The Argument from Uncertainty in the abortion debate is the argument that because the moral status of the fetus is uncertain, abortion policies should afford it maximum protection in order to avoid doing very great evil. Three versions of the argument are developed, and each is based upon an unfounded assumption of a burden of proof in the abortion debate. Each is found to make an unwarranted assumption, or to beg the question, and each (...) fails to provide reasonable support for its conclusion. (shrink)

Moral dilemmas can arise from uncertainty, including uncertainty of the real values involved. One interesting example of this is that of experimentation on human embryos and foetuses, If these have a moral stauts similar to that of human persons then there will be server constraitns on what may be done to them. If embryous have a moral status similar to that of other small clusters of cells, then constraints will be motivated largely by consideration (...) for the persons into whom the embryos may develop. If the truth lies somewhere between these two extremes, the embryo having neither the full moral weight of persons, nor a completely negligible moral weight, then different kinds of constraints will be appropriate. On the face of it, in order to know what kinds of experiements, if any, we are morally justified in performing on embryos we have to know what the moral weight of the embryo is. But then an impasse threatens, for it seems implausible that we can settle with certainty the exact moral status of the human embryo. It is the purpose of this paper to show that moral uncertainty need not make rational moral justification impossible. I develop a framework which distinguishes between what is morally right/wrong, and what is morally justified/unjustified, and applies standard decision theoretic tools to the case of moral uncertainties. (This was the first published account of what has subsequently become known as Expected Moral Value Theory. An earlier version of the paper, "A decision theoretic argument against human embryo experimentation", was published in M. Fricke (ed.), Essays in honor of Bob Durrant. (University of Otago Press, 1986) 111-27.). (shrink)

Although in certain contexts judged to be over-rated,1 consistency is generally held to be a virtue in arguments about medical ethics. In everyday life, to be told that you are acting hypocritically, in a manner that is inconsistent with values you profess, is at least embarrassing, and depending on the circumstances can have more serious consequences, not least for politicians. How far complete consistency in thought and action is humanly possible or even desirable is a more doubtful however. In terms (...) of inconsistency over time, certainly, the maxim ‘When the facts change, I change my mind’ can be a reasonable defence: but in order to avoid less defensible forms of inconsistency, changing your mind about one thing may require changing it about others also. To take seriously just such a possibility is the ethical challenge of this month’s feature article: ‘Moral Uncertainty and the Farming of Human-Pig Chimeras’ by Julian Koplin and Dominic Wilkinson.2 In this case, the facts that have or could soon have changed surround the emerging possibility of generating, within human-pig chimeras, human organs for transplantation into patients who need them and of avoiding the need for immunosuppression by generating the organs using stem cells from the patients themselves. The potential benefits of this possible answer to the worldwide shortage of transplantable organs clearly are immense. But, Koplin and Wilkinson point out, there are also serious potential harms. If human-pig chimeras with ‘partly humanised brains’ were to ‘develop morally relevant cognitive capacities’, such as dawning self-awareness, their moral status would make farming and killing them ‘a serious moral wrong’. Yet having said that, the real difficulty is that we cannot be certain, philosophically, ‘precisely what capacities confer what …. (shrink)

Recent advancements in developmental biology enable the creation of embryo-like structures from human stem cells, which we refer to as human embryo-like structures (hELS). These structures provide promising tools to complement—and perhaps ultimately replace—the use of human embryos in clinical and fundamental research. But what if these hELS—when further improved—also have a claim to moral status? What would that imply for their research use? In this paper, we explore these questions in relation to the traditional answer as to (...) why human embryos should be given greater protection than other (non-)human cells: the so-called Argument from Potential (AfP). According to the AfP, human embryos deserve special moral status because they have the unique potential to develop into persons. While some take the development of hELS to challenge the very foundations of the AfP, the ongoing debate suggests that its dismissal would be premature. Since the AfP is a spectrum of views with different moral implications, it does not need to imply that research with human embryos or hELS that (may) have ‘active’ potential should be completely off-limits. However, the problem with determining active potential in hELS is that this depends on development passing through ‘potentiality switches’ about the precise coordinates of which we are still in the dark. As long as this epistemic uncertainty persists, extending embryo research regulations to research with specific types of hELS would amount to a form of regulative precaution that as such would require further justification.

