Nobody's going to object to the advice "Do the right thing", but that doesn't mean everyone's always going to follow it. Sometimes this is because of our volitional limitations; we cannot always bring ourselves to make the sacrifices that right action requires. But sometimes this is because of our cognitive limitations; we cannot always be sure of what is right. Sometimes we can't be sure of what's right because we don't know the non-normative facts. But sometimes, even if we were (...) to know all of the non-normative facts, we'd still not be sure about what's right, because we're uncertain about the normative reasons those facts give us. In this dissertation, I attempt to answer the question of what we're to do when we must act under fundamentally normative uncertainty. It's tempting to think that, in such circumstances, we should do what we regard as most probably right. I argue that this view is mistaken, for it is insensitive to how degrees of actions' values compare across different normative hypotheses; if an action is probably right, but, if wrong, is terribly, terribly, wrong, it may be rational not to do that action. A better answer is that we should do the action with the highest expected value. I spend the first part of the dissertation providing arguments for and rebutting arguments against this view of action under normative uncertainty. I spend the next part of the dissertation explaining what degrees of value are, and showing how they can be compared across normative hypotheses. In the remaining parts of the dissertation, I consider two questions related to our primary question -- first, what is one required, or obligated, to do under normative uncertainty; and second, what is it rational for one to do when one is not only normatively uncertain in the way we've been discussing, but also uncertain about what it is rational to do under this sort of normative uncertainty.

An argument for the eponymous conclusion is given through a series of hypothetical syllogisms, the most basic of which is as follows: morality is necessary for self-respect; self-respect is necessary for happiness; therefore, morality is necessary for happiness. Some of the most obvious objections are entertained and rejected.

Are there such things as moral truths? How do we know what we should do? And does it matter? Constructivism states that moral truths are neither invented nor discovered, but rather are constructed by rational agents in order to solve practical problems. While constructivism has become the focus of many philosophical debates in normative ethics, meta-ethics and action theory, its importance is still to be fully appreciated. These new essays written by leading scholars define and assess this new approach in (...) ethics, addressing such questions as the nature of constructivism, how constructivism improves our understanding of moral obligations, how it accounts for the development of normative practices, whether moral truths change over time, and many other topics. The volume will be valuable for advanced students and scholars of ethics and all who are interested in questions about the foundation of morality. (shrink)

What does it take for lawyers and others to think or talk about the same legal topic—e.g., defamation, culpability? We argue that people are able to think or talk about the same topic not when they possess a matching substantive understanding of the topic, as traditional metasemantics says, but instead when their thoughts or utterances are related to each other in certain ways. And what determines the content of thoughts and utterances is what would best serve the core purposes of (...) the representational practice within which the thought or utterance is located. In thus favoring a “relational model” in metasemantics, we share Ronald Dworkin's goal of explaining fundamental legal disagreements, and also his reliance on constructive interpretation. But what we delineate is a far more general and explanatorily resourceful metasemantics than what Dworkin articulated, which also bypasses some controversial implications for the nature of law that Dworkin alleged.

In a series of influential essays, Sharon Street has argued, on the basis of Darwinian considerations, that normative realism leads to skepticism about moral knowledge. I argue that if we begin with the account of moral knowledge provided by Aristotelian naturalism, then we can offer a satisfactory realist response to Street’s argument, and that Aristotelian naturalism can avoid challenges facing other realist responses. I first explain Street’s evolutionary argument and three of the most prominent realist responses, and I identify challenges (...) to each of those responses. I then develop an Aristotelian response to Street. My core claim is this: Given Aristotelian naturalism’s account of moral truth and our knowledge of it, we can accept the influence of evolutionary processes on our moral beliefs, while also providing a principled, non-question-begging reason for thinking that those basic evaluative tendencies that evolution has left us with will push us toward, rather than away from, realist moral truths, so that our reliably getting things right does not require an unexplained and implausible coincidence.

