The best arguments for possible worlds as states of affairs furnish us with equally good arguments for impossible worlds of the same sort. I argue for a theory of impossible worlds on which the impossible worlds correspond to maximal inconsistent classes of propositions. Three objections are rejected. In the final part of the paper, I present a menu of impossible worlds and explore some of their interesting formal properties.

Several themes of David Lewis's theory of counterfactuals, especially their sensitivity to context, pave the way for a viable theory of non-trivial counterpossibles. If Lewis was successful in defending his account against the early objections, a semantics of counterpossibles can be defended from similar objections in the same way. The resulting theory will be extended to address 'might' counterfactuals and questions about the relative "nearness" of impossible worlds.

Whether certain objects compose a whole at a given time does not seem to depend on anything other than the character of those objects and the relations between them. This observation suggests a far-reaching constraint on theories of composition. One version of the constraint has been explicitly adopted by van Inwagen and rules out his own answer to the composition question. The constraint also rules out the other well-known moderate answers that have so far been proposed.

A recently advanced argument for purgatory hinges on the need for complete sanctification before one can enter heaven. The argument has a modal gap.The gap can be exploited to fashion a competing account of how sanctification occurs in the afterlife according to which it is in part a heavenly process.The competing account usefully complicates the overall case for purgatory and raises questions about how the notion ought to be understood.

Plausibly, no agent ever performs an action without some desire to perform that action. If so, a regress argument shows that, given incompatibilism, we are only rarely free. The argument sidesteps recent objections to this thesis.

Plausibly, if an object persists through time, then its later existence must be caused by its earlier existence. Many theists endorse a theory of continuous creation, according to which God is the sole cause of a creature's existence at a given time. The conjunction of these two theses rather unfortunately implies that no object distinct from God persists at all. What strategies for resolving this difficulty are available?

Judgments of blame for others are typically sensitive to what an agent knows and desires. However, when people act negligently, they do not know what they are doing and do not desire the outcomes of their negligence. How, then, do people attribute blame for negligent wrongdoing? We propose that people attribute blame for negligent wrongdoing based on perceived mental control, or the degree to which an agent guides their thoughts and attention over time. To acquire information about others’ mental control, (...) people self-project their own perceived mental control to anchor third-personal judgments about mental control and concomitant responsibility for negligent wrongdoing. In four experiments (N = 841), we tested whether perceptions of mental control drive third-personal judgments of blame for negligent wrongdoing. Study 1 showed that the ease with which people can counterfactually imagine an individual being non-negligent mediated the relationship between judgments of control and blame. Studies 2a and 2b indicated that perceived mental control has a strong effect on judgments of blame for negligent wrongdoing and that first-personal judgments of mental control are moderately correlated with third-personal judgments of blame for negligent wrongdoing. Finally, we used an autobiographical memory manipulation in Study 3 to make personal episodes of forgetfulness salient. Participants for whom past personal episodes of forgetfulness were made salient judged negligent wrongdoers less harshly compared to a control group for whom past episodes of negligence were not salient. Collectively, these findings suggest that first-personal judgments of mental control drive third-personal judgments of blame for negligent wrongdoing and indicate a novel role for counterfactual thinking in the attribution of responsibility.

This paper discusses three relevant logics that obey Component Homogeneity - a principle that Goddard and Routley introduce in their project of a logic of significance. The paper establishes two main results. First, it establishes a general characterization result for two families of logic that obey Component Homogeneity - that is, we provide a set of necessary and sufficient conditions for their consequence relations. From this, we derive characterization results for S*fde, dS*fde, crossS*fde. Second, the paper establishes complete sequent calculi (...) for S*fde, dS*fde, crossS*fde. Among the other accomplishments of the paper, we generalize the semantics from Bochvar, Hallden, Deutsch and Daniels, we provide a general recipe to define containment logics, we explore the single-premise/single-conclusion fragment of S*fde, dS*fde, crossS*fdeand the connections between crossS*fde and the logic Eq of equality by Epstein. Also, we present S*fde as a relevant logic of meaninglessness that follows the main philosophical tenets of Goddard and Routley, and we briefly examine three further systems that are closely related to our main logics. Finally, we discuss Routley's criticism to containment logic in light of our results, and overview some open issues. (shrink)

