In this paper I argue for an association between impurity and explanatory power in contemporary mathematics. This proposal is defended against the ancient and influential idea that purity and explanation go hand-in-hand (Aristotle, Bolzano) and recent suggestions that purity/impurity ascriptions and explanatory power are more or less distinct (Section 1). This is done by analyzing a central and deep result of additive number theory, Szemerédi’s theorem, and various of its proofs (Section 2). In particular, I focus upon the radically impure (...) (ergodic) proof due to Furstenberg (Section 3). Furstenberg’s ergodic proof is striking because it utilizes intuitively foreign and infinitary resources to prove a finitary combinatorial result and does so in a perspicuous fashion. I claim that Furstenberg’s proof is explanatory in light of its clear expression of a crucial structural result, which provides the “reason why” Szemerédi’s theorem is true. This is, however, rather surprising: how can such intuitively different conceptual resources “get a grip on” the theorem to be proved? I account for this phenomenon by articulating a new construal of the content of a mathematical statement, which I call structural content (Section 4). I argue that the availability of structural content saves intuitive epistemic distinctions made in mathematical practice and simultaneously explicates the intervention of surprising and explanatorily rich conceptual resources. Structural content also disarms general arguments for thinking that impurity and explanatory power might come apart. Finally, I sketch a proposal that, once structural content is in hand, impure resources lead to explanatory proofs via suitably understood varieties of simplification and unification (Section 5).

It is well-known that the global structure of every space-time model for relativistic cosmology is observationally underdetermined. In order to alleviate the severity of this underdetermination, it has been proposed that we adopt the Cosmological Principle because the Principle restricts our attention to a distinguished class of space-time models (spatially homogeneous and isotropic models). I argue that, even assuming the Cosmological Principle, the topology of space remains observationally underdetermined. Nonetheless, I argue that we can muster reasons to prefer various topological (...) properties over others. In particular, I favor the adoption of multiply connected universe models on grounds of (i) simplicity, (ii) Machian considerations, and (iii) explanatory power. We are able to appeal to such grounds because multiply connected topologies open up the possibility of finite universe models (consistent with our best data), which in turn avoid thorny issues concerning the postulation of an actually infinite universe.

As robots slip into more domains of human life-from the operating room to the bedroom-they take on our morally important tasks and decisions, as well as create new risks from psychological to physical. This book answers the urgent call to study their ethical, legal, and policy impacts.

These are my materials (a short precis, and replies to John MacFarlane, Mitchell Green, Ryan Wasserman, and Anthony Bigg and Kristie Miller) for a symposium on my book, _The Open Future: Why Future Contingents are All False_ (OUP, 2021) in *Analytic Philosophy*.

The deep influence of affectivity on learning is now widely acknowledged (Keefer et al., 2018; Sánchez-Álvarez et al., 2021). For instance, it has been shown that affect influences key learning-relevant processes, such as motivation, perception, behavior, and critical thinking (Izard, 2002; Mayer & Salovey, 1997). Evidence also shows that emotion and mood strongly influence attention, which in turn drives learning and memory (Elbertson et al., 2010; Elias et al., 1997). Intersubjective phenomena, such as the degree of affection and respect between (...) child and teacher, also affect the child’s learning processes, academic outcomes, and brain development (Kusché & Greenberg, 2006; Ryan & Patrick, 2001). However, the relevant literature is not paying attention to increasing evidence showing that affective phenomena are rooted in interoceptive and homeostatic self- and co-regulatory processes within and between people’s living bodies (Barrett, 2017; Carvalho & Damasio, 2021; Craig, 2015, 2018; Fotopoulou et al., 2022; Fotopoulou & Tsakiris, 2017; Seth & Friston, 2016). In this theoretical chapter, we explore this connection and its importance for learning. We argue that affective experience plays a fundamental role in learning, and that affective experience is rooted in the homeostatic self-/co-regulation of living bodies. Therefore, the homeostatic self-/co-regulation of living bodies plays a fundamental role in learning. In other words, there is an intra- and interpersonal somatic dimension of learning that demands explicit consideration in educational contexts. In this way, we aim to contribute to an understanding of learning and education that moves away from an individualistic, brain-centered information-processing conception toward one centered on sentient, interdependent living bodies.

