There are two distinct views on how to formulate an objective consequentialist account of the deontic status of actions, actualism and possibilism. On an actualist account, what matters to the deontic status of actions is only the value of the outcome an action would have, if performed. By contrast, a possibilist account also takes into account the value of the outcomes that an action could have. These two views come apart in their deontic verdicts when an agent is imperfect in (...) an avoidable way, viz., when agent brings about less good than she could. In this paper, I offer an argument against actualism that draws on the connection between moral obligation and practical reasons. (shrink)

How can we rationally make peace with our past moral failings, while committing to avoid similar mistakes in the future? Is it because we cannot do anything about the past, while the future is still open? Or is it that regret for our past mistakes is psychologically harmful, and we need to forgive ourselves in order to be able to move on? Or is it because moral mistakes enable our moral growth? I argue that these and other answers do not (...) properly resolve the problem of temporal asymmetry in our attitudes toward moral imperfection, and I defend an alternative response, centered on our personal attachments and our biographical identity.

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)

Traditional rule consequentialism faces a problem sometimes called the ideal world objection—the worry that by looking only at the consequences in worlds where rules are universally adhered to, the theory fails to account for problems that arise because adherence to rules in the real world is inevitably imperfect. In response, recent theorists have defended sophisticated versions of rule consequentialism which are sensitive to the consequences in worlds with less utopian levels of adherence. In this paper, I argue that these attempts (...) underestimate the problem they are designed to avoid—the worry about ideal worlds is only one manifestation of a deeper and more general problem, the distant world objection, which threatens not only the sophisticated revisions of rule consequentialism, but any view which determines what we ought to do by evaluating worlds that differ from ours in more than what is up to us.

It is often thought that traditional recidivism prediction tools used in criminal sentencing, though biased in many ways, can straightforwardly avoid one particularly pernicious type of bias: direct racial discrimination. They can avoid this by excluding race from the list of variables employed to predict recidivism. A similar approach could be taken to the design of newer, machine learning-based (ML) tools for predicting recidivism: information about race could be withheld from the ML tool during its training phase, ensuring that the (...) resulting predictive model does not use race as an explicit predictor. However, if race is correlated with measured recidivism in the training data, the ML tool may ‘learn’ a perfect proxy for race. If such a proxy is found, the exclusion of race would do nothing to weaken the correlation between risk (mis)classifications and race. Is this a problem? We argue that, on some explanations of the wrongness of discrimination, it is. On these explanations, the use of an ML tool that perfectly proxies race would (likely) be more wrong than the use of a traditional tool that imperfectly proxies race. Indeed, on some views, use of a perfect proxy for race is plausibly as wrong as explicit racial profiling. We end by drawing out four implications of our arguments. (shrink)

This article reviews two standard criticisms of creationism/intelligent design (ID): it is unfalsifiable, and it is refuted by the many imperfect adaptations found in nature. Problems with both criticisms are discussed. A conception of testability is described that avoids the defects in Karl Popper’s falsifiability criterion. Although ID comes in multiple forms, which call for different criticisms, it emerges that ID fails to constitute a serious alternative to evolutionary theory.

Amartya Sen argues that for the advancement of justice identification of ‘perfect’ justice is neither necessary nor sufficient. He replaces ‘perfect’ justice with comparative justice. Comparative justice limits itself to comparing social states with respect to degrees of justice. Sen’s central thesis is that identifying ‘perfect’ justice and comparing imperfect social states are ‘analytically disjoined’. This essay refutes Sen’s thesis by demonstrating that to be able to make adequate comparisons we need to identify and integrate criteria of comparison. This is (...) precisely the aim of a theory of justice (such as John Rawls’s theory): identifying, integrating and ordering relevant principles of justice. The same integrated criteria that determine ‘perfect’ justice are needed to be able to adequately compare imperfect social states. Sen’s alternative approach, which is based on social choice theory, is incapable of avoiding contrary, indeterminate or incoherent directives where plural principles of justice conflict. (shrink)

The paper offers five desiderata on a realist normative theory of politics: that it should avoid moralism, deontologism, transcendentalism, utopianism, and vanguardism. These desiderata argue for a theory that begins from values rooted in a people’s experience; that avoids prescribing a collective deontological constraint; that makes the comparison of imperfect regimes possible; that takes feasibility and sustainability into account; and that makes room for the claims of democracy. The paper argues, in the course of exploring the desiderata, that a neo-republican (...) philosophy of government does pretty well in satisfying them. (shrink)

