals and conditionals. In this paper, I propose a new puzzle, the CTD Trilemma, to show that ordering semantics still has difficulties in adequately (...) representing natural reasoning with CTD obligations. I argue that to solve the CTD Trilemma a formal account must attend to two different functions played by ought-statements in our normative reasoning and discourse: ought-statements as normative rules and normative judgments. To formally capture this distinction I develop a new dynamic account of ought-statements and normative reasoning inspired by Frank Veltman’s update semantics for default reasoning. Finally, I show how my update semantics for normative reasoning provides a simple and elegant solution to the CTD Trilemma and explains seemingly inconsistent data about inferences using ought-statements in normative reasoning.

In this paper we present a Gentzen system for reasoning with contrary-to-duty obligations. The intuition behind the system is that a contrary-to-duty is a special kind of normative exception. The logical machinery to formalise this idea is taken from substructural logics and it is based on the definition of a new non-classical connective capturing the notion of reparational obligation. Then the system is tested against well-known contrary-to-duty paradoxes.

We show that Carmo and Jones’ condition 5 conflicts with the other conditions on their models for contrary-to-duty obligations. We then propose a resolution to the conflict.

A contrary-to-duty obligation is an obligation that tells us what ought to be the case if something that is wrong or forbidden is true. Alternatively, we might say that a contrary-to-duty obligation is a conditional obligation where the condition is fulfilled only if a primary obligation is violated. Consider this example: “If you have hurt her feelings, you should make amends.” Since contrary-to-duty obligations play an important role in our moral and legal thinking, (...) we want to find a good analysis of this concept. However, it has turned out to be difficult to formalize various contrary-to-duty obligations. This is illustrated by the so-called contrary-to-duty paradox. This paradox is generated when we try to symbolize various scenarios that include at least one contrary-to-duty obligation in many formal deontic systems, such as Standard Deontic Logic. Such symbolizations are often inconsistent or entail some other problematic consequences. This entry is a brief introduction to this problem. (shrink)

This paper provides an analysis of contrary-to-duty reasoning from the proof-theoretical perspective of category theory. While Chisholm’s paradox hints at the need of dyadic deontic logic by showing that monadic deontic logics are not able to adequately model conditional obligations and contrary-to-duties, other arguments can be objected to dyadic approaches in favor of non-monotonic foundations. We show that all these objections can be answered at one fell swoop by modeling conditional obligations within a deductive system (...) defined as an instance of a symmetric monoidal closed category. Using category theory as a foundational framework for logic, we show that it is possible to model conditional normative reasoning and conflicting obligations within a monadic approach without adding further operators or considering deontic conditionals as primitive. (shrink)

In this paper, I will discuss some examples of the so-called contrary-to-duty paradox, a well-known puzzle in deontic logic. A contrary-to-duty obligation is an obligation telling us what ought to be the case if something forbidden is true, for example: ‘If she is guilty, she should confess’. Contrary-to-duty obligations are important in our moral and legal thinking. Therefore, we want to be able to find an adequate symbolisation of such obligations in some (...) logical system, a task that has turned out to be difficult. This is shown by the so-called contrary-to-duty paradox. I will investigate and evaluate one kind of solution to this problem that has been suggested in the literature, which I will call the ‘counterfactual solution’. I will use some recent systems that combine not only counterfactual logic and deontic logic, but also temporal logic, in my analysis of the paradox. I will argue that the counterfactual solution has many attractive features and that it can give a fairly satisfactory answer to some examples of the contrary-to-duty paradox, but that it nevertheless has some serious problems. The conclusion is that, notwithstanding the many attractive features of the solution, there seem to be other approaches to the paradox that are more promising. (shrink)

This paper provides a new framework for formalizing conditional obligations in natural language: it pairs a unary deontic operator with trivalent semantics for the indicative conditional and Kratzer's idea that the antecedents of conditionals restrict the scope of modals in the consequent. Combining these three ideas, we obtain a fully compositional theory of "if" and "ought'" that validates plausible principles for deontic reasoning. Moreover, it resolves classical challenges such as the "if A then ought A" problem, the paradox of (...) the miners and the modeling of contrary-to-duty obligations (e.g., Chisholm's quartet). All in all, our proposal is attractive from a logical point of view and squares well with general theories of natural language reasoning. (shrink)

