Traditional discussions about the arrow of time in general involve the concept of entropy. In the cosmological context, the direction past-to-future is usually related to the direction of the gradient of the entropy function of the universe. But the definition of the entropy of the universe is a very controversial matter. Moreover, thermodynamics is a phenomenological theory. Geometrical properties of space-time provide a more fundamental and less controversial way of defining an arrow of time for the universe as a whole. (...) We will call the arrow defined only on the basis of the geometrical properties of space-time, independently of any entropic considerations, “the global arrow of time.” In this paper we will argue that: (i) if certain conditions are satisfied, it is possible to define a global arrow of time for the universe as a whole, and (ii) the standard models of contemporary cosmology satisfy these conditions.

There seem to be good reasons to think that there must be body representations or some kind of body content required for riding a bike or grabbing a cup of coffee. However, when I ride a bike or grab a cup of coffee, am I just representing the bike and the cup? Or am I actually also representing my body and bodily movements? The thesis of this paper is that the body not only figures in the content that guides everyday (...) activities but that it must. How is this possible? Exactly what elements of the subject’s body can be said to figure in this content? I will proceed in three steps: in the first, I bring together the conceptual resources that seem to be required; in the second, I discuss a couple of proposals about how to link the notion of affordance and the topic of bodily representations, arguing that they are misguided; finally, I propose a view according to which the body’s physical and spatial properties are an unavoidable part of the content that guides everyday activities.

¿Necesitamos representaciones del cuerpo para llevar a cabo actividades como cruzar la calle, montar en bicicleta o salir por la puerta? En este trabajo se defiende la idea de que la ejecución de este tipo de acciones involucra representaciones del cuerpo con contenido no conceptual. Primero se discuten los argumentos en contra de la noción de representación del cuerpo en la acción, para extraer sus principales consecuencias. Se propone una versión delcontenido de las representaciones del cuerpo involucradas en la acción (...) cotidiana, y se finaliza con una discusión acerca de una objeción potencial, y con una reflexión sobre la relación entre contenido conceptual y contenido no conceptual.

Scientific cosmology is an empirical discipline whose objects of study are the large-scale properties of the universe. In this context, it is usual to call the direction of the expansion of the universe the "cosmological arrow of time". However, there is no reason for privileging the ‘radius’ of the universe for defining the arrow of time over other geometrical properties of the space-time. Traditional discussions about the arrow of time in general involve the concept of entropy. In the cosmological context, (...) the direction past-to-future is usually related to the direction of the gradient of the entropy function of the universe. But entropy is a thermodynamic magnitude that is typically associated with subsystems of the universe: the entropy of the universe as a whole is a very controversial matter. Moreover, thermodynamics is a phenomenological theory. Geometrical properties of space-time provide a more fundamental and less controversial way of defining an arrow of time for the universe as a whole. We will call the arrow defined only on the basis of the geometrical properties of space-time, independently of any entropic considerations, the "cosmological arrow of time". In this paper we will argue that: (i) it is possible to define a cosmological arrow of time for the universe as a whole, if certain conditions are satisfied, and (ii) the standard models of contemporary cosmology satisfy these conditions.

Lara Buchak sets out a new account of rational decision-making in the face of risk. She argues that the orthodox view is too narrow, and suggests an alternative, more permissive theory: one that allows individuals to pay attention to the worst-case or best-case scenario, and vindicates the ordinary decision-maker.

There are currently two robust traditions in philosophy dealing with doxastic attitudes: the tradition that is concerned primarily with all-or-nothing belief, and the tradition that is concerned primarily with degree of belief or credence. This paper concerns the relationship between belief and credence for a rational agent, and is directed at those who may have hoped that the notion of belief can either be reduced to credence or eliminated altogether when characterizing the norms governing ideally rational agents. It presents a (...) puzzle which lends support to two theses. First, that there is no formal reduction of a rational agent’s beliefs to her credences, because belief and credence are each responsive to different features of a body of evidence. Second, that if our traditional understanding of our practices of holding each other responsible is correct, then belief has a distinctive role to play, even for ideally rational agents, that cannot be played by credence. The question of which avenues remain for the credence-only theorist is considered. (shrink)

This paper provides an account of what it is to have faith in a proposition p, in both religious and mundane contexts. It is argued that faith in p doesn’t require adopting a degree of belief that isn’t supported by one’s evidence but rather it requires terminating one’s search for further evidence and acting on the supposition that p. It is then shown, by responding to a formal result due to I.J. Good, that doing so can be rational in a (...) number of circumstances. If expected utility theory is the correct account of practical rationality, then having faith can be both epistemically and practically rational if the costs associated with gathering further evidence or postponing the decision are high. If a more permissive framework is adopted, then having faith can be rational even when there are no costs associated with gathering further evidence. (shrink)

