  1. Violation games: a new foundation for deontic logic ★.Leendert van der Torre - 2010 - Journal of Applied Non-Classical Logics 20 (4):457-477.
    In this paper I propose violation games as the basis of formal logics to represent and reason about norms, i.e. as the foundation of deontic logic. Deontic logic is an applied non-classical logic reflecting a way in which we conceptualize normative reasoning. By introducing violation games as a fundamental principle of deontic logic, I am introducing a new way of looking at familiar problems in normative reasoning, with the aim of introducing a new approach for handling norms in intelligent systems.

  • Dyadic deontic logic and semantic tableaux.Daniel Rönnedal - 2009 - Logic and Logical Philosophy 18 (3-4):221-252.
    The purpose of this paper is to develop a class of semantic tableau systems for some dyadic deontic logics. We will consider 16 different pure dyadic deontic tableau systems and 32 different alethic dyadic deontic tableau systems. Possible world semantics is used to interpret our formal languages. Some relationships between our systems and well known dyadic deontic logics in the literature are pointed out and soundness results are obtained for every tableau system. Completeness results are obtained for all 16 pure (...)

    The aim of the paper is to point out the modelling choices that lead to different systems of deontic action logic. A kind of a roadmap is presented. On the one hand it can help the reader to find the deontic logic appropriate for an intended application relying on the information considering the way in which a deontic logic represents actions and how it characterises deontic properties in relation to (the representation of) actions. On the other hand it is a (...)

    . The author conceives rules as action‐determining ideas. They are general and of hypothetical form, and they are of three semantic types: descriptive, technological, and normative rules. The most important categorisation of normative rules is the distinction between rules of behaviour and power‐conferring rules. Both kinds of rules are necessary to establish institutions. Principles are a special kind of normative rules. The social existence of normative rules is connected with their institutionalisation as frames for action. The dynamics of rules is (...)

    Metaethics is the study of metaphysics, epistemology, the philosophy of mind, and the philosophy of language, insofar as they relate to the subject matter of moral or, more broadly, normative discourse – the subject matter of what is good, bad, right or wrong, just, reasonable, rational, what we must or ought to do, or otherwise. But out of these four ‘core’ areas of philosophy, it is plausibly the philosophy of language that is most central to metaethics – and not simply (...)

    I was quite excited when I first read Restall and Russell’s (2010) paper. For two reasons. First, because the paper provides rigorous formulations and formal proofs of implication barrier the- ses, namely “theses [which] deny that one can derive sentences of one type from sentences of another”. Second (and primarily), because the paper proves a general theorem, the Barrier Con- struction Theorem, which unifies implication barrier theses concerning four topics: generality, necessity, time, and normativity. After thinking about the paper, I (...)

    In moral dilemmas, where circumstances prevent two or more equally justified prima facie ethical requirements from being fulfilled, it is often maintained that, since the agent cannot do both, conjoint obligation is overridden by Kant's principle that ought implies can, but that the agent nevertheless has a disjunctive obligation to perform one of the otherwise obligatory actions or the other. Against this commonly received view, it is demonstrated that although Kant's ought-can principle may avoid logical inconsistency, the principle is incompatible (...)

    Scientists from various disciplines have begun to focus attention on the psychology and biology of human morality. One research program that has recently gained attention is universal moral grammar (UMG). UMG seeks to describe the nature and origin of moral knowledge by using concepts and models similar to those used in Chomsky's program in linguistics. This approach is thought to provide a fruitful perspective from which to investigate moral competence from computational, ontogenetic, behavioral, physiological and phylogenetic perspectives.

However it is important to distinguish between three versions of the Autonomy of Ethics: Ontological, Semantic and Ontological.

The principle of commitment implying obligation is proven in a specific logic of action preference which is a generalization of Meyer 's dynamic deontic logic. In the proposed formalism, an agent's commitment to goals is considered as a special kind of action which can change one's deontic preference andone's obligation to take some action is based on the preference and the effects of the action.

    The advantages and disadvantages of formalization in philosophy are summarized. It is concluded that formalized philosophy is an endangered speciality that needs to be revitalized and to increase its interactions with non-formalized philosophy. The enigmatic style that is common in philosophical logic must give way to explicit discussions of the problematic relationship between formal models and the philosophical concepts and issues that motivated their development.

    According to Act Consequentialism, an act is right if and only if its outcome is not worse than the outcome of any alternative to that act. This view, however, leads to deontic paradoxes if the alternatives to an act are all other acts that can be done in the situation. A typical response is to only apply this rightness criterion to maximally specific acts and to take the alternatives to a maximally specific act to be the other maximally specific acts (...)

