In this paper I aim to undermine Stoic and Neo-Stoic readings of Benedict de Spinoza by examining the latter’s strong agreements with Epicurus (a notable opponent of the Stoics) on the nature and ethical role of pleasure in living a happy life. Ultimately, I show that Spinoza and Epicurus are committed to three central claims which the Stoics reject: (1) pleasure holds a necessary connection to healthy natural being, (2) pleasure manifests healthy being through positive changes in state and (...) states of healthy being per se, and (3) pleasure is by nature good. The Stoics reject these three claims due to their views on pleasant sensations as preferred moral indifferents and passionate pleasures as diseases of the soul, views which Spinoza (due to the abovementioned commitments) is strongly opposed to, thereby placing him (at least on the subject of pleasure) outside the realm of merely following or improving on Stoic doctrines. From this comparative analysis we also gain deeper insight into both Spinoza’s engagement with ancient Greek philosophy and the value of Epicureanism and Spinozism in helping us achieve and maintain happiness in the present day, particularly with respect to the benefits and harms of bodily and mental pleasures.

Ontologies are being used increasingly to promote the reusability of scientific information by allowing heterogeneous data to be integrated under a common, normalized representation. Definitions play a central role in the use of ontologies both by humans and by computers. Textual definitions allow ontologists and data curators to understand the intended meaning of ontology terms and to use these terms in a consistent fashion across contexts. Logical definitions allow machines to check the integrity of ontologies and reason over data annotated (...) with ontology terms to make inferences that promote knowledge discovery. Therefore, it is important not only to include in ontologies multiple types of definitions in both formal and in natural languages, but also to ensure that these definitions meet good quality standards so they are useful. While tools such as Protégé can assist in creating well-formed logical definitions, producing good definitions in a natural language is still to a large extent a matter of human ingenuity supported at best by just a small number of general principles. For lack of more precise guidelines, definition authors are often left to their own personal devices. This paper aims to fill this gap by providing the ontology community with a set of principles and conventions to assist in definition writing, editing, and validation, by drawing on existing definition writing principles and guidelines in lexicography, terminology, and logic.

We performed a qualitative analysis of the Thesaurus in order to assess its conformity with principles of good practice in terminology and ontology design. We used both the on-line browsable version of the Thesaurus and its OWL-representation (version 04.08b, released on August 2, 2004), measuring each in light of the requirements put forward in relevant ISO terminology standards and in light of ontological principles advanced in the recent literature. Version 04.08b of the NCI Thesaurus suffers from the same broad range (...) of problems that have been observed in other biomedical terminologies. For its further development, we recommend the use of a more principled approach that allows the Thesaurus to be tested not just for internal consistency but also for its degree of correspondence to that part of reality which it is designed to represent.

This paper initiates the reverse mathematics of social choice theory, studying Arrow's impossibility theorem and related results including Fishburn's possibility theorem and the Kirman–Sondermann theorem within the framework of reverse mathematics. We formalise fundamental notions of social choice theory in second-order arithmetic, yielding a definition of countable society which is tractable in RCA0. We then show that the Kirman–Sondermann analysis of social welfare functions can be carried out in RCA0. This approach yields a proof of Arrow's theorem in RCA0, and (...) thus in PRA, since Arrow's theorem can be formalised as a Π01 sentence. Finally we show that Fishburn's possibility theorem for countable societies is equivalent to ACA0 over RCA0. (shrink)

Short overview of the From Small Beginnings Project and its relevance for resisting eugenics in contemporary society.

Johannes Daubert he was an acknowledged leader, and in some respects the founder, of the early phenomenological movement, and was considered – as much by its members as by Husserl himself – the most brilliant member of the group. In Daubert’s unpublished writings we find a series of reflections on Lask, and on Neo-Kantianism, which form the subject-matter of this paper. They range over topics such as the ontology of the ‘Sachverhalt’ or state of affairs, truthvalues (Wahrheitswerte) and the value (...) of truth, negative judgments and the copula, and the relation between perception and judgment.