Most accounts of cognitive scaffolding focus on ways that external structure can support or augment an agent’s cognitive capacities. We call cases where the interests of the user are served benign scaffolding and argue for the possibility and reality of hostile scaffolding. This is scaffolding which depends on the same capacities of an agent to make cognitive use of external structure as in benign cases, but that undermines or exploits the user while serving the interests of another agent. We develop (...) criteria for scaffolding being hostile and show by reference to examples including the design features of electronic gambling machines and casino management systems that hostile scaffolding exists and can be highly effective. In cases where the scaffolding is deep and permits the offloading of significant cognitive work, hostile scaffolding exploitatively manipulates cognitive processing itself. Given the extent of human reliance on scaffolding this is an important and neglected vulnerability. [This is an updated version of the paper, added in February 2023.]. (shrink)

Given that conspiracies exist, can we be justified in dismissing conspiracy theories without concerning ourselves with specific details? I answer this question by focusing on contrarian conspiracy theories, theories about conspiracies that conflict with testimony from reliable sources of information. For example, theories that say the CIA masterminded the assassination of John F. Kennedy, 9/11 was an inside job, or the Freemasons are secretly running the world are contrarian conspiracy theories. When someone argues for a contrarian conspiracy theory, their options (...) are to appeal to eyewitness testimony, incriminating documents, photographs, audio recordings, video recordings, allegedly scientific evidence, anomalies, or considerations of cui bono (who benefits). Most laypeople don’t know how to adequately respond to arguments for contrarian conspiracy theories, but this doesn’t mean that it’s dogmatic to reject them. I argue that many laypeople are defeasibly justified in rejecting a variety of contrarian conspiracy theories based on testimony and this justification is rarely defeated by arguments for contrarian conspiracy theories even if we don’t know how to respond to these arguments.

When are morally good actions beautiful, when indeed they are? In this paper, it is argued that morally good actions are beautiful when they appear to express the deep or true self, and in turn tend to give rise to an emotion which is characterised by feelings of being moved, unity, inspiration, and meaningfulness, inter alia. In advancing the case for this claim, it is revealed that there are additional sources of well-formedness in play in the context of moral beauty (...) in addition to those that have tended to be focused on to date: one which is connected to imagining a deep location for the goodness concerned, and another which is connected to imagining that the goodness stems from capacities which are essential to the person.

Which traits are beautiful? And is their beauty perceptual? It is argued that moral virtues are partly beautiful to the extent that they tend to give rise to a certain emotion— ecstasy—and that compassion tends to be more beautiful than fair-mindedness because it tends to give rise to this emotion to a greater extent. It is then argued, on the basis that emotions are best thought of as a special, evaluative, kind of perception, that this argument suggests that moral virtues (...) are partly beautiful to the extent that they tend to give rise to a certain kind of evaluative perceptual experience.

What is the nature of the concept BEAUTY? Does it differ fundamentally from nearby concepts such as PRETTINESS? It is argued that BEAUTY, but not PRETTINESS, is a dual-character concept. Across a number of contexts, it is proposed that BEAUTY has a descriptive sense that is characterised by, inter alia, having intrinsically pleasing appearances; and a normative sense associated with deeply-held values. This account is supported across two, pre-registered, studies (N=500), and by drawing on analysis of corpus data. It is (...) suggested that this can help to explain why beauty, unlike prettiness, is thought to be deep in both the sense of being important, and in the sense of being less closely tied to sensory surfaces.

According to the most important objection to the existence of moral beauty, true judgements of moral beauty are not possible as moral judgements require being motivated to act in line with the moral judgement made, and judgements of beauty require not being motivated to act in any way. Here, I clarify the argument underlying the objection, and show that it does not show that moral beauty does not exist. I present two responses: namely, that the beauty of moral beauty does (...) not lie in the moral goodness per se (the “adjacent properties” response); and that only a dispositional motivation to act is required for the moral judgements that are typically made as part of judgements of moral beauty, whereas aesthetic judgements only rule out state motivations to act (the “equivocation of motivation required” response). In addressing the objection, I show how moral beauty is consistent with disinterestedness, and so should be accepted more widely; and also clarify where the beauty in moral beauty resides, and how the moral-aesthetic distinction should be drawn.

