For two ideally rational agents, does learning a finite amount of shared evidence necessitate agreement? No. But does it at least guard against belief polarization, the case in which their opinions get further apart? No. OK, but are rational agents guaranteed to avoid polarization if they have access to an infinite, increasing stream of shared evidence? No.

This essay has two aims. The first is to correct an increasingly popular way of misunderstanding Belot's Orgulity Argument. The Orgulity Argument charges Bayesianism with defect as a normative epistemology. For concreteness, our argument focuses on Cisewski et al.'s recent rejoinder to Belot. The conditions that underwrite their version of the argument are too strong and Belot does not endorse them on our reading. A more compelling version of the Orgulity Argument than Cisewski et al. present is available, however---a point (...) that we make by drawing an analogy with de Finetti's argument against mandating countable additivity. Having presented the best version of the Orgulity Argument, our second aim is to develop a reply to it. We extend Elga's idea of appealing to finitely additive probability to show that the challenge posed by the Orgulity Argument can be met. (shrink)

We provide counterexamples to some purported characterizations of dilation due to Pedersen and Wheeler :1305–1342, 2014, ISIPTA ’15: Proceedings of the 9th international symposium on imprecise probability: theories and applications, 2015).

Our aim here is to present a result that connects some approaches to justifying countable additivity. This result allows us to better understand the force of a recent argument for countable additivity due to Easwaran. We have two main points. First, Easwaran’s argument in favour of countable additivity should have little persuasive force on those permissive probabilists who have already made their peace with violations of conglomerability. As our result shows, Easwaran’s main premiss – the comparative principle – is strictly (...) stronger than conglomerability. Second, with the connections between the comparative principle and other probabilistic concepts clearly in view, we point out that opponents of countable additivity can still make a case that countable additivity is an arbitrary stopping point between finite and full additivity.

Recent impossibility theorems for fair risk assessment extend to the domain of epistemic justice. We translate the relevant model, demonstrating that the problems of fair risk assessment and just credibility assessment are structurally the same. We motivate the fairness criteria involved in the theorems as also being appropriate in the setting of testimonial justice. Any account of testimonial justice that implies the fairness/justice criteria must be abandoned, on pain of triviality.

Merging of opinions results underwrite Bayesian rejoinders to complaints about the subjective nature of personal probability. Such results establish that sufficiently similar priors achieve consensus in the long run when fed the same increasing stream of evidence. Initial subjectivity, the line goes, is of mere transient significance, giving way to intersubjective agreement eventually. Here, we establish a merging result for sets of probability measures that are updated by Jeffrey conditioning. This generalizes a number of different merging results in the literature. (...) We also show that such sets converge to a shared, maximally informed opinion. Convergence to a maximally informed opinion is a (weak) Jeffrey conditioning analogue of Bayesian “convergence to the truth” for conditional probabilities. Finally, we demonstrate the philosophical significance of our study by detailing applications to the topics of dynamic coherence, imprecise probabilities, and probabilistic opinion pooling. (shrink)

Bayesians often appeal to “merging of opinions” to rebut charges of excessive subjectivity. But what happens in the short run is often of greater interest than what happens in the limit. Seidenfeld and coauthors use this observation as motivation for investigating the counterintuitive short run phenomenon of dilation, since, they allege, dilation is “the opposite” of asymptotic merging of opinions. The measure of uncertainty relevant for dilation, however, is not the one relevant for merging of opinions. We explicitly investigate the (...) short run behavior of the metric relevant for merging, and show that dilation is independent of the opposite of merging. (shrink)

