In this paper we offer a response to one argument in favour of Priority Monism, what Jonathan Schaffer calls the nomic argument for monism. We proceed in three stages. We begin by introducing Jonathan Schaffer’s Priority Monism and the nomic argument for that view. We then consider a response to the nomic argument that we presented in an earlier paper. We show that this argument suffers from a flaw. We then go on to offer a different response to (...) the nomic argument. The core idea is that the current laws of physics are not integrated in the manner that Schaffer requires to get the nomic argument for monism off the ground. (shrink)

In folk psychology and some academic psychology, utilitarian thinking is associated with coldness and deontological thinking is associated with emotion. I suggest, mostly through personal examples, that these associations are far from perfect. Utilitarians experience emotions, which sometimes derive from, and sometimes cause or reinforce, their moral judgments.

What is intelligence? Can it be increased by teaching? If so, how, and what difference would an increase make? Before we can answer these questions, we need to clarify them. Jonathan Baron argues that when we do so we find that intelligence has much to do with rational thinking, and that the skills involved in rational thinking are in fact teachable, at least to some extent. Rationality and Intelligence develops and justifies a prescriptive theory of rational thinking in (...) terms of utility theory and the theory of rational life plans. The prescriptive theory, buttressed by other assumptions, suggests that people generally think too little and in a way that is insufficiently critical of the initial possibilities that occur to them. However these biases can be - and sometimes are - corrected by education. (shrink)

The fifth edition of the classic text Thinking and Deciding updates the broad overview of the field of judgments and decisions offered in previous editions. It covers the normative standards used to evaluate conclusions, such as logic, probability, and various forms of utility theory. It explains descriptive accounts of departures from these standards, largely in terms of principles of cognitive psychology, emphasizing the distinction between search processes and inferences. Chapters cover decisions under risk, decision analysis, moral decisions and social dilemmas, (...) and decisions about the future. Although the book assumes no particular prerequisites beyond introductory high-school algebra, it is most suited to advanced undergraduates, early graduate students, and active researchers in related fields, such as business, politics, law, medicine, economics, and philosophy. -/- .

Argues that applied bioethics should embrace utilitarian decision analysis, thus avoiding recommendations expected to do more harm than good. -/- Governments, health professionals, patients, research institutions, and research subjects look to bioethicists for guidance in making important decisions about medical treatment and research. And yet, argues Jonathan Baron in Against Bioethics, applied bioethics lacks the authority of a coherent guiding theory and is based largely on intuitive judgments. Baron proposes an alternative, arguing that bioethics could have a (...) coherent theory based on utilitarianism and decision analysis. Utilitarianism holds that the best option is the one that does the most expected good. Decision analysis provides a way of thinking about the risks and trade-offs of specific options. Like economics, utilitarian decision analysis makes predictions of expected good in complex situations, using data when possible, and focusing human judgment on the issues relevant to consequences. With such a guiding theory, bioethics would never yield decisions that clearly go against the expected good of those involved, as some do now. -/- Baron discusses issues in bioethics that can be illuminated by such analysis, including "enhancements" to nature in the form of genetics, drugs, and mind control; reproduction; death and end-of-life issues, including advance directives, euthanasia, and organ donation; coercion and consent; conflict of interest and the reform of internal review boards; and drug research. Although Baron opposes current practice in bioethics, he argues that by combining utilitarianism and decision analysis, bioethics can achieve its aims of providing authoritative guidance in resolving thorny medical and ethical issues.

Richard M. Hare (1919 - 2002) is usually acknowledged to be one of the major moral thinkers of the 20th century. After being a Japanese prisoner of war for most of World War II, he completed his education at Oxford, later joining the faculty and becoming a professor. In 1983 he moved to the University of Florida but still kept his ties with Oxford. He had many students, including Peter Singer. At a memorial service for Hare in 2002, Singer ascribed (...) to him three major achievements in moral philosophy, namely “restoring reason to moral argument, distinguishing intuitive and critical levels of moral thinking, and pioneering the development of practical or applied ethics”.

