One of HLA Hart's main contributions to jurisprudence is his theory of social rules. Hart said, essentially, that a social rule exists if the members of a society act in some way and have a certain attitude. Most legal philosophers think that Hart's account of this attitude is too general, however, and that his theory is overinclusive as a result. In this article, I draw on recent work in the philosophy of action to propose a more precise account of the (...) relevant attitude, and a revised version of Hart's theory. I claim that a social rule exists if the members of a society act in some way and ‘accept’ they ought to act this way, independent of their beliefs about the matter. One of the implications of this idea is that the attitude that underlies a social rule is closely analogous to a presumption or fiction about what ought to be done. -/- . (shrink)

Much of the discussion surrounding the ethics of abortion has centered around the notion of personhood. This is because many philosophers hold that the morality of abortion is contingent on whether the fetus is a person - though, of course, some famous philosophers have rejected this thesis (e.g. Judith Thomson and Don Marquis). In this article, I construct a novel argument for the immorality of abortion based on the notion of impairment. This argument does not assume that the fetus is (...) a person - indeed, I concede (for the sake of argument) that the fetus is not a person - and hence the morality of abortion is not contingent on whether the fetus is a person. I finish by answering a plethora of objections to my argument, concluding that none of them are successful. (shrink)

Legal discourse consists largely of legal claims. These are claims that there is a legal obligation, legal right, or other legal incident. What is the meaning of “legal obligation”, “legal right” and so on in legal claims? The standard view among philosophers of law is that “legal” indicates that, according to law, there is a moral obligation, moral right or other moral incident. Here I set out a new objection to the standard view. The objection is that the standard view (...) is unable to account for the use of legal claims in some common forms of logically complex arguments. (shrink)

It is often assumed that if the fetus is a person, then abortion should be illegal. Thomson1 laid the groundwork to challenge this assumption, and Boonin2 has recently argued that it is false: he argues that abortion should be legal even if the fetus is a person. In this article, I explain both Thomson’s and Boonin’s reason for thinking that abortion should be legal even if the fetus is a person. After this, I show that Thomson’s and Boonin’s argument for (...) legalised abortion fail; they have not given us good reason for thinking abortion should be legal.1 Finally, I argue that—if we play Boonin’s game—abortion should be illegal. When discussing the ethics and politics of abortion, whether the fetus is a person is usually central.3 4.2 However, Thomson1 long ago challenged this view. She argued that abortion is permissible even if the fetus is a person. To do so, she asks us to consider a case in which you are non-consensually taken to a hospital and hooked up to a famous violinist. The violinist, if he is to survive, needs to filter his blood through your body. After 9 months, he will be fine and you can unplug yourself and go on your way. If you unplug yourself prior to this, however, he will die. Is it permissible to unplug yourself? Thomson thinks the answer is ‘yes’. And this, she thinks, shows that abortion is permissible even if the fetus is a person. While the majority of her article focuses on the ethics of abortion, it is clear that she also aims to show that abortion should be legal if the fetus is a person; she would no doubt reject the view that the state is right to coerce you into ….

Tim Maudlin has influentially argued that Humeanism about laws of nature stands in conflict with quantum mechanics. Specifically Humeanism implies the principle Separability: the complete physical state of a world is determined by the intrinsic physical state of each space-time point. Maudlin argues Separability is violated by the entangled states posited by QM. We argue that Maudlin only establishes that a stronger principle, which we call Strong Separability, is in tension with QM. Separability is not in tension with QM. Moreover, (...) while the Humean requires Separability to capture the core tenets of her view, there's no Humean-specific motivation for accepting Strong Separability. We go on to give a Humean account of entangled states which satisfies Separability. The core idea is that certain quantum states depend upon the Humean mosaic in much the same way as the laws do. In fact, we offer a variant of the Best System account on which the systemization procedure that generates the laws also serves to ground these states. We show how this account works by applying it to the example of Bohmian Mechanics. The 3N-dimensional configuration space, the world particle in it and the wave function on it are part of the best system of the Humean mosaic, which consists of N particles moving in 3-dimensional space. We argue that this account is superior to the Humean account of Bohmian Mechanics defended by Loewer and Albert, which takes the 3N-dimensional space, and its inhabitants, as fundamental. (shrink)

In my article "Even if the fetus is not a person, abortion is immoral: The impairment argument" (this journal), I defended what I called “The impairment argument” which purports to show that abortion is immoral. Bruce Blackshaw (2019) has argued that my argument fails on three accounts. In this article, I respond to his criticisms.

