How are we to understand the intentionality of desire? According to the two classical views, desire is either a positive evaluation or a disposition to act. This essay examines these conceptions of desire and argues for a deontic alternative, namely the view that desiring is representing a state of affairs as what ought to be. Three lines of criticism of the classical pictures of desire are provided. The first concerns desire’s direction of fit, i.e. the intuition that the (...) world should conform to our desires. The second concerns the “death of desire” principle, i.e. the intuition that one cannot desire what one represents as actual. The last pertains to desire’s role in psychological explanations, i.e. the intuition that desires can explain motivations and be explained by evaluations. Following these criticisms, three positive arguments in favor of the deontic conception are sketched. (shrink)

Desires matter. How are we to understand the intentionality of desire? According to the two classical views, desire is either a positive evaluation or a disposition to act: to desire a state is to positively evaluate it or to be disposed to act to realize it. This Ph.D. Dissertation examines these conceptions of desire and proposes a deontic alternative inspired by Meinong. On this view, desiring is representing a state of affairs as what ought to be or, if (...) one prefers, as what should be. Desire involves a deontic manner of representing: a norm of the ought-to-be type features in desire’s intentional mode, as opposed to content. The dissertation is structured in three parts. In order to defend this conception, I formulate three main desiderata for a promising theory of the intentionality of desire in the introduction (§0). The first concerns desire’s direction of fit, i.e. the intuition that the world should conform to our desires. The second concerns the death of desire principle, i.e. the intuition that one cannot desire what one represents as actual. The last pertains to desire’s role in psychological explanations, i.e. the intuition that desires can explain some mental states and be explained by other mental states. The first part examines the main conceptions of desire in light of these desiderata. I argue that the classical pictures of desire do not adequately meet our desiderata. The first chapter is devoted to the evaluative conception (§1), while the second examines the motivational approach (§2). Following these criticisms, I then present the deontic view of desire (§3). In the second part, I defend this conception with the help of three arguments. The main idea is that appealing to norms of the ought-to-be type can satisfy our chief desiderata: the world should conform to norms (world-to-mind direction of fit, §4), norms are grounded on values and in turn ground obligations (explanation, §5), and norms are about non-actual states of affairs (death of desire principle, §6). In the last part, I develop the deontic view to draw a cartography of the various types of desire. Some desires are correct, while others are inappropriate. This distinction is explained by the deontic conception, as it matches that between states of affairs that ought to obtain and states that should not obtain (§7). Two study cases are examined: caprice and the impermissibility of desire aggregation. Intuitively, hopes, wishes, or urges are types of desire. The next chapter presents a typology inspired by the deontic view and the type of norms there are (§8). The last chapter discusses the main objections to the deontic approach (§9). In conclusion, I show the relevance of the deontic view for several debates in philosophy of mind and ethics. Desires are crucial because they are the ‘eye’ of what should be. (shrink)

This article contains an overview of the author's long‐standing involvement with deontic logic, both from a technical and from a wider philosophical point of view. As far as the formal aspects of deontic logic are concerned, the author describes his intellectual development from the original discovery of the analogy between modal (and deontic) notions on the one hand, and quantifiers on the other, through the formulation of a systematic theory of dyadic deontic concepts, to the (...) proposal of a formal logic of action as a foundation for deontic logic. In a more philosophical vein, the author discusses such questions as the very possibility of deontic logic if norms have no truth‐value, the relation between the descriptive interpretation of classical deontic logic and the logic of norm‐propositions, the correct representation of conditional or hypothetical norms, the distinction between moral obligation and practical necessity, and the interdefinability of permission and obligation.

A suggestion is made for representing iterated deontic modalities in stit theory, the “seeing-to-it-that” theory of agency. The formalization is such that normative sentences are represented as agentive sentences and therefore have history dependent truth conditions. In contrast to investigations in alethic modal logic, in the construction of systems of deontic logic little attention has been paid to the iteration... of the deontic modalities.

An extraordinary amount of recent work by philosophers of language, meta-ethicists, and semanticists has focused on the meaning and function of language expressing concepts having to do with what is allowed, forbidden, required, or obligatory, in view of the requirements of morality, the law, one's preferences or goals, or what an authority has commanded: in short, deontic modality. This volume presents new work on the much-discussed topic of deontic modality by leading figures in the philosophy of language, (...) meta-ethics, and linguistic semantics. The papers tackle issues about the place of decision and probability theory in the semantics of deontic modality, the viability of standard possible worlds treatments of the truth conditions of deontic modal sentences, the possibility of dynamic semantic treatments of deontic modality, the methodology of semantics for deontic modals, and the prospects for representationalist, expressivist, and inferentialist treatments of deontic modality.