How should governments balance saving people from very large individual disease burdens (such as an early death) against saving them from middling burdens (such as erectile dysfunction) and minor burdens (such as nail fungus)? This chapter considers this question through an analysis of a priority-setting proposal in the Netherlands, on which avoiding a multitude of middling burdens takes priority over saving one person from early death, but no number of very small burdens can take priority over avoiding one death. It (...) argues that there is some, albeit imperfect, evidence of substantial public support for such a policy. Furthermore, it provides a principled rationale for it in terms of respect for the person who faces the largest burden. (shrink)

Philosophy of religion, approached from a comparative perspective, can be a valuable tool for advancing inter-religious dialogue. Unfortunately, “comparative religion” today is usually characterised by two extreme positions: 1) Comparing religions in order to come to the conclusion that one's own religion is superior 2) Arguing for a type of “religious pluralism” that relativises all religious truth claims. -/- The former approach reduces religion to a confrontational form of apologetics, theatrical “debates” and polemics, while the latter reduces religion to a (...) mere acceptance of pragmatically useful perspectivist narratives devoid of absolute reality or truth. -/- Inter-religious dialogue should follow a middle path between these two extremes by engaging with underlying philosophical themes that are common to all religious traditions instead of emphasising the comparison of theological and soteriological arguments that may depend on justifications that are exclusive to a particular religious practice. The philosophical theme explored here is that of dissatisfaction and existential suffering in an imperfect world, a theme found in all “world religions”. Indeed, the diagnosis of this existential predicament and the hope that religious practice may allow one to overcome it appears to be universal, while its causes and the prescribed remedies differ considerably among religious traditions. Nevertheless, inter-religious dialogue beginning from a conviction that all religious practitioners strive for truth and salvation in response to a common existential experience may lead to a more compassionate and productive dialogue between religious communities. This type of inter-religious dialogue avoids accusations of falling into religious syncretism or relativism while encouraging diverse religious communities to address contemporary issues from areas of philosophical common ground. This allows for a more fruitful type of inter-religious dialogue and comparative study of religion that can be pursued while maintaining one's own distinct religious identities and particular religious truths.

This paper examines Nietzsche’s conflicted relation to Epicurus, an important naturalistic predecessor in the ‘art of living’ tradition. I focus in particular on the Epicurean credo “live unnoticed” (lathe biōsas), which advocated an inconspicuous life of quiet philosophical reflection, self-cultivation and friendship, avoiding the public radar and eschewing the larger ambitions and perturbations of political life. Perhaps unsurprisingly, the idea looms largest and is most warmly received in Nietzsche’s middle period writings, where one finds a repeated concern with prudence, withdrawal (...) and concealment, and where the primary emphasis is on private pluralistic experiments in therapeutic self-cultivation among small groups of free spirits. The idea of the Epicurean Garden appeals greatly to Nietzsche at this time as well, and I suggest that Zarathustra’s Blessed Isles are best understood as a friendship community along these lines. However, Nietzsche’s growing impatience with human imperfections and the siren song of great politics eventually lead him away from Epicurus and back to Plato. Beginning with Zarathustra, the paradigm of the modest, hidden helpful philosopher-therapist is replaced by the more ambitious philosopher-legislator who takes upon himself the task of determining the future of humanity. Nonetheless, I argue that we can profit more from the modest, practical insights of Nietzsche’s Epicurean art of living. (full version). (shrink)

Abstract: In Vacco v. Quill, 521 U.S. 793 (1997), the Supreme Court for the first time in American case law explicitly applied the principle of double effect to reject an equal protection claim to physician-assisted suicide. Double effect, traced historically to Thomas Aquinas, proposes that under certain circumstances it is permissible unintentionally to cause foreseen evil effects that would not be permissible to cause intentionally. The court rejected the constitutional claim on the basis of a distinction marked out by the (...) principle, i.e., between directly intending the death of a terminally ill patient as opposed to merely foreseeing that death as a consequence of medical treatment. The Court held that the distinction comports with fundamental legal principles of causation and intent. Id. at 802. -/- Critics allege that the principle itself is intrinsically flawed and that, in any event, its employment in Vacco is without legal precedent. I argue in response to contemporary objections that double effect is a valid principle of ethical reflection (Part II); claims to the contrary notwithstanding, double effect analysis is a pervasive, albeit generally unacknowledged principle employed regularly in American case law (Part III); and drawing on the preceding two sections, Vacco's application of the principle of double effect is appropriate (Part IV). -/- My conclusion is that [o]peration of some form of the principle, by whatever name, is inevitable. In an imperfect world where duties and interests collide, the possibility of choices of action foreseen to have both good and evil consequences cannot be avoided. In rare circumstances, ethics and the law require that a person refrain from acting altogether. More often, however, they provide that a determination of whether an actor may pursue a good effect although knowing it will or may unintentionally cause an harmful effect requires a more complex analysis - a double effect analysis. -/- Keywords: Equal protection, double effect, intention, physician-assisted suicide, Constitutional Law, Bioethics.

