A partial ordering in the class of observables (∼ positive operator-valued measures, introduced by Davies and by Ludwig) is explored. The ordering is interpreted as a form of nonideality, and it allows one to compare ideal and nonideal versions of the same observable. Optimality is defined as maximality in the sense of the ordering. The framework gives a generalization of the usual (implicit) definition of self-adjoint operators as optimal observables (von Neumann), but it can, in contrast to this latter definition, (...) be justified operationally. The nonideality notion is compared to other quantum estimation theoretic methods. Measures for the amount of nonideality are derived from information theory. (shrink)

Throughout more than two millennia philosophers adhered massively to ideal standards of scientific rationality going back ultimately to Aristotle’s Analytica posteriora . These standards got progressively shaped by and adapted to new scientific needs and tendencies. Nevertheless, a core of conditions capturing the fundamentals of what a proper science should look like remained remarkably constant all along. Call this cluster of conditions the Classical Model of Science . In this paper we will do two things. First of all, we will (...) propose a general and systematized account of the Classical Model of Science. Secondly, we will offer an analysis of the philosophical significance of this model at different historical junctures by giving an overview of the connections it has had with a number of important topics. The latter include the analytic-synthetic distinction, the axiomatic method, the hierarchical order of sciences and the status of logic as a science. Our claim is that particularly fruitful insights are gained by seeing themes such as these against the background of the Classical Model of Science. In an appendix we deal with the historiographical background of this model by considering the systematizations of Aristotle’s theory of science offered by Heinrich Scholz, and in his footsteps by Evert W. Beth. (shrink)

What's wrong with joining corona parties? In this article, I defend the idea that reasons to avoid such parties come in degrees. I approach this issue from a participation-based perspective. Specifically, I argue that the more people are already joining the party, and the more likely it is that the virus will spread among everyone, the stronger the participation-based reason not to join. In defense of these degrees, I argue that they covary with the expression of certain attitudes.

We present a conservative extension of a Bayesian account of confirmation that can deal with the problem of old evidence and new theories. So-called open-minded Bayesianism challenges the assumption—implicit in standard Bayesianism—that the correct empirical hypothesis is among the ones currently under consideration. It requires the inclusion of a catch-all hypothesis, which is characterized by means of sets of probability assignments. Upon the introduction of a new theory, the former catch-all is decomposed into a new empirical hypothesis and a new (...) catch-all. As will be seen, this motivates a second update rule, besides Bayes’ rule, for updating probabilities in light of a new theory. This rule conserves probability ratios among the old hypotheses. This framework allows for old evidence to confirm a new hypothesis due to a shift in the theoretical context. The result is a version of Bayesianism that, in the words of Earman, “keep[s] an open mind, but not so open that your brain falls out”. (shrink)

Strategic ignorance is a widespread phenomenon. In a laboratory setting, many participants avoid learning information about the consequences of their behaviour in order to act egoistically. In real life, many consumers avoid information about their purchases or the working conditions in which they were produced in order to retain their lifestyle. The question is whether agents are blameworthy for such strategically ignorant behaviour. In this paper, I explore quality of will resources, according to which agents are blameworthy, roughly, depending on (...) their moral concern. The account I will propose—the Maximal Account—has three innovative features: it utilizes a suitable concept of maximal moral concern, it offers an accountability version of the account which significantly differs from the more familiar attributability variant, and it maintains that agents without maximal concern are blameworthy.

In 2002, Belgium was the second country in the world to legalize euthanasia following the Netherlands. Since then, a few studies dealing with Belgium euthanasia practices have been published that are based on a survey given to a sample of physicians and nurses . All these studies from the past decade have implicitly proposed the practice of euthanasia as a medical act. Moreover, the last article published in this journal argued that the Belgian experiment concerning medical end-of-life decisions is unique (...) in the world and that the Belgian palliative care system, including euthanasia, should serve as a role-model for the rest of the world .The Belgium law provides a definition for euthanasia which lacks the analytical precision to apply it to medical studies .

