According to an influential view by Elizabeth Harman, moral ignorance, as opposed to factual ignorance, never excuses one from blame. In defense of this view, Harman appeals to the following considerations: that moral ignorance always implies a lack of good will, and that moral truth is always accessible. In this paper, I clearly distinguish these considerations, and present challenges to both. If my arguments are successful, sometimes moral ignorance excuses.

In the literature, regress arguments often take one of two different forms: either they conclude that a given solution fails to solve any problem of a certain kind (the strong conclusion), or they conclude that a given solution fails to solve all problems of a certain kind (the weaker conclusion). This gives rise to a logical problem: do regresses entail the strong or the weaker conclusion, or none? In this paper I demonstrate that regress arguments can in fact take both (...) forms, and clearly set out the logical difference between them. Throughout the paper, I confine myself to metaphysical examples from the early Russell. Only now that we know they are valid can we start to discuss whether they are sound. (shrink)

Many philosophers accept derivative blameworthiness for ignorant conduct – the idea that the blameworthiness for one’s ignorance can ‘transfer’ to blameworthiness for one’s subsequent ignorant conduct. In this chapter we ask the question what it actually means that blameworthiness would transfer, and explore four distinct views and their merits. On views (I) and (II), one’s overall degree of blameworthiness is determined by factors relevant to one’s ignorance and/or one’s subsequent conduct, and transfer only involves an increase in scope. On views (...) (III) and (IV), one’s overall degree of blameworthiness is determined by factors relevant to one’s ignorance as well as one’s subsequent conduct, and transfer might not only entail an increase in scope, but also in degree.

Michelle Moody-Adams suggests that “the main obstacle to moral progress in social practices is the tendency to widespread affected ignorance of what can and should already be known.” This explanation is promising, though to understand it we need to know what willful (affected, motivated, strategic) ignorance actually is. This paper presents a novel analysis of this concept, which builds upon Moody-Adams (1994) and is contrasted with a recent account by Lynch (2016).

We give a model for iterated belief change in multi-agent systems. The formal tool we use for this is a combination of modal and dynamic logic. Two core notions in our model are the expansion of the knowledge and beliefs of an agent, and the processing of new information. An expansion is defined as the change in the knowledge and beliefs of an agent when it decides to believe an incoming formula while holding on to its current propositional beliefs. To (...) prevent our agents from forming inconsistent beliefs they do not expand with every piece of information they receive. Instead, our agents remember their original beliefs and every piece of information they receive. After every receipt of information they decide which subset of the received information should be incorporated into their original beliefs. This procedure is called the processing of new information. We show that our model of belief update behaves in an intuitive way and that it is not sensitive to criticism on comparable models. (shrink)

This introduction provides an overview of the current state of the debate on the epistemic condition of moral responsibility. In sect. 1, we discuss the main concepts ‘ignorance’ and ‘responsibility’. In sect. 2, we ask why agents should inform themselves. In sect. 3, we describe what we take to be the core agreement among main participants in the debate. In sect. 4, we explain how this agreement invites a regress argument with a revisionist implication. In sect. 5, we provide an (...) overview of the main responses to the regress argument. In sect. 6, we address the question why blameless ignorance excuses. In sect. 7, we describe further issues that are addressed in the book. In sect. 8, we conclude with some discussion of future directions the debate might take. (shrink)

We represent consensus formation processes based on iterated opinion pooling as a dynamic approach to common knowledge of posteriors :1236–1239, 1976; Geanakoplos and Polemarchakis in J Econ Theory 28:192–200, 1982). We thus provide a concrete and plausible Bayesian rationalization of consensus through iterated pooling. The link clarifies the conditions under which iterated pooling can be rationalized from a Bayesian perspective, and offers an understanding of iterated pooling in terms of higher-order beliefs.

This paper explores the fact that linear opinion pooling can be represented as a Bayesian update on the opinions of others. It uses this fact to propose a new interpretation of the pooling weights. Relative to certain modelling assumptions the weights can be equated with the so-called truth-conduciveness known from the context of Condorcet's jury theorem. This suggests a novel way to elicit the weights.

In this paper I fix a typical regress argument, locate a typical gap in the argument, and try to supply a number of gap-filling readings of its first premise.