In a previous paper we developed a general theory of input/output logics. These are operations resembling inference, but where inputs need not be included among outputs, and outputs need not be reusable as inputs. In the present paper we study what happens when they are constrained to render output consistent with input. This is of interest for deontic logic, where it provides a manner of handling contrary-to-duty obligations. Our procedure is to constrain the set of generators of (...) the input/output system, considering only the maximal subsets that do not yield output conflicting with a given input. When inputs are authorised to reappear as outputs, both maxichoice revision in the sense of Alchourr6n/Makinson and the default logic of Poole emerge as special cases, and there is a close relation with Reiter default logic. However, our focus is on the general case where inputs need not be outputs. We show in what contexts the consistency of input with output may be reduced to its consistency with a truth-functional combination of components of generators, and under what conditions constrained output may be obtained by a derivation that is constrained at every step.

This paper presents a justification counterpart for dyadic deontic logic, which is often argued to be better than Standard Deontic Logic at representing conditional and contrary-to-duty obligations, such as those exemplified by the notorious Chisholm’s puzzle. We consider the alethic-deontic system (E) and present the explicit version of this system (JE) by replacing the alethic Box-modality with proof terms and the dyadic deontic Circ-modality with justification terms. The explicit representation of strong factual detachment (SFD) is given and (...) finally soundness and completeness of the system (JE) with respect to basic models and preference models is established.

I present a novel account of unconditional obligation and of its relationship to conditional obligation and bring this account to bear upon Chisholm's puzzle concerning contrary-to duty obligation.

Formalising deontic concepts, such as obligation, prohibition and permission, is normally carried out in a modal logic with a possible world semantics, in which some worlds are better than others. The main focus in these logics is on inferring logical consequences, for example inferring that the obligation O q is a logical consequence of the obligations O p and O. In this paper we propose a non-modal approach in which obligations are preferred ways of satisfying goals expressed in (...) first-order logic. To say that p is obligatory, but may be violated, resulting in a less than ideal situation s, means that the task is to satisfy the goal p ∨ s, and that models in which p is true are preferred to models in which s is true. Whereas, in modal logic, the preference relation between possible worlds is part of the semantics of the logic, in this non-modal approach, the preference relation between first-order models is external to the logic. Although our main focus is on satisfying goals, we also formulate a notion of logical consequence, which is comparable to the notion of logical consequence in modal deontic logic. In this formalisation, an obligation O p is a logical consequence of goals G, when p is true in all best models of G. We show how this non-modal approach to the treatment of deontic concepts deals with problems of contrary-to-duty obligations and normative conflicts, and argue that the approach is useful for many other applications, including abductive explanations, defeasible reasoning, combinatorial optimisation, and reactive systems of the production system variety.

This article proposes a systematic application of recent developments in the logic of preference to a number of topics in deontic logic. The key junction is the well‐known Hansson conditional for dyadic obligations. These conditionals are generalized by pairing them with reasoning about syntactic priority structures. The resulting two‐level approach to obligations is tested first against standard scenarios of contrary‐to‐duty obligations, leading also to a generalization for the Kanger‐Anderson reduction of deontic logic. Next, the priority (...) framework is applied to model two intuitively different sorts of deontic dynamics of obligations, based on information changes and on genuine normative events. In this two‐level setting, we also offer novel takes on vexed issues such as the Chisholm paradox and modelling strong permission. Finally, the priority framework is shown to provide a unifying setting for the study of operations on norms as such, in particular, adding or deleting individual norms, and even merging whole norm systems in different manners.