In this article, I shall suggest an approach to the justification of normative moral principles which leads, I think, to utilitarianism. The approach is based on asking what moral norms we would each endorse if we had no prior moral commitments. I argue that we would endorse norms that lead to the satisfaction of all our nonmoral values or goals. The same approach leads to a view of utility as consisting of those goals that we would want satisfied. In the (...) second half of the article, I examine the implication of this view for several issues about the nature of utility, such as the use of past and future goals. The argument for utilitarianism is not completed here. The rest of it requires a defense of expected-utility theory, of interpersonal comparison, and of equal consideration. (shrink)

Considerable evidence supports the sequential two-system model of moral judgement, as proposed by Greene and others. We tested whether judgement speed and/or personal/impersonal moral dilemmas can predict the kind of moral judgements subjects make for each dilemma, and whether personal dilemmas create difficulty in moral judgements. Our results showed that neither personal/impersonal conditions nor spontaneous/thoughtful-reflection conditions were reliable predictors of utilitarian or deontological moral judgements. Yet, we found support for an alternative view, in which, when the two types of responses (...) are in conflict; the resolution of this conflict depends on both the subject and the dilemma. While thinking about this conflict, subjects sometimes change their minds in both directions, as suggested by the data from a mouse-tracking task. (shrink)

What distinguishes causation from grounding? One suggestion is that causation, but not grounding, occurs over time. Recently, however, counterexamples to this simple temporal criterion have been offered. In this paper, we situate the temporal criterion within a broader framework that focuses on two aspects: locational overlapping in space and time and the presence of intermediaries in space and time. We consider, and reject, the idea that the difference between grounding and causation is that grounding can occur without intermediaries. We go (...) on to use the fact that grounding and causation both involve intermediaries to develop a better temporal criterion for distinguishing causation from grounding. The criterion is this: when a cause and effect are spatially disjoint, there is always a chain of causal intermediaries between the cause and the effect that are extended in time. By contrast, when the grounds and the grounded are spatially disjoint, there is always a chain of grounding intermediaries, but the chain need not be extended in time, it can be purely spatial. The difference between grounding and causation, then, is that causation requires time for chaining in a way that grounding does not. (shrink)

According to a simple form of consequentialism, we should base decisions on our judgments about their consequences for achieving our goals. Our goals give us reason to endorse consequentialism as a standard of decision making. Alternative standards invariably lead to consequences that are less good in this sense. Yet some people knowingly follow decision rules that violate consequentialism. For example, they prefer harmful omissions to less harmful acts, they favor the status quo over alternatives they would otherwise judge to be (...) belter, they provide third-party compensation on the basis of the cause of an injury rather than the benefit from the compensation, they ignore deterrent effects in decisions about punishment, and they resist coercive reforms they judge to be beneficial. I suggest that nonconsequentialist principles arise from overgeneralizing rules that are consistent with consequentialism in a limited set of cases. Commitment to such rules is detached from their original purposes. The existence of such nonconsequentialist decision biases has implications for philosophical and experimental methodology, the relation between psychology and public policy, and education. (shrink)

Priority monism (hereafter, ‘monism’) is the view that there exists one fundamental entity—the world—and that all other objects that exist (a set of objects typically taken to include tables, chairs, and the whole menagerie of everyday items) are merely derivative. Jonathan Schaffer has defended monism in its current guise, across a range of papers. Each paper looks to add something to the monistic picture of the world. In this paper we argue that monism—as Schaffer describes it—is false. To do (...) so we develop an ‘island universe’ argument against Schaffer's monistic theory. (shrink)

Ockham's razor asks that we not multiply entities beyond necessity. The razor is a powerful methodological tool, enabling us to articulate reasons for preferring one theory to another. There are those, however, who would modify the razor. Schaffer, for one, tells us that, ‘I think the proper rendering of Ockham's razor should be ‘Do not multiply fundamental entities without necessity’’. Our aim, here, is to challenge such re-workings of Ockham's razor.

Background: Some members of the general public feel that patients who cause their own organ failure through smoking, alcohol use, or drug use should not receive equal priority for scarce transplantable organs. This may reflect a belief that these patients (1) cause their own illness, (2) have poor transplant prognoses or, (3) are simply unworthy. We explore the role that social acceptability, personal responsibility, and prognosis play in people's judgments about transplant allocation. Methods: By random allocation, we presented 283 prospective (...) jurors in Philadelphia county with one of five questionnaire versions. In all questionnaires, subjects were asked to distribute transplantable hearts between patients with and without a history of three controversial behaviors (eating high fat diets against doctors’ advice, cigarette smoking, or intravenous drug use). Across the five questionnaire versions, we varied the relative prognosis of the transplant candidates and whether their behavior caused their primary organ Results: Subjects were significantly less willing to distribute organs to intravenous drug users than to cigarette smokers or people eating high fat diets (p le; 0.0005), even when intravenous drug users had better transplant outcomes than other patients. Subjects’ allocation decisions were influenced by transplant prognosis, but not by whether the behavior in question was causally responsible for the patients’ organ failure. Conclusion: People's unwillingness to give scarce transplantable organs to patients with controversial behaviors cannot be explained totally on the basis of those behaviors either causing their primary organ failure or making them have worse transplant prognoses. Instead, many people believe that such patients are simply less worthy of scarce transplantable organs. (shrink)