Conflict is a ubiquitous feature of community life, and communities based on inquiry are no exception. Sometimes, conflict escalates into crisis. A crisis may help a community by providing opportunities for its members to recognize and ameliorate their shortcomings, but it may also destroy a community or limit its ability to sustain productive projects. In this discussion, I articulate two orientations towards crisis: crisis-philia (loving crises and seeking them out) and crisis-phobia (fearing crises and seeking to avoid them). I argue, (...) drawing heavily from my experience as a participant in the Summer Seminar of the Institute for the Advancement of Philosophy for Children, that neither orientation is satisfactory. Instead of crisis-philia or crisis-phobia, we ought to get into the habit of inquiring, as a community, about whether our current obstacles to accomplishing our work derive from being constrained by too much (imperfect) structure or from too little stability. When we find it is the former, we ought to seek crises; when we find it is the latter, we ought to avoid crises. After making my case, I offer an example of what it looks look like to implement this conclusion in practice. (shrink)

Structural requirements of rationality prohibit various things, like having inconsistent combinations of attitudes, having means-end incoherent combinations of attitudes, and so on. But what is the distinctive feature of structural requirements of rationality? And do we fall under an obligation to be structurally rational? These issues have been at the heart of significant debates over the past fifteen years. Some philosophers have recently argued that we can unify the structural requirements of rationality by analyzing what is constitutive of our attitudes (...) (Lee, 2020; Worsnip, 2018a). It has also been suggested that, in the course of good first-personal deliberation, agents should treat structurally irrational combinations of attitudes as off-limits (Worsnip, 2021). In this paper, I raise a worry for these two theses concerning structural rationality. Roughly, I argue that some imperfect epistemic agents (like us) can be disposed to have structurally irrational combinations of attitudes. Also, when these imperfect agents deliberate, they should not treat structurally irrational combinations of attitudes as off-limits. Given our imperfections, being structurally irrational can very well be the best option we have. More generally, these observations reveal that structural rationality should not always be theorized independently from more “substantive” norms, like responsiveness to reasons or expected value optimization.

There is virtually no philosophical consensus on what, exactly, imperfect duties are. In this paper, I lay out three criteria which I argue any adequate account of imperfect duties should satisfy. Using beneficence as a leading example, I suggest that existing accounts of imperfect duties will have trouble meeting those criteria. I then propose a new approach: thinking of imperfect duties as duties held by groups, rather than individuals. I show, again using the example of beneficence, that this proposal can (...) satisfy the criteria, explaining how something can both have the necessity characteristic of duty, while also allowing agents the latitude which seems to attach to imperfect duties.

Forgiveness is typically regarded as a good thing - even a virtue - but acts of forgiveness can vary widely in value, depending on their context and motivation. Faced with this variation, philosophers have tended to reinforce everyday concepts of forgiveness with strict sets of conditions, creating ideals or paradigms of forgiveness. These are meant to distinguish good or praiseworthy instances of forgiveness from problematic instances and, in particular, to protect the self-respect of would-be forgivers. But paradigmatic forgiveness is problematic (...) for a number of reasons, including its inattention to forgiveness as a gendered trait. We can account for the values and the risks associated with forgiving far better if we treat it as a moral practice and not an ideal. (shrink)

This paper focuses on the Hasidic view, namely, that human flaws do not function as a barrier between a fallen humanity and a perfect deity, since the whole of creation stems from a divine act of self-contraction. Thus, we need not be discouraged by our own shortcomings, nor by those of our loved ones. Rather, seeing our flaws in the face of another should remind us that imperfection is an aspect of the God who created us. Such a positive approach (...) to human fallibility arouses forgiveness, mutual acceptance, and a hope for repair, and, therefore, has much to recommend itself. In the first part of the paper, I argue that the notion of a perfect God derives from the Greeks rather than the Hebrew Bible. A review of classical philosophies and the idea of God’s imperfection is followed by a consideration of several Jewish attempts to resolve the dichotomy between Divine perfection and an imperfect creation. I focus on Lurianic Kabbalah, Hans Jonas, and on the Hasidic concept of "Ayin " or “nothingness” as the very source of redemption. This Hasidic idea, which was further expanded upon by the Baal Shem Tov’s students, appears in a tale recounted by his great-grandson R. Nachman of Bratslav called “The Hanging Lamp.” I focus on the tale, which illustrates the idea that knowledge of human imperfection is itself a means of perfection and redemption. (shrink)