In cases in which we must choose between either (i) preventing a woman from remaining unwillingly pregnant or (ii) preventing a fetus from being killed, we should prevent the fetus from being killed. But this suggests that in typical cases abortion is wrong: typical abortions involve preventing a woman from remaining unwillingly pregnant over preventing a fetus from being killed. And so abortion is typically wrong—and this holds whether or not fetuses are persons.

This article is a response to Stephen Law's article ‘The evil-god challenge’. In his article, Law argues that if belief in evil-god is unreasonable, then belief in good-god is unreasonable; that the antecedent is true; and hence so is the consequent. In this article, I show that Law's affirmation of the antecedent is predicated on the problem of good (i.e. the problem of whether an all-evil, all-powerful, and all-knowing God would allow there to be as much good in the world (...) as there is), and argue that the problem of good fails. Thus, the antecedent is unmotivated, which renders the consequent unmotivated. Law's challenge for good-god theists is to show that good-god theism is not rendered unreasonable by the problem of evil in the same way that evil-god theism is rendered unreasonable by the problem of good. Insofar as the problem of good does not render belief in evil-god unreasonable, Law's challenge has been answered: since it is not unreasonable to believe in evil-god (at least for the reasons that Law gives) it is not unreasonable to believe in good-god. Finally, I show that – my criticism aside – the evil-god challenge turns out to be more complicated and controversial than it initially appears, for it relies on the (previously unacknowledged) contentious assumption that sceptical theism is false.

I provide an updated version of The Impairment Argument against abortion and respond to numerous objections that can be (and have been) raised to it.

Abortion restrictions are particularly good for black women—at least in the United States. This claim will likely strike many as outlandish. And numerous commentaries on abortion restrictions have suggested otherwise: many authors have lamented the effects of abortion restrictions on women, and black women in particular—these restrictions are bad for them, these authors say. However, abortion restrictions are clearly good for black women. This is because if someone is prevented from performing a morally wrong action, it’s good for her. For (...) example, it’s good for Sarah if she’s prevented from driving home drunk. However, since abortion is morally wrong, it follows that it’s good for women when they are prevented from getting an abortion. And since black women get abortions at disproportionately high rates, abortion restrictions are good in particular for black women. Indeed, this is an example of a positive effect of intersectionality. (shrink)

Skeptical theism is a popular response to arguments from evil. Many hold that it undermines a key inference often used by such arguments. However, the case for skeptical theism is often kept at an intuitive level: no one has offered an explicit argument for the truth of skeptical theism. In this article, I aim to remedy this situation: I construct an explicit, rigorous argument for the truth of skeptical theism.

Critics of skeptical theism often claim that if it (skeptical theism) is true, then we are in the dark about whether (or for all we know) there is a morally justifying for God to radically deceive us. From here, it is argued that radical skepticism follows: if we are truly in the dark about whether there is a morally justifying reason for God to radically deceive us, then we cannot know anything. In this article, I show that skeptical theism does (...) not entail that we are in the dark about whether (or for all we know) there is a morally justifying reason for God to deceive us. And hence arguments against skeptical theism that make use of this assumption fail. (shrink)

Arguments from evil purport to show that some fact about evil makes it (at least) probable that God does not exist. Skeptical theism is held to undermine many versions of the argument from evil: it is thought to undermine a crucial inference that such arguments often rely on. Skeptical objections to skeptical theism claim that it (skeptical theism) entails an excessive amount of skepticism, and therefore should be rejected. In this article, I show that skeptical objections to skeptical theism have (...) a very limited scope: only those who reject certain (apparently) popular epistemological theories will be threatened by them. (shrink)

The “Embryo Rescue Case” (ERC) refers to a thought experiment that is used to argue against the view that embryos have a right to life (i.e. are persons). I will argue that cognitive science undermines the intuition elicited by the ERC; I will show that whether or not embryos have a right to life, our mental tools will make it very difficult to believe that embryos have said right. This suggests that the intuition elicited by the ERC is not truth (...) indicative. The upshot of this is that we have an undercutting defeater for our intuition that embryos do not have a right to life. (shrink)