In this paper, we explore locative grounding harmony, according to which the location of the grounds mirrors the location of the grounded. We proceed in three stages. First, we clarify the notion of locative harmony and describe different locative harmony principles. Second, we offer two arguments for the claim that grounding between physically located entities obeys principles of locative harmony. Third, we consider and respond to a range of cases that seem to show that grounding relations between physically located entities (...) do not obey such principles. We conclude that grounding between such entities obeys locative harmony. (shrink)

Current debate in the metaphysics of time ordinarily assumes that we should be realists about time. Recently, however, a number of physicists and philosophers of physics have proposed that time will play no role in a completed theory of quantum gravity. This paper defends fictionalism about temporal thought, on the supposition that our world is timeless. We argue that, in the face of timeless physical theories, realism about temporal thought is unsustainable: some kind of anti-realism must be adopted. We go (...) on to provide an argument against eliminativism about temporal thought. While it doesn't follow from this argument that fictionalism about temporal thought is true, we suggest that this nonetheless shows that fictionalism should be regarded as the preferred view.

The principle of exchange seems to be limited in its application, and it cannot serve as a link between utilitarianism and the idea of a market for interpersonal relations. Our preferences concern the inner states of other people as well as their overt behavior. The neglect of this aspect of our preferences is a result of the coupling of utilitarianism with behaviorism. The problem is thus behaviorism, not consequentialism. It might be argued that commensurability is wrong because it sanctions impure (...) practices - aside from any principle of exchange. In reply, it may be argued that the principle of purity is an intuitive one, which must be justified at a higher level. At the intuitive level, the purity principle competes with the view that practices are in some cases too pure already, and that blind purity cannot be maintained without educational deception. The apparent difficulty of making tradeoffs among different kinds of consequences is a problem in practice, not a problem in principle. The difficulty may indeed justify certain prescriptive rules, but a blanket prohibition against impure practices would seem to require considerable defense. (shrink)

College-student subjects made notes about the morality of early abortion, as if they were preparing for a class discussion. Analysis of the quality of their arguments suggests that a distinction can be made between arguments based on well-supported warrants and those based on warrants that are easily criticised. The subjects also evaluated notes made by other, hypothetical, students preparing for the same discussion. Most subjects evaluated the set of arguments as better when the arguments were all on one side than (...) when both sides were presented, even when the hypothetical student was on the opposite side of the issue from the evaluator. Subjects who favoured one-sidedness also tended to make one-sided arguments themselves. The results suggest that ?myside bias? is partly caused by beliefs about what makes thinking good. (shrink)

The Triviality Argument against presentism maintains that we should reject presentism because there is no way to define the view that is not either trivially true or obviously false. We suggest that this style of argument over-emphasises purely linguistic means of representing a philosophical thesis. We argue that there is no reason to suppose that all philosophical theses must be linguistically representable, and thus that the failure to linguistically represent presentism is no big deal. It certainly shouldn’t lead us to (...) reject the view. We offer a more general moral for philosophy, and that is to look beyond purely linguistic methods of representing philosophical views and embrace a wider range of representational media. (shrink)

In four experiments, we asked subjects for judgements about scenarios that pit utilitarian outcomes against deontological moral rules, for example, saving more lives vs. a rule against active killing. We measured trait emotions of anger, disgust, sympathy and empathy, asked about the same emotions after each scenario. We found that utilitarian responding to the scenarios, and higher scores on a utilitarianism scale, were correlated negatively with disgust, positively with anger, positively with specific sympathy and state sympathy, and less so with (...) general sympathy or empathy. In a fifth experiment, we asked about anger and sympathy for specific outcomes, and we found that these are consistently predictive of utilitarian responding. (shrink)