This article reviews an epochal change in international thinking about physical punishment of children from being a reasonable method of chastisement to one that is harmful to children and troubling to families. In addition, the article suggests shifts in thinking about physical punishment were originally pioneered as part and parcel of the dismantling of national laws granting fathers’ specific rights to admonish children under conventions of patria potestas. A comparative historical framework of analysis involving two case studies of Ireland and (...) Ghana illustrates non-unilinear pathways of international convergence towards the prohibition of physical punishment. The comparative historical analysis highlights the 1930s and 1940s as an era when Ireland began to reject patria potestas and religious or judicial rulings which allowed for children to be given ‘a good beating’ in family and school settings. However, from the same period, Ghana is seen to experience Christian remonstrations not to ‘spare the rod’ leading to the ‘conventional’ tradition of ‘this is how we do it here’. Two case studies serve to illustrate that banning physical punishment was less controversial in Ireland where allied traditions of patria potestas and disciplinarian Christian beliefs had lost their moral hegemony than in Ghana where such beliefs still held influence. The article concludes overall that normative campaigns against physical punishment of children emanate from a coherent paradigm of family policy where childcare, education, and well-being of children are embedded as everyday societal responsibilities rather than privatised or patriarchal familial obligations. The coherent model offers an alternative moral hegemony to neo-liberal and Janus-faced conceptualisations of good or ‘intact’ families versus ‘broken’ or ‘troubled’ families. (shrink)

There is a theorem that shows that it is impossible for an algorithm to jointly satisfy the statistical fairness criteria of Calibration and Equalised Odds non-trivially. But what about the recently advocated alternative to Calibration, Base Rate Tracking? Here, we show that Base Rate Tracking is strictly weaker than Calibration, and then take up the question of whether it is possible to jointly satisfy Base Rate Tracking and Equalised Odds in non-trivial scenarios. We show that it is not, thereby establishing (...) an even more general impossibility theorem. (shrink)

I provide a characterization of weakly pseudo-rationalizable choice functions---that is, choice functions rationalizable by a set of acyclic relations---in terms of hyper-relations satisfying certain properties. For those hyper-relations Nehring calls extended preference relations, the central characterizing condition is weaker than (hyper-relation) transitivity but stronger than (hyper-relation) acyclicity. Furthermore, the relevant type of hyper-relation can be represented as the intersection of a certain class of its extensions. These results generalize known, analogous results for path independent choice functions.

According to the received account of guilt in the philosophical literature, one cannot feel guilt unless one takes oneself to have done something morally wrong. But ordinary people feel guilt in many cases in which they do not take themselves to have done anything morally wrong. In this paper, I focus on one kind of guilt without perceived wrongdoing, guilt about being merely causally responsible for a bad state-of-affairs. I go on to present a novel account of guilt that explains (...) guilt about mere causal responsibility, according to which guilt represents part of the self as bound up with what is bad. (shrink)

What is the relation between small-scale collaborative plans and the execution of those plans within interactive contexts? I argue here that joint attention has a key role in explaining how shared plans and shared intentions are executed in interactive contexts. Within singular action, attention plays the functional role of enabling intentional action to be guided by a prior intention. Within interactive joint action, it is joint attention, I argue, that plays a similar functional role of enabling the agents to act (...) in a collaborative way such that their actions are rationally guided by a prior shared intention. This understanding of joint attention – as having a key functional role of enabling the rational guidance of joint intentional action by a prior shared intention – allows for an alternative understanding of the kind of minimal cooperation that infants can engage in. On this understanding, infants’ capacity to engage in joint actions is already an incipient capacity to engage in rational and intentional joint actions, albeit a capacity that is necessarily scaffolded by an adult rational co-partner.

It is a commonplace in economics that we should disregard sunk costs. The sunk cost effect might be widespread, goes the conventional wisdom, but we would be better off if we could rid ourselves of it. In this paper, I argue against the orthodoxy by showing that the sunk cost effect is often beneficial. Drawing on discussions of related topics in dynamic choice theory, I show that, in a range of cases, being disposed to honor sunk costs allows an agent (...) to mimic a resolute chooser, someone who adopts the best plan at the outset of a decision problem and sticks with it, even when resoluteness is unfeasible. I discuss several kinds of cases in which honoring sunk costs coincides with resolute choice. (shrink)

In many assessment problems—aptitude testing, hiring decisions, appraisals of the risk of recidivism, evaluation of the credibility of testimonial sources, and so on—the fair treatment of different groups of individuals is an important goal. But individuals can be legitimately grouped in many different ways. Using a framework and fairness constraints explored in research on algorithmic fairness, I show that eliminating certain forms of bias across groups for one way of classifying individuals can make it impossible to eliminate such bias across (...) groups for another way of dividing people up. And this point generalizes if we require merely that assessments be approximately bias-free. Moreover, even if the fairness constraints are satisfied for some given partitions of the population, the constraints can fail for the coarsest common refinement, that is, the partition generated by taking intersections of the elements of these coarser partitions. This shows that these prominent fairness constraints admit the possibility of forms of intersectional bias. (shrink)