The ‘rollback argument,’ pioneered by Peter van Inwagen, purports to show that indeterminism in any form is incompatible with free will. The argument has two major premises: the first claims that certain facts about chances obtain in a certain kind of hypothetical situation, and the second that these facts entail that some actual act is not free. Since the publication of the rollback argument, the second claim has been vehemently debated, but everyone seems to have taken the first claim for (...) granted. Nevertheless, the first claim is totally unjustified. Even if we accept the second claim, therefore, the argument gives us no reason to think that free will and indeterminism are incompatible. Furthermore, seeing where the rollback argument goes wrong illuminates how a certain kind of incompatibilist, the ‘chance-incompatibilist,’ ought to think about free will and chance, and points to a possibility for free will that has remained largely unexplored.

The moral enhancement of human beings is a constant theme in the history of humanity. Today, faced with the threats of a new, globalised world, concern over this matter is more pressing. For this reason, the use of biotechnology to make human beings more moral has been considered. However, this approach is dangerous and very controversial. The purpose of this article is to argue that the use of another new technology, AI, would be preferable to achieve this goal. Whilst several (...) proposals have been made on how to use AI for moral enhancement, we present an alternative that we argue to be superior to other proposals that have been developed. (shrink)

María Pía Lara explores the ambiguity of secularization and the theoretical potential of a structural break between politics and religion.

Turning to such philosophers and writers as Jürgen Habermas, Walter Benjamin, Primo Levi, Giorgio Agamben, and Ariel Dorfman, Lara defines a reflexive relationship between an event, the narrative of the event, and the public reception of ...

It is sometimes said that faith is recalcitrant in the face of new evidence, but it is puzzling how such recalcitrance could be rational or laudable. I explain this aspect of faith and why faith is not only rational, but in addition serves an important purpose in human life. Because faith requires maintaining a commitment to act on the claim one has faith in, even in the face of counter-evidence, faith allows us to carry out long-term, risky projects that we (...) might otherwise abandon. Thus, faith allows us to maintain integrity over time. (shrink)

Decision theory has at its core a set of mathematical theorems that connect rational preferences to functions with certain structural properties. The components of these theorems, as well as their bearing on questions surrounding rationality, can be interpreted in a variety of ways. Philosophy’s current interest in decision theory represents a convergence of two very different lines of thought, one concerned with the question of how one ought to act, and the other concerned with the question of what action consists (...) in and what it reveals about the actor’s mental states. As a result, the theory has come to have two different uses in philosophy, which we might call the normative use and the interpretive use. It also has a related use that is largely within the domain of psychology, the descriptive use. This essay examines the historical development of decision theory and its uses; the relationship between the norm of decision theory and the notion of rationality; and the interdependence of the uses of decision theory.

A natural view in distributive ethics is that everyone's interests matter, but the interests of the relatively worse off matter more than the interests of the relatively better off. I provide a new argument for this view. The argument takes as its starting point the proposal, due to Harsanyi and Rawls, that facts about distributive ethics are discerned from individual preferences in the "original position." I draw on recent work in decision theory, along with an intuitive principle about risk-taking, to (...) derive the view. (shrink)

In “Can it be rational to have faith?”, it was argued that to have faith in some proposition consists, roughly speaking, in stopping one’s search for evidence and committing to act on that proposition without further evidence. That paper also outlined when and why stopping the search for evidence and acting is rationally required. Because the framework of that paper was that of formal decision theory, it primarily considered the relationship between faith and degrees of belief, rather than between faith (...) and belief full stop. This paper explores the relationship between rational faith and justified belief, by considering four prominent proposals about the relationship between belief and degrees of belief, and by examining what follows about faith and belief according to each of these proposals. It is argued that we cannot reach consensus concerning the relationship between faith and belief at present because of the more general epistemological lack of consensus over how belief relates to rationality: in particular, over how belief relates to the degrees of belief it is rational to have given one’s evidence.