Setting aside some complexities, Koplin and Wilkinson1 argue: 1. Moral status is uncertain if there is a non-zero chance that an entity has, or would develop, full moral status. 2. If its moral status is uncertain, then moral caution is warranted towards that entity. 3. The moral status of both non-chimeric pigs and human-pig chimaeras is uncertain. Therefore, consistency demands that moral caution is warranted towards both non-chimeric pigs and human-pig chimaeras. 4. The commonly (...) held view is that moral caution is warranted towards human-pig chimaeras, but not non-chimeric pigs. Therefore, the commonly held view is inconsistent. This is a valid argument. The authors claim that the inconsistency they expose in conclusion 2 could be resolved in favour of either commonly held view, or by revising both to equivalency. However, it is clear from conclusion 1, and the paper more generally, that the authors are arguing for moral caution to be applied to the treatment of pigs of both types. I will focus on evaluating premises 1 and 2, and the generalisability of the argument in light of this. In doing so, I will attempt to show that the argument has implausible logical implications, and that the moral caution warranted towards human-pig chimaeras of uncertain moral status does not require confidence that they lack full moral status, as the authors claim. According to premise 1, if an entity might currently have moral …. (shrink)

The proliferation of prenatal genetic testing likely to follow from advances in genetic science invites reconsideration of the moral status of abortion. In this article I examine arguments surrounding the moral status of the fetus. I conclude that secular philosophy should ultimately admit that the moral status of the fetus is uncertain, and that this uncertainty itself makes abortion morally problematic. While this does not imply that abortion is always morally wrong or that it should (...) be legally prohibited, it does recommend a presumption in favor of preserving fetal life except in special circumstances. A relevant worry is that the rise of eugenic abortion gives new force to slippery slope arguments that we will be led down a path to a situation where more fetuses are terminated for relatively trivial reasons and that this will promote other bad social consequences. This might justify legislative discouragement of certain genetic interventions. (shrink)

We’re often unsure what morality requires, but we need to act anyway. There is a growing philosophical literature on how to navigate moral uncertainty. But much of it asks how to rationally pursue the goal of acting morally, using decision-theoretic models to address that question. I argue that using these popular approaches leaves some central and pressing questions about moral uncertainty unaddressed. To help us make sense of experiences of moral uncertainty, we should shift (...) away from focusing on what it’s rational to do when facing moral uncertainty, and instead look directly at what it’s moral to do about moral uncertainty—for example, how risk averse we morally ought to be, or which personal sacrifices we’re morally obligated to make in order to reduce our risk of moral wrongdoing. And orthodox, expectation-maximizing, decision-theoretic models aren’t well-suited to this task—in part because they presuppose the answers to some important moral questions. For example, if approaching moral uncertainty in a moral way requires us to “maximize expected moral rightness,” that’s, itself, a contentious claim about the demands of morality—one that requires significant moral argument, and that I ultimately suggest is mistaken. Of course, it’s possible to opt, instead, for a variety of alternative decision-theoretic models. But, in order to choose between proposed decision-theoretic models, and select one that is well-suited to handling these cases, we first would need to settle more foundational, moral questions—about, for example, what we should be willing to give up in order to reduce the risk that we’re acting wrongly. Decision theory may be able to formalize the conclusions of these deliberations, but it is not a substitute for them, and it won’t be able to settle the right answers in advance. For now, when we discuss moral uncertainty, we need to wade directly into moral debate, without the aid of decision theory’s formalism. (shrink)

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

Consciousness and confidence seem intimately related. Accordingly, some researchers use confidence ratings as a measure of, or proxy for, consciousness. Rosenthal discusses the potential connections between the two, and rejects confidence as a valid measure of consciousness. He argues that there are better alternatives to get at conscious experiences such as direct subjective reports of awareness (i.e. subjects’ reports of perceiving something or of the degree of visibility of a stimulus). In this chapter, we offer a different perspective. Confidence ratings (...) in general, and metacognitive measures in particular, may offer important advantages over subjective ratings. The arguments we offer here are supported by empirical, practical and socio-strategic considerations. However, we do not suggest consciousness and confidence are interchangeable. We recognize the limitations of confidence ratings in some experimental designs and for some research questions. Nevertheless, we also address a potential conceptual link between consciousness and confidence that stems from Rosenthal’s very own work on mental quality space theory. (shrink)

