The language of evolutionary biology and psychology is built on concepts applicable in the first instance to individual strategic rationality but extended to the level of genetic explanation. Current discussions of mental disorders as evolutionary adaptations would apply that extended language back to the individual level, with potentially problematic moral/political implications as well as possibilities of confusion. This paper focuses on one particularly problematic area: the explanation of women's greater tendency to depression. The suggestion that there are "good evolutionary reasons" (...) for depression makes sense, and might be helpful to note in therapy, as implying that the tendency is not a defect. However, evolutionary adaptiveness should not be confused with individual or psychological adaptiveness. Besides making reference to an earlier environment, it presupposes a strategic standpoint that may not accord with the legitimate interests of the individual, as this example makes vivid. (shrink)

In the real world, there are choices between large, delayed, punctate rewards and small, more immediate rewards as well as choices between patterns and acts. A common element in these situations is the choice between long- and short-term interests. Key issues for future research appear to be how acts are restructured into larger patterns of behavior, and whether, as Rachlin implies, pattern perception is the cause of pattern generation.

This essay addresses recent claims about the compatibility of the sociobiological theory of reciprocal altruism with standard Western formulations of the Golden Rule. Derek Parfit claims that the theory of reciprocal altruism teaches us to be “reciprocal altruists,” who benefit only those people from whom we can reasonably expect benefits in the future. The Golden Rule, on the other hand, teaches us to benefit anyone regardless of their intention or ability to return the favor, or as Parfit puts it, the (...) Golden Rule teaches us to be “suckers.” I argue that this distinction is founded on a misconception of the nature of the theory of reciprocal altruism, which is sociobiological as opposed to moral, and that this distinction accordingly confuses is with ought. Sociobiological theories may explain underlying psychological motivations in individuals (and perhaps even in populations), but these theories do not prescribe any sort of moral behavior. Furthermore, the theory of reciprocal altruism does not imply mental states of which agents are aware. The unconscious motivations assumed by this theory are in fact compatible with certain formulations of the Golden Rule; I will accordingly argue for the view that certain words with moral content related to the Golden Rule—such as “altruism” and “selfishness”—exist only insofar as they are social tools, which can further the self-interests of an individual in any group.

Internalists hold that all reasons derive from existing motivations. They also hold that agents act irrationally when they fail to act on the strongest reasons they have. Emotions can make one act irrationally. But depression as an emotion tends to remove the motivation to act at the same time as it causes irrational inaction. If depression can cause irrationality, then the reasons to act must remain. Hence the internalist must explain how reasons can remain if depression removes motivation. This paper (...) does so by arguing that the cognitive, evaluative aspect of motivation remains when the dispositional and affective aspects are removed. (shrink)

Joint action is a growing field of research, spanning across the cognitive, behavioral, and brain sciences as well as receiving considerable attention amongst philosophers. I argue that there has been a significant oversight within this field concerning the possibility that many joint actions are driven, at least in part, by agents' social motivations rather than merely by their shared intentions. Social motivations are not directly related to the (joint) target goal of the action. Instead, when agents are mutually socially motivated (...) in joint action this is because they find acting with others rewarding in its own right. Moreover the involvement of social motivation in joint action typically enables individuals to achieve the long-term benefits associated with being part of a social bond. I argue that taking social motivations into account better prepares us for explaining a broader range of joint actions, including those that are of an antagonistic, competitive, or explorative character. Finally, I show that recognizing the importance of social motivations entails that joint actions (in general) should be understood as having the two primary functions of (1) achieving the intended target outcome of an action, and (2) attaining the benefits related to being part of a social bond.

I offer a novel view of the mechanisms underlying the spontaneous facial expression of emotion. According to my Social Amplification View, facial expressions result from the interplay of two processes: an emotional process that activates specific facial muscles, though not always to the point of visible contraction, followed by a social cognitive process that amplifies these activations so that they may function more effectively as social signals. I argue that SAV outperforms both the Neurocultural View and the Behavioral Ecology View, (...) as well as previously proposed syntheses of these views, in accounting for various empirical findings.

