Aspects of Value

Philosophers such as Plato, Aristotle, Kant, Brentano, Moore, and Chisholm suggest marks of intrinsic value. Contemporary philosophers such as Christine Korsgaard have insightful discussions of intrinsic value. But how do we verify that some specific thing really is intrinsically valuable? I propose a natural way to test for intrinsic value: first, strip the candidate bare of all considerations of good consequences; and, second, see if what remains is still a good thing. I argue that we, as ordinary human beings, have (...) an astonishingly difficult time completing this test for plausible candidates. More precisely, for us as we are, it seems that the conditions for completing the first step of the test militate against the conditions for completing the second step. I conclude, then, that we have a good reason to think that we cannot verify whether or not particular things are intrinsically good. I explore some implications and I consider a number of important objections. (shrink)

The incomparability of alternatives is thought to pose a problem for justified choice, particularly for proponents of comparativism – the view that comparative facts about alternatives determine what one rationally ought to choose. As a solution, it has been argued that alternatives judged incomparable by one of the three standard comparative relations, “better than,” “worse than,” and “equally good,” are comparable by some fourth relation, such as “roughly equal” or “on a par.” This solution, however, comes at what many would (...) regard as too high a cost – namely, rejection of the transitivity of the relation “at least as good as.” In this paper, I argue that proponents of comparativism need not incur this cost. I defend the possibility of justified choice between incomparable alternatives on grounds that comparativists can accept. The possibility of incomparability has been met with resistance, in part because of the intuitive appeal of comparativism. By defending the possibility of justified choice between incomparable alternatives on grounds that comparativists can accept, this paper supports further inquiry into the subject of incomparability.

This encyclopedia entry urges what it takes to be correctives to common (mis)understandings concerning the phenomenon of incommensurability and incomparability and briefly outlines some of their philosophical upshots.

In Rabinowicz 2008, I considered how value relations can best be analyzed in terms of fitting pro-­‐attitudes. In the formal model presented in that paper fitting pro-­‐attitudes are represented by the class of permissible preference orderings on a domain of items that are being compared. As it turns out, this approach opens up for a multiplicity of different types of value relationships, along with the standard relations of "better", "worse", "equally as good as" and "incomparable in value". Unfortunately, though, the (...) approach is vulnerable to a number of objections. I believe these objections can be avoided if one re-interprets the underlying notion of preference: Instead of treating preference as a 'dyadic' attitude directed towards a pair of items, we can think of it as a difference of degree between 'monadic' attitudes of favouring. Each such monadic attitude has just one item as its object. Given this re-interpretation, permissible preferences can be modelled by the class of permissible assignments of degrees of favouring to items in the domain. From this construction, we can then recover the old modelling in terms of the class of permissible preference orderings, but the previous objections to that model no longer apply. Thus, what we get is the old wine in new and hopefully tighter barrels. (shrink)

During his lifetime, F.C.S. Schiller was viewed as a major figure in the pragmatist movement, but his reputation has faded. This article will challenge the view that he was an unoriginal or less important figure. In particular, I will attempt a reconstruction of Schiller’s position on first philosophy, which will examine the differences between Schiller and the other major figures in the pragmatist movement. By using texts from Schiller’s writings, I attempt to create an undistorted reconstruction of what he wrote (...) in order to support this interpretation. I outline the implicit system contained in Schiller’s scattered writings and briefly examine the relation between Schiller’s humanism and other forms of pragmatism. The task seems both justified and worthwhile, since his work has been neglected, despite his prominence in the debates over pragmatism that took place when it emerged at the beginning of the twentieth century.

