Famous examples of conceivability arguments include (i) Descartes’ argument for mind-body dualism, (ii) Kripke's ‘modal argument’ against psychophysical identity theory, (iii) Chalmers’ ‘zombie argument’ against materialism, and (iv) modal versions of the ontological argument for theism. In this paper, we show that for any such conceivability argument, C, there is a corresponding ‘mirror argument’, M. M is deductively valid and has a conclusion that contradicts C's conclusion. Hence, a proponent of C—henceforth, a ‘conceivabilist’—can be warranted in holding that C's premises (...) are conjointly true only if she can find fault with one of M's premises. But M's premises are modelled on a pair of C's premises. The same reasoning that supports the latter supports the former. For this reason, a conceivabilist can repudiate M's premises only on pain of severely undermining C's premises. We conclude on this basis that all conceivability arguments, including each of (i)–(iv), are fallacious. (shrink)

(Longer version - work in progress) Various accounts of distinctively mathematical explanations (DMEs) of complex systems have been proposed recently which bypass the contingent causal laws and appeal primarily to mathematical necessities constraining the system. These necessities are considered to be modally exalted in that they obtain with a greater necessity than the ordinary laws of nature (Lange 2016). This paper focuses on DMEs of the number of equilibrium positions of n-tuple pendulum systems and considers several different DMEs of these (...) systems which bypass causal features. It then argues that there is a tension between the modal strength of these DMEs and their epistemic hooking, and we are forced to choose between (a) a purported DME with greater modal strength and wider applicability but poor epistemic hooking, or (b) a narrowly applicable DME with lesser modal strength but with the right kind of epistemic hooking. It also aims to show why some kind of DMEs may be unappealing for working scientists despite their strong modality, and why some DMEs fail to be modally robust because of making ill-informed assumptions about their target systems. The broader goal is to show why such tensions weaken the case for DMEs for pendulum systems in general. (shrink)

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. (shrink)

I argue that, according to Plato, the body is the sole cause of psychic disorders. This view is expressed at Timaeus 86b in an ambiguous sentence that has been widely misunderstood by translators and commentators. The goal of this article is to offer a new understanding of Plato’s text and view. In the first section, I argue that although the body is the result of the gods’ best efforts, their sub-optimal materials meant that the soul is constantly vulnerable to the (...) body’s influences. In the second section, I argue that every psychic disorder is a disruption of the motions of the inner psychic circles by the body; moreover, I defend my translation of 86b. In the final section, I argue that the goal of education is to restore the circles to their original orbits, and I disarm a possible objection that bad education is also a cause of psychic disorder. (shrink)

This article concerns the place of Plato’s eschatology in his philosophy. I argue that the theory of reincarnation appeals to Plato due to its power to explain how non-human animals came to be. Further, the outlines of this theory are entailed by other commitments, such as that embodiment disrupts psychic functioning, that virtue is always rewarded and vice punished, and that the soul is immortal. I conclude by arguing that Plato develops a view of reincarnation as the chief tool that (...) the gods have to ensure that virtue is victorious over vice throughout the whole cosmos. (shrink)

In this article, I approach some phenomena seen predominantly on social-media sites that are grouped together as cancel culture with guidance from two major themes in Plato’s thought. In the first section, I argue that shame can play a constructive and valuable role in a person’s improvement, just as we see Socrates throughout Plato’s dialogues use shame to help his interlocutors improve. This insight can help us understand the value of shaming people online for, among other things, their morally reprehensible (...) views. In the second section, I argue that it is required for the proper functioning of democratic institutions that some views be excluded from the public sphere, which follows some Platonic ideas from the Laws. In neither case do I argue that this approach is good in an unqualified sense or even ultima facie good. However, I maintain that these important insights from Plato’s dialogues illuminate crucial aspects of how we should think about cancel culture. (shrink)

This paper concerns Plato’s characterization of the body as the soul’s tool. I take perception as an example of the body’s usefulness. I explore the Timaeus’ view that perception provides us with models of orderliness. Then, I argue that perception of confusing sensible objects is necessary for our cognitive development too. Lastly, I consider the instrumentality relationship more generally and its place in Plato’s teleological worldview.