The theory of possible worlds has permeated analytic philosophy in recent decades, and its best versions have a consequence which has gone largely unnoticed: in addition to the panoply of possible worlds, there are a great many impossible worlds. A uniform ontological method alone should bring the friends of possible worlds to adopt impossible worlds, I argue, but the theory's applications also provide strong incentives. In particular, the theory facilitates an account of counterfactuals which avoids several of the implausible results (...) of David Lewis's account, and it paves the way for the analogues of Kripkean semantics for epistemic and relevant logics. On the theories of possible worlds as abstract objects, worlds bear a strong resemblance to propositions. I contend that if there are distinct necessarily false propositions, then there are likewise distinct impossible worlds. However, one who regards possible worlds as concrete objects must not recognize impossible worlds, in part because concrete worlds cannot misrepresent certain features of reality, as some impossible worlds must. Accordingly, I defend and develop a theory of impossible worlds as maximal impossible states of affairs. Impossible worlds perform admirably in the analysis of counterfactuals with impossible antecedents. I argue that, contrary to standard accounts, not all counterpossibles are trivially true, and I develop a Lewis-style semantics which allows this result. The point is crucial, since many views presuppose that some counterpossibles are substantive philosophical truths. Finally, I show that impossible worlds hold great promise for doxastic and relevant logics. Epistemic logic needs a domain of propositions which is not closed under strict implication to avoid the problem of logical omniscience, and relevant logic needs such a domain to avoid the famous paradoxes of implication. In sum, impossible world theory promises natural, elegant solutions to philosophical problems in numerous areas where possible worlds alone flounder. These solutions come to most possible world theorists at no cost, since the existence of impossible worlds is entailed by theses they already hold. (shrink)

Felix Klein and Abraham Fraenkel each formulated a criterion for a theory of infinitesimals to be successful, in terms of the feasibility of implementation of the Mean Value Theorem. We explore the evolution of the idea over the past century, and the role of Abraham Robinson's framework therein.

Drugs used to provide improvement of cognitive functioning have been shown to be effective in healthy individuals. It is sometimes assumed that the use of these drugs constitutes cheating in an academic context. We examine whether this assumption is ethically sound. Beyond providing the most up-to-date discussion of modafinil use in an academic context, this contribution includes an overview of the safety of modafinil use in greater depth than previous studies addressing the issue of cheating. Secondly, we emphasize two crucial, (...) but hitherto nearly overlooked, nuances to the issues: the potential for modafinil to decrease inequality and disadvantage in academic settings, and the fact that how modafinil is used dramatically impacts its effects on health, coercion, fairness, authenticity and effort. Finally, we explicitly defend the position that there are no qualitatively morally relevant differences between modafinil use and other enhancement modalities; any such differences are in degree,...

The work of Thomas White represents a systematic attempt to combine the best of the new science of the seventeenth century with the best of Aristotelian tradition. This attempt earned him the criticism of Hobbes and the praise of Leibniz, but today, most of his attempts to navigate between traditions remain to be explored in detail. This paper does so for his ontology of accidents. It argues that his criticism of accidents in the category of location as entities over (...) and above substances was likely aimed at Francisco Suárez, and shows how White’s worries about the analysis of location were linked with his broader cosmological views. White rejects real qualities, but holds that the quantity of a substance is somehow distinct from its bearer. This reveals a common ground with some of his scholastic interlocutors, but lays bare a deep disagreement with thinkers like Descartes on the nature of matter. (shrink)

Summary: Edward Lanphier and colleagues contend that human germline editing is an unethical technology because it could have unpredictable effects on future generations. In our view, such misgivings do not justify their proposed moratorium.