In this talk, I want to present a conception that I have been working on for a number of years (Zwick, 1983, 1995) about the use of systems ideas. I start from the negative and proceed to the positive. The negative assertion is that systems ideas by themselves , unsupplemented by more specific and concrete knowledge (e.g., from the various disciplines), are insufficient for practical application, either for obtaining knowledge about the world or for solving problems. The reason for this (...) is the inherent abstractness of these ideas. The positive assertion is that this metaphysics can be a rich source of insights needed to improve the human condition and a component of a new scientific world view. (shrink)

In this article, I discuss a trivialization worry for Hartry Field’s official formulation of the access problem for mathematical realists, which was pointed out by Øystein Linnebo. I argue that various attempted reformulations of the Benacerraf problem fail to block trivialization, but that access worriers can better defend themselves by sticking closer to Hartry Field’s initial informal characterization of the access problem in terms of general epistemic norms of coincidence avoidance.

The object of this paper is to provide a solution to Nelson Goodman’s Imperfect Community difficulty as it arises for Resemblance Nominalism, the view that properties are classes of resembling particulars. The Imperfect Community difficulty consists in that every two members of a class resembling each other is not sufficient for it to be a class such that there is some property common to all their members, even if ‘x resembles y’ is understood as ‘x and y share some property’. (...) In the paper I explain and criticise several solutions to the difficulty. Then I develop my own solution, which is not subject to the objections I make to the other solutions, and which accords completely with the basic tenets of Resemblance Nominalism. (shrink)

This paper argues that, with certain provisos, predicting one's future actions is incompatible with rationally deliberating about whether to perform those actions. It follows that fully rational omniscient agents are impossible, since an omniscient being could never rationally deliberate about what to do . Consequently, theories that explain practical reasons in terms of the choices of a perfectly rational omniscient agent must fail. The paper considers several ways of defending the possibility of an omniscient agent, and concludes that while some (...) of these may work, they are inconsistent with the aim of explaining practical normativity by appeal to such an agent.

The culturally pervasive tendency to identify aspects of the body as aesthetically imperfect harms individuals and scaffolds injustice related to disability, race, gender, LGBTQ+ identities, and fatness. But abandoning the notion of imperfection may not respect people’s reasonable understandings of their own bodies. I examine the prospects for a practice of aesthetic assessment grounded in a notion of the body’s function. I argue that functional aesthetic assessment, to be respectful, requires understanding the body’s functions as complex, malleable, and determined by (...) the projects and interests of the person whose body it is. Aesthetically relevant functions, on this account, are determined neither by the body’s status as organism nor by cultural assumptions about how bodies should function or be used. (shrink)

Greg Janzen has recently criticised my defence of Frankfurt’s counterexample to the Principle of Alternate Possibilities by arguing that Jones avoids killing Smith in the counterfactual scenario. Janzen’s argument consists in introducing a new thought-experiment which is supposed to be analogous to Frankfurt’s and where the agent is supposed to avoid A-ing. Here I argue that Janzen’s argument fails on two counts, because his new scenario is not analogous to Frankfurt’s and because the agent in his new scenario does not (...) avoid A-ing. (shrink)

I’m to push back on Hill’s (2022) criticism in four ways.

Third: I address Hill’s claim there is no evidence George W. Bush or Tony Blair accused their critics, during the build-up (...) the invasion of Iraq in 2003ACE, as being “conspiracy theorists.” Fourth (and finally): I will gently suggest that Hill has succumbed to a stereotypical view of work in Philosophy on conspiracy theories.