Ingarden distinguishes four strata making up the structure of the literary work of art: the stratum of word sounds and sound-complexes; the stratum of meaning units; the stratum of represented objectivities (characters, actions, settings, and so forth); and the stratum of schematized aspects (perspectives under which the represented objectivities are given to the reader). It is not only works of literature which manifest this four-fold structure but also certain borderline cases such as newspaper articles, scientific works, biographies, and so forth. (...) Ingarden specifies what is characteristic of a work of literature by asserting that all declarative sentences appearing in the stratum of meaning units of such work possess what he calls a quasi-judgmental character. We discuss here Ingarden’s theory of quasi-judgments and draw out its implication that all works of literature are works of fiction through and through. (shrink)

It is a striking fact from reverse mathematics that almost all theorems of countable and countably representable mathematics are equivalent to just five subsystems of second order arithmetic. The standard view is that the significance of these equivalences lies in the set existence principles that are necessary and sufficient to prove those theorems. In this article I analyse the role of set existence principles in reverse mathematics, and argue that they are best understood as closure conditions on the powerset of (...) the natural numbers.

The pivotal role of the relation part-of in the description of living organisms is widely acknowledged. Organisms are open systems, which means that in contradistinction to mechanical artifacts they are characterized by a continuous flow and exchange of matter. A closer analysis of the spatial relations in biological organisms reveals that the decision as to whether a given particular is part-of a second particular or whether it is only contained-in the second particular is often controversial. We here propose a rule-based (...) approach which allows us to decide on the basis of well-defined criteria which of the two relations holds between two anatomical objects, given that one spatially includes the other. We discuss the advantages and limitations of this approach, using concrete examples from human anatomy. (shrink)

Changes in an upper level ontology have obvious conse-quences for the domain ontologies that use it at lower levels. It is therefore crucial to document the changes made between successive versions of ontologies of this kind. We describe and apply a method for tracking, explaining and measuring changes between successive versions of upper level ontologies such as the Basic Formal Ontology (BFO). The proposed change-tracking method extends earlier work on Realism-Based Ontology Versioning (RBOV) and Evolutionary Terminology Auditing (ETA). We describe (...) here the application of this evaluation method to changes between BFO 1.0, BFO 1.1, and BFO 2.0. We discuss the issues raised by this application and describe the extensions which we added to the original evaluation schema in order to account for changes in an ontology of this type. Our results show that BFO has undergone eight types of changes that can be systematically explained by the extended evaluation schema. Finally, we discuss problematic cases, possible pitfalls and certain limits of our study that we propose to address in future work. (shrink)

The shape of the Earth's surface, its topography, is a fundamental dimension of the environment, shaping or mediating many other environmental flows or functions. But there is a major divergence in the way that topography is conceptualized in different domains. Topographic cartographers, information scientists, geomorphologists and environmental modelers typically conceptualize topographic variability as a continuous field of elevations or as some discrete approximation to such a field. Pilots, explorers, anthropologists, ecologists, hikers, and archeologists, on the other hand, typically conceptualize this (...) same variability in terms of hills and valleys, mountains and plains, barrows and trenches, that is, as (special sorts of) objects, with locations, shapes, and often names of their own. In this chapter, we sketch an approach to bridging this fundamental gap in geographic information infrastructure. (shrink)

Neo-Kantianism is common conceived as a philosophy ‘from above’, excelling in speculative constructions – as opposed to the attitude of patient description which is exemplified by the phenomenological turn ‘to the things themselves’. When we study the work of Emil Lask in its relation to that of Husserl and the phenomenologists, however, and when we examine the influences moving in both directions, then we discover that this idea of a radical opposition is misconceived. Lask himself was influenced especially by Husserl’s (...) Logical Investigations, and Husserl, especially in his later writings, was in some respects closer to Kant than were the Neo-Kantians. The contrast between the two philosophers can be illustrated by looking at their view of the objects of judgment; for Lask, as for Kant, judgment can relate to the thing as such only in an indirect way. The world of judgment is a collection of ‘imitations holding a secondary position’. It is cut apart from the plain world of real things by what Lask calls a ‘chasm of artificiality and imagery’. For Husserl, in contrast, the object of judgment is a ‘Sachverhalt’ or state of affairs, something ontologically ‘positive’ in the sense that it is an entity in its own right and does not point beyond itself in the manner of a mere sign or proxy for something else.

