Purpose This systematic review aims to identify factors that influence parents’ decisions regarding pediatric diagnostic and predictive genetic testing (DT/PT). Factors are integrated into a conceptual model of decision-making. Implications for genetic counseling, research, and ethics are derived. Methods PubMed, PsychInfo, WebofScience and references of related reviews were searched for original publications between 2000 and 2023. Extracted factors were categorized into an existing model. Results Of 5843 publications, 56 met inclusion criteria. The included studies differentiate between DT, traditional, and expanded (...) PT and describe factors impacting parental decisions on both to have the child genetically tested and to be informed about additional findings. Factors included: 1. benefits/hopes, 2. worries/concerns, 3. values and beliefs, 4. individual circumstances, and 5. emotional states. Conclusion Our work extends an existing empirical decision model of family decisions about genome sequencing to genetic testing in pediatrics in general, adding the categories “individual circumstances” and “emotional states”. The factors can be further integrated into the Health Belief Model; the importance of emotional states is reflected in dual-process theories, such as Fuzzy Trace Theory. Research is required on emotional states, differences between DT and PT, parents’ decisions about result disclosure, and dyadic variables as decision-making predictors. (shrink)

Powers of Horror is an excellent introduction to an aspect of contemporary French literature which has been allowed to become somewhat neglected in the current emphasis on para-philosophical modes of discourse.".

This paper discusses the inefficacy problem that arises in contexts of “collective harm.‘ These are contexts in which by acting in a certain sort of way, people collectively cause harm, or fail to prevent it, but no individual act of the relevant sort seems to itself make a difference. The inefficacy problem is that if acting in the relevant way won’t make a difference, it’s unclear why it would be wrong. Each individual can argue, “things will be just as bad (...) whether or not I act in this way, so there’s no point in doing otherwise.‘ The goal of this paper is to give an overview of some of the main responses available to the problem and to highlight central issues that arise for each type of response. In the final section, I explain what I take to be the most promising strategy and discuss the form that this strategy should take. (shrink)

There are many cases in which people collectively cause some morally significant outcome (such as a harmful or beneficial outcome) but no individual act seems to make a difference. The problem in such cases is that it seems each person can argue, ‘it makes no difference whether or not I do X, so I have no reason to do it.’ The challenge is to say where this argument goes wrong. My approach begins from the observation that underlying the problem and (...) motivating the typical responses to it is a standard, intuitive assumption. The assumption is that if an act will not make a difference with respect to an outcome, then it cannot play a sig- nificant, non-superfluous role in bringing that outcome about. In other words, helping to bring about an outcome requires making a difference. I argue that the key to solving the problem is to reject this assumption. I develop an account of what it is to help to bring about an outcome, where this does not require making a difference, and I use this explain our reasons for action in the problem cases. This account also yields an error theory that explains why the standard assumption is so tempting, even though it is mistaken. (shrink)

In this paper, I highlight an interesting difference between belief on the one hand, and suspended judgment and credence on the other hand. This difference is the following: credences and suspended judgments are suitable to serve as transitional as well as terminal attitudes in our reasoning, whereas beliefs are only appropriate as terminal attitudes. The notion of a transitional attitude is not an established one in the literature, but I argue that introducing it helps us better understand the different roles (...) suspended judgments and credences can play in our reasoning. Transitional and terminal attitudes have interestingly different descriptive and normative properties. I also compare my account of transitional attitudes to other inquiry-guiding attitudes that have recently been characterized in the literature and explain why they are different. (shrink)

Napolitano (2021) argues that the Minimalist Account of conspiracy theories—i.e., which defines conspiracy theories as explanations, or theories, about conspiracies—should be rejected. Instead, she proposes to define conspiracy theories as a certain kind of belief—i.e., an evidentially self-insulated belief in a conspiracy. Napolitano argues that her account should be favored over the Minimalist Account based on two considerations: ordinary language intuitions and theoretical fruitfulness. I show how Napolitano’s account fails its own purposes with respect to these two considerations and so (...) should not be favored over the Minimalist Account. Furthermore, I propose that the Minimalist Account is the best conception of ‘conspiracy theory’ if we share Napolitano’s goal of advancing the understanding of conspiracy theories. (shrink)