In this article, robust evidence is provided showing that an individual’s moral character can contribute to the aesthetic quality of their appearance, as well as being beautiful or ugly itself. It is argued that this evidence supports two main conclusions. First, moral beauty and ugliness reside on the inside, and beauty and ugliness are not perception-dependent as a result; and, second, aesthetic perception is affected by moral information, and thus moral beauty and ugliness are on the outside as well.

Why are moral actions beautiful, when indeed they are? This paper assesses the view, found most notably in Schiller, that moral actions are beautiful just when they present the appearance of freedom by appearing to be the result of internal harmony (the Schillerian Internal Harmony Thesis). I argue that while this thesis can accommodate some of the beauty involved in contrasts of the ‘continent’ and the ‘fully’ virtuous, it cannot account for all of the beauty in such contrasts, and so (...) needs to be weakened considerably (to the Internal Harmony Thesis). To account for the remaining beauty that cannot be fully accommodated even by this revised thesis, as well as the beauty contained in contrasts that involve agents who experience internal conflict as a result of being sensitive to different sources of moral value to an appropriate extent, a number of further theses need to be posited: namely, that the beauty of some moral actions is to be accommodated in terms of internal disharmony (the Internal Disharmony Thesis), and in terms of a felt harmony between the appreciator of the action and the executor of the action (the Affective Harmony Thesis). As such, in contrast to Schiller, I suggest that we need to take a pluralist and context-sensitive approach to accommodating the beauty of moral actions. (shrink)

Inspired by Helen Longino’s ‘critical contextual empiricism’, in this paper I argue that art arises from social epistemic procedures that encompass both aesthetic functions and institutional practices. Within these procedures, aesthetic functions are developed, validated, and enforced through institutional practices, rather than being solely tied to the artistic outcomes of those practices. I call this approach ‘critical contextual aestheticism’.

In this article, an account of the architecture of the cognitive contamination system is offered, according to which the contamination system can generate contamination represen- tations in circumstances that do not satisfy the norms of contamination, including in cases of mere visual contact with disgusting objects. It is argued that this architecture is important for explaining the content, logic, distribution, and persistence of maternal impression beliefs – according to which fetal defects are caused by the pregnant mother’s experiences and actions (...) – which in turn provide important evidence of the architecture of the cognitive contamination system.

I argue that the main existing accounts of the relationship between the beauty of environmental entities and their moral standing are mistaken in important ways. Beauty does not, as has been suggested by optimists, confer intrinsic moral standing. Nor is it the case, as has been suggested by pessimists, that beauty at best provides an anthropocentric source of moral standing that is commensurate with other sources of pleasure. I present arguments and evidence that show that the appreciation of beauty tends (...) to cause a transformational state of mind that is more valuable than mere pleasure, but that leads us to falsely represent beautiful entities as being sentient and, in turn, as having intrinsic moral standing. To this extent, beauty is not, then, a source of intrinsic moral standing; it’s a source of a more important anthropocentric value than has hitherto been acknowledged. (shrink)

I offer the first sustained defence of the claim that ugliness is constituted by the disposition to disgust. I advance three main lines of argument in support of this thesis. First, ugliness and disgustingness tend to lie in the same kinds of things and properties (the argument from ostensions). Second, the thesis is better placed than all existing accounts to accommodate the following facts: ugliness is narrowly and systematically distributed in a heterogenous set of things, ugliness is sometimes enjoyed, and (...) ugliness sits opposed to beauty across a neutral midpoint (the argument from proposed intensions). And third, ugliness and disgustingness function in the same way in both giving rise to representations of contamination (the argument from the law of contagion). In making these arguments, I show why prominent objections to the thesis do not succeed, cast light on some of the artistic functions of ugliness, and, in addition, demonstrate why a dispositional account of disgustingness is correct, and present a novel problem for warrant-based accounts of disgustingness (the ‘too many reasons’ problem).

