Until recently, many philosophers took Causal Decision Theory to be more successful than its rival, Evidential Decision Theory. Things have changed, however, with a renewed concern that cases involving an extreme form of decision instability are counterexamples to CDT :392–403, 1984; Egan in Philos Rev 116:93–114, 2007). Most prominent among those cases of extreme decision instability is the Psychopath Button, due to Andy Egan; in that case, CDT recommends a seemingly absurd act that almost certainly results in your death. This (...) renewed attention to decision instability has spurned an array of modifications to and rejections of CDT. I argue, however, that the Psychopath Button and its ilk are no counterexamples to CDT. That is, given the causalist’s commitments in Newcomb Problems, they already have the tools to justify CDT’s verdict in Egan-style cases of extreme decision instability. I first argue that there is no reason to think the Psychopath Button is a counterexample to CDT; in particular, many philosophers have placed too much weight on pre-theoretic intuition in Egan-cases, and apart from pre-theoretic intuition, arguments against CDT in cases of extreme decision instability are flawed. My second claim is that the causalist can provide good reasons for following CDT in cases of extreme decision instability. I present a new case, the Two Button Defense, that highlights precisely why the causalist can reasonably follow CDT in even the Psychopath Button. CDT therefore stands as a viable decision theory, without need for modification, restriction, or rejection. (shrink)

I analyze the “Sportsman’s Code,” arguing that several of its rules presuppose a respect for animals that renders hunting a prima facie wrong. I summarize the main arguments used to justify hunting and consider them in relation to the prima facie case against hunting entailed by the sportsman’s code. Sport hunters, I argue, are in a paradoxical position—the more conscientiously they follow the code, themore strongly their behavior exemplifies a respect for animals that undermines the possibilities of justifying hunting altogether. (...) I consider several responses, including embracing the paradox, renouncing the code, and renouncing hunting. (shrink)

Chimpanzee and hunter-gatherer intergroup aggression differ in important ways, including humans having the ability to form peaceful relationships and alliances among groups. This paper nevertheless evaluates the hypothesis that intergroup aggression evolved according to the same functional principles in the two species—selection favoring a tendency to kill members of neighboring groups when killing could be carried out safely. According to this idea chimpanzees and humans are equally risk-averse when fighting. When self-sacrificial war practices are found in humans, therefore, they result (...) from cultural systems of reward, punishment, and coercion rather than evolved adaptations to greater risk-taking. To test this “chimpanzee model,” we review intergroup fighting in chimpanzees and nomadic hunter-gatherers living with other nomadic hunter-gatherers as neighbors. Whether humans have evolved specific psychological adaptations for war is unknown, but current evidence suggests that the chimpanzee model is an appropriate starting point for analyzing the biological and cultural evolution of warfare.

Rational agents face choices, even when taking seriously the possibility of determinism. Rational agents also follow the advice of Causal Decision Theory (CDT). Although many take these claims to be well-motivated, there is growing pressure to reject one of them, as CDT seems to go badly wrong in some deterministic cases. We argue that deterministic cases do not undermine a counterfactual model of rational deliberation, which is characteristic of CDT. Rather, they force us to distinguish between counterfactuals that are relevant (...) and ones that are irrelevant for the purposes of deliberation. We incorporate this distinction into decision theory to develop ‘Selective Causal Decision Theory’, which delivers the correct recommendations in deterministic cases while respecting the key motivations behind CDT.

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing the truth of (...) certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

Joint actions often require agents to track others’ actions while planning and executing physically incongruent actions of their own. Previous research has indicated that this can lead to visuomotor interference effects when it occurs outside of joint action. How is this avoided or overcome in joint actions? We hypothesized that when joint action partners represent their actions as interrelated components of a plan to bring about a joint action goal, each partner’s movements need not be represented in relation to distinct, (...) incongruent proximal goals. Instead they can be represented in relation to a single proximal goal – especially if the movements are, or appear to be, mechanically linked to a more distal joint action goal. To test this, we implemented a paradigm in which participants produced finger movements that were either congruent or incongruent with those of a virtual partner, and either with or without a joint action goal (the joint flipping of a switch, which turned on two light bulbs). Our findings provide partial support for the hypothesis that visuomotor interference effects can be reduced when two physically incongruent actions are represented as mechanically interdependent contributions to a joint action goal.