Not by Genes Alone excellently explains Peter J. Richerson and Robert Boyd's important ideas about human gene-culture co-evolution to a broader audience but remains short of a larger vision of civilization. Several decades ago Ralph Burhoe had seen that fertile possibility in Richerson and Boyd's work. I suggest getting past present reductionistic customs to a scientific perspective having an integral place for virtue. Subsystem agency is part of this view, as is the driving role of abundance, whose ultimate origins are (...) in the mysterious, quintessentially energetic Big Bang. The free-rider problem may not impede higher social organization as inexorably as Richerson and Boyd believe; "the tragedy" of enervating leakage from "the commons" may often be less influential than an invigorating flow of externalities to the commons. Eukaryotic origins mark the origin of inevitable wider sharing as higher living systems evolve. I use a metaphor of flesh and spirit in drawing a parallel between that turning point and the wide sharing that occurs in civilization. This helps solve the enigma of the demographic transition. Why do so many productive participants in first-world societies severely restrict their selfish-gene reproduction to below replacement birth rate? It is not because culture is maladaptive but because civilization's brain and womb have become partially differentiated in distinct populations. Considerations of social boundaries, myths of sacrifice, and human creativity help in understanding how human social evolution taps potentials present in reality. Human beings' diverse vigorous activities—the organized ones and the inadvertent ones, the wise and the foolish, the good and the bad, the carefully thoughtful and the merely playful—provide the ground of being, or primordial soup, for cultural entities that transcend our intentions. If we have it right for the most part and are fortunate, we will continue to emerge at higher levels. (shrink)

The standard theories of cooperation in humans, which depend on repeated interaction and reputation effects among self-regarding agents, are inadequate. Strong reciprocity, a predisposition to participate in costly cooperation and the punishment, fosters cooperation where self-regarding behaviors fail. The effectiveness of socially coordinated punishment depends on individual motivations to participate, which are based on strong reciprocity motives. The relative infrequency of high-cost punishment is a result of the ubiquity of strong reciprocity, not its absence.

There has been a long tradition of interpreting Plato as a rational egoist. Over the past few decades, however, some scholars have challenged this reading. While Rational Egoism appeals to many ordinary folk, in sophisticated philosophical circles it has fallen out of favor as a general and complete account of the nature of reasons for action. I argue that while the theory of practical rationality that is often equated with rational egoism—a view that I call ‘Simple-Minded Rational Egoism'—is neither plausible (...) nor endorsed by Plato in his Republic, there is a more complex version of Rational Egoism to which Plato is indeed committed. Moreover, such a conception of practical rationality is not vulnerable to the standard set of objections that contemporary philosophers have made against Rational Egoism. (shrink)

Sexual selection processes have received much attention in recent years, attention reflected in interest in human mate preferences. Among these mate preferences are preferences for physical attractiveness. Preferences in and of themselves, however, do not fully explain the nature of the relationships that individuals attain. A tacit negotiation process underlies relationship formation and maintenance. The notion that preferences for physical attractiveness evolved under parasite-driven “good genes” sexual selection leads to predictions about the nature of trade-offs that individuals make between mates’ (...) physical attractiveness and investment potential. These predictions and relevant data are explored, with a primary emphasis on women’s preferences for men’s qualities. In addition, further implications of trade-offs are examined, most notably (a) the impact of environmental variations on the nature of mating and (b) some effects of trade-offs on infidelity and male attempts to control women.

Sociobiological explanation requires both a reliable and a valid definition of the sociopathy phenotype. Mealey assumes that such reliable and valid definition of sociopathy exists in her A review of psychiatric literature on the diagnosis of antisocial personality disorder clearly demonstrates that this assumption is faulty. There is substantial disagreement among diagnostic systems (e.g., RDC, DSM-III) over what constitutes the antisocial phenotype, different systems identify different individuals as sociopathic. Without a valid definition of sociopathy, sociobiological theories like Mealey's should be (...) viewed as entirely speculative. (shrink)

