  1. A Deontic Logic for Programming Rightful Machines: Kant’s Normative Demand for Consistency in the Law.Ava Thomas Wright - 2023 - Logics for Ai and Law: Joint Proceedings of the Third International Workshop on Logics for New-Generation Artificial Intelligence (Lingai) and the International Workshop on Logic, Ai and Law (Lail).
    In this paper, I set out some basic elements of a deontic logic with an implementation appropriate for handling conflicting legal obligations for purposes of programming autonomous machine agents. Kantian justice demands that the prescriptive system of enforceable public laws be consistent, yet statutes or case holdings may often describe legal obligations that contradict; moreover, even fundamental constitutional rights may come into conflict. I argue that a deontic logic of the law should not try to work around such (...)

  2. Une approche volontariste du droit naturel et de la contradiction. Une façon de bâtir la notion de hiérarchie dans la pensée latine médiévale.Luca Parisoli - 2013 - Revus 21:219-236.
    L’analyse des juristes médiévaux nous montre comment la manipulation des contradictions déontiques prima facie est associée, dans l’argumentation interprétative, à la théorie de la légitimité de la hiérarchie normative, entendue non seulement comme instrument politique mais aussi et essentiellement comme un instrument de rationalité au sein d’une science juridique orientée vers une théologie politique. La notion de droit naturel telle qu’elle apparaît dans certains documents emblématiques dont le Decretum de Gratien du XIIe s., ne peut être réduite au modèle intellectualiste (...)

    We show how some model-theoretical devices (local reasoning, modes of presentation, an additional accessibility relation) can be combined in first-order modal logic to formalize the consequence relation that includes de dicto and de re contradictory beliefs. Instead of special ``sense objects'', appearances of objects in an agent's belief are introduced and presented as ordered pairs consisting of an object and an individual constant. A non-classical identity relation is applied. A relation S on the set of possible worlds is introduced, which (...)

  4. L'etica del Novecento. Dopo Nietzsche.Sergio Cremaschi - 2005 - Roma RM, Italia: Carocci.
    TWENTIETH-CENTURY ETHICS. AFTER NIETZSCHE -/- Preface This book tells the story of twentieth-century ethics or, in more detail, it reconstructs the history of a discussion on the foundations of ethics which had a start with Nietzsche and Sidgwick, the leading proponents of late-nineteenth-century moral scepticism. During the first half of the century, the prevailing trends tended to exclude the possibility of normative ethics. On the Continent, the trend was to transform ethics into a philosophy of existence whose self-appointed task was (...)

  5. Atonement’s Axiological Boundaries.Yishai Cohen - 2017 - European Journal for Philosophy of Religion 9 (3):177-195.
    According to the Felix Culpa Theodicy, worlds containing atonement and incarnation are of such great value that God is justified in actualizing such a world, despite all of the moral evil that has accompanied it. Focusing upon Alvin Plantinga’s articulation of this theodicy, I argue against FCT on the basis of normative ethical considerations. On the one hand, the deontic status of at least some actions depends upon the consequences of those actions. On the other hand, the existence of (...)

  6. On Floating Conclusions.Daniela Schuster, Jan Broersen & Henry Prakken - 2023 - Deontic Logic and Normative Systems, 16Th International Conference, Deon 2023.
    When there are two lines of argument that contradict each other but still end up with the same conclusion, this conclusion is called a floating conclusion. It is an open topic in skeptical defeasible reasoning if floating conclusions ought to be accepted. Inter- estingly, the answer seems to be changing for different examples. In this paper, we propose a solution for explaining the different treatments of the floating conclusion in the various examples from the literature. We collect the examples from (...)

  7. Deontic Logics based on Boolean Algebra.Pablo F. Castro & Piotr Kulicki - 2013 - In Robert Trypuz (ed.), Krister Segerberg on Logic of Actions. Dordrecht, Netherland: Springer Verlag.
    Deontic logic is devoted to the study of logical properties of normative predicates such as permission, obligation and prohibition. Since it is usual to apply these predicates to actions, many deontic logicians have proposed formalisms where actions and action combinators are present. Some standard action combinators are action conjunction, choice between actions and not doing a given action. These combinators resemble boolean operators, and therefore the theory of boolean algebra offers a well-known athematical framework to study the properties (...)