In this article, I make the case for the continued relevance of Plato’s Timaeus. I begin by sketching Allan Bloom’s picture of the natural sciences today in The Closing of the American Mind, according to which the natural sciences are, objectionably, increasingly specialized and have ejected humans qua humans from their purview. I argue that Plato’s Timaeus, despite the falsity of virtually all of its scientific claims, provides a model for how we can pursue scientific questions in a comprehensive way (...) that stresses their connections to other disciplines, including the humanities, and that puts humanity qua humanity back in the picture. I then argue that being led by Plato’s philosophy to return humanity conceptually to the natural world can improve our thinking regarding climate change and other important environmental crises. (shrink)

I argue that Plato thinks that the soul has location, surface, depth, and extension, and that the Timaeus’ composition of the soul out of eight circles is intended literally. A novel contribution is the development of an account of corporeality that denies the entailment that the soul is corporeal. I conclude by examining Aristotle’s objection to the Timaeus’ psychology and then the intellectual history of this reading of Plato.

Katz denies that organisms created in a lab as part of a de-extinction attempt will be authentic members of the extinct species, on the basis that they will lack the original species’ defining biological and evolutionary history. Against Katz, I note that an evolutionary lineage is conferred on an organism through its inheriting genes from forebears already possessed of such a lineage, and that de-extinction amounts to a delayed, human-assisted reproductive process, in which genes are inherited from forebears long dead. (...) My conclusion is that de-extinct organisms can perfectly well have an ancient evolutionary history, contrary to what Katz claims. (shrink)

In this article, I argue that online echo chambers are in some cases and in some respects good. I do not attempt to refute arguments that they are harmful, but I argue that they are sometimes beneficial. In the first section, I argue that it is sometimes good to be insulated from views with which one disagrees. In the second section, I argue that the software-design principles that give rise to online echo chambers have a lot to recommend them. Further, (...) the opposing principle, serendipity, could give rise to serious harm, in light of the conclusion of the first section that sometimes we are better off being insulated from some content online. In the third section, I argue that polarization can be a useful tool for inculcating the appropriate attitudes in a person. (shrink)

Are the methods of synthetic biology capable of recreating authentic living members of an extinct species? An analogy with the restoration of destroyed natural landscapes suggests not. The restored version of a natural landscape will typically lack much of the aesthetic value of the original landscape because of the different historical processes that created it—processes that involved human intentions and actions, rather than natural forces acting over millennia. By the same token, it would appear that synthetically recreated versions of extinct (...) natural organisms will also be less aesthetically valuable than the originals; that they will be, in some strong sense, ‘inauthentic’, because of their peculiar history and mode of origin. I call this the ‘genesis argument’ against de-extinction. In this article I critically evaluate the genesis argument. I highlight an important disanalogy between living organisms and natural landscapes: viz., it is of the essence of the former, but not of the latter, to regularly reproduce and die. The process of iterated natural reproduction that sustains the continued existence of a species through time obviously does not undermine the authenticity of the species. I argue that the authenticity of a species will likewise be left intact by the kind of artificial copying of genes and traits that a de-extinction project entails. I conclude on this basis that the genesis argument is unsound. (shrink)

I argue that Plato thinks that a sunaition is a mere tool used by a soul (or by the cosmic nous) to promote an intended outcome. In the first section, I develop the connection between sunaitia and Plato’s teleology. In the second section, I argue that sunaitia belong to Plato’s theory of the soul as a self-mover: specifically, they are those things that are set in motion by the soul in the service of some goal. I also argue against several (...) popular and long-standing interpretations, namely, that sunaitia correspond to Aristotle’s idea of hypothetical necessity, that sunaitia are the ‘how’ in an explanation (whereas the true cause is the ‘why’), and that Plato’s causal views should be read through Aristotle’s fourfold schema. I conclude the article by surveying the history of sunaitia after Plato’s usage. (shrink)