What is the relation between joint attention and common knowledge? On the one hand, the relation seems tight: the easiest and most reliable way of knowing something in common with another is for you and that other to be attentively aware of what you are together experiencing. On the other hand, they couldn’t seem further apart: joint attention is a mere perceptual phenomena that infants are capable of engaging in from nine months of age, whereas common knowledge is a cognitive (...) phenomenon involving (so it seems) complex, overlapping metarepresentational states that require the kind of sophisticated mindreading skills that developmental psychology has shown to be beyond the capabilities of young children. In 'The Shared World: Perceptual Common Knowledge, Demonstrative Communication, and Shared Social Space', Axel Seemann attempts, inter alia, to makensense of this conundrum. (shrink)

Our aim in this paper is to present the distinct ways in which Wolff, Baumgarten, and Kant understand the relationship between necessitation, constraint, and reluctant action in an effort to illustrate the subtle ways in which their conceptions of obligation differ from each another. Whereas Wolff conceives of natural or moral obligation as incompatible with constraint, Baumgarten holds that constraint and reluctant action are, in some instances, compatible with natural obligation. Kant departs from Baumgarten by conceiving of obligation as necessarily (...) involving constraint: as Kant’s reply to Schiller’s famous objection reveals, obligation must take on the character of constraint to reluctant action on account of the fact that human beings possess inclinations that always threaten to impel them in directions that oppose morality.

This paper generalizes rationalizability of a choice function by a single acyclic binary relation to rationalizability by a set of such relations. Rather than selecting those options in a menu that are maximal with respect to a single binary relation, a weakly pseudo-rationalizable choice function selects those options that are maximal with respect to at least one binary relation in a given set. I characterize the class of weakly pseudo-rationalizable choice functions in terms of simple functional properties. This result also (...) generalizes Aizerman and Malishevski's characterization of pseudo-rationalizable choice functions, that is, choice functions rationalizable by a set of total orders. (shrink)

Using William Shakespeare’s Hamlet and the play-within-the play, The Murder of Gonzago, as a case study, this essay argues that theatrical utterances constitute a special case of language usage not previously elucidated: the utterance of a statement with propositional content in theatre functions as an event. In short, the propositional content of a particular p (e.g. p1, p2, p3 …), whether or not it is true, is only understood—and understood to be true—if p1 is uttered in a particular time, place, (...) and situation (i.e. during a theatrical event); otherwise, the propositional content in those theatrical utterances can either be false or contingently true.

I show that the common reading of Thomson, that she argues by analogy for the conclusion that abortion is permissible, is mistaken. The correct reading of Thomson is that she argues by counterexample, showing that arguments against abortion are unsound. The remainder of the paper highlights the lessons learned from Thomson once we read her aright.

What exactly do we mean when we refer to disability as a social construction? How viable are the justifications for this? These questions are explored in this paper. To this end, various theories that are influential in German-language disability studies are examined and criticised. These include Oliver's social model, furthermore the "Thomas theorem", Berger and Luckmann's sociology of knowledge, Foucault's discourse theory and Waldschmidt's theory. Subsequently, social constructivist approaches of Watzlawick and Gergen and Gergen are discussed. It is shown that (...) a relativistic understanding of social construction can be used to deny facticity and thus undermines the foundations of scientific knowledge. This danger must be taken seriously when defending the scientificity of disability studies. (shrink)

Supra-Bayesianism is the Bayesian response to learning the opinions of others. Probability pooling constitutes an alternative response. One natural question is whether there are cases where probability pooling gives the supra-Bayesian result. This has been called the problem of Bayes-compatibility for pooling functions. It is known that in a common prior setting, under standard assumptions, linear pooling cannot be nontrivially Bayes-compatible. We show by contrast that geometric pooling can be nontrivially Bayes-compatible. Indeed, we show that, under certain assumptions, geometric and (...) Bayes-compatible pooling are equivalent. Granting supra-Bayesianism its usual normative status, one upshot of our study is thus that, in a certain class of epistemic contexts, geometric pooling enjoys a normative advantage over linear pooling as a social learning mechanism. We discuss the philosophical ramifications of this advantage, which we show to be robust to variations in our statement of the Bayes-compatibility problem. (shrink)