One important task of metaphysics is to answer the question of what it is for an object to exist. The first part of this book offers a systematic reconstruction and critique of contemporary views on existence. The upshot of this part is that the contemporary debate has reached an impasse because none of the considered views is able to formulate a satisfactory answer to this fundamental metaphysical question. The second part reconstructs Thomas Aquinas’s view on existence (esse) and argues that (...) it contributes a new perspective which allows us to see why the contemporary debate has reached this impasse. It has come to this point because it has taken a premise for granted which Aquinas’s view rejects, namely, that the existence of an object consists in something’s having a property. A decisive contribution of Aquinas’s theory of esse is that it makes use of the ideas of metaphysical participation and composition. In this way, it can be explained how an object can have esse without being the case that esse is a property of it. This book brings together a reconstruction from the history of philosophy with a systematic study on existence and is therefore relevant for scholars interested in contemporary or medieval theories of existence.

It is widely held that agent-neutral consequentialism is incompatible with deontic constraints. Recently, Kieran Setiya has challenged this orthodoxy by presenting a form of agent-neutral consequentialism that he claims can capture deontic constraints. In this reply, we argue against Setiya's proposal by pointing to features of deontic constraints that his account fails to capture.

Conspiracy theories are rather a popular topic these days, and a lot has been written on things like the meaning of _conspiracy theory_, whether it’s ever rational to believe conspiracy theories, and on the psychology and demographics of people who believe conspiracy theories. But very little has been said about why people might be led to posit conspiracy theories in the first place. This paper aims to fill this lacuna. In particular, I shall argue that, in open democratic societies, citizens (...) justifiably presuppose that the epistemic authorities—journalists, academics, scientists, and so on—are engaged in a good faith pursuit of the truth. This presupposition generates certain normative expectations on the behaviors of the epistemic authorities—they ought to be open to new evidence, possess a healthy degree of skepticism, be willing to engage with opponents, and so on. So, when an epistemic authority is presented with some putatively anomalous data or an alternative hypothesis for some event or phenomena, people expect the epistemic authority to respond in a way that is consonant with these norms. In some instances, however, the epistemic authorities do not respond in this way and instead are dogmatic, dismissive, and engage in _ad hominem_. From the point of view of the citizen, there’s a tension here between how the epistemic authorities ought to behave and how they have, in fact, behaved which is best resolved either by taking the epistemic authorities less seriously or by positing a conspiracy theory. Put another way, the failure of the epistemic authorities to adhere to the norms by which we take them to be governed when presented with apparent anomalies or alternative hypotheses is one reason for which one might initially posit a conspiracy theory.

Luck egalitarians argue that distributive justice should be understood in terms of our capacity to be responsible for our choices. Both proponents and critics assume that the theory must rely on a comprehensive conception of responsibility. I respond to luck egalitarianism’s critics by developing a political conception of responsibility that remains agnostic on the metaphysics of free choice. I construct this political conception by developing a novel reading of John Rawls’ distinction between the political and the comprehensive. A surprising consequence (...) is that many responsibility-based objections to luck egalitarianism turn out to be objections to Rawls’ political liberalism as well. (shrink)

As well as disagreeing about how much one should donate to charity, moral theories also disagree about where one should donate. In light of this disagreement, how should the morally uncertain philanthropist allocate her donations? In many cases, one intuitively attractive option is for the philanthropist to split her donations across all of the charities that are recommended by moral views in which she has positive credence, with each charity’s share being proportional to her credence in the moral theories that (...) recommend that particular charity. Despite the fact that something like this approach is already being used by real-world philanthropists to distribute billions of dollars of donations, it is not supported by any of the approaches to moral uncertainty that have been proposed thus-far in the philosophical literature. In this paper, we will develop a bargaining-based approach to moral uncertainty that honors the proportionality intuition in favor of splitting one’s donations. We also show how this bargaining-based approach has several further advantages over the best alternative proposals. (shrink)