Alfred Tarski was one of the greatest logicians of the twentieth century. His influence comes not merely through his own work but from the legion of students who pursued his projects, both in Poland and Berkeley. This chapter focuses on three key areas of Tarski's research, beginning with his groundbreaking studies of the concept of truth. Tarski's work led to the creation of the area of mathematical logic known as model theory and prefigured semantic approaches in the philosophy of language (...) and philosophical logic, such as Kripke's possible worlds semantics for modal logic. We also examine the paradoxical decomposition of the sphere known as the Banach–Tarski paradox. Finally we examine Tarski's work on decidable and undecidable theories, which he carried out in collaboration with students such as Mostowski, Presburger, Robinson and others. (shrink)

This review focuses on the Ogdoas scholastica by Jacob Lorhard, published in 1606. The importance of this document turns on the fact that it contains what is almost certainly the first published occurrence of the term “ontology.” The body of the work consists in a series of diagrams called “diagraphs.” Relevant features of this compendium of diagraphs are: 1. that it does not in fact contain the word “ontology,” and 2. that Lorhard himself was not responsible for its content.

Reverse mathematics studies which subsystems of second order arithmetic are equivalent to key theorems of ordinary, non-set-theoretic mathematics. The main philosophical application of reverse mathematics proposed thus far is foundational analysis, which explores the limits of different foundations for mathematics in a formally precise manner. This paper gives a detailed account of the motivations and methodology of foundational analysis, which have heretofore been largely left implicit in the practice. It then shows how this account can be fruitfully applied in the (...) evaluation of major foundational approaches by a careful examination of two case studies: a partial realization of Hilbert’s program due to Simpson [1988], and predicativism in the extended form due to Feferman and Schütte. -/- Shore [2010, 2013] proposes that equivalences in reverse mathematics be proved in the same way as inequivalences, namely by considering only omega-models of the systems in question. Shore refers to this approach as computational reverse mathematics. This paper shows that despite some attractive features, computational reverse mathematics is inappropriate for foundational analysis, for two major reasons. Firstly, the computable entailment relation employed in computational reverse mathematics does not preserve justification for the foundational programs above. Secondly, computable entailment is a Pi-1-1 complete relation, and hence employing it commits one to theoretical resources which outstrip those available within any foundational approach that is proof-theoretically weaker than Pi-1-1-CA0.

Many of the items that humans consume are produced in ways that involve serious harms to persons. Familiar examples include the harms involved in the extraction and trade of conflict minerals (e.g. coltan, diamonds), the acquisition and import of non- fair trade produce (e.g. coffee, chocolate, bananas, rice), and the manufacture of goods in sweatshops (e.g. clothing, sporting equipment). In addition, consumption of certain goods (significantly fossil fuels and the products of the agricultural industry) involves harm to the environment, to (...) future persons, and to current persons in low-lying and developing countries, by way of their impacts on climate change. When it comes to such large-scale harms, it's easy for the individual to feel helpless. Even if she sincerely wishes things were otherwise, she may wonder what she could possibly do to make them so. In this paper I briefly explore several promising avenues for generating duties in individuals to consume ethically, and develop one in particular: that an individual ought to signal her commitments to others, as a first step in collectivizing to act against unjust global labour practices.

The concept of niche (setting, context, habitat, environment) has been little studied by ontologists, in spite of its wide application in a variety of disciplines from evolutionary biology to economics. What follows is a first formal theory of this concept, a theory of the relations between objects and their niches. The theory builds upon existing work on mereology, topology, and the theory of spatial location as tools of formal ontology. It will be illustrated above all by means of simple biological (...) examples, but the concept of niche should be understood as being, like concepts such as part, boundary, and location, a structural concept that is applicable in principle to a wide range of different domains.

This essay is a response to Luis M. Augusto’s intriguing paper on the rift between mainstream and formal ontology. I will show that there are in fact two questions at issue here: 1. concerning the links between mainstream and formal approaches within philosophy, and 2. concerning the application of philosophy (and especially philosophical ontology) in support of information-driven research for example in the life sciences.