Freedom can be seen as individual’s capacity to choose between alternatives. As such, it stands in a dialectical relationship to its environment that both imposes constraints on freedom and allows carrying it out. Yet if we see liberty as freedom’s social accommodation, how would freedom shape liberty, and how would liberty accommodate freedom? As a capacity for choice, freedom is formal. Negative liberty, or freedom from, protects this capacity yet does not give it content. To make freedom meaningful, its societal (...) accommodation has ensure that the choice can be carried out – in terms of accessing alternatives, understand them, and making informed choices. The paper, using the tools provided by the Hegelian philosophy and by information theory, explores the concept of liberty as an enabler of freedom and the role of knowledge in its enablement. This exploration leads us to specific positive rights that are necessary to make freedom meaningful. (shrink)

An aspect of Peirce’s thought that may still be underappreciated is his resistance to what Levi calls _pedigree epistemology_, to the idea that a central focus in epistemology should be the justification of current beliefs. Somewhat more widely appreciated is his rejection of the subjective view of probability. We argue that Peirce’s criticisms of subjectivism, to the extent they grant such a conception of probability is viable at all, revert back to pedigree epistemology. A thoroughgoing rejection of pedigree in the (...) context of probabilistic epistemology, however, _does_ challenge prominent subjectivist responses to the problem of the priors. (shrink)

This paper argues that Kant’s concept of ‘respect’ for the moral law has roots in Adam Smith’s concept of ‘regard’ for the general rules of conduct, which was translated as Achtung in the first German translation of the Theory of Moral Sentiments. After illustrating that Kant’s technical understanding of respect appeared relatively late in his intellectual development, I argue that Kant’s concept of respect and Smith’s concept of regard share a basic similarity: they are both a single complex phenomenon with (...) two core aspects, namely an attitude and a feeling. I then suggest that the concept of regard offered Kant a way to deal a problem concerning moral motivation that he was trying to solve at the time he likely first read Smith. I conclude by drawing some implications from the account I have offered for our understanding of Kant’s relation to Smith more generally. (shrink)

In the face of an impossibility result, some assumption must be relaxed. The Mere Addition Paradox is an impossibility result in population ethics. Here, I explore substantially weakening the decision-theoretic assumptions involved. The central finding is that the Mere Addition Paradox persists even in the general framework of choice functions when we assume Path Independence as a minimal decision-theoretic constraint. Choice functions can be thought of either as generalizing the standard axiological assumption of a binary “betterness” relation, or as providing (...) a general framework for a normative (rather than axiological) theory of population ethics. Path Independence, a weaker assumption than typically (implicitly) made in population ethics, expresses the idea that, in making a choice from a set of alternatives, the order in which options are assessed or considered is ethically arbitrary and should not affect the final choice. Since the result establishes a conflict between the relevant ethical principles and even very weak decision-theoretic principles, we have more reason to doubt the ethical principles. (shrink)

Epistemic states of uncertainty play important roles in ethical and political theorizing. Theories that appeal to a “veil of ignorance,” for example, analyze fairness or impartiality in terms of certain states of ignorance. It is important, then, to scrutinize proposed conceptions of ignorance and explore promising alternatives in such contexts. Here, I study Lerner’s probabilistic egalitarian theorem in the setting of imprecise probabilities. Lerner’s theorem assumes that a social planner tasked with distributing income to individuals in a population is “completely (...) ignorant” about which utility functions belong to which individuals. Lerner models this ignorance with a certain uniform probability distribution, and shows that, under certain further assumptions, income should be equally distributed. Much of the criticism of the relevance of Lerner’s result centers on the representation of ignorance involved. Imprecise probabilities provide a general framework for reasoning about various forms of uncertainty including, in particular, ignorance. To what extent can Lerner’s conclusion be maintained in this setting? (shrink)