This paper examines the deontic logic of the Talmud. We shall find, by looking at examples, that at first approximation we need deontic logic with several connectives: O T A Talmudic obligation F T A Talmudic prohibition F D A Standard deontic prohibition O D A Standard deontic obligation. In classical logic one would have expected that deontic obligation O D is definable by $O_DA \equiv F_D\neg A$ and that O T and F T are connected by $O_TA \equiv F_T\neg (...) A$ This is not the case in the Talmud for the T (Talmudic) operators, though it does hold for the D operators. We must change our underlying logic. We have to regard {O T , F T } and {O D , F D } as two sets of operators, where O T and F T are independent of one another and where we have some connections between the two sets. We shall list the types of obligation patterns appearing in the Talmud and develop an intuitionistic deontic logic to accommodate them. We shall compare Talmudic deontic logic with modern deontic logic. (shrink)

Since it was presented in 1963, Chisholm’s paradox has attracted constant attention in the deontic logic literature, but without the emergence of any definitive solution. We claim this is due to its having no single solution. The paradox actually presents many challenges to the formalization of deontic statements, including (1) context sensitivity of unconditional oughts, (2) formalizing conditional oughts, and (3) distinguishing generic from nongeneric oughts. Using the practical interpretation of ‘ought’ as a guideline, we propose a linguistically motivated logical (...) solution to each of these problems, and explain the relation of the solution to the problem of contrary-to-duty obligations.

Conditionals that contain a modality in the consequent give rise to a particular semantic phenomenon whereby the antecedent of the conditional blocks possibilities when interpreting the modality in the consequent. This explains the puzzling logical behaviour of constructions like "If you don't buy a lottery ticket, you can't win", "If you eat that poison, it is unlikely that you will survive the day" and "If you kill Harry, you ought to kill him gently". In this paper it is argued that (...) a semantic version of the Ramsey Test provides a key in the analysis of such constructions. The logic for this semantics is axiomatized and some examples are studied, among them a well-known puzzle for contrary-to-duty obligations. (shrink)

We introduce -ranked preferential structures and combine them with an accessibility relation. -ranked preferential structures are intermediate between simple preferential structures and ranked structures. The additional accessibility relation allows us to consider only parts of the overall -ranked structure. This framework allows us to formalize contrary to duty obligations, and other pictures where we have a hierarchy of situations, and maybe not all are accessible to all possible worlds. Representation results are proved.

The aim of this paper is to strengthen the point made by Horty about the relationship between reason holism and moral particularism. In the literature prima facie obligations have been considered as the only source of reason holism. I strengthen Horty’s point in two ways. First, I show that contrary-to-duties provide another independent support for reason holism. Next I outline a formal theory that is able to capture these two sources of holism. While in simple settings the proposed (...) account coincides with Horty’s one, this is not true in more complicated or “realistic” settings in which more than two norms collide. My chosen formalism is so-called input/output logic. A bottom-line example is introduced. It raises the issue of whether the conventional wisdom is right in assuming that normative reasons run parallel to epistemic ones. (shrink)

We present a formal argumentation system for dealing with the detachment of prioritized conditional obligations and permissions. In the presence of facts and constraints, we answer the question whether an unconditional obligation or permission is detachable by considering arguments for and against its detachment. For the evaluation of arguments in favour of detachment, we use a Dung-style argumentation-theoretical semantics. We illustrate how violations and contrary-to-duty scenarios are dealt with in our framework and pay special attention to conflict-resolution (...) via priorities. (shrink)

In some cases, you may release someone from some obligation they have to you. For instance, you may release them from a promise they made to you, or an obligation to repay money they have borrowed from you. But most take it as clear that, if you have an obligation to someone else, you cannot in any way release yourself from that obligation. I shall argue the contrary. The issue is important because one standard problem for the idea of (...) having duties to oneself relies on the impossibility of self-release. The argument is that a duty to oneself would be a duty from which one could release oneself, but that this is an absurdity, and so there can be no duties to oneself. This argument is to be rejected because a duty from which one can release oneself is perfectly possible, and such release occurs quite properly from time to time. (shrink)

Butler observes in the Preface to the Sermons that the subject of morals can be approached in two different ways: “One begins from enquiring into the abstract relations of things: the other from a matter of fact, namely what the particular nature of man is, its several parts, their economy or constitution; from whence it proceeds to determine what course of life it is, which is correspondent to his whole nature. In the former method the conclusion is expressed thus, that (...) vice is contrary to the nature and reason of things: in the latter, that it is a violation or breaking in upon our own nature. Thus they both lead us to the same thing, our obligations to the practice of virtue; and thus they exceedingly strengthen and enforce each other.” In making this observation Butler raises the problem of the nature of moral obligation, and of the criteria by which the existence of a moral obligation can be known. He does so by calling attention to the divisions of opinion which existed on this issue in his own days. Samuel Clarke, the fashionable moralist of the period, sought the roots of moral obligation in the “nature and reason of things”: for an agent to know that an act is his duty is to know that it is fitting or suitable to the circumstances in which it occurs . Shaftesbury, on the other hand, and many of the adherents to the doctrine of Natural Law, like Grotius and Pufendorf, sought the roots of moral obligation in the nature of agents: for an agent, to know that an act is his duty is for him to experience a special motive to do it . Butler recognized the fundamental difference between these two approaches. (shrink)

