In this paper, I describe some aspects of the phenomenon of "experimental mathematics" in order to discuss whether it constitutes a subdiscipline or a particular style of mathematics. My conclusion is that neither of these notions accurately capture the complex culture of experimental mathematics.

Since 2004, it has been mandated by law that all Danish undergraduate university programmes have to include a compulsory course on the philosophy of science for that particular program. At the Faculty of Science and Technology, Aarhus University, the responsibility for designing and running such courses were given to the Centre for Science Studies, where a series of courses were developed aiming at the various bachelor educations of the Faculty. Since 2005, the Centre has been running a dozen different courses (...) ranging from mathematics, computer science, physics, chemistry over medical chemistry, biology, molecular biology to sports science, geology, molecular medicine, nano science, and engineering. -/- We have adopted a teaching philosophy of using historical and contemporary case studies to anchor broader philosophical discussions in the particular subject discipline under consideration. Thus, the courses are tailored to the interests of the students of the particular programme whilst aiming for broader and important philosophical themes as well as addressing the specific mandated requirements to integrate philosophy, some introductory ethics, and some institutional history. These are multiple and diverse purposes which cannot be met except by compromise. -/- In this short presentation, we discuss our ambitions for using case studies to discuss philosophical issues and the relation between the specific philosophical discussions in the disciplines and the broader themes of philosophy of science. We give examples of the cases chosen to discuss various issues of scientific knowledge, the role of experiments, the relations between mathematics and science, and the issues of responsibility and trust in scientific results. Finally, we address the issue of how and why science students can be interested in and benefit from mandatory courses in the philosophy of their subject. (shrink)

Immanuel Kant promised, ‘as Your Majesty's loyal subject’, to abstain from all public lectures about religion. All past commentators agree this phrase permitted Kant to return to the topic after the King died. But it is not part of the ‘at-issue content’. Consequently, ‘as Your Majesty's loyal subject’ is no more an escape clause than the corresponding phrase in ‘I guarantee, as your devoted fan, that these guitar strings will not break’. Just as the guarantee stands regardless of whether the (...) guarantor ceases to be your devoted fan, the compliance conditions of Kant's promise are not affected by Kant's ceasing to be the king's loyal subject. For good or ill, Kant made a lying promise to King Friedrich Wilhelm II in 1794. (shrink)

If there is to be any progress in the debate about what sort of positive moral status Kant can give the emotions, we need a taxonomy of the terms Kant uses for these concepts. It used to be thought that Kant had little room for emotions in his ethics. In the past three decades, Marcia Baron, Paul Guyer, Barbara Herman, Nancy Sherman, Allen Wood and others have argued otherwise. Contrary to what a cursory reading of the Groundwork may indicate, Kant (...) thinks the emotions play an important role in the moral life. I want to extend the work of Baron, Guyer, Herman, Sherman and Wood in three ways. First, I will set out in a diagram Kant's taxonomy of feelings and emotions. Agreement on such a taxonomy should make it easier to evaluate debates about Kant and the emotions. Second, I will focus on a certain subclass of emotions – reason-caused affects – that have previously received little attention, even from these Kant scholars. Third, these scholars base much of their defence of Kant on his later works – especially the Metaphysics of Morals and the Anthropology – but Kant's fairly rich taxonomy of the emotions, including reason-caused affects, is clearly in place at least as early as the Critique of Judgment . I believe that the Critique of Judgment is an importantly ignored resource for understanding the moral role of the emotions for Kant. The third Critique makes positive, philosophically interesting claims about the emotions and morality. Kant emphasizes certain roles for emotions in this work that he develops to the same extent nowhere else. Nevertheless, the Critique of Judgment goes all but unmentioned by many who write on these issues. In what follows, I will defend as many of my claims as possible using the third Critique. (shrink)

People often fail to comply with the demands of morality. Partial compliance theory takes this noncompliance or its possibility into account in the formulation of moral requirements for people to comply with, or in the evaluation of people’s actions against those requirements. This chapter critically engages with recent work on partial compliance theory. It examines the relationship between noncompliance and injustice, assesses different ways of doing partial compliance theory, sketches the relationship between partial compliance theory and other central methodological debates (...) in moral and political philosophy, and considers whether it is reasonable to issue moral requirements without examining what would happen if everyone did their part.

Charitable interpreters of David Hume set aside his sprinkles of piety. Better to read him as lying than as clumsily inconsistent. We argue that the attribution of lies can pay dividends in historical scholarship no matter how strongly the theorist condemns lying. Accordingly, we show that our approach works even with one of the strongest condemners of lying: Immanuel Kant. We argue that Kant lied in his scholarly work and even in the first Critique. And we defend the claim that (...) this lie attribution, strange as it may sound, amounts to a kind of scholarly charity. (shrink)

In this paper, we engage with the question of the normative content of the resilience concept. The issues are approached in two consecutive steps. First, we proceed from a narrow construal of the resilience concept – as the ability of a system to absorb a disturbance – and show that under an analysis of normative concepts as evaluative concepts resilience comes out as descriptive. In the second part of the paper, we argue that (1) for systems of interest (primarily social (...) systems or system with a social component) we seem to have options with respect to how they are described and (2) that this matters for what is to be taken as a sign of resilience as opposed to a sign of the lack of resilience for such systems. We discuss the implications of this for how the concept should be applied in practice and suggest that users of the resilience concept face a choice between versions of the concept that are either ontologically or normatively charged.