This thesis develops an account of ethics called the Linguistic Perspective, which is realist in a practical, non-theoretical sense, and is rooted Wittgenstein’s 'On Certainty'. On this account, normativity is intrinsic to human action and language; the norms of ethics are the logical limits of the most basic, unassailable concepts that practical reasoning requires for intelligibility. Part I lays the groundwork for this account by developing a Tractarian Reading of 'On Certainty'. Here, I contend that 'On Certainty' is primarily concerned (...) with the logical requirements and limits of language, and like the 'Tractatus' it develops these concerns in a realist direction. 'On Certainty', I argue, does so by advancing three key claims about logic: Everything descriptive of a language-game is part of logic; the boundary between logical and empirical propositions is not sharp; logic is founded on action. I investigate these claims, with particular emphasis on how natural human reactions provide logical conditions for the possibility of language. Hinge propositions, I argue, are rooted in these reactions; they point us to the limits of intelligibility of our concepts, though these limits are vague and inarticulable. In Part II, I discuss the practical syllogism and its validity. I argue that practical reasoning is distinct from theoretical reasoning and embodies a different standard of logical validity for inference. This standard is not strict and narrow, but creative and wide open; furthermore, it is an intrinsically ethical standard. Then, I advance my Linguistic Perspective on ethics, according to which human reactions provide the conditions for ethical normativity, just as they do for language. I argue that we can access ethical norms by reflecting on those linguistic concepts that are rooted in the most basic patterns of action, and by identifying the norms of behaviour that ensure the development of those concepts without contradiction.

There has been recent discussion of a puzzle posed by emotions that are backward looking. Though our emotions commonly diminish over time, how can they diminish fittingly if they are an accurate appraisal of an event that is situated in the past? Agnes Callard (2017) has offered a solution by providing an account of anger in which anger is both backwards looking and resolvable, yet her account depends upon contrition to explain anger’s fitting diminishment. My aim is to explain how (...) anger can fittingly diminish even when there is lack of contrition. I propose a permissivism about fittingness by showing that both anger and compassion are fitting responses to blameworthy behaviour. I argue that anger is rendered fitting because it accurately appraises the behaviour, whereas compassion becomes fitting as a valuational response to what the behaviour reveals about the lived experience of the offender. I then respond to some worries my account raises, and I clarify details of my account to show that it is not unrealistic to the way some of our anger actually does diminish. I end with a proposal that our anger can fittingly diminish through the act of forgiveness when compassion is not a forthcoming affective response. (shrink)

In this paper, we explore how a conversational theory of moral responsibility can provide illuminating resources for building a theory about the nature and norms of moral forgiveness.

This chapter offers an account of Crusius’ conception of freedom. In the first part of the chapter I sketch Crusius’ understanding of ‘Thelematology’ or ‘science of the will’ and his conception of the will itself. In the second part of the paper I provide an account of Crusius’ conception of freedom of the will and I focus on two topics: his understanding of freedom as self-determination and his conception of free choice. Contrary to how some of the secondary literature portrays (...) his view, I argue that freedom of the will, for Crusius, is not best described as the freedom to choose otherwise or liberty of indifference. On the contrary, Crusius argues that free choice is rarely indifferent to its choices and is most often strongly inclined towards certain ends that free choice must overcome and choose against.

Whataboutism is een strategie waarbij op een beschuldiging wordt gereageerd met een wedervraag die eveneens een beschuldiging impliceert, waardoor de oorspronkelijke vraag eerder wordt ontweken dan beantwoord. Het is een effectieve methode om de aandacht te verplaatsen naar een andere situatie door een vergelijkbaar, dan wel onvergelijkbaar, contrast te bieden, waardoor de beschuldigde het eigen gedrag probeert te rechtvaardigen en verantwoordelijkheid probeert te ontlopen. Maar niet alle vormen van whataboutism impliceren echter een drogredenering, noch worden ze altijd verkeerd toegepast. Het (...) contrast dat voortkomt uit de vraag ‘what about’ kan dan een cruciale bijdrage leveren aan een situatie die een verdere kritische analyse vereist, en daarmee de geloofwaardigheid van de argumentatie versterken.

