This is the correspondence (1959–1969), on the nature of the evolutionary process, between the biologist Theodosius Dobzhansky and the historian John C. Greene.
In philosophy, a debate can live forever. Nowhere is this more evident than in ethics, a field that is fueled by apparently intractable dilemmas. To promote the wellbeing of many, may we sacrifice the rights of a few? If our actions are predetermined, can we be held responsible for them? Should people be judged on their intentions alone, or also by the consequences of their behavior? Is failing to prevent someone’s death as blameworthy as actively causing it? For generations, questions (...) like these have provoked passionate arguments and counterarguments, but few clear answers. Here, we offer a psychological account of why philosophical dilemmas arise, why they resist resolution, and why scientists should pay attention to them. Building on a family of recent proposals (Cushman & Young, 2009; Greene, 2008; Sinnott- Armstrong, 2008), we argue that dilemmas result from conflict between dissociable psychological processes. When two such processes yield different answers to the same question, that question becomes a “dilemma”. No matter which answer you choose, part of you walks away dissatisfied. This explanation of philosophical dilemmas has an important payoff for psychological research, and we discuss two specific cases in which it has yielded promising results. In each case, social neuroscience has played an important role in distinguishing the psychological processes responsible for producing a dilemma. This, we suggest, is no accident; cognitive neuroscientific methods are particularly well-suited to dissociating independent psychological processes (Henson, 2006). Consequently, philosophers’ dilemmas provide a reliable guide toward productive cognitive neuroscience by identifying the contours of distinct psychological process. The research we review below focuses particularly on moral dilemmas, which is our own area of expertise. The psychological processes that contribute to moral judgment are of interest in their own right, and play a central role in social cognition.. (shrink)

Modality specificity in priming is taken as evidence for independent perceptual systems. However, Easton, Greene, and Srinivas (1997) showed that visual and haptic cross-modal priming is comparable in magnitude to within-modal priming. Where appropriate, perceptual systems might share like information. To test this, we assessed priming and recognition for visual and auditory events, within- and across- modalities. On the visual test, auditory study resulted in no priming. On the auditory priming test, visual study resulted in priming that was only marginally (...) less than within-modal priming. The priming results show that visual study facilitates identification on both visual and auditory tests, but auditory study only facilitates performance on the auditory test. For both recognition tests, within-modal recognition exceeded cross-modal recognition. The results have two novel implications for the understanding of perceptual priming: First, we introduce visual and auditory priming for spatio-temporal events as a new priming paradigm chosen for its ecological validity and potential for information exchange. Second, we propose that the asymmetry of the cross-modal priming observed here may reflect the capacity of these perceptual modalities to provide cross-modal constraints on ambiguity. We argue that visual perception might inform and constrain auditory processing, while auditory perception corresponds to too many potential visual events to usefully inform and constrain visual perception.

Abstract In the contemporary literature on self-knowledge discussion is framed by and large by two competing models of self-knowledge: the observational (or perceptual) model and the constitutive model. On the observational model self-knowledge is the result of ?cognitively viewing? one's mental states. Constitutive theories of self-knowledge, on the other hand, hold that self-knowledge is constitutive of intentional states. That is, self-ascription is a necessary condition for being in a particular mental state. Akeel Bilgrami is a defender of the constitutive model. (...) I argue that the constitutive model gives rise to a regress problem. This paper will focus on that problem as well as its application to Bilgrami's version of the constitutive model. (shrink)
In this essay I argue that Ernst Mayr's idea that the emergence of evolutionary biology in Western thought was delayed by the pernicious influence of the false ideologies of Platonism, Christianity, and physicalism is ahistorical and anti-evolutionary, that similar ideas, especially his antipathy to physicalism, prejudice his account of the transformation of natural history and medical science into biology, that his organicist resolution of the perennial conflict between mechanism and vitalism is an unstable compound of semi-holism and semi-mechanism, that his (...) conception of biology as the true bridge between the sciences and the humanities, ethics, and social theory is open to question (especially as to the adequacy of the theory of natural selection to account for every aspect of human nature), and that his depiction of science as the sovereign key to understanding everything known to exist or happen in this universe cannot be justified at the bar of reason.