Research ethics committees must sometimes deliberate about objects that do not fit nicely into any existing category. This is currently the case with the “gastruloid,” which is a self-assembling blob of cells that resembles a human embryo. The resemblance makes it tempting to group it with other members of that kind, and thus to ask whether gastruloids really are embryos. But fitting an ambiguous object into an existing category with well-worn pathways in research ethics, like the embryo, is only a (...) temporary fix. The bigger problem is that we no longer know what an embryo is. We haven’t had a non-absurd definition of ‘embryo’ for several decades and without a well-defined comparison class, asking whether gastruloids belong to the morally relevant class of things we call embryos is to ask a question without an answer. What’s the alternative? A better approach needs to avoid what I’ll refer to as “the potentiality trap” and, instead, rely on the emergence of morally salient facts about gastruloids and other synthetic embryos. (shrink)

Animals are an important part of our social, economic and corporate world. Their wellbeing is significantly affected by the ways in which humans treat them. However, animals have long remained (and, indeed, continue to remain) effectively invisible in the business ethics and corporate responsibility discourse. This article argues in favor of the moral necessity of according animal welfare a higher priority in business. In line with most streams in both recent and traditional animal ethics, this article derives the avoidance of (...) unnecessary animal suffering as the moral minimum standard for responsible management in the livestock industry. Based on a broad range of different interpretations of what animal suffering may be necessary, the article discusses three distinct ways in which humans working in the animal industry could meet their moral responsibility to avoid unnecessary suffering, and, with this, increase animal welfare: by ameliorating circumstances for animals, by aiming at a two-pronged transformation, or by transforming into a “zero-suffering” business. Considering animal welfare as a legitimate ethical value in and of itself is a first step towards overcoming the anthropocentric bias in today's sustainability and corporate responsibility debate.

This review article of Shlomi Segall's Health, Luck, and Justice (Princeton University Press, 2010) addresses three issues: first, Segall’s claim that luck egalitarianism, properly construed, does not object to brute luck equality; second, Segall’s claim that brute luck is properly construed as the outcome of actions that it would have been unreasonable to expect the agent to avoid; and third, Segall’s account of healthcare and criticism of rival views. On the first two issues, a more conventional form of luck egalitarianism (...) – that is, one which objects to brute luck even if it creates equality, and which construes brute luck as the inverse of agent responsibility – is defended. On the third issue, strengths and weaknesses in Segall’s criticism of Rawlsian, democratic egalitarian, and all-luck egalitarian approaches to healthcare, and in his own luck egalitarian approach, are identified.

This article offers a reconstruction of an argument against infinite regress formulated by Aristotle in Posterior Analytics I 22. I argue against the traditional interpretation of the chapter, according to which singular terms and summa genera, in virtue of having restrict logical roles, provide limits for predicative chains, preventing them from proceeding ad infinitum. As I intend to show, this traditional reading is at odds with some important aspects of Aristotle’s theory of demonstration. More importantly, it fails to explain how (...) his proof is connected to a defence of the existence of ultimate explanations, a connection that must be the case if I 19-22 is advancing a foundationalist way-out to a sceptical challenge raised in I 3.

We suggest a new neo-Aristotelian account of right action: An action A is right for an agent S in a situation C just in case it is possible for A in C to result from a good practical inference. A practical inference is good if people must have a disposition to make such practical inferences where a society is to flourish. One advantage of this account is that it applies to non-ideal agents. It thus blocks the right-but-not-virtuous objection to virtue (...) ethics. Our account furthermore suggests a new way of thinking about the concept of a fully virtuous agent. Ideal agents, we argue, necessarily have certain unmanifested dispositions, and failure is a real possibility for them. (shrink)

Until quite recently, it has appeared that eleutheric-conjectural libertarianism (ECL) could not avoid some degree of, very broad, interpersonal utility comparisons (IUCs). And this has been objected to by some of its libertarian critics, notably economists and propertarians. Indeed, this aspect does make the theory less compatible with economics than the rest of the theory and it is thereby a significant problem. This is because one of the main problems that ECL is intended to solve is how an abstract theory (...) of liberty can be compatible with the pro-free-market conclusions of many economists. Being more compatible with economics should make ECL theory more comprehensive, comprehensible, and cogent. (shrink)

The paper argues that given the defining features of the God of “perfect being” theology, God would not create any contingently existing things. To do so would introduce a kind of gratuitous metaphysical imperfection in an otherwise metaphysically perfect universe. Given that in fact there are contingent things, it follows that the God of perfect being theism does not exist.

