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)

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 being the (...) theses of our logic and (2) facts from the ontology of action whose relevance for the systems of norms we postulate.

ZI is intended to be a logic which provides a formal account for describing two kinds of (...) process change: the change from one state of the process to its other state (e.g., transmitting or absorbing energy with greater or less than the usual intensity) and the perishing of the process (e.g., cessation of the energetic activity of the sun).

The paper tackles two problems. The first one is to grasp the real meaning of Jerzy Kalinowski’s theory of normative sentences. His formal system K 1 is a simple logic formulated in a very limited language . While presenting it Kalinowski formulated a few interesting philosophical remarks on norms and actions. He did not, however, possess the tools to formalise them fully. We propose a formulation of Kalinowski’s ideas with the use of a set-theoretical frame similar to the one presented (...) by Krister Segerberg in his A Deontic Logic of Action. At the same time we enrich the language used by Kalinowski with more operators on actions and present an adequate axiomatisation of the resulting system. That allows us to disclose some unrevealed aspects of Kalinowski’s theory. The most important one is a relation between acts which we call moral indiscernibility. Our second problem is a proper understanding of moral indiscernibility. We show how a repertoire of agent’s actions, defined with the use of simple observable elements of actions, can be filtrated by the relation of moral indiscernibility. That allows us to understand the consequences of Kalinowski’s claim that not doing something good is always bad. (shrink)

ABOUT THE PUTTING NAMES TO OBJECTS, I.E. HOW TADEUSZ KOTARBIjSKI TEACHES UNDERSTAND STANISkAW LE3NIEWSKI’S ONTOLOGY S u m m a r y This article presents an attempt to fund Ontology of Stanis;aw Lemniewski on a simple theory with one primitive relation “being denoted by”. Developed theory shows that to the linguistic model of the Ontology can belong only such general names that in their extensions have at least two objects (references) denoted by individual names.

The main purpose of this paper was the trial to answer the question if norms can function as premises or conclusions in logical inferences. According to definition of logical inference, the parts of its may be only sentences (in indicative mood) which are true or false. The logic, which accepts that norms are the true and false propositions, can be named the Logic of Norms. Otherwise the logic, which reject that norms are true and false propositions, we name Deontic Logic. (...) The last one, in order to use the logical inference, changes each of norms N into normative sentences: W exists\' or W exists for the sake of set of norms\'. The normative sentences are sentences in indicative mood and thereby are true or false. The whole consideration about two types aforementioned logic is preceded by some remarks about variety of the meanings of the word \'norm\', the linguistic structures of norm and the views of the truth value of norms.

In the first systems of deontic logic obligatoriness, prohibitiveness and permissibility were features of actions. It was a very natural choice, corresponding to the way in which these concepts were used not only in natural language but also in Law and Ethics. It's well known that contemporary systems of deontic logics do not deal with actions any more. They are simply deontic logics of propositions providing for deontic qualification of states of affairs. Such an approach, although might be useful for (...) instance in Computer Science (especially in security applications, where there is a need of expressing that a certain state of machine is, say, permitted and the other is forbidden), is inadequate for modeling norms of Law and Ethics (and possibly norms of many other fields). In this paper the Simple Theory of Norms and Actions (in short: Setna) is proposed. It is inspired by the first deontic logics, i.e. it's deontic operators take names of actions as their arguments. Additionally this theory has as its part a theory of actions which has not been taken into account in deontic logic until now. Enriching deontic theory with a theory of action gives an account for expressing dependencies which hold between the deontic properties and some other properties of actions. For instance Setna states that two actions that cannot be carried out simultaneously in the same situation should not be both regulated as obligatory-an agent would not be able to follow such a law.

The paper offers a logical characterisation of multi-step actions in the context of deontic notions of obligation, permission and prohibition. Deontic notions for sequentially composed actions are founded on deontic notions for one-step actions. The present work includes a formal study of situations where execution of a multi-step action has been unsuccessful and provides normative analysis of such actions.