The paper discusses the notion of reasoning with comparative moral judgements (i.e judgements of the form “act a is morally superior to act b”) from the point of view of several meta-ethical positions. Using a simple formal result, it is argued that only a version of moral cognitivism that is committed to the claim that moral beliefs come in degrees can give a normatively plausible account of such reasoning. Some implications of accepting such a version of (...) moral cognitivism are discussed. (shrink)

In this paper, I argue that -- contrary to widely received opinion -- logical arguments from evil are well and truly alive and kicking.

RESUMEN Se aborda el tema de la "racionalidad" en la versión estándar del enfoque pragmadialéctico, que pretende superar la dicotomía entre los aspectos normativo y descriptivo que existe en los estudios sobre argumentación. Se señala que la pragmadialéctica, al conceptualizar su noción de racionalidad, asume explícitamente ciertos postulados popperianos y, dado que aquella también incluye elementos de Searle y Grice, se indaga si las ideas de racionalidad de estos filósofos están presentes implícitamente en el compromiso con la racionalidad. A su (...) vez, se da cuenta de algunos nexos del pensamiento aristotélico con los planteamientos de Popper, Searle y Grice con el fin de aclarar la concepción de la racionalidad que tienen los pragmadialécticos, y de estimular un regreso enriquecedor a las fuentes de la argumentación. ABSTRACT The article addresses the issue of "rationality" in the standard version of the pragma-dialectic approach, which aims at overcoming the dichotomy between the normative and descriptive aspects that are evident in studies on argumentation. It points out that when conceptualizing its notion of rationality, pragma-dialectics explicitly assumes some of Popper's postulates. Given that said conceptualization also includes elements from Searle and Grice, the paper also inquires into whether these philosophers' ideas on rationality are implicitly present in the commitment to rationality. Likewise, it discusses some connections between Aristotelian thought and the formulations of Popper, Searle, and Grice, in order to clarify the pragma-dialectic conception of rationality and foster an enriching return to the sources of argumentation.

Se discuten dos argumentos del diálogo Protágoras sobre la relación entre las virtudes individuales. En primer lugar se defiende -frente a Terry Penner- la tesis de Vlastos de que cuando Sócrates dice que "la justicia es justa", "la justicia es piadosa", etc., está destacando la mutua implicación entre las virtudes, y no su identidad; y se formula una hipótesis para explicar la razón de tal reciprocidad. En segundo lugar, se examina el argumento de que, puesto que la insensatez se opone (...) tanto a la moderación como a la sabiduría, y un término contrario no puede tener más de un contrario, moderación y sabiduría serían "una sola cosa". Se asevera que Platón quiere que rechacemos esta última conclusión, basada en el fondo en la idea de que las distintas virtudes se relacionan entre sí como las partes de un mismo rostro. Se concluye que los argumentos analizados no implican realmente la idea contraintuitiva de la identifi cación mutua de las virtudes.Two arguments from the Protagoras on the unity of the virtues are here dwelt with. First, it is claimed - with G. Vlastos and contra T. Penner - that when Socrates says that “justice is just”, “justice is pious”, etc. he wants to highlight the reciprocity of the individual virtues, not their mutual identity . Second, it is argued that Plato does not really want us to infer from folly’s opposition to both temperance and wisdom the need to identify these two virtues . He is only drawing our attention to their close relationship. This is enough to reject the hypothesis initially defended by Protagoras, i.e. that the different virtues relate to each other as the parts of a face. I conclude that the two aforesaid arguments do not really support the mutual identity of the virtues. (shrink)