The truthmaker theory rests on the thesis that the link between a true judgment and that in the world to which it corresponds is not a one-to-one but rather a one-to-many relation. An analogous thesis in relation to the link between a singular term and that in the world to which it refers is already widely accepted. This is the thesis to the effect that singular reference is marked by vagueness of a sort that is best understood in supervaluationist terms. (...) In what follows we show that the supervaluationist approach to singular reference, when wedded to the truthmaker idea, yields a framework of surprising power, which offers a uniform set of solutions to a range of problems regarding identity, reference and knowledge, problems which have hitherto been dealt with on an ad hoc basis.

The fact that there is such a thing as a degree of formedness [Gestaltung], that every Gestalt has a certain Gestalt level, is of fundamental significance. A rose is a Gestalt of higher level than a heap of sand: this we recognize just as immediately as that red is a fuller, more lively colour than grey. The higher Gestalten are distinguished further from the lower by the fact that the product of unity and multiplicity [Einheit und Mannigfaltigkeit] is in their (...) case greater. (shrink)

How do we justify the normative standards to which we appeal in support of our moral progress judgments, given their historical and cultural contingency? To answer this question in a noncircular way, Elizabeth Anderson and Philip Kitcher appeal exclusively to formal features of the methodology by which a moral change was brought about; some moral methodologies are systematically less prone to bias than others and are therefore less vulnerable to error. However, we argue that the methodologies espoused by Anderson and (...) Kitcher implicitly appeal to the substantive principle of “moral universalism.” This sets up the positive project of the paper: an attempt to vindicate moral universalism with a pragmatic genealogy. Using resources from cultural evolutionary theory and the history of ideas we argue that the universalistic norms widely committed to in many societies today have the function of maintaining cooperation in large anonymous groups. Furthermore, while universalistic norms play this instrumental role, their functional benefits are best secured when people following such norms do so for intrinsic rather than instrumental reasons. Finally, having elaborated our pragmatic genealogy, we close by considering how this genealogy should affect our commitment to moral universalism and how it can complement the methods of Anderson and Kitcher.

The Foundational Model of Anatomy (FMA) symbolically represents the structural organization of the human body from the macromolecular to the macroscopic levels, with the goal of providing a robust and consistent scheme for classifying anatomical entities that is designed to serve as a reference ontology in biomedical informatics. Here we articulate the need for formally clarifying the is-a and part-of relations in the FMA and similar ontology and terminology systems. We diagnose certain characteristic errors in the treatment of these relations (...) and show how these errors can be avoided through adoption of the formalism we describe. We then illustrate how a consistently applied formal treatment of taxonomy and partonomy can support the alignment of ontologies. (shrink)

Does ?ought? imply ?can? for collectives' obligations? In this paper I want to establish two things. The first, what a collective obligation means for members of the collective. The second, how collective ability can be ascertained. I argue that there are four general kinds of obligation, which devolve from collectives to members in different ways, and I give an account of the distribution of obligation from collectives to members for each of these kinds. One implication of understanding collective obligation and (...) ability in the proposed way is that a group can be blameworthy for failing to realize its obligation even when no member of the group is blameworthy for failing to realize her obligation.

This paper, while neutral on questions about the minimality of truth, argues for the non-minimality of truth-aptness.

This paper addresses the question of what organisms are and therefore what kinds of biological entities qualify as organisms. For some time now, the concept of organismality has been eclipsed by the notion of individuality. Biological individuals are those systems that are units of selection. I develop a conception of organismality that does not rely on evolutionary considerations, but instead draws on development and ecology. On this account, organismality and individuality can come apart. Organisms, in my view, are as Godfrey- (...) class='Hi'>Smith puts it “essentially persisters.” I argue that persistence is underpinned by differentiation, integration, development, and the constitutive embeddedness of organisms in their worlds. I examine two marginal cases, the Portuguese Man O’ War and the honey bee colony, and show that both count as organisms in light of my analysis. Next, I examine the case of holobionts, hosts plus their microsymbionts, and argue that they can be counted as organisms even though they may not be biological individuals. Finally, I consider the question of whether other, less tightly integrated biological systems might also be treated as organisms. (shrink)