The paper tackles the problem of the relation between rights and obligations. Two examples of situations in which such a relation occurs are discussed. One concerns the abortion regulations in Polish law, the other one—a clash between freedom of expression and freedom of enterprise occurring in the context of discrimination. The examples are analysed and formalised using labelled transition systems in the \ framework. Rights are introduced to the system as procedures allowing for their fulfilment. Obligations are based on the (...) requirement of cooperation in the realisation of the goals of the agent that has a right. If the right of an agent cannot be fulfilled without an action of another agent, then that action is obligatory for that agent. If there are many potential contributors who are individually allowed to refuse, then the last of them is obliged to help when all the others have already refused. By means of formalisation this account of the relation under consideration is precisely expressed and shown consistent. (shrink)

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 (...) guideline how to build a deontic action logic which satisfies the desired properties. (shrink)

This paper tackles the problem of inference in normative systems where norms concerning actions and states of affairs appear together. A deontic logic of actions and states is proposed as a solution. It is made up of two independent deontic logics, namely a deontic logic of action and a deontic logic of states, interlinked by bridging definitions. It is shown at a language and a model level how an agent should look for norms to follow in a concrete situation. It (...) is pointed out that such specific norms are obtained by finding the most specific obligation and the most general prohibition. They are to be derived from all norms applicable to the situation by using the principles of the logic presented in this paper. (shrink)

Trivalence is quite natural for deontic action logic, where actions are treated as good, neutral or bad.We present the ideas of trivalent deontic logic after J. Kalinowski and its realisation in a 3-valued logic of M. Fisher and two systems designed by the authors of the paper: a 4-valued logic inspired by N. Belnap’s logic of truth and information and a 3-valued logic based on nondeterministic matrices. Moreover, we combine Kalinowski’s idea of trivalence with deontic action logic based on boolean (...) algebra. (shrink)

In the paper we provide an overview of issues related to the models used in the research on the logic of norms and actions. We present two models of the variability of the world: temporal (acyclic) and atemporal (cyclic). In the first one the past is always clearly defined, and the future is potentially “branched”. The second type of model allows for a return to the situation that took place. Next we describe different approaches towards agency modeling. We present the (...) most important paradigms, including the logic of actions, where actions are interpreted as transitions between the situations and STIT logic, which states only the responsibility of the agent for particular states of affairs. We discuss questions of determinism and indeterminism of actions, identification of basic actions and operations and the issue of identity. The final part of the paper is devoted to deontic categories. In particular, the applicability of the concepts of strong and weak permission and prohibition in different situational contexts, and their relationship to the two concepts of obligation: abstract and derived.

We investigate a speci c model of knowledge and beliefs and their dynamics. The model is inspired by public announcement logic and the approach to puzzles concerning knowledge using that logic. In the model epistemic considerations are based on ontology. The main notion that constitutes a bridge between these two disciplines is the notion of epistemic capacities. Within the model we study scenarios in which agents can receive false announcements and can have incomplete or improper views about other agent's epistemic (...) capacities. Moreover, we try to express the description of problem speci cation using the tools from applied ontology { RDF format for information and the Protege editor. (shrink)

In the paper we discuss different intuitions about the properties of obligatory actions in the framework of deontic action logic based on boolean algebra. Two notions of obligation are distinguished–abstract and processed obligation. We introduce them formally into the system of deontic logic of actions and investigate their properties and mutual relations.

This paper studies some normative relations that hold between actions, their preconditions and their effects, with particular attention to connecting what are often called ‘ought to be’ norms with ‘ought to do’ norms. We use a formal model based on a form of transition system called a ‘coloured labelled transition system’ (coloured LTS) introduced in a series of papers by Sergot and Craven. Those works have variously presented a formalism (an ‘action language’) nC+ for defining and computing with a (coloured) (...) LTS, and another, separate formalism, a modal language interpreted on a (coloured) LTS used to express its properties. We consolidate these two strands. Instead of specifying the obligatory and prohibited states and transitions as part of the construction of a coloured LTS as in nC+, we represent norms in the modal language and use those to construct a coloured LTS from a given regular (uncoloured) one. We also show how connections between norms on states and norms on transitions previously treated as fixed constraints of a coloured LTS can instead be defined within the modal language used for representing norms.

Robert Alexy develops his influential theory of legal reasoning exploring the nature of legal argumentation and its relation to practical reasoning. In doing so he sheds light on fundamental questions of law and rationality, which are as crucial to practising lawyers and law students as they are to scholars of legal theory.

At the heart of this book is the age-old question of how law and morality are related. The legal positivist, insisting on the separation of the two, explicates the concept of law independently of morality. The author challenges this view, arguing that there are, first, conceptually necessary connections between law and morality and, second, normative reasons for including moral elements in the concept of law. While the conceptual argument alone is too limited to establish a sufficiently strong connection between law (...) and morality, and the normative argument alone fails to address the nature of law, the two arguments together support a nonpositivistic concept of law, toppling legal positivism qua comprehensive theory of law.

This book analyses the general structure of constitutional rights reasoning under the German Basic Law. It deals with a wide range of problems common to all systems of constitutional rights review. In an extended introduction the translator argues for its applicability to the British Constitution, with particular reference to the Human Rights Act 1998.