Imagine that an anthropologist returns from her study of a group of people and reports the following:They refuse to kill one person even to avert the death of all involved—including that one person;They won’t directly push someone to his death to save the lives of five others, but they will push a lever to kill him to save five others;They punish transgressors because it feels right, even when they expect the punishment to cause far more harm than good—and even when (...) the harm done by the punishment exceeds the harm done by the transgression being punished.The anthropologist’s report might lead us to conclude that these people are at least confused, and perhaps even dangerous.Here’s some bad news. Those people are us. Or so suggests recent research in experimental psychology and the neurosciences. This research indicates that our moral intuitions have a vaguely deontological character and they prompt us to make any number of judgments that appear arbitrary or otherwise unjustified, such ... -/- I contend that Greene partly misunderstands the practical implications of his own principles. If our ordinary moral judgments are to do the strategic work Greene wants them to do, he needs to endorse fullfledged Sidgwickian self-effacement for at least some areas of micro-level decision making. By the lights of some of Greene’s own arguments, people must accept the correctness—and not simply the usefulness—of the relevant intuitions in their personal conduct to satisfy utilitarian standards. I argue that removing utilitarian reasoning from micro-level decision making is consistent with Greene’s preferred strategy of using utilitarianism as a Bcommon currency^ for resolving moral conflict at the institutional level. To clarify upfront: the aim of this paper is to offer an internal criticism rather than to defend (e.g.,) the relevant empirical research, utilitarianism, self-effacement, and so on. I’m making an argument about where Greene’s own psychological and philosophical commitments should take him. (shrink)

States are ill equipped to meet the challenges of a globalized world. The concept of citizenship with its rights and obligations, including the allegiance owed, is too narrowly defined to exist only between individuals and a state. Today, people identify with, and pay allegiance to, many organizations beyond the state. This article suggests that citizenship could be extended further and be possible between individuals and quasi-governmental organizations, as well as non-governmental organizations, such as churches, clubs, interest groups, functional organizations and (...) profit firms. Due to the larger set of types of citizenship individuals could choose from, their preferences would be better fulfilled and, due to the competition for citizens induced among organizations, the efficiency of public activity would be raised.

Sympathy and other moral emotions described by David Hume (1740/1978) and Adam Smith (1759/1966) motivate people to incur a host of costs they could easily avoid. Such emotions pose a challenge to evolutionary biologists, who have long stressed the primacy of narrow self-interest in Darwinian selection. In earlier work, I argued (Frank, 1987, 1988) that natural selection might have favored moral sentiments because of their capacity to facilitate solutions to one-shot social dilemmas. Here, I present a capsule summary of the (...) basic argument. (shrink)

For the larger part of modern western intellectual history, it has been assumed that the study of morality and religion requires special methodology, insulated from, and in some important aspects incongruent with, the scientific method commonly used in the realm of natural sciences. Furthermore, even if it would be granted that moral and religious behavior is amendable to scientific analysis, the prospects of using evolutionary theory in particular to do the heavy lifting in explanation of these phenomena have been bleak, (...) since many scholars doubted that a biological theory could possibly offer any valuable contribution. Recent advances in the fields of Evolutionary Ethics and Cognitive Science of Religion disprove both claims, emphasizing empirically founded explanations, demonstrating extraordinarily high degree of methodological consilience, and revealing utmost importance of the application of evolutionary theory in fields of study once deemed to be exclusive domains of social sciences and philosophy.

Rachlin's attack on the internal commitment model rests on the demonstrably false claim that self-punishment does not exist. He is correct that habits are an effective device for solving self-control problems, but his additional claim that they are the only such device makes it hard to explain how good habits develop in the first place. Someone with a self-control problem would always choose the spuriously attractive reward, which, over time, would create bad habits.

This article reviews Thomas Donaldson and Thomas Dunfee's new book Ties That Bind. The article argues that the book is a helpful elaboration of Donaldson and Dunfee's Integrative Social Contracts Approach, particularly with regard to their specification of hypernorms. The article also presents Donaldson and Dunfee's argument with regard to how the hypernorm of necessary social efficiency applies to bribery and raises questions about the extent to which human moral behavior might be hardwired.