Joona Räsänen, in his article ‘Ectogenesis, abortion and a right to the death of the fetus’, has argued for the view that parents have a right to the death of the fetus. In this article, I will explicate the three arguments Räsänen defends, and show that two of them have false or unmotivated premises and hence fail, and that the support he offers for his third argument is inconsistent with other views he expresses in his article. Therefore, I conclude that (...) there is no right to the death of the fetus—or, if there is one, Räsänen has not shown it. (shrink)

Perry Hendricks’ original impairment argument for the immorality of abortion is based on the impairment principle (TIP): if impairing an organism to some degree is immoral, then ceteris paribus, impairing it to a higher degree is also immoral. Since abortion impairs a fetus to a higher degree than fetal alcohol syndrome (FAS) and giving a fetus FAS is immoral, it follows that abortion is immoral. Critics have argued that the ceteris paribus is not met for FAS and abortion, and (...) so we proposed the Modified Impairment Principle (MIP) to avoid these difficulties. Dustin Crummett has responded, arguing that MIP is open to various counterexamples which show it to be false. He also shows that MIP can generate moral dilemmas. Here, we propose a modification to MIP that resolves the issues Crummett raises. Additionally, Alex Gillham has criticized our appropriation of Don Marquis’ ‘future like ours’ reasoning about the wrongness of impairment. We show that his objections have minimal implications for our argument. (shrink)

Trent Dougherty has argued that commonsense epistemology and skeptical theism are incompatible. In this paper, I explicate Dougherty’s argument, and show that (at least) one popular form of skeptical theism is compatible with commonsense epistemology.

Moss (2018) argues that rational agents are best thought of not as having degrees of belief in various propositions but as having beliefs in probabilistic contents, or probabilistic beliefs. Probabilistic contents are sets of probability functions. Probabilistic belief states, in turn, are modeled by sets of probabilistic contents, or sets of sets of probability functions. We argue that this Mossean framework is of considerable interest quite independently of its role in Moss’ account of probabilistic knowledge or her semantics for epistemic (...) modals and probability operators. It is an extremely general model of uncertainty. Indeed, it is at least as general and expressively powerful as every other current imprecise probability framework, including lower probabilities, lower previsions, sets of probabilities, sets of desirable gambles, and choice functions. In addition, we partially answer an important question that Moss leaves open, viz., why should rational agents have consistent probabilistic beliefs? We show that an important subclass of Mossean believers avoid Dutch bookability iff they have consistent probabilistic beliefs. (shrink)

De facto objections to theism purport to show that theism is false, whereas de jure objections to theism claim that, whether or not theism is true, belief in God is irrational. Divine hiddenness – the fact that there are people who non-resistantly lack belief in God – is sometimes used as an argument against theism. In this article I will show that accepting the argument from divine hiddenness carries a high cost: it eliminates all de jure objections to theism. So (...) atheists can either have de jure objections to theism or the objection from divine hiddenness, but they cannot have both. (shrink)

Lougheed argues that a possible solution to the problem of divine hiddenness is that God hides in order to increase the axiological value of the world. In a world where God exists, the goods associated with theism necessarily obtain. But Lougheed also claims that in such a world it’s possible to experience the goods of atheism, even if they don’t actually obtain. This is what makes a world with a hidden God more valuable than a world where God is unhidden, (...) and also more valuable than an atheistic world with no God. We show that Lougheed never considers the comparison between a world where God hides and an atheistic world. We argue that it’s possible for a person to experience theistic goods in a world where God does not exist, a possibility Lougheed never considers. If this is right it undermines his axiological solution to divine hiddenness. We conclude by showing how our discussion of the axiology of theism connects to the existential question of whether God exists; that is, we show that the axiological question is dependent on the existential question.

Perry Hendricks’ impairment argument for the immorality of abortion is based on two premises: first, impairing a fetus with fetal alcohol syndrome is immoral, and second, if impairing an organism to some degree is immoral, then ceteris paribus, impairing it to a higher degree is also immoral. He calls this the impairment principle. Since abortion impairs a fetus to a higher degree than FAS, it follows from these two premises that abortion is immoral. Critics have focussed on the ceteris (...) paribus clause of TIP, which requires that the relevant details surrounding each impairment be sufficiently similar. In this article, we show that the ceteris paribus clause is superfluous, and by replacing it with a more restrictive condition, the impairment argument is considerably strengthened. There are no data in this work. (shrink)