Principles of procreative beneficence (PPBs) hold that parents have good reasons to select the child with the best life prospects. Sparrow (2010) claims that PPBs imply that we should select only female children, unlesswe attach normative significance to “normal” human capacities. We argue that this claim fails on both empirical and logical grounds. Empirically, Sparrow’s argument for greater female wellbeing rests on a selective reading of the evidence and the incorrect assumption that an advantage for females would persist even when (...) a serious gender imbalance is obtained. Logically, PPBs cite only pro tanto reasons and allow that the good of an individual child could be outweighed by other morally relevant considerations, such as those which take collectively suboptimal outcomes into account. There is thus no need to attach value to the “normal.”. (shrink)

The translational research community, in general, and the Clinical and Translational Science Awards (CTSA) community, in particular, share the vision of repurposing EHRs for research that will improve the quality of clinical practice. Many members of these communities are also aware that electronic health records (EHRs) suffer limitations of data becoming poorly structured, biased, and unusable out of original context. This creates obstacles to the continuity of care, utility, quality improvement, and translational research. Analogous limitations to sharing objective data in (...) other areas of the natural sciences have been successfully overcome by developing and using common ontologies. This White Paper presents the authors’ rationale for the use of ontologies with computable semantics for the improvement of clinical data quality and EHR usability formulated for researchers with a stake in clinical and translational science and who are advocates for the use of information technology in medicine but at the same time are concerned by current major shortfalls. This White Paper outlines pitfalls, opportunities, and solutions and recommends increased investment in research and development of ontologies with computable semantics for a new generation of EHRs.

Is it possible for an individual that has gone out of being to come back into being again? The English Aristotelian, Thomas White, argued that it is not. Thomas Hobbes disagreed, and used the case of the Ship of Theseus to argue that individuals that have gone out of being may come back into being again. This paper provides the first systematic account of their arguments. It is doubtful that Hobbes has a consistent case against White. Still his (...) criticism may have prompted White to clarify his views on identity over time in his later work. (shrink)

To explore the extent of embeddability of Leibnizian infinitesimal calculus in first-order logic (FOL) and modern frameworks, we propose to set aside ontological issues and focus on pro- cedural questions. This would enable an account of Leibnizian procedures in a framework limited to FOL with a small number of additional ingredients such as the relation of infinite proximity. If, as we argue here, first order logic is indeed suitable for developing modern proxies for the inferential moves found in Leibnizian infinitesimal (...) calculus, then modern infinitesimal frameworks are more appropriate to interpreting Leibnizian infinitesimal calculus than modern Weierstrassian ones.

While several tests and strategies are recommended for colorectal cancer (CRC) screening, studies suggest that primary care providers often recommend colonoscopy without providing information about its risks or alternatives.

[ROYAL INSTITUTE OF PHILOSOPHY 2023 ESSAY PRIZE WINNER] I argue that the term ‘naturalism’ is so empty of meaning that it is not suitable for serious theorizing in philosophy. In particular, I argue that the question of whether or not some theory or thesis should count as naturalistic is an empty verbal dispute with no further theoretical significance. I also discuss naturalism construed as a methodological thesis and argue that any plausible version will collapse into triviality. Lastly, I briefly discuss (...) the idea that naturalism is not a thesis at all but rather a ‘stance’ and suggest that this too succumbs to the charge of emptiness. I conclude that we should stop talking about naturalism altogether. (shrink)

A good account of the agnostic attitude of Suspending Judgement should explain how it can be rendered more or less rational/justified according to the state of one's evidence – and one's relation to that evidence. I argue that the attitude of suspending judgement whether p constitutively involves having a belief; roughly, a belief that one cannot yet tell whether or not p. I show that a theory of suspending that treats it as a sui generis attitude, wholly distinct from belief, (...) struggles to account for how suspension of judgement can be rendered more or less rational (or irrational) by one's evidence. I also criticise the related idea that suspension essentially requires an 'Inquiring Attitude'. I show how a belief-based theory, in contrast, neatly accounts for the rational and epistemic features of suspending and so neatly accounts for why an agnostic has a genuine neutral opinion concerning the question whether p, as opposed to simply having no opinion.