Public reason liberalism demands that political decisions be publicly justified to the citizens who are subjected to them. Much recent literature emphasises the differences between the two main interpretations of this requirement, justificatory and political liberalism. In this paper, I show that both views share structural democratic deficits. They fail to guarantee political autonomy, the expressive quality of law, and the justification to citizens, because they allow collective decisions made by incompletely theorised agreements. I argue that the result can only (...) be avoided by changing public reason’s role in collective decision-making. Instead of incompletely theorised agreements, we should demand agreement both on the public reasons themselves and on the other premises that justify political decisions. In this way, it is always possible to point to a procedure-independent reason that justifies democratic decisions, and the reasoning of the state is public and contestable. Finally, I explain how this, in turn, implies that only political liberalism can be rescued—by accepting what I will call strong political liberalism. Modifying justificatory liberalism in the necessary way will inevitably open the door to an objectionable form of perfectionism. (shrink)

Many democratic theorists hold that when a decision is collectively made in the right kind of way, in accordance with the right procedure, it is permissible to enforce it. They deny that there are further requirements on the type of reasons that can permissibly be used to justify laws and policies. In this paper, I argue that democratic theorists are mistaken about this. So-called public reason requirements follow from commitments that most of them already hold. Drawing on the democratic ideal (...) of civic equality, I show that it can successfully explain why political decision-making must have the right sort of procedure-independent justification. However, contra standard accounts of public reason, I argue that laws and policies need to be justified with convergence accessible, not shared, reasons. Public reasons are those that are accessible in light of evaluative standards shared by all, or in light of every citizen’s private evaluative standards. Since this will make the set of public reasons wider, it makes the theory more palatable to sceptics while retaining the framework’s justificatory potential. (shrink)

The idea that technologies can change moral beliefs and practices is an old one. But how, exactly, does this happen? This paper builds on an emerging field of inquiry by developing a synoptic taxonomy of the mechanisms of techno-moral change. It argues that technology affects moral beliefs and practices in three main domains: decisional (how we make morally loaded decisions), relational (how we relate to others) and perceptual (how we perceive situations). It argues that across these three domains there are (...) six primary mechanisms of techno-moral change: (i) adding options; (ii) changing decision-making costs; (iii) enabling new relationships; (iv) changing the burdens and expectations within relationships; (v) changing the balance of power in relationships; and (vi) changing perception (information, mental models and metaphors). The paper also discusses the layered, interactive and second-order effects of these mechanisms. (shrink)

In this article, I have two aims. Firstly, I argue that Hilary Putnam's model theoretic indeterminacy argument against external realism and Saul Kripke's so-called Kripkensteinian argument against semantic realism have the same dialectical structure and the same conclusion---both force the opponent to face the same dilemma. Namely: either adopt meaning minimalism or postulate unobservable semantic facts. Secondly, I analyze more closely the first horn of the dilemma---meaning minimalism. This is the position according to which there are no truth conditions for (...) meaning-ascriptions. It has been suggested that this position is incoherent. However, I argue that there is a coherent option available for the meaning minimalist. As Crispin Wright has proposed, a coherent meaning minimalist has to adopt a structured truth-predicate with at least two levels: one is a minimal or a deflationary truth-predicate for a semantic discourse and the other, more substantial or objective truth-predicate for discourses like natural sciences. Subsequently, this leads to a position close to Huw Price's global expressivism. Thus, the ultimate dilemma that Putnam's and the Kripkensteinian argument establish is the following choice: either meaning minimalism with a structured two-level truth-predicate or robust realism regarding meaning.

In this article I am interpreting Friedrich Nietzsche's piece of writing "How the "True World" finally became a fable - The History of an Error" in the context of 20th-century analytical philosophy of language. In particular, I am going to argue that the main theme in this text - the issue of abolishing "the true world" - can be interpreted as Hilary Putnam's model-theoretic arguments against external realism and Saul Kripke's Wittgensteinian arguments against truth-conditional meaning theories. Interpreting this Nietzsche's text (...) with the help of these arguments gives rise to two options determining Nietzsche's own position. The perspective of Putnam's argument seems to push Nietzsche to the quietist camp - the view that significant metaphysical debate between external realism and its opposite is impossible or inexpressible. On the other hand, the Kripkensteinian perspective gives us reasons to interpret Nietzsche as an adherer of the pragmatic account of semantics, which explains meaning through the use of language.