This paper concerns the three great modal dichotomies: (i) the necessary/contingent dichotomy; (ii) the a priori/empirical dichotomy; and (iii) the analytic/synthetic dichotomy. These can be combined to produce a tri-dichotomy of eight modal categories. The question as to which of the eight categories house statements and which do not is a pivotal battleground in the history of analytic philosophy, with key protagonists including Descartes, Hume, Kant, Kripke, Putnam and Kaplan. All parties to the debate have accepted that some categories are (...) void. This paper defends the contrary view that all eight categories house statements—a position I dub ‘octopropositionalism’. Examples of statements belonging to all eight categories are given. (shrink)

David Lewis describes, then attempts to refute, a simple anti-Humean theory of desire he calls ‘Desire as Belief’. Lewis’ critics generally accept that his argument is sound and focus instead on trying to show that its implications are less severe than appearances suggest. In this paper I argue that Lewis’ argument is unsound. I show that it rests on an essential assumption that can be straightforwardly proven false using ideas and principles to which Lewis is himself committed.

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)

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)

So-called ‘distinctively mathematical explanations’ (DMEs) are said to explain physical phenomena, not in terms of contingent causal laws, but rather in terms of mathematical necessities that constrain the physical system in question. Lange argues that the existence of four or more equilibrium positions of any double pendulum has a DME. Here we refute both Lange’s claim itself and a strengthened and extended version of the claim that would pertain to any n-tuple pendulum system on the ground that such explanations are (...) actually causal explanations in disguise and their associated modal conditionals are not general enough to explain the said features of such dynamical systems. We argue and show that if circumscribing the antecedent for a necessarily true conditional in such explanations involves making a causal analysis of the problem, then the resulting explanation is not distinctively mathematical or non-causal. Our argument generalises to other dynamical systems that may have purported DMEs analogous to the one proposed by Lange, and even to some other counterfactual accounts of non-causal explanation given by Reutlinger and Rice.

The counterfactual account of physical computation is simple and, for the most part, very attractive. However, it is usually thought to trivialize the notion of physical computation insofar as it implies ‘limited pancomputationalism’, this being the doctrine that every deterministic physical system computes some function. Should we bite the bullet and accept limited pancomputationalism, or reject the counterfactual account as untenable? Jack Copeland would have us do neither of the above. He attempts to thread a path between the two horns (...) of the dilemma by buttressing the counterfactual account with extra conditions intended to block certain classes of deterministic physical systems from qualifying as physical computers. His theory is called the ‘algorithm execution account’. Here we show that the algorithm execution account entails limited pancomputationalism, despite Copeland’s argument to the contrary. We suggest, partly on this basis, that the counterfactual account should be accepted as it stands, pancomputationalist warts and all. (shrink)

This is an impressive and important book about perception in Plato’s Timaeus, but most of its readers will probably be researchers who are interested in much broader questions about the dialogue. There is nothing deficient or lacking about this treatment of perception, but this book should be put alongside Thomas Johansen’s Plato’s Natural Philosophy and Sarah Broadie’s Nature and Divinity in the sense that this is, for all intents and purposes, a monograph about the whole Timaeus, even though it is (...) pitched as being focused on perception. There are only a few topics missing, such as the nature of the cosmic receptacle and psychic diseases. Virtually everything else, including the status of Timaeus’ so-called likely story, the generation of the lower gods, and the nature of bone, is discussed at length. (shrink)

Blame is multifarious. It can be passionate or dispassionate. It can be expressed or kept private. We blame both the living and the dead. And we blame ourselves as well as others. What’s more, we blame ourselves, not only for our moral failings, but also for our non-moral failings: for our aesthetic bad taste, gustatory self-indulgence, or poor athletic performance. And we blame ourselves both for things over which we exerted agential control (e.g., our voluntary acts) and for things over (...) which we lacked such control (e.g., our desires, beliefs, and intentions). I argue that, despite this manifest diversity in our blaming practices, it’s possible to provide comprehensive account of blame. Indeed, I propose a set of necessary and sufficient conditions that aims to specify blame’s extension in terms of its constitution as opposed to its function. And I argue that this proposal has a number of advantages beyond accounting for blame in all its disparate forms. For one, it can account for the fact that one’s having had control over whether one was to φ is a necessary condition for one’s being fittingly blamed for having φ-ed. For another, it can account for why, unlike fitting shame, fitting blame is always deserved, which in turn explains why there is something morally problematic about ridding oneself of one’s fitting self-blame (e.g., one’s fitting guilt).