This paper uses chronic beryllium disease as a case study to explore some of the challenges for decision-making and some of the problems for obtaining meaningful informed consent when the interpretation of screening results is complicated by their probabilistic nature and is clouded by empirical uncertainty. Although avoidance of further beryllium exposure might seem prudent for any individual whose test results suggest heightened disease risk, we will argue that such a clinical precautionary approach is likely to be a mistake. Instead, (...) advice on the interpretation of screening results must focus not on risk per se, but on avoidable risk, and must be carefully tailored to the individual. These points are of importance for individual decision-making, for informed consent, and for occupational health. (shrink)
The socially responsible investment industry (SRI) is slowly changing from a screening, avoidance paradigm to a comprehensive paradigm that seeks to affect corporate behavior. Credible rating systems are a key component of this sea change. Reliable and recognizable social and environmental metrics are critical to this progress. The Total Social Impact (TSI) rating approach is a new social metric scheme based on a comprehensive rating of stakeholder issues. This paper describes the evolution of SRI ratings and the role that TSI (...) hopes to play in affecting business behavior by promoting principled business leadership. (shrink)
Stanovich & West (S&W) appear to overlook the adaptivity of variation. Behavioral variability, both between and within individuals, is an absolute necessity for phylogenetic and ontological adaptation. As with all heritable characteristics, inter-individual behavioral variation is the foundation for natural selection. Similarly, intra-individual variation allows a broad exploration of potential solutions. Variation increases the likelihood that more optimal behaviors are available for selection. Four examples of the adaptivity of variation are discussed: (a) Genetic variation as it pertains to behavior and (...) natural selection; (b) behavioral and cognitive aspects of mate selection which may facilitate genetic diversity; (c) variation as a strategy for optimizing learning through greater exploration; and (d) behavioral variation coupled with communication as a means to propagate individually discovered behavioral success.

: Stem cell therapies should be available to people of all ethnicities. However, most cells used in the clinic will probably come from lines of cells stored in stem cell banks, which may end up benefiting the majority group most. The solution is to seek additional funding, earmarked for lines that will benefit minorities and offered as a public expression of apology for past discrimination.
There is a sizeable group of self-described Christian companies which have declared their belief in the successful merging of biblical principles with business activities. As these companies have become more visible, an increasing number of anecdotal newspaper and magazine articles about these companies have appeared. Surprisingly, no rigorous research has been conducted prior to our recent study. This article provides national estimates of the size and predominant characteristics of self-identified Christian companies. In addition, the study investigated the types of relationships (...) these companies maintained with their employees, customers, communities, and suppliers. (shrink)
The three introductory questions posed by Hobson et al. point toward further investigations of cellular, circuit, and systems mechanisms involved in cognitive function that include the effect of CNS-state related modulatory systems on these mechanisms. [Hobson et al.].
There is currently a lively debate about the nature of trust and the conditions necessary to establish and sustain it. Yet, to date, there has been little systematic exploration of these issues. While social scientists are beginning to tease out the nature of trust, there are few published accounts exploring these themes through empirical work There is thus a need for empirically based research, which intelligently unravels this complexity to support all stakeholders in the health arena. This multidisciplinary volume addresses (...) this gap by contributing substantively to the exploration of trust in the experience, practice and organization of health. The authors examine a range of significant conceptual themes in relation to trust, including trust and auditing, consent, expert knowledges and social capital. Through reflecting on these emergent themes, the collection is a landmark contribution to the theoretical and empirical work on trust. (shrink)
How do people manage to refer to chocolate, despite knowing so little about it? Traditional semantic externalism gives a two-part answer, a negative claim that meanings are not determined inside speakers' heads, and a positive claim that meanings are fixed by external factors. This gets the semantics of ‘chocolate’ half right: the negative claim is correct, but the positive claim is not. There is nothing special about ‘chocolate’, and scientifically respectable natural-kind terms also fail to live up to the positive (...) expectations of traditional externalism. However, kind-term indeterminacy is compatible with important advances associated with externalism's de re understanding of kind terms. (shrink)
Recent research in moral psychology highlights the role of emotion and intuition in moral judgment. In the wake of these findings, the role and significance of moral reasoning remain uncertain. In this article, we distinguish among different kinds of moral reasoning and review evidence suggesting that at least some kinds of moral reasoning play significant roles in moral judgment, including roles in abandoning moral intuitions in the absence of justifying reasons, applying both deontological and utilitarian moral principles, and counteracting automatic (...) tendencies toward bias that would otherwise dominate behavior. We argue that little is known about the psychology of moral reasoning and that it may yet prove to be a potent social force. (shrink)
While there is much evidence for the influence of automatic emotional responses on moral judgment, the roles of reflection and reasoning remain uncertain. In Experiment 1, we induced subjects to be more reflective by completing the Cognitive Reflection Test (CRT) prior to responding to moral dilemmas. This manipulation increased utilitarian responding, as individuals who reflected more on the CRT made more utilitarian judgments. A follow-up study suggested that trait reflectiveness is also associated with increased utilitarian judgment. In Experiment 2, subjects (...) considered a scenario involving incest between consenting adult siblings, a scenario known for eliciting emotionally driven condemnation that resists reasoned persuasion. Here, we manipulated two factors related to moral reasoning: argument strength and deliberation time. These factors interacted in a manner consistent with moral reasoning: A strong argument defending the incestuous behavior was more persuasive than a weak argument, but only when increased deliberation time encouraged subjects to reflect.