Climate change appears to be a classic aggregation problem, in which billions of individuals perform actions none of which seem to be morally wrong taken in isolation, and yet which combine to drive the global concentration of greenhouse gases (GHGs) ever higher toward environmental (and humanitarian) catastrophe. When an individual can choose between actions that will emit differing amounts of GHGs―such as to choose a vegan rather than carnivorous meal, to ride a bike to work rather than drive a car, (...) or to take a reusable bag to the supermarket rather than send another plastic bag to landfill―does she have any reason to choose the lower-emitting actions? In this chapter I'll reject the claim that individuals don't make a difference when it comes to climate change. I first discuss making a difference with every action, as a way of getting clearer about how individuals' actions impact causally on the harms resulting from climate change, making a distinction so far overlooked in the climate ethics discussion between 'macro' thresholds like ice-cap melt, and 'micro' thresholds like severe weather events. I set aside making a difference with every action as implausible, and then move on to discuss both low probability of major difference, and high probability of minor difference. I argue that both of these are plausible characterizations of individuals' causal contributions to climate change. I conclude by noting some policy implications of having (probabilistic) individual difference-making back in play. (shrink)

When Adam Smith published his celebrated writings on economics and moral philosophy he famously referred to the operation of an invisible hand. Adam Smith's Political Philosophy makes visible the invisible hand by examining its significance in Smith's political philosophy and relating it to similar concepts used by other philosophers, revealing a distinctive approach to social theory that stresses the significance of the unintended consequences of human action. This book introduces greater conceptual clarity to the discussion of the (...) invisible hand and the related concept of unintended order in the work of Smith and in political theory more generally. By examining the application of spontaneous order ideas in the work of Smith, Hume, Hayek and Popper, Adam Smith's Political Philosophy traces similarities in approach and from these builds a conceptual, composite model of an invisible hand argument. While setting out a clear model of the idea of spontaneous order the book also builds the case for using the idea of spontaneous order as an explanatory social theory, with chapters on its application in the fields of science, moral philosophy, law and government.

One reason for the renewed interest in Austrian philosophy, and especially in the work of Brentano and his followers, turns on the fact that analytic philosophers have become once again interested in the traditional problems of metaphysics. It was Brentano, Husserl, and the philosophers and psychologists whom they influenced, who drew attention to the thorny problem of intentionality, the problem of giving an account of the relation between acts and objects or, more generally, between the psychological environments of cognitive subjects (...) and the different sorts of external (physical, geographical, social) environments which they inhabit. The present essay addresses this environmental version of the problem of intentionality. It draws not only on the work of Husserl and Scheler but also on the Gestalt psychological writings of Kurt Koffka and Kurt Lewin. It considers the influential subjective idealist theory of animal environments put forward by J. von Uexküll and contrasts this with a realist theory of organism-environment interaction based on the work of the ecological psychologists J. J. Gibson and Roger Barker. This realist theory is then exploited as a basis for an ontology of social objects of a range of different sorts. (shrink)

Scholars have argued that Plato's decision to include women in the ruling class was either intended as a joke, or else was forced on him by other political commitments. In tis paper, I argue that the arguments he offers for including women in positions of power can and should be taken as sincere.

The essay constructs an ontological theory designed to capture the categories instantiated in those portions or levels of reality which are captured in our common sense conceptual scheme. It takes as its starting point an Aristotelian ontology of “substances” and “accidents”, which are treated via the instruments of mereology and topology. The theory recognizes not only individual parts of substances and accidents, including the internal and external boundaries of these, but also universal parts, such as the “humanity” which is an (...) essential part of both Tom and Dick, and also “individual relations”, such as Tom’s promise to Dick, or their current handshake.

