David Enoch recently defended the idea that there are valid inferences of the form ‘it would be good if p, therefore, p’. I argue that Enoch's proposal allows us to infer the absurd conclusion that ours is the best of all possible worlds.

There are two distinct views on how to formulate an objective consequentialist account of the deontic status of actions, actualism and possibilism. On an actualist account, what matters to the deontic status of actions is only the value of the outcome an action would have, if performed. By contrast, a possibilist account also takes into account the value of the outcomes that an action could have. These two views come apart in their deontic verdicts when an agent is imperfect in (...) an avoidable way, viz., when agent brings about less good than she could. In this paper, I offer an argument against actualism that draws on the connection between moral obligation and practical reasons. (shrink)

Some moral theories, such as objective forms of consequentialism, seem to fail to be practically useful: they are of little to no help in trying to decide what to do. Even if we do not think this constitutes a fatal flaw in such theories, we may nonetheless agree that being practically useful does make a moral theory a better theory, or so some have suggested. In this paper, I assess whether the uncontroversial respect in which a moral theory can be (...) claimed to be better if it is practically useful can provide a ground worth taking into account for believing one theory rather than another. I argue that this is not the case. The upshot is that if there is a sound objection to theories such as objective consequentialism that is based on considerations of practical usefulness, the objection requires that it is established that the truth about what we morally ought to do cannot be epistemically inaccessible to us. The value of practical usefulness has no bearing on the issue. (shrink)

This article addresses the fiduciary issues raised by the current practice of plan fiduciaries of not only disclaiming any fiduciary responsibility for brokerage window investments, but also abdicating any role (fiduciary or otherwise) in assessing even the general suitability of those investments for a retirement plan, and concludes that the practice is in plain and notorious violation of what ERISA requires of fiduciaries.

Under a policy first enacted in 1988 and expanded in 1996, federally funded public housing authorities (“PHAs”) and private landlords renting their properties to tenants receiving federal housing assistance have been required to include a provision in all leases under which drug-related criminal activity as well as criminal activity that in any way poses a threat to other tenants or nearby residents constitutes ground for initiating eviction proceedings. This strict liability eviction policy, which has become known as the “One-Strike Rule,” (...) was part of a broader congressional effort to combat the “reign of terror” that Congress believed drug dealers were imposing on public housing and assisted housing tenants. Like many of the crime-related policies enacted in the 1980s and 1990s, the One-Strike Rule has done little to reduce crime rates, but has been wildly successful in ensuring that the situation of poor households receiving federal assistance remains highly precarious. Calls for reform of the One-Strike Rule are almost as old as the policy itself, but given the political outlook of the current administration, the prospects for reform at the federal level are dim. While federal law and a combination of gridlock and unwillingness in the congressional and executive branches foreclose a range of possible strategies for reform, there is nonetheless room to mitigate the socially corrosive effects of the One-Strike Rule through legislative efforts at the state and local level. Courts in various jurisdictions have upheld state laws that protect vulnerable tenants despite the federal strict liability policy, and these holdings help to provide a framework for how state and local governments seeking to protect tenants can do so without their efforts necessarily falling prey to the Supremacy Clause. This article describes that framework and proposes three concrete measures that fit it. The article is structured as follows: after explaining the One-Strike Rule and the threat it poses to vulnerable tenants (Section II), the article discusses the burden the Rule imposes on tenants and the benefits it is supposed to bring to other parties, and argues that the resulting distribution of burdens and benefits is unjust (Section III). The article then lays out three concrete measures that state and local governments can enact to protect tenants who face eviction for criminal activity under the Rule without falling prey to a federal preemption challenge: requiring “good cause” for eviction, giving tenants the right to cure a breach of their lease, and providing tenants with free counsel in landlord-tenant court (Section IV).

In its recent opinion in Intel v. Sulyma, the U.S. Supreme Court clarified what qualifies as the “actual knowledge” required to trigger ERISA’s three-year statutory period. The Court’s opinion, however, left open whether establishing “actual knowledge” by a plaintiff in one case serves to time-bar otherwise timely suits that challenge subsequent breaches of the same character. This article argues that, under the continuing fiduciary duty analysis that the Court set forth in Tibble v. Edison, such suits should not be deemed (...) untimely. (shrink)

The characterization of objective, normative reasons to φ as facts (or truths) that count in favor of φ-ing is widely accepted. But are there any further conditions that considerations which count in favor of φ-ing must meet, in order to count as a reason to φ? In this brief paper, I consider and reject one such condition, recently proposed by Caspar Hare.