This paper focuses on a recently articulated, emergentist conception of ethical naturalism and its commitment to causal efficacy, or the idea that moral properties have causal powers, along with its supporting commitment to moral causation. After I reconstruct the theory, I explain how it offers some interesting theoretical benefits to moral realists in virtue of its commitment to causal efficacy. Then, after locating some examples of moral causation in support of this commitment, I present and respond to five objections to (...) such causation, which all threaten to undermine this support. Lastly, I consider a very serious problem that the theory faces in virtue of positing emergent moral properties as responsible for moral causation – namely, the problem of downward moral causation. I describe this problem in detail and argue that, as it stands, it does not spell doom for the theory. (shrink)

In this chapter, I argue that the films of Andrei Tarkovsky are particularly suitable for inducing feelings of the numinous. This suitability is a formal rather than semantic feature of his films, and is tied indelibly to what film scholars call ‘suture’. I with a summary of what film theorists mean by ‘suture’, before providing a principled defence of the Merleau-Pontian suture theory outlined by George Butte. Second, I will demonstrate that, in spite of the strength of Butte’s formulation, the (...) numinousness of Tarkovsky’s films pose an analytical challenge to his suture theory. Finally, I will then provide my own extension of Butte’s suture theory, arguing that, by virtue of the formal properties they possess, we encounter Tarkovsky’s films more like religious objects than ordinary films. The tenor of these encounters is why Tarkovsky’s films are appropriate loci for feelings of the numinous. (shrink)

According to an argument that I will call the argument from loose lips, we can safely reject certain notorious conspiracy theories because they posit conspiracies that would be nearly impossible to keep secret. I distinguish between three versions of this argument: the epistemic argument, the alethic argument, and the statistical argument. I, then, discuss several limitations of the argument from loose lips. The first limitation is that only the statistical argument can be applied to new conspiracy theories. The second limitation (...) is that no version of the argument suffices to rule out the existence of small initial conspiracies that have no need to add further conspirators. The third limitation is that no version of the argument is dialectically efficacious in the context of arguing with the relevant conspiracy theorists because nothing is said to address the alleged evidence that they cite.

This paper develops a novel problem for representationalism (also known as "intentionalism"), a popular contemporary account of perception. We argue that representationalism is incompatible with supervaluationism, the leading contemporary account of vagueness. The problem generalizes to naive realism and related views, which are also incompatible with supervaluationism.

Recently, philosophers have turned their attention to the question, not when a given agent is blameworthy for what she does, but when a further agent has the moral standing to blame her for what she does. Philosophers have proposed at least four conditions on having “moral standing”: -/- 1. One’s blame would not be “hypocritical”. 2. One is not oneself “involved in” the target agent’s wrongdoing. 3. One must be warranted in believing that the target is indeed blameworthy for the (...) wrongdoing. 4. The target’s wrongdoing must some of “one’s business”. -/- These conditions are often proposed as both conditions on one and the same thing, and as marking fundamentally different ways of “losing standing.” Here I call these claims into question. First, I claim that conditions (3) and (4) are simply conditions on different things than are conditions (1) and (2). Second, I argue that condition (2) reduces to condition (1): when “involvement” removes someone’s standing to blame, it does so only by indicating something further about that agent, viz., that he or she lacks commitment to the values that condemn the wrongdoer’s action. The result: after we clarify the nature of the non-hypocrisy condition, we will have a unified account of moral standing to blame. Issues also discussed: whether standing can ever be regained, the relationship between standing and our "moral fragility", the difference between mere inconsistency and hypocrisy, and whether a condition of standing might be derived from deeper facts about the "equality of persons".