A key source of support for the view that challenging people’s beliefs about free will may undermine moral behavior is two classic studies by Vohs and Schooler (2008). These authors reported that exposure to certain prompts suggesting that free will is an illusion increased cheating behavior. In the present paper, we report several attempts to replicate this influential and widely cited work. Over a series of five studies (sample sizes of N = 162, N = 283, N = 268, N (...) = 804, N = 982) (four preregistered) we tested the relationship between (1) anti-free-will prompts and free will beliefs and (2) free will beliefs and immoral behavior. Our primary task was to closely replicate the findings from Vohs and Schooler (2008) using the same or highly similar manipulations and measurements as the ones used in their original studies. Our efforts were largely unsuccessful. We suggest that manipulating free will beliefs in a robust way is more difficult than has been implied by prior work, and that the proposed link with immoral behavior may not be as consistent as previous work suggests.

A growing number of decision theorists have, in recent years, defended the view that rationality is permissive under risk: Different rational agents may be more or less risk-averse or risk-inclined. This can result in them making different choices under risk even if they value outcomes in exactly the same way. One pressing question that arises once we grant such permissiveness is what attitude to risk we should implement when choosing on behalf of other people. Are we permitted to implement any (...) of the rationally permissible risk attitudes, is there some specific risk attitude that is required when choosing for others, or are we required to defer to the risk attitudes of the people on whose behalf we are choosing? This article elaborates on this question, explains its wider practical and theoretical significance, provides an overview of existing answers, and explores how to go about providing a more systematic account of how to choose on behalf of others in risky contexts.

Intuitively, many people seem to hold that engaging in acts of virtual murder in videogames is morally permissible, whereas engaging in acts of virtual child molestation is morally impermissible. The Gamer’s Dilemma (Luck in Ethics Inf Technol 11:31–36, 2009) challenges these intuitions by arguing that it is unclear whether there is a morally relevant difference between these two types of virtual actions. There are two main responses in the literature to this dilemma. First, attempts to resolve the dilemma by defending (...) an account of the relevant moral differences between virtual murder and virtual child molestation. Second, attempts to dissolve the dilemma by undermining the intuitions that ground it. In this paper, we argue that a narrow version of the Gamer’s Dilemma seems to survive attempts to resolve or dissolve it away entirely, since neither approach seems to be able to solve the dilemma for all cases. We thus provide a contextually sensitive version of the dilemma that more accurately tracks onto the intuitions of gamers. However, we also argue that the intuitions that ground the narrow version of the Dilemma may not have a moral foundation, and we put forward alternative non-moral normative foundations that seem to better account for the remaining intuitive difference between the two types of virtual actions. We also respond to proposed solutions to the Gamer’s Dilemma in novel ways and set out areas for future empirical work in this area. (shrink)

This book offers a much-needed new political theory of an old phenomenon. The last decade alone has marked the highest number of migrations in recorded history. Constrained by environmental, economic, and political instability, scores of people are on the move. But other sorts of changes—from global tourism to undocumented labor—have led to the fact that to some extent, we are all becoming migrants. The migrant has become the political figure of our time. Rather than viewing migration as the exception to (...) the rule of political fixity and citizenship, Thomas Nail reinterprets the history of political power from the perspective of the movement that defines the migrant in the first place. Applying his "kinopolitics" to several major historical conditions and figures of migration, he provides fresh tools for the analysis of contemporary migration. (shrink)

This paper challenges the widely held view that ‘good for’, ‘well-being’, and related terms express a distinctive evaluative concept of central importance for ethics and separate from ‘simply good’ as used by G. E. Moore and others. More specifically, it argues that there's no philosophically useful good-for or well-being concept that's neither merely descriptive in the sense of naturalistic nor reducible to ‘simply good’. The paper distinguishes two interpretations of the common claim that the value ‘good for’ expresses is distinctively (...) ‘subject-relative’. One concerns the ground of this value, or the properties that make something good for you; it says these must involve some relation to you. The other concerns the resulting value itself, or what supervenes on this ground; it says that too involves a relation. Neither interpretation, the paper argues, yields a significantly distinct evaluative concept. The ethically fundamental evaluative concept is just ‘simply good’. (shrink)