According to the principle that ‘ought’ implies ‘can’, it is never the case that you ought to do something you cannot do. While many accept this principle in some form, it also has its share of critics, and thus it seems desirable if an argument can be offered in its support. The aim of this paper is to examine a particular way in which the principle has been defended, namely, by appeal to considerations of fairness. In a nutshell, the idea (...) (due to David Copp) is that moral requirements we cannot comply with would be unfair, and there cannot be unfair moral requirements. I discuss several ways of spelling out the argument, and argue that all are unsatisfactory for a variety of reasons. (shrink)

Many philosophers think the distinctive function of deontic evaluation is to guide action. This idea is used in arguments for a range of substantive claims. In this paper, we entirely do one completely destructive thing and partly do one not entirely constructive thing. The first thing: we argue that there is an unrecognized gap between the claim that the function of deontic evaluation is to guide action and attempts to put that claim to use. We consider and reject four arguments (...) intended to bridge this gap. The interim conclusion is thus that arguments starting with the claim that the function of deontic evaluation is to guide action have a lacuna. The second thing: we consider a different tack for making arguments of this sort work. We sketch a methodology one could accept that would do the trick. Unfortunately, as we’ll explain, although this methodology would bridge the gap in arguments that put claims about the function of deontic evaluation to work, it would do so in a way that vitiates any interest we might have in such arguments. As an aside, we’ll also point out how epistemologists, who have recently become interested in the function of epistemic evaluation, appear to already recognize this fact. The conclusion is hence a dilemma: either arguments from deontic function to substance have a lacuna or such arguments lack teeth. (shrink)

In dit artikel wordt de dominante metafysische oriëntatie in de hedendaagse meta-ethiek kritisch onder de loep genomen. Het hedendaagse debat, dat zich voornamelijk richt op de vraag hoe moraliteit metafysisch gezien 'in de werkelijkheid past', wordt gekenmerkt door een reeks complexe en soms esoterische discussies die, zo wordt betoogd, weinig bijdragen aan ons filosofische begrip van ethiek. Deze focus op metafysische grondslagen heeft geleid tot een tunnelvisie, waarin het debat gevangen zit tussen steeds ingewikkeldere vormen van non-cognitivisme, herconceptualisaties van 'objectiviteit' (...) en metafysische acrobatiek. Als alternatief wordt voorgesteld de aandacht in de meta-ethiek te verleggen naar het domein van praktisch redeneren. Door ons te concentreren op de patronen van geldige praktische argumentatie en het soort overwegingen dat mensen daadwerkelijk overtuigt, kunnen we wellicht een beter inzicht krijgen in de aard van ethische normativiteit en de rol ervan in ons leven. Het artikel pleit voor een meer pragmatische en minder metafysisch beladen benadering van de meta-ethiek, die zich richt op de daadwerkelijke praktijken van moreel redeneren en argumenteren.

Central to many discussions of motivated reasoning is the idea that it runs afoul of epistemic normativity. Reasoning differently about information supporting our prior beliefs versus information contradicting those beliefs, is frequently equated with motivated irrationality. By analyzing the normative status of belief polarization, selective scrutiny, biased assimilation and the myside bias, I show this inference is often not adequately supported. Contrary to what’s often assumed, these phenomena need not indicate motivated irrationality, even though they are instances of belief-consistent information (...) processing. Second, I engage with arguments purporting to show that belief-consistent information processing does not indicate motivated irrationality because of its mere differential treatment of confirming and non-confirming evidence, but rather because it reveals the undermining presence of an irrelevant influence, such as a desire or partisan identity-driven cognition. While linking belief-consistent reasoning to a deeper source of directional motivation to make good on the claim that it indicates motivated irrationality is indeed what’s needed, two prominent such arguments fail. The non-normativity of many reasoning processes often taken to indicate motivated irrationality is not in fact well established. (shrink)

The debate on whether and why misinformation is bad primarily focuses on the spread of false beliefs as its main harm. From the assumption that misinformation primarily causes harm through the spread of false beliefs as a starting point, it has been contended that the problem of misinformation has been exaggerated. Its tendency to generate false beliefs appears to be limited. However, the near-exclusive focus on whether or not misinformation dupes people with false beliefs neglects other epistemic harms associated with (...) it. Specifically, I show that misinformation also causes trouble for the epistemic goods of truth attainment, intellectual autonomy and debate pluriformity. Moreover, for each of these goods, I argue that emphasizing error-avoidance exacerbates, rather than mitigates, the harms caused by misinformation. These oversights and dilemmas show that prioritizing error-avoidance in the fight against misinformation is not a neutral default policy or necessarily a net positive. A shift in focus away from the spread of false beliefs as the main harm of misinformation is needed to better understand and counter its negative effects. (shrink)

Galileo proposed what has been called a proto-inertial principle, according to which a body un horizontal motion will conserve its motion. This statement is only true in counterfactual circumstances where no impediments are present. This paper analyzes how Galileo could have been justified in ascribing definite properties to this idealized motion. This analysis is then used to better understand the relation of Galileo’s proto-inertial principle to the classical inertial principle.