An early, very preliminary edition of this book was circulated in 1962 under the title Set-theoretical Structures in Science. There are many reasons for maintaining that such structures play a role in the philosophy of science. Perhaps the best is that they provide the right setting for investigating problems of representation and invariance in any systematic part of science, past or present. Examples are easy to cite. Sophisticated analysis of the nature of representation in perception is to be found already (...) in Plato and Aristotle. One of the great intellectual triumphs of the nineteenth century was the mechanical explanation of such familiar concepts as temperature and pressure by their representation in terms of the motion of particles. A more disturbing change of viewpoint was the realization at the beginning of the twentieth century that the separate invariant properties of space and time must be replaced by the space-time invariants of Einstein's special relativity. Another example, the focus of the longest chapter in this book, is controversy extending over several centuries on the proper representation of probability. The six major positions on this question are critically examined. Topics covered in other chapters include an unusually detailed treatment of theoretical and experimental work on visual space, the two senses of invariance represented by weak and strong reversibility of causal processes, and the representation of hidden variables in quantum mechanics. The final chapter concentrates on different kinds of representations of language, concluding with some empirical results on brain-wave representations of words and sentences. (shrink)

We argue that explanationist views in epistemology continue to face persistent challenges to both their necessity and their sufficiency. This is so despite arguments offered by Kevin McCain in a paper recently published in this journal which attempt to show otherwise. We highlight ways in which McCain’s attempted solutions to problems we had previously raised go awry, while also presenting a novel challenge for all contemporary explanationist views.

The view that phenomenally conscious robots are on the horizon often rests on a certain philosophical view about consciousness, one we call “nomological behaviorism.” The view entails that, as a matter of nomological necessity, if a robot had exactly the same patterns of dispositions to peripheral behavior as a phenomenally conscious being, then the robot would be phenomenally conscious; indeed it would have all and only the states of phenomenal consciousness that the phenomenally conscious being in question has. We experimentally (...) investigate whether the folk think that certain (hypothetical) robots made of silicon and steel would have the same conscious states as certain familiar biological beings with the same patterns of dispositions to peripheral behavior as the robots. Our findings provide evidence that the folk largely reject the view that silicon-based robots would have the sensations that they, the folk, attribute to the biological beings in question. (shrink)

Let’s say that you regard two things as on a par when you don’t prefer one to other and aren’t indifferent between them. What does rationality require of you when choosing between risky options whose outcomes you regard as on a par? According to Prospectism, you are required to choose the option with the best prospects, where an option’s prospects is a probability-distribution over its potential outcomes. In this paper, I argue that Prospectism violates a dominance principle—which I call The (...) Principle of Predominance—because it sometimes requires you to do something that’s no better than the alternatives and might be worse. I argue that this undermines the strongest argument that’s been given in favor of Prospectism. (shrink)

Business and Economic textbooks warn against committing the Sunk Cost Fallacy: you, rationally, shouldn't let unrecoverable costs influence your current decisions. In this paper, I argue that this isn't, in general, correct. Sometimes it's perfectly reasonable to wish to carry on with a project because of the resources you've already sunk into it. The reason? Given that we're social creatures, it's not unreasonable to care about wanting to act in such a way so that a plausible story can be told (...) about you according to which your diachronic behavior doesn't reveal that you've suffered, what I will call, diachronic misfortune. Acting so as to hide that you've suffered diachronic misfortune involves striving to make yourself easily understood while disguising any shortcomings that might damage your reputation as a desirable teammate. And making yourself easily understood to others while hiding your flaws will, sometimes, put pressure on you to honor sunk costs. (shrink)

At least since Aristotle’s famous 'sea-battle' passages in On Interpretation 9, some substantial minority of philosophers has been attracted to the doctrine of the open future--the doctrine that future contingent statements are not true. But, prima facie, such views seem inconsistent with the following intuition: if something has happened, then (looking back) it was the case that it would happen. How can it be that, looking forwards, it isn’t true that there will be a sea battle, while also being true (...) that, looking backwards, it was the case that there would be a sea battle? This tension forms, in large part, what might be called the problem of future contingents. A dominant trend in temporal logic and semantic theorizing about future contingents seeks to validate both intuitions. Theorists in this tradition--including some interpretations of Aristotle, but paradigmatically, Thomason (1970), as well as more recent developments in Belnap, et. al (2001) and MacFarlane (2003, 2014)--have argued that the apparent tension between the intuitions is in fact merely apparent. In short, such theorists seek to maintain both of the following two theses: (i) the open future: Future contingents are not true, and (ii) retro-closure: From the fact that something is true, it follows that it was the case that it would be true. It is well-known that reflection on the problem of future contingents has in many ways been inspired by importantly parallel issues regarding divine foreknowledge and indeterminism. In this paper, we take up this perspective, and ask what accepting both the open future and retro-closure predicts about omniscience. When we theorize about a perfect knower, we are theorizing about what an ideal agent ought to believe. Our contention is that there isn’t an acceptable view of ideally rational belief given the assumptions of the open future and retro-closure, and thus this casts doubt on the conjunction of those assumptions.