The editors have put together an interesting and important collection of twelve essays that trace the development of explanations of the human body that appeal to machines and other technological artefacts. Although the focus of the book is ancient authors, with the oldest being Homer and Pindar, the last essay reaches into the eighteenth century, at which point there are no longer mere analogies between human bodies and machines but a conception of the human body as something mechanized. The essays (...) are put together in such a way that emphasizes the early-modern conception as the terminus of the ancient mode of inquiry. (shrink)

In what follows I offer some reflections on an ethics of listening, or perhaps more generally a philosophy of listening, that can be discerned in different forms in the experimental music that, since the 1950s, has challenged and radicalised how music is understood. I situate these reflections around three of my own concert experiences as an audience member.

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.

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. (shrink)

Maximalism is the view that an agent is permitted to perform a certain type of action if and only if she is permitted to perform some instance of this type, where φ-ing is an instance of ψ-ing if and only if φ-ing entails ψ-ing but not vice versa. Now, the aim of this paper is not to defend maximalism, but to defend a certain account of our options that when combined with maximalism results in a theory that accommodates the idea (...) that a moral theory ought to be morally harmonious—that is, ought to be such that the agents who satisfy the theory, whoever and however numerous they may be, are guaranteed to produce the morally best world that they have the option of producing. I argue that, for something to count as an option for an agent, it must, in the relevant sense, be under her control. And I argue that the relevant sort of control is the sort that we exercise over our reasons-responsive attitudes by being both receptive and reactive to reasons. I call this sort of control rational control, and I call the view that φ-ing is an option for a subject if and only if she has rational control over whether she φs rationalism. When we combine this view with maximalism, we get rationalist maximalism, which I argue is a promising moral theory. (shrink)

There is, on a given moral view, an agent-centered restriction against performing acts of a certain type if that view prohibits agents from performing an instance of that act-type even to prevent two or more others from each performing a morally comparable instance of that act-type. The fact that commonsense morality includes many such agent-centered restrictions has been seen by several philosophers as a decisive objection against consequentialism. Despite this, I argue that agent-centered restrictions are more plausibly accommodated within a (...) consequentialist framework than within the more standard side-constraint framework. For I argue that when we combine agent-relative consequentialism with a Kantian theory of value, we arrive at a version of consequentialism, which I call 'Kantsequentialism', that has several advantages over the standard side-constraint approach to accommodating constraints. What’s more, I argue that Kantsequentialism doesn’t have any of the disadvantages that critics of consequentializing have presumed that such a theory must have. (shrink)

On what I take to be the standard account of supererogation, an act is supererogatory if and only if it is morally optional and there is more moral reason to perform it than to perform some permissible alternative. And, on this account, an agent has more moral reason to perform one act than to perform another if and only if she morally ought to prefer how things would be if she were to perform the one to how things would be (...) if she were to perform the other. I argue that this account has two serious problems. The first, which I call the latitude problem, is that it has counterintuitive implications in cases where the duty to be exceeded is one that allows for significant latitude in how to comply with it. The second, which I call the transitivity problem, is that it runs afoul of the plausible idea that the one-reason-morally-justifies-acting-against-another relation is transitive. What’s more, I argue that both problems can be overcome by an alternative account, which I call the maximalist account. (shrink)

In this paper, I take it for granted both that there are two types of blameworthiness—accountability blameworthiness and attributability blameworthiness—and that avoidability is necessary only for the former. My task, then, is to explain why avoidability is necessary for accountability blameworthiness but not for attributability blameworthiness. I argue that what explains this is both the fact that these two types of blameworthiness make different sorts of reactive attitudes fitting and that only one of these two types of attitudes requires having (...) been able to refrain from φ-ing in order for them to be fitting. (shrink)