Infinite regress arguments play an important role in many distinct philosophical debates. Yet, exactly how they are to be used to demonstrate anything is a matter of serious controversy. In this paper I take up this metaphilosophical debate, and demonstrate how infinite regress arguments can be used for two different purposes: either they can refute a universally quantified proposition (as the Paradox Theory says), or they can demonstrate that a solution never solves a given problem (as the Failure Theory says). (...) In the meantime, I show that Black’s view on infinite regress arguments (1996, this journal) is incomplete, and how his criticism of Passmore can be countered. (shrink)

According to Vallicella's 'Relations, Monism, and the Vindication of Bradley's Regress' (2002), if relations are to relate their relata, some special operator must do the relating. No other options will do. In this paper we reject Vallicella's conclusion by considering an important option that becomes visible only if we hold onto a precise distinction between the following three feature-pairs of relations: internality/externality, universality/particularity, relata-specificity/relata-unspecificity. The conclusion we reach is that if external relations are to relate their relata, they must be (...) relata-specific (and no special operator is needed). As it eschews unmereological complexes, this outcome is of relevance to defenders of the extensionality of composition. (shrink)

This paper concentrates on some aspects of the history of the analytic-synthetic distinction from Kant to Bolzano and Frege. This history evinces considerable continuity but also some important discontinuities. The analytic-synthetic distinction has to be seen in the first place in relation to a science, i.e. an ordered system of cognition. Looking especially to the place and role of logic it will be argued that Kant, Bolzano and Frege each developed the analytic-synthetic distinction within the same conception of scientific rationality, (...) that is, within the Classical Model of Science: scientific knowledge as cognitio ex principiis . But as we will see, the way the distinction between analytic and synthetic judgments or propositions functions within this model turns out to differ considerably between them. (shrink)

This book on infinite regress arguments provides (i) an up-to-date overview of the literature on the topic, (ii) ready-to-use insights for all domains of philosophy, and (iii) two case studies to illustrate these insights in some detail. Infinite regress arguments play an important role in all domains of philosophy. There are infinite regresses of reasons, obligations, rules, and disputes, and all are supposed to have their own moral. Yet most of them are involved in controversy. Hence the question is: what (...) exactly is an infinite regress argument, and when is such an argument a good one? (shrink)

Moral exemplars are often held up as objects to be admired. Such admiration is thought beneficial to the admirer, inducing him or her to emulate virtuous conduct, and deemed flattering to the admired. This paper offers a critical examination of admiration from a broadly Kantian perspective, arguing that admiration – even of genuine moral exemplars – violates the duty of self-respect. It also provides an explanation for the fact that moral exemplars themselves typically shun admiration. Lastly, it questions the assumption (...) that admiration leads to emulation on the basis of scientific findings that indicate that admiration induces passivity in the admirer rather than an incentive to self-improvement.

The view that persons are entitled to respect because of their moral agency is commonplace in contemporary moral theory. What exactly this respect entails, however, is far less uncontroversial. In this book, Van der Rijt argues powerfully that this respect for persons’ moral agency must also encompass respect for their subjective moral judgments – even when these judgments can be shown to be fundamentally flawed. Van der Rijt scrutinises the role persons’ subjective moral judgments play within the context of coercion (...) and domination. His fresh, original analysis of Kant’s third formulation of the Categorical Imperative reveals how these judgments are intimately connected to a person’s dignity. The result is an insightful new account of coercion, a novel Kantian reformulation of the republican notion of non-domination and a compelling, innovative argument in favour of retributive justice. "In this admirably clear and insightful work, Van der Rijt develops an original account of coercion and dignity. On the basis of his analysis of the relation between these two concepts, he also provides an intriguing new angle on the nature of republicanism. I recommend this book to anyone interested in freedom and power and their roles in normative political theory." Ian Carter - University of Pavia "In this carefully argued and original study Jan-Willem van der Rijt offers an analysis of coercion, a broadly Kantian argument that coercion is an affront to dignity, and an illuminating contrast with Philip Pettit's republicanism. A most welcome contribution." Thomas E. Hill, Jr. - University of North Carolina at Chapel Hill "Jan-Willem van der Rijt has written a well argued, original book that will prove to be extremely helpful for the philosophical inquiry of the relationship between coercion and human dignity as well as for the assessment of republicanism and its consequences."

List and Pettit have stated an impossibility theorem about the aggregation of individual opinion states. Building on recent work on the lottery paradox, this paper offers a variation on that result. The present result places different constraints on the voting agenda and the domain of profiles, but it covers a larger class of voting rules, which need not satisfy the proposition-wise independence of votes.

In this paper we examine the role the Dutch gymnasium continues to play in the institutional maintenance of educational inequality. To that end we examine the relational and spatial features of state-sponsored elite education in the Dutch system: the unique identity the gymnasium seeks to cultivate; its value to its consumers; its geographic significance; and its market position amidst a growing array of other selective forms of schooling. We argue that there is a strong correlation between a higher social class (...) background and the concern to transmit one’s cultural habitus. We further speculate on the moral implications of state-sponsored elite education, both as it concerns the specific role of the gymnasium in the reproduction of social inequality as well as the curious tendency among its supporters to rationalise the necessity of its existence.