Robert Batterman examines a form of scientific reasoning called asymptotic reasoning, arguing that it has important consequences for our understanding of the scientific process as a whole. He maintains that asymptotic reasoning is essential for explaining what physicists call universal behavior. With clarity and rigor, he simplifies complex questions about universal behavior, demonstrating a profound understanding of the underlying structures that ground them. This book introduces a valuable new method that is certain to fill explanatory gaps across disciplines.

Robert Stalnaker opposes the traditional view that knowledge of one's own current thoughts and feelings is the unproblematic foundation for all knowledge. He argues that we can understand our knowledge of our thoughts and feelings only by viewing ourselves from the outside, by seeing our inner lives as features of the world as it is in itself.

Where does the mind begin and end? Most philosophers and cognitive scientists take the view that the mind is bounded by the skull or skin of the individual. Robert Wilson, in this provocative and challenging 2004 book, provides the foundations for the view that the mind extends beyond the boundary of the individual. The approach adopted offers a unique blend of traditional philosophical analysis, cognitive science, and the history of psychology and the human sciences. The companion volume, Genes and (...) the Agents of Life, explores the theme in the biological sciences. Written with verve and clarity, this ambitious book will appeal to a broad swathe of professionals and students in philosophy, psychology, cognitive science, and the history of the behavioural and human sciences.

In Overdoing Democracy, Robert B. Talisse turns the popular adage "the cure for democracy's ills is more democracy" on its head. Indeed, he argues, the widely recognized, crisis-level polarization within contemporary democracy stems from the tendency among citizens to overdo democracy. When we make everything--even where we shop, the teams we cheer for, and the coffee we drink--about our politics, we weaken our bonds to one another, and work against the fundamental goals of democracy. Talisse advocates civic friendship built (...) around shared endeavors that we must undertake with fellow citizens who do not necessarily share our political affinities as the best way we can obtain a healthier, more sustainable democracy.

This volume collects thirty years worth of articles on the emotions written by the distinguished philosopher Robert Solomon. Solomon's thesis is that we are significantly responsible for our emotions, which are evaluative judgments that in effect we choose. This is the first of several volumes that document work in the emotions.

There are two basic views concerning the relationship between constitutional rights and proportionality analysis. The first maintains that there exists a necessary connection between constitutional rights and proportionality, the second argues that the question of whether constitutional rights and proportionality are connected depends on what the framers of the constitution have actually decided, that is, on positive law. The first thesis may be termed ‘necessity thesis’, the second ‘contingency thesis’. According to the necessity thesis, the legitimacy of proportionality analysis is (...) a question of the nature of constitutional rights, according to the contingency thesis, it is a question of interpretation. The article defends the necessity thesis. | A previous version of this article was published in Chinese Yearbook of Constitutional Law, Vol. 2010, 221–235. (shrink)

The author's thesis is that there is a conceptually necessary connection between law and morality which means legal positivism must fail as a comprehensive theory. The substantiation of this thesis takes place within a conceptual framework which shows that there are at least 64 theses to be distinguished, concerning the relationship of law and morality. The basis for the author's argument in favour of a necessary connection, is formed by the thesis that individual legal norms and decisions as well as (...) whole legal systems necessarily make a claim to correctness. The explication of this claim within the frame of discourse theory shows that the law has a conceptually necessary, ideal dimension, which connects law with a procedural, universalistic morality.

This book articulates and defends Fregean realism, a theory of properties based on Frege's insight that properties are not objects, but rather the satisfaction conditions of predicates. Robert Trueman argues that this approach is the key not only to dissolving a host of longstanding metaphysical puzzles, such as Bradley's Regress and the Problem of Universals, but also to understanding the relationship between states of affairs, propositions, and the truth conditions of sentences. Fregean realism, Trueman suggests, ultimately leads to a (...) version of the identity theory of truth, the theory that true propositions are identical to obtaining states of affairs. In other words, the identity theory collapses the gap between mind and world. This book will be of interest to anyone working in logic, metaphysics, the philosophy of language or the philosophy of mind. (shrink)

Philosophy is general and systematic reflection about what there is, what ought to be done or is good, and how knowledge about both is possible. Legal philosophy raises these questions with respect to the law. In so doing, legal philosophy is engaged in reasoning about the nature of law. The arguments addressed to the question of the nature of law revolve around three problems. The first problem addresses the question: In what kinds of entities does the law consist, and how (...) are these entities connected such that they form the overarching entity we call “law”? The answer is that law consists of norms as meaning contents which form a normative system. The second problem addresses the question of how norms as meaning contents are connected with the real world. This connection can be grasped by means of the concepts of authoritative issuance and social efficacy. The latter includes the concept of coercion or force. The third problem addresses the correctness or legitimacy of law, and, by this, the relationship between law and morality. To ask about the nature of law is to ask about necessary relations between the concepts of normative meaning, authoritative issuance as well as social efficacy, and correctness of content. (shrink)