Outlines of Scepticism, by the Greek philosopher Sextus Empiricus, is a work of major importance for the history of Greek philosophy. It is the fullest extant account of ancient scepticism, and it is also one of our most copious sources of information about the other Hellenistic philosophies. Its first part contains an elaborate exposition of the Pyrrhonian variety of scepticism; its second and third parts are critical and destructive, arguing against 'dogmatism' in logic, epistemology, science and ethics - an approach (...) that revolutionized the study of philosophy when Sextus' works were rediscovered and published in the sixteenth century. This volume presents the accurate and readable translation which was first published in 1994, together with a substantial new historical and philosophical introduction by Jonathan Barnes. (shrink)

Until recently, it seemed like no theory about the relationship between rational credence and rational outright belief could reconcile three independently plausible assumptions: that our beliefs should be logically consistent, that our degrees of belief should be probabilistic, and that a rational agent believes something just in case she is sufficiently confident in it. Recently a new formal framework has been proposed that can accommodate these three assumptions, which is known as “the stability theory of belief” or “high probability cores.” (...) In this paper, I examine whether the stability theory of belief can meet two further constraints that have been proposed in the literature: that it is irrational to outright believe lottery propositions, and that it is irrational to hold outright beliefs based on purely statistical evidence. I argue that these two further constraints create a dilemma for a proponent of the stability theory: she must either deny that her theory is meant to give an account of the common epistemic notion of outright belief, or supplement the theory with further constraints on rational belief that render the stability theory explanatorily idle. This result sheds light on the general prospects for a purely formal theory of the relationship between rational credence and belief, i.e. a theory that does not take into account belief content. I argue that it is doubtful that any such theory could properly account for these two constraints, and hence play an important role in characterizing our common epistemic notion of outright belief.

The book provides a commentary on Plato's Republic which encourages the reader to be stimulated to philosophical thinking by Plato's wide-ranging discussions.

We seem less likely to endorse moral expertise than reasoning expertise or aesthetic expertise. This seems puzzling given that moral norms are intuitively taken to be at least more objective than aesthetic norms. One possible diagnosis of the asymmetry is that moral judgments require autonomy of judgement in away that other judgments do not. However, the author points out that aesthetic judgments that have been ‘borrowed’ by aesthetic experts generate the same autonomy worry as moral judgments which are borrowed by (...) moral experts. The author then explores various approaches to accepting the testimony of moral experts and concludes that the asymmetry may best be explained by (1) the conditions for moral expertise being more difficult to satisfy than those of aesthetic expertise and (2) the intuitive greater seriousness of accepting the moral judgments of others, since moral norms are generally viewed as more binding than aesthetic norms.

This paper proposes a novel answer to the question of what attitude agents should adopt when they receive misleading higher-order evidence that avoids the drawbacks of existing views. The answer builds on the independently motivated observation that there is a difference between attitudes that agents form as conclusions of their reasoning, called terminal attitudes, and attitudes that are formed in a transitional manner in the process of reasoning, called transitional attitudes. Terminal and transitional attitudes differ both in their descriptive and (...) in their normative properties. When an agent receives higher-order evidence that they might have reasoned incorrectly to a belief or credence towards p, then their attitude towards p is no longer justified as a terminal attitude towards p, but it can still be justified as a transitional attitude. This view, which I call the unmooring view, allows us to capture the rational impact of misleading higher-order evidence in a way that integrates smoothly with a natural picture of epistemic justification and the dynamics of deliberation.

In this opinionated review, I draw attention to some of the contributions reinforcement learning can make to questions in the philosophy of mind. In particular, I highlight reinforcement learning's foundational emphasis on the role of reward in agent learning, and canvass two ways in which the framework may advance our understanding of perception and motivation.

Taken collectively, consumer food choices have a major impact on animal lives, human lives, and the environment. But it is far from clear how to move from facts about the power of collective consumer demand to conclusions about what one ought to do as an individual consumer. In particular, even if a large-scale shift in demand away from a certain product (e.g., factory-farmed meat) would prevent grave harms or injustices, it typically does not seem that it will make a difference (...) whether one refrains from purchasing that product oneself. Most present-day food companies operate at too large a scale for a single purchase to make a difference to production decisions. If that is true, then it is not clear what point there is in refraining. This is “the problem of collective impact.” This chapter explores a range of proposals for how to solve this problem.