This paper argues for a conception of the natural rights of non-human animals grounded in Kant’s explanation of the foundation of human rights. The rights in question are rights that are in the first instance held against humanity collectively speaking—against our species conceived as an organized body capable of collective action. The argument proceeds by first developing a similar case for the right of every human individual who is in need of aid to get it, and then showing why the (...) situation of animals is similar. I first review some of the reasons why people are resistant to the idea that animals might have rights. I then explain Kant’s conception of natural rights. I challenge the idea that duties of aid and duties of kindness to animals fit the traditional category of “imperfect duties” and argue that they are instead cases of “imperfect right.” I explain how you can hold a right against a group, and why it is legitimate to conceive of humanity as such a group. I then argue that Kant’s account of the foundation of property rights is grounded in a conception of the common possession of the Earth that grounds a right to aid and the rights of animals to be treated in ways that are consistent with their good. Finally, I return to the objections to the idea that animals have rights and offer some responses to them. (shrink)

Formal representations drawn from rational choice theory have been used in a variety of ways to fruitfully model the way in which actual agents are approximately rational. This analysis requires bridging between ideal normative theory, in which the mechanisms, representations, and other such internal parts are in an important sense interchangeable, and descriptive psychological theory, in which understanding the internal workings of the agent is often the main goal of the entire inquiry. In this paper, I raise a problem brought (...) on by this gap: for almost every theory of approximate rationality, there will be an empirically indistinguishable alternative that individuates the parts of the agent in a significantly different way.

Popper's account of refutation is the linchpin of his famous view that the method of science is the method of conjecture and refutation. This thesis critically examines his account of refutation, and in particular the practice he deprecates as avoiding a refutation. I try to explain how he comes to hold the views that he does about these matters; how he seeks to make them plausible; how he has influenced others to accept his mistakes, and how some of the ideas (...) or responses to Popper of such people are thus similarly mistaken. I draw some distinctions necessary to the provision of an adequate account of the so-called practice of avoiding a refutation, and try to rid the debate about this practice of at least one red herring. I analyse one case of 'avoiding' a refutation in detail to show how the rationality of scientific practice eludes both Popper and many of his commentators. Popper's skepticism about contingent knowledge prevents him from providing an acceptable account of contingent refutation, and so his method is really the method of conjecture and conjecture. He cannot do without the concepts of knowledge and refutation, however, if his account of science is to be plausible or persuasive, and so he equivocates between, amongst other things, refutation as disproof and refutation as the weaker notion of discorroboration. I criticise David Stove's account of this matter, in particular to show how he misses this point. An additional advantage Popper would secure from this equivocation is that if refutations were mere discorroborations they would be easier to achieve, and hence more common in science, than is the case. On Popper's weak notion of refutation, it would be possible to refute true theories since corroboration does not entail truth. There are two other related doctrines Popper holds about refutation which, if accepted, make some refutations seem easier to obtain than is the case. I call these doctrines 'Strong Popperian Falsificationism' (SPF) and 'Weak Popperian Falsificationism' (WPF). SPF is the false doctrine that if a prediction from some theory is refuted then that theory is refuted. Popper does not always endorse SPF. In particular, when confronted with a counterexample to it, he retreats to WPF, which is the false doctrine that if a prediction from some theory is refuted then that theory is prima facie refuted. WPF , or even SPF, can seem plausible if one has in mind predictions derived from theories in strong or conclusive tests of those theories, which I suggest Popper characteristically does. v Popper is disposed to describe any such case of predictive failure which does not lead to the refutation of the theory concerned as one in which that refutation has been avoided. To reinforce his portrayal of the refutation, or the attempted refutation, of major scientific theories as the rational core of scientific practice, Popper treats the so-called practice of avoiding a refutation as untypical of science, and much so-called avoidance he dismisses as unscientific or pseudo-scientific. I argue that his notion of avoiding a refutation is incoherent. Popper is further driven to believe that such avoidance is possible, however, because he conflates sentences with propositions and propositions with propositional beliefs. Also, he wishes to avoid being saddled with the relativisim that is a consequence of his weak account of refutation as discorroboration. Popper believes that ad hoc hypotheses are the most important of the unscientific means of avoiding a refutation. I argue that his account of such hypotheses is also incoherent, and that several hypotheses thought to be ad hoc in his sense are not. Such hypotheses appear to be so largely because of Popper's use of rhetoric and partly because these hypotheses are unacceptable for other reasons. I conclude that to know that a hypothesis is ad hoc in Popper's sense does not illuminate scientific practice. Popper has also attempted to explicate ad hocness in terms of some undesirable, or allegedly undesirable, properties of hypotheses or the explanations they would provide. The first such property is circularity, which is undesirable; the second such property is reduction in empirical content, which is not. In the former case I argue that non-circularity is clearly preferable to non-ad hocness as a criterion for a satisfactory explanation or explanans, as the case may be, and in the latter case that Popper is barking up the wrong tree. Some cases of so-called avoidance are obviously not unscientific. The discovery of Neptune from a prediction based on the reasonable belief that there were residual perturbations in the motion of Uranus is an important case in point, and one that is much discussed in the literature. The manifest failure of astronomers to account for Uranus's motion did not lead to the refutation of Newton's law of gravitiation, yet significant scientific progress obviously did result. Retreating to WPF, Popper claims that Newton's law was prima facie refuted. In general, astronomers have never shared this view, and they are correct in not doing so. I argue that the law of gravitation would have been prima facie refuted only if there had been good reason at the time to believe as false what is true, namely, that an unknown trans-Uranian planet was the cause of those Uranian residuals. Knowledge of the trans-Uranian region was then so slight that it was merely a convenient assumption, one which there was little reason to believe was false, that the known influences on Uranus's motion were the only such influences. I conclude that in believing vi or supposing that it was this assumption that was false, rather than the law of gravitation, Leverrier and Adams, the co-predictors of Neptune, were acting rationally and intelligently. Popper's commentators offer a variety of accounts of the alleged practice of avoiding a refutation, and of this case in particular. I analyse a sample of their accounts to show how common is the acceptance of some of Popper's basic mistakes, even amongst those who claim to reject his falsificationism, and to display the effects on their accounts of this acceptance of his mistakes. Many commentators recognize that anomalies are typically dealt with by changes in the boundary conditions or in other of the auxiliary propositions employed. Where many still go wrong, however, is in retaining the presupposition of WPF which encouraged Popper to hold the contradictory view about anomalies in the first place. Thus Imre Lakatos and others, for example, have developed a 'siege mentality' about major scientific theories; they see them as under continual threat of refutation from anomalies, and so come to believe that dogmatism is essential in science if such theories are to survive as they do. I examine various such doomed attempts to reconcile Popper with the history of science. It is a common failure in this literature to conflate or to fail to see the need to distinguish a belief from a supposition, and an epistemic reason from a pragmatic reason. I argue that only if one does draw these distinctions can one give an adequate account of how anomalies are rationally dealt with in science. The other important strand in Popper's thinking about 'avoidance' of refutation which has seriously misled some of his commentators is his unfounded belief in the dangers of ad hoc hypotheses. I examine the accounts that a sample of such commentators provide of the trans-Uranian planet hypotheses of Leverrier and Adams. These commentators imply or assert what Popper only hints at, namely, that there is something fishy about this hypothesis. I provide a further defence of the rationality of entertaining this hypothesis at the time. I conclude with a few remarks about Popper's dilemma in respect of scientific practice and his long standing emphasis on refutations. (shrink)