When people tend toward a political decision, such as voting for the Republican Party, they are often attracted to this decision by one issue, such as the party’s stance on abortion, but then they come to see other issues, such as the party’s stand on taxes, as supporting their decision, even if they would not have thought so in the absence of the decision. I demonstrate this phenomenon with opinion poll data and with an experiment done on the World Wide (...) Web using hypothetical candidates. For the hypothetical candidates, judgments about whether a candidate’s position on issue A favors the candidate or the opponent are correlated with judgments about other positions taken by the candidate (as determined from other hypothetical candidates). This effect is greater in those subjects who rarely make conflicting judgments, in which one issue favors a candidate and another favors the opponent. In a few cases, judgments even reverse, so that a position that is counted as a minus for other candidates becomes a plus for a favored candidate. Reversals in the direction of a candidate’s position are more likely when the candidate is otherwise favored. The experiment provides a new kind of demonstration of “belief overkill,” the tendency to bring all arguments into line with a favored conclusion. (shrink)

A two-systems model of moral judgment proposed by Joshua Greene holds that deontological moral judgments (those based on simple rules concerning action) are often primary and intuitive, and these intuitive judgments must be overridden by reflection in order to yield utilitarian (consequence-based) responses. For example, one dilemma asks whether it is right to push a man onto a track in order to stop a trolley that is heading for five others. Those who favor pushing, the utilitarian response, usually take longer (...) to respond than those who oppose pushing. Greene's model assumes an asymmetry between the processes leading to different responses. We consider an alternative model based on the assumption of symmetric conflict between two response tendencies. By this model, moral dilemmas differ in the "difficulty" of giving a utilitarian response and subjects differ in the "ability" (tendency) to give such responses. (We could just as easily define ability in terms of deontological responses, as the model treats the responses symmetrically.) We thus make an analogy between moral dilemmas and tests of cognitive ability, and we apply the Rasch model, developed for the latter, to estimate the ability-difficulty difference for each dilemma for each subject. We apply this approach to five data sets collected for other purposes by three of the co-authors. Response time (RT), including yes and no responses, is longest when difficulty and ability match, because the subject is indifferent between the two responses, which also have the same RT at this point. When we consider yes/no responses, RT is longest when the model predicts that the response is improbable. Subjects with low ability take longer on the "easier" dilemmas, and vice versa. (shrink)

Self-interest voting is irrational when it has even a small cost, but it can be rational for those who care about others; its expected utility (EU) may exceed its cost. For cosmopolitan voters (those who care about outsiders), the EU of voting increases with the number of affected others. The EU of voting for the good of the world now and in the future can thus be large. In some cases, the EU of parochial voting (e.g., considering only one's nation) (...) may not cross the cost threshold, but cosmopolitan voting can cross it. I apply these principles to various kinds of voting. And I compare voting to charity. Voting has the advantage of enlisting the coercive power of the state, but charity can be more focused on effective policies. I discuss campaign contributions, and I conclude with a discussion of the existence of utilitarian voters. (shrink)

Mereological harmony is the idea that the mereological structure of objects mirrors the mereological structure of locations. Grounding harmony is the idea that there is a similar mirroring between the grounding structure of objects and locations. Our goal in this paper is exploratory: we introduce and then explore two notions of grounding harmony: locative and structural. We outline potential locative and structural harmony principles for grounding, and show which of these principles may entail, or be entailed by, principles of mereological (...) harmony. We then present a case study in grounding harmony, by applying it to Schaffer’s :31, 2010a) specific version of priority monism. We show that, given a strong form of grounding harmony, Schaffer-style monism is inconsistent, but that this inconsistency can be resolved by offering bespoke notions of grounding harmony. We use Schaffer’s priority monism to demonstrate a broader tension within certain packages of metaphysical views, including versions of priority pluralism. We close by briefly considering the case against structural grounding harmony. (shrink)

Protected values (PVs) are values protected from trade-offs with other values. They are absolute in this sense. People hold these values even when they do not necessarily abide by them in their behavior. I suggest that most of these values are a subset of deontological rules, defined by their absoluteness. Their origin may be understood by looking at the origin of deontological rules more generally, which includes religious (hence sacred) values among others. But PVs are usually maintained by lack of (...) reflection of the sort that would see counterexamples to their absoluteness. PVs often have other characteristics that would lead to classification into other types of values: they are often moralistic (imposed on others regardless of the willingness of others to accept them); they are about morality rather than convention and thus independent of authority or social consensus; and they often concern second-order preferences (values for values). Especially in combination with these other properties, PVs can be harmful in the domain of politics. Education in the sort of reflection that would lead people to question them could improve the political situation around the world. (shrink)