Consequentialist views have traditionally taken a maximizing form, requiring agents to bring about the very best outcome that they can. But this maximizing function may be questioned. Satisficing views instead allow agents to bring about any outcome that exceeds a satisfactory threshold or qualifies as “good enough.” Scalar consequentialism, by contrast, eschews moral requirements altogether, instead evaluating acts in purely comparative terms, i.e., as better or worse than their alternatives. After surveying the main considerations for and against each of these (...) three views, I argue that the core insights of each are not (despite appearances) in conflict. Consequentialists should be deontic pluralists and accept a maximizing account of the ought of most reason, a satisficing account of obligation, and a scalar account of the weight of reasons.

John Horty effectively develops deontic logic (the logic of ethical concepts like obligation and permission) against the background of a formal theory of agency. He incorporates certain elements of decision theory to set out a new deontic account of what agents ought to do under various conditions over extended periods of time. Offering a conceptual rather than technical emphasis, Horty's framework allows a number of recent issues from moral theory to be set out clearly and discussed from a (...) uniform point of view.

This book addresses a dilemma concerning freedom and moral obligation (obligation, right and wrong). If determinism is true, then no one has control over one's actions. If indeterminism is true, then no one has control over their actions. But it is morally obligatory, right or wrong for one to perform some action only if one has control over it. Hence, no one ever performs an action that is morally obligatory, right or wrong. The author defends the view that this (...) dilemma can be evaded but not in a way traditional compatibilists about freedom and moral responsibility will find congenial. For moral obligation is indeed incompatible with determinism but not with indeterminism. He concludes with an argument to the effect that, if determinism is true and no action is morally obligatory, right or wrong, then our world would be considerably morally impoverished as several sorts of moral appraisal would be unjustified.

Contrastivists view ought-sentences as expressing comparisons among alternatives. Deontic actualists believe that the value of each alternative in such a comparison is determined by what would actually happen if that alternative were to be the case. One of the arguments that motivates actualism is a challenge to the principle of agglomeration over conjunction—the principle according to which if you ought to run and you ought to jump, then you ought to run and jump. I argue that there is (...) no way of developing the actualist insight into a logic that invalidates the agglomeration principle without also invalidating other desirable patterns of inference. After doing this, I extend the analysis to other contrastive views that challenge agglomeration in the way that the actualist does. This motivates skepticism about the actualist’s way of challenging agglomeration. (shrink)

Expertise is commonly viewed as a professionalized competence in a specific field. Expert professional identities are produced and reproduced through professional training and other socialization mechanisms, which work to generate for a specific group of individuals a specific set of expert skills and knowledge. In this paper, I examine participants’ orientations to their distinct expert professional identities from the perspective of deontic authority. Drawing on 15 video-recorded church workplace meetings between pastors and cantors as data, and conversation analysis as (...) a theoretical and methodological framework, I analyze situations where a non-expert participant makes a proposal that the expert participant orients to as reasonable to comply with. Specifically, I demonstrate how the expert participants respond to these proposals with displays of deontic authority, arguably in an attempt to maintain their expert identities in the face of their de facto compliance with the proposals. In these situations, the expert participants are shown to invoke a past decision of their own, a future decision of their own, or a pattern that is beyond both participants’ control. Each of these practices involves the expert participant balancing resistance and compliance by minimally acknowledging the content of the non-expert participant’s proposal, while excluding the non-expert from those who have deontic authority in the matter. In so doing, the expert speaker implies that the non-expert proposal speaker lacks procedural knowledge about the specific matters about which it is relevant to make proposals to experts and access to the distinct experiential perspective that characterizes expert perception of things. It is thus argued that, in this context, the mere claims of deontic authority, produced without any substantial displays of expert knowledge, can serve the maintenance of expert professional identities.

A range of extremely plausible moral principles turn out to generate “deontic cycling”: sets of actions wherein I have stronger reason to do B than A, C than B, and A than C. Indeed, just about anything recognizable as commonsense morality generates deontic cycling. This matters for two reasons. First, it creates a problem for the widely held view that agent-centered rankings can square consequentialism with commonsense morality. Second, it forces a choice between some deeply plausible views (...) about rationality—wherein someone cannot have stronger reason to do A than B, B than C, and C than A—and commonsense morality.