The thesis investigates the implications for moral philosophy of research in psychology. In addition to an introduction and concluding remarks, the thesis consists of four chapters, each exploring various more specific challenges or inputs to moral philosophy from cognitive, social, personality, developmental, and evolutionary psychology. Chapter 1 explores and clarifies the issue of whether or not morality is innate. The chapter’s general conclusion is that evolution has equipped us with a basic suite of emotions that shape our moral judgments in (...) important ways. Chapter 2 presents and investigates the challenge presented to deontological ethics by Joshua Greene’s so-called dual process theory. The chapter partly agrees with his conclusion that the dual process view neutralizes some common criticisms against utilitarianism founded on deontological intuitions, but also points to avenues left to explore for deontologists. Chapter 3 focuses on Katarzyna de Lazari-Radek and Peter Singer’s suggestion that utilitarianism is less vulnerable to so-called evolutionary debunking than other moral theories. The chapter is by and large critical of their attempt. In the final chapter 4, attention is directed at the issue of whether or not social psychology has shown that people lack stable character traits, and hence that the virtue ethical view is premised on false or tenuous assumptions. Though this so-called situationist challenge at one time seemed like a serious threat to virtue ethics, the chapter argues for a moderate position, pointing to the fragility of much of the empirical research invoked to substantiate this challenge while also suggesting revisions to the virtue-ethical view as such.

This paper examines precursors and consequents of perceived relevance of a proposition A for a proposition C. In Experiment 1, we test Spohn's assumption that ∆P = P − P is a good predictor of ratings of perceived relevance and reason relations, and we examine whether it is a better predictor than the difference measure − P). In Experiment 2, we examine the effects of relevance on probabilistic coherence in Cruz, Baratgin, Oaksford, and Over's uncertain “and-to-if” inferences. The results suggest (...) that ∆P predicts perceived relevance and reason relations better than the difference measure and that participants are either less probabilistically coherent in “and-to-if” inferences than initially assumed or that they do not follow P = P. Results are discussed in light of recent results suggesting that the Equation may not hold under conditions of irrelevance or negative relevance. (shrink)

In this paper we consider Mark Bedau’s notion of weak emer- gence (WE) and relate it to various attempts to objectively construe complexity. We argue that the heavy reliance on a specific notion of complexity risks rendering the concept superfluous. Furthermore we discuss what sort of systems might reasonably be understood as exhibiting emergence at all and point out that the macro-level needs to be at least min- imally structured. A worry may thus be formed that macro- level generalisations provide (...) the sort of short-cut that is ex- plicitly excluded from WE thus potentially making the con- cept apply only to chaotic systems of limited interest (in this context).

Today research on prosocial behaviour is very much shaped by the success of social neuroscience. However, some philosopher's criticise neuroscience as reductionist. The purpose of this paper is to analyse this critique. With a philosophical background in Charles Taylor's hermeneutic thesis "man as a self-interpreting animal", the paper shows that neuroscientists' attempt to describe prosocial behaviour in science through brain imaging technologies (MRI) constitute a neurochemical self that resonates a modern ‘paradigm of clarity and objectivity’ as presented by Taylor. It (...) is argued that this scientific explanation model challenges Taylor's hermeneutic self. Where human behaviour previous was mapped on a psychological level, prosocial behaviour is described in the body - the human brain - on a neurophysiological level. The author applies an autism analogy metaphor, which paradoxical shows that the neurochemical self’s emphasis on structures and observations epistemological facilitate an autistic understanding of prosocial behaviour alien to the situated and interpreted feelings of Taylor's self-understanding(s), and the logic of our everyday language.

This article argues that actor-network theory, as an alternative to critical theory, has lost its critical impetus when examining commodification in healthcare. The paper claims that the reason for this, is the way in which actor-network theory’s anti-essentialist ontology seems to black box 'intentionality' and ethics of human agency as contingent interests. The purpose of this paper was to open the normative black box of commodification, and compare how Marxism, Habermas and ANT can deal with commodification and ethics in healthcare. (...) Moreover, a new account of 'intentionality' in critical thinking was elaborated. Using Strawson's analysis of 'reactive attitudes and resentment,' the ethical implications of commodification in health care were examined as an assessment of intentions. Synthesizing critical theory with the relational materialism of actor-network theory, this article advances a new approach that seeks to bridge interdisciplinary boundaries, and guide actor-network theory in a critical and humanist direction. Providing new theoretical insights on commodification and 'intentionality' in health care. (shrink)

By definition, pain is a sensory and emotional experience that is felt in a particular part of the body. The precise relationship between somatic events at the site where pain is experienced, and central processing giving rise to the mental experience of pain remains the subject of debate, but there is little disagreement in scholarly circles that both aspects of pain are critical to its experience. Recent experimental work, however, suggests a public view that is at odds with this conceptualisation. (...) By demonstrating that the public does not necessarily endorse central tenets of the “mental” view of pain (subjectivity, privacy, and incorrigibility), experimental philosophers have argued that the public holds a more “body-centric” view than most clinicians and scholars. Such a discrepancy would have important implications for how the public interacts with pain science and clinical care. In response, we tested the hypothesis that the public is capable of a more “mind-centric” view of pain. Using a series of vignettes, we demonstrate that in situations which highlight mental aspects of pain the public can, and does, recognize pain as a mental phenomenon. We also demonstrate that the public view is subject to context effects, by showing that the public’s view is modified when situations emphasizing mental and somatic aspects of pain are presented together.

