The book provides a historical and systematic exposition of the semantic theory of truth formulated by Alfred Tarski in the 1930s. This theory became famous very soon and inspired logicians and philosophers. It has two different, but interconnected aspects: formal-logical and philosophical. The book deals with both, but it is intended mostly as a philosophical monograph. It explains Tarski’s motivation and presents discussions about his ideas as well as points out various applications of the semantic theory of truth to philosophical (...) problems. (shrink)

The basic bearer of responsibility is individuals, because that isall there are – nothing else can literally be the bearer of fullresponsibility. Claims about group responsibility therefore needanalysis. This would be impossible if all actions must be understoodas ones that could be performed whether or not anyone else exists.Individuals often act by virtue of membership in certain groups;often such membership bears a causal role in our behavior, andsometimes people act deliberately in order to promote the prospectsof members of a given (...) group. Nevertheless, it is rational to awardproportionally to individual contributions to those actions andindividual shares in the production of the consequences of thoseactions. (shrink)

The paper presents an ethical analysis and constructive critique of the current practice of AI ethics. It identifies conceptual substantive and procedural challenges and it outlines strategies to address them. The strategies include countering the hype and understanding AI as ubiquitous infrastructure including neglected issues of ethics and justice such as structural background injustices into the scope of AI ethics and making the procedures and fora of AI ethics more inclusive and better informed with regard to philosophical ethics. These measures (...) integrate the perspective of AI justice into AI ethics, strengthening its capacity to provide comprehensive normative orientation and guidance for the development and use of AI that actually improves human lives and living together.

Hypothetico-deductive (H-D) confirmation builds on the idea that confirming evidence consists of successful predictions that deductively follow from the hypothesis under test. This article reviews scope, history and recent development of the venerable H-D account: First, we motivate the approach and clarify its relationship to Bayesian confirmation theory. Second, we explain and discuss the tacking paradoxes which exploit the fact that H-D confirmation gives no account of evidential relevance. Third, we review several recent proposals that aim at a sounder and (...) more comprehensive formulation of H-D confirmation. Finally, we conclude that the reputation of hypothetico-deductive confirmation as outdated and hopeless is undeserved: not only can the technical problems be addressed satisfactorily, the hypothetico-deductive method is also highly relevant for scientific practice.

This book provides the reader with an analysis of backward causation. The notion of backward causation faces many different paradoxes that threaten to make the notion inconsistent or incoherent. The book denies that these pose a real threat. It developed a theory of causation according to which the orientation of causation is not dependent on the direction of time. In this process it takes issues with David Lewis' contrafactual analysis of causation, and denies that the direction of time is determined (...) by irreversible processes . Likewise the book argues that the conceptual possibility of backward causation requires that the future is just as real as the past and present. Finally the book considers what the physical processes may look like if backward causation not only a a conceptual possibility but also a physical possibility. The conclusion is that no normal matter can possibly participate in backward causal processes. Instead objects moving backwards in time seem to posses negative mass and energy, a kind of objects that would be different from both ordinary objects and hypothetical tachyons. (shrink)

This paper develops a probabilistic reconstruction of the No Miracles Argument in the debate between scientific realists and anti-realists. The goal of the paper is to clarify and to sharpen the NMA by means of a probabilistic formalization. In particular, we demonstrate that the persuasive force of the NMA depends on the particular disciplinary context where it is applied, and the stability of theories in that discipline. Assessments and critiques of "the" NMA, without reference to a particular context, are misleading (...) and should be relinquished. This result has repercussions for recent anti-realist arguments, such as the claim that the NMA commits the base rate fallacy. It also helps to explain the persistent disagreement between realists and anti-realists. (shrink)