We live our lives through our emotions, writes Robert Solomon, and it is our emotions that give our lives meaning. What interests or fascinates us, who we love, what angers us, what moves us, what bores us--all of this defines us, gives us character, constitutes who we are. In True to Our Feelings, Solomon illuminates the rich life of the emotions--why we don't really understand them, what they really are, and how they make us human and give meaning to (...) life. Emotions have recently become a highly fashionable area of research in the sciences, with brain imaging uncovering valuable clues as to how we experience our feelings. But while Solomon provides a guide to this cutting-edge research, as well as to what others--philosophers and psychologists--have said on the subject, he also emphasizes the personal and ethical character of our emotions. He shows that emotions are not something that happen to us, nor are they irrational in the literal sense--rather, they are judgements we make about the world, and they are strategies for living in it. Fear, anger, love, guilt, jealousy, compassion--they are all essential to our values, to living happily, healthily, and well. Solomon highlights some of the dramatic ways that emotions fit into our ethics and our sense of the good life, how we can make our emotional lives more coherent with our values and be more "true to our feelings" and cultivate emotional integrity. The story of our lives is the story of our passions. We fall in love, we are gripped by scientific curiosity and religious fervor, we fear death and grieve for others, we humble ourselves in envy, jealousy, and resentment. In this remarkable book, Robert Solomon shares his fascination with the emotions and illuminates our passions in an exciting new way. (shrink)

Presenting the history of space-time physics, from Newton to Einstein, as a philosophical development DiSalle reflects our increasing understanding of the connections between ideas of space and time and our physical knowledge. He suggests that philosophy's greatest impact on physics has come about, less by the influence of philosophical hypotheses, than by the philosophical analysis of concepts of space, time and motion, and the roles they play in our assumptions about physical objects and physical measurements. This way of thinking leads (...) to interpretations of the work of Newton and Einstein and the connections between them. It also offers ways of looking at old questions about a priori knowledge, the physical interpretation of mathematics, and the nature of conceptual change. Understanding Space-Time will interest readers in philosophy, history and philosophy of science, and physics, as well as readers interested in the relations between physics and philosophy. (shrink)

Robert Stalnaker is an actualist who holds that merely possible worlds are uninstantiated properties that might have been instantiated. Stalnaker also holds that there are no metaphysically impossible worlds: uninstantiated properties that couldn't have been instantiated. These views motivate Stalnaker's "two dimensional" account of the necessary a posteriori on which there is no single proposition that is both necessary and a posteriori. For a (metaphysically) necessary proposition is true in all (metaphysically) possible worlds. If there were necessary a posteriori (...) propositions, that would mean that there were propositions true in all possible worlds but which could only be known to be true by acquiring empirical evidence. Consider such a purported proposition P. The role of empirical evidence for establishing P's truth would have to be to rule out worlds in which P is false. If there were no such worlds to be ruled out, we would not require evidence for P. But by hypothesis, P is necessary and so true in all metaphysically possible worlds. And on Stalnaker's view, the metaphysically possible worlds are all the worlds there are. So there can be no proposition that is true in all possible worlds, but that we require evidence to know. In this way, the motivation for Stalnaker's two dimensional account of the necessary a posteriori rests on his denying that there are metaphysically impossible Worlds. I argue that given his view of what possible worlds are, Stalnaker has no principled reason for denying that there are metaphysically impossible worlds. If I am right, this undercuts Stalnaker's motivation for his two dimensional account of the necessary a posteriori. (shrink)

Contemporary discussions about practical reason or practical rationality invoke four competing views which can be named as follows by reference to their historical models: Aristotelian, Hobbesian, Kantian and Nietzschean. The subject-matter of this article is a defence of the Kantian conception of practical rationality in the interpretation of discourse theory. At the heart, lies the justification and the application of the rules of discourse. An argument consisting of three parts is pre sented to justify the rules of discourse. The three (...) parts are as follows: a transcen dental-pragmatic argument; an argument which takes account of the maximisation of individual utility and an empirical premise about an interest in correctness. Within the framework of the problem of application, the article outlines a justification of human rights and of the basic institutions of the democratic constitutional state on the basis of discourse theory.