This essay discusses Cecilia Heyes’ groundbreaking new book Cognitive Gadgets: The Cultural Evolution of Thinking. Heyes’ point of departure is the claim that current theories of cultural evolution fail adequately to make a place for the mind. Heyes articulates a cognitive psychology of cultural evolution by explaining how eponymous “cognitive gadgets,” such as imitation, mindreading and language, mental technologies, are “tuned” and “assembled” through social interaction and cultural learning. After recapitulating her explanations for the cultural and psychological origins of these (...) gadgets, we turn to criticisms. Among those, we find Heyes’ use of evolutionary theory confusing on several points of importance; alternative theories of cultural evolution, especially those of the Tomasello group and of Boyd, Richerson and Henrich, are misrepresented; the book neglects joint attention and other forms of intersubjectivity in its explanation of the origins of cognitive gadgets; and, whereas Heyes accuses other theories of being “mindblind,” we find her theory ironically other-blind and autistic in character.

We are in a time of rapid change on multiple levels. Change can be seen as positive by one group and negative by another. As a result, different perspectives on any given change can draw completely different conclusions. In these proceedings we want to address different approaches to change from all kinds of perspectives within the realm of citizen science and participatory research. We discuss both active, transformative change, and the observation of change monitored by citizen science in all kinds (...) of disciplines. We highlight the potential of citizen science to be a change maker in research and society, and as a tool to manage the change happening around us. The proceedings "Change - The transformative power of citizen science" showcase a selection of topics that have been presented and discussed at the ECSA/ACSC 2024 double conference in Vienna and highlight the transformative power, citizen science can have.

In this chapter, we argue that in order to understand the interdisciplinary and transdisciplinary dialectics in sustainability science, it is useful to see sustainability science as a kind of management science, and then to highlight the hard-soft distinction in systems thinking. First, we argue that the commonly made natural-social science dichotomy is relatively unimportant and unhelpful. We then outline the differences between soft and hard systems thinking as a more relevant and helpful distinction, mainly as a difference between perspectives in (...) systemic modeling toward models. We also illustrate that the distinction is methodologically useful to advance sustainability science by enabling us (i) to suggest novel ways of using existing theoretical, experimental, and computational resources of the sciences for renewable resource management, and (ii) to disentangle disciplinary disagreements in climate science.

The aim of this book, written by a researcher at the Tatarstan Academy of Sciences, is to examine how and why theories change in science. Nugayev’s analysis, and his many examples, are confined to mathematically formalized theories of physics. Nugayev’s ideas are inspired by, and relate to, Russian scholars. His approach is primarily philosophical and clearly in the analytical tradition of Popper, Kuhn, Lakatos, Feyerabend, Stegmuller and others. Although Nugayev’s book is primarily addressed to philosophers, it is also of interest (...) to the philosophically inclined historian of science. (shrink)

Social norms regulating carework and social reproduction tend to be inegalitarian. At the same time, such norms often play a crucial role when we plan our lives. How can we criticise objectionable practices while ensuring that people can organise their lives around meaningful and predictable rules? Gerald Gaus argues that only ‘publicly justified’ rules, rules that everyone would prefer over ‘blameless liberty,’ should be followed. In this paper, we uncover the inegalitarian implications of this feature of Gaus's framework. We show (...) that because a society without clear social norms for how social reproduction and care work ought to be organised would be so unattractive, inegalitarian rules would pass Gaus's test. They would pass this test since they would nevertheless be better than ‘blameless liberty.’ Those who are disproportionately burdened by a rule are faced with the daunting task of showing that they would be better off under no rule, instead of merely having to show that they would be better off with a different rule.

Sustainability science seeks to extend scientific investigation into domains characterized by a distinct problem-solving agenda, physical and social complexity, and complex moral and ethical landscapes. In this endeavor it arguably pushes scientific investigation beyond its usual comfort zones, raising fundamental issues about how best to structure such investigation. Philosophers of science have long scrutinized the structure of science and scientific practices, and the conditions under which they operate effectively. We propose a critical engagement between sustainability scientists and philosophers of science (...) with respect to how to engage in scientific activity in these complex domains. We identify specific issues philosophers of science raise concerning current sustainability science and the contributions philosophers can make to resolving them. In conclusion we reflect on the steps philosophers of science could take to advance sustainability science. (shrink)

It is unknown to what extent medical researchers generalize study findings beyond their samples when their sample size, sample diversity, or knowledge of conditions that support external validity do not warrant it. It is also unknown to what extent medical researchers describe their results with precise quantifications or unquantified generalizations, i.e., generics, that can obscure variations between individuals. We therefore systematically reviewed all prospective studies (n = 533) published in the top four highest ranking medical journals, Lancet, New England Journal (...) of Medicine (NEJM), Journal of the American Medical Association (JAMA), and the British Medical Journal (BMJ), from January 2022 to May 2023. We additionally reviewed all NEJM Journal Watch clinical research summaries (n = 143) published during the same time. Of all research articles reporting prospective studies, 52.5% included generalizations beyond specific national study populations, with the numbers of articles with generics varying significantly between journals (JAMA = 12%; Lancet = 77%) (p < 0.001, V = 0.48). There was no evidence that articles containing broader generalizations or generics were correlated with larger or more nationally diverse samples. Moreover, only 10.2% of articles with generalizations beyond specific national populations reported external validity strengthening factors that could potentially support such extrapolations. There was no evidence that original research articles and NEJM Journal Watch summaries intended for practitioners differed in their use of broad generalizations, including generics. Finally, from the journal with the highest citation impact, articles containing broader conclusions were correlated with more citations. Since there was no evidence that studies with generalizations beyond specific national study populations or with generics were associated with larger, more nationally diverse samples, or with reports of population similarity that may permit extensions of conclusions, our findings suggest that the generalizations in many articles were insufficiently supported. Caution against overly broad generalizations in medical research is warranted. (shrink)