Value is either additive or else it is subject to organic unity. In general we have organic unity where a complex whole is not simply the sum of its parts. Value exhibits organic unity if the value of a complex, whether a complex state or complex quality, is greater or less than the sum of the values of its components or parts. Whether or not value is additive might be thought to be of purely metaphysical interest, but it is also (...) connected with important aspects of evaluative reasoning. Additivity is closely connected with principles of bare difference and separability which are often tacitly assumed in value theory. The author spells out these principles and trace their connections with additivity and organic unity. The author then develops an unpleasant paradox of additivity. Additivity apparently entails nihilism: that nothing is more valuable than anything else. Additivity involves a kind of axiological atomism -- that complexes decompose into components or factors; that these factors possess value independently of their role in valuable complexes; and that the factors do not interact in their production of overall value. In order to avoid the paradox it seems as though the factors have to be akin to the metaphysically privileged states of logical atomism -- a doctrine that does not enjoy widespread support. The paradox poses a problem not only for the notions of organic unity and additivity, but also for the closely related bare-difference principles which lie at the heart of value theory and of its application. The author proposes a way of eliminating the paradox, and thereby saving additivity and separability, without presupposing an unpalatable variant of logical atomism. The author closes with the proposal to treat principles of additivity as regulative ideals in our search for intrinsic values. (shrink)

Derek Parfit’s mere addition paradox has generated a large literature. This paper articulates one response to this paradox - which Parfit hirnself suggested - in terms of a formal account of the relation of parity. I term this response the ‘parity view’. It is consistent with transitivity of ‘at least as good as’, but implies incompleteness of this relation. The parity view is compatible with critical-band utilitarianism if this is adjusted to allow for vagueness. John Broome argues against accounts which (...) involve incompleteness. He thinks they are based on an intuition of ‘neutrality’, which is most naturally understood in terms of equality. There is no rationale, on Broome’s view, for seeing it as ‘incommensurateness’ which leads to incompleteness. Parity provides one. Broome’s worries that ‘incommensurateness’ makes neutrality implausibly ‘greedy’, and that ‘incommensurateness’ and vagueness are incompatible do not constitute a knock-down case against the parity view. Similar worries arise for his preferred vagueness view. (shrink)

This chapter presents an alternative to the standard view that at least some of the evaluations that the so-called “thick” terms and concepts in ethics may be used to convey belong to their sense or semantic meaning. After introducing the topic and making some methodological remarks, the chapter presents a wide variety of linguistic data that are well explained by the alternative view that at least a very wide range of thick terms and concepts are such that even the evaluations (...) that are most closely connected to them are only a certain kind of defeasible implications of their utterances which can be given a conversational explanation. The chapter then describes some reasons to think that this explanation of the data presented is superior to the standard view, although a fuller assessment must await further work. The chapter closes by explaining the largely deflationary consequences of this account for claims that thick terms and concepts have deep and distinctive significance to evaluative thought and judgment.

This chapter examines how social- scientific research on public preferences bears on the ethical question of how those resources should in fact be allocated, and explain how social-scientific researchers might find an understanding of work in ethics useful as they design mechanisms for data collection and analysis. I proceed by first distinguishing the methodologies of social science and ethics. I then provide an overview of different approaches to the ethics of allocating scarce medical interventions, including an approach—the complete lives system—which (...) I have previously defended, and a brief recap of social-scientific research on the allocation of scarce medical resources. Following these overviews, I examine different ways in which public preferences could matter to the ethics of allocation. Last, I suggest some ways in which social scientists could learn from ethics as they conduct research into public preferences regarding the allocation of scarce medical resources. (shrink)

Evaluative terms and concepts are often divided into “thin” and “thick”. We don’t evaluate actions and persons merely as good or bad, or right or wrong, but also as kind, courageous, tactful, selfish, boorish, and cruel. The latter evaluative concepts are "descriptively thick": their application somehow involves both evaluation and a substantial amount of non-evaluative description. This article surveys various attempts to answer four fundamental questions about thick terms and concepts. (1) A “combination question”: how exactly do thick terms and (...) concepts relate evaluation and non-evaluative description? (2) A “location question”: is evaluation somehow inherent to thick terms and concepts, such as perhaps an aspect of their meaning, or merely a feature of their use? (3) A “delineation question”: how do thick terms differ from the thin and from other kinds of evaluative terms? (4) Given answers to these questions, what broader philosophical significance and applications might thick concepts have? (shrink)