Professionals have a role obligation to satisfy certain standards when performing their work. However, as professionals, can they perform morally praiseworthy acts that are not within the scope of duty? According to applied professional ethics, the answer is yes, whereas some theoretical accounts of supererogation deny this possibility. I examine and ultimately reject two very different theoretical accounts that deny professional supererogation. First, a recent interpretation of Aristotle uses examples from the professional context to illustrate that the moral category (...) of supererogation is not needed to describe heroic acts. Second, David Heyd’s account of supererogation argues that the category applies to natural duties alone and not to professional as professionals. Contrary to these claims, I argue that it is not only conceptually coherent to allow for the possibility of going beyond the call of duty but also morally important for assessments of responsibility and blame in professional life.

Actualists hold that contrary-to-duty scenarios give rise to deontic dilemmas and provide counterexamples to the transmission principle, according to which we ought to take the necessary means to actions we ought to perform. In an earlier article, I have argued, contrary to actualism, that the notion of ‘ought’ that figures in conclusions of practical deliberation does not allow for deontic dilemmas and validates the transmission principle. Here I defend these claims, together with my possibilist account of (...) class='Hi'>contrary-to-duty scenarios, against Stephen White’s recent criticism. (shrink)

Gyekye argues for the moral supremacy of certain duties. The individual is, as a natural member of the cultural community, morally obligated to respect community values; co-operate with fellow community members, be sensitive to the economic plight of others and morally expected to respect the elderly. Though Gyekye recognizes the moral need to respect certain individual rights, in the case of a moral clash between those rights and the values cherished by the community, the latter must be upheld. I wish (...) to critically examine the arguments in support of this position. Contrary to Gyekye's view, I argue that the natural interpersonal bond among members of the same cultural community does not strongly support some of the duties mentioned. However, I am not arguing that the individual person is not morally obligated to the cultural community at all. I argue that natural membership of the cultural community could be a necessary condition for the justification of certain duties; it is not, morally, a sufficient condition. (shrink)

ABSTRACT This paper [1] is a defence of a modified version of Jane English's model of filial obligations based on adult children's friendship with their parents. Unlike the more traditional view that filial obligations are a repayment for parental sacrifices, the friendship model puts filial duties in the appealing context of voluntary, loving relationships. Contrary to English's original statement of this view, which is open to the charge of tolerating filial ingratitude, the friendship model can generate (...) class='Hi'>obligations to help our parents even if we are no longer friendly with them. Joseph Kupfer has pointed out several ways in which parent‐child relationships differ from peer friendships; but his arguments do not preclude our enjoying a type of friendship with our parents. In response to Christina Hoff Sommers, who objects that feelings of friendship toward our parents are too flimsy a ground for filial duties, the friendship model can provide a plausible, robust account of filial obligations. As for adult children who have never formed friendships with their loving, caring parents, and refuse to give them much‐needed assistance, they can be criticised by moral considerations independent of but compatible with the friendship model.