Lay persons may have intuitions about morality's objectivity. What do these intuitions look like? And what are their causes and consequences? In recent years, an increasing number of scholars have begun to investigate these questions empirically. This article presents and assesses the resulting area of research as well as its potential philosophical implications. First, we introduce the methods of empirical research on folk moral objectivism. Second, we provide an overview of the findings that have so far been made. Third, we (...) raise a number of methodological worries that cast doubt upon these findings. And fourth, we discuss ways in which lay persons' intuitions aboutmoral objectivity may bear on philosophical claims. (shrink)

The Gamer’s Dilemma refers to the philosophical challenge of justifying the intuitive difference people seem to see between the moral permissibility of enacting virtual murder and the moral impermissibility of enacting virtual child molestation in video games (Luck Ethics and Information Technology, 1:31, 2009). Recently, Luck in Philosophia, 50:1287–1308, 2022 has argued that the Gamer’s Dilemma is actually an instance of a more general “paradox”, which he calls the “paradox of treating wrongdoing lightly”, and he proposes a graveness resolution to (...) this paradox. In response, we argue for four key claims. First, we accept Luck’s expansion of the Gamer’s Dilemma to be applicable to a wider set of media, but give a novel recasting of this in terms of the Paradox of Fictionally Going Too Far. Second, we develop a novel criticism of Luck in Philosophia, 50:1287–1308, 2022 graveness resolution to this broader paradox. Third, we argue that the Paradox of Fictionally Going Too Far helps to expose an implicit moralism in the Gamer’s Dilemma literature when compared to relevant nearby literatures about other forms of media. Fourth, we consider a range of non-moral, cultural and media conventions that plausibly help to dissolve the intuitive moral gap between non-sexual and sexual violence that is central to this paradox.

The claim that common sense regards free will and moral responsibility as compatible with determinism has played a central role in both analytic and experimental philosophy. In this paper, we show that evidence in favor of this “natural compatibilism” is undermined by the role that indeterministic metaphysical views play in how people construe deterministic scenarios. To demonstrate this, we re-examine two classic studies that have been used to support natural compatibilism. We find that although people give apparently compatibilist responses, this (...) is largely explained by the fact that people import an indeterministic metaphysics into deterministic scenarios when making judgments about freedom and responsibility. We conclude that judgments based on these scenarios are not reliable evidence for natural compatibilism. (shrink)

When does it make sense to act randomly? A persuasive argument from Bayesian decision theory legitimizes randomization essentially only in tie-breaking situations. Rational behaviour in humans, non-human animals, and artificial agents, however, often seems indeterminate, even random. Moreover, rationales for randomized acts have been offered in a number of disciplines, including game theory, experimental design, and machine learning. A common way of accommodating some of these observations is by appeal to a decision-maker’s bounded computational resources. Making this suggestion both precise (...) and compelling is surprisingly difficult. Toward this end, I propose two fundamental rationales for randomization, drawing upon diverse ideas and results from the wider theory of computation. The first unifies common intuitions in favour of randomization from the aforementioned disciplines. The second introduces a deep connection between randomization and memory: access to a randomizing device is provably helpful for an agent burdened with a finite memory. Aside from fit with ordinary intuitions about rational action, the two rationales also make sense of empirical observations in the biological world. Indeed, random behaviour emerges more or less where it should, according to the proposal. (shrink)