This Note offers a normative critique of cost-benefit analysis, one informed by deontological moral theory, in the context of the debate over whether tort litigation or a non-tort approach is the appropriate response to mass harm. The first Part argues that the difference between lay and expert intuitions about risk and harm often reflects a difference in normative judgments about the existing facts, rather than a difference in belief about what facts exist, which makes the lay intuitions more defensible. The (...) second Part considers how tort has dealt with this divergence between lay and expert perspectives. It also evaluates how tort's approach has differed from that of public law approaches to accident law, such as legislative compensation and risk regulation by administrative agencies. Ultimately, tort's ability to recognize the value of lay intuitions supports retaining the tort perspective as part of our societal arsenal of responses to risk and harm. This ability can also support a pro-tort perspective in two practical debates in the arena of tort law: that over preemption of tort law by administrative agency judgments, and that over access to tort recovery as part of a no-fault system.

Are values objective or subjective? To clarify this question we start with an overview of the main concepts and debates in the philosophy of values. We then discuss the arguments for and against value realism, the thesis that there are objective evaluative facts. By contrast with value anti-realism, which is generally associated with sentimentalism, according to which evaluative judgements are grounded in sentiments, value realism is commonly coupled with rationalism. Against this common view, we argue that value realism can be (...) combined with sentimentalism, and we suggest that a plausible account, which we call ‘sentimental realism’, and according to which evaluative judgements are closely related to emotions, can be developped. (shrink)

In addition to thin concepts like the good, the bad and the ugly, our evaluative thought and talk appeals to thick concepts like the lewd and the rude, the selfish and the cruel, the courageous and the kind -- concepts that somehow combine evaluation and non-evaluative description. Thick concepts are almost universally assumed to be inherently evaluative in content, and many philosophers claimed them to have deep and distinctive significance in ethics and metaethics. In this first book-length treatment of thick (...) concepts, Pekka Väyrynen argues that all this is mistaken. Through detailed attention to the language of thick concepts, he defends a novel theory on which the relationship between thick words and evaluation is best explained by general conversational and pragmatic norms. Drawing on general principles in philosophy of language, he argues that many prominent features of thick words and concepts can be explained by general factors that have nothing in particular to do with being evaluative. If evaluation is not essential to the sort of thinking we do with thick concepts, claims for the deep and distinctive significance of the thick are undermined. The Lewd, the Rude and the Nasty is a fresh and innovative treatment of an important topic in moral philosophy and sets a new agenda for future work. It will be essential reading to anyone interested in the analysis and the broader philosophical significance of evaluative and normative language. (shrink)

The discovery of so-called ‘mirror neurons’ - found to respond both to own actions and the observation of similar actions performed by others - has been enormously influential in the cognitive sciences and beyond. Given the self-other symmetry these neurons have been hypothesized as underlying a ‘mirror mechanism’ that lets us share representations and thereby ground core social cognitive functions from intention understanding to linguistic abilities and empathy. I argue that mirror neurons are important for very different reasons. Rather than (...) a symmetric ubiquitous or context- independent mechanism, I propose that these neurons are part of broader sensorimotor circuits, which help us navigate and predict the social affordance space that we meet others in. To develop both the critical and positive project I analyze the interpretive choices and the debate surrounding the mirror neuron research and show how the field is marred by highly questionable assumptions about respectively motor and social cognition. The discovery of mirror neurons - and the sensorimotor circuits of which these neurons are a part – actually empirically challenge many of these tacit assumptions. Findings of sensorimotor goal representations at levels of abstraction well beyond actual sensory information and kinetic movements challenge the idea of motor cognition as primarily output production. Additionally, the focus on 3rd person mindreading of hidden mental states is misguiding the field of social cognition. Much ‘mind-reading’ seems rooted in sensorimotor representations and a developmentally primary 2nd person understanding of actions and the mental lives of others, which precisely breaks the assumed dichotomy between mind and behavior. I propose a Social Affordance model where parallel fronto-parietal sensorimotor circuits support representations not just of other people’s actions but of the overall social affordance space. It is a process that monitors concrete goals and teleological possibilities that the environment affords respectively oneself and other present agents. With this model I hypothesize that the complex spectrum of sensorimotor integrations are indeed essential not only to normal action choice calibration but also to social cognitive abilities, as the sensorimotor teleological representations let us relate to others and understand their action choices in a shared pragmatic and intentional context.