Two concerns are noted: the reducibility of P to O, and the inadequacy of P to convey a full permission in a social setting. Drawing on resources from the Hohfeldian analytical framework, the relational and aggregate features of permission are explored, and an aggregate conception of (...)

We start by discussing some philosophical ideas behind the approach; in particular, the difference between the set of possible worlds in which a formula is true (its intension) and the semantic content of a formula (its hyperintension), which is captured in a rigorous way in hyperintensional models. Next, we rigorously specify the approach and provide a fundamental completeness theorem. Moreover, we analyse examples (...)

  • The is-ought gap and the substitution criterion.Melvin Chen - 2021 - South African Journal of Philosophy 40 (3):254-264.
    Ever since its formulation by Hume, the idea of an inferential barrier between non-ethical (“is”) propositions and ethical (“ought”) propositions (also known as Hume’s is-ought thesis) has received much philosophical attention. Prior’s Paradox appears to demonstrate that the ban on “is”-“ought” inferences is violated in every possible instance, from which it follows that Hume’s is-ought thesis must be false. In this article, I will formulate a logically rigorous version of Hume’s is-ought thesis, introduce Prior-style counterexamples, and suggest how they might (...)

We provide a semantic characterization for three axiomatic systems of increasing strength, showing how our approach can be modularly extended in order to get different levels of analysis (...)

Contrary to that orientation, this work seeks to establish the opposition of von Wright to Wittgenstein in relation to the question of whether ethics is an area where logic can legitimately extend. For Wittgenstein, logic deals with what is necessarily true. On the basis of this characterization of logic, Wittgenstein thinks that logic cannot legitimately help to capture ethics for the reason that the (...)

    Some sacrifices—like giving a kidney or heroically dashing into a burning building—are supererogatory: they are good deeds beyond the call of duty. But if such deeds are really so good, philosophers ask, why shouldn’t morality just require them? The standard answer is that morality recognizes a special role for the pursuit of self-interest, so that everyone may treat themselves as if they were uniquely important. This idea, however, cannot be reconciled with the compelling picture of morality as impartial—the view that (...)

This conception aligns with the functionalist approach to desire and the standard account of desire's role in explaining action. According to a second influential approach, however, desire is first and foremost an evaluation: desiring is representing something as good. After all, we seem to desire things under the guise of the good. Which understanding of desire is more accurate? Is the guise (...)

    The semantics for a deontic action logic based on Boolean algebra is extended with an interpretation of action expressions in terms of sets of alternative actions, intended as a way to model choice. This results in a non-classical interpretation of action expressions, while sentences not in the scope of deontic operators are kept classical. A deontic structure based on Simons’ supercover semantics is used to interpret permission and obligation. It is argued that these constructions provide ways to handle various problems (...)

    Este texto tem como objetivo apresentar a principal motivação filosófica para se defender uma teoria causal da memória, que é explicar como pode um evento que se deu no passado estar relacionado a uma experiência mnêmica que se dá no presente. Para tanto, iniciaremos apresentando a noção de memória de maneira informal e geral, para depois apresentar elementos mais detalhados. Finalizamos apresentando uma teoria causal da memória que se beneficia da noção de veritação (truthmaking).

  • Tragedy and the constancy of norms: towards an Anscombian conception of ‘ought’.Kristina Gehrman - 2019 - Philosophical Studies 176 (11):3077-3097.
    This paper presents an Anscombian alternative to the traditional deontic conception of ought. According to the Anscombian conception of ought developed here, ought is general as opposed to ‘peculiarly moral’, norm-referring instead of law- or obligation-referring, and ‘heroic’ in the sense that it does not presuppose that individuals can do or be as they ought. Its connection to matters of fact can, moreover, be clearly stated. In the first part of the paper, I describe some significant logical characteristics of this (...)

  • Enriching Deontic Logic.Ilaria Canavotto & Alessandro Giordani - 2018 - Journal of Logic and Computation 1:1-23.
    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 the paradoxes (...)

  • Dissidio, stasis e società dipolari.Carlo Grassi - 2017 - Rivista di Estetica 65:120-142.
    Jean-François Lyotard s'interroga sulla forma delle organizzazioni sociali e ne identifica la problematica principale nell'eterogeneità che esse veicolano tra i differenti regimi di frasi: si sofferma, in particolare, sull'incompatibilità tra il regime della conoscenza e quello della libertà. A partire da tale riflessione, l'articolo esamina come le società attuali, multiculturali e globalizzate, siano chiamate oggi a compiere una scelta: abbracciare la sintesi dell'eterogeneo oppure rispettare e far rispettare la presenza inevitabile del dissidio. Nella prima occorrenza si corre il rischio di (...)

  • Anderson’s Restriction of Deontic Modalities to Contingent Propositions.Matteo Pascucci - 2017 - Theoria 83 (4):440-470.
    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 (...)