If Mont Blanc is a vague object, then its vagueness will depend on the context in which reference is made. In a geological context the mountain might include only rock, perhaps together with a certain amount of air in the crevices and tunnels which have been formed beneath its surface. In a context of soil chemistry we might include also a surrounding thin layer of organic matter. In a skiing context we might include some snow. This essay sketches in informal (...) terms the theory of granular partitions, which is designed to do justice to this context-dependence of vagueness by means of what might be described as a contextualized supervaluationism. Granularity and vagueness, it is argued, are two sides of a single coin: what is vague at one level of granularity may appear crisp at another. The resultant theory can be shown to resolve certain problems in our description of perceptual content, for example when John says that he sees the wall, but that he does not see the molecules by which the wall is constituted.

The politics of climate change is marked by the fact that countries are dragging their heels in doing what they ought to do; namely, creating a binding global treaty, and fulfilling the duties assigned to each of them under it. Many different agents are culpable in this failure. But we can imagine a stylised version of the climate change case, in which no agents are culpable: if the bad effects of climate change were triggered only by crossing a particular threshold, (...) and it was reasonably, but mistakenly, believed by each country that insufficiently many other countries were willing to cooperate in order for that threshold to remain uncrossed, no country would be required to make a unilateral contribution. Yet even without culpability, we can diagnose a moral ill: the world has gone other than it should have. If not for the mistaken beliefs, there would have been a global climate treaty, and all the avoidance of future suffering that would come with it. In this article I argue that this moral ill has implications for the non-culpable agents, in that it generates duties to disgorge actual holdings over and above the counterpart holdings in the relevant counterfactual: those holdings the agents would have had, were the world to have gone as it should.

In her ‘On the apparent paradox of ideal theory’, Laura Valentini combines three supposedly plausible premises to derive the paradoxical result that ideal theory is both unable to, and indispensable for, guiding action. Her strategy is to undermine one of the three premises by arguing that there are good and bad kinds of ideal theory, and only the bad kinds are vulnerable to the strongest version of their opponents’ attack. By undermining one of the three premises she releases ideal theorists (...) from the paradox, which is as follows. (1) Any sound theory of justice is action-guiding. (2) Any sound theory of justice is ideal. (3) Any ideal theory fails to be action-guiding. Here I shall respond to Valentini in two ways. First, I shall show that both (1) and (2) are false. The falsity of either is sufficient to release ideal theorists from the paradox. Second, I shall show that Valentini’s response to (3) can be extended, because her bad kinds of ideal theory do not necessarily fail to guide action. The cumulative effect of my arguments further strengthens Valentini’s support of ideal theory. I will deal with premises (1) and (2) in Sections I and II, and (3) in Section III. (shrink)

In the era of “big data,” science is increasingly information driven, and the potential for computers to store, manage, and integrate massive amounts of data has given rise to such new disciplinary fields as biomedical informatics. Applied ontology offers a strategy for the organization of scientific information in computer-tractable form, drawing on concepts not only from computer and information science but also from linguistics, logic, and philosophy. This book provides an introduction to the field of applied ontology that is of (...) particular relevance to biomedicine, covering theoretical components of ontologies, best practices for ontology design, and examples of biomedical ontologies in use. After defining an ontology as a representation of the types of entities in a given domain, the book distinguishes between different kinds of ontologies and taxonomies, and shows how applied ontology draws on more traditional ideas from metaphysics. It presents the core features of the Basic Formal Ontology (BFO), now used by over one hundred ontology projects around the world, and offers examples of domain ontologies that utilize BFO. The book also describes Web Ontology Language (OWL), a common framework for Semantic Web technologies. Throughout, the book provides concrete recommendations for the design and construction of domain ontologies. (shrink)

Many jurisdictions prohibit or severely restrict the use of evidence about a defendant’s character to prove legal culpability. Situationists, who argue that conduct is largely determined by situational features rather than by character, can easily defend this prohibition. According to situationism, character evidence is misleading or paltry. -/- Proscriptions on character evidence seem harder to justify, however, on virtue ethical accounts. It appears that excluding character evidence either denies the centrality of character for explaining conduct—the situationist position—or omits probative evidence. (...) Situationism is, after all, presented as antithetical to virtue ethics. -/- This essay provides a virtue ethical defense of character evidence exclusion rules. We show that existing virtue ethical rebuttals to situationism themselves support prohibitions on character evidence; even if behavior arises from stable character traits, character evidence should be prohibited. In building our case, we provide a taxonomy of kinds of character judgment and reconcile the ubiquity and reasonableness of character judgments in ordinary life with the epistemic legitimacy of character evidence prohibitions in law.