Many philosophers believe that the extensions of evaluative terms and concepts aren’t unified under non-evaluative similarity relations and that this “shapelessness thesis” (ST) has significant metaethical implications regarding non-cognitivism, ethical naturalism, moral particularism, thick concepts and more. ST is typically offered as an explanation of why evaluative classifications appear to “outrun” classifications specifiable in independently intelligible non-evaluative terms. This paper argues that both ST and the outrunning point used to motivate it can be explained on the basis of more general (...) factors that have nothing in particular to do with being evaluative. If so, there is no reason to expect ST to carry the sorts of metaethical implications that get attributed to it. I also show that my main argument is robust across certain complications that are raised by the context-sensitivity of many evaluative terms but have so far been ignored in discussions of ST and related matters.

For a while in this article it seems impossible to articulate a compelling reason for refraining from killing an innocent stranger with the press of a button when this would earn one a small prize and would be done with absolutely guaranteed immunity from any punishment or other harm (including even an instantaneous elimination of any chance of a guilty memory, achieved through hypnosis, and an ironclad commitment from God not to condemn the killing). After many failed attempts, a compelling (...) reason for not pushing the button is finally articulated. A distinction is demonstrated between merely apparent, mistaken desires and real desires. One might, for example, have merely an apparent, mistaken desire to be drinking the stuff in a mug of hot mud if one mistakenly believed that the stuff was hot chocolate. One would not really desire to be drinking that stuff. A desire, which must always be based on some belief about what its object is like, would always be open to correction along with the belief on which it depended. This realisation leads to the sweeping principle that one can only really desire what one would be desiring with a hypothetical perfect grasp of all that is involved. If one desires something only because of not fully grasping what that thing is, then one does not really desire it. What one really desires, then, regarding this stranger and pushing the button has to be what one would desire if fully experiencing, among other things, the entire value of the stranger's life from his own as well as every other angle along with the small value for oneself of the prize received on killing him. This equal concern for all is morality, and what is compelling in morality is that what it commands is what everyone really desires. (shrink)

This article deals with how to talk about the political. After the introduction (I), I show, first, that Putnam’s arguments against the root dichotomies between facts and values (II), and between values and norms (III), are valid. I then discuss Putnam’s resistance to drawing skeptical lessons from these negative arguments, a fight that is largely successful (IV). I go on to sketch his own middle position, looking at the way he expands cognitive meaning in the practical sphere (V). I end (...) by addressing Putnam’s specific stance towards the political, arguing here that a relative distinction between facts, values and norms allows us to speak about the political both in a more direct and a balanced way. This means reopening the case of representation (VI). (shrink)

This article aims to clarify the view that thick concepts are irreducibly thick. I do this by putting the disentangling argument in its place and then setting out what nonreductivists about the thick are committed to. To distinguish the view from possible reductive accounts, defenders of irreducible thickness are, I argue, committed to the claim that evaluative concepts and properties are nonevaluatively shapeless. This in turn requires a commitment to (radical) holism and particularism. Nonreductivists are also committed to the claim (...) that a thick concept is in itself evaluative, and not evaluative because of any link to thin evaluation. (shrink)