Mealey distinguishes two types of sociopathy: (1) or obligate, and (2) or facultative. Either sociopathy evolved twice, or one form is derived from the other, e.g., through: (1) genetic assimilation generating polymorphism in the relative strength of biases favoring the development of otherwise facultative strategies, or (2) independently heritable but strategically relevant characteristics biasing the optimal selection of facultative strategies.

The main intent of this paper is to give an account of the relationship between bio-cognition and culture in terms of coevolution, analysing religious beliefs and language evolution as case studies. The established view in cognitive studies is that bio-cognitive systems constitute a constraint for the shaping and the transmission of religious beliefs and linguistic structures. From this point of view, religion and language are by-products or exaptations of processing systems originally selected for other cognitive functions. We criticize such a (...) point of view, showing that it paves the way for the idea that cultural evolution follows a path entirely autonomous and independent from that of biological evolution. Against the by-product and exaptation approaches, our idea is that it is possible to interpret religion and language in terms of coevolution. The concept of coevolution involves a dual path of constitution: one for which biology (cognition) has adaptive effects on culture, the other for which, in turn, forms of culture have adaptive effects on biology (cognition). This dual path of constitution implies that religion and language are (at least in some aspects) forms of biological adaptations. (shrink)

RÉSUMÉ De l'avis de plusieurs, il existe une tension entre le modèle « naturaliste » des émotions qui inspire les psychologues évolutionnistes et le modèle des constructionnistes sociaux. D'un côté, il semble que les émotions sont innées, rigides et panculturelles ; de l'autre, elles sont conçues comme des artefacts culturels, changeant au gré des arrière-plans culturels. Nous examinons chacune des deux approches et montrons que l'approche naturaliste n'est pas incompatible avec une forme de constructionnisme faible, en ce que la première (...) peut tenir compte d'un certain degré de plasticité. Nous soutenons qu'en fait les deux courants devraient être vus comme offrant des points de vue différents, mais complémentaires, sur les mêmes phénomènes. Cependant, une part du domaine des émotions étudiée par les constructionnistes échappe aux efforts d'intégration. Une façon de remédier à la situation est de proposer un réaménagement conceptuel du domaine. Par exemple, Griffiths propose que la solution passe par l'élimination du concept d’« émotion ». Quoique notre investigation des différentes formes d'émotions suggère un certain scepticisme concernant l'utilité théorique du concept d’« émotion », nous croyons qu'il est trop tôt pour en annoncer la mort. ABSTRACT According to many, there is an incongruity between the naturalist's model of emotions that inspired the evolutionary psychologists and the social constructionist's model. In brief, the naturalists propose that emotions are innate, rigid and pancultural ; whereas the social constructionists believe that emotions are cultural artefacts without any biological reality. We examine each approach and show that the naturalists' view is not incompatible with a weak form of constructionism. We argue that in fact the two positions should be considered as offering different but complementary views of the same phenomena. However, a part of the domain of emotions studied by the social constructionists escapes the attempt at integration. One way to solve this problem is to reconfigure the domain. Griffith proposed to do so by eliminating the concept of “emotion”. Our investigation of different forms of emotions suggests that if scepticism concerning the theoretical utility of the concept of “emotion” is grounded, it is still too early to proclaim its death.

There may be evolutionary as well as economic reasons why organisms generally act impulsively. I discuss this possibility and suggest some follow-up experiments that may clarify the exciting empirical and theoretical contributions made by the experiments discussed in the target article.

Mealey proposes two categorical classes of sociopath, primary and secondary. I criticize this distinction on the basis that constructs of this kind have proved unrealistic in personality taxonomy and that dimensional systems capture reality much more successfully. I suggest how such a system could work in this particular context.

Behavioral biologists have long sought to link behavioral units (e.g., aggression, depression, sociopathy) with biological units (e.g., genes, neurotransmitters, hormones, neuroanatomical loci). These units, originally contrived for descriptive purposes, often lead to misunderstandings when they are reified for purposes of causal analysis. This genetic and biochemical explanation for sociopathy reflects such problems.