According to one view of alethic modality, to say that something is necessary is to say that we must take that thing to be true according to rules of thinking or linguistic rules. In other words, alethic modality is reduced to deontic modality with respect to thoughts or language. This view has been argued to have many philosophical advantages over the traditional view that takes alethic modality to describe something in the world. In this paper, I (...) argue that the deontic view also enjoys a wide range of empirical supports from linguistics and psychology. (shrink)

Our goal here is to help identify the contextualist’s most worthy competitor to relativism. Recently, some philosophers of language and linguists have argued that, while there are contextualist-friendly semantic theories of deontic modals that fit with the relativist’s challenge data, the best such theories are not Lewis-Kratzer-style semantic theories. If correct, this would be important: It would show that the theory that has for many years enjoyed the status of the default view of modals in English and other (...) languages is in need of revision. Here we defend the default view by showing how a Kratzer-style semantics is able to make available readings of the relevant utterances that fit with the pretheoretical judgments opponents purport it cannot fully capture. Having established this, we turn to considering the more theoretical grounds proponents have offered for preferring their rival contextualist views. Here the question is to what extent such grounds favor semantic over what Korta and Perry call “near-side pragmatic” explanations of our judgments. In particular, we argue that our favored readings figure in near-side pragmatic explanations of those judgments that possess the methodological and theoretical advantages of systematicity and unity at least as well as, if not to a greater extent than, those of opponents who argue for their revised semantic theories on the basis of these advantages.

According to a recent challenge to Kratzer's canonical contextualist semantics for deontic modal expressions, no contextualist view can make sense of cases in which such a modal must be information-sensitive in some way. Here I show how Kratzer's semantics is compatible with readings of the targeted sentences that fit with the data. I then outline a general account of how contexts select parameter values for modal expressions and show, in terms of that account, how the needed, contextualist-friendly readings (...) might plausibly get selected in the challenge cases.

We present the inconsistency-adaptive deontic logic DP r , a nonmonotonic logic for dealing with conflicts between normative statements. On the one hand, this logic does not lead to explosion in view of normative conflicts such as O A ∧ O ∼A, O A ∧ P ∼A or even O A ∧ ∼O A. On the other hand, DP r still verifies all intuitively reliable inferences valid in Standard Deontic Logic (SDL). DP r interprets a given premise (...) set ‘as normally as possible’ with respect to SDL. Whereas some SDL-rules are verified unconditionally by DP r , others are verified conditionally. The latter are applicable unless they rely on formulas that turn out to behave inconsistently in view of the premises. This dynamic process is mirrored by the proof theory of DP r. (shrink)

Deontic logic is standardly conceived as the logic of true statements about the existence of obligations and permissions. In his last writings on the subject, G. H. von Wright criticized this view of deontic logic, stressing the rationality of norm imposition as the proper foundation of deontic logic. The present paper is an attempt to advance such an account of deontic logic using the formal apparatus of update semantics and dynamic logic. That is, we first (...) define norm systems and a semantics of norm performatives as transformations of the norm system. Then a static modal logic for norm propositions is defined on that basis. In the course of this exposition we stress the performative nature of (i) free choice permission, (ii) the sealing legal principle and (iii) the social nature of permission. That is, (i) granting a disjunctive permission means granting permission for both disjuncts; (ii) non-prohibition does not entail permission, but the authority can declare that whatever he does not forbid is thereby permitted; and (iii) granting permission to one person means that all others are committed to not prevent the invocation of that permission.

In his recent article “Deontic Cycling and the Structure of Commonsense Morality,” Tim Willenken argues that commonsense ethics allows for rational agents having both ranked reasons (A > B, B > C, and A > C) and cyclical reasons (A < B, B < C, and A > C). His goal is to show that not all plausible views are variations of consequentialism, as consequentialism requires ranked reasons. Here I argue apparent instances of deontic cycling in commonsense morality (...) are the byproducts of an incomplete characterizations of the cases in question. (shrink)

A shocking number of people worldwide currently suffer from malnutrition, disease, violence, and poverty. Their difficult lives evidence the intractability and pervasiveness of global need. In this paper I draw on recent developments in metaethical and normative theory to reframe one aspect of the conversation regarding whether moral agents are required to respond to the needs of distant strangers. In contrast with recent treatments of the issue of global poverty, as found in the work of Peter Singer (1972 and 2002), (...) who employs a broadly consequentialist framework focusing on suffering, and Thomas Pogge (2002), who inventively reframes the issue in terms of a negative duty not to harm, I explore this issue through an alternative approach: a social view of deontic moral reasons that features the idea of relational normativity. I address whether moral agents must respond to needy others by considering how the needs of distant strangers make implicit claims on those able to help them. Ultimately, I demonstrate why indifference in the face of global need is morally unacceptable, hence supporting the idea of an obligation that requires response to others’ basic needs. (shrink)