    It is well known that systems of action deontic logic emerging from a standard analysis of permission in terms of possibility of doing an action without incurring in a violation of the law are subject to paradoxes. In general, paradoxes are acknowledged as such if we have intuitions telling us that things should be different. The aim of this paper is to introduce a paradox-free deontic action system by (i) identifying the basic intuitions leading to the emergence of (...)

  10. Deontic Modals and Probability: One Theory to Rule Them All?Fabrizio Cariani - 2016 - In Nate Charlow & Matthew Chrisman (eds.), Deontic Modality. New York, NY: Oxford University Press.
    This paper motivates and develops a novel semantic framework for deontic modals. The framework is designed to shed light on two things: the relationship between deontic modals and substantive theories of practical rationality and the interaction of deontic modals with conditionals, epistemic modals and probability operators. I argue that, in order to model inferential connections between deontic modals and probability operators, we need more structure than is provided by classical intensional theories. In particular, we need probabilistic (...)

    There has been a recent surge of work on deontic modality within philosophy of language. This work has put the deontic logic tradition in contact with natural language semantics, resulting in significant increase in sophistication on both ends. This chapter surveys the main motivations, achievements, and prospects of this work.

    Explaining Deontic Status by Good Reasoning.Ulf Hlobil - forthcoming - Erkenntnis.
    This paper offers an account of deontic normativity in terms of attributive goodness. An action is permissible for S in C just in case there is a good practical inference available to S in C that results in S performing (or intending to perform) the action. The standards of goodness for practical inferences are determined by what is a good or bad exercise of the human capacity of practical reason, which is an attributive (and not a deontic) assessment.

  13. Deontic logic as a study of conditions of rationality in norm-related activities.Berislav Žarnić - 2016 - In Olivier Roy, Allard Tamminga & Malte Willer (eds.), Deontic Logic and Normative Systems. London, UK: College Publications. pp. 272-287.
    The program put forward in von Wright's last works defines deontic logic as ``a study of conditions which must be satisfied in rational norm-giving activity'' and thus introduces the perspective of logical pragmatics. In this paper a formal explication for von Wright's program is proposed within the framework of set-theoretic approach and extended to a two-sets model which allows for the separate treatment of obligation-norms and permission norms. The three translation functions connecting the language of deontic logic with (...)

  14. Two puzzles about deontic necessity.Dilip Ninan - 2005 - In J. Gajewski, V. Hacquard, B. Nickel & S. Yalcin (eds.), New Work on Modality, MIT Working Papers in Linguistics.
    The deontic modal must has two surprising properties: an assertion of must p does not permit a denial of p, and must does not take past tense complements. I first consider an explanation of these phenomena that stays within Angelika Kratzer’s semantic framework for modals, and then offer some reasons for rejecting that explanation. I then propose an alternative account, according to which simple must sentences have the force of an imperative.

  15. Contrary-to-Duty Scenarios, Deontic Dilemmas, and Transmission Principles.Benjamin Kiesewetter - 2018 - Ethics 129 (1):98-115.
    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 contrary-to-duty scenarios, (...)

  16. Norm Performatives and Deontic Logic.Rosja Mastop - 2011 - European Journal of Analytic Philosophy 7 (2):83-105.
    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 (...)

    This study draws on deontic justice theory to examine an unexplored socioemotional micro-foundation of corporate social responsibility (CSR), namely anticipated guilt, in an effort to improve our understanding of employees’ moral reactions to their organization’s CSR. We empirically investigate whether environmental CSR induces anticipated guilt (i.e., concerns about future guilt for not contributing to organizational CSR) leading to organizational environmental citizenship behavior. We also consider two boundary conditions related to the social nature of anticipated guilt: line manager support for (...)

    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 (...)

    Deontic constraints prohibit an agent performing acts of a certain type even when doing so will prevent more instances of that act being performed by others. In this article I show how deontic constraints can be interpreted as either maximizing or non-maximizing rules. I then argue that they should be interpreted as maximizing rules because interpreting them as non-maximizing rules results in a problem with moral advice. Given this conclusion, a strong case can be made that consequentialism provides (...)