This paper concerns exchangeable analogical predictions based on similarity relations between predicates, and deals with a restricted class of such relations. It describes a system of Carnapian λγ rules on underlying predicate families to model the analogical predictions for this restricted class. Instead of the usual axiomatic definition, the system is characterized with a Bayesian model that employs certain statistical hypotheses. Finally the paper argues that the Bayesian model can be generalized to cover cases outside the restricted class of similarity (...) relations. (shrink)

This paper develops a probabilistic model of belief change under interpretation shifts, in the context of a problem case from dynamic epistemic logic. Van Benthem [4] has shown that a particular kind of belief change, typical for dynamic epistemic logic, cannot be modelled by standard Bayesian conditioning. I argue that the problems described by van Benthem come about because the belief change alters the semantics in which the change is supposed to be modelled: the new information induces a shift in (...) the interpretation of the sentences. In this paper I show that interpretation shifts can be modeled in terms of updating by conditioning. The model derives from the knowledge structures developed by Fagin et al [8], and hinges on a distinction between the propositional and informational content of sentences. Finally, I show that Dempster-Shafer theory provides the appropriate probability kinematics for the model. (shrink)

Rationality requires us to have certain propositional attitudes (beliefs, intentions, etc.) given certain other attitudes that we have. Carroll’s Tortoise repeatedly shows up in this discussion. Following up on Brunero (Ethical Theory Moral Pract 8:557–569, 2005), I ask what Carroll-style considerations actually prove. This paper rejects two existing suggestions, and defends a third.

BackgroundSexual boundary violations in healthcare are harmful and exploitative sexual transgressions in the professional–client relationship. Persons with mental health issues or intellectual disabilities, especially those living in residential settings, are especially vulnerable to SBV because they often receive long-term intimate care. Promoting good sexual health and preventing SBV in these care contexts is a moral and practical challenge for healthcare organizations.MethodsWe carried out a qualitative interview study with 16 Dutch policy advisors, regulators, healthcare professionals and other relevant experts to explore (...) their perspectives on preventing SBV in mental health and disability care organizations. We used inductive thematic analysis to interpret our data.ResultsWe found three main themes on how healthcare organizations can prevent SBV in mental health and disability care: setting rules and regulations, engaging in dialogue about sexuality, and addressing systemic and organizational dimensions.ConclusionOur findings suggest that preventing SBV in mental health and disability care organizations necessitates setting suitable rules and regulations and facilitating dialogue about positive aspects of sexuality and intimacy, as well as about boundaries, and inappropriate behaviors or feelings. Combining both further requires organizational policies and practices that promote transparency and reflection, and focus on creating a safe environment. Our findings will help prevent SBV and promote sexual health in mental health and disability care organizations. (shrink)

Should you reduce your energy consumption? Tragically enough, it may be better for you, and for everyone involved, to refrain from doing so even if you care about the climate. Given this tragedy, why cooperate? This paper defends the view that not cooperating is morally problematic because it is not universalizable (in a Kantian sense). That is, I will argue that we have universalizability-based reasons to cooperate as long as we have a preference for ‘collective success’ (e.g. a sustainable planet). (...) The problem is that defectors let others fix the problem for them, and in this way make an unfair exception of themselves. Moreover, even when selected agents might not share this preference, they still have to cooperate for the sake of others. (shrink)

Between 1940 and 1980, Ernest Mandel studied many aspects of capitalism. With his magna opera, Traité d'économie marxiste and Der Spätkapitalismus he had a great impact on the social movements which emerged in the 1960s and 1970s of the last century. This article attempts to unravel the story of the development of Mandel's economic historical work. It follows the search for the synthesis of late capitalism, positions Mandel in the Marxist tradition and looks for what was innovative in his contributions. (...) The Traité d'economie marxiste was a provocative experiment. The author shows how Mandel replaced history into the core of Marx's economic theory and how he supersedes Eurocentrism by independently asking for attention for Asia, Africa, the Islamic World and pre-Columbian America. Mandel worked on Der Spätkapitalismus for more than ten years. The article shows how Mandel rehabilitated the forgotten 'long-wave theory', which enabled him to offer an explanation for the exceptional postwar expansion, but also made him predict the end of the 'golden days of capitalism'. The study was completed in 1972 in a turbulent West Berlin, where as visiting professor at the leading Otto-Suhr-Institut für Politikwissenschaft he defended his vision in lively debate with students and confrères and where the last theoretical differences were ironed out.