Abstract.The paper offers a critical survey of two main sorts of problems hindering the possibility of conceiving deontic logic as a suitable account of the logical behaviour of (sentences expressing) legal norms. The notion of “legal norm” is viewed as the main source of the first sort of problems: (a) the typological variety of legal norms requires an account both of the differing logical behaviour of (sentences expressing) differing legal norms, and of the relations which might hold amon them; (...) (b) the ontologic, semantic, and epistemic features of legal norms shed doubt on the very attempt to figure out a logical analysis of (sentences expressing) legal norms. The notion of “systemic legal validity” is viewed as the main source of the second sort of problems: Deontic logic does not provide suitable logical tools to account for legal phenomena like enactment, derogation, and conflicts between legal norms which rely on systemic legal validity.

One important objection to virtue ethical theories is that they apparently must account for the wrongness of a wrong action in terms of a lack of virtue (or presence of vice) in the agent, and not in terms of the effects of the action on its victim. We take such effects to ground deontic constraints on how we may act, and virtue theory appears unable to account for such constraints. I claim, however, that eudaimonist virtue theory can account for (...) wrongness in just this way. I draw on recent work by Stephen Darwall on the “second-person standpoint,” in which we see others as independent sources of claims on us —as sources of “deontic constraints.” We have reason to occupy that standpoint as a matter of virtue, and thus virtuous agents should and will have reasons to respect deontic constraints. I argue for this claim as an element of a plausible eudaimonist virtue theory, and rebut objections that the view misunderstands the nature of or reasons for respecting such constraints. (shrink)

Over the last fifteen years, linguists and philosophers of language have reexamined the canonical, Kratzerian semantics for modal expressions, with special attention paid to their epistemic and deontic uses. This article is an overview of the literature on deontic modal expressions. Section 1 provides an overview of the canonical semantics, noting some of its main advantages. Section 2 introduces a set of desiderata that have achieved the status of fixed points in the debates about whether the canonical semantics (...) is correct. These include the observations that deontic modal sentences have both deliberative and evaluative readings and both information-sensitive and -insensitive readings. Adequate resolutions of certain puzzles in deontic logic and resolving the Frege-Geach problem for Expressivism have also achieved this status. The third section provides an opinionated overview of some of the main extant rivals to the canonical semantics, including Cariani, Kaufmann, and Kaufmann’s (2013) complex contextualism , Yalcin’s (2012) Expressivism, Willer’s (2014) dynamic semantics, and Starr’s (2016) dynamic Expressivism. Section 4 provides an assessment of each of the views discussed in terms of the desiderata introduced in section 2. Section 5 is an overview of remaining issues that require more attention in the literature. (shrink)

Theories of epistemic justification are usually described as belonging to either deontological or nondeontological categories of justification with the former construing the concept of justification as involving the fulfillment of epistemic duty. Despite being the dominant view among traditional epistemologists, the deontological conception has been subjected to severe criticisms in the current literature for failing, among others, to do justice to the (alleged) truth-conducive character of epistemic justification. In this paper I set out to show that there is something (...) deeply unsatisfying about the way these different conceptions of justification are usually introduced and contrasted with each other leaving it unclear just what it is that renders a particular conception deontological. In particular I look at Alston's treatment of the issue, and show that his reasons for rejecting the deontological conception involve question-begging assumptions demonstrating, at best, the possibility of its divergence from truth-conductive justification. Far from being able to settle the issue one way or another, the arguments, I shall suggest actually seem to show some sort of tolerant pluralism in justification theory to be a live option. (shrink)

Deontic, as opposed to evaluative buck-passing theories seem to be easier to accept, since there appears to be an intimate connection between deontic properties, such as ‘ought’, ‘requirement’, and ‘permission’ on the one hand, and normative reasons on the other. However, it is far from obvious what, precisely, the connection consists in, and this topic has suffered from a paucity of discussion. This paper seeks to address that paucity by providing a novel deontic buck-passing view, one (...) that avoids the pitfalls both of the most straightforward view on the matter (what I call the “standard view”) as well as a recently articulated view, due to Matt Bedke. It does so by appealing first to the distinction between a reason for, and a reason against, and uses this distinction to clarify what are taken to be two fundamental, but distinct, deontic properties—ought and requirement. The resulting view allows us to capture these properties, the structural relations between them, and does so in a way that avoids making supererogation impossible. (shrink)

We discuss three aspects of the intuitionistic reformulation of Mally’s deontic logic that was recently proposed ). First, this reformulation is more similar to Standard Deontic Logic than appears at first sight: like Standard Deontic Logic, it is Kanger reducible and Anderson reducible to alethic logic and it has a semantical interpretation that can be read in deontic terms. Second, this reformulation has an extension that provides 100% of the theorems stated by Mally himself. Third, it (...) is interesting to view Mally’s original deontic logic as an extension of this reformulation. (shrink)