    Though there have been productive interactions between moral philosophers and deontic logicians, there has also been a tradition of neglecting the insights that the fields can offer one another. The most sustained interactions between moral philosophers and deontic logicians have notbeen systematic but instead have been scattered across a number of distinct and often unrelated topics. This chapter primarily focuses on three topics. First, we discuss the “actualism/possibilism” debate which, very roughly, concerns the relevance of what one will (...)

In this paper, we entirely do one completely destructive thing and partly do one not entirely constructive thing. The first thing: we argue that there is an unrecognized gap between the claim that the function of deontic evaluation is to guide action and attempts to put that claim to use.

  22. A Contradiction of the Right Kind: Convenience Killing and Kant’s Formula of Universal Law.Pauline Kleingeld - 2019 - Philosophical Quarterly 69 (274):64-81.
    One of the most important difficulties facing Kant’s Formula of Universal Law (FUL) is its apparent inability to show that it is always impermissible to kill others for the sake of convenience. This difficulty has led current Kantian ethicists to de-emphasize the FUL or at least complement it with other Kantian principles when dealing with murder. The difficulty stems from the fact that the maxim of convenience killing fails to generate a ‘contradiction in conception’, producing only a ‘contradiction (...)

    Kant’s most prominent formulation of the Categorical Imperative, known as the Formula of Universal Law (FUL), is generally thought to demand that one act only on maxims that one can will as universal laws without this generating a contradiction. Kant's view is standardly summarized as requiring the 'universalizability' of one's maxims and described in terms of the distinction between 'contradictions in conception' and 'contradictions in the will'. Focusing on the underappreciated significance of the simultaneity condition included in the FUL, (...)

    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 (...)

    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 (...)

    Contrastivism about ‘ought’ holds that ‘ought’ claims are relativized, at least implicitly, to sets of mutually exclusive but not necessarily jointly exhaustive alternatives. This kind of theory can solve puzzles that face other linguistic theories of ‘ought’, via the rejection or severe restriction of principles that let us make inferences between ‘ought’ claims. By rejecting or restricting these principles, however, the contrastivist takes on a burden of recapturing acceptable inferences that these principles let us make. This paper investigates the extent (...)

    In the paper we present a formal system motivated by a specific methodology of creating norms. According to the methodology, a norm-giver before establishing a set of norms should create a picture of the agent by creating his repertoire of actions. Then, knowing what the agent can do in particular situations, the norm-giver regulates these actions by assigning deontic qualifications to each of them. The set of norms created for each situation should respect (1) generally valid deontic principles (...)

    Coastal protection is crucial to human development since the ocean has many values associated with the economy, ecosystem, and culture.

The logic is based upon atemporal utilitarian STIT logic. Yet, the logic presented here will be neutral: instead of committing ourselves to utilitarian theories, we prove the logic TDS sound and complete with respect to relational frames not employing any utilitarian function. We demonstrate how these neutral frames can be transformed into utilitarian temporal frames, while (...)

    I propose a unified solution to two puzzles: Ross's puzzle and free choice permission. I begin with a pair of cases from the decision theory literature illustrating the phenomenon of act dependence, where what an agent ought to do depends on what she does. The notion of permissibility distilled from these cases forms the basis for my analysis of 'may' and 'ought'. This framework is then combined with a generalization of the classical semantics for disjunction — equivalent to Boolean disjunction (...)

    In this paper, I offer a close reading of Wittgenstein's remarks on inconsistency, mostly as they appear in the Lectures on the Foundations of Mathematics. I focus especially on an objection to Wittgenstein's view given by Alan Turing, who attended the lectures, the so-called ‘falling bridges’-objection. Wittgenstein's position is that if contradictions arise in some practice of language, they are not necessarily fatal to that practice nor necessitate a revision of that practice. If we then assume that we have adopted (...)

    This paper introduces two new paradoxes for standard deontic logic (SDL). They are importantly related to, but distinct from Ross' paradox. These two new paradoxes for SDL are the simple weakening paradox and the complex weakening paradox. Both of these paradoxes arise in virtue of the underlaying logic of SDL and are consequences of the fact that SDL incorporates the principle known as weakening. These two paradoxes then show that SDL has counter-intuitive implications related to disjunctive obligations that arise (...)

    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 contrast with recent treatments of the issue of global poverty, as found in the work of Peter Singer (1972 and 2002), (...)