Ernest Mandel theorised the capitalist world economy as an articulated system of capitalist, semi-capitalist and precapitalist relations of production, linked to each other by capitalist relations of exchange and domination by the capitalist world market. This seems to be an interesting starting point for an historically well-founded theory, building on and going beyond Marx's work, of the worldwide expansion of the capitalist mode of production from its origins to the present. In his attempt to formulate his theory, Mandel did not (...) succeed in resolving all difficulties, however. His main works – Marxist Economic Theory and Late Capitalism – show a number of dangling loose ends. The central question is whether these loose ends are merely technical difficulties or whether they reveal fatal flaws in the theory as a whole. In order to come a step closer to answering this question, a conference was organised in Amsterdam, November 2003. This introduction formulates the five, closely interrelated issues that were highlighted at this conference. (shrink)

Why act when the effects of one’s act are negligible? For example, why boycott sweatshop or animal products if doing so makes no difference for the better? According to recent proposals, one may still have a reason to boycott in order to avoid complicity or participation in harm. Julia Nefsky has argued that accounts of this kind suffer from the so-called “superfluity problem,” basically the question of why agents can be said to participate in harm if they make no difference (...) to it. This paper develops and responds to Nefsky’s challenge. (shrink)

It is widely assumed that it is rational to suspend one’s belief regarding a certain proposition only if one’s evidence is neutral regarding that proposition. In this paper I broaden this condition, and defend, on the basis of an improved ancient argument, that it is rational to suspend one’s belief even if the available evidence is not neutral – or even close to neutral.

Deliberation is the process through which we decide what do to, or what to believe. When we think about what to do, we are engaged in practical deliberation. Theoretical deliberation is when we think about what to believe, or about which judgement to make.

According to Alexander Sarch, criminal culpability is a special kind of culpability, which moreover comes in degrees.1 This paper critically examines his acc...

Does willful ignorance mitigate blameworthiness? In many legal systems, willfully ignorant wrongdoers are considered as blameworthy as knowing wrongdoers. This is called the ‘equal culpability thesis’. Given that legal practice depends on it, the issue has obvious importance. Interestingly enough, however, there exists hardly any philosophical reflection on ECT. A recent exception is Alexander Sarch, who defends a restricted version of ECT. On Sarch’s view, ECT is true whenever willfully ignorant agents incur additional blameworthiness for their ignorance. In this paper, (...) I defend an alternative view, according to which ECT is true whenever the motives of willfully ignorant and knowing wrongdoers are equally bad. (shrink)

In V. N. Huynh (ed.): Interval / Probabilistic Uncertainty and Non-Classical Logics, Advances in Soft Computing Series, Springer 2008, pp. 268-279. This paper proposes a common framework for various probabilistic logics. It consists of a set of uncertain premises with probabilities attached to them. This raises the question of the strength of a conclusion, but without imposing a particular semantics, no general solution is possible. The paper discusses several possible semantics by looking at it from the perspective of probabilistic argumentation.

In this paper I discuss probabilistic models of experimental intervention, and I show that such models elucidate the intuition that observations during intervention are more informative than observations per se. Because of this success, it seems attractive to also cast other problems addressed by the philosophy of experimentation in terms of such probabilistic models. However, a critical examination of the models reveals that some of the aspects of experimentation are covered up rather than resolved by probabilistic modelling. I end by (...) drawing a number of general lessons on the use of formal methods in the philosophy of science. (shrink)

This article presents a generalization of the Condorcet Jury Theorem. All results to date assume a fixed value for the competence of jurors, or alternatively, a fixed probability distribution over the possible competences of jurors. In this article, we develop the idea that we can learn the competence of the jurors by the jury vote. We assume a uniform prior probability assignment over the competence parameter, and we adapt this assignment in the light of the jury vote. We then compute (...) the posterior probability, conditional on the jury vote, of the hypothesis voted over. We thereby retain the central results of Condorcet, but we also show that the posterior probability depends on the size of the jury as well as on the absolute margin of the majority. (shrink)

This article comments on the article of Thorn and Schurz in this volume and focuses on, what we call, the problem of parasitic experts. We discuss that both meta- induction and crowd wisdom can be understood as pertaining to absolute reliability rather than comparative optimality, and we suggest that the involvement of reliability will provide a handle on this problem.