Abstract The article argues that a consideration of the idea, common in ancient ethical theory, that virtue is a skill or craft, reveals that some common construals of it are mistaken. The analogy between virtue and skill is not meant to suggest that virtue is an unreflective habit of practised action. Rather what interests ancient ethical theorists is the intellectual structure of a skill, one demanding grasp of the principles defining the field and an ability to reflect on the justification (...) of particular actions. This is brought out with reference particularly to the discussion of virtue as analogous with skill in Plato's early Socratic dialogues. The demands made of the virtuous agent by philosophers who regard virtue as analogous to skill are akin to the demands made by more recent theories of morality which demand that the moral agent be able to reflect on her practices, extract the principles that these depend on, and produce justification when needed. This point about ancient ethical theories enables us to appreciate their distance from modern versions of ?virtue ethics? ? which stress the importance of the traditions and contexts within which the content of the virtues is learned, and place less importance on the need for intellectual justification. The type of virtue ethics defended by Alasdair Maclntyre provides an instructive example of this contrasting kind of theory. (shrink)

The Modes of Scepticism is one of the most important and influential of all ancient philosophical texts. The texts made an enormous impact on Western thought when they were rediscovered in the 16th century and they have shaped the whole future course of Western philosophy. Despite their importance, the Modes have been little discussed in recent times. This book translates the texts and supplies them with a discursive commentary, concentrating on philosophical issues but also including historical material. The book will (...) be of interest to professional scholars and philosophers but its clear and non-technical style makes it intelligible to beginners and the interested layman. (shrink)

What is it like to be a good person? I examine and reject suggestions that this will involve having thoughts which have virtue or being a good person as part of their content, as well as suggestions that it might be the presence of feelings distinct from the virtuous person’s thoughts. Is there, then, anything after all to the phenomenology of virtue? I suggest that an answer is to be found in looking to Aristotle’s suggestion that virtuous activity is pleasant (...) to the virtuous person. I try to do this, using the work of the contemporary social psychologist Mihalyi Csikszentmihalyi and his work on the ‘flow experience’. Crucial here is the point that I consider accounts of virtue which take it to have the structure of a practical expertise or skill. It is when we are most engaged in skilful complex activity that the activity is experienced as ‘unimpeded’, in Aristotle’s terms, or as ‘flow’. This experience does not, as might at first appear, preclude thoughtful involvement and reflection. Although we can say what in general the phenomenology of virtue is like, each of us only has some more or less dim idea of it from the extent to which we are virtuous—that is, for most of us, not very much.

It is sometimes argued that virtue ethics is incapable of 'telling us what to do'. I explore what this could mean, and come to the conclusion that virtue ethics does enable this, in the only sense in which it is something which we would reasonably want in an ethical theory.

Tanney challenges not only the cognitivist approach that has dominated philosophy and the special sciences for fifty years, but metaphysical-empirical approaches to the mind in general. Rules, Reason, and Self-Knowledge advocates a return to the world-involving, circumstance-dependent, normative practices where the rational mind has its home.

It seems to be a humdrum fact of human agency that we act on intentions or decisions that we have made at an earlier time. At breakfast, you look at the Taco Hut menu online and decide that later today you’ll have one of their avocado burritos for lunch. You’re at your desk and you hear the church bells ring the noon hour. You get up, walk to Taco Hut, and order the burrito as planned. As mundane as this sort (...) of scenario might seem to be, philosophers have raised a problem in understanding it. If you are simply abiding by this morning’s decision, how are you acting autonomously? Your earlier self seems to be calling the shots; if you are just acting accordingly, without thinking through it or in some other way trying to ensure that the past decision conforms to your present standpoint, it is not clear how this amounts to an exercise of your present autonomous agency. It seems, rather, that your earlier self has succeeded in slaving you to her own purposes. She was the one who wanted (intended, judged it to be good, etc.) to have an avocado burrito. In simply following through, your current self seems to be just an automaton performing the commands left behind by your former self. Of course, you might not allow yourself to be shackled by your earlier self. You might refuse to follow anything but your own present judgments: you will only go to Taco Hut if this is what you judge you should do right now, and once at Taco Hut you will only eat the avocado burrito if that is what you want to eat once there. But if this is the way you generally operate, this seems to block your ability to make effective future-directed decisions. The puzzle, then, is one of explaining how the future self can do the bidding of her past self without losing her autonomy. We call this “the Problem of Diachronic Autonomy.” Philosophers raising this problem take it to show that there must be reasons or rational requirements to follow-through with our past decisions. According to these philosophers, we can only make sense of our diachronic autonomy if our past decisions put rational pressure on us to follow through. We argue that there is no Problem of Diachronic Autonomy. There is, in other words, no puzzling situation that needs explaining. Consequently, there is no need coming from this purported puzzle to think that our future-directed decisions generate reasons or rational requirements to follow through. The correct view of our diachronic autonomy is the “naïve” one: the “future self” can do the bidding of the “past self” without giving up its autonomy because, very simply, the past self is the same agent as the future self. I am acting autonomously when I get the avocado burrito, because I was the one who decided to get the burrito. I am acting on my own freely-formed decision. (shrink)