It is argued that, contrary to prevailing opinion, Bas van Fraassen nowhere uses the argument from underdetermination in his argument for constructive empiricism. It is explained that van Fraassen’s use of the notion of empirical equivalence in The Scientific Image has been widely misunderstood. A reconstruction of the main arguments for constructive empiricism is offered, showing how the passages that have been taken to be part of an appeal to the argument from underdetermination should actually be interpreted.

I show why Michael Friedman’s idea that we should view new constitutive frameworks introduced in paradigm change as members of a convergent series introduces an uncomfortable tension in his views. It cannot be justified on realist grounds, as this would compromise his Kantian perspective, but his own appeal to a Kantian regulative ideal of reason cannot do the job either. I then explain a way to make better sense of the rationality of paradigm change on what I take to be (...) Friedman’s own terms. (shrink)

Recent years saw the rise of an interest in the roles and significance of thought experiments in different areas of human thinking. Heisenberg's gamma ray microscope is no doubt one of the most famous examples of a thought experiment in physics. Nevertheless, this particular thought experiment has not received much detailed attention in the philosophical literature on thought experiments up to date, maybe because of its often claimed inadequacies. In this paper, I try to do two things: to provide an (...) interesting interpretation of the roles played by Heisenberg's gamma ray microscope in interpreting quantum mechanics – partly based on Thomas Kuhn’s views on the function of thought experiments – and to contribute to the ongoing discussions on the roles and significance of thought experiments in physics.

How Galileo Galilei discovered the law of fall, and the difference that this makes Galileo’s law of fall is one of the crucial building blocks of classical mechanics. The question how this law was discovered has often been a topic of debate. This article offers a reconstruction of the developments within Galileo’s research that led to the discovery of the law. This reconstruction is offered to make a philosophical point regarding the epistemic status of experimental results: Galileo’s experiments can offer (...) sufficient justification for the acceptance of the law of fall only because of their place in a broad research programme.

In dit artikel betwist ik het gangbare idee dat de rede ontoereikend is voor morele motivatie, met name in relatie tot universele ethische kwesties. Door een uitgebreide verkenning van de Dual-Process Theory (DPT) stel ik dat onze morele intuïties zowel trainbaar zijn als een inherente neiging hebben naar universalistische overwegingen. Ik betoog dat sociale rechtvaardiging en de drang naar rationele argumentatie een cruciale rol spelen in het vormen en veranderen van onze morele standpunten. Concluderend pleit ik voor een herwaardering van (...) klassiek moreel redeneren en stel ik dat een universele ethiek psychologisch realistischer is dan eerder werd aangenomen. (shrink)

Starting with a discussion of what I call Koyré’s paradox of conceptual novelty, I introduce the ideas of Damerow et al. on the establishment of classical mechanics in Galileo’s work. I then argue that although the view of Damerow et al. on the nature of Galileo’s conceptual innovation is convincing, it misses an essential element: Galileo’s use of the experiments described in the first day of the Two New Sciences. I describe these experiments and analyze their function. Central to my (...) analysis is the idea that Galileo’s pendulum experiments serve to secure the reference of his theoretical models in actually occurring cases of free fall. In this way Galileo’s experiments constitute an essential part of the meaning of the new concepts of classical mechanics. (shrink)

In this paper I challenge Paolo Palmieri’s reading of the Mach-Vailati debate on Archimedes’s proof of the law of the lever. I argue that the actual import of the debate concerns the possible epistemic (as opposed to merely pragmatic) role of mathematical arguments in empirical physics, and that construed in this light Vailati carries the upper hand. This claim is defended by showing that Archimedes’s proof of the law of the lever is not a way of appealing to a non-empirical (...) source of information, but a way of explicating the mathematical structure that can represent the empirical information at our disposal in the most general way.