Much of present-day epistemology is divided between internalists and externalists. Different as these views are, they have in common that they strip justification from its dialectical component in order to block the skeptic’s argument from disagreement. That is, they allow that one may have justified beliefs even if one is not able to defend it against challenges and resolve the disagreements about them. Lammenranta (2008, 2011a) recently argued that neither internalism nor externalism convinces if we consider the argument in its (...) most interesting format. In this paper I zoom in on this debate, and fix further details of Lammenranta’s lead. Specifically, I will side with skepticism that justification is dialectical, yet only if certain conditions are in place. (shrink)

This dissertation is on infinite regress arguments in philosophy. Its main goals are to explain what such arguments from many distinct philosophical debates have in common, and to provide guidelines for using and evaluating them. Two theories are reviewed: the Paradox Theory and the Failure Theory. According to the Paradox Theory, infinite regress arguments can be used to refute an existentially or universally quantified statement (e.g. to refute the statement that at least one discussion is settled, or the statement that (...) discussions are settled only if there is an agreed-upon criterion to settle them). According to the Failure Theory, infinite regress arguments can be used to demonstrate that a certain solution fails to solve an existentially or universally quantified problem (e.g. to demonstrate that a certain solution fails to settle all discussions, or that it fails to settle even one discussion). In the literature, the Paradox Theory is fairly well-developed, and this dissertation provides the Failure Theory with the same tools. (shrink)

Trust in vaccination is eroding, and attitudes about vaccination have become more polarized. This is an observational study of Twitter analyzing the impact that COVID-19 had on vaccine discourse. We identify the actors, the language they use, how their language changed, and what can explain this change. First, we find that authors cluster into several large, interpretable groups, and that the discourse was greatly affected by American partisan politics. Over the course of our study, both Republicans and Democrats entered the (...) vaccine conversation in large numbers, forming coalitions with Antivaxxers and public health organizations, respectively. After the pandemic was officially declared, the interactions between these groups increased. Second, we show that the moral and non-moral language used by the various communities converged in interesting and informative ways. Finally, vector autoregression analysis indicates that differential responses to public health measures are likely part of what drove this convergence. Taken together, our results suggest that polarization around vaccination discourse in the context of COVID-19 was ultimately driven by a trust-first dynamic of political engagement. (shrink)

We model three examples of beliefs that agents may have about other agents’ beliefs, and provide motivation for this conceptualization from the theory of mind literature. We assume a modal logical framework for modelling degrees of belief by partially ordered preference relations. In this setting, we describe that agents believe that other agents do not distinguish among their beliefs (‘no preferences’), that agents believe that the beliefs of other agents are in part as their own (‘my preferences’), and the special (...) case that agents believe that the beliefs of other agents are exactly as their own (‘preference refinement’). This multi-agent belief interaction is frame characterizable. We provide examples for introspective agents. We investigate which of these forms of belief interaction are preserved under three common forms of belief revision. (shrink)

The Access principle places an epistemic restriction on our obligations. This principle falls prey to the ‘Shirker Problem’, namely that shirkers could evade their obligations by evading certain epistemic circumstances. To block this problem, it has been suggested that shirkers have the obligation to learn their obligations. This solution yields a regress, yet it is controversial what the moral of the regress actually is. The aim of this paper is two-fold. First, I spell out this intricate dispute. Second, on the (...) basis of my analyses I propose solutions to the Shirker Problem. (shrink)

Zwischen 1934 und 1939 war die Zeitschrift für Sozialforschung für Walter Benjamin die zuverlässigste Publikationsmöglichkeit. Auch finanziell war Benjamin von der, vom ´Institut für Sozialforschung herausgegebenen, Zeitschrift abhängig. Zwei seiner wichtigsten Essays, L´oeuvre d´art à l´époque de sa reproduction mécanisée , Über einige Motive bei Baudelaire und vier weitere Beiträge erschienen in der Zeitschrift.Um die ersten beiden Texte entwickelten sich zwischen Adorno, der als Sachwalter der Redaktion auftrat, teilweise Horkheimer einerseits und Benjamin anderseits äußerst heftige Kontroversen. Es ging dabei nicht (...) nur darum, inwiefern marxistische Optionen unverhüllt ausgesprochen werden durften, sondern vor allem um systematische Fragen, die zwischen Adorno und Benjamin strittig waren und blieben. Mehr als die veröffentlichten Essays der beiden gibt der Briefwechsel zwischen Adorno und Benjamin überraschende Aufschlüsse über die tiefer liegenden, kontroversen Konzepte von Dialektik und anthropologischem Materialismus.