Recent research on the evolution of religion has focused on whether religion is an unselected by-product of evolutionary processes or if it is instead an adaptation by natural selection. Adaptive hypotheses for religion include direct fitness benefits from improved health and indirect fitness benefits mediated by costly signals and/or cultural group selection. Herein, I propose that religious denominations achieve indirect fitness gains for members through the use of ecologically arbitrary beliefs, rituals, and moral rules that function as recognition markers of (...) cultural inheritance analogous to kin and species recognition of genetic inheritance in biology. This recognition signal hypotheses could act in concert with either costly signaling or cultural group selection to produce evolutionarily altruistic behaviors within denominations. Using a cultural phylogenetic analysis, I show that a large set of religious behaviors among extant Christian denominations supports the prediction of the recognition signal hypothesis that characters change more frequently near historical schisms. By incorporating demographic data into the model, I show that more-distinctive denominations, as measured through dissimilar characteristics, appear to be protected from intrusion by nonmembers in mixed-denomination households, and that they may be experiencing greater biological growth of their populations even in the present day.

Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation. Determining which tissues are preserved and how biases affect their preservation pathways is important for interpreting fossils in phylogenetic, ecological, and evolutionary frameworks. Although laboratory decay experiments reveal important aspects of fossilization, applying the results directly to the interpretation of exceptionally preserved fossils may overlook the impact of other key processes that (...) remove or preserve morphological information. Investigations of fossils preserving non-biomineralized tissues suggest that certain structures that are decay resistant are rarely preserved, and decay-prone structures can fossilize, albeit rarely. As we review here, decay resistance is an imperfect indicator of fossilization potential, and a suite of biological and geological processes account for the features preserved in exceptional fossils. Organisms decayed experimentally in seawater have been used as direct analogs for soft-bodied fossil taxa, with fossils representing a snapshot of a particular stage of decay. We argue that numerous geological and biological processes account for fossilization and that all of these should be considered when reconstructing extinct organisms. (shrink)

Institutional review boards, tasked with facilitating ethical research, are often pulled in competing directions. In what we call the protection-inclusion dilemma, we acknowledge the tensions IRBs face in aiming to both protect potential research participants from harm and include under-represented populations in research. In this manuscript, we examine the history of protectionism that has dominated research ethics oversight in the United States, as well as two responses to such protectionism: inclusion initiatives and critiques of the term vulnerability. We look at (...) what we know about IRB decision-making in relation to protecting and including “vulnerable” groups in research and examine the lack of regulatory guidance related to this dilemma, which encourages protection over inclusion within IRB practice. Finally, we offer recommendations related to how IRBs might strike a better balance between inclusion and protection in research ethics oversight. (shrink)

Critics charge that Kantian conceptions of human dignity and normative agency, which some suggest underwrite the modern doctrine of human rights, are parochial, unable to account for the dynamism and context-dependence of human rights, aloof from human rights practice, and incapable of distinguishing human rights from the vast array of other political rights constitutional democracies generally recognize as demands of justice. I argue here that whatever force these charges might have against human rights theories inspired by Kant’s work, they do (...) not impugn Kant’s own conception of human rights. By tying human rights to official attitudes toward justice rather than, as familiar approaches do, to concrete conformity with ‘minimum prerequisites’ of justice, Kant’s approach fits core features of human rights practice while providing a dynamic, context-sensitive guideline for auditing the conduct of states and public officials. Just as Kant’s critical writings argue that agents must be able to assume that the natural world of efficient causes is purposive for morality’s ultimate ends, we can profitably understand Kant’s political philosophy as claiming, analogously, that agents must also be able to assume that the juridical world of state action is purposive for justice. Kant’s conception of human rights, I suggest, identifies the conditions under which that assumption is warranted. (shrink)

Ronald Dworkin’s unity of value thesis underlies his influential moral, political, and legal thought. This essay presents an interpretation of the unity thesis designed to isolate its distinctly ethical character, elaborate Dworkin’s fundamental ethical arguments for it, and to utilize this reconstruction to correct misinterpretations that, I argue, underlie recent criticism. This criticism largely depends on construing the unity thesis within a familiar dualistic meta-ethical framework according to which Dworkin’s theory of value is classified as either constructivist or realist in (...) character. Both options, however, misapprehend the epistemological framework within which Dworkin defends value judgments in general, and therefore fail to challenge his use of that framework in defending the unity of value in particular. Correcting this oversight is essential to a proper understanding of Dworkin’s novel account of moral epistemology and of the moral and political program that his unity thesis sponsors. The paper concludes by suggesting how more profitable criticism of the unity of value might proceed. (shrink)

This paper argues that we can better understand Ronald Dworkin's thesis that both individuals and governments must strive to act in accordance with principles that comprise a coherent moral conception, or with what he calls 'integrity', as an instance of Immanuel Kant's fundamental ethical injunction to act in accordance with principles that have the form of law. This Kantian reading of Dworkin highlights the internal, constitutive relation between integrity and a key condition of political legitimacy that Dworkin long stressed: that (...) governments take individual rights _seriously_. Governments take individual rights seriously only by treating humanity as an end in itself, and governments treat humanity as an end in itself only by striving to act in accordance with an integrated system of practical laws. Acting with integrity, taking rights seriously and respecting humanity are thus internally related acts. (shrink)