The deontic status of tautologies and contradictions is one of the major puzzles for authors of early works on deontic logic. It is well-known that von Wright addresses this problem by adopting a Principle of Deontic Contingency, which says that tautologies are not necessarily obligatory and contradictions are not necessarily forbidden. A more radical solution is proposed by Anderson within a reductionist approach to deontic logic and consists in restricting the range of application of deontic (...) modalities to contingent propositions. Anderson’s solution has not received much attention in the literature, despite reflecting a typical feature of ordinary deontic reasoning, where non-contingent propositions are rarely, if ever, taken into account. In the present article we explore some of its formal consequences, providing a taxonomy of the properties of the Andersonian operators of obligation and permission for contingent propositions, O′ and P′, in the class of normal alethic systems.

Within the scope of interest of deontic logic, systems in which names of actions are arguments of deontic operators (deontic action logic) have attracted less interest than purely propositional systems. However, in our opinion, they are even more interesting from both theoretical and practical point of view. The fundament for contemporary research was established by K. Segerberg, who introduced his systems of basic deontic logic of urn model actions in early 1980s. Nowadays such logics are (...) considered mainly within propositional dynamic logic (PDL). Two approaches can be distinguished: in one of them deontic operators are introduced using dynamic operators and the notion of violation, in the other at least some of them are taken as primitive. The second approach may be further divided into the systems based on Boolean algebra of actions and the systems built on the top of standard PDL. In the present paper we are interested in the systems of deontic action logic based on Boolean algebra. We present axiomatizations of six systems and set theoretical models for them. We also show the relations among them and the position of some existing theories on the resulting picture. Such a presentation allows the reader to see the spectrum of possibilities of formalization of the subject. (shrink)

The present volume is a sequel to Deontic Logic: Introductory and Systematic Readings : its purpose is to offer a view of some of the main directions of research in contemporary deontic logic. Most of the articles included in Introductory and Systematic Readings represent what may be called the standard modal approach to deontic logic, in which de on tic logic is treated as a branch of modal logic, and the normative concepts of obligation, permission and (...) prohibition are regarded as analogous to the "alethic" modalities necessity, possibility and impossibility. As Simo Knuuttila shows in his contribution to the present volume, this approach goes back to late medieval philosophy. Several 14th century philosophers observed the analogies between deontic and alethic modalities and discussed the deontic interpretations of various laws of modal logic. In contemporary deontic logic the modal approach was revived by G. H. von Wright's classic paper 'Deontic Logic'. Certain analogies between deontic and alethic modalities are obvious and uncontroversial, but the standard approach has often been criticized on the ground that it exaggerates the analogies and tends to ignore those features of normative concepts which distinguish them from other modalities.

Deontic Doxastic Constitutivism is the view that beliefs are constitutively governed by deontic norms. This roughly means that a full account and understanding of the nature of these mental attitudes cannot be reached unless one appeals to some norm of this type. My aim in this article is to provide an objection to such a conception of the normativity of belief. I argue that if some deontic norm is constitutive of belief, then the addressees of such (...) a norm are committed to a potentially infinite number of norms. Furthermore, if addressees are in the position to fulfill all such norms, they must also be able to hold a potentially infinite number of logically independent beliefs. Both these consequences are problematic if compared with limited human capacities to act and believe. (shrink)

In 1926, Mally presented the first formal system of deontic logic. His system had several consequences which Mally regarded as surprising but defensible. It also, however, has the consequence that A is obligatory if and only if A is the case, which is unacceptable from the point of view of any reasonable deontic logic. We describe Mally's system and discuss how it might reasonably be repaired.

This paper focuses on several issues that arise in Miranda Fricker?s book Epistemic injustice surrounding her claims about our (moral) culpability for perpetrating acts of testimonial injustice. While she makes frequent claims about moral culpability with respect to specific examples, she never addresses the issue in its full generality, and we are left to extrapolate her general view about moral culpability for acts of testimonial injustice from these more restricted and particular claims. Although Fricker never describes testimonial injustice in (...) such terms, I argue that the fundamental wrong done in acts of testimonial injustice is a form of negligence. Once we understand testimonial injustice in this way, it is easier to see when and why we are culpable for perpetrating such injustices. Indeed, explicitly recognizing testimonial injustice as a form of negligence solves several problems for Fricker?s view, which are elucidated briefly along the way. However, construing testimonial injustice as a form of negligence has a cost as well. It highlights the fact that the normative core of Fricker?s view is deontological, rather than virtue-theoretic. Fricker claims to be offering a theory of the virtue of testimonial justice along the model of current virtue theories in epistemology, yet it seems that there is no compelling reason to think of what she has offered as a virtue theory, at least not on the model of virtue theories that one finds in epistemology. This is not to say that her view is any less plausible for not being a virtue theory. But calling it a virtue theory affects how one interprets its various claims, and tends to lead one away from, rather than toward, a proper understanding of the deep deontological nature of her account.