This contribution aims at deconstructing a Christian master narrative that interprets Josephus as crucial support for the New Testament message that the Temple had to become a ruin, in line with the will of God. It argues for an alternative interpretation, namely that both Jesus of Nazareth and Josephus considered the Temple to be still relevant, albeit in different ways. For Jesus the Temple was the self-evident cultic centre of Judaism and a special place to experience his relationship with God. (...) None of Jesus’ statements about the Temple in their original context necessarily implies that Jesus assumed that the institution of the Temple would stop functioning in the near future or at the end of time. Josephus’s perspective on the Temple changes in his works. The elaborate description of Jerusalem and the Temple in War 5 reads as a written monument of the past, but several passages in Josephus’s Antiquities and Against Apion imply that the Temple was still important after 70 CE. Josephus may have reckoned with the possibility that the Temple was going to be rebuilt if the Romans allowed for it.This contribution is dedicated to Pieter G.R. de Villiers, a modest but sophisticated scholar and a good friend.

In the following dialogue between TT - a foundationalist - and WdeV - a Sellarsian, we offer our differing assessments of the principle for observational knowledge proposed in Wilfrid Sellars's 'Empiricism and the Philosophy of Mind'. Sellars writes: 'For a Konstatierung "This is green" to "express observational knowledge", not only must it be a symptom or sign of the presence of a green object in standard conditions, but the perceiver must know that tokens of "This is green" are symptoms of (...) the presence of green objects in conditions which are standard for visual perception.' In the ensuing dialogue, TT argues that it sets the bar too high when knowledge about perceptual conditions is required for ordinary observational knowledge - that young children, for example, are implausibly excluded as knowers given Sellars's principle. WdeV defends Sellars's metaknowledge requirement against these charges. Results from developmental psychology are surveyed for what they show about the actual capabilities of young children. The implications of these results for the success of Sellars's principle are debated. (shrink)

If an argument can be reconstructed in at least two different ways, then which reconstruction is to be preferred? In this paper I address this problem of argument reconstruction in terms of Ryle’s infinite regress argument against the view that knowledge-how requires knowledge-that. First, I demonstrate that Ryle’s initial statement of the argument does not fix its reconstruction as it admits two, structurally different reconstructions. On the basis of this case and infinite regress arguments generally, I defend a revisionary take (...) on argument reconstruction: argument reconstruction is mainly to be ruled by charity (viz. by general criteria which arguments have to fulfil in order to be good arguments) rather than interpretation.

The Copenhagen interpretation is critically considered. A number of ambiguities, inconsistencies and confusions are discussed. It is argued that it is possible to purge the interpretation so as to obtain a consistent and reasonable way to interpret the mathematical formalism of quantum mechanics, which is in agreement with the way this theory is dealt with in experimental practice. In particular, the essential role attributed by the Copenhagen interpretation to measurement is acknowledged. For this reason it is proposed to refer to (...) it as a neo-Copenhagen interpretation.

The EPR problem is studied both from an instrumentalistic and from a realistic point of view. Bohr's reply to the EPR paper is analyzed and demonstrated to be not completely representative of Bohr's general views on the possibility of defining properties of a microscopic object. A more faithful Bohrian answer would not have led Einstein to the conclusion that Bohr's completeness claim of quantum mechanics implies nonlocality. The projection postulate, already denounced in 1936 by Margenau as the source of the (...) EPR paradox, is found to be also at the origin of the nonlocality conundrum. Its unobservability in EPR-like experiments is demonstrated, thus showing the redundancy of the idea of nonlocality in the instrumentalist interpretation of quantum mechanics. It is argued that also from a realist point of view there is no reason to assume nonlocality. The relevance of Bohm's quantum potential and of Bell's inequalities with respect to the (non)locality problem is discussed. (shrink)

This paper analyses the relationship between Hobbes's theory of language and his theory of science and method. It is shown that Hobbes, at least in his Computatio sive Logica (1655), deviates in some measure from the traditional (Aristotelian) model of language. In this model speech is considered to be a fairly unproblematic expression of thought, which itself is independent of language. Basing himself on a nominalist account of universals, Hobbes states that the demonstration or assertion of universal propositions presupposes speech (...) (more especially, the use of names as marks). This insight turns out to be essential for Hobbes's (rationalist) view of scientific method. (shrink)