In this paper, I want to discuss the recent attempts by Professor John R. Searle to cast doubt on the traditional empiricist distinction between fact and value. Searle's first attack on this distinction was made in 1964 in his now classic article, “How to derive ‘ought’ from ‘is’.” In that paper, he presented what he claimed to be a counter-example to the thesis that statements of fact may not entail statements of value. Searle's argument aroused much controversy and inspired many (...) attempted refutations, but Searle apparently found none of these convincing, for a few years later he published a revised version of his paper as the last chapter of his book, Speech Acts. The new version includes his replies to many of the objections which had been made to his thesis up to that time. It also includes, in the main body of the book, a theory of language which is supposed to provide the theoretical underpinning explaining why his original paper presents a genuine counter-example to the position he is attacking. It is the Speech Acts version of Searle's thesis which I want to consider here. (shrink)

Towards the end of their reign, the logical positivists found themselves in bitter disagreement as to what extent the methods and axioms of the natural sciences can be justified by our abilities to grunt and point. What began as a project to epistemically ground the natural sciences ended as an argument about cavemen. Although such a story might be a good one, the consensus, among the positivists’ rivals and the positivists themselves, seemed to be that ahead lay a difficult road (...) indeed if grunts clarify physics. Understandably, that road would be one not traveled, and so our weary fact-warriors walked off elsewhere, leaving the detritus in their path and the rest of the world to deal with the consequences. And consequences there were. Take the current, popular idea that the natural sciences need not be governed by moral concerns; or if they do, such moral governance only need be justified by appeals to governmental, technological or, happily in this most learned of eras, divine authority. Although we may not be able to connect such popular ideas directly to the positivist program, it is nevertheless no great leap to say that their program was motivated in strong ways by a blind acceptance of the abilities of technological advancement and the triumphant march of the natural sciences.

If I desire to drink some stuff thinking it is hot chocolate when actually it is hot mud, my desire is not a real one - it’s mistaken or only apparent. This example illustrates how a desire must always depend on a belief about its object, a belief about what it is and what it’s like. But beliefs are correctable, so desires are correctable. This leads us directly to a very sweeping principle - that I only really desire what I (...) would be desiring with a perfect grasp of everything involved. If there’s something that I desire only because my grasp of it is less than perfect, then it is not something that I really desire. I have no real reason for wanting it, and it would not be in my real self-interest to get it. The hypothetical perfect grasp that defines a real desire would have to have a God-like reach into all the relevant realities in all their actuality and all their potential. And it would have to include perfectly within it all the desires of all those affected by what the grasp was of. Therefore what would be wanted in a perfect grasp would be a reconciliation of all the systems of desire contained within it - not as they happen to be but as they would be corrected by a perfect grasp. This reconciliation of systems of desire is that which morality requires. Therefore what I really want - my own fully-corrected self-interest - is precisely the same as the requirements of morality. This sameness explains and justifies morality’s categorical character and over-riding authority. (shrink)

Though modern non-cognitivists in ethics characteristically believe that values are irreducible to facts, they nevertheless believe that values are determined by facts, viz., those specified in functionalist, explanatory theories of the evolutionary origin of morality. The present paper probes the consistency of this position. The conventionalist theories of Hume and Harman are examined, and are seen not to establish a tight determinative reduction of values to facts. This result is illustrated by reference to recent theories of the sociobiological mechanisms involved (...) in moral evolution. Though explanatory theories have linguistic implications,exaggerated in Harman's linguistic form of social relativism, there is also failure to establish the semantic reductionism which non-cognitivists reject under the rubric of ethical naturalism. It is concluded that explanatory forms of naturalism, the best of which is a functionalist-utilitarian account, are compatible with the fact/value distinction. (shrink)

By what types of properties do we specify twinges, toothaches, and other kinds of mental states? Wittgenstein considers two methods. Procedure one, direct, private acquaintance: A person connects a word to the sensation it specifies through noticing what that sensation is like in his own experience. Procedure two, outward signs: A person pins his use of a word to outward, pre-verbal signs of the sensation. I identify and explain a third procedure and show we in fact specify many kinds of (...) mental states in this way. (shrink)