This article critically reviews a new collection on Pyrrhonism edited by Diego Machuca, Pyrrhonism in Ancient, Modern, and Contemporary Philosophy, which fits within the recent focus on the systematic, philosophical import of Pyrrhonism. In this article I both situate and summarize the problems posed by the authors regarding the Pyrrhonist's position (concerning its coherence, its theoretical motivation, and its practical motivation), and indicate to what extent Pyrrhonists might be able to meet them. I conclude that, so far, Pyrrhonism, i.e. the (...) view which propagates global suspension of belief, remains a promising option. (shrink)

We consider the use of interventions for resolving a problem of unidentified statistical models. The leading examples are from latent variable modelling, an influential statistical tool in the social sciences. We first explain the problem of statistical identifiability and contrast it with the identifiability of causal models. We then draw a parallel between the latent variable models and Bayesian networks with hidden nodes. This allows us to clarify the use of interventions for dealing with unidentified statistical models. We end by (...) discussing the philosophical and methodological import of our result. (shrink)

Over the past decades or so the probabilistic model of rational belief has enjoyed increasing interest from researchers in epistemology and the philosophy of science. Of course, such probabilistic models were used for much longer in economics, in game theory, and in other disciplines concerned with decision making. Moreover, Carnap and co-workers used probability theory to explicate philosophical notions of confirmation and induction, thereby targeting epistemic rather than decision-theoretic aspects of rationality. However, following Carnap’s early applications, philosophy has more recently (...) seen an increased popularity of probabilistic models in other areas concerned with the philosophical analysis of belief: there are models targeting coherence, informativeness, simplicity, and so on.In brief, the probabilistic model of belief comprises of a language, detailing the propositions about which an agent is supposed to have beliefs, and a function over the language that expresses beliefs: ..

Suspension of Judgment What does it take to suspend one’s judgment? In this introduction to the special issue ‘Scepticism and the suspension of judgment’, I present a conceptual analysis of suspension of judgment (what it is, what it isn’t, and why we might want to do it). Basically I argue that suspension is a mental attitude of neutrality. If you suspend judgment on a certain proposition, you are neutral towards its truth. In addition, I make a few suggestions on how (...) to further analyse this attitude of neutrality, and distinguish it from other attitudes such as doubt and inquisitiveness. (shrink)

This paper studies the use of hypotheses schemes in generatinginductive predictions. After discussing Carnap–Hintikka inductive logic,hypotheses schemes are defined and illustrated with two partitions. Onepartition results in the Carnapian continuum of inductive methods, the otherresults in predictions typical for hasty generalization. Following theseexamples I argue that choosing a partition comes down to making inductiveassumptions on patterns in the data, and that by choosing appropriately anyinductive assumption can be made. Further considerations on partitions makeclear that they do not suggest any solution (...) to the problem of induction.Hypotheses schemes provide the tools for making inductive assumptions, but theyalso reveal the need for such assumptions.

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)

Most models of the formation of political coalitions use either Euclidean spaces or rely purely on game theory. This limits their applicability. In this article, a single model is presented which is more broadly applicable. In principle any kind of set can be used as a policy space. The model is also able to incorporate different kinds of party motivations: both rent-seeking and idealism. The model uses party preferences and power to identify stable coalitions and predict government policy as well (...) as to indicate which member of the opposition will be able to break up the governing coalition if no stable coalition exists. In the latter case it will also indicate on which issue the government is likely to split. Parties may have preferences over issues such as the composition of cabinet and/or the governing coalition as well as the more traditional issues of government formation. The model also provides a rationale for log-rolling. (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.

This article investigates a problem for statistical model evaluation, in particular for curve fitting: by employing a different family of curves we can fit any scatter plot almost perfectly at apparently minor cost in terms of model complexity. The problem is resolved by an appeal to prior probabilities. This leads to some general lessons about how to approach model evaluation.

Cancers often express hundreds of genes otherwise specific to germ cells, the germline/cancer (GC) genes. Here, we present and discuss the hypothesis that activation of a “germline program” promotes cancer cell malignancy. We do so by proposing four hallmark processes of the germline: meiosis, epigenetic plasticity, migration, and metabolic plasticity. Together, these hallmarks enable replicative immortality of germ cells as well as cancer cells. Especially meiotic genes are frequently expressed in cancer, implying that genes unique to meiosis may play a (...) role in oncogenesis. Because GC genes are not expressed in healthy somatic tissues, they form an appealing source of specific treatment targets with limited side effects besides infertility. Although it is still unclear why germ cell specific genes are so abundantly expressed in cancer, from our hypothesis it follows that the germline's reproductive program is intrinsic to cancer development.

Can Kantians distinguish unfair free riding from innocent coordination? If they cannot, the whole approach is flawed. This paper develops a novel solution. Free riders, as I will put it, fail to make their conduct conditional on other people’s preferences. They refuse to do their part regardless of what others prefer. It is not just that other people share the same preferences - as alternative accounts have it - but that the free rider does not care whether they do or (...) do not share the same preferences. The same does not carry over to innocent coordination. (shrink)

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)