The puzzle of petitionary prayer: if we ask for the best thing, God was already going to do it, and if we ask for something that's not the best, God's not going to grant our request. In this paper, we give a new solution to the puzzle.

Coronavirus disease 2019 can lead to respiratory failure. Some patients require extracorporeal membrane oxygenation support. During the current pandemic, health care resources in some cities have been overwhelmed, and doctors have faced complex decisions about resource allocation.

Experts in critical care, end-of-life care, bioethics, and (...) health policy discuss if age should guide rationing decisions. (shrink)

This paper attempts to fill an epistemological gap in our theorizing about love with a sketch of an epistemology of love that unfolds by addressing Whitney Houston’s famous epistemological questions pertaining to how we can know whether another loves us. After arguing for three possible sources of the knowledge of love, it offers initial answers to how the knowledge of the presence or absence of another’s love can be acquired from the relevant possible sources previously established. These initial answers, though, (...) are unsatisfying because they invite more difficult questions that are then addressed, such as those pertaining to the kinds of things that constitute love’s expressions along with how to detect these expressions given the possibility of false positives. Addressing these questions ultimately leads to a sharpened, Aristotle-inspired account of how to acquire the knowledge of the presence or absence of another’s love by inferring it, respectively, from the successful or failed detection of love’s expressions.

What is the best question to ask an omniscient being? The question is intriguing; is it also paradoxical? We discuss several versions of what Ned Markosian calls the paradox of the question and suggest solutions to each of those puzzles. We then offer some practical advice about what do if you ever have the opportunity to query an omniscient being.

In this paper, I introduce a problem to the philosophy of religion – the problem of divine moral standing – and explain how this problem is distinct from (albeit related to) the more familiar problem of evil (with which it is often conflated). In short, the problem is this: in virtue of how God would be (or, on some given conception, is) “involved in” our actions, how is it that God has the moral standing to blame us for performing those (...) very actions? In light of the recent literature on “moral standing”, I consider God’s moral standing to blame on two models of “divine providence”: open theism, and theological determinism. I contend that God may have standing on open theism, and – perhaps surprisingly – may also have standing, even on theological determinism, given the truth of compatibilism. Thus, if you think that God could not justly both determine and blame, then you will have to abandon compatibilism. The topic of this paper thus sheds considerable light on the traditional philosophical debate about the conditions of moral responsibility. (shrink)

This book launches a sustained defense of a radical interpretation of the doctrine of the open future. Patrick Todd argues that all claims about undetermined aspects of the future are simply false.

The Hong and Page ‘diversity trumps ability’ result has been used to argue for the more general claim that a diverse set of agents is epistemically superior to a comparable group of experts. Here we extend Hong and Page’s model to landscapes of different degrees of randomness and demonstrate the sensitivity of the ‘diversity trumps ability’ result. This analysis offers a more nuanced picture of how diversity, ability, and expertise may relate. Although models of this sort can indeed be suggestive (...) for diversity policies, we advise against interpreting such results overly broadly. (shrink)

Four-dimensionalism and eternalism are theories on time, change, and persistence. Christian philosophers and theologians have adopted four-dimensional eternalism for various reasons.

I shall contrast this with presentism and endurantism. Section II will look at some of the purported theological benefits of adopting (...) four-dimensionalism and eternalism. Section III will examine arguments against four-dimensional eternalism from the problem of evil. Section IV will argue that four-dimensional eternalism causes problems for Christian eschatology.