We introduce a family of rules for adjusting one's credences in response to learning the credences of others. These rules have a number of desirable features. 1. They yield the posterior credences that would result from updating by standard Bayesian conditionalization on one's peers' reported credences if one's likelihood function takes a particular simple form. 2. In the simplest form, they are symmetric among the agents in the group. 3. They map neatly onto the familiar Condorcet voting results. 4. They (...) preserve shared agreement about independence in a wide range of cases. 5. They commute with conditionalization and with multiple peer updates. Importantly, these rules have a surprising property that we call synergy - peer testimony of credences can provide mutually supporting evidence raising an individual's credence higher than any peer's initial prior report. At first, this may seem to be a strike against them. We argue, however, that synergy is actually a desirable feature and the failure of other updating rules to yield synergy is a strike against them.

When the benefits of surgery do not outweigh the harms or where they do not clearly do so, surgical interventions become morally contested. Cutting to the Core examines a number of such surgeries, including infant male circumcision and cutting the genitals of female children, the separation of conjoined twins, surgical sex assignment of intersex children and the surgical re-assignment of transsexuals, limb and face transplantation, cosmetic surgery, and placebo surgery.

Philosophers have spent a great deal of time debating whether intransitive preferences can be rational. I present a risky decision that poses a challenge for the defender of intransitivity. The defender of intransitivity faces a trilemma and must either: (i) reject the rationality of intransitive preferences, (ii) deny State-wise Dominance, or (iii) accept the bizarre verdict that you can be required to pay to relabel the tickets of a fair lottery. If we take the first horn, then we have a (...) synchronic refutation of intransitivity, an improvement on widely criticized diachronic arguments. I sketch possible responses that may rescue intransitivity and argue that each response is possible but generates an explanatory debt. I conclude by showing how the challenge here clarifies the foundations of decision theory without transitivity, conditional on some explanatory debt being payable. (shrink)

The ethical value—and to some scholars, necessity—of providing trial patients with post-trial access (PTA) to an investigational drug has been subject to significant attention in the field of research ethics. Although no consensus has emerged, it seems clear that, in some trial contexts, various factors make PTA particularly appropriate. We outline the atypical aspects of psychedelic clinical trials that support the case for introducing the provision of PTA within research in this field, including the broader legal status of psychedelics, the (...) nature of the researcher-therapist/participant relationship, and the extended time-frame of the full therapeutic process. As is increasingly understood, the efficacy of psychedelic-assisted psychotherapy is driven as much by extrapharmacological elements and the cultural therapeutic container as by the drug itself. As such, we also advocate for a refocusing of attention from post-trial access to a broader concept encompassing other elements of post-trial care. We provide an overview of some of the potential post-trial care provisions that may be appropriate in psychedelic clinical trials. Although the World Medical Association’s Declaration of Helsinki calls on researchers, sponsors, and governments to make provisions for post-trial access, such provision may feel impracticable or out-of-reach within psychedelic trials that are already constrained by a high resource demand and significant bureaucratic burden. We show how conceiving of post-trial provision as an integral site of the research process, and an appropriate destination for research funding, will serve to develop the infrastructure necessary for the post-legalisation psychedelic medicine ecosystem.

No existing normative decision theory adequately handles risk. Expected Utility Theory is overly restrictive in prohibiting a range of reasonable preferences. And theories designed to accommodate such preferences (for example, Buchak's (2013) Risk‐Weighted Expected Utility Theory) violate the Betweenness axiom, which requires that you are indifferent to randomizing over two options between which you are already indifferent. Betweenness has been overlooked by philosophers, and we argue that it is a compelling normative constraint. Furthermore, neither Expected nor Risk‐Weighted Expected Utility Theory (...) allow for stakes‐sensitive risk‐attitudes—they require that risk matters in the same way whether you are gambling for loose change or millions of dollars. We provide a novel normative interpretation of Weighted‐Linear Utility Theory that solves all of these problems. (shrink)

While Plantinga has famously argued that acceptance of neo-Darwinian theory commits one to the rejection of naturalism, Plantinga’s argument is vulnerable to an objection developed by Evan Fales. Not only does Fales’ objection undermine Plantinga’s original argument, it establishes a general challenge which any attempt to revitalize Plantinga’s argument must overcome. After briefly laying out the contours of this challenge, we attempt to meet it by arguing that because a purely naturalistic account of our etiology cannot explain the correlation between (...) our preference for simplicity and simplicity’s ability to serve as a veridical method of theory selection, the scientific realist is committed to the rejection of naturalism.