Philosophical debate about the meaning of normative terms has long been pulled in two directions by the apparently competing ideas: (i) ‘ought’s do not describe what is actually the case but rather prescribe possible action, thought, or feeling, (ii) all declarative sentences deserve the same general semantic treatment, e.g. in terms of compositionally specified truth conditions. In this paper, I pursue resolution of this tension by rehearsing the case for a relatively standard truth-conditionalist semantics for ‘ought’ conceived as a necessity (...) modal and proposing a revision to it motivated by the distinctively prescriptive character of some deontic modals. In my view, this puts pressure on a popular conception of one of the core debates of metanormative theory between realists and antirealists. To make good on this claim, I go on to explore two very general ways we might interpret the results of compositional semantics—“representationalism” and “inferentialism”—in order to argue that, contrary to what is generally assumed, both can capture the special prescriptivity of ‘ought’ and both can countenance compositionally specified and informative truth-conditions for ought-sentences. Hence, my main thesis is that the deciding factor between them should not be which of ideas (i) and (ii) we are more impressed by but rather what we think of the relative merits of how representationalism and inferentialism respect these ideas. I’m inclined to favor an antirealist form of inferentialism, but the task I’ve set myself here is mainly to articulate the view in the context of metanormative theory and the semantics of deontic modals rather than try to defend it fully. To this purpose, towards the end I also briefly compare and contrast inferentialism with a third “ideationalist” metasemantic view, which may be an attractive home for some sophisticated versions of metanormative expressivism. Depending on how expressivism is worked out, it may be completely compatible with and so perhaps usefully combined with inferentialism or it may offer a competing way to respect ideas (i) and (ii).

Abstract.The authors concentrate on the analysis of the concept of permission. After a general account of differing concepts of permission both with regard to different legal theories and to different legal ideologies, they argue in favour of a “radical” imperativism which leaves no place for permissive norms. Thus, in contrast with the logic of normative language (LNL) purported by Alchourrón and Bulygin, the authors figure out a system of deontic logic ‐ supplemented by devices of the possible world semantics (...) ‐ according to which a normative system (N) is conceived as a set of logical consequences of a certain finite set of basic obligations and no room is left either for the concept of weak permission or for the concept of strong permission. Finally the authors raise some criticisms concerning the view maintained by Alchourron and Bulygin on strong permission.*. (shrink)

Several years ago I came across a marvelous little paper in which Hector-Neri Castaneda shows that standard versions of act utilitarian l ism are formally incoherent. I was intrigued by his argument. It had long seemed to me that I had a firm grasp on act utilitarianism. Indeed, it had often seemed to me that it was the clearest and most attractive of normative theories. Yet here was a simple and relatively uncontrover sial argument that showed, with only some trivial (...) assumptions, that the doctrine is virtually unintelligible. The gist of Castaneda's argument is this: suppose we understand act utilitarianism to be the view that an act is obligatory if and only if its utility exceeds that of each alternative. Suppose it is obligatory for a certain person to perform an act with two parts - we can call it 'A & B'. Then, obviously enough, it is also obligatory for this person to perform the parts, A and B. If act utilitarianism were true, we appar ently could infer that the utility of A & B is higher than that of A, and higher than that of B (because A & B is obligatory, and the other acts are alternatives to A & B).

If a native of India asserts "Killing cattle is wrong" and a Nebraskan asserts "Killing cattle is not wrong", and both judgments agree with their respective moralities and both moralities are internally consistent, then the moral relativist says both judgments are fully correct. At this point relativism bifurcates. One branch which we call content relativism denies that the two people are contradicting each other. The idea is that the content of a moral judgment is a function of the overall moral (...) point of view from which it proceeds. The second branch which we call truth value relativism affirms that the two judgments are contradictory. Truth value relativism appears to be logically incoherent. How can contradictory judgments be fully correct? For though there will be a sense of correctness in which each judgment is correct — namely by that of being correct relative to the morality relative to which each was expressed — if contradictory, the judgments cannot both be true, and thus cannot both be correct in this most basic sense of correctness. We defend truth value relativism against this sort of charge of logical incoherence by showing it can be accommodated by the existing semantical metatheories of deontic logic. Having done this we go on to argue that truth value relativism is the best version of relativism. (shrink)