I defend the thesis that beliefs are constitutively normative from two kinds of objection. After clarifying what a “blindspot” proposition is and the different types of blindspots there can be, I show that the existence of such propositions does not undermine the thesis that beliefs are essentially governed by a negative truth norm. I argue that the “normative variance” exhibited by this norm is not a defect. I also argue that if we accept a distinction between subjective and objective norms (...) there need be no worrying tension between doxastic norms of truth and doxastic norms of evidence. I show how a similar approach applies to the attitude of guessing. I then suggest that if we distinguish between practical and theoretical rationality, we will prefer a negative form of norm that does not positively oblige us to form beliefs. I finish by considering an alternative possible subjunctive form of norm that would also avoid problems with blindspots but suggest this has a non-intuitive consequence. (shrink)

This paper provides an agonistic interpretation of Robert Brandom's social-pragmatic account of normativity. I argue that social practice, on this approach, should be seen not just as cooperative, but also as contestatory. This aspect, which has so far remained implicit, helps to illuminate Brandom's claim that normative statuses are ‘instituted’ by social practices: normative statuses are brought into play in mutual engagement, and are only in play from an engaged social perspective among others. Moreover, in contrast to a positivist or (...) conventionalist understanding of Brandom's work, it shows that the possibility of a critical stance toward existing practices is not only compatible with, but already implicit in this form of pragmatism. This can be made explicit with the notion of farcical practices: practices that are treated merely as if they institute genuine commitments and entitlements. Interpreting a practice as farcical is taking a critical stance toward it, and this possibility is inherent in Brandom's theoretical framework. This opens the way for a fruitful appropriation of Brandom's pragmatism for social and political philosophy. (shrink)

We argue that a semantics for counterfactual conditionals in terms of comparative overall similarity faces a formal limitation due to Arrow’s impossibility theorem from social choice theory. According to Lewis’s account, the truth-conditions for counterfactual conditionals are given in terms of the comparative overall similarity between possible worlds, which is in turn determined by various aspects of similarity between possible worlds. We argue that a function from aspects of similarity to overall similarity should satisfy certain plausible constraints while Arrow’s impossibility (...) theorem rules out that such a function satisfies all the constraints simultaneously. We argue that a way out of this impasse is to represent aspectual similarity in terms of ranking functions instead of representing it in a purely ordinal fashion. Further, we argue against the claim that the determination of overall similarity by aspects of similarity faces a difficulty in addition to the Arrovian limitation, namely the incommensurability of different aspects of similarity. The phenomena that have been cited as evidence for such incommensurability are best explained by ordinary vagueness. (shrink)

Moral and political forms of constructivism accord to people strong, “constitutive” forms of discursive standing and so build on, or express, a commitment to discursive respect. The paper explores dimensions of discursive respect, i.e., depth, scope, and purchase; it addresses tenuous interdependencies between them; on this basis, it identifies limitations of the idea of discursive respect and of constructivism. The task of locating discursive respect in the normative space defined by its three dimensions is partly, and importantly, an ethical task (...) that is beyond constructivism. Interdependencies between these dimensions call into question the possibility of a plausible and coherent form of discursive respect that is deep, inclusive in scope, and rich in purchase. This does not mean that we should reject discursive respect, or constructivism, for that matter. But it suggests that the task of reconciling the dimensions of discursive respect may not allow for widely shareable results. This task needs to be addressed on non-constructivist grounds. Accordingly, we have reasons to concede that constitutive forms of discursive standing are less fundamental in the order of justification than weaker, “derivative” forms, and this is so especially if we take constitutive standing to mark an important good.

We seek to elucidate the philosophical context in which one of the most important conceptual transformations of modern mathematics took place, namely the so-called revolution in rigor in infinitesimal calculus and mathematical analysis. Some of the protagonists of the said revolution were Cauchy, Cantor, Dedekind,and Weierstrass. The dominant current of philosophy in Germany at the time was neo-Kantianism. Among its various currents, the Marburg school (Cohen, Natorp, Cassirer, and others) was the one most interested in matters scientific and mathematical. Our (...) main thesis is that Marburg neo-Kantian philosophy formulated a sophisticated position towards the problems raised by the concepts of limits and infinitesimals. The Marburg school neither clung to the traditional approach of logically and metaphysically dubious infinitesimals, nor whiggishly subscribed to the new orthodoxy of the “great triumvirate” of Cantor, Dedekind, and Weierstrass that declared infinitesimals conceptus nongrati in mathematical discourse. Rather, following Cohen’s lead, the Marburg philosophers sought to clarify Leibniz’s principle of continuity, and to exploit it in making sense of infinitesimals and related concepts. (shrink)