My aim in this chapter is to extend the Realist account of the foundations of linguistics offered by Postal, Katz and others. I first argue against the idea that naive Platonism can capture the necessary requirements on what I call a ‘mixed realist’ view of linguistics, which takes aspects of Platonism, Nominalism and Mentalism into consideration. I then advocate three desiderata for an appropriate ‘mixed realist’ account of linguistic ontology and foundations, namely (1) linguistic creativity and infinity, (2) linguistics as (...) a theory of types (and not tokens) and (3) independence but structural respect between language and the linguistic competence thereof. My own brand of mixed realism, what I call ante rem realism, is defended along the lines of an ante rem or non-eliminative structuralism, the likes of which has been offered for mathematics by Resnik (1997) and Shapiro (1997). In other words, grammars describe a mind-independent (but not necessarily unconnected) linguistic reality in terms of linguistic patterns or structures also known as natural languages. I further amend this picture to allow for the possibility of a naturalistic account of language acquisition and evolution by arguing against a particular view of the type-token distinction. (shrink)

DNA sequencers, Twitter, MRIs, Facebook, particle accelerators, Google Books, radio telescopes, Tumblr: what do these things have in common? According to the evangelists of “data science,” all of these are instruments for observing reality at unprecedentedly large scales and fine granularities. This perspective ignores the social reality of these very different technological systems, ignoring how they are made, how they work, and what they mean in favor of an exclusive focus on what they generate: Big Data. But no data, big (...) or small, can be interpreted without an understanding of the process that generated them. Statistical data science is applicable to systems that have been designed as scientific instruments, but is likely to lead to confusion when applied to systems that have not. In those cases, a historical inquiry is preferable. (shrink)

At least since Aristotle's famous discussion of the sea-battle tomorrow in On Interpretation 9, philosophers have been fascinated by a rich set of interconnecte.

[To readers: Please consider visiting the journal's website to read this work.] In spite of referring to the human tendency to "breath together" or share the same spirit, the word "conspire" has developed a negative connotation in contemporary society, specifically as it pertains to theorizing about conspiracies as a result of the human proclivity to recognize patterns recognition and coalesce common themes amongst those with shared perceptions into something resembling a unified narrative. This proclivity has only become more pronounced with (...) the dawn of the Internet age, and as a result, the tendency to assume the actuality of certain conspiracies and insulate ourselves from viable, competing ideas has led to a series of microenvironments not dissimilar from those that allow for the proliferation of cancerous cells in the human body. In this article, I draw out the analogy between cancer and conspiracy theorizing in order to present readers with a clearer picture of the deleterious effects of the contemporary phenomena such as unbridled political polarization and the effect of sociopolitical news coverage presented by low-correlation outlets, otherwise known as "echo chambers.".

How should you evaluate your choices when you’re unsure what their outcomes will be? One popular answer is to rank your options in terms of their expected utilities. But what should you do when you think that the value of their respective outcomes might be incommensurable? In the face of incommensurable values, it no longer makes sense to speak of ranking your options according to expected utility. Are there any general principles to guide us when facing decisions of this kind? (...) If only! This chapter develops an impossibility result: it holds that there are a handful of independently plausible constraints that no such decision theory can jointly satisfy. The result, while depressing, can be used to helpfully classify extant approaches based on which of the constraints they violate. (shrink)

When you are indifferent between two options, it’s rationally permissible to take either. One way to decide between two such options is to flip a fair coin, taking one option if it lands heads and the other if it lands tails. Is it rationally permissible to employ such a tie-breaking procedure? Intuitively, yes. However, if you are genuinely risk-averse—in particular, if you adhere to risk-weighted expected utility theory (Buchak in Risk and rationality, Oxford University Press, 2013) and have a strictly (...) convex risk-function—the answer will often be no: the REU of deciding by coin-flip will be lower than the REU of choosing one of the options outright (so long as at least one of the options is a nondegenerate gamble). This turns out to be a significant worry for risk-weighted expected utility theory. I argue that it adds real bite to established worries about diachronic consistency afflicting views, like risk-weighted expected utility theory, that violate Independence. And that, while these worries might be surmountable, surmounting them comes at a price. (shrink)