The introduction of laws of nature is often seen as one of the hallmarks of the Scientific Revolution of the seventeenth century. The new sciences are thought to have introduced the revolutionary idea that explanations of natural phenomena have to be grounded in exceptionless regularities of universal scope, i. e. laws of nature. The use of legal terminology to talk about natural regularities has a longer history, though. This article traces these earlier uses.

Horology refers to the measurement of time, as well as the art of building instruments with which to study and measure time. There were two important developments in the early modern period: the dramatic improvement of the quality of mechanical clocks due to highly skilled craftsmen, and the introduction of the pendulum as time-keeper in the escapement mechanism. The latter innovation not only allowed a further jump in precision, it also had important conceptual implications.

Akin to the mathematical recreations, John Wilkins' Mathematicall Magick (1648) elaborates the pleasant, useful and wondrous part of practical mathematics, dealing in particular with its material culture of machines and instruments. We contextualize the Mathematicall Magick by studying its institutional setting and its place within changing conceptions of art, nature, religion and mathematics. We devote special attention to the way Wilkins inscribes mechanical innovations within a discourse of wonder. Instead of treating ‘wonder’ as a monolithic category, we present a typology, (...) showing that wonders were not only recreative, but were meant to inspire Wilkins' readers to new mathematical inventions.

The falsity of moral claims is commonly deduced from two tenets: that they presuppose the existence of objective values and that these values don’t exist. Hence, the error theory concludes, moral claims are false. In this article, I put pressure on the image of human morality that is presupposed in moving from the non-existence of objective values to the falsity of moral claims. I argue that, while, understood in a certain way, the two premises of the error theory are correct, (...) this does not render moral discourse false, because moral objectivity is disanalogous to objectivity in empirical sciences and as such need not be characterized in terms of mind-independency. Using Dewey, I illuminate the possibility of accommodating the guiding intuitions of the error theory in a first-order account of morality. (shrink)

Equipped with the ultimate query answering system, computers would finally be in a position to address all our information needs in a natural way. In this paper, we describe how Language and Computing nv (L&C), a developer of ontology-based natural language understanding systems for the healthcare domain, is working towards the ultimate Question Answering (QA) System for healthcare workers. L&C’s company strategy in this area is to design in a step-by-step fashion the essential components of such a system, each component (...) being designed to solve some one part of the total problem and at the same time reflect well-defined needs on the prat of our customers. We compare our strategy with the research roadmap proposed by the Question Answering Committee of the National Institute of Standards and Technology (NIST), paying special attention to the role of ontology.

The concept of impetus denoted the transmission of a power from the mover to the object moved. Many authors resorted to this concept to explain why a projectile keeps on moving when no longer in contact with its initial mover. But its application went further, as impetus was also appealed to in attempts to explain the acceleration of falling bodies or the motion of the heavens. It was widely applied in Renaissance natural philosophy, but it also raised a number of (...) ontological questions concerning its precise nature. (shrink)

Toon van Eijk: Spinoza in het licht van bewustzijnsontwikkeling De beroemde filosoof Spinoza is moeilijk te doorgronden. Emeritus hoogleraar Maarten van Buuren heeft in 2016 twee boeken over Spinoza gepubliceerd, waarin hij diens filosofie op nauwgezette en verhelderende manier analyseert. Volgens Van Buuren is de kern van Spinoza’s ethiek de bevrijding van bevoogding en het streven om in overeenstemming te leven met de wereld en met zichzelf. Een aantal sleutelbegrippen in Spinoza’s filosofie zijn de immanente, in de natuur-inwonende God, (...) zelfbeschikking, de rede, intuïtie, macht en zelftoe-eigening. In dit boek bespreekt Toon van Eijk deze sleutelbegrippen aan de hand van de analyse van Van Buuren en de filosofie van Maharishi Mahesh Yogi, de grondlegger van de Transcendente Meditatie (TM) techniek. Filosofische begrippen blijven echter tandeloos zonder mogelijkheden om deze ideeën te verwerkelijken. Een synthese van filosofisch redeneren en praktijken voor bewustzijnsontwikkeling is nodig. Hoewel Spinoza een ethiek zonder metafysica voorstond, is Van Eijk van mening dat daadwerkelijk wijs handelen moeilijk zonder enige metafysische bagage kan. (shrink)