The pelvic exam is used to assess the health of female reproductive organs and so involves digital penetration by a physician. However, it is common practice for medical students to acquire experience in administering pelvic exams by performing them on unconscious patients without prior authorization. In this article, we argue that such unauthorized pelvic exams (UPEs) are sexual assault. Our argument is simple: in any other circumstance, unauthorized digital penetration amounts to sexual assault. Since there are no morally significant differences (...) between UPEs and other instances of digital penetration, UPEs are sexual assault. So, insofar as one is against sexual assault, one should be against UPEs. (shrink)

In this paper, I consider Sterba’s recent criticism of skeptical theism in context of his argument from evil. I show that Sterba’s criticism of skeptical theism shares an undesirable trait with all past criticisms of skeptical theism: it fails. This is largely due to his focus on causal connections and his neglect of logical connections. Because of this, his argument remains vulnerable to skeptical theism.

Skeptical theism is a popular response to arguments from evil. Recently, Matthew A. Benton, John Hawthorne, and Yoaav Isaacs have argued that the theses that ground skeptical theism are either false or limited in scope. In this article, I show that their objections rest on dubious assumptions about the nature of skeptical theism. Along the way, I develop and clarify the ambiguous parts of skeptical theism. The upshot of this is that—once the nature of skeptical theism is made clearer—it is (...) far more difficult to resist. (shrink)

The ethics of abortion considers whether abortion is immoral. Pro-choice philosophers think that it is not immoral, while pro-life philosophers think that it is. The axiology of abortion considers whether world would be better if the pro-choice or pro-life position is right. While much attention has been given to the ethics of abortion, there has been no attention given to the axiology of abortion. In this article, I seek to change that. I consider various arguments for thinking our world would (...) be better if the pro-choice position or the pro-life position is correct, ultimately concluding that it would be better if the pro-choice position is right. This is unfortunate, however, since there is no good reason to think the pro-choice position is correct. (shrink)

This paper is a response to Tyler Wunder’s ‘The modality of theism and probabilistic natural theology: a tension in Alvin Plantinga's philosophy’ (this journal). In his article, Wunder argues that if the proponent of the Evolutionary Argument Against Naturalism (EAAN) holds theism to be non-contingent and frames the argument in terms of objective probability, that the EAAN is either unsound or theism is necessarily false. I argue that a modest revision of the EAAN renders Wunder’s objection irrelevant, and that this (...) revision actually widens the scope of the argument. (shrink)

The subject’s perspective objection (SPO) is an objection against externalist theories of justification, warrant, and knowledge. In this article, I show that externalists can accommodate the SPO while remaining externalist. So, even if the SPO is successful, it does not motivate internalism, and the primary motivation for internalism has been lost. After this, I provide an explanation for why so many people find cases that motivate the SPO convincing.

In this article, I argue that sceptical theists have too narrow a focus: they consider only God’s axiological reasons, ignoring any non-axiological reasons he may have. But this is a mistake: predicting how God will act requires knowing about his reasons in general, and this requires knowing about both God’s axiological and non-axiological reasons. In light of this, I construct and defend a kind of sceptical theism—Deontological Sceptical Theism—that encompasses all of God’s reasons, and briefly illustrate how it renders irrelevant (...) certain charges of excessive sceptical and how it evaporates equiprobability objections. Furthermore, I put forth a simple argument in favor of Deontological Sceptical Theism, which shows that everyone (at least currently) ought to endorse it. (shrink)

What kind of technology is the piano? It was once a distinctly everyday technology. In the bourgeois home of the nineteenth century it became an emblematic figure of gendered social life, its role shifting between visually pleasing piece of furniture, source of light entertainment, and expression of cultured upbringing. It performed this role unobtrusively, acting as a transparent mediator of social relations. To the composer of concert music it was, and sometimes still is, says Samuel Wilson, like the philosopher’s table: (...) “an assumed background on which one writes.” Like other instruments standard to Western art music, the piano was designed to facilitate the production of a consistent and refined timbre. More than most other such instruments, the piano also facilitated a kind of sonic neutrality. With its wide pitch range and smoothing of the percussive attack of its predecessor instruments, the piano presented composers with a technological means of approaching composition from a seemingly objective vantage point. It exemplified, in Heideggerian terms, the instrumentality of the instrument, serving as a mediator between idea and expression that apparently adds no character of its own. -/- This notion of the invisibility, or transparency, of the mediations that musical technologies such as the piano enact is one of my areas of concern here. So too is its inverse: when these mediations become visible or opaque. Transparency has been a topic of significant recent theoretical attention. Stefanos Geroulanos, for example, has detailed how the supposed transparency of intersubjective, epistemological, and social relations was a major point of critique in postwar French thought, where the supposition of transparency was taken to suppress how the world was “complex, layered, structured, filled with heterogeneity” – and, as I will stress here, contingency. The thinkers Geroulanos considers, from Jean-Paul Sartre through to Jean-François Lyotard, can be said to be united in their refusal to invisibilise mediatedness. From a starting point of conceiving of the piano as a technological artifact, and in particular from John Cage’s ‘prepared piano,’ I will explore how a similar concern has appeared in musical contexts, albeit not without the risk of reversion back into a logic of transparency.