How do reasons combine? How is it that several reasons taken together can have a combined weight which exceeds the weight of any one alone? I propose an answer in mereological terms: reasons combine by composing a further, complex reason of which they are parts. Their combined weight is the weight of their combination. I develop a mereological framework, and use this to investigate some structural views about reasons, the main two being "Atomism" and "Holism". Atomism is the view that (...) atomic reasons are fundamental: all reasons reduce to atomic reasons. Holism is the view that whole reasons are fundamental. I argue for Holism, and against Atomism. I also consider whether reasons might be "context-sensitive". (shrink)

I provide a comprehensive metaphysics of causation based on the idea that fundamentally things are governed by the laws of physics, and that derivatively difference-making can be assessed in terms of what fundamental laws of physics imply for hypothesized events. Highlights include a general philosophical methodology, the fundamental/derivative distinction, and my mature account of causal asymmetry.

As Socrates famously noted, there is no more important question than how we ought to live. The answer to this question depends on how the reasons that we have for living in various different ways combine and compete. To illustrate, suppose that I've just received a substantial raise. What should I do with the extra money? I have most moral reason to donate it to effective charities but most self-interested reason to spend it on luxuries for myself. So, whether I (...) should live my life as I have most moral reason to live it or as I have most self-interested reason to live it depends on how these and other sorts of reasons combine and compete to determine what I have most reason to do, all things considered. This Element seeks to figure out how different sorts of reasons combine and compete to determine how we ought to live. (shrink)

Some right acts have what philosophers call moral worth. A right act has moral worth if and only if its agent deserves credit for having acted rightly in this instance. And I argue that an agent deserves credit for having acted rightly if and only if her act issues from an appropriate set of concerns, where the appropriateness of these concerns is a function what her ultimate moral concerns should be. Two important upshots of the resulting account of moral worth (...) are that (1) an act can have moral worth even if it doesn’t manifest a concern for doing what’s right and that (2) an act can lack moral worth even if it is performed for the right reasons. (shrink)

I assess the thesis that counterfactual asymmetries are explained by an asymmetry of the global entropy at the temporal boundaries of the universe, by developing a method of evaluating counterfactuals that includes, as a background assumption, the low entropy of the early universe. The resulting theory attempts to vindicate the common practice of holding the past mostly fixed under counterfactual supposition while at the same time allowing the counterfactual's antecedent to obtain by a natural physical development. Although the theory has (...) some success in evaluating a wide variety of ordinary counterfactuals, it fails as an explanation of counterfactual asymmetry. (shrink)

IN THIS PAPER, I make a presumptive case for moral rationalism: the view that agents can be morally required to do only what they have decisive reason to do, all things considered. And I argue that this view leads us to reject all traditional versions of act‐consequentialism. I begin by explaining how moral rationalism leads us to reject utilitarianism.

I defend what may loosely be called an eliminativist account of causation by showing how several of the main features of causation, namely asymmetry, transitivity, and necessitation, arise from the combination of fundamental dynamical laws and a special constraint on the macroscopic structure of matter in the past. At the microscopic level, the causal features of necessitation and transitivity are grounded, but not the asymmetry. At the coarse-grained level of the macroscopic physics, the causal asymmetry is grounded, but not the (...) necessitation or transitivity. Thus, at no single level of description does the physics justify the conditions that are taken to be constitutive of causation. Nevertheless, if we mix our reasoning about the microscopic and macroscopic descriptions, the structure provided by the dynamics and special initial conditions can justify the folk concept of causation to a significant extent. I explain why our causal concept works so well even though at bottom it is comprised of a patchwork of principles that don't mesh well. (shrink)

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)