According to a famous maxim, ignorance or mistake of law is no excuse. This maxim is supposed to represent both the standard and the proper rule of law. In fact, this maxim should be qualified in both respects: ignorance and mistake of law sometimes are, and (perhaps even more often) should be, excused. But this dual qualification only reinforces the fundamental and ubiquitous assumption which underlies the discussions of the subject, namely, that the only ground of exculpation relevant to ignorance (...) or mistake of law is excuse due to lack of (sufficient) culpability. The paper challenges this consensus. I argue that, according to the best conception of justification, ignorance and mistake, including ignorance and mistake of law, could be justified. Generally, ignorance and mistake are justified when based on a rational analysis of the information the agent has and should have. The conceptual possibility of justified ignorance or mistake is demonstrated mainly with respect to ignorance or mistake of law due to reliance on the guidance of public officials or private lawyers.

This article is a defence of the Fact-Value distinction against considerations brought up by Ruth Anna Putnam in three articles in Philosophy, especially her ‘Perceiving Facts and Values’ January 1998. I defend metaphysical realism about facts and anti-realism about values against Putnam' intermediate position about both and I relate the matter to the logic of imperatives. The motivations of scientists or historians to select fields of investigation are irrelevant to the objectivity of their hypotheses, and so is the goodness or (...) badness of the social consequences of their work though these may affect their motivations.

Sometimes, when comparing a pair of items, it appears that neither is better than the other, nor that they are equally good, relative to a certain value that they bear. Cases of this kind have come to be referred to as superhard comparisons. What grounds superhard comparisons? On the dominant views, held by Joseph Raz and Ruth Chang, they are grounded, at least partially, in the failure of the three classic value relations—‘better than’, ‘worse than’, and ‘equally good’. On an (...) alternative view, which might be called the vagueness view, first developed by John Broome, they are grounded in vagueness about which of the classic value relations holds between the items. In this paper, I pay special attention to superhard comparisons in the context of choice and develop a novel argument against the dominant views on the basis of an account of decision-making under vagueness in ‘better than’. The upshot is that a new vagueness view emerges. (shrink)

According to asymmetric comparativism, it is worse for a person to exist with a miserable life than not to exist, but it is not better for a person to exist with a happy life than not to exist. My aim in this paper is to explain how asymmetric comparativism could possibly be true. My account of asymmetric comparativism begins with a different asymmetry, regarding the (dis)value of early death. I offer an account of this early death asymmetry, appealing to the (...) idea of conditional goods, and generalize it to explain how asymmetric comparativism could possibly be true. I also address the objection that asymmetric comparativism has unacceptably antinatalist implications. (shrink)

Totalism is the view that one distribution of well-being is better than another just in case the one contains a greater sum of well-being than the other. Many philosophers, following Parfit, reject totalism on the grounds that it entails the repugnant conclusion that, for any number of excellent lives, there is some number of mediocre lives whose existence would be better. This paper develops a theory of welfare aggregation—the lexical-threshold view—that allows totalism to avoid the repugnant conclusion, as well as (...) its analogues involving suffering populations and the lengths of individual lives. The theory is grounded in some independently plausible views about the structure of well- being, identifies a new source of incommensurability in population ethics, and avoids some of the implausibly extreme consequences of other lexical views, without violating the intuitive separability of lives.