Is knowledge-how, or “practical” knowledge, a species of knowledge-that, or “theoretical” knowledge? There is no comfortable position to take in the debate around this question. On the one hand, there are counterexamples against the anti-intellectualist thesis that practical knowledge is best analysed as an ability. They show that having an ability to ϕ is not necessary for knowing how to ϕ. On the other hand, the intellectualist analysis of practical knowledge as a subspecies of theoretical knowledge is threatened by its (...) own set of counterexamples, which convincingly establish that practical knowledge lacks many of the typical characteristics of theoretical knowledge. Most strikingly it does not even appear to require a belief. In this paper, I develop an account of practical knowledge that avoids these counterexamples. It also manages to preserve both the status of such knowledge as a cognitive achievement and its apparently close conceptual relation to abilities. I start with the counterexamples against the necessity of abilities for practical knowledge and show that they fail because they underestimate the cognitive demands of attempts. I then make use of the logic of dispositions to bridge the gap that counterexamples against the necessity of abilities for practical knowledge open. It is argued that, instead of the ability to ϕ, it is a specific disposition to have the ability to ϕ that constitutes practical knowledge about ϕ. The resulting theory is an anti-intellectualist position that preserves essential intellectualist motivations and thus should be satisfactory for proponents of both views. (shrink)

Of all the attitudes and theories associated with or identified as "pacifism," only the doctrine that everyone ought not to resist violence with force is of philosophical interest, And it is logically incoherent. Pacifism's popularity rests on confusions about what the doctrine really is. If we have rights, We have the right to prevent infringements upon them. We have the right to use force to protect our rights, And in the degree necessary to accomplish that end. (staff).

Niels Bohr and Philosophy of Physics: Twenty-First Century Perspectives examines the work, influences and legacy of the Nobel Prize physicist and philosopher of experiment Niels Bohr. While covering Bohr's groundbreaking contribution to quantum mechanics, this collection reveals the philosophers who influenced his work. Linking him to the pragmatist C.I. Lewis and the Danish philosopher Harald Høffding, it draws strong similarities between Bohr's philosophy and the Kantian way of thinking. Addressing the importance of Bohr's views of classical concepts, it discusses how (...) his interpretation of quantum mechanics now compares with a variety of issues that have arisen only since his lifetime, including decoherence and other non-collapse arguments. Balancing historical themes with contemporary ideas, Niels Bohrs and Philosophy of Physics reveals Bohr's on-going contribution to the philosophy of science and confirms his place in the history of philosophy.

Professional autonomy is often described as a claim of professionalsthat has to serve primarily their own interests. However, it can also beseen as an element of a professional ideal that can function as astandard for professional, i.e. medical practice. This normativeunderstanding of the medical profession and professional autonomy facesthree threats today. 1) Internal erosion of professional autonomy due toa lack of internal quality control by the medical profession; 2)the increasing upward pressure on health care expenses that calls for ahealth care (...) policy that could imply limitations for the professionalautonomy of physicians; 3) a distorted understanding of theprofession as being based on a formal type of knowledge and relatedtechnology, in which other normative dimensions of medical practice areneglected and which frustrates meaningful communication betweenphysicians and patients. To answer these threats a normative structureanalysis of medical practice is presented, that indicates whichprinciples and norms are constitutive for medical practice. It isconcluded that professional autonomy, normatively understood, should bemaintained to avoid the lure of the technological imperative and toprotect patients against third parties' pressure to undertreatment.However, this professional autonomy can only be maintained if members ofthe profession subject their activities and decisions to a criticalevaluation by other members of the profession and by patients and ifthey continue to critically reflect on the values that regulate today'smedicine.

The paper offers a normative analysis of the new Loss & Damage Fund supporting vulnerable countries grappling with climate change-related harms. This fund is primarily financed by affluent nations, often identified as historical polluters. However, the perspective of relational egalitarianism highlights persistent structural injustices in the background of the fund. Addressing them necessitates conceptualizing the fund not merely as an act of cooperative solidarity but as compensation for the consequences of historical and ongoing structural injustices. Properly conceived, the fund manages (...) adverse climate effects and simultaneously tackles their underlying root causes, including the unjust distribution of advantages and power. (shrink)

According to influential accounts of scientific method, such as critical rationalism, scientific knowledge grows by repeatedly testing our best hypotheses. But despite the popularity of hypothesis tests in statistical inference and science in general, their philosophical foundations remain shaky. In particular, the interpretation of non-significant results—those that do not reject the tested hypothesis—poses a major philosophical challenge. To what extent do they corroborate the tested hypothesis, or provide a reason to accept it? Popper sought for measures of corroboration that could (...) adequately answer this question. According to Popper, corroboration is different from probability-raising, and grounded in the predictive success and testability of a hypothesis. As such, corroboration becomes an indicator of the scientific value of a hypothesis and guides our practical preferences over hypotheses that have been subjected to severe tests. This article proves two impossibility results for corroboration measures based on statistical relevance. The generality of these results shows that Popper’s qualitative characterization of corroboration must be misguided. I explore what a more promising and scientifically useful concept of corroboration could look like. (shrink)