Religions don’t simply make claims about the world; they also offer existential resources, resources for dealing with basic human problems, such as the need for meaning, love, identity, and personal growth. For instance, a Buddhist’s resources for addressing these existential needs are different than a Christian’s. Now, imagine someone who is agnostic but who is deciding whether to put faith in religion A or religion B. Suppose she thinks A and B are evidentially on par, but she regards A as (...) offering much more by way of existential resources. Is it epistemically rational for her to put her faith in A rather than B on this basis? It is natural to answer No. After all, what do the existential resources of a religion have to do with its truth? However, I argue that this attitude is mistaken. My thesis is that the extent to which it is good for a certain religion to be true is relevant to the epistemic rationality of faith in that religion. This is plausible, I’ll argue, on the correct account of the nature of faith, including the ways that emotion and desire can figure into faith and contribute to its epistemic rationality. (shrink)

Moral discourse allows for speakers to disagree in many ways: about right and wrong acts, about moral theory, about the rational and conative significance of moral failings. Yet speakers’ eccentricities do not prevent them from engaging in moral conversation or from having (genuine, not equivocal) moral disagreement. Thus differences between speakers are compatible with possession of moral concepts. This paper examines various kinds of moral disagreements and argues that they provide evidence against conceptual-role and informational atomist approaches to understanding our (...) moral concepts. Conceptual role approaches fail because they cannot account for shared concepts among speakers with different commitments to the practical and conative ramifications of moral judgments. Informational atomist views fail because speakers need not be locked on to the same moral properties to share moral concepts. (shrink)

A shared presumption among practice-dependent theorists is that a principle of justice is dependent on the function or aim of the practice to which it is supposed to be applied. In recent contributions to this debate, the condition of epistemic uncertainty plays a significant role for motivating and justifying a practice-dependent view. This paper analyses the role of epistemic uncertainty in justifying a practice-dependent approach. We see two kinds of epistemic uncertainty allegedly playing this justificatory role. What we call ‘normative (...) epistemic uncertainty’ emerges from dealing with the problem of value uncertainty in justifying applied principles when our higher-level principles are open-textured, that is, when their content is too vague or unclear to generate determinate prescriptions. What we call ‘descriptive epistemic uncertainty’ emerges from dealing with uncertainty about empirical facts, such as the problem of moral assurance, that is, the problem that the requirements of justice cannot go beyond arrangements that we can know with reasonable confidence that we can jointly establish and maintain. In both cases, practice-dependent theorists conclude that the condition of epistemic uncertainty justifies a practice-dependent approach, which puts certain restrictions on theorizing regulative principles and has wide-ranging practical implications for the scope of justice. Our claim in this paper is that neither kind of epistemic uncertainty justifies a practice-dependent approach. (shrink)

In this paper, I argue that an externalist theory of thought content provides the means to resolve two debates in moral philosophy. The first—that between judgement internalism and judgement externalism—concerns the question of whether there is a conceptual connection between moral judgement and motivation. The second—that between reasons internalism and reasons externalism—concerns the relationship between moral reasons and an agent's subjective motivational set. The resolutions essentially stem from the externalist claim that concepts can be grasped partially, and a new moral (...) theory, which I call ‘moral externalism’, emerges. (shrink)

This essay examines the manner in which Hume challenges the cognitivist and realist intuitions informing our ordinary experience of value by identifying values with mind-dependent feelings and by separating facts from values. However, through a process of interpretive rehearsal of Hume’s arguments in the first two parts of the paper we find that they come under increasing internal strain, which points, contrary to his initial argument about the irreducibly phenomenal aspects of value experience, to the motivational role of reason and (...) to the identification of values, not with mind-dependent feelings, but with dispositional properties of objects. The third and final part of the paper will offer a systematic reconstruction of his arguments with a view to suggesting one possible – descriptivist – alternative to Hume’s initial challenges, which can serve to satisfy the emerging cognitivist and realist needs of his arguments.

While the modern revival of virtue ethics largely looks back to Aristotle, most, if not all, versions of this trend continue to be much indebted to and/or based upon specific mid‐twentieth‐century neo‐naturalist and descriptivist critiques of prevailing antinaturalist trends of that time: specifically, upon Anscombe's critique of the ethics of duty and utility and of the so‐called modern moral ought, and Geach's robust defence of the descriptive character of moral and other goodness. However, in the wake of further critical attention (...) to these neo‐naturalist claims, this paper argues that there can ultimately be no reliable or secure logical or empirical grounding of the virtues of inherently normative human moral life and conduct in the goods or virtues of effective or even beneficial natural function.