This paper argues that the main global critiques of scientism lose their punch because they rely on an uncharitable definition of their target. It focuses on epistemological scientism and divides it into four categories in terms of how strong (science is the only source of knowledge) or weak (science is the best source of knowledge) and how narrow (only natural sciences) or broad (all sciences or at least not only the natural sciences) they are. Two central arguments against scientism, the (...) (false) dilemma and self‐referential incoherence, are analysed. Of the four types of epistemological scientism, three can deal with these counterarguments by utilizing two methodological principles: epistemic evaluability of reliability and epistemic opportunism. One hopes that these considerations will steer the discussion on scientism to more fruitful pastures in the future. For example, there are interesting methodological considerations concerning what evaluability or reliability and epistemic opportunism entail. (shrink)

A consistent finding in research on conditional reasoning is that individuals are more likely to endorse the valid modus ponens (MP) inference than the equally valid modus tollens (MT) inference. This pattern holds for both abstract task and probabilistic task. The existing explanation for this phenomenon within a Bayesian framework (e.g., Oaksford & Chater, 2008) accounts for this asymmetry by assuming separate probability distributions for both MP and MT. We propose a novel explanation within a computational-level Bayesian account of reasoning (...) according to which “argumentation is learning”. We show that the asymmetry must appear for certain prior probability distributions, under the assumption that the conditional inference provides the agent with new information that is integrated into the existing knowledge by minimizing the Kullback-Leibler divergence between the posterior and prior probability distribution. We also show under which conditions we would expect the opposite pattern, an MT-MP asymmetry. (shrink)

Roy Sorensen has discussed a scenario he calls 'the Disappearing Act', introduced a puzzle based on this scenario, and offered a solution to this puzzle. We argue against Sorensen's solution and offer our own.

Short review of Helge Kragh's excellent book on the contest between big bang and steady state theories of the universe.

In his book “Seeing Dark Things” (2008), Roy Sorensen provides many wonderfully ingenious arguments for many surprising, counter-intuitive claims. One such claim in particular is that when we a silhouetted object – i.e. an opaque object lit entirely from behind – we literally see its back-side – i.e. we see the full expanse of the surface facing away from us that is blocking the incoming light. Sorensen himself admits that this seems a tough pill to swallow, later characterising it as (...) “the most controversial thesis of the book” (2011, p199). -/- I will argue against Sorensen’s controversial thesis and in favour of what seems to me to be a much more natural and commonsensical alternative: when we see a silhouetted object, what we see is its edge and only its edge – so we do not see its entire back-side.

In his fascinating and provocative paper, "Sharp Boundaries for Blobs," Roy Sorensen gives several arguments against the possibility of "vague objects," or objects with indeterminate boundaries.1 In what follows, I will examine the main argument given by Sorensen in his paper. This argument has a great deal of initial plausibility. Moreover, I happen to sympathize with its conclusion. Nevertheless, it seems to me that Sorensen's argument fails to establish that conclusion. The purpose of this paper is to show why. I (...) will argue that, upon careful examination, it can be seen that Sorensen's argument involves a fatal equivocation. Sorensen's argument is based on a kind of thought experiment. We are asked to consider, as a paradigm example of a vague object, a grey sphere (also known as "the blob") that fades into a white background. And we are asked to imagine a spherical cavity growing from the center of the blob, so that the growth of the cavity eventually destroys the blob. Sorensen's argument, which is explicitly spelled out in Section I of his paper, goes like this: 1. The blob must have a boundary. 2. If a spherical cavity grows from the center of the blob, the blob's outer boundary is completely unaffected as long as some of the blob remains. 3. As soon as nothing remains of the blob, the blob's boundary goes out of existence all at once. (shrink)

Abstract: Using a critical review of the literature, we study a challenge from philosophical anarchism to J. Raz's theory of legal authority: it would be irrational to follow an order with which one disagrees, since it would mean acting against what is considered more justified. Through references from decision theory and epistemology, and deploying examples about tools for assisting in routine decision-making, we sketch two possible answers: first, it may be justifiable to put yourself in a situation that leads to (...) irrationally acting; second, according to the “blindspots” theory, we outline some restrictions from a theory of rationality to the authority.