The Westermarck Effect posits that intimate association during childhood promotes human incest avoidance. In previous work, I articulated and defended a version of the Westermarck Effect by developing a phylogenetic argument that has purchase within primatology but that has had more limited appeal for cultural anthropologists due to their commitment to conventionalist or culture-first accounts of incest avoidance. Here I look to advance the discussion of incest and incest avoidance beyond culture-first accounts in two ways. First, I shall dig deeper (...) into the disciplinary grooves within cultural anthropology that make attractive the view that incest has a naturalness to it that is countered only or primarily by explicit social rules, such as taboos. Second, I further explore the emerging, post-conventionalist view of incest avoidance in a more positive vein by elaborating on the nature of the Westermarckian mechanism and how it relates to such explicit social rules and our innate biological endowments. One general aim here is to overcome the bifurcation between perspectives that are seen as biological and those seen as cultural, preempting or countering the claim that rejecting culture-first accounts entails a form of biological reductionism, a general aim I have pursued in related publications on bioessentialism about kinship.

The Montreal Declaration on Animal Exploitation, which has been endorsed by hundreds of influential academic ethicists, calls for establishing a vegan economy by banning what it refers to as all unnecessary animal suffering, including fishing. It does so by appeal to the moral principle of equal consideration of comparable interests. I argue that this principle is misapplied by discounting morally relevant cognitive capacities of self-conscious and volitional personhood as distinguished from merely sentient non-personhood. I describe it as a kind of (...) anthropomorphizing moralism which I call anthropomoralism, defined as the tendency to project morally relevant characteristics of personhood onto merely sentient non-persons by discounting their existing differences with actual persons. I show that this attitude can lend support to the resurgent attempt to treat fetal pain as equally morally considerable to that of childbearing persons they gestate within. I explain that the only sound way to apply the principle of equal consideration of comparable interests is to compare experiences of actual persons. Therefore, while supporting a vegan economy may be morally praiseworthy, it should not be deemed morally obligatory. (shrink)