Clinicians and administrators have a professional obligation to contribute (OTC) to improvement of healthcare quality. At the same time, participation in embedded research poses risks to healthcare institutions. Disclosure of an institution’s sensitive information could endanger relationships with patients and undermine its reputation. The existing ethical framework (EF) for learning healthcare systems (LHSs) does not address the conflict between the OTC and institutional interests. Ethical guidance and policy regulation are needed to create a safe environment for embedded research. In this (...) article we analyse the EF for LHSs and the concept of professionalism. We suggest that the EF should be supplemented with an obligation to protect provider’s legitimate interests. We define legitimate interests as those that enable providers to discharge their primary duties. We argue that both the OTC and the obligation to protect legitimate interests are grounded in the concept of medical professionalism and can be understood as a matter of contract between a democratic society and medical professionals. The proposed supplemented EF can be implemented into a regulatory system in three different ways: theself-regulating: where providers decide themselves how to balance the ethical claims, the centralised: where a governmental institution decides the right balance between providers’ interests and interests of a health system; and themediating: where medical professionals, the state and patients negotiate their interests. Our article contributes to the discussion on ethical relevance of providers’ interests and the regulatory model for weighing opposite interests in LHSs. (shrink)

We have long been accustomed to thinking of democracy as a major selling point of Western institutions. That a set of political institutions should be democratic is widely regarded as the sine qua non of their legitimacy. So widespread is this belief that even those whose institutions do not look very democratic to us nevertheless insist on proclaiming them to be such. Meanwhile, an adulatory attitude toward democracy has arisen in many quarters, and many theorists have taken up anew the (...) idea that if democracy is the way to go in political institutions, then it must also be the way to go in “other” areas, notably in economic and social institutions. So there has arisen a call for “economic democracy” — which is taken to mean, especially, that the “means of production” should be managed by their constituent workers in concert rather than by some few who own, or act for the owners of, those enterprises. Robert Dahl, in his influential Preface to Economic Democracy, sums it up nicely when he proclaims a “stronger justification” for worker participation: “ If democracy is justified in governing the state, then it must also be justified in governing economic enterprises; and to say that it is not justified in governing economic enterprises is to imply that it is not justified in governing the state.”.

To what extent does the design of statistical experiments, in particular sequential trials, affect their interpretation? Should postexperimental decisions depend on the observed data alone, or should they account for the used stopping rule? Bayesians and frequentists are apparently deadlocked in their controversy over these questions. To resolve the deadlock, I suggest a three‐part strategy that combines conceptual, methodological, and decision‐theoretic arguments. This approach maintains the pre‐experimental relevance of experimental design and stopping rules but vindicates their evidential, postexperimental irrelevance. †To (...) contact the author, please write to: Tilburg Center for Logic and Philosophy of Science, Tilburg University, P.O.

In recent years, the use of historical cases in philosophy of science has become a proper topic of reflection. In this article I will contribute to this research by means of a discussion of one very famous example of case-based philosophy of science, namely the debate on the London & London model of superconductivity between Cartwright, Suárez and Shomar on the one hand, and French, Ladyman, Bueno and Da Costa on the other. This debate has been going on for years, (...) without any satisfactory resolution. I will argue here that this is because both sides impose on the historical case a particular philosophical conception of scientific representation that does not do justice to the historical facts. Both sides assume, more specifically, that the case concerns the discovery of a representational connection between a given experimental insight – the Meissner effect – and the diamagnetic meaning of London and London’s new equations of superconductivity. I will show, however, that at the time of the Londons’ publication, neither the experimental insight nor the meaning of the new equations was established: both were open for discussion and they were stabilized only later. On the basis of this historical discussion, I will then propose an alternative approach to the case study: the case should not be seen as a site of confrontation between pre-existing philosophical accounts, but rather as a way to historically elaborate and develop philosophical concepts. I will then show how approaching the historical episode in this way suggests an alternative approach to the philosophical study of representation, according to which it involves the establishment, over time, of a stable connection between constellations of different elements that, through discussion and engagement with alternative views and approaches, come to constitute phenomenon and meaning.