The problem of standard of care in clinical research concerns the level of treatment that investigators must provide to subjects in clinical trials. Commentators often formulate answers to this problem by appealing to two distinct types of obligations: professional obligations and natural duties. In this article, I investigate whether investigators also possess institutional obligations that are directly relevant to the problem of standard of care, that is, those obligations a person has because she occupies a particular institutional role. I examine (...) two types of institutional contexts: (1) public research agencies – agencies or departments of states that fund or conduct clinical research in the public interest; and (2) private-for-profit corporations. I argue that investigators who are employed or have their research sponsored by the former have a distinctive institutional obligation to conduct their research in a way that is consistent with the state's duty of distributive justice to provide its citizens with access to basic health care, and its duty to aid citizens of lower income countries. By contrast, I argue that investigators who are employed or have their research sponsored by private-for-profit corporations do not possess this obligation nor any other institutional obligation that is directly relevant to the ethics of RCTs. My account of the institutional obligations of investigators aims to contribute to the development of a reasonable, distributive justice-based account of standard of care. (shrink)

Governments are increasingly using randomized controlled trials (RCTs) to evaluate policy interventions. RCTs are often understood to provide the highest quality evidence regarding the causal efficacy of an intervention. While randomization plays an essential epistemic role in the context of policy RCTs however, it also plays an important distributive role. By randomly assigning participants to either the intervention or control arm of an RCT, people are subject to different policies and so, often, to different types and levels of benefits. In (...) this paper, I identify one necessary condition as well as a set of sufficient conditions for the permissible use of random assignment by government agencies. I argue first that random assignment is permissible only if it is consistent with governments’ duty to realize morally important outcomes. I argue second that random assignment is permissible in cases where investigators are in a state of genuine equipoise regarding all arms of the experiment and the policy to which people have a claim of justice. Finally, I defend a set of conditions under which random assignment is permissible in cases where one or more arms of a policy RCT are reasonably expected to be either superior or inferior to this policy.

Many high-income countries have skill-selective immigration policies, favoring prospective immigrants who are highly skilled. I investigate whether it is permissible for high-income countries to adopt such policies. Adopting what Joseph Carens calls a " realistic approach " to the ethics of immigration, I argue first that it is in principle permissible for high-income countries to take skill as a consideration in favor of selecting one prospective immigrant rather than another. I argue second that high-income countries must ensure that their skill-selective (...) immigration policies do not contribute to the non-fulfillment of their duty to aid residents of low-and middle-income countries. (shrink)

In this article, I ask whether a principle analogous to the principle of clinical equipoise should govern the design and conduct of RCTs evaluating the effectiveness of policy interventions. I answer this question affirmatively, and introduce and defend the principle of policy equipoise. According to this principle, all arms of a policy RCT must be, at minimum, in a state of equipoise with the best proven policy that is also morally and practically attainable and sustainable. For all arms of a (...) policy RCT, policy experts must either reasonably disagree about whether the trial arms are more effective than this policy, or know that they are. (shrink)

Australia, Canada, and New Zealand currently apply health requirements to prospective immigrants, denying residency to those with health conditions that are likely to impose an “excessive demand” on their publicly funded health and social service programs. In this paper, I investigate the charge that such policies are wrongfully discriminatory against persons with disabilities. I first provide a freedom-based account of the wrongness of discrimination according to which discrimination is wrong when and because it involves disadvantaging people in the exercise of (...) their freedom on the basis of morally arbitrary features of their identity. Discrimination is permissible, I suggest, when it is necessary to advance a valuable exercise of the discriminating agent’s freedom. I then apply this account to the case of social cost health requirements. Against critics of these requirements, I argue that it is sometimes permissible for states to discriminate against prospective immigrants with disabilities. States may do so, I suggest, when such discriminatory treatment is necessary to prevent an increase in rates of mortality and/or morbidity amongst citizens. Alongside critics of social cost health requirements however, I argue that existing policies are likely a form of wrongful discrimination insofar as they are too broad to satisfy this standard. (shrink)