Philosophers like G.H. von Wright and D. Makinson have pointed to serious challenges regarding the foundations of deontic logic. In this paper, I suggest that to deal successfully with these challenges a reconsideration of the research program of the discipline is useful. Some problems that have troubled this particular field of logical study for decades may disappear or appear more tractable if we view them from the perspective of a language game introduced by D. Lewis involving three characters: (...) the Master, the Slave and the Kibitzer. The adoption of this perspective opens a natural approach to a new layout of the domain of deontic studies. I propose dividing deontic logic into six sub-areas which are distinguished by their focus on the different idioms typical of the individual players, by conceiving the language game as either being static or as dynamic and by the aims of the logical inquiry. What kind of insights the proposed perspective provides is illustrated by an analysis of the so-called Ross paradox—a problem that has troubled deontic logic since its origins and, though it was many times pronounced solved, still keeps coming back ‘alive and kicking’.

Despite growing appreciation in recent decades of the importance of shared intentional mental states as a foundation for everything from divergences in primate evolution, to the institution of communal norms, to trends in the development of modernity as a socio-political phenomenon, we lack an adequate understanding of the relationship between individual and shared intentionality. At the same time, it is widely appreciated that deontic reasoning concerning what ought, may, and ought not be done is, like reasoning about our intentions, (...) an exercise of practical rationality. Taking advantage of this fact, I use a plan-theoretic semantics for the deontic modalities as a basis for understanding individual and shared intentions. This results in a view that accords well with what we currently have reason to believe about the phylogenetic and ontogenetic development of norm psychology and shared intentionality in human beings, and where original intentionality can be understood in terms of the shared intentionality of a community.

Recently, Bengt Hansson presented a paper about dyadic deontic logic,2 criticizing some purely axiomatic systems of dyadic deontic logic and proposing three purely semantical systems of dyadic deontic logic which he confidently called dyadic standard systems of deontic logic (DSDL1–3). Here I shall discuss the third by far most interesting system DSDL3 which is operating with preference relations. First, I shall describe this semantical system (Sections 1.1–1.3). Then I shall give an axiomatic system (Section 1.4) which (...) is proved to be correct (Section 2) and complete (Section 3) with respect to Hansson's semantics. Finally, in face of these results Hansson's semantics will be discussed from a more intuitive standpoint. After emphasizing its intuitive attractiveness (Section 4.1) I will show that two objections often discussed in connection with preference relations do not apply to it (Section 4.2 and 4.3); more precisely, I will show that the connectedness condition for preference relations can be dropped and that, in a sense, it is not necessary to compare two possible worlds differing in infinitely many respects. (What exactly is meant by this, will become clear later on.) Yet there is a third objection to Hansson's semantics which points to a real intuitive inadequacy of DSDL3. A way of removing this inadequacy, which corresponds to Hansson's own intuitions as well as to familiar metaethical views, is suggested, but not technically realized (Section 4.4). In the last section (section 4.5) I shall briefly show that DSDL3 is decidable, as expected. (shrink)

In [1] J.-Y. Bèziau formulated a logic called Z. Bèziau’s idea was generalized independently in [6] and [7]. A family of logics to which Z belongs is denoted in [7] by K. In particular; it has been shown in [6] and [7] that there is a correspondence between normal modal logics and logics from the class K. Similar; but only partial results has been obtained also for regular logics. In a logic N has been investigated in the language with negation; (...) implication; conjunction and disjunction by axioms of positive intuitionistic logic; the right-to-left part of the second de Morgan law; and the rules of modus ponens and contraposition. From the semantical point of view the negation used by Došen is the modal operator of impossibility. It is known this operator is a characteristic of the modal interpretation of intuitionistic negation. In the present paper we consider an extension of N denoted by N+. We will prove that every extension of N+ that is closed under the same rules as N+; corresponds to a regular logic being an extension of the regular deontic logic D21. The proved correspondence allows to obtain from soundnesscompleteness result for any given regular logic containing D2, similar adequacy theorem for the respective extension of the logic N+.

This paper compares two ways of formalising defeasible deontic reasoning, both based on the view that the issues of conflicting obligations and moral dilemmas should be dealt with from the perspective of nonmonotonic reasoning. The first way is developing a special nonmonotonic logic for deontic statements. This method turns out to have some limitations, for which reason another approach is recommended, viz. combining an already existing nonmonotonic logic with a deontic logic. As an example of this (...) method the language of Reiter's default logic is extended to include modal expressions, after which the argumentation framework in default logic of [20, 22] is used to give a plausible logical analysis of moral dilemmas and prima facie obligations.