A very influential idea in the epistemology of modality is that we acquire knowledge of metaphysical modality through knowledge of essence. As a consequence, the epistemology of essence becomes crucial in the attempt to answer the question of how we come to know modal propositions. In this paper I investigate Lowe’s and Hale’s approach to the epistemology of essence and argue that both of them remain in a crucial, structural sense incomplete. Systematizing this criticism against Lowe and Hale, I then (...) break down desiderata of what I call a structurally complete picture of the epistemology of essence. Finally, I discuss Husserl’s epistemology of essence and defend it against a notorious objection. However, Husserl’s approach also seems to remain incomplete, due to its appeal to imagination, which operates on the basis of background assumptions that are themselves in need of justification. I indicate, however, that a Husserlian theory of intuitive awareness of universals might supply us with (direct) justification of these background assumptions and, hence, that we might be able to paint a structurally complete picture of the epistemology of essence with Husserlian means.

Could the concept of 'evil' apply to AI? Drawing on PF Strawson's framework of reactive attitudes, this paper argues that we can understand evil as involving agents who are neither fully inside nor fully outside our moral practices. It involves agents whose abilities and capacities are enough to make them morally responsible for their actions, but whose behaviour is far enough outside of the norms of our moral practices to be labelled 'evil'. Understood as such, the paper argues that, when (...) it comes to AI and evil, we have more to fear from semi-autonomous, hybrid agents: agents who have enough of a capacity to operate within a minimal form of human practices of participation and responsibility, yet remain partially outside of it, capable of acting from outside the parameters of ordinary interactions in certain circumstances, perhaps sometimes for reasons unknown.

This paper explores the question of what logic is not. It argues against the wide spread assumptions that logic is: a model of reason; a model of correct reason; the laws of thought, or indeed is related to reason at all such that the essential nature of the two are crucially or essentially co-illustrative. I note that due to such assumptions, our current understanding of the nature of logic itself is thoroughly entangled with the nature of reason. I show that (...) most arguments for the presence of any sort of essential re- lationship between logic and reason face intractable problems and demands, and fall well short of addressing them. These arguments include those for the notion that logic is normative for reason (or that logic and correct reason are in some way the same thing), that logic is some sort of description of correct reason and that logic is an abstracted or idealised version of correct reason. A strong version of logical realism is put forward as an alternative view, and is briefly explored. (shrink)

We provide a new interpretation of Zeno’s Paradox of Measure that begins by giving a substantive account, drawn from Aristotle’s text, of the fact that points lack magnitude. The main elements of this account are (1) the Axiom of Archimedes which states that there are no infinitesimal magnitudes, and (2) the principle that all assignments of magnitude, or lack thereof, must be grounded in the magnitude of line segments, the primary objects to which the notion of linear magnitude applies. Armed (...) with this account, we are ineluctably driven to introduce a highly constructive notion of (outer) measure based exclusively on the total magnitude of potentially infinite collections of line segments. The Paradox of Measure then consists in the proof that every finite or potentially infinite collection of points lacks magnitude with respect to this notion of measure. We observe that the Paradox of Measure, thus understood, troubled analysts into the 1880’s, despite their knowledge that the linear continuum is uncountable. The Paradox was ultimately resolved by Borel in his thesis of 1893, as a corollary to his celebrated result that every countable open cover of a closed line segment has a finite sub-cover, a result he later called the “First Fundamental Theorem of Measure Theory.” This achievement of Borel has not been sufficiently appreciated. We conclude with a metamathematical analysis of the resolution of the paradox made possible by recent results in reverse mathematics. (shrink)

I argue that one in particular of CrispinWright’s attempts to capture our common or intuitive concepts of objectivity, warrant, and other associated notions, relies on an ambiguity between a given constructivist reading of the concepts and at least one other, arguablymore ‘ordinary’, version of the notions he tries to accommodate. I do this by focusing on one case in point, and concluding with a brief argument showing how this case generalises. I demonstrate why this ambiguity is unacceptable and also that (...) its resolution undermines the aim it serves: to account for and accommodate our ordinary conception of (at least) objectivity, warrant (or justication) and truth.