Sorensen (1992) has provided two modal-logical schemas to reconstruct the logical structure of two types of destructive thought experiments: the Necessity Refuter and the Possibility Refuter. The schemas consist of five propositions which Sorensen claims but does not prove to be inconsistent.We show that the five propositions, as presented by Sorensen, are not inconsistent, but by adding a premise (and a logical truth), we prove that the resulting sextet of premises is inconsistent. Häggqvist (2009) has provided a different modal-logical schema (...) (Counterfactual Refuter), which is equivalent to four premises, again claimed to be inconsistent. We show that this schema also is not inconsistent, for similar reasons. Again, we add another premise to achieve inconsistency. The conclusion is that all three modal-logical reconstructions of the arguments that accompany thought experiments, two by Sorensen and one by Häggqvist, have now been made rigorously correct. This may inaugurate new avenues to respond to destructive thought experiments. (shrink)

In Vagueness and Contradiction (2001), Roy Sorensen defends and extends his epistemic account of vagueness. In the process, he appeals to connections between vagueness and semantic paradox. These appeals come mainly in Chapter 11, where Sorensen offers a solution to what he calls the no-no paradox—a “neglected cousin” of the more famous liar—and attempts to use this solution as a precedent for an epistemic account of the sorites paradox. This strategy is problematic for Sorensen’s project, however, since, as we establish, (...) he fails to resolve the semantic pathology of the no-no paradox. (shrink)

Epistemicism about vagueness is the view that vagueness, or indeterminacy, is an epistemic matter. Truthmaker-gap epistemicism is the view that indeterminate truths are indeterminate because their truth is not grounded by any worldly fact. Both epistemicism in general and truthmaker-gap epistemicism originated in Roy Sorensen's work on vagueness. My aim in this paper is to give a characterization of truthmaker-gap epistemicism and argue that the view is incompatible with higher-order vagueness: vagueness in whether some case of the form ‘it is (...) determinate that A’ or ‘it is indeterminate whether A’ is true. Since it is highly likely that there is higher-order vagueness, truthmaker-gap epistemicism is in an uncomfortable position. (shrink)

In my articles ‘The Substance View: A Critique’ and ‘The Substance View: A Critique,’ I raise objections to the substance view, a theory of intrinsic value and moral standing defended by a number of contemporary moral philosophers, including Robert P.

In part one of my critique of the substance view, I raise reductio-style objections to the substance view's conclusion that the standard human fetus has the same intrinsic value and moral standing as (...) the standard adult human being, among other human beings. In part two, I raise objections to some of the premises invoked in support of that conclusion. Here, in part three, I raise objections to Henrik Friberg-Fernros's attempt to rebut some of the aforementioned objections. (shrink)

This work aims to make tense logic a more robust tool for ontologists, philosophers, knowledge engineers and programmers by outlining a fusion of tense logic and ontology of time. In order to make tense logic better understandable, the central formal primitives of standard tense logic are derived as theorems from an informal and intuitive ontology of time. In order to make formulation of temporal propositions easier, temporal operators that were introduced by Georg Henrik von Wright are developed, and mapped (...) to the ontology of time. (shrink)

Roy Sorensen introduced the concept of an epistemic blindspot in the 1980s. A proposition is an epistemic blindspot for some individual at some time if and only if that proposition is consistent but unknowable by that individual at that time. In the first half of this paper, I extend Sorensen work on blindspots by arguing that there exist blindspots that essentially involve hopes. In the second half, I show how such blindspots can contribute to and impair different pursuits of self-understanding. (...) My arguments throughout this paper draw on Luc Bovens’s account of hope.