I put equality at the center of John Stuart Mill's practical philosophy. His principle of "perfect equality" embodies a substantive relational ideal, which I call "equality as reciprocity." This ideal requires removing injustices due to domination and subjection in human associations, including the family. Justice grounded on perfect equality must be the basis of personal, social, and political life, because the moral sentiments, chief among human beings' "higher" faculties, find adequate channels only under equality. Genuine happiness, which involves the (...) exercise and development of these faculties, is open only to those who relate as equals. Thus, on my account, equality as reciprocity adds substance to Mill's liberalism. ;In The Subjection of Women, Mill appealed to his view of human progress to argue for perfect equality. He maintained that this ideal is not appropriate for all times, but required for human improvement and a part of everyone's good under conditions of "modernity." Modern democratic cultures embrace such "progressive" human interests as equal justice, sympathy, and cooperation. Replacing the archaic command and obedience ethic with the nonhierarchical pattern of reciprocity would bring out human beings' "true virtue": living as equals. Inequality, and the exercise of unjust power generally, corrupts everyone's moral character and thwarts human flourishing. All other things equal, egalitarian relations are a critical part of anyone's autonomously chosen plan of life. Given human sociability, any other choice would impoverish a person's life. ;It is clear from Mill's argument for perfect equality that Mill was not a classical utilitarian. He conceived of utility broadly, as concerning progressive human interests, and argued for educating the "moral part" of human nature through just institutions and social practices. He believed that strengthening equal justice, the chief moral sentiment, is a central requirement of utility, because of the importance of other-regarding sentiments to a good human life. Thus, on my account, Mill's "enlarged" account of utility supports his substantive egalitarianism. His defense of perfect equality is utilitarian only in his idiosyncratic sense. (shrink)

I argue that modal epistemology should pay more attention to questions about the structure and function of modal thought. We can treat these questions from synchronic and diachronic angles. From a synchronic perspective, I consider whether a general argument for the epistemic support of modal though can be made on the basis of modal thoughs’s indispensability for what Enoch and Schechter (2008) call rationally required epistemic projects. After formulating the argument, I defend it from various (...) objections. I also examine the possibility of considering the indispensability of modal thought in terms of its components. Finally, I argue that we also need to approach these issues from a diachronic perspective, and I sketch how to approach this task. (shrink)

It is often said that our moral experience, broadly construed to include our ways of thinking and talking about morality, has a certain objective-seeming character to it, and that this supports a presumption in favor of objectivist theories and against anti-objectivist theories like Mackie’s error theory. In this paper, I argue that our experience of morality does not support objectivist moral theories in this way. I begin by arguing that our moral experience does not have the uniformly (...) objective-seeming character it is typically claimed to have. I go on to argue that even if moral experience were to presuppose or display morality as a realm of fact, we would still need a reason for taking that to support theories according to which it is such a realm. I consider what I take to be the four most promising ways of attempting to supply such a reason: inference to the best explanation, epistemic conservatism, the Principle of Credulity, and the method of wide reflective equilibrium. In each case, I argue, the strategy in question does not support a presumption in favor of objectivist moral theories. (shrink)

There is a familiar argument for the falsity of determinism, an argument that proceeds from the claim that agents are morally responsible. A number of authors have challenged the soundness of this argument. I pose a different challenge, one that grants its soundness. The challenge is that, given certain plausible assumptions, one cannot know the conclusion of this argument on the basis of knowing its premises. That is, one cannot know that determinism is false on (...) the basis of this argument even if agents are in fact morally responsible and moral responsibility is in fact incompatible with determinism. A slightly different version of the challenge tells also against the claim that one can be justified in believing that determinism is false on the basis of the argument, so that the challenge cannot be evaded by a retreat to an epistemic position weaker than knowledge. I compare my challenge to the challenge posed by the external world sceptic, and argue that there are asymmetries between these challenges that make it reasonable to accept the former and reject the latter. I close by considering the prospects for developing an epistemology of moral responsibility that is adequate to answer the challenge. (shrink)

The argument from moral psychology is one of the strongest arguments that non-cognitivists use against cognitivism-the metaethical position according to which our moral judgements express beliefs. According to this argument, once we put together the Humean theory of motivation and motivational internalism, we yield the conclusion that cognitivism cannot represent the correct view about the semantic function of moral discourse. I will first attempt to show that a neurological syndrome, called pain asymbolia (a rare (...) condition caused by lesions to the posterior insula that produces complete, thoroughgoing indifference to pain), can be used in order to formulate a persuasive defence of the Humean theory of motivation. After that, I will consider motivational internalism and argue that, without additional empirical evidence, neither internalism nor externalism can provide a plausible explanation of the connection between moral judgements and motivation. In conclusion, I intend to defend the claim that, until more persuasive arguments in favour of internalism are presented, non-cognitivists should not rely on the argument from moral psychology in their attempts to refute cognitivism.