In this paper I argue that Kant’s psychology of moral motivation has less in common with Hutcheson’s view than interpreters have traditionally thought. I first offer an interpretation of the role that feeling, desire, and cognition play in Kant’s account of moral action. I then outline the essential features of Hutcheson’s understanding of desire before arguing that although Kant and Hutcheson share the trivial similarity that even moral action springs from a desire, Kant conceives of the desire at the root (...) of moral action as qualitatively different from all other desires in a number of important ways.

Traditionally, species have been treated as classes. In fact they may be considered individuals. The logical term “individual” has been confused with a biological synonym for “organism.” If species are individuals, then: 1) their names are proper, 2) there cannot be instances of them, 3) they do not have defining properties, 4) their constituent organisms are parts, not members. “ Species " may be defined as the most extensive units in the natural economy such that reproductive competition occurs among their (...) parts. Species are to evolutionary theory as firms are to economic theory: this analogy resolves many issues, such as the problems of “reality” and the ontological status of nomenclatorial types. (shrink)

Dion is a full-bodied man. Theon is that part of him which consists of all of him except his left foot. What becomes of Dion and Theon when Dion’s left foot is amputated? Employing the doctrine of sortal essentialism, I defend a surprising answer last defended by Chrysippus: that Dion survives while the seemingly unscathed Theon perishes. For replies to critics, see my publications of 1997 and (especially) 2004.

In this chapter I offer an account of the nature, scope, and significance of Wolff’s claim that human beings have a duty to cognize moral good and evil. I illustrate that Wolff conceives of this duty as requiring that human beings both acquire distinct cognition of good and evil as well as avoid ignorance and error. Although Wolff intends for the duty to be quite demanding, he restricts its scope by, among other things, claiming it primarily concerns those who have (...) the skills, circumstances, and opportunity to acquire such cognition. Wolff calls these individuals the ‘inventors’ of the truths of morality and he considers himself to be such an inventor. I argue that part of the significance of this duty lies in the fact that Wolff conceives of himself as living up to it by writing the German Ethics, thereby sharing the knowledge he has ‘invented’ with others.

Many philosophers assume that, when making moral decisions under uncertainty, we should choose the option that has the greatest expected moral value, regardless of how risky it is. But their arguments for maximizing expected moral value do not support it over rival, risk-averse approaches. In this paper, I present a novel argument for maximizing expected value: when we think about larger series of decisions that each decision is a part of, all but the most risk-averse agents would prefer that we (...) consistently choose the option with the highest expected value. To the extent that what we choose on a given occasion should be guided by the entire series of choices we prefer, then on each occasion, we should choose the option with the highest expected moral value.

Scholars, journalists, and activists working on climate change often distinguish between “individual” and “structural” approaches to decarbonization. The former concern choices individuals can make to reduce their “personal carbon footprint” (e.g., eating less meat). The latter concern changes to institutions, laws, and other social structures. These two approaches are often framed as oppositional, representing a mutually exclusive forced choice between alternative routes to decarbonization. After presenting representative samples of this oppositional framing of individual and structural approaches in environmental communication, we (...) identify four problems with oppositional thinking and propose five ways to conceive of individual and structural reform as symbiotic and interdependent.

In this paper I propose three steps to overcome the force-content dichotomy and dispel the Frege point. First, we should ascribe content to force indicators. Through basic assertoric and directive force indicators such as intonation, word order and mood, a subject presents its position of theoretical or practical knowledge of a state of affairs as a fact, as something that is the case, or as a goal, as something to do. Force indicators do not operate on truth- or satisfaction evaluable (...) entities as on the traditional view, but complete and unify them. Second, higher-level acts such as interrogative, logical and fictional acts create higher-level unities that may suspend commitment to the assertions and directions they operate on. But they do not cancel their force, but transfer the meaning of force indicators into the new unities they create. For example, in the context of asking a theoretical or practical question, the assertoric or directive force indicator now presents the kind of knowledge the subject is seeking. Third, the Frege point conflates different varieties of force. We neither need Frege’s assertion sign, nor Hare’s neustic, nor Hanks’s cancellation sign, but only ordinary force indicators and interrogative, logical and fictional markers. Propositions are not forceless contents to which a subject commits by forceful acts, but forceful acts put forward by higher-level acts which may suspend commitment to them. (shrink)