There are many sorts of day-to-day choices that are such that, if enough people were to choose one way rather than another, serious harm could be avoided or reduced, and yet it does not seem that any one such choice will itself make a difference. Consider, for example, how our collective consumer choices have various serious environmental and social consequences, and yet for many products, it is doubtful that one purchase more or less will itself make a difference to these (...) outcomes. How are we to understand what each of us ought to do in these sorts of contexts? This paper further advances and illuminates a thesis that I have argued for elsewhere: that a purely ‘non-instrumental’ approach to this question is not satisfactory. A necessary and central part of understanding how to think about an individual choice in these contexts is showing that it does matter for instrumental reasons - for reasons having to do with its ability to have an influence on the outcome. Once a core instrumental solution is found, other moral considerations can build on top. I argue for this by way of an examination of a new non-instrumental approach advanced by Wieland and van Oeveren: a participation-based approach. I also identify what I think is the main source of resistance to my thesis: a mistaken conflation of two different problems. (shrink)

The emerging field of synthetic biology aims to engineer novel biological entities. The envisioned future bio-based economy builds largely on “cell factories”: organisms that have been metabolically engineered to sustainably produce substances for human ends. In this paper, we argue that synthetic biology’s goal of creating efficient production vessels for industrial applications implies a set of ontological assumptions according to which living organisms are machines. Traditionally, a machine is understood as a technological, isolated and controllable production unit consisting of parts. (...) But modified organisms, or hybrids, require us to think beyond the machine paradigm and its associated dichotomies between artificial and natural, organisms and artefacts. We ask: How may we conceptualise hybrids beyond limiting ontological categories? Our main claim is that the hybrids created by synthetic biology should be considered not as machines but as metabolic systems. We shall show how the philosophical account of metabolism can inform an ontology of hybrids that moves beyond what we call the “machine ontology”, considering that metabolism enables thinking beyond the dominant dichotomies and allows us to understand and design lifeforms in a bio-based economy. Thus, the aim of this paper is twofold: first, to develop the philosophical ontology of hybrids, and second, to move synthetic biology beyond the problematically limiting view of hybrids. (shrink)

_Ethics: The Fundamentals_ explores core ideas and arguments in moral theory by introducing students to different philosophical approaches to ethics, including virtue ethics, Kantian ethics, divine command theory, and feminist ethics. The first volume in the new Fundamentals of Philosophy series. Presents lively, real-world examples and thoughtful discussion of key moral philosophers and their ideas. Constitutes an excellent resource for readers coming to the subject of ethics for the first time.

Bayesian epistemology provides a popular and powerful framework for modeling rational norms on credences, including how rational agents should respond to evidence. The framework is built on the assumption that ideally rational agents have credences, or degrees of belief, that are representable by numbers that obey the axioms of probability. From there, further constraints are proposed regarding which credence assignments are rationally permissible, and how rational agents’ credences should change upon learning new evidence. While the details are hotly disputed, all (...) flavors of Bayesianism purport to give us norms of ideal rationality. This raises the question of how exactly these norms apply to you and me, since perfect compliance with those ideal norms is out of reach for human thinkers. A common response is that Bayesian norms are ideals that human reasoners are supposed to approximate – the closer they come to being ideally rational, the better. To make this claim plausible, we need to make it more precise. In what sense is it better to be closer to ideally rational, and what is an appropriate measure of such closeness? This article sketches some possible answers to these questions. (shrink)

This chapter concerns the nature of our obligations as individuals when it comes to our emissions-producing activities and climate change. The first half of the chapter argues that the popular ‘expected utility’ approach to this question faces a problematic dilemma: either it gives skeptical verdicts, saying that there are no such obligations, or it yields implausibly strong verdicts. The second half of the chapter diagnoses the problem. It is argued that the dilemma arises from a very general feature of the (...) view, and thus is shared by other views as well. The chapter then discusses what an account of our individual obligations needs to look like if it is to avoid the dilemma. Finally, the discussion is extended beyond climate change to other collective impact contexts. (shrink)