An actual cause of some token effect is itself a token event that helped to bring about that effect. The notion of an actual cause is different from that of a potential cause – for example a pre-empted backup – which had the capacity to bring about the effect, but which wasn't in fact operative on the occasion in question. Sometimes actual causes are also distinguished from mere background conditions: as when we judge that the struck match was a cause (...) of the fire, while the presence of oxygen was merely part of the relevant background against which the struck match operated. Actual causation is also to be distinguished from type causation: actual causation holds between token events in a particular, concrete scenario; type causation, by contrast, holds between event kinds in scenario kinds.

In their article 'Causes and Explanations: A Structural-Model Approach.

With by far the lowest population density in the United States, myriad challenges attach to healthcare delivery in Alaska. In the “Size, Population, and Accessibility” section, we characterize this geographic context, including how it is exacerbated by lack of infrastructure. In the “Distributing Healthcare” section, we turn to healthcare economics and staffing, showing how these bear on delivery—and are exacerbated by geography. In the “Health Care in Rural Alaska” section, we turn to rural care, exploring in more depth what healthcare (...) delivery looks like outside of Alaska’s major cities. This discussion continues in the “Alaska’s Native Villages” section, which specifically analyzes healthcare in Alaska’s indigenous villages, some of the smallest and most isolated communities in the United States. Though many of the ways we could improve Alaskan health care for Alaskan residents are limited by its unique features, the “Justice and Healthcare Delivery” and “Technology and Telemedicine” sections consider ways in which certain policies and technology—including telemedicine—could mitigate the challenges developed in previous sections.

Wrongdoing is inescapable. We all do wrong and are wronged; and in response we often blame one another. But if blame is a defining feature of our social lives, so is ceasing to blame. We might excuse, justify, or forgive an offender; or simply let the offence go. Each mode of ceasing to blame is a social practice and each has characteristic norms that influence when and how we do it, as well as how it’s received. We argue that how (...) we relinquish blame, and how effective we are, depends on many circumstances only partially within our control. Like any norm-governed practice, one can do it well or poorly, appropriately or inappropriately, successfully or unsuccessfully. To successfully participate in a practice, one’s action must be done for the right reasons and secure uptake. We argue that social and material circumstances can compromise one’s ability to effectively cease to blame in the manner one prefers. But if one can fail, then one can lack access to particular ceasing to blame practices if one is regularly prevented from effectively relinquishing blame. However, uncooperative social and material circumstances do not only arise by chance. Our central argument is that circumstances of oppression can systematically compromise one’s ability and opportunities to effectively perform a variety of ceasing to blame practices. This deprivation is an insidious facet of oppression that is neglected both in theories of oppression and of forgiveness but which has significant implications for how we understand the power and purpose of forgiveness.

This Element provides an accessible introduction to the contemporary philosophy of causation. It introduces the reader to central concepts and distinctions and to key tools drawn upon in the contemporary debate. The aim is to fuel the reader's interest in causation, and to equip them with the resources to contribute to the debate themselves. The discussion is historically informed and outward-looking. 'Historically informed' in that concise accounts of key historical contributions to the understanding of causation set the stage for an (...) examination of the latest research. 'Outward looking' in that illustrations are provided of how the philosophy of causation relates to issues in the sciences, law, and elsewhere. The aim is to show why the study of causation is of critical importance, besides being fascinating in its own right. (shrink)

Consider people’s ordinary concept of belief. This concept seems to pick out a particular psychological state. Indeed, one natural view would be that the concept of belief works much like the concepts one finds in cognitive science – not quite as rigorous or precise, perhaps, but still the same basic type of notion. But now suppose we turn to other concepts that people ordinarily use to understand the mind. Suppose we consider the concept happiness. Or the concept love. How are (...) these concepts to be understood? One obvious hypothesis would be that they are best understood as being more or less like the concept of belief. Maybe these concepts, too, pick out a particular mental state and thereby enable people to predict, explain and understand others’ behavior. We will argue that this hypothesis is mistaken. Instead, we suggest that the different concepts people use to understand the mind are fundamentally different from each other. Some of these concepts do indeed serve simply to pick out a particular mental state, but others allow a role for evaluative judgments. So, for example, our claim will be that when people are wondering whether a given agent is truly ‘happy’ or ‘in love,’ they are not merely trying to figure out whether this agent has a particular sort of mental state. They are also concerned in a central way with evaluating the agent herself. In short, our aim is to point to a striking sort of difference between the different concepts that people use to pick out psychological attitudes. We will be.. (shrink)

This work considers the ways in which, throughout human history, maps have defined our limits as much as charted our exploration. These images act as a kind of ghost vision – a spectral overlay of the world created and accessed as data sets, satellite imagery, and geopolitical mapping, merged in an algorithmically generated 3D mesh. This brings with it a view of the world in which complementary and competing navigational vectors collage and collide. Yet, for all its apparent hyper-modern otherness, (...) its novelty and dexterity is still oriented around and contingent upon the temporal and electromagnetic limits of our biological inheritance.