In this paper we propose an extension of Defeasible Logic to represent and compute different concepts of defeasible permission. In particular, we discuss some types of explicit permissive norms that work as exceptions to opposite obligations or encode permissive rights. Moreover, we show how strong permissions can be represented both with, and without introducing a new consequence relation for inferring conclusions from explicit permissive norms. Finally, we illustrate how a preference operator applicable to contrary-to-duty obligations can (...) be combined with a new operator representing ordered sequences of strong permissions. The logical system is studied from a computational standpoint and is shown to have linear computational complexity. (shrink)

Leading American film critics, including, among others, Tony Williams and Robert Miklitsch, have claimed that both World for Ransom and Macao reflect an orientalist, racist, and reactionary worldview. In this article I argue that, on the contrary, these 1950s films noir portray Asian and American characters alike actually carrying out their moral duties. To be sure, these American films employ aesthetic techniques to help illustrate the ethical ambiguities for which film noir is justly celebrated. Still, where the fulfillment of (...) moral duties is concerned, the films’ resolutions are clear. This article enlists the thought of moral philosophers H.L.A. Hart and Daniel Statman to vindicate the ethical outlook of these works, which reward characters who fulfill imperfect, perfect, and/or supererogatory moral obligations. The American protagonists transcend their given circumstances by carrying out high-stake duties in an Asian setting, while forming amorous alliances tested by the aesthetics of film noir. Moreover, I show that none of the protagonists’ moral duties involves maligning Asia. Indeed, were these films noir to disparage Asia, they would diminish the very milieu breathing life into their finest characters. (shrink)

Despite growing evidence to the contrary, researchers continue to posit causal links between cannabis, crime, psychosis, and violence. These spurious connections are rooted in history and fueled decades of structural limitations that shaped how researchers studied cannabis. Until recently, research in this area was explicitly funded to link cannabis use and harm and ignore any potential benefits. Post-prohibition cannabis research has failed to replicate the dire findings of the past. This article outlines how the history of controlling cannabis research (...) has led to various harms, injustices, and ethical complications. We compare commonly cited research from both the prohibition and post-prohibition eras and argue that many popular claims about the dangers of cannabis are the result of ethical lapses by researchers, journals, and funders. We propose researchers in this area adopt a duty of care in cannabis research going forward. This would oblige individual researchers to establish robust research designs, employ careful analytic strategies, and acknowledge limitations in more detail. This duty involves the institutional recognition by funders, journals, and others that cannabis research has been deliberately misconstrued to criminalize, stigmatize, and pathologize. (shrink)

In Meyer’s promising account [7] deontic logic is reduced to a dynamic logic. Meyer claims that with his account “we get rid of most (if not all) of the nasty paradoxes that have plagued traditional deontic logic.” But as was shown by van der Meyden in [4], Meyer’s logic also contains a paradoxical formula. In this paper we will show that another paradox can be proven, one which also effects Meyer’s “solution” to contrary to duty obligations and (...) his logic in general. (shrink)

New testamentThe British Medical Association recently published guidance from its medical ethics committee on decision making concerning the withholding and withdrawing of life-prolonging medical treatment.1 It is a very thoughtful and thought-provoking document, the ramifications of which go far beyond the immediate situation it is addressing. The authors are clearly well aware of this. When considering a doctor's ethical response to “contemporaneous requests for life-prolonging treatment” made by competent patients, the committee observes:“Although patients' wishes should always be discussed with them, (...) the fact that a patient has requested a particular treatment does not mean that it must always be provided.”2They advance four propositions in support of this conclusion, namely: Health professionals are not obliged to provide any treatment which cannot produce the desired benefit”.3 There is no obligation to provide any treatment which is clearly contrary to an individual's health interests. A life-prolonging treatment may, for example, prolong life but result in severe pain or loss of function so that overall it produces severe harm to the patient”.4 Except in an emergency situation, doctors are not obliged to treat contrary to their conscience ”.4 Where resources are limited, it is inevitable that some patients will not receive all of the treatment they request even though such treatment could be potentially beneficial to them”.4Towards the end of their commentary on the last of these propositions, they observe:“Health professionals have an ethical duty to make the best use of the available resources and this means that hard decisions must be made. Whilst this is a much broader issue than can be discussed thoroughly in this document, it is clear that doctors are not obliged to comply with patients' requests for treatment when they …. (shrink)

To consequentialize a deontological moral theory is to give a theory which issues the same moral verdicts, but explains those verdicts in terms of maximizing or satisficing value. There are many motivations for consequentializing: to reconcile plausible ideas behind deontology with plausible ideas behind consequentialism, to help us better understand deontological theories, or to extend deontological theories beyond what intuitions alone tell us. It has proven difficult to consequentialize theories that allow for moral dilemmas or that deny that “ought” implies (...) “can.” This article argues that the problem is best solved by allowing impossible actions as inputs into consequentializations. It shows that all other approaches that have been advocated are inadequate. It also argues that progress in consequentialization, and in formal ethics more generally, requires thinking about more than just wrongness and permissibility; we should think about contrary-to-duty obligations and degrees of wrongness as well.