A principal rationale for public policy is to address market failures. Pareto efficiency is therefore a highly common and relatively non-controversial evaluative criterion for many policy analyses and is discussed at length in policy analysis texts. This makes sense, for Pareto improvements involve making at least one person better off without making anyone worse off. Who could object to that? But does efficiency deserve the prominence it enjoys in public policy? Is one policy option better than another, at least in (...) one respect, simply because it is more Pareto efficient? Or, is efficiency valuable for some other reason? In this chapter, I discuss Pareto efficiency as an evaluative criterion and argue that it is a stand-in for a more foundational criterion: wellbeing. I begin with an overview of Pareto efficiency, discuss the various ways in which it is operationalized to evaluate policy options, and argue that it is valuable insofar as more efficient states of affairs promise more wellbeing than less efficient states of affairs. I then raise questions regarding whether the conception of wellbeing presupposed by Pareto efficiency – preference satisfaction – is a defensible conception of wellbeing. I go on to introduce three alternative conceptions of wellbeing which have been proposed and defended by both philosophers and policy scholars, namely, hedonism, objective goods views, and the capability approach, and suggest ways in which each can be operationalized as an evaluative criterion. I close by discussing four ‘theory-free’ approaches to thinking about the impact of policies on the quality of people’s lives. Such approaches reject the idea that there is one single theory of wellbeing that should be used to evaluate policy options, and instead develop ways to evaluate the impact of policies on people’s lives that are not grounded in a specific theory.

Maximalism is the view that if an agent is permitted to perform a certain type of action (say, baking), this is in virtue of the fact that she is permitted to perform some instance of this type (say, baking a pie), where φ-ing is an instance of ψ-ing if and only if φ-ing entails ψ-ing but not vice versa. Now, the point of this paper is not to defend maximalism, but to defend a certain account of our options that when (...) combined with maximalism results in a theory that both avoids the sorts of objections that have typically been levelled against maximalism and accommodates the plausible idea that a moral theory must be collectively successful in the sense that everyone’s satisfying the theory guarantees that our theory-given aims will be best achieved. I argue that, for something to count as an option for an agent, it must, in the relevant sense, be under her control. And I argue that the relevant sort of control is the sort that we exercise over our reasons-responsive attitudes (e.g., our beliefs, desires, and intentions) by being both receptive and reactive to reasons. I call this sort of control rational control, and I call the view that φ-ing is an option for an agent if and only if she has rational control over whether she φs rationalism. When we combine this view with maximalism, we get rationalist maximalism, which I argue is a promising moral theory. (shrink)

I argue that when determining whether an agent ought to perform an act, we should not hold fixed the fact that she’s going to form certain attitudes (and, here, I’m concerned with only reasons-responsive attitudes such as beliefs, desires, and intentions). For, as I argue, agents have, in the relevant sense, just as much control over which attitudes they form as which acts they perform. This is important because what effect an act will have on the world depends not only (...) on which acts the agent will simultaneously and subsequently perform, but also on which attitudes she will simultaneously and subsequently form. And this all leads me to adopt a new type of practical theory, which I call rational possibilism. On this theory, we first evaluate the entire set of things over which the agent exerts control, where this includes the formation of certain attitudes as well as the performance of certain acts. And, then, we evaluate individual acts as being permissible if and only if, and because, there is such a set that is itself permissible and that includes that act as a proper part. Importantly, this theory has two unusual features. First, it is not exclusively act-orientated, for it requires more from us than just the performance of certain voluntary acts. It requires, in addition, that we involuntarily form certain attitudes. Second, it is attitude-dependent in that it holds that which acts we’re required to perform depends on which attitudes we’re required to form. I then show how these two features can help us both to address certain puzzling cases of rational choice and to understand why most typical practical theories (utilitarianism, virtue ethics, rational egoism, Rossian deontology, etc.) are problematic.