We give two social aggregation theorems under conditions of risk, one for constant population cases, the other an extension to variable populations. Intra and interpersonal welfare comparisons are encoded in a single ‘individual preorder’. The theorems give axioms that uniquely determine a social preorder in terms of this individual preorder. The social preorders described by these theorems have features that may be considered characteristic of Harsanyi-style utilitarianism, such as indifference to ex ante and ex post equality. However, the theorems are (...) also consistent with the rejection of all of the expected utility axioms, completeness, continuity, and independence, at both the individual and social levels. In that sense, expected utility is inessential to Harsanyi-style utilitarianism. In fact, the variable population theorem imposes only a mild constraint on the individual preorder, while the constant population theorem imposes no constraint at all. We then derive further results under the assumption of our basic axioms. First, the individual preorder satisfies the main expected utility axiom of strong independence if and only if the social preorder has a vector-valued expected total utility representation, covering Harsanyi’s utilitarian theorem as a special case. Second, stronger utilitarian-friendly assumptions, like Pareto or strong separability, are essentially equivalent to strong independence. Third, if the individual preorder satisfies a ‘local expected utility’ condition popular in non-expected utility theory, then the social preorder has a ‘local expected total utility’ representation. Fourth, a wide range of non-expected utility theories nevertheless lead to social preorders of outcomes that have been seen as canonically egalitarian, such as rank-dependent social preorders. Although our aggregation theorems are stated under conditions of risk, they are valid in more general frameworks for representing uncertainty or ambiguity. (shrink)

We generalize Harsanyi's social aggregation theorem. We allow the population to be infi nite, and merely assume that individual and social preferences are given by strongly independent preorders on a convex set of arbitrary dimension. Thus we assume neither completeness nor any form of continuity. Under Pareto indifference, the conclusion of Harsanyi's theorem nevertheless holds almost entirely unchanged when utility values are taken to be vectors in a product of lexicographic function spaces. The addition of weak or strong Pareto has (...) essentially the same implications in the general case as it does in Harsanyi's original setting. (shrink)

Supererogatory acts—good deeds “beyond the call of duty”—are a part of moral common sense, but conceptually puzzling. I propose a unified solution to three of the most infamous puzzles: the classic Paradox of Supererogation (if it’s so good, why isn’t it just obligatory?), Horton’s All or Nothing Problem, and Kamm’s Intransitivity Paradox. I conclude that supererogation makes sense if, and only if, the grounds of rightness are multi-dimensional and comparative.

According to the person-affecting restriction, one distribution of welfare can be better than another only if there is someone for whom it is better. Extant problems for the person-affecting restriction involve variable-population cases, such as the nonidentity problem, which are notoriously controversial and difficult to resolve. This paper develops a fixed-population problem for the person-affecting restriction. The problem reveals that, in the presence of incommensurable welfare levels, the person-affecting restriction is incompatible with minimal requirements of impartial beneficence even in fixed-population (...) contexts.

If A is better than B and B is better than C, then A is better than C, right? Larry Temkin and Stuart Rachels say: No! Betterness is nontransitive, they claim. In this paper, I discuss the central type of argument advanced by Temkin and Rachels for this radical idea, and argue that, given this view very likely has sceptical implications for practical reason, we would do well to identify alternative responses. I propose one such response, which employs the idea (...) that rational agents might regard some options as incommensurate in value, and will reasonably employ a heuristic of status quo maintenance to avoid suboptimal choices from incommensurate goods. (shrink)

I argue that any plausible decision theory for agents with incomplete preferences which obeys the Never Worse Principle will violate Transitivity. The Never Worse Principle says that if one option never does worse than another, you shouldn’t disprefer it. Transitivity says that if you prefer X to Y and you prefer Y to Z, then you should prefer X to Z. Violating Transitivity allows one to be money pumped. Although agents with incomplete preferences are already, in virtue of having incomplete (...) preferences, vulnerable to being money pumped, I argue that the money pump argument for Transitivity is more serious than the one for Completeness.

Let’s say that you regard two things as on a par when you don’t prefer one to other and aren’t indifferent between them. What does rationality require of you when choosing between risky options whose outcomes you regard as on a par? According to Prospectism, you are required to choose the option with the best prospects, where an option’s prospects is a probability-distribution over its potential outcomes. In this paper, I argue that Prospectism violates a dominance principle—which I call The (...) Principle of Predominance—because it sometimes requires you to do something that’s no better than the alternatives and might be worse. I argue that this undermines the strongest argument that’s been given in favor of Prospectism. (shrink)