An ongoing challenge within all approaches to ethical decision making is reducing the degree of doubt about what action is right, good, or at least better in a given situation. The process of moral discernment within Christian thought is no exception; however, different Christian communities tend to understand moral doubt and moral certainty differently, to pursue different ways of allaying doubt, and to expect—and accept—different degrees of moral certainty. Drawing especially from Aristotelian virtue theory, selected teachings from the Eastern Orthodox (...) tradition on humility, and recent discussions of the ‘grace of self-doubt,’ I sketch an account of virtuous moral doubt as a mean between the extremes of excessive and deficient moral doubt. My hope is doing so will help to make space and provide the framework for an ecumenical understanding of doubt’s proper role in moral discernment. (shrink)

Beliefs are concrete particulars containing ideas of properties and notions of things, which also are concrete. The claim made in a belief report is that the agent has a belief (i) whose content is a specific singular proposition, and (ii) which involves certain of the agent's notions and ideas in a certain way. No words in the report stand for the notions and ideas, so they are unarticulated constituents of the report's content (like the relevant place in "it's raining"). The (...) belief puzzles (Hesperus, Cicero, Pierre) involve reports about two different notions. So the analysis gets the puzzling truth values right. (shrink)

(Wide) pro-theism is the view that the world is better overall if theism is true. (Wide) anti-theism is the view that our world would be better overall if atheism is true. Arguments for pro-theism and anti-theism typically make use of traditional theism (the view that an omni-God exists) and generic atheism (the view that an omni-God doesn’t exist). In my view, when the debate between pro-theists and anti-theists makes use of traditional theism and generic atheism, pro-theism clearly comes out on (...) top. In this paper, I consider whether this result (i.e. pro-theism’s advantage over anti-theism) changes if we bring axiarchism into the mix: I compare axiarchistic theism and axiarchistic atheism. General axiarchism is the view that the world exists because it is good that it exists, and extreme axiarchism is the view that the world exists because it is the best possible world. When we take general axiarchistic theism and general axiarchistic atheism as our worldviews for comparison, I argue that there is no significant change with respect to anti-theism and pro-theism: neither position is able to capture goods that are traditionally associated with the other position, and so pro-theism still wins out. However, if we instead compare extreme axiarchistic atheism with extreme axiarchistic theism there is a significant change: while the case for pro-theism remains the same (because, I argue, it is not able to capture any of the goods of anti-theism), the case for anti-theism is greatly strengthened, because it is able to capture nearly all of the goods of pro-theism (e.g. the good of an afterlife, of cosmic justice, of there being no gratuitous evil). In other words, given extreme axiarchism, atheistic worlds can (and will) house goods that are traditionally associated with theistic worlds (e.g. those listed prior). This means that, given extreme axiarchism, pro-theists can’t appeal to those goods as favoring their position: they obtain whether our world is atheistic or theistic. Thus, they don’t favor pro-theism over anti-theism; the case for anti-theism has been strengthened. (Alternatively, we may say that the case for pro-theism has been weakened.) Ultimately, there is one good that extreme axiarchistic atheism does not enable anti-theism to capture—namely, God’s intrinsic unlimited goodness—and I argue that this shows that there is still a gap between pro-theism and anti-theism; while the gap has been substantially narrowed, it has not been eliminated. Thus, I suggest that the best route forward for anti-theists is to cast doubt on the view that God’s intrinsic goodness is unlimited. (shrink)