The duty to rescue is a highly plausible and powerful ethical principle. It requires agents to assist others in extreme need in cases where doing so does not conflict with some weighty moral aim; requires little personal sacrifice; and is likely to significantly benefit the recipients.1 As a general obligation, it binds all persons simply qua persons, and it is owed to all persons simply qua persons. Clinical investigators working in low-income countries frequently encounter sick or destitute people to whom (...) they might possess a duty to rescue. Investigators may often ask themselves, what can I do, what should I do, to help? Such investigators often help people in the future by carrying out their... (shrink)

Berkeley, Hume, and Russell rejected the traditional analysis of substances in terms of qualities which are supported by an "unknowable substratum." To them the proper alternative seemed obvious. Eliminate the substratum in which qualities are alleged to inhere, leaving a bundle of coexisting qualities--a view that we may call the Bundle Theory or BT. But by rejecting only part of the traditional substratum theory instead of replacing it entirely, Bundle Theories perpetuate certain confusions which are found in the Substratum Doctrine. (...) I examine two major types of BT developed by Russell and by G. F. Stout with the intention of showing that (1) the seemingly innocuous concept of "a quality" employed by these versions cannot be used to state their theories coherently, and (2) the fatal problems that the BT encounters point to a more satisfactory and interesting alternative to both the Substratum Doctrine and the BT. This is a view that I call the Qualified Particulars Theory. In a final section I draw morals from this discussion that apply to the analogous Humean view that a mind is a "bundle of perceptions and sensations.". (shrink)

The performance of one option can entail the performance of another. For instance, baking an apple pie entails baking a pie. Now, suppose that both of these options—baking a pie and baking an apple pie—are permissible. This raises the issue of which, if either, is more fundamental than the other. Is baking a pie permissible because it’s permissible to bake an apple pie? Or is baking an apple pie permissible because it’s permissible to bake a pie? Or are they equally (...) fundamental, as they would be if they were both permissible because, say, they both accord with Kant’s categorical imperative? I defend the view that the permissibility of an option that entails another is more fundamental than the permissibility of the option that it entails. That is, I defend maximalism: the view that if an agent is permitted to perform a certain type of action (say, baking a pie), this is in virtue of the fact that she is permitted to perform some instance of this type (say, baking an apple pie), where φ-ing is an instance of ψ-ing if and only if φ-ing entails ψ-ing but not vice versa. If maximalism is correct, then, as I show, most theories of morality and rationality must be revised. (shrink)

This paper concerns Warren Quinn’s famous “The Puzzle of the Self-Torturer.” I argue that even if we accept his assumption that practical rationality is purely instrumental such that what he ought to do is simply a function of how the relevant options compare to each other in terms of satisfying his actual preferences that doesn’t mean that every explanation as to why he shouldn’t advance to the next level must appeal to the idea that so advancing would be suboptimal in (...) terms of the satisfaction of his actual preferences. Rather, we can admit that his advancing would always be optimal, but argue that advancing isn’t always what he ought to do given that advancing sometimes fails to meet some necessary condition for being what he ought to do. For instance, something can be what he ought to do only if it’s an option for him. What’s more, something can be what he ought to do only if it’s something that he can do without responding inappropriately to his reasons—or, so, I argue. Thus, the solution to the puzzle is, I argue, to realize that, in certain circumstances, advancing is not what the self-torturer ought to do given that he can do so only by responding inappropriately to his reasons.

This book begins with the question 'Who am I?' and immediately sets off in an astonishingly original direction. Why didn't anyone before Harding think of responding to this question like this? It's so obvious, once you see it. Harding presents a new vision of our place in the universe that uses the scientific method of looking to see what is true. It turns out that the truth about ourselves is not only true but also very good, and breathtakingly beautiful. We (...) live in a sacred, many-layered, living universe - or rather it lives in us. Though it was completed in 1950, this book is still ahead of its time. One day it will surely be widely recognised for its greatness: its all-encompassing vision, its originality and freshness, its depth of insight, its wide-ranging knowledge, the clarity and poetry of its language, its humanity. It is a world-view not dependent on local culture or religion, but on universally verifiable facts. It is also a world-view that respects our manifest differences whilst celebrating our underlying unity - the unity not just of oneself with other people but with all of life, indeed with the whole universe. Harding died in 2007 aged 97, leaving behind him an impressive body of work. He was a highly creative person who was passionate about - he was in love with - this living universe and the immortal treasure that abides at its centre - at our centre.