Some early phase clinical studies of candidate HIV cure and remission interventions appear to have adverse medical risk–benefit ratios for participants. Why, then, do people participate? And is it ethically permissible to allow them to participate? Recent work in decision theory sheds light on both of these questions, by casting doubt on the idea that rational individuals prefer choices that maximise expected utility, and therefore by casting doubt on the idea that researchers have an ethical obligation not to enrol participants (...) in studies with high risk–benefit ratios. This work supports the view that researchers should instead defer to the considered preferences of the participants themselves. This essay briefly explains this recent work, and then explores its application to these two questions in more detail. (shrink)

This paper addresses the question of whether gathering additional evidence is always rationally required, both from the point of view of instrumental rationality and of epistemic rationality. It is shown that in certain situations, it is not instrumentally rational to look for more evidence before making a decision. These are situations in which the risk of “misleading” evidence – a concept that has both instrumental and epistemic senses – is not offset by the gains from the possibility of non-misleading evidence. (...) These situations also undermine a particular argument for the claim that it is epistemically rational to look for more evidence, though it is argued that the relationship between instrumental and epistemic rationality makes such arguments flawed to begin with. Furthermore, these situations show us that our epistemic and our practical goals sometimes point us in different directions, not merely because of our limited resources or because our desires are sometimes best served by being in particular epistemic states, but because of the nature of rational action.

En este libro, la autora desarrolla su concepción del juicio reflexionante inspirada en Emmanuel Kant y en Hannah Arendt para concentrarse en cómo cierto tipo de narraciones modelan nuestras nociones de lo que consideramos moral. Lara nos ofrece distintas concepciones sobre el mal en su formulación histórica mediante los ejemplos de las tragedias griegas, las diferentes concepciones sobre el mal en la obra de Shakespeare, el uso literario de la metáfora en la obra de Joseph Conrad y en narraciones (...) fílmicas que describen la crueldad humana. Lara sugiere que el aprendizaje moral es un proceso en el que intervienen las instituciones sociales, la voluntad de los individuos y de las sociedades para comprometerse a un debate abierto y con ello modelar los juicios colectivos sobre el pasado. Lara enfatiza que el juicio reflexionante se da entre un evento, una narración de dicho evento y la recepción pública de dicha narrativa. En este libro se aportan importantes métodos para la comprensión del fenómeno moral del mal, porque introducen nuevas verdades desvelatorias acerca de eventos particulares que no pueden ser simplemente captados por medio de categorías conceptuales. Lara utiliza como fuentes a Jürgen Habermas, Walter Benjamin, Primo Levi, Giorgio Agamben y Ariel Dorfman para probar la conclusión de este tipo de narraciones: la acción (de crueldad) ata de manera definitiva al perpetrador con su víctima.

Faith is a central attitude in Christian religious practice. The problem of faith and reason is the problem of reconciling religious faith with the standards for our belief-forming practices in general (‘ordinary epistemic standards’). In order to see whether and when faith can be reconciled with ordinary epistemic standards, we first need to know what faith is. This chapter examines and catalogues views of propositional faith: faith that p. It is concerned with the epistemology of such faith: what cognitive attitudes (...) does such faith require, what epistemic norms govern these attitudes, and whether Christian faith can ever adhere to them.

I have claimed that risk-weighted expected utility maximizers are rational, and that their preferences cannot be captured by expected utility theory. Richard Pettigrew and Rachael Briggs have recently challenged these claims. Both authors argue that only EU-maximizers are rational. In addition, Pettigrew argues that the preferences of REU-maximizers can indeed be captured by EU theory, and Briggs argues that REU-maximizers lose a valuable tool for simplifying their decision problems. I hold that their arguments do not succeed and that my original (...) claims still stand. However, their arguments do highlight some costs of REU theory. (shrink)

Immanuel Kant's Metaphysics of Morals, containing the Doctrine of Right and Doctrine of Virtue, is his final major work of practical philosophy. Its focus is not rational beings in general but human beings in particular, and it presupposes and deepens Kant's earlier accounts of morality, freedom and moral psychology. In this volume of newly-commissioned essays, a distinguished team of contributors explores the Metaphysics of Morals in relation to Kant's earlier works, as well as examining themes which emerge from the text (...) itself. Topics include the relation between right and virtue, property, punishment, and moral feeling. Their diversity of questions, perspectives and approaches will provide new insights into the work for scholars in Kant's moral and political theory. (shrink)

This paper examines Kant’s accounts of friendship and marriage, and argues for what can be called an ideal of “moral marriage” based on Kant’s notion of moral friendship. After explaining why Kant values friendship so highly, it gives an account of the ways in which marriage falls far short, according to Kant, of what friendship has to offer. The paper then argues that many of Kant’s reasons for finding marriage morally impoverished compared with friendship are wrong-headed. The paper further argues (...) that a few of Kant’s views about friendship are false. The main point is that, when we slightly revise Kant’s account of friendship and jettison Kant’s misguided notions about marriage, we see that marriages can aspire to much of the same moral richness as friendships. Finally, the paper argues that this friendship model of marriage does not obscure the important ways in which marriages and friendships differ. (shrink)