In the recent debate between conceptualists and nonconceptualists about perceptual content, Kant’s notion of intuition has been invoked on both sides. Conceptualists claim Kant as a forerunner of their position, arguing that Kantian intuitions have the same kind of content as conceptual thought. On the other hand, nonconceptualists claim Kant as a forerunner of their own position, contending that Kantian intuitions have a distinctly nonconceptual kind of content. In this paper, I argue first, that both sides are wrong about Kant, (...) secondly, that neither side can properly account for the epistemic function of intuition, and thirdly, that Kant’s own notion of intuition contains the resources for a third alternative. The epistemic function of an intuition for Kant is to furnish the sensory representation of an object of cognition. Conceptualism cannot account for this function because it construes perception as a species of thought. As a proper appreciation of Kant’s reasons for insisting upon the heterogeneity of thought and perception puts one in a position to see, any view that does this will fail to do justice to the distinctly sensory nature of intuition. Nonconceptualism, on the other hand, cannot account for the epistemic function of intuition because it views intuition as self-standing, and thus as completely independent from thought. As a consequence, nonconceptualism is not entitled to claim that an intuition is itself a cognitive state. I show that Kant’s actual view avoids both these extremes because it involves a different way of conceiving how perception is informed by conceptual thought. Building on this conception, Kant is able to preserve the distinctly sensory nature of intuition, while also securing proper cognitive standing for it. As a result, Kant’s notion of intuition provides the resources for an alternative account of how thought relates to the senses – one that avoids the shortcomings of the positions staked out in the contemporary debate.

Issues of reliability are claiming center-stage in the epistemology of machine learning. This paper unifies different branches in the literature and points to promising research directions, whilst also providing an accessible introduction to key concepts in statistics and machine learning – as far as they are concerned with reliability.

This paper examines the evolution of Edmund Husserl’s theory of perceptual occlusion. This task is accomplished in two stages. First, I elucidate Husserl’s conclusion, from his 1901 Logical Investigations, that the occluded parts of perceptual objects are intended by partial signitive acts. I focus on two doctrines of that account. I examine Husserl’s insight that signitive intentions are composed of Gehalt and I discuss his conclusion that signitive intentions sit on the continuum of fullness. Second, the paper discloses how Husserl (...) transforms his 1901 philosophy in his 1913 revisions to the Sixth Logical Investigation, affirming that the occluded parts of perceptual objects are intended by empty contiguity acts. I demonstrate how he overturns the two core doctrines of his theory from the Investigations in these revisions, claiming that empty intentions are not composed of Gehalt and asserting that those acts break with the continuum of fullness. Husserl implements these changes to solve problems that arise from his recognition of two new kinds of intentions; darker and completely dark acts. Finally, in the conclusion, I cash out this analysis, by indicating that, in 1913, Husserl transforms his theory of fulfillment on the basis of his new insights about empty acts. (shrink)

In answering normative questions, researchers sometimes appeal to the concept of basic needs. Their guiding idea is that our first priority should be to ensure that everybody is able to meet these needs—to have enough in terms of food, water, shelter, and so on. This article provides an opinionated overview of basic needs in normative contexts. Any basic needs theory must answer three questions: (1) What are basic needs? (2) To what extent do basic needs generate reasons for action and (...) how are these reasons to be understood? (3) How are basic needs and their satisfaction to be measured? I address these questions in turn. Then I also briefly discuss the theoretical potential of appealing to basic needs in normative contexts. It turns out that future research in this area could benefit from a higher degree of interdisciplinarity and methodological reflection, and that, generally speaking, basic needs theories are more promising than they have often been claimed to be.