Traditional moral theories appear to be unable to give a credible account of the relationship between deontic and axiological concepts, i.e. duty and value. Of the two traditional solutions to this problem, one emphasises the independence of the two realms, whereas Mill argues that duty is definable in terms of goodness. In this paper I present Meinong's Law of Omission which offers, in my opinion, a promising alternative to these two traditional views.

In this paper, we axiomatize the deontic logic in Fusco (2015), which uses a Stalnaker-inspired account of diagonal acceptance and a two-dimensional account of disjunction to treat Ross’s Paradox and the Puzzle of Free Choice Permission. On this account, disjunction-involving validities are a priori rather than necessary. We show how to axiomatize two-dimensional disjunction so that the introduction/elimination rules for boolean disjunction can be viewed as one-dimensional projections of more general two-dimensional rules. These completeness results help make explicit the (...) restrictions Fusco’s account must place on free-choice inferences. They are also of independent interest, as they raise difficult questions about how to “lift” a Kripke frame for a one-dimensional modal logic into two dimensions. (shrink)

Some philosophers have developed comprehensive interactive models that purport to exhibit the various normative constraints that agents need to adopt in order to achieve what otherwise would be an unattainable and unsustainable social order. Robert Brandom’s semantic inferentialism purports to show how a rational construction of social coordination is enacted and maintained through specific mappings that agents make of each other’s commitments (beliefs) and entitlements (justified beliefs). Strongly influenced by Brandom’s account, Joseph Heath reconstructs a number of historically emergent (...) class='Hi'>deontic constraints that solve what are otherwise unsolvable game-theoretic problems in the maintenance of the social order. But both accounts omit a sufficient analysis of the way in which individual agents, who comprise the normative order, are effectively addressed by norms when they act. How does an agent, who is facing a unique interactive situation with more than one normative path to choose, make a decision? One solution, attractive to some continental thinkers, is to appeal to an innate irrational component of decision-making that lies outside of rational bounds (e.g., Nietzsche’s will to power or Adorno’s das Hinzutrentende). The model I will defend lies in an existential account of agency that occupies a middle ground between a pure naturalism (where instinct dominates) and a pure regularism, or “normativism” (where reason dominates). The existential model asserts that the given normative field within which an agent operates conditions the formation of the agent’s intention to act but does not determine the effecting of an action as such — whether individual or collective. On this model, the specification of the acting or not acting on the normative intention is determined only retrospectively on the basis of what the agent actually did in a way that is in principle public and observable. Thus the content of the agency can be reconstructed only historically. The embodied character of the agent is what makes the action relatable to the sum of conditions that were co-determinative of the action at the time it occurred. The advantage of this view is that it does not overreach the highly limited access that we have to the inner workings of intentions to act while at the same time providing an account of agency independent of simply the agent’s relation to norms.

The ideal world semantics of standard deontic logic identifies our obligations with how we would act in an ideal world. However, to act as if one lived in an ideal world is bad moral advice, associated with wishful thinking rather than well-considered moral deliberation. Ideal world semantics gives rise to implausible logical principles, and the metaphysical arguments that have been put forward in its favour turn out to be based on a too limited view of truth-functional representation. It (...) is argued that ideal world semantics should be given up in favour of other, more plausible uses of possible worlds for modelling normative subject-matter. (shrink)

This article distinguishes between a telic and a deontic version of Derek Parfit's influential Priority View. Employing the distinction, it shows that the existence of variations in how intrapersonal and interpersonal conflicts should be resolved fails to provide a compelling case in favour of relational egalitarianism and against all pure versions of the Priority View. In addition, the article argues that those variations are better understood as providing counterevidence to certain distribution-sensitive versions of consequentialism.

The programmatic statement put forward in von Wright's last works on deontic logic introduces the perspective of logical pragmatics, which has been formally explicated here and extended so to include the role of norm-recipient as well as the role of norm-giver. Using the translation function from the language of deontic logic to the language of set-theoretical approach, the connection has been established between the deontic postulates, on one side, and the perfection properties of the norm-set and the (...) counter-set, on the other side. In the study of conditions of rational norm-related activities it has been shown that diverse dynamic second-order norms related to the concept of the consistency norm-system hold: -- the norm-giver ought to restore ``classical'' consistency by revising an inconsistent system, -- the norm-recipient ought to preserve an inconsistent system by revision of its logic so that inconsistency does not imply destruction of the system. Dialetheic deontic logic of Priest is a suitable logic for the purpose since it preserves other perfection properties of the system. (shrink)