In this paper I argue that, on Kant's view, the work of genius serves as a sensible exhibition of the Idea of the highest good. In other words, the work of genius serves as a special sign that the world is hospitable to our moral ends and that the realization of our moral vocation in such a world may indeed be possible. In the first part of the paper, I demonstrate that the purpose of the highest good is not to (...) strengthen our motivation to accept the moral law as binding for us but, rather, to strengthen our motivation to persist in our already existent moral dispositions. In the second part, I show that the works of genius exhibit the Idea of the highest good and, consequently, strengthen our hope in its realization. Drawing on the results of the second part, the third part of the paper demonstrates that beauty, of both art and nature, symbolizes morality in a more substantive sense than that suggested by Henry Allison's “formalistic” interpretation. Since, on my view, fine art in Kant serves as a sensible representation of an undetermined conceptual content, or the Idea of the highest good, the fourth part of the paper addresses the vexed question of whether Kant's account of fine art already anticipates the cognitive role later attributed to it by the German Idealists.

In this paper, I explicate Kant’s theory of virtue and situate it within the context of theories of virtue before Kant (such as Aristotle, Hobbes, and Hume) and after Kant (such as Schiller and Schopenhauer). I explore Kant’s notions of virtue as a disposition to do one’s duty out of respect for the moral law, as moral strength in non-holy wills, as the moral disposition in conflict, and as moral self-constraint based on inner freedom. I distinguish between Kant’s notions of (...) virtue and of the good will. I discuss Kant’s duties of virtue (and so particular virtues and vices), the relationships between virtue and happiness and virtue and the emotions, and Kant’s criticisms of his predecessors’ views of virtue. I close with a discussion of Kant and contemporary virtue ethics. Although the paper reflects my own interpretation of Kant, it strives less to argue for a particular thesis about Kant on virtue than to illuminate important aspects of Kant’s theory of virtue.

This paper investigates the nature and foundation of duties to oneself in Kant's moral theory. Duties to oneself embody the requirement of the formula of humanity that agents respect rational nature in them-selves as well as in others. So understood, duties to oneself are not subject to the sorts of conceptual objections often raised against duties to oneself; nor do these duties support objections that Kant's moral theory is overly demanding or produces agents who are preoccupied with their own virtue. (...) Duties to oneself emerge as an essential and compelling part of Kant's moral theory. (shrink)

The orthodox theory of instrumental rationality, expected utility (EU) theory, severely restricts the way in which risk-considerations can figure into a rational individual's preferences. It is argued here that this is because EU theory neglects an important component of instrumental rationality. This paper presents a more general theory of decision-making, risk-weighted expected utility (REU) theory, of which expected utility maximization is a special case. According to REU theory, the weight that each outcome gets in decision-making is not the subjective probability (...) of that outcome; rather, the weight each outcome gets depends on both its subjective probability and its position in the gamble. Furthermore, the individual's utility function, her subjective probability function, and a function that measures her attitude towards risk can be separately derived from her preferences via a Representation Theorem. This theorem illuminates the role that each of these entities plays in preferences, and shows how REU theory explicates the components of instrumental rationality. (shrink)

This essay argues that when setting climate policy, we should place more weight on worse possible consequences of a policy, while still placing some weight on better possible consequences. The argument proceeds by elucidating the range of attitudes people can take towards risk, how we must make choices for people when we don’t know their risk-attitudes, and the situation we are in with respect to climate policy and the consequences for future people. The result is an alternative to the Precautionary (...) Principle, an alternative that gives similar policy recommendations in many cases but is also sensitive to the costs of precautions. (shrink)

Some Kantian ethicists, myself included, have been trying to show how, contrary to popular belief, Kant makes an important place in his moral theory for emotions–especially love and sympathy. This paper confronts claims of Kant that seem to endorse an absence of sympathetic emotions. I analyze Kant’s accounts of different sorts of emotions (“affects,” “passions,” and “feelings”), and different sorts of emotional coolness (“apathy,” “self-mastery,” and “cold-bloodedness”). I focus on the particular way that Kant praises apathy, as “sublime,” in order (...) to argue that his praise of extreme emotional self-control is not incompatible with, but rather complementary to, his praise of sympathy.

My book Risk and Rationality argues for a new alternative to the orthodox theory of rational decision-making. This alternative, risk-weighted expected utility maximization, holds that there are three important components involved in rational decision-making: utilities, probabilities, and risk-attitudes. This essay explains the basic outline of the theory and precisely how it differs from the orthodox theory. It also summarizes the main threads of argument in the book.

I reply to two commentaries—one by Johanna Thoma and Jonathan Weisberg and one by James M. Joyce—concerning how risk-weighted expected utility theory handles the Allais preferences and Dutch books.