This paper is concerned with the aesthetic and discursive gap between music and contemporary art, and the recent attempts to remedy this in the field of New Music through a notion of “New Conceptualism.” It examines why, despite musical sources being central to the emergence of conceptual artistic strategies in the 1950s and ’60s, the worlds of an increasingly transmedial “generic art” and music have remained largely distinct. While it takes New Music’s New Conceptualism as its focus, it argues that (...) the perspective on New Music it takes has wider implications in music and art. It begins by defining what exactly “New Music” refers to, and outlines some of the conditions for the recent rise of conceptualism in New Music. It then takes the work of the composer Johannes Kreidler as a key example of some artistic tendencies and theoretical presuppositions in New Conceptualism. Following this it draws on work in the field of sound studies in order to critically examine the theoretical attempt to connect New Music with contemporary art that is found in the notion of “Music in the Expanded Field.” To conclude it offers some reflections on how a more robust conversation between contemporary art and New Music can begin to be conceived.

Tiddy Smith argues that common consent amongst geographically and historically isolated communities provides strong evidence for animism―the view that there are nature spirits. In this article, I argue that the problem of animistic hiddenness―the lack of widespread belief in nature spirits―is at least as strong evidence against animism that common consent is evidence for it, meaning that the evidence for animism that Smith provides is neutralized.

In this chapter, I consider personal and impersonal anti-theism and personal and impersonal pro-theism. I show that skeptical theism undermines arguments for personal anti-theism and impersonal anti-theism. Next, I show that (at least some) arguments for personal and impersonal pro-theism are not undermined by skeptical theism. This throws a wrench in debates about the axiology of theism: if skeptical theism is true, then it is very difficult to establish certain positions in answer to the axiological question about God.

The evil-god challenge is a challenge for theists to show that belief in God is more reasonable than belief in evil-god. In this article, I show that whether or not evil-god exists, belief in evil-god is unjustified. But this isn’t the case for belief in God: belief in God is probably justified if theism is true. And hence belief in God is (significantly) more reasonable than belief in evil-god, and the evil-god challenge has been answered.

Humeanism – the idea that there are no necessary connections between distinct existences – and Nomic Essentialism – the idea that properties essentially play the nomic roles that they do – are two of the most important and influential positions in the metaphysics of science. Traditionally, it has been thought that these positions were incompatible competitors. We disagree. We argue that there is an attractive version of Humeanism that captures the idea that, for example, mass essentially plays the role that (...) it actually does in the laws of nature. In this paper we consider the arguments that have lead many to conclude that Humeanism cannot be combined with Nomic Essentialism; we identify the weaknesses in these arguments; and we argue in detail that a version of Humeanism based on a variant of the Best System account of laws captures the key intuitions behind nomic essentialism.

In this paper I consider Kendall Walton’s provocative views on the visual arts, including his approaches to understanding both figurative and nonfigurative painting. I introduce his central notion of fictionality, illustrating its advantages in explaining the phenomenon of ‘perceptual twofoldness’. I argue that Walton’s position treats abstract artwork reductively, and I outline two essential components of our aesthetic encounters with the nonfigurative that Walton excludes. I then offer some criticisms of his commitment to photographic realism, emphasising its theoretical inconsistencies with (...) his account of representation. My own proposal is that in our apprehension of non-figurative artworks, our attention is drawn to the underlying structures of both emotive and perceptual experience. In this way, paintings, particularly abstract ones, disclose human cognition in a manner that makes fictionality an inappropriate tool for their analysis. (shrink)

This essay argues that a new subfield of AI governance should be explored that examines the policy-making process and its implications for AI governance. A growing number of researchers have begun working on the question of how to mitigate the catastrophic risks of transformative artificial intelligence, including what policies states should adopt. However, this essay identifies a preceding, meta-level problem of how the space of possible policies is affected by the politics and administrative mechanisms of how those policies are created (...) and implemented. This creates a new set of key considerations for the field of AI governance and should influence the action of future policymakers. This essay examines some of the theories of the policymaking process, how they compare to current work in AI governance, and their implications for the field at large and ends by identifying areas of future research.

This book review of Lieber and Press's “The myth of the nuclear revolution: Power politics in the atomic age" challenges the authors' position that nuclear weapons essentially have the same properties of conventional weapons. We argue that nuclear weapons alter warfare because they can end human civilization, and they pose a shared risk of mutual destruction.