For much of the first fifty years of its existence, analytic philosophy shunned discussions of normativity and ethics. Ethical statements were considered as pseudo-propositions, or as expressions of pro- or con-attitudes of minor theoretical significance. Nowadays, in contrast, prominent analytic philosophers pay close attention to normative problems. Here we focus our attention on the work of Searle, at the same time drawing out an important connection between Searle’s work and that of two other seminal figures in this development: H.L.A. Hart (...) and John Rawls. We show that all three thinkers tend to assume that there is but one type of normativity within the realm of social institutions – roughly, the sort of normativity that is involved in following the results of chess – and that they thereby neglect features that are of crucial significance for an adequate understanding of social reality.

I distinguish paradoxes and hypodoxes among the conundrums of time travel. I introduce ‘hypodoxes’ as a term for seemingly consistent conundrums that seem to be related to various paradoxes, as the Truth-teller is related to the Liar.

I also discuss Lewis’ treatment of time travel paradoxes, which I characterise as a Laissez Faire theory of time travel. Time travel paradoxes are impossible according (...) to Laissez Faire theories, while it seems hypodoxes are possible. (shrink)

Cognitive categories in the geographic realm appear to manifest certain special features as contrasted with categories for objects at surveyable scales. We have argued that these features reflect specific ontological characteristics of geographic objects. This paper presents hypotheses as to the nature of the features mentioned, reviews previous empirical work on geographic categories, and presents the results of pilot experiments that used English-speaking subjects to test our hypotheses. Our experiments show geographic categories to be similar to their non-geographic counterparts in (...) the ways in which they generate instances of different relative frequencies at different levels. Other tests, however, provide preliminary evidence for the existence of important differences in subjects’ categorizations of geographic and non-geographic objects, and suggest further experimental work especially with regard to the role in cognitive categorization of different types of object-boundaries at different scales.

What should we do when we won't do as we ought? Suppose it ought to be that the procrastinating professor accept the task of reviewing a book, and actually review the book. It seems clear that given he won't review it, he ought not to accept the task. That is a genuine moral obligation in light of less than perfect circumstances. I want to entertain the possibility that a set of such obligations form something like a 'practical morality'; that which (...) we ought to do given that we're unlikely or unwilling to do much of what ideal morality demands. If it is possible to give a coherent account of these kinds of obligations, then it is possible to entertain the idea that these obligations are in fact what morality demands. The conceptual truths about justice (good, right, fairness) that come from ideals are one thing; the actions that morality demands of people given their actual circumstances are quite another. In this paper I will ask about the kinds of facts that can be used to establish a more circumscribed set of obligations than we get from the orthodox view about moral obligation. (shrink)

‘Intersectionality’ is one of the rare pieces of academic jargon to make it out of the university and into the mainstream. The message is clear and well-known: your feminism had better be intersectional. But what exactly does this mean? This paper is partly an exercise in conceptual clarification, distinguishing at least six distinct types of claim found across the literature on intersectionality, and digging further into the most philosophically complex of these claims—namely the metaphysical and explanatory. It’s also partly a (...) reply to Sara Bernstein, who argued recently that the best interpretation of the metaphysical claim is explanatory priority. We’ll argue that duly clarified, it’s far from obvious that feminism had better be intersectional. At the very least, it had better not be only intersectional. (shrink)

Rindermann et al.’s article concludes that certain refugees may have a lower IQ and as a result may not provide as significant an economic contribution to host states compared to the average citizen, and so may be an economic cost. This commentary first casts doubt on this conclusion. It then, and most importantly, demonstrates that even if this conclusion were true, it would be irrelevant insofar as it would have no moral or legal significance in mitigating or defeating obligations towards (...) refugees. The commentary shows that any normative view that IQ and economic contributions can mitigate or defeat obligations to provide protection has unacceptable implications. The commentary then demonstrates that legal and moral obligations to refugees are in no part contingent on IQ and economic contributions and to suppose otherwise would simply represent a fundamental misunderstanding of the nature, grounds, and weight of obligations towards refugees. Hence, supposed IQ or economic contributions are entirely irrelevant to, and cannot undermine the strength of, refugees’ claims to protection nor states’ obligations to provide it. (shrink)