1. Introduction: a look back at the reasons vs. causes debate. 2. The interventionist account of causation. 3. Four objections to interventionism. 4. The counterfactual analysis of event causation. 5. The role of free agency. 6. Causality in the human sciences. -- The reasons vs. causes debate reached its peak about 40 years ago. Hempel and Dray had debated the nature of historical explanation and the broader issue of whether explanations that cite an agent’s reasons are causal or not. Melden, (...) Peters, Winch, Kenny and Anscombe had contributed their anticausal conceptions. The neo-Wittgensteinians seemed to be winning the day when in 1963 Donald Davidson published his seminal paper “Actions, Reasons, and Causes”. Davidson’s paper devastated the Wittgensteinian camp. It contained, among other things, a powerful attack on the logical connection argument. Davidson argued that the existence of a logical or conceptual connection between descriptions can never eliminate a causal relation, which holds between events simpliciter, not between events under certain descriptions. Davidson maintained that in a way, reasons can be causes. When somebody acts for a certain reason, his intentional attitudes, or rather changes in his attitudes, cause his bodily movements. Davidson also argued that rationalization is a species of causal explanation. For the definition of action, he argued that intentional actions are bodily movements caused in the right way by beliefs and desires that rationalize them. Davidson’s paper paved the way for causal theories of action, which superseded neo-Wittgensteinian analyses in the following decades. The causal theory was rapidly adopted by Alvin Goldman, David Armstrong, Paul Churchland, Myles Brand and many others, entering the mainstream and dominating the philosophy of action to this very day. In 1971 Georg Henrik von Wright published his book "Explanation and Understanding". The second chapter did not deal with agency, but with causation. It developed a new account of causation, the interventionist or experimentalist account. Focusing on causation, von Wright remedied a major shortcoming of the reasons vs. causes debate. The concept of causality, and the nature of the causal relation, received little attention in this debate, a fact that holds true for both camps. Mostly it was simply taken for granted that, as Hempel had declared, “causal explanation is a special type of deductive-nomological explanation”. One camp then aligned intentional explanations with D-N explanations, while the other camp insisted on their disparity. So strictly speaking, the label “reasons/causes debate” was a misnomer. The controversy dealt primarily with the question as to whether intentional explanations can take the form of D-N explanations, while the notion of causation, and the metaphysics of the causal relation, were left obscured. With von Wright’s new approach, the situation changed. Von Wright was primarily concerned with causation, but his approach contained an implicit attack on the causal theory of action as well. His core idea was that the notion of causality is intimately linked with, or even derived from, the notion of intentionally making something happen. Other philosophers, even Hume, had considered such a connection before, but often just to reject this view, regarding it as a kind of myth belonging to the infancy of the human mind. Von Wright took the idea seriously. He submitted the analysis that p is the cause of q if and only if by doing p we could bring about q. The causal theory of action was also concerned with the relation between causation and agency, to which its name bears witness. The causal theory of action holds that actions are bodily movements with a certain causal history. This is why von Wright’s account constituted a momentous challenge to the causal theory: it reversed the direction of conceptual dependency between both notions. Davidson and his followers tried to define what an intentional action is by using the notion of causation. The causal condition which the causal theory sets is part of the definition of “doing something intentionally”. Von Wright claimed that the conceptual dependency is the other way round. He used the notions of doing, and bringing about, to explain what causal relations are. So, instead of a causal theory of action, he advocated an agency theory of causation, as it may be dubbed. It is remarkable how seldom this clash of opinions about conceptual primacy is reflected in the literature. There are few exceptions: Fred Stoutland noticed the conflict, and he published a number of papers in which he compared Davidson’s and von Wright’s views. Von Wright’s book "Explanation and Understanding" was widely read and discussed in the seventies, especially in Europe. But it strikes me that especially in North America, where the causal theory of action became the orthodoxy of the day, von Wright’s challenge went largely unnoticed. Even Davidson did not seem to take it seriously. He nowhere takes notice of the interventionist theory of causation, while he does discuss von Wright’s earlier book "Norm and Action". As is well-known, Davidson favoured an alternative account of causation, based on “the principle of the nomological character of causality”, as he somewhat clumsily called it, or, later and less clumsily, “the cause-law thesis”. Davidson’s firm adherence to a nomological theory of causality may explain why he did not take much interest in alternative accounts. [...] -/- . (shrink)

Is 'vague' vague? Is the meaning of 'true' vague? Is higher-order vagueness unavoidable? Is it possible to say precisely what it is to say something precisely? These questions, deeply interrelated and of fundamental importance to logic and semantics, have been addressed recently by Achille Varzi in articles focused on an ingenius attempt by Roy Sorensen ("An Argument for the Vagueness of 'Vague'") to demonstrate that 'vague' is vague.

Georg Henrik von Wright was not only the first interpreter of Wittgenstein, who argued that Spengler’s work had reinforced and helped Wittgenstein to articulate his view of life, but also the first to consider seriously that Wittgenstein’s attitude to his times makes him unique among the great philosophers, that the philosophical problems which Wittgenstein was struggling, indeed his view of the nature of philosophy, were somehow connected with features of our culture or civilization. -/- In this paper I draw (...) inspiration and courage from Von Wright’s insistence that trying to understand Wittgenstein in relation to his times is a philosophic task in its own right in order to probe into a relatively obscure region in Wittgenstein’s thought: his relation to the music of his times. It is a topic, on which Von Wright, and most other prominent Wittgenstein scholars, have said very little, but it is also one, which Wittgenstein himself attested was so important to him that he felt without it he was sure to be misunderstood. -/- I offer textual and historical evidence in support of my claim that, parallel to Wittgenstein’s exposure to Spengler’s Decline of the West in 1930, he was also introduced to the music theory of Heinrich Schenker, which helped him to articulate, partly by way of critique, a complex and unique position concerning the modern music of his times, which exhibits his rejection of what Von Wright later dubbed ‘the myth of progress’. As Von Wright observed in other regions of Wittgenstein’s work, he believed also with regards to the arts and to music in particular, neither in a brilliant future nor in the good old days. -/- I argue that Wittgenstein actually made a distinction between three kinds of modern music: (a) bad modern music, which is clearly a case of confusing means for ends, the hallmark of the myth of progress, as Von Wright observed; (b) vacuous modern music, which embodies some sort of diffidence, a difficulty to see through the omnipresence of what Von Wright called (following Habermas) a ‘colonialization’ of reified measures of progress; (c) good modern music, a paradoxical notion for Wittgenstein, which betokens the unlikely yet possible striving to penetrate through what appears as dissolution of the resemblances which unite this culture’s ways of life by rendering this condition as expressible and intransitively understandable. In the context of this third category, I offer an interpretation of Wittgenstein’s complex remarks on the music of Gustav Mahler, which palpably show that the problem of good modern music and the problem of philosophizing in the time of civilization were one and the same in Wittgenstein’s mind. -/- I conclude that, with regards to Von Wright’s own critical view of the modern myth of progress, we can learn from Wittgenstein that progress in the realm of art is closely aligned with the ideal of the perfection of man, yet transcending a social or political context. It is the ideal of cultural cohesion: affinity that the arts show to other human practices and cultural artifacts of its period. Wittgenstein’s tentative notion of good modern music (and its circumscription by his notion of the music of the future) may show its true colors when viewed in the context of Von Wright’s plea not to abandon work for progress as a critical task.