  44. Dialectical Contradictions and Classical Formal Logic.Inoue Kazumi - 2014 - International Studies in the Philosophy of Science 28 (2):113-132.
    A dialectical contradiction can be appropriately described within the framework of classical formal logic. It is in harmony with the law of noncontradiction. According to our definition, two theories make up a dialectical contradiction if each of them is consistent and their union is inconsistent. It can happen that each of these two theories has an intended model. Plenty of examples are to be found in the history of science.

  45. Contradictions at the borders.David Ripley - 2011 - In Rick Nouwen, Robert van Rooij, Uli Sauerland & Hans-Christian Schmitz (eds.), Vagueness in Communication. Springer. pp. 169--188.
    The purpose of this essay is to shed some light on a certain type of sentence, which I call a borderline contradiction. A borderline contradiction is a sentence of the form F a ∧ ¬F a, for some vague predicate F and some borderline case a of F , or a sentence equivalent to such a sentence. For example, if Jackie is a borderline case of ‘rich’, then ‘Jackie is rich and Jackie isn’t rich’ is a borderline (...). Many theories of vague language have entailments about borderline contradictions; correctly describing the behavior of borderline contradictions is one of the many tasks facing anyone offering a theory of vague language. Here, I first briefly review claims made by various theorists about these borderline contradictions, attempting to draw out some predictions about the behavior of ordinary speakers. Second, I present an experiment intended to gather relevant data about the behavior of ordinary speakers. Finally, I discuss the experimental results in light of several different theories of vagueness, to see what explanations are available. My conclusions are necessarily tentative; I do not attempt to use the present experiment to demonstrate that any single theory is incontrovertibly true. Rather, I try to sketch the auxiliary hypotheses that would need to be conjoined to several extant theories of vague language to predict the present result, and offer some considerations regarding the plausibility of these various hypotheses. In the end, I conclude that two of the theories I consider are better-positioned to account for the observed data than are the others. But the field of logically-informed research on people’s actual responses to vague predicates is young; surely as more data come in we will learn a great deal more about which (if any) of these theories best accounts for the behavior of ordinary speakers.

  46. The Epistemic and the Deontic Preface Paradox.Lina M. Lissia & Jan Sprenger - forthcoming - Philosophical Quarterly.
    This paper generalizes the preface paradox beyond the conjunctive aggregation of beliefs and constructs an analogous paradox for deontic reasoning. The analysis of the deontic case suggests a systematic restriction of intuitive rules for reasoning with obligations. This proposal can be transferred to the epistemic case: it avoids the preface and the lottery paradox and saves one of the two directions of the Lockean Thesis (i.e., high credence is sufficient, but not necessary for rational belief). The resulting account (...)

  47. Frankfurt Cases and Alternate Deontic Categories.Samuel Kahn - 2023 - Dialogue 62 (3):539-552.
    In Harry Frankfurt’s seminal “Alternate Possibilities and Moral Responsibility,” he advances an argument against the Principle of Alternate Possibilities: if an agent is responsible for performing some action, then she is able to do otherwise. However, almost all of the Frankfurt cases in this literature involve impermissible actions. In this article, I argue that the failure to consider other deontic categories exposes a deep problem, one that threatens either to upend much current moral theorizing or to upend the relevance (...)

  48. Semantics for Deontic Modals.J. L. Dowell - forthcoming - In Ernest Lepore & Una Stojnic (eds.), Oxford Handbook of Contemporary Philosophy of Language. Oxford University Press.
    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 (...)

  49. Absolute Contradiction, Dialetheism, and Revenge.Francesco Berto - 2014 - Review of Symbolic Logic 7 (2):193-207.
    Is there a notion of contradiction—let us call it, for dramatic effect, “absolute”—making all contradictions, so understood, unacceptable also for dialetheists? It is argued in this paper that there is, and that spelling it out brings some theoretical benefits. First it gives us a foothold on undisputed ground in the methodologically difficult debate on dialetheism. Second, we can use it to express, without begging questions, the disagreement between dialetheists and their rivals on the nature of truth. Third, dialetheism has (...)

    This paper outlines a semantic account of attitude reports and deontic modals based on cognitive and illocutionary products, mental states, and modal products, as opposed to the notion of an abstract proposition or a cognitive act.