In a previous issue of Tijdschrift voor Filosofie, Filip Buekens argues that evolutionary psychology (EP), or some interpretations thereof, have a corrosive impact on our ‘manifest self-image’. Buekens wants to defend and protect the global adequacy of this manifest self-image in the face of what he calls evolutionary revisionism. Although we largely agree with Buekens’ central argument, we criticize his analysis on several accounts, making some constructive proposals to strengthen his case. First, Buekens’ argument fails to target EP, because his (...) notion of the ‘constitutive conditions’ of our attitudes is too wide and too extensive. Second, his defense of the global adequacy of our attitudes does not allow for sufficient differentiation to analyze the problem of potential self-refutation with respect to EP. Third, his account of knowledge about constitutive conditions, and its impact on our self-image, is problematic. We provide a more detailed explanation for the pervasiveness of evolutionary revisionism and other misconceptions about EP. Finally, we consider in what sense EP may legitimately affect our self-image, and whether it can truly inspire corrections of our view of human nature. (shrink)

In a recent paper, Nate Sharadin and Rob van Someren Greve pull into doubt a seemingly platitudinous idea: deontic evaluation is capable of guiding action (“Capable”). After discussing several arguments for it, the authors conclude that, to the extent to which Capable can be defended, it cannot produce interesting results about the nature of the deontic. My goal is to argue that the authors’ skeptical endeavors are unconvincing. I aim to show that they rely on an implausibly broad understanding (...) of “actual guidance”. I propose an alternative understanding and show that, with it, “functionalist” arguments of the above kind can produce interesting results. If I am right, Sharadin’s and van Someren Greve’s considerations do not get off the ground. Instead, optimism seems warranted: We can learn something interesting about the nature of the deontic by assuming that actual guidance is the function of deontic evaluation. (shrink)

The theories of belief change developed within the AGM-tradition are not logics in the proper sense, but rather informal axiomatic theories of belief change. Instead of characterizing the models of belief and belief change in a formalized object language, the AGM-approach uses a natural language — ordinary mathematical English — to characterize the mathematical structures that are under study. Recently, however, various authors such as Johan van Benthem and Maarten de Rijke have suggested representing doxastic change within a formal (...) logical language: a dynamic modal logic. Inspired by these suggestions Krister Segerberg has developed a very general logical framework for reasoning about doxastic change: dynamic doxastic logic (DDL). This framework may be seen as an extension of standard Hintikka-style doxastic logic with dynamic operators representing various kinds of transformations of the agent's doxastic state. Basic DDL describes an agent that has opinions about the external world and an ability to change these opinions in the light of new information. Such an agent is non-introspective in the sense that he lacks opinions about his own belief states. Here we are going to discuss various possibilities for developing a dynamic doxastic logic for introspective agents: full DDL or DDL unlimited. The project of constructing such a logic is faced with difficulties due to the fact that the agent’s own doxastic state now becomes a part of the reality that he is trying to explore: when an introspective agent learns more about the world, then the reality he holds beliefs about undergoes a change. But then his introspective (higher-order) beliefs have to be adjusted accordingly. In the paper we shall consider various ways of solving this problem. (shrink)

Relationalism maintains that perceptual experience involves, as part of its nature, a distinctive kind of conscious perceptual relation between a subject of experience and an object of experience. Together with the claim that perceptual experience is presentational, relationalism is widely believed to be a core aspect of the naive realist outlook on perception. This is a mistake. I argue that naive realism about perception can be upheld without a commitment to relationalism.

Philosophers of science have given up on the quest for a silver bullet to put an end to all pseudoscience, as such a neat formal criterion to separate good science from its contenders has proven elusive. In the literature on critical thinking and in some philosophical quarters, however, this search for silver bullets lives on in the taxonomies of fallacies. The attractive idea is to have a handy list of abstract definitions or argumentation schemes, on the basis of which one (...) can identify bad or invalid types of reasoning, abstracting away from the specific content and dialectical context. Such shortcuts for debunking arguments are tempting, but alas, the promise is hardly if ever fulfilled. Different strands of research on the pragmatics of argumentation, probabilistic reasoning and ecological rationality have shown that almost every known type of fallacy is a close neighbor to sound inferences or acceptable moves in a debate. Nonetheless, the kernel idea of a fallacy as an erroneous type of argument is still retained by most authors. We outline a destructive dilemma we refer to as the Fallacy Fork: on the one hand, if fallacies are construed as demonstrably invalid form of reasoning, then they have very limited applicability in real life. On the other hand, if our definitions of fallacies are sophisticated enough to capture real-life complexities, they can no longer be held up as an effective tool for discriminating good and bad forms of reasoning. As we bring our schematic “fallacies” in touch with reality, we seem to lose grip on normative questions. Even approaches that do not rely on argumentation schemes to identify fallacies fail to escape the Fallacy Fork, and run up against their own version of it. (shrink)