Previous research has discovered a curious phenomenon: groups cooperate less than individuals in a deterministic prisoner’s dilemma game, but cooperate more than individuals when uncertainty is introduced into the game. We conducted two studies to examine three possible processes that might drive groups to be more cooperative than individuals in reducing risks: group risk concern, group cooperation expectation, and pressure to conform to social norms. We found that ex post guilt aversion and ex-post blame avoidance cause group members to be (...) more risk concerned than individuals under uncertainty. These concerns drive groups to choose the cooperation (and risk-reduction) strategy more frequently than individuals. Groups also have higher cooperation expectations for their corresponding groups than individuals have for their corresponding individuals. We found no evidence of pressure to conform to social norms driving groups to be more cooperative than individuals. (shrink)

Cognitive biases that affect decision making may affect the decisions of citizens that influence public policy. To the extent that decisions follow principles other than maximizing utility for all, it is less likely that utility will be maximized, and the citizens will ultimately suffer the results. Here I outline some basic arguments concerning decisions by citizens, using voting as an example. I describe two types of values that may lead to sub-optimal consequences when these values influence political behavior: moralistic values (...) (which people are willing to impose on others regardless of the consequences) and protected values (PVs, values protected from trade-offs). I present evidence against the idea that voting is expressive, i.e., that voters aim to express their moral views rather than to have an effect on outcomes. I show experimentally that PVs are often moralistic. Finally, I present some data that citizens’ think of their duty in a parochial way, neglecting out-groups. I conclude that moral judgments are important determinants of citizen behavior, that these judgments are subject to biases and based on moralistic values, and that, therefore, outcomes are probably less good than they could be.

Integrative experiments, as described, seem blindly empirical, as if the question of generality of effects could not be understood through controlled one-at-a-time experiments. But current research using such experiments, especially applied research, can resolve issues and make progress through understanding of cause–effect pathways, leaving to engineers the task of translating this understanding into practice.

Stanovich & West (S&W) have two goals, one concerned with the evaluation of normative models, the other with development of prescriptive models. Individual differences have no bearing on normative models, which are justified by analysis, not consensus. Individual differences do, however, suggest where it is possible to try to improve human judgments and decisions through education rather than computers.

Probability is a central concept in utilitarian moral theory, almost impossible to do without. I attempt to clarify the role of probability, so that we can be clear about what we are aiming for when we apply utilitarian theory to real cases. I point out the close relationship between utilitarianism and expected-utility theory, a normative standard for individual decision-making. I then argue that the distinction between “ambiguity” and risk is a matter of perception. We do not need this distinction in (...) the theory itself. In order to make this argument I rely on the personalist theory of probability, and I try to show that, within this theory, we do not need to give up completely on the idea that a “true probability” exists. Finally, I discuss several examples of applied utilitarianism, emphasizing the role of probability in each example: reasonable doubt, the precautionary principle in risk regulation, charity, climate change, and voting.

The heuristics-and-biases approach requires a clear separation of normative and descriptive models. Normative models cannot be justified by intuition, or by consensus. The lack of consensus on normative theory is a problem for prescriptive approaches. One solution to the prescriptive problem is to argue contingently: if you are concerned about consequences, here is a way to make them better.

Deliberative thinking often consists of several steps, each involving a switch decision. These decisions may be influenced by confidence in the thinking done so far. Individuals may differ in their tolerance of low confidence and thus may arrive at unjustified high confidence too soon, either from trusting their intuition or by bolstering an initially favored conclusion.

The idea that time does not exist is, for many, unthinkable: time must exist. Almost every experience we have tells us so. There has been plenty of debate around what time is like, but not whether it exists. The goal of this book is to make the absence of time thinkable. Time might not exist. Beginning with an empirically flavoured examination of the 'folk' concept of time, the book explores the implications this has for our understanding of agency, and the (...) extent to which our best physics and best metaphysics are compatible with a timeless conception of reality.

The methods of experiments in the social sciences should depend on their purposes. To support this claim, I attempt to state some general principles relating method to purpose for three of the issues addressed. (I do not understand what is not a script, so I will omit that issue.) I illustrate my outline with examples from psychological research on judgment and decision making (JDM).