Recent debate in the literature on political obligation about the principle of fairness rests on a mistake. Despite the widespread assumption to the contrary, a person can have a duty of fairness to share in the burdens of sustaining some cooperative scheme even though that scheme does not represent a net benefit to her. Recognizing this mistake allows for a resolution of the stalemate between those who argue that the mere receipt of some public good from a scheme (...) can generate a duty of fairness and those who argue that only some voluntary action of consent or acceptance of the good can generate such a duty. I defend a version of the principle of fairness that holds that it is the person’s reliance on a scheme for the provision of some product or service that generates duties of fairness to share in the burdens of sustaining the scheme. And, on this version, the principle of fairness is politically significant: regardless of whether the citizen has a duty to obey the law, she will still have important political duties of fairness generated by her reliance on the various public goods provided by those society-wide cooperative schemes sustained by the sacrifices of her fellow citizens.

Formal arguments are often represented by pairs, but in this paper we consider normative arguments represented by sequences of triples, where constitutive norms derive institutional facts from brute facts, and regulative norms derive deontic facts like obligations and permissions from institutional facts. The institutional facts may be seen as the reasons explaining or warranting the deontic obligations and permissions, and therefore they can be attacked by other normative arguments too. We represent different aspects of normative reasoning by different (...) kinds of consistency checks among these triples, and we use formal argumentation theory to resolve conflicts among such normative arguments. In particular, we introduce various requirements for arguing about norms concerning violations, contrary-to-duty obligations, dilemmas, conflict resolution and different kinds of norms, and we introduce a formal argumentation theory satisfying the requirements. In order to illustrate our framework, we introduce a running example based on university regulations for prospective and actual students. (shrink)

My three projects here explore some semantic and metaethical problems that are unique to normative language and our normative reasoning. Ch.1 argues that the notion of a contrary-to-duty obligation and its role in normative discourse and reasoning are not adequately captured in the standard semantics for ought-statements, developed by Angelika Kratzer and David Lewis. I show this by presenting a new puzzle, the CTD Trilemma, using a famous example from Chisholm’s Paradox. I claim that two different roles played (...) by ought-statements in normative discourse and reasoning have to be captured in any satisfactory semantic account for normative language. I draw the distinction between axiological and deontological ought-statements in my version of deontic update semantics and how this distinction nicely solves the puzzles about CTD obligations. Ch.2 discusses the challenge that the possibility of moral dilemmas poses to the ordering semantic account of ought-statements. I critically discuss and compare the advantages and disadvantages of two ordering semantic analyses of ought-statements when it comes to moral dilemmas: the conflict and disjunctive accounts. I conclude that in order to adequately describe one’s normative predicament and reasoning in a dilemma situation, two kinds of ought-statements defined by the two accounts have to be captured in a single semantic framework. And, I show how it can be done in the ordering semantic framework. Ch.3 critically evaluates the real force of the Disagreement-Based Argument in metaethics, exemplified by R.M. Hare’s cannibals argument and Horgan and Timmons’ Moral Twin Earth argument. I analyze the structure of the DBA and defuse its direct threat to descriptivism by disproving its most problematic assumption : that genuine disagreement between two parties requires that the parties agree in what they mean by the key terms in the dispute. I argue that the disagreement data the DBA elicits from thought experiments does not put real pressure on descriptivism, because the proponents of descriptivism can explain the data away by showing how two different linguistic communities can genuinely disagree about what to do and how to live.