I argue that Plato believes that the soul must be both the principle of motion and the subject of cognition because it moves things specifically by means of its thoughts. I begin by arguing that the soul moves things by means of such acts as examination and deliberation, and that this view is developed in response to Anaxagoras. I then argue that every kind of soul enjoys a kind of cognition, with even plant souls having a form of Aristotelian discrimination (...) (krisis), and that there is therefore no completely unintelligent, evil soul in the cosmos that can explain disorderly motions; as a result, the soul is not the principle of all motion but only motion in the cosmos after it has been ordered by the Demiurge.

It is often argued that the indispensability of continuum models comes from their empirical adequacy despite their decoupling from the microscopic details of the modelled physical system. There is thus a commonly held misconception that temperature varying across a region of space or time can always be accurately represented as a continuous function. We discuss three inter-related cases of temperature modelling — in phase transitions, thermal boundary resistance and slip flows — and show that the continuum view is fallacious on (...) the ground that the microscopic details of a physical system are not necessarily decoupled from continuum models. We show how temperature discontinuities are present in both data (experiments and simulations) and phenomena (theory and models) and how discontinuum models of temperature variation may have greater empirical adequacy and explanatory power. The conclusions of our paper are: a) continuum idealisations are not indispensable to modelling physical phenomena and both continuous and discontinuous representations of phenomena work depending on the context; b) temperature is not necessarily a continuously defined function in our best scientific representations of the world; and c) that its continuity, where applicable, is a contingent matter. We also raise a question as to whether discontinuous representations should be considered truly de-idealised descriptions of physical phenomena. (shrink)

Demonstratives seem to have posed a severe difficulty for Frege’s philosophy of language, to which his doctrine of incommunicable senses was a reaction. In “The Thought,” Frege briefly discusses sentences containing such demonstratives as “today,” “here,” and “yesterday,” and then turns to certain questions that he says are raised by the occurrence of “I” in sentences (T, 24-26). He is led to say that, when one thinks about oneself, one grasps thoughts that others cannot grasp, that cannot be communicated. However, (...) nothing could be more out of the spirit of Frege’s account of sense and thought than an incommunicable, private thought. In the first part of the paper, I explain the problem demonstratives pose for Frege, and explore three ways he might have dealt with it. I argue that none of these ways provides Frege with a solution to his problem consistent with his philosophy of language. The first two are plausible as solutions, but contradict his identification of the sense expressed by a sentence with a thought. The third preserves the identification, but is implausible. In the second part, I suggest that Frege was led to his doctrine of incommunicable senses as a result of some appreciation of the difficulties his account of demonstratives faces, for these come quickly to the surface when we think about “I.” I argue that incommunicable senses won’t help. I end by trying to identify the central problem with Frege’s approach, and sketching an alternative. (shrink)

There is a major debate as to whether there are non-causal mathematical explanations of physical facts that show how the facts under question arise from a degree of mathematical necessity considered stronger than that of contingent causal laws. We focus on Marc Lange’s account of distinctively mathematical explanations to argue that purported mathematical explanations are essentially causal explanations in disguise and are no different from ordinary applications of mathematics. This is because these explanations work not by appealing to what the (...) world must be like as a matter of mathematical necessity but by appealing to various contingent causal facts. (shrink)

To 'consequentialise' is to take a putatively non-consequentialist moral theory and show that it is actually just another form of consequentialism. Some have speculated that every moral theory can be consequentialised. If this were so, then consequentialism would be empty; it would have no substantive content. As I argue here, however, this is not so. Beginning with the core consequentialist commitment to 'maximising the good', I formulate a precise definition of consequentialism and demonstrate that, given this definition, several sorts of (...) moral theory resist consequentialisation. My strategy is to decompose consequentialism into three conditions, which I call 'agent neutrality', 'no moral dilemmas', and 'dominance', and then to exhibit some moral theories which violate each of these.

A Better Ape covers the evolution of morality from the birth of our ape family through the evolution of human species and all the way up to the development of modern societies. In this summary, we highlight several main elements of this account: the co-evolution of morality with intelligence and complex sociality; the role of social institutions and religious morality in the cultural evolution of behaviorally modern humans in prehistory; the increasing complexity of the moral mind through biological evolution in (...) apes, gene-culture co-evolution in various human species, cultural evolution in Homo sapiens, and rational-cultural evolution in recent centuries; and, finally, a cultural evolutionary model of progressive and regressive moral change on which a key factor driving moral progress is social and democratic integration.

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.