Adviser: Professor Stefan Baumrin In the first chapter I introduce the distinction between metaethics and normative ethics and argue that metaethics, properly conceived, is a part of cognitive science. For example, the debate between rationalism and sentimentalism can be informed by recent empirical work in psychology and the neurosciences. In the second chapter I argue that the traditional view that one’s theory of semantics determines what one’s theory of justification must be is mistaken. Though it has been the case that (...) there are ‘typical’ combinations of semantic and justificational theories this is by no means forced on one. In the third chapter I examine two current kinds of expressivism; that of Blackburn and Copp. Each gives us an example of different combinations of semantic and justificatory theory. In Blackburn’s case he combines a use theory of meaning with a classic emotivist theory of justification, In Copp’s case it is a neo-Gricean philosophy of language with a realist’s theory of justification. I find both of these wanting as they ultimately collapse into relativistic subjectivism. In the fourth and fifth chapter I turn to developing Emotive Realism. The basic idea behind this view is that when someone says ‘x is wrong/right’ that person has (a) expressed a moral emotion about x and at the same time (b) expressed the belief that the emotion in (a) is the correct one to have. The belief expressed in (b) will be true or false depending on one’s theory of justification. In the fourth chapter I argue that we need separate semantic theories for thoughts and sentences. In the fifth chapter I fill in the details of Emotive Realism as I see it. (shrink)

Justice for children meets specific obstacles when it comes to its realization due not only to the nature of rights and the peculiarities of children as subjects of rights. The conflict of interests between short-term and long-term aims, and the different interpretations a state can do on the question concerning how to materialize social rights policies and how to interpret its commitments on social justice play also a role. Starting by the question on why the affluent states do not seem (...) to be motivated enough to fully assume those duties of justice toward children —derived form recognizing children’s rights—, this article aims to explore and shed light on what psychology of motivation and moral psychology, and positive approaches could offer in relation to political and ethical challenges toward childhood. Hence this article advocates for the modification and enrichment of the philosophical discourse on children’s rights with what psychology has proved to have a more efficient impact in agents’ action and motivation. In doing so, practical philosophy could improve its role helping understand and eventually surpassing some akratic tendencies in the public sphere with respect to children’s rights. (shrink)

In this dissertation I discuss the epistemology of ethical intuitionism, in particular the claim that mature moral agents possess self-evident moral knowledge. Traditional intuitionists such as W.D. Ross have claimed that by reflection, we can acquire knowledge of our basic moral duties such as the duty of veracity or benevolence. Recent defenders of intuitionism such as Robert Audi have further developed this theory and argued that adequate understanding can be sufficient for moral knowledge. I criticize this view and argue that (...) such accounts fail to make a convincing case for a foundationalist moral epistemology. Instead, I propose to separate the question of how we acquire moral knowledge from an account that justifies moral beliefs. In response to the first issue, I draw an analogy between our moral intuitions and chosmkian linguistics; in both areas, I argue, human beings possess a universal, unconscious and (partly) inaccessible system of rules that explains how we come to learn language and to make moral judgments. In regards to the justificatory issue, I address recent evolutionary debunking arguments designed to undermine the claim that our moral judgments track stance-independent truths. I try to show that this conclusion only follows under the assumption of an instrumentalist interpretation of moral reasoning which the intuitionist is not forced to accept. (shrink)

We elucidate the conditions under which any hypothesis is explanatorily relevant by analyzing several tests of explanatory relevance and explanations based on those tests. A new causal criterion of explanatory relevance is developed and defended. We show how the causal criterion succeeds in establishing, at the very least, a very strong presumption against moral facts.

Para quienes tengan interés en la filosofía moral y política contemporánea la obra de John Rawls es sin discusión una parada necesaria. De hecho, la tesis de Robert Nozick según la cual resulta imposible hacer filosofía moral y política sin considerar el marco ofrecido por Rawls, aunque parezca extrema, resulta bastante acertada. En gran medida el impacto de la obra de Rawls radica en su interés por ofrecer una teoría sustantiva de la justicia, teoría que hundiendo sus raíces en la (...) tradición de la filosofía sea capaz de orientarnos al momento de abordar las discusiones contemporáneas sobre justicia social. -/- En los trabajos que componen este libro el lector podrá encontrar una discusión actualizada sobre aquellos elementos que definen la base moral y política que Rawls presentó como fundamento de su teoría de la justicia. Al mismo tiempo, estos ensayos intentan construir un puente entre la justicia como equidad y otras tradiciones de la filosofía moral y política contemporánea. Para lograr este último fin, varios de los trabajos que aquí se presentan consideran las ideas de reconocimiento y autorrespeto como claves de interpretación de la obra de Rawls. (shrink)