“Hard obscurantism” is a species of the genus scholarly obscurantism. A rough intensional definition of hard obscurantism is that models and procedures become ends in themselves, dissociated from their explanatory functions. In the present article, I exemplify and criticize hard obscurantism by examining the writings of eminent economists and political scientists.

ABSTRACT This Rejoinder to the comments in the Symposium on my Article focuses on the nature of emotion in general; on specific emotions, notably anger, enthusiasm, and love; and on the relation between emotions and rationality. It also expands on some themes from the Article, notably by providing historical evidence for the claim that enthusiasm can generate inaction-aversion.

ABSTRACT The article aims at contributing to the unification of history and psychology by studying the expressions of anger and enthusiasm in several historical contexts. These mainly include France and America in the eighteenth century, but also more recent episodes of transitional justice. In addition it aims at drawing the attention of psychologist to the understudied emotion of enthusiasm. To this end, it also considers how Hume and Kant treated this emotion.

In this paper, I articulate Heidegger’s notion of Befindlichkeit and show that his phenomenological account of affective existence can be understood in terms of contemporary work on emotions. By examining Heidegger’s account alongside contemporary accounts of emotions, I not only demonstrate the ways in which key aspects of the former are present in the latter; I also explicate in detail the ways in which our understanding of Befindlichkeit and its relationship to moods and emotions can benefit from an empirically-informed study (...) of emotions.

This commentary extends arousal theory to suggest an explanation for the well-established inverse correlation between church attendance and involvement in crime.

In behavioral ethics today, there is debate as to which theory of moral development is the best for understanding ethical decision making, thereby facilitating ethical behavior. This debate between behavioral ethicists has been profoundly influenced by the field of moral psychology. Unfortunately, in the course of this marriage between moral psychology and business ethics and subsequent internal debate, a simple but critical understanding of human being in the field of management has been obscured; i.e., that morality is not a secondary (...) phenomenon arising out of something else. Therefore, in this paper, we will argue that there is a need in behavioral ethics to shift our understanding away from the influence of contemporary moral psychology and back to management theorist Ghoshal’s :75–91, 2005) view of what it means to be human in which the moral is fundamental. To assist in this labor, we will build on the philosophical work of Emmanuel Levinas who sees ethics, regardless of the setting, as a metaphysical concern. What this means is that Levinas sees the essential moral character of human life and the reality of human agency as ontologically fundamental, or constitutive of human nature itself. In other words, the ethical is the “first cause” in regard to understanding the nature and action of the individual, including within organizations. Thus, morality in any sphere of human endeavor, including in business, is not merely epiphenomenal to some more fundamental reality. (shrink)

This article argues that the price obtainable in an open market provides the best standard for determining the justice or injustice of the price of a product. The article argues that this standard, which is closely related to positions which have been held for hundreds of years, is superior to several alternative conceptions of the just price that have been put forward in recent years and is not subject to fundamental criticisms which can be addressed to them. The article also (...) shows how this standard is grounded in more fundamental principles of justice such as desert and equality. (shrink)

Loyalty is a much-discussed topic among business ethicists, but this discussion seems to have issued in very few clear conclusions. This article builds on the existing literature on the subject and attempts to ground a definite conclusion on a limited topic: whether, and under what conditions, it makes sense for an employee to offer loyalty to his employer. The main ways in which loyalty to one’s employer can contribute to human flourishing are that it makes the employee more trustworthy and (...) therefore more valuable as an employee; makes it easier to form authentic relationships in other areas of the employee’s life; expands the employee’s field of interests and gives her or him a richer identity; provides greater motivation for the employee’s work; makes it possible to have a greater unity in the employee’s life; improves the performance of the organization for which the employee works; contributes to the protection of valuable social institutions; and, in so far as many employees share an attitude of loyalty towards the organization which employs them, it becomes possible for this organization to become a true community. Last, but not the least, loyal relationships have an inherent value. The article also reviews the main arguments that have been offered against employee loyalty and concludes that none of them offers a reason why it would be inappropriate in all cases for an employee to be loyal to her or his employer. The force of these arguments depends on the specific attributes of the organization for which the employee works. The main conclusion of the article is that while being a loyal employee involves risk, it has the potential to contribute significantly to the employee’s fulfilment. The main challenge for employees is to identify employers who are worthy of being loyal to. (shrink)

Emotion is critical in Mealey's conceptual arguments. However, several of her assertions about the role of emotion in sociopathy are problematic. Questions are raised regarding the link between lack of anxiety and low levels of secondary emotions such as love and sympathy, the argument that sociopaths are low in anxiety but high in neuroticism, and the designation of anxiety as a secondary emotion.