The subject of this article is Modal-Epistemic Arithmetic (MEA), a theory introduced by Horsten to interpret Epistemic Arithmetic (EA), which in turn was introduced by Shapiro to interpret Heyting Arithmetic. I will show how to interpret MEA in EA such that one can prove that the interpretation of EA is MEA is faithful. Moreover, I will show that one can get rid of a particular Platonist assumption. Then I will discuss models for MEA in light of the problems of logical (...) omniscience and logical competence. Awareness models, impossible worlds models and syntactical models have been introduced to deal with the first problem. Certain conditions on the accessibility relations are needed to deal with the second problem. I go on to argue that those models are subject to the problem of quantifying in, for which I will provide a solution. (shrink)

Advances in biotechnology have enabled interventions in the human organism that promise to increase physical and intellectual perform over the 'normal' or 'natural' boundary, as well as make possible targeted changes in human experience. The author investigates ethical debates surrounding these issues with a particular focus on arguments that employ a normative concept of a person in order to establish that particular interventions are permissible or impermissible. He develops an integrated model that 'maps' of the concept of a human being, (...) thereby bringing the normative elements of the concept to the fore. Nevertheless, with a view to issues of risk and justice, the author argues that anthropological arguments are only one elements of a comprehensive ethics of enhancement. (shrink)

Are the political ideals of liberty and equality compatible? This question is of central and continuing importance in political philosophy, moral philosophy, and welfare economics. In this book, two distinguished philosophers take up the debate. Jan Narveson argues that a political ideal of negative liberty is incompatible with any substantive ideal of equality, while James P. Sterba argues that Narveson's own ideal of negative liberty is compatible, and in fact leads to the requirements of a substantive ideal of equality. Of (...) course, they cannot both be right. Thus, the details of their arguments about the political ideal of negative liberty and its requirements will determine which of them is right. Engagingly and accessibly written, their debate will be of value to all who are interested in the central issue of what are the practical requirements of a political ideal of liberty. (shrink)

According to a common opinion, the word ‘semantics’ , derived from the Greek word semantikos , appeared for the first time, at least in modern times, in the book Essai de semantique, science de significations by M. J. A. Bréal . However, Quine says in his lectures on Carnap:As used by C. S. Peirce, “semantic” is the study of the modes of denotation of signs: whether a sign denotes its object through causal or symptomatic connection, or through imagery, or through (...) arbitrary convention and so on. This sense of semantic, namely a theory of meaning, is used also in empirical philology: empirical semantic is the study of historical changes of meanings of words.1For Bréal, semantics was a branch of general linguistics. In particular, semantics was occupied with so-called lexical meaning and its changes through time. Thus, semantics in this sense belonged to what was called “the diachronic treatment of language”. This tradition is fairly alive in contemporary linguistic theory. Quine’s description of the word ‘semantic’ in Peirce corresponds, which Quine explicitly states, to its use in philology. However, some linguists ascribe a more theoretical role to lingustic semantics. Karl Bühler is an example. In his Sprachtheorie he says that a theory of semantic functions of language is a part of theory of language.2 This account is to be found also among philosophers. It is also rather obvious that Peirce did not limit his semantic only to empirical studies. Linguists also use the word ‘semasiology’ instead of ‘semantics’; Bühler proposed the term ‘sematology’ for a general theory of symbols. (shrink)

Critical realism claims to bring a significant improvement to social science, especially in comparison with empiricist and interpretive approaches. So far, however, it has fallen short of the high expectations it raises. Critical realist arguments are convincing on the philosophical or meta-theoretical level but the contributions of critical realism to social science in terms of research activities at the field level are less clear. Nonetheless, there is no way back. Moving forward requires that the practice of doing social scientific research (...) be no longer perceived as limited to the justification of specific knowledge claims but must be seen as an integral part of the cycle of scientific discovery.