It is a popular view thatpractical deliberation excludes foreknowledge of one's choice. Wolfgang Spohn and Isaac Levi have argued that not even a purely probabilistic self-predictionis available to thedeliberator, if one takes subjective probabilities to be conceptually linked to betting rates. It makes no sense to have a betting rate for an option, for one's willingness to bet on the option depends on the net gain from the bet, in combination with the option's antecedent utility, rather than on the (...) offered odds. And even apart from this consideration, assigning probabilities to the options among which one is choosing is futile since such probabilities could be of no possible use in choice. The paper subjects these arguments to critical examination and suggests that, appearances notwithstanding, practical deliberation need not crowd outself-prediction. (shrink)

Claims concerning the death of the nation-state are often accompanied by postnationalist arguments that emphasize the potential of human rights to contest nation-bounded conceptualizations of membership. Conversely, arguments focusing on the continuing importance of state-bounded social citizenship rights undermine such postnationalist claims. To assess these claims, this article turns to the Irish state and its prohibition of abortion except in cases where the life of the pregnant woman is in danger. The authors focus their analysis on four legal cases that (...) unfolded between 1992 and 2010. These cases reflect how specific women’s social location within interconnected power hierarchies of nationality, gender, class, race/ethnicity positioned them differently vis-a-vis the Irish state, international and supranational bodies. Furthermore, the transnational, in the form of immigration, non-governmental organizations and the Catholic Church, plays an important role in structuring the context within which these cases unfold. Rather than showing that the international, supranational and transnational are conduits for the declining power of the nation-state, this article finds that in the increasingly dense legal-political field there is room for all of these forces.

Conventional approaches to pluralistic thinking in bioethics usually attempt in one fashion or another to isolate and choose between the different perspectives. I would argue, however, that the essentialist and existentialist perspectives on the embryo each are internally self-consistent and ethically correct within their own framework and at the same time mutually exclusive. Therefore, we will Žnd no ethical high ground on which to base a choice. Rather, human embryo research will continue to be characterized by a multiplicity of views (...) that together create a state of holistic, dynamic tension, what has been called bioethical complementarity (Grinnell, Bishop, and McCullough 2002).

In the late 1990s, Mexican feminists mobilized transnationally to demand state accountability for the feminicidios of women in Ciudad Juarez. Feminicidio refers to the misogynous killing of women and the state’s complicity in this violence by tolerating it with impunity. Drawing on debates of the Mexican Federal Congress and interviews with feminist state and non-state actors, I examine feminist legislators’ response to transnational activism, which was to pass the “General Law on Women’s Access to a Life Free of Violence” and (...) to create the penal-type code of feminicidio, which includes provisions to punish negligent state actors. These laws make the state a target of its own punitive power. To pass these acts, feminist legislators faced resistance from male legislators and the Federal Executive. I build on feminist institutionalism to theorize this resistance as gendered. Gendered state resistance was pervasive because feminist legislators practiced accountability by identifying the complicity of state institutions, including Congress, in perpetuating feminicidio. As part of the process, they built alliances with other female legislators and framed their arguments with notions of modern statehood. Although this framing strategy resulted in innovative legal change, I interrogate the assumption that modernity is the solution to feminicidio, because it can lead gendered state resistance to manifest as a simulation of accountability.

In this article, I present a new interpretation of the pro-life view on the status of early human embryos. In my understanding, this position is based not on presumptions about the ontological status of embryos and their developmental capabilities but on the specific criteria of rational decisions under uncertainty and on a cautious response to the ambiguous status of embryos. This view, which uses the decision theory model of moral reasoning, promises to reconcile the uncertainty about the (...) ontological status of embryos with the certainty about normative obligations. I will demonstrate that my interpretation of the pro-life view, although seeming to be stronger than the standard one, has limited scope and cannot be used to limit destructive research on human embryos.