We discuss the cable guy paradox, both as an object of interest in its own right and as something which can be used to illuminate certain issues in the theories of rational choice and belief. We argue that a crucial principle—The Avoid Certain Frustration (ACF) principle—which is used in stating the paradox is false, thus resolving the paradox. We also explain how the paradox gives us new insight into issues related to the Reflection principle. Our general thesis is that principles (...) that base your current opinions on your current opinions about your future opinions need not make reference to the particular times in the future at which you believe you will have those opinions, but they do need to make reference to the particular degrees of belief you believe you will have in the future.

In the situation known as the “cable guy paradox” the expected utility principle and the “avoid certain frustration” principle (ACF) seem to give contradictory advice about what one should do. This article tries to resolve the paradox by presenting an example that weakens the grip of ACF: a modified version of the cable guy problem is introduced in which the choice dictated by ACF loses much of its intuitive appeal.

Many philosophers are attracted to a complaints-based theory of the procreation asymmetry, according to which creating a person with a bad life is wrong (all else equal) because that person can complain about your act, whereas declining to create a person who would have a good life is not wrong (all else equal) because that person never exists and so cannot complain about your act. In this paper, I present two problems for such theories: the problem of impairable-life acceptance and (...) an especially acute version of the problem of improvable-life avoidance. I explain how these problems afflict two recent complaints-based theories of the procreation asymmetry, from Joe Horton and Abelard Podgorski. (shrink)

Russell argued that we can’t know what brains are really like behind our perceptions of them, so minds can conceivably reside in brains. Physicalist-leaning Russellians from Feigl to Strawson try to avoid physicalist and dualist issues with this Russellian idea. Strawson also tries to avoid emergentist issues through panpsychism. Yet critics feel that these Russellians don’t really avoid these issues, but just recast them in new forms. For example, dualist issues arguably remain because it’s hard to see how private pains (...) or colors can reside in solid, grainy, publicly observable brains. Emergence issues arguably remain because panpsychism seems equally unclear as emergentism about how minds arise from brains. This paper revises Strawson and Feigl, while building on recent progress in defusing panpsychism’s emergence issues. It tries to intelligibly formulate Russell’s idea so as to avoid the perennial issues in Russellian and non-Russellian theories, without raising new issues of its own. (shrink)

Epistemological contextualists maintain that the truth-conditions of sentences of the form 'S knows that P' vary according to the context in which they're uttered, where this variation is due to the semantics of 'knows'. Among the linguistic data that have been offered in support of contextualism are several everyday cases. We argue that these cases fail to support contextualism and that they instead support epistemological invariantism—the thesis that the truth-conditions of 'S knows that P' do not vary according to the (...) context of their utterance.

This paper discusses the following question: why was the term “dunatos” (“possible”) employed by Aristotle as an alternative label for imperfect syllogisms in his discussion of assertoric syllogistic? My answer ascribes to Aristotle a bottom up perspective, in which he stresses what is necessary in the premise-pairs to attain target conclusions of a given form within a given figure. I argue that “dunatos” is employed by Aristotle to stress that an imperfect syllogism is always one of the possible options to (...) attain a conclusion of a given form within a given figure. I also argue that this picture sheds some light on Aristotle’s clarifications of the final clause in his definition of syllogism. (shrink)

Should involuntarily childless people have the sameopportunities to access parenthood as those who are not involuntarily childless? In the context of assisted reproductive technologies, affirmative answers to this question are often cashed out in terms of positive rights, including rights to third-party reproduction. In this paper, wecritically explore the scope and extent to which any such right would hold up morally. Ultimately, we argue for a departure away from positive parental rights. Instead, we argue that the state has an imperfect (...) duty to benefit involuntarily childless people in relation to their parental aspirations. (shrink)

This article defends a version of the Westermarck Effect, integrating existing clinical, biological, and philosophical dimensions to incest avoidance. By focusing on care-based attachment in primates, my formulation of the effect suggests the power of a phylogenetic argument widely accepted by primatologists but not by cultural anthropologists. Identifying postadoption incest as a phenomenon with underexplored evidential value, the article sketches an explanatory strategy for reconciling the effect with the clinical reality of incest, concluding with an explicit argument against culture-first or (...) conventionalist accounts of incest avoidance prevalent in anthropology.