The most important problem is philosophical deontic logic is to determine the logical form of expressions of conditional obligation. The dissertation shows first that this problem is closely related to David Lewis's well-known "problem about permission"--a problem concerning the characterization of changes in normative systems. The dissertation contains a solution to the problem about permission, as well as an argument that expressions of conditional obligation cannot be represented satisfactorily by means of some combination of monadic deontic operators and a counterfactual (...) conditional . ;Lewis formulates the problem about permission in terms of a language game for imperative and permission sentences. In order to solve the problem it is necessary first to point out the shortcoming in Lewis's game that it cannot be used satisfactorily to provide semantics for "contrary to duty" imperatives. Having revised the game it is possible to define the concept of relative defeasibility between imperatives. It is in terms of this concept that a solution to the problem about permission is formulated. ;The "revised game" is used as well to discuss problems concerning reasoning from sets of rules, principles, and facts to "all things considered" conclusions. It is argued that two distinct senses or uses of 'ought' must be distinguished in order to represent such reasoning satisfactorily. The role of the notion ceteris paribus is discussed. The notion is given a precise definition in terms of the possible worlds semantics of the "revised game" and it is argued that the notion is not as significant in normative reasoning as commonly is supposed. An alternative notion is defined and defended. (shrink)

This chapter develops a novel Neo-Moorean view. The view falls squarely within the Radical Neo-Moorean camp, in that it holds that closure holds unrestrictedly, warrant transmits through Moore’s inference, and that there is nothing wrong – epistemically or dialectically – with Moore’s argument. Nevertheless, the account is superior to extant Radical Neo-Mooreanisms in explanatory power: it explains both the precise variety of epistemic failure exhibited by the sceptic, and the intuition of reasonableness when it comes to the sceptic’s resistance to (...) Moore’s argument. It does so in terms of epistemic functions and contrary-to-duty obligations. (shrink)

ABSTRACT:The oft-cited privacy paradox is the perceived disconnect between individuals’ stated privacy expectations, as captured in surveys, and consumer market behavior in going online: individuals purport to value privacy yet still disclose information to firms. The goal of this paper is to empirically examine the conceptualization of privacy postdisclosure assumed in the privacy paradox. Contrary to the privacy paradox, the results here suggest consumers retain strong privacy expectations even after disclosing information. Privacy violations are valued akin to security violations (...) in creating distrust in firms and in consumer willingness to engage with firms. This paper broadens the scope of corporate responsibility to suggest firms have a positive obligation to identify reasonable expectations of privacy of consumers. In addition, research perpetuating the privacy paradox, through the mistaken framing of disclosure as proof of anti-privacy behavior, gives license to firms to act contrary to the interests of consumers.

Despite all the attention given to Kant’s universalizability tests, one crucial aspect of Kant’s thought is often overlooked. Attention to this issue, I will argue, helps us resolve two serious problems for Kant’s ethics. Put briefly, the first problem is this: Kant, despite his stated intent to the contrary, doesn’t seem to use universalization in arguing for duties to oneself, and, anyway, it is not at all clear why duties to oneself should be grounded on a procedure that envisions (...) a world in which everyone wills the contrary of those duties. The second, more global problem is that if we follow Barbara Herman in holding that Kantian ethics can provide a structure for moral deliberation, we need an interpretation of the universalization procedure that unproblematically allows it to generate something like prima facie duties to guide that deliberation; but it is not at all clear that we have such an interpretation. I argue here that if we expand our limited way of thinking about universalization, we can solve the first problem and work towards a solution to the second. We can begin by recalling that Kant’s ‘Law of Nature’ formulation (FLN) of the Categorical Imperative obligates us to ‘act as if the maxim of your action were to become by your will a universal law of nature’ (G, 421).

Contrary to the recent argument developed by Matthew Kramer, edificatory perfectionism is an integral part of the purpose of the state and as such is required by justice. This claim can be supported by an appropriate understanding of the common good and the principle of subsidiarity. The purpose of the state rests in its duty to secure for its citizens the common good, which is a set of conditions under which all individuals and associations can attain for themselves (...) various reasonable goods or cooperate together to attain them. This includes perfectionist goods, such as living in a favourable moral environment. The relationship between the common good and justice is clarified by the application of the principle of subsidiarity. Its negative formulation is well known as a principle limiting the government’s competence. I draw attention to the positive formulation, which mandates that the state is obliged to assist when individuals and communities cannot achieve their reasonable goals, including perfectionist ones, by themselves. This obligation, though enabling perfectionist actions, is still limited by prudential considerations and plurality of intrinsic goods which requires respect for personal freedom. (shrink)