From a radical feminist perspective, gender is a cage. Or to be more precise, it’s two cages. If genders are cages, then surely we want to let people out. Being less constrained in our choices is something we all have reason to want: theorists in recent years have emphasized the importance of the capability to do and be many different things. At the very least, we should want an end to sex-based oppression. But what does this entail, when it comes (...) to gender? In this paper, I’ll compare four ‘transitional pathways’, with a view to considering how each relates to the ultimate end of ending sex-based oppression. Should we open the doors to the cages, so that people can move freely between them, but leave the cages themselves in place?. Should we add more cages?. Should we make the cages bigger, so that people have a lot more room to move around inside them? Or should we dismantle the cages, so there are no more genders at all?. Some of these options are ‘gender revisionist’, others are gender abolitionist. I’ll argue in favour of a gender abolitionist pathway. (shrink)

It is often assumed that trolling is an intentional action. The aim of the paper is to argue for a form of unintentional trolling. Firstly, we outline minimal conditions for intentional actions. Secondly, an unintentional trolling example is introduced. Thirdly, we will show that in some cases, an utterance can be expressive, while it is perceived as descriptive. On the basis of the justification-suppression model, we argue that the introduced trolling example is such a case. In order to bypass social (...) sanctions for expressing prejudices, agents unintentionally express their prejudices through stories that appear to be descriptive. Thereby, the characterized behavior does not fulfill the minimal conditions for intentional action. Fourthly, we give criteria that can be used to identify unintentional trolls. Finally, after unintentional trolling is analyzed, the trolls’ behavioral goals are considered. In conclusion, an analysis of unintentional trolling is given, which has explanatory benefits in contrast to the classic intentional trolling concepts. (shrink)

Recently two distinct forms of rule-utilitarianism have been introduced that differ on how to measure the consequences of rules. Brad Hooker advocates fixed-rate rule-utilitarianism, while Michael Ridge advocates variable-rate rule-utilitarianism. I argue that both of these are inferior to a new proposal, optimum-rate rule-utilitarianism. According to optimum-rate rule-utilitarianism, an ideal code is the code whose optimum acceptance level is no lower than that of any alternative code. I then argue that all three forms of rule-utilitarianism fall prey to two fatal (...) problems that leave us without any viable form of rule-utilitarianism. (shrink)

Why does ‘ethnic cleansing’ occur? Why does the rise of nationalist feeling in Europe and of Black separatist movements in the United States often go hand in hand with an upsurge of anti-Semitism? Why do some mixings of distinct religious and ethnic groups succeed, where others (for example in Northern Ireland, or in Bosnia) fail so catastrophically? Why do phrases like ‘balkanisation’, ‘dismemberment’, ‘mutilation’, ‘violation of the motherland’ occur so often in warmongering rhetoric? All of these questions are, it will (...) turn out, connected. To understand how they are connected we we will need to examine how human beings acquire a relationship to specific chunks of land, a relationship that is emotionally so strong that they are prepared to die – or kill – to protect that land for themselves or to win it back from others. Territoriality, the biologically rooted predisposition to defend core areas of home ranges against intruders, is a near-universal phenomenon amongst animals of all species. But the ways in which defended territories are conceived and demarcated differ widely from species to species and from group to group. By coming to an understanding of the geometry of these differences we can come to understand also some of the factors which give rise to interethnic conflict. (shrink)

Which of the two dominant arguments for duties to alleviate global poverty, supposing their premises were generally accepted, would be more likely to produce their desired outcome? I take Pogge's argument for obligations grounded in principles of justice, a "contribution" argument, and Campbell's argument for obligations grounded in principles of humanity, an "assistance" argument, to be prototypical. Were people to accept the premises of Campbell's argument, how likely would they be to support governmental reform in policies for international aid, or (...) to make individual contributions to international aid organizations? And I ask the same question, mutatis mutandis, for Pogge's argument. (shrink)