A number of formal epistemologists have argued that perfect rationality requires probabilistic coherence, a requirement that they often claim applies only to ideal agents. However, in “Rationality as an Absolute Concept,” Roy Sorensen contends that ‘rational’ is an absolute term. Just as Peter Unger argued that being flat requires that a surface be completely free of bumps and blemishes, Sorensen claims that being rational requires being perfectly rational. When we combine these two views, though, they lead to counterintuitive results. If (...) being rational requires being perfectly rational, and only the probabilistically coherent are perfectly rational, then this indicts all ordinary agents as irrational. In this paper, I will attempt to resolve this conflict by arguing that Sorensen is only partly correct. One important sense of ‘rational’, the sanctioning sense of ‘rational’, is an absolute term, but another important sense of ‘rational’, the sense in which someone can have rational capacities, is not. I will, then, show that this distinction has important consequences for theorizing about ideal rationality, developing an account of the relationship between ordinary and ideal rationality. Because the sanctioning sense of ‘rational’ is absolute, it is rationally required to adopt the most rational attitude available, but which attitude is most rational can change depending on whether we are dealing with ideal agents or people more like ourselves.

Instability occurs when the very fact of choosing one particular possible option rather than another affects the expected values of those possible options. In decision theory: An act is stable iff given that it is actually performed, its expected utility is maximal. When there is no stable choice available, the resulting instability can seem to pose a dilemma of practical rationality. A structurally very similar kind of instability, which occurs in cases of anti-expertise, can likewise seem to create dilemmas of (...) epistemic rationality. One possible line of response to such cases of instability, suggested by both Jeffrey (1983) and Sorensen (1987), is to insist that a rational agent can simply refuse to accept that such instability applies to herself in the first place. According to this line of thought it can be rational for a subject to discount even very strong empirical evidence that the anti-expertise condition obtains. I present a new variety of anti-expertise condition where no particular empirical stage-setting is required, since the subject can deduce a priori that an anti-expertise condition obtains. This kind of anti-expertise case is therefore not amenable to the line of response that Jeffrey and Sorensen recommend. (shrink)

It is commonly assumed that blameworthiness is epistemically constrained. If one lacks sufficient epistemic access to the fact that some action harms another, then one cannot be blamed for harming. Acceptance of an epistemic condition for blameworthiness can give rise to a worry, however: could agents ever successfully evade blameworthiness by deliberately stunting their epistemic position? I discuss a particularly worrisome version of such epistemic shirking, in which agents pre-emptively seek to avoid access to potentially morally relevant facts. As Roy (...) Sorensen and Jan Willem Wieland have argued, we seem to be faced with a potentially troubling regress when trying to explain what goes wrong in such situations. I argue that the solution to this so-called Shirker Problem is not to be found in complicated and demanding anti-shirking-principles with universal scope and potentially self-reflexive content. Instead, careful consideration of the necessary motivational make-up of genuine shirkers reveals their ignorance to lack the necessary depth to be exculpatory. Since shirkers by definition react to the possibility of the revelation of morally relevant facts with acts of epistemic self-limitation, they necessarily prove guilty of a form of culpable moral recklessness. Epistemic shirking thus does not pose a worrisome problem for ethical theory. (shrink)

Rush Rhees, Georg Henrik von Wright and Elizabeth Anscombe are well known as the literary executors who made Ludwig Wittgenstein’s later philosophy available to all interested readers. Their editions of Wittgenstein’s writings have become an integral part of the modern philosophical canon. However, surprisingly little is known about the circumstances and reasons that made Wittgenstein choose them to edit and publish his papers. This essay sheds light on these questions by presenting the story of their personal relationships—relationships that, on (...) the one hand, gave Rhees, von Wright and Anscombe distinct insights into Wittgenstein’s philosophizing; and, on the other hand, let Wittgenstein assume that these three former students, and later colleagues and friends, were the most capable of preparing his work for publication. Using hitherto unpublished archival material as well as information from published recollections, the essay sketches the development of the personal and philosophical bonds from which the literary heirs’ distinct ways of handling Wittgenstein’s unpublished writings grew in later years.

The chapter examines fifty years of philosophers working on lying - from the 1970s to the current day – focusing on how lying is defined (descriptively and normatively), whether lying involves an intention to deceive (Deceptionists) or not (Non-Deceptionists), why lying is wrong, and whether lying is worse than other forms of deception, including misleading with the truth. Philosophers discussed include Roderick Chisholm and Thomas Feehan, Alan Donagan, Sissela Boy, Charles Fried, David Simpson, David Simpson, Bernard Williams, Paul Faulkner, Thomas (...) Carson, Roy Sorensen, Don Fallis, Jennifer Saul, Andreas Stoke, Jonathan Webber and Clea Rees. (shrink)