A number of well-developed theories shed light on the question, under what circumstances our beliefs enjoy epistemic justification. Yet, comparatively little is known about epistemic defeat--when new information causes the loss of epistemic justification. This book proposes and defends a detailed account of epistemic defeaters. The main kinds of defeaters are analyzed in detail and integrated into a general framework that aims to explain how beliefs lose justification. It is argued that defeaters introduce incompatibilities into a noetic system and thereby (...) prompt a structured re-evaluation process that makes a justified reinstatement of the defeated belief impossible. The account is then applied to the topic of disagreement, where it is used in an argument for conciliationism, as well as a new explanation for higher-order defeat. Throughout the book, the notion of defeat is the center of attention, while a number of new issues are discussed at the intersections of defeat and justification. Specifically, new problems are raised for broadly internalist accounts of defeat, a fully descriptive reliabilist account of defeat is provided, and the case for normative defeat is revisited.

For the Critical Theory tradition of the Frankfurt School, rationalisation is a central concept that refers to the socio-cultural closure of capitalist modernity due to the proliferation of technical, ‘instrumental’ rationality at the expense of some form of political reason. This picture of rationalisation, however, hinges on a separation of technology and politics that is both empirically and philosophically problematic. This article aims to re-conceptualise the rationalisation thesis through a survey of research from science and technology studies and the conceptual (...) framework of Niklas Luhmann's systems theory. It argues that rationalisation indeed exhibits a logic of closure, namely the ‘operational closure’ of sociotechnical systems of measurement, but that this closure in fact produces the historical logics of technical reason and, paradoxically, also generates spaces of critical-political openness. This opens up the theoretical and practical opportunity of connecting the politically just to the technically efficient. (shrink)

We extend stit logic by adding a spatial dimension. This enables us to distinguish between powers and opportunities of agents. Powers are agent-specific and do not depend on an agent’s location. Opportunities do depend on locations, and are the same for every agent. The central idea is to define the real possibility to see to the truth of a condition in space and time as the combination of the power and the opportunity to do so. The focus on agent-relative powers (...) and space-relative opportunities firmly roots effectivity of an autonomous choice making agent in a space–time picture. Our space–time view will be classically Newtonian, since we will assume relativistic phenomena do not play a role in agentive effectivity. We show how our semantics naturally distinguishes between different kinds of histories; histories that reflect real possibilities and histories that reflect counterfactual possibilities. Furthermore, we discuss how the spatial picture sheds light on conceptual problems plaguing the central stit property of ‘independence of agency’. At several points in the article we will emphasise and defend the differences with Belnap’s theory of agency in relativistic branching space–times. (shrink)

This volume weaves together a variety of perspectives aimed at confronting a spectrum of ethico-political global challenges arising in the Anthropocene which affect the future of life on planet earth. In this book, the authors offer a multi-faceted approach to address the consequences of its imaginary and projective directions. The chapters span the disciplines of political economy, cybernetics, environmentalism, bio-science, psychoanalysis, bioacoustics, documentary film, installation art, geoperformativity, and glitch aesthetics. The first section attempts to flesh out new aspects of current (...) debates. Questions over the Capitaloscene are explored via conflations of class and climate, revisiting the eco-Marxist analysis of capitalism, and the financial system that thrives on debt. The second section explores the imaginary narratives that raise questions regarding non-human involvement. The third section addresses ’geoartisty,’ the counter artistic responses to the speculariztion of climate disasters, questioning eco-documentaries, and what a post-anthropocentric art might look like. The last section addresses the pedagogical response to the Anthropocene. (shrink)

Jeffrey Friedman broaches a number of criticisms of Libertarianism as a conceptual basis for opposing the extensive modern welfare state, examining several variants and concluding that they are fundamentally unsupported. He opts for a “consequentialist” view of foundations. Nevertheless, he thinks that the modem welfare state is subject to effective critique along such lines. But rational contractarian individualism works and does provide foundations for libertarianism, while “consequentialism” is an ill‐defined theory.that is quite unpromising for the proposed critique; nevertheless, Friedman's empirical (...) and economic critique of the welfare state is valid.