Rachlin's hyperbolic-discounting model captures basic features of the subtlety of human impulsiveness and self-control and has received convincing experimental support. His distinction between self-control patterns and impulsive acts expands his earlier work to a greater range of self-control behaviors. Possible mechanisms that may weaken or strengthen patterns of self-control are considered.

Recent results from two different studies show evidence of strong emotional engagement in moral dilemmas that require personal involvement or ethical problems that involve significant inter-personal issues. This empirical evidence for a connection between emotional engagement and moral or ethical choices is interesting because it is related to a fundamental survival mechanism rooted in human evolution. The results lead one to question when and how emotional engagement might occur in a professional ethical situation. However, the studies employed static dilemmas or (...) problems that offered only two choices whose outcome was certain or nearly so, whereas actual problems in professional ethics are dynamic and typically involve considerable uncertainty. The circumstances of three example cases suggest that increasing personal involvement and uncertainty could have been perceived as changes, threats, or opportunities and could therefore have elicited an emotional response as a way to ensure the reputation, integrity or success of oneself or a group to which one belongs. Such emotional engagement is only suggested and more studies and experiments are required to better characterize the role of emotional engagement in professional ethics. (shrink)

A quick survey of the literature reveals that authors disagree as to which sentiments are moral and which are not, they disagee as to how to distinguish between moral and other sentiments, and finally that often the same author will claim a sentiment is moral at some times but not at others. These difficulties arise, I argue, from an underlying concept of emotion that I call atomism. Viewing emotions as means of coordination among agents, rather than as psychic atoms, suggests (...) a radically different approach to the question of morality and affects, one where emotions pave the way for normative expectations.

But as for most genes, they are not the units of interest once we get to the network level: it is the whole conspiracy we care about. Biologists, more precisely evolutionary biologists, and not only psychologists and philosophers also speak of modularity. However the way in which this theoretical construct functions in their discipline is relatively different from the role it obtains in evolutionary psychology and cognitive science. Rather than postulating modules to explain particular traits of organisms, such as the (...) specificity of input systems or limitations of human reasoning abilities, biologists originally simply assume that some form of modularity constitutes a precondition of evolution. They argue that, in order for natural selection to fine tune organisms to their environment, different traits must be able to evolve independently from one another. This implies modularity in one form or another. Organisms will only be able to adapt if they do not come all in one piece, so to speak. It must therefore be possible for changes to occur in one characteristic of an animal without those changes having repercussions throughout the whole organism. (shrink)

This paper proposes a semiotic theory of norms—what I term normative semiotics. The paper’s central contention is that social norms are a language. Moreover, it is a language that we instinctively learn to speak. Normative behaviour is a mode of communication, the intelligibility of which allows us to establish cooperative relationships with others. Normative behaviour communicates an actor’s potential as a cooperative partner. Compliance with a norm is an act of communication: compliance signals cooperativeness; noncompliance signals uncooperativeness. An evolutionary model (...) is proposed to explain how this comes about: evolution has generated an instinctual proficiency in working with these signals much like a language—a proficiency that manifests in an emotional context. We see these social rules as possessing a certain ‘rightness’ in normative terms. This adaptive trait is what we call internalization. Internalization enhances the individual’s ability to speak this code. Because these signals communicate who is and who is not a reliable co-operator, sending and receiving cooperation signals is crucial to individual survival. Individuals who internalized the entire process and thus became more adept at speaking the language were at an advantage. Law seeks to shape the language of norms by maintaining the collective standards of society; as such, understanding how and why this normative language emerges is critical to understanding a core function of law.