According to ‘Excluders’, descriptive uncertainty – but not normative uncertainty – matters to what we ought to do. Recently, several authors have argued that those wishing to treat normative uncertainty differently from descriptive uncertainty face a dependence problem because one's descriptive uncertainty can depend on one's normative uncertainty. The aim of this paper is to determine whether the phenomenon of dependence poses a decisive problem for Excluders. I argue that existing arguments fail to (...) show this, and that, while stronger ones can be found, Excluders can escape them. (shrink)

Explainable artificial intelligence has become a vitally important research field aiming, among other tasks, to justify predictions made by intelligent classifiers automatically learned from data. Importantly, efficiency of automated explanations may be undermined if the end user does not have sufficient domain knowledge or lacks information about the data used for training. To address the issue of effective explanation communication, we propose a novel information-seeking explanatory dialogue game following the most recent requirements to automatically generated explanations. Further, we generalise (...) our dialogue model in form of an explanatory dialogue grammar which makes it applicable to interpretable rule-based classifiers that are enhanced with the capability to provide textual explanations. Finally, we carry out an exploratory user study to validate the corresponding dialogue protocol and analyse the experimental results using insights from process mining and argument analytics. A high number of requests for alternative explanations testifies the need for ensuring diversity in the context of automated explanations. (shrink)

The most popular argument against moral realism is the argument from disagreement: if there are mind‐independent moral facts, then we would not expect to find as much moral disagreement as we in fact do; therefore, moral realism is false. In this paper, I develop the flipside of this argument. According to this argument from agreement, we would expect to find lots of moral disagreement if there were mind‐independent moral (...) facts. But we do not, in fact, find much moral disagreement; therefore, moral realism is false. I defend the argument, explain the empirical evidence that supports it, and show what makes this challenge novel and powerful. (shrink)

According to the argument from moral disagreement, the existence of widespread or persistent moral disagreement is best explained by, and thus supports, the view that there are no objective moral truths. One of the most common charges against this argument is that it “overgeneralises”: it implausibly forces its proponents to also deny the existence of objective truths about certain matters of physics, history, philosophy, etc. (“companions in guilt” objections) or even about the argument’s (...) own conclusion or its own soundness (“self-defeat” objections). My aim in this article is to provide a detailed clarification and assessment of this overgeneralisation charge. Various (mostly empirical) issues relevant to assessing the above objections have so far not been sufficiently investigated. Nevertheless, there are good reasons to believe that realists have exaggerated the significance of their overgeneralisation charge. Both its companions in guilt and its self-defeat versions likely fail. (shrink)

In this essay, we explore an issue of moral uncertainty: what we are permitted to do when we are unsure about which moral principles are correct. We develop a novel approach to this issue that incorporates important insights from previous work on moral uncertainty, while avoiding some of the difficulties that beset existing alternative approaches. Our approach is based on evaluating and choosing between option sets rather than particular conduct options. We show how our (...) approach is particularly well-suited to address this issue of moral uncertainty with respect to agents that have credence in moral theories that are not fully consequentialist.

Jennifer Rose Carr’s (2020) article “Normative Uncertainty Without Theories” proposes a method to maximize expected value under normative uncertainty without Intertheoretic Value Comparison (hereafter IVC). Carr argues that this method avoids IVC because it avoids theories: the agent’s credence is distributed among normative hypotheses of a particular type, which don’t constitute theories. However, I argue that Carr’s method doesn’t avoid or help to solve what I consider as the justificatory problem of IVC, which isn’t specific to comparing theories (...) as such. This threatens the implementability of Carr’s method. Fortunately, I also show how Carr’s method can nevertheless be implemented. I identify a type of epistemic states where the justificatory problem of IVC is not a necessary obstacle to maximizing expected value. In such states, the uncertainty stems from indecisive normative intuitions, and the agent justifiably constructs each normative hypothesis on the basis of a consistent subset of her intuitions by reference to the same unit of value. This part of my argument complements not only Carr’s (2020) argument, but also some moderate defenses of IVC. The combination of Carr’s paper and mine helps to illuminate the conditions for maximizing expected value under normative uncertainty without unjustified value comparison. (shrink)