While attention to research integrity has been growing over the past decades, the processes of signalling and denouncing cases of research misconduct remain largely unstudied. In this article, we develop a theoretically and empirically informed understanding of the causes and consequences of reporting research misconduct in terms of power relations. We study the reporting process based on a multinational survey at eight European universities. Using qualitative data that witnesses of research misconduct or of questionable research practices provided, we aim to (...) examine actors’ rationales for reporting and not reporting misconduct, how they report it and the perceived consequences of reporting. In particular we study how research seniority, the temporality of work appointments, and gender could impact the likelihood of cases being reported and of reporting leading to constructive organisational changes. Our findings suggest that these aspects of power relations play a role in the reporting of research misconduct. Our analysis contributes to a better understanding of research misconduct in an academic context. Specifically, we elucidate the processes that affect researchers’ ability and willingness to report research misconduct, and the likelihood of universities taking action. Based on our findings, we outline specific propositions that future research can test as well as provide recommendations for policy improvement. (shrink)

Pyrrhonism is the view that we should suspend all our beliefs in order to be rational and reach peace of mind. One of the main objections against this view is that it makes action impossible. One cannot suspend all beliefs and act normally at once. Yet, the question is: What is it about actions that they require beliefs? This issue has hardly been clarified in the literature. This is a bad situation, for if the objection fails and it turns out (...) that the Pyrrhonists found a way to secure peace of mind, we better know the details. In the following, I take up this systematic query and show how the objection can be made precise. Despite Sextus Empiricus? ingenious appearance/reality distinction, which is to ensure Pyrrhonism in this, I eventually argue that a life by appearances is quite unlike a normal life. (shrink)

The general view is that metaphysical explanation is asymmetric. For instance, if resemblance facts can be explained by facts about their relata, then, by the asymmetry of explanation, these latter facts cannot in turn be explained by the former. The question however is: is there any reason to hold on to the asymmetry? If so, what does it consist in? In the paper we approach these questions by comparing them to analogous questions that have been investigated for scientific explanations. Three (...) main asymmetry criteria have been proposed for the latter: (i) causation, (ii) unification, and (iii) explanatory dependence. We argue that the last criterion, but not the former two, can be of help to metaphysical explanation: metaphysical explanations are asymmetric if the explanatory dependence criterion (in modified format) holds of them.

At the end of Book 15 of his Res Gestae Ammianus Marcellinus reports how Strategius Musonianus became the successor of the murdered Domitianus as Praefectus Praetorio Orientis . He tells that Strategius was a man versed in the two languages, i.e. Greek and Latin, and that because of this he had won a higher distinction than was expected. When Constantine the Great, so says Ammianus, was looking for an expert interpreter for his investigation into the Manichaean and similar heresies, he (...) chose Strategius as a person recommended to him as competent. Constantine was so pleased with Strategius' skilful work that he gave him the honourable nickname Musonianus, which became his official name. This assignment was the start of a great career which eventually led to his denomination as PPO under Constantius II. (shrink)

What is the Problem of Universals? In this paper we take up the classic question and proceed as follows. In Sect. 1 we consider three problem solving settings and define the notion of problem solving accordingly. Basically I say that to solve problems is to eliminate undesirable, unspecified, or apparently incoherent scenarios. In Sect. 2 we apply the general observations from Sect. 1 to the Problem of Universals. More specifically, we single out two accounts of the problem which are based (...) on the idea of eliminating apparently incoherent scenarios, and then propose modifications of those two accounts which, by contrast, are based on the idea of eliminating unspecified scenarios. In Sect. 3 we spell out two interesting ramifications. (shrink)

Many global problems nowadays are collective action problems. It is only because many people act in some way that certain problems arise (e.g., climate harms). But when can one be said to participate in such groups in the first place? As Derek Parfit asked, “When we appeal to what groups together do, whom should we count as members of these groups?” As Julia Nefsky has shown, this problem has proven to be notoriously tricky, and without any adequate solution. We present (...) a solution. The proposed account not only overcomes a number of problems for participation-based views, according to which it is morally problematic to participate in such groups at all, but also helps make precise a prominent alternative view, according to which one should help bring about better outcomes.

Important sceptical arguments by Sextus Empiricus, Hume and Boghossian (concerning disputes, induction, and relativism respectively) are based on circularities and infinite regresses. Yet, philosophers' practice does not keep circularities and infinite regresses clearly apart. In this metaphilosophical paper I show how circularity and infinite regress arguments can be made explicit, and shed light on two powerful tools of the sceptic.

This paper is about the Problem of Order, which is basically the problem how to account for both the distinctness of facts like a’s preceding b and b’s preceding a, and the identity of facts like a’s preceding b and b’s succeeding a. It has been shown that the Standard View fails to account for the second part and is therefore to be replaced. One of the contenders is Anti-Positionalism. As has recently been pointed out, however, Anti-Positionalism falls prey to (...) a regress argument which is to prove its failure. In the paper we spell out this worry, show that the worry is a serious one, and distinguish four possible strategies for Anti-Positionalism to deal with it. (shrink)