This paper challenges the idea that there is a natural opposition between self-interest and morality. It does by developing an account of self-love according to which we can have self-regarding reasons that (1) differ substantially from the standard conception of self-interest, and that (2) share enough crucial features with moral reasons to count as morally respectable.

The concepts of uncertainty in prediction and inference are introduced and illustrated using the diffraction of light as an example. The close relationship between the concepts of uncertainty in inference and resolving power is noted. A general quantitative measure of uncertainty in inference can be obtained by means of the so-called statistical distance between probability distributions. When applied to quantum mechanics, this distance leads to a measure of the distinguishability of quantum states, which essentially is the absolute value of the (...) matrix element between the states. The importance of this result to the quantum mechanical uncertainty principle is noted. The second part of the paper provides a derivation of the statistical distance on the basis of the so-called method of support. (shrink)

The paper discusses the regularity account of causation but finds it insufficient as a complete account of our notion of causality. The attractiveness of the regularity account is its attempt to understand causation in terms of empirically accessible features of the world. However, this account does not match our intuition that singular causality is prior in normal epistemic situations and that there is more to causation than mere succession. Apart from succession and regularity, the concept of causality also contains a (...) modal feature which allows us to engage in counterfactual discourses about singular causal events and to claim that a particular cause is both sufficient and necessary for its effect in the circumstances. However, we may directly observe singular causes, but the modal element is not something we can possibly observe. Rather, this element is something we add to our perception of succession. Thus, the paper suggests that the modal feature of causality is a mental construction which was originally formed by our knowledge of certain structural features of similar events in other situations. It stems not from what we actually observe but from what we have observed or may observe under different but relevant circumstances. So the concept of causation has partly an empirical content and partly a constructed one. (shrink)

1. INTRODUCTION Professor Dworkin's writings on moral and political subjects have never failed to interest me in the past, and the two-part article “What is Equality” which is the subject of this paper, is no exception. Its wealth of relevant distinctions is bound to be useful to every serious student of the subject, whatever – or, in view of the range of opinions on these matters now current, perhaps I should say almost whatever – his ideological proclivities, and whether or (...) not he is sympathetic to Dworkin's position. The present treatment will be devoted, needless to say, primarily to disagreements, criticisms, and the raising of further questions, most of them designed to call in question either the general idea that equality should be regarded as a legitimate and important goal of social institutions or Dworkin's particular formulations of that equality. This largely negative-seeming consideration, I need scarcely add, is not intended to discount or detract from the positive contributions of Dworkin's work, which are very substantial indeed. It's just that having been ably set forth by Dworkin himself, they scarcely need seconding from this source. (shrink)

Despite its prominent role in cognitive psychology, its relevance for the research of consciousness, and some helpful clarification (e.g., Revonsuo 1999), the binding problem is still surrounded by considerable confusion. In this paper, I first give an informal but systematic overview on the diversity of forms the binding problem can assume, and then attempt to extract, on the basis of "working definitions" of various much-discussed types of binding, a common denominator. I propose that at the heart of the binding problem (...) lies the notion of representing an entity as having a certain property, and discuss several objections that could be raised against the proposed analysis, as well its usefulness and implications.

This papers discuss the place, if any, of Convention T (the condition of material adequacy of the proper definition of truth formulated by Tarski) in the truth-makers account offered by Kevin Mulligan, Peter Simons and Barry Smith. It is argued that although Tarski’s requirement seems entirely acceptable in the frameworks of truth-makers theories for the first-sight, several doubts arise under a closer inspection. In particular, T-biconditionals have no clear meaning as sentences about truth-makers. Thus, truth-makers theory cannot be considered as (...) the semantic theory of truth enriched by metaphysical (ontological) data. The problem of truth-makers for sentences about future events is discussed at the end of the paper. (shrink)

In this discussion, we will consider arguments against the view that one person is entitled to medical care at the expense of another person, just because the one person might be able to extend it to the other. We all accept the view that we are entitled to nonviolence from each other, which in the medical case is roughly that we are entitled to other people not making us sick, at least insofar as this is something they can readily avoid. (...) But how are we also entitled to their help in making us well when we are sick? Few of us think that we are entitled to other people's new cars, or half of their incomes for our general use. Why, then, are we entitled to a hefty fraction of that income to pay our medical bills? (shrink)