We are sometimes unsure of the moral status of our relationships with other entities. Recent case studies in this uncertainty include our relationships with artificial agents (robots, assistant AI, etc.), animals, and patients with “locked-in” syndrome. Do these entities have basic moral standing? Could they count as true friends or lovers? What should we do when we do not know the answer to these questions? An influential line of reasoning suggests that, in such cases of moral (...) uncertainty, we need meta-moral decision rules that allow us to either minimize the risks of moral wrongdoing or improve the choice-worthiness of our actions. One particular argument adopted in this literature is the “risk asymmetry argument,” which claims that the risks associated with accepting or rejecting some moral facts may be sufficiently asymmetrical as to warrant favoring a particular practical resolution of this uncertainty. Focusing on the case study of artificial beings, this article argues that this is best understood as an ethical-epistemic challenge. The article argues that taking potential risk asymmetries seriously can help resolve disputes about the status of human–AI relationships, at least in practical terms (philosophical debates will, no doubt, continue); however, the resolution depends on a proper, empirically grounded assessment of the risks involved. Being skeptical about basic moral status, but more open to the possibility of meaningful relationships with such entities, may be the most sensible approach to take. (shrink)

The standard form of act-consequentialism requires us to perform the action with the best consequences; it allows choice between moral options only on those rare occasions when several actions produce equally good results. This paper argues for moral options and thus against act-consequentialism. The argument turns on the insight that some valuable things cannot exist unless our moral system allows options. One such thing is the opportunity for individuals to enact plans for their life from (...) among alternatives. Because planning one’s life has value, and because it requires moral options, a world governed by a moral system that admits of options is better than one governed by act-consequentialism. The paper argues that these facts entail that morality admits of a significant number of moral options; act-consequentialism is false. (shrink)

How should an agent decide what to do when she is uncertain not just about morally relevant empirical matters, like the consequences of some course of action, but about the basic principles of morality itself? This question has only recently been taken up in a systematic way by philosophers. Advocates of moral hedging claim that an agent should weigh the reasons put forward by each moral theory in which she has positive credence, considering both the likelihood that that (...) theory is true and the strength of the reasons it posits. The view that it is sometimes rational to hedge for one's moral uncertainties, however, has recently come under attack both from those who believe that an agent should always be guided by the dictates of the single moral theory she deems most probable and from those who believe that an agent's moral beliefs are simply irrelevant to what she ought to do. Among the many objections to hedging that have been pressed in the recent literature is the worry that there is no non-arbitrary way of making the intertheoretic comparisons of moral value necessary to aggregate the value assignments of rival moral theories into a single ranking of an agent's options. -/- This dissertation has two principal objectives: First, I argue that, contra these recent objections, an agent's moral beliefs and uncertainties are relevant to what she rationally ought to do, and more particularly, that agents are at least sometimes rationally required to hedge for their moral uncertainties. My principal argument for these claims appeals to the enkratic conception of rationality, according to which the requirements of practical rationality derive from an agent's beliefs about the objective, desire-independent value or choiceworthiness of her options. Second, I outline a new general theory of rational choice under moral uncertainty. Central to this theory is the idea of content-based aggregation, that the principles according to which an agent should compare and aggregate rival moral theories are grounded in the content of those theories themselves, including not only their value assignments but also the metaethical and other non-surface-level propositions that underlie, justify, or explain those value assignments.

What should a person do when, through no fault of her own, she ends up believing a false moral theory? Some suggest that she should act against what the false theory recommends; others argue that she should follow her rationally held moral beliefs. While the former view better accords with intuitions about cases, the latter one seems to enjoy a critical advantage: It seems better able to render moral requirements ‘followable’ or ‘action-guiding.’ But this tempting thought proves (...) difficult to justify. Indeed, whether it can be justified turns out to depend importantly on the rational status of epistemic akrasia. Furthermore, it can be argued, from premises all parties to the moral ignorance debate should accept, that rational epistemic akrasia is possible. If the argument proves successful, it follows that a person should sometimes act against her rationally held moral convictions. (shrink)

Sometimes it’s not certain which of several mutually exclusive moral views is correct. Like almost everyone, I think that there’s some sense in which what one should do depends on which of these theories is correct, plus the way the world is non-morally. But I also think there’s an important sense in which what one should do depends upon the probabilities of each of these views being correct. Call this second claim “moral uncertaintism”. In this paper, I want (...) to address an argument against moral uncertaintism offered in the pages of this journal by Brian Weatherson, and seconded elsewhere by Brian Hedden, the crucial premises of which are: that acting on moral uncertaintist norms necessarily involves motivation by reasons or rightness as such, and that such motivation is bad. I will argue that and are false, and that at any rate, the quality of an agent’s motivation is not pertinent to the truth or falsity of moral uncertaintism in the way that Weatherson’s and Hedden’s arguments require.