In this significant contribution to Hegel scholarship, Robert Williams develops the most comprehensive account to date of Hegel's concept of recognition. Fichte introduced the concept of recognition as a presupposition of both Rousseau's social contract and Kant's ethics. Williams shows that Hegel appropriated the concept of recognition as the general pattern of his concept of ethical life, breaking with natural law theory yet incorporating the Aristotelian view that rights and virtues are possible only within a certain kind of community. (...) He explores Hegel's intersubjective concept of spirit as the product of affirmative mutual recognition and his conception of recognition as the right to have rights. Examining Hegel's Jena manuscripts, his _Philosophy of Right_, the _Phenomenology of Spirit_, and other works, Williams shows how the concept of recognition shapes and illumines Hegel's understandings of crime and punishment, morality, the family, the state, sovereignty, international relations, and war. A concluding chapter on the reception and reworking of the concept of recognition by contemporary thinkers including Derrida, Levinas, and Deleuze demonstrates Hegel's continuing centrality to the philosophical concerns of our age.

[Robert Stalnaker] Saul Kripke made a convincing case that there are necessary truths that are knowable only a posteriori as well as contingent truths that are knowable a priori. A number of philosophers have used a two-dimensional model semantic apparatus to represent and clarify the phenomena that Kripke pointed to. According to this analysis, statements have truth-conditions in two different ways depending on whether one considers a possible world 'as actual' or 'as counterfactual' in determining the truth-value of the (...) statement relative to that possible world. There are no necessary a posteriori or contingent a priori propositions: rather, contingent a priori and necessary a posteriori statements are statements that are necessary when evaluated one way, and contingent when evaluated the other way. This paper distinguishes two ways that the two-dimensional framework can be interpreted, and argues that one of them gives the better account of what it means to 'consider a world as actual', but that it provides no support for any notion of purely conceptual a priori truth. /// [Thomas Baldwin] Two-dimensional possible world semantic theory suggests that Kripke's examples of the necessary a posteriori and contingent a priori should be handled by interpreting names as implicitly indexical. Like Stalnaker, I reject this account of names and accept that Kripke's examples have to be accommodated within a metasemantic theory. But whereas Stalnaker maintains that a metasemantic approach undermines the conception of a priori truth, I argue that it offers the opportunity to develop a conception of the a priori aspect of stipulations, conceived as linguistic performances. The resulting position accommodates Kripke's examples in a way which is both intrinsically plausible and fits with Kripke's actual discussion of them. (shrink)

Human beings, like other organisms, are the products of evolution. Like other organisms, we exhibit traits that are the product of natural selection. Our psychological capacities are evolved traits as much as are our gait and posture. This much few would dispute. Evolutionary psychology goes further than this, claiming that our psychological traits -- including a wide variety of traits, from mate preference and jealousy to language and reason -- can be understood as specific adaptations to ancestral Pleistocene conditions. In (...) Evolutionary Psychology as Maladapted Psychology, Robert Richardson takes a critical look at evolutionary psychology by subjecting its ambitious and controversial claims to the same sorts of methodological and evidential constraints that are broadly accepted within evolutionary biology. The claims of evolutionary psychology may pass muster as psychology; but what are their evolutionary credentials? Richardson considers three ways adaptive hypotheses can be evaluated, using examples from the biological literature to illustrate what sorts of evidence and methodology would be necessary to establish specific evolutionary and adaptive explanations of human psychological traits. He shows that existing explanations within evolutionary psychology fall woefully short of accepted biological standards. The theories offered by evolutionary psychologists may identify traits that are, or were, beneficial to humans. But gauged by biological standards, there is inadequate evidence: evolutionary psychologists are largely silent on the evolutionary evidence relevant to assessing their claims, including such matters as variation in ancestral populations, heritability, and the advantage offered to our ancestors. As evolutionary claims they are unsubstantiated. Evolutionary psychology, Richardson concludes, may offer a program of research, but it lacks the kind of evidence that is generally expected within evolutionary biology. It is speculation rather than sound science -- and we should treat its claims with skepticism. (shrink)

Why democracy? Most often this question is met with an appeal to some decidedly moral value, such as equality, liberty, dignity or even peace. But in contemporary democratic societies, there is deep disagreement and conflict about the precise nature and relative worth of these values. And when democracy votes, some of those who lose will see the prevailing outcome as not merely disappointing, but morally intolerable. How should citizens react when confronted with a democratic result that they regard as intolerable? (...) Should they revolt, or instead pursue democratic means of social change? In this book, Robert Talisse argues that each of us has reasons to uphold democracy - even when it makes serious moral errors - and that these reasons are rooted in our most fundamental epistemic commitments. His original and compelling study will be of interest to a wide range of readers in political philosophy and political theory. (shrink)