When we're inquiring to find out whether p is true, knowing that we'll get better evidence in the future seems like a good reason to suspend judgment about p now. But, as Matt McGrath has recently argued, this natural thought is in deep tension with traditional accounts of justification. On traditional views of justification, which doxastic attitude you are justified in having now depends on your current evidence, not on what you might learn later. McGrath proposes to resolve this tension (...) by distinguishing between different ways of having a neutral attitude. I argue that McGrath's account is unable to account for the full range of cases in which an agnostic attitude is warranted. We can remedy this by pairing his account with my theory of transitional and terminal attitudes, which claims that attitudes are justified in different ways depending on whether they are formed in intermediate stages of deliberation or as conclusions of deliberation. I compare my view with an alternative, more parsimonious one, according to which deliberation itself is a source of new evidence. I argue that this alternative proposal is faced with a dilemma: it either generates a vicious regress, or it fails to capture the relevant cases. (shrink)

Hohwy et al.’s (2008) model of binocular rivalry (BR) is taken as a classic illustration of predictive coding’s explanatory power. I revisit the account and show that it cannot explain the role of reward in BR. I then consider a more recent version of Bayesian model averaging, which recasts the role of reward in (BR) in terms of optimism bias. If we accept this account, however, then we must reconsider our conception of perception. On this latter view, I argue, organisms (...) engage in what amounts to policy-driven, motivated perception.

In the area of moral epistemology, there is an interesting problem facing the person in my area, ancient philosophy, who hopes to write a historical paper which will engage with our current philosophical concerns. Not only are ancient ethical theories very different in structure and concerns from modern ones, but the concerns and emphases of ancient epistemology are very different from those of modern theories of knowledge. Some may think that they are so different that they are useful to our (...) own discussions only by way of contrast. I am more sanguine, but I am quite aware that this essay's contribution to modern debates does not fall within the established modern traditions of discussing moral epistemology. (shrink)

Not many philosophers have dealt seriously with the problems of women's rights and status, and those that have, have unfortunately often been on the wrong side. In fact Plato and Mill are the only great philosophers who can plausibly be called feminists. But there has been surprisingly little serious effort made to analyse their arguments; perhaps because it has seemed like going over ground already won.

Virtue ethics is sometimes taken to be incapable of providing guidance for an individual's actions, as some other ethical theories do. I show how virtue ethics does provide guidance for action, and also meet the objection that, while it may account for what we ought to do, it cannot account for the force of duty and obligation.

Accounts of virtue suffer a conflation problem when they appear unable to preserve intuitive distinctions between types of virtue. In this essay I argue that a number of influential attempts to preserve the distinction between moral and epistemic virtues fail, on the grounds that they characterize virtuous traits in terms of ‘characteristic motivation’. I claim that this does not distinguish virtuous traits at the level of value‐conferring quality, and I propose that the best alternative is to distinguish them at the (...) level of good produced. It follows from this that a consequentialist account is best placed to avoid a conflation of moral and epistemic virtue. (shrink)

Sorensen offers the following definition of a ‘knowledge-lie’: ‘An assertion that p is a knowledge-lie exactly if intended to prevent the addressee from knowing that p is untrue but is not intended to deceive the addressee into believing p.’ According to Sorensen, knowledge-lies are not meant to deceive their addressee, and this fact is supposed to make them less bad than ordinary lies. I will argue that standard cases of knowledge-lies, including almost all the cases Sorensen considers, do in fact (...) involve deception, contrary to what Sorensen claims. And while there are cases of non-deceptive knowledge-lies, such cases are deviant, either because it is only incidental that the knowledge-preventing assertion is a lie, or because it is only incidental that the lie doesn't deceive. Here's an example of a knowledge-lie: Dr Head is considering firing Dr Appendix because of his weak research. But he doesn't want to fire Appendix unless he knows that Appendix's research isn't good, and so he consults Dr Heart. Head knows that if Appendix's research is good, then Heart will tell the truth and say so, whereas if Appendix's work isn't good, then Heart may or may not …. (shrink)

One of the most important developments in the past decades of scholarship on Kant's practical philosophy is a growing interest in his conception of moral character, especially in his conception of virtue. Focusing especially on his later works in moral philosophy, such as the Doctrine of Virtue in his Metaphysics of Morals, commentators have shown that Kant possesses a rich, elaborate account of moral virtue. This has brought partly unexpected aspects of Kantian moral philosophy to new light. We can no (...) longer reduce Kant's moral philosophy to a theory concerned with the moral status of individual actions and the decision procedure leading up to them. Nor can one uphold the view that emotions and sentiments play no... (shrink)