Facts about moral disagreement and human evolution have both been said to exclude the possibility of moral knowledge, but the question of how these challenges interact has largely gone unaddressed. The paper aims to present and defend a novel version of the evolutionary “debunking” argument for moral skepticism that appeals to both types of considerations. This argument has several advantages compared to more familiar versions. The standard debunking strategy is to argue that evolutionary accounts of (...) moral beliefs generate skeptical implications because they attribute those beliefs to factors that are unrelated to their truth. That strategy is vulnerable to “third-factor” responses, which invoke first-order moral claims to challenge the assumption that Darwinian factors and the moral truths are really unrelated in that way. In contrast, our version is immune to those responses, as it does not proceed via assumptions about how Darwinian factors relate to the moral facts. Instead, it focuses on what evolutionary accounts of moral beliefs have to say about the fact that people often reach divergent moral beliefs. The argument thereby illustrates how the debunking strategy can join forces with the argument from moral disagreement. The combination of those strategies presents, we think, a challenge that is more formidable than when they are considered separately. (shrink)

Metaethical constructivists have proposed many arguments against mind-independence moral realism. In this paper I resume the constructivist critique against realism on the grounds of considerations stemming from moral phenomenology. My claim is that constructivism, in contrast to moral mind-independence theories such as moral realism or quasi-realism, fares better in accounting for the phenomenology of moral practice and discourse. Given the importance of phenomenological investigation for metaethical theorizing as such, my argument shows that there (...) is good reason to prefer constructivism over any kind of theory that endorses the mind-independence of morality.

In decision-making based on multiple criteria, situations may arise where agents find their options to be neither better than, worse than nor equal to each other with respect to the relevant criteria. How, if at all, can a justified choice be made between such options? Are the options incomparable? This article explores a hypothetical case that illustrates how such a situation can arise in an environmental context; more specifically, it considers the deliberations of an imagined 'ethics committee' as it struggles (...) to decide whether or not a deep-sea mining project should be allowed to proceed. I argue that the case is best understood as involving options that are comparable in the sense of being 'on a par'. Working out from a discussion of Ruth Chang's 'self-governance' theory of choice in cases of parity, I suggest that, in the environmental context, the idea of choices expressing a moral identity may lead us in the direction of a plausible solution to these particularly challenging cases.

A long-standing family of worries about moral realism focuses on its implications for moral epistemology. The underlying concern is that if moral truths have the nature that realists believe, it is hard to see how we could know what they are. This objection may be called the “argument from skepticism” against moral realism. Realists have primarily responded to this argument by presenting accounts of how we could acquire knowledge of moral truths that (...) are consistent with realist assumptions about their nature. Less time has been spent, however, on the question of why it would be a problem for moral realism if it leads to skepticism in the first place, and on the related question of which skeptical conclusions it would be problematic for realists to simply accept. This paper considers several answers to these questions, thereby distinguishing a number of versions of the argument from skepticism, and discusses their prospects. (shrink)

In this dialogue, I illustrate why moral arguments from analogy are a valuable part of moral reasoning by considering how texting while driving is, morally speaking, no different than drunk driving.

The argument from relevance expresses an intuition that, although shared by many applied ethicists, has not been analyzed and systematized in the form of a clear argument thus far. This paper does this by introducing the concept of value relevance, which has been used before in economy but not in the philosophical literature. The paper explains how value relevance is different from moral relevance, and distinguishes between direct and indirect ways in which the latter can (...) depend on the former. These clarifications allow the argument to explain in detail how we can make two claims. The first one is that being a recipient of value should be the only criterion for full moral considerability. This follows if we accept that value relevance should determine, directly or indirectly, moral relevance. The second claim is that, given what the main theories of wellbeing imply regarding what entities can be recipients of value, sentience is both a sufficient and a necessary criterion for full moral considerability. The paper argues that this conclusion stands even if we hold views that consider other values different from sentience. (shrink)