In this paper we challenge the moral consensus against selection for disability. Our discussion will concern only those disabilities that are compatible with a life worth living from the point of view of the disabled individual. We will argue that an influential, impersonal argument against selection for disability falls to a counterexample. We will then show how the reach of the counterexample can be broadened to make trouble for anyone who objects to selection for disability. If we are right about (...) the problems for objections to selection for disability, why are objections are so widespread? We suggest that intuitions are being skewed against selection for disability by certain quirks in the usual ways of presenting the issue. Nevertheless, we must confess to finding our own result surprising. (shrink)
As the world watched the Fukushima reactors spew incalculable quantities of radionuclides into the sea and air and wondered what effect this would have on our health and that of generations to come, the warnings of Dr. Alice Stewart about low-dose radiation risk assumed a terrible timeliness. As industry, governments, and the media attempted to quiet the alarms, assuring us that radioactive releases will dilute and disperse and become too miniscule to matter, the reassurances of Sir Richard Doll, foremost among (...) Stewart's detractors, also became relevant. It is clear, as proponents and opponents of nuclear energy thrash it out, that there is not much more scientific consensus about the hazards of low-dose radiation .. (shrink)
Abstract Ethical action takes place when spaces are opened for concrete choices made by situated human beings. Enmeshed in relationships and projects, such human beings must attend to the impinging social and political contexts and attempt to overcome the carelessness, systematization, and neglect that stand in the way of morality. Unable to depend on abstract formulations or ahistorical norms, they must continue clarifying their experience and creating their values by means of continuing dialogue. Carried on in the clearest language possible, (...) conducted against backgrounds of intersubjectively lived life, the dialogue must be governed by agreed?upon rules of civility and friendship. The ethical commitments that arise out of communication of this kind must be marked by passion, by an attentiveness to the deficiencies, the particularities, the possibilities of the world. They must be part of a community in?the?making, with more and more persons included, all articulating visions of still untapped possibility. (shrink)
The scientific, ethical, and policy issues raised by research involving the engraftment of human neural stem cells into the brains of nonhuman primates are explored by an interdisciplinary working group in this Policy Forum. The authors consider the possibility that this research might alter the cognitive capacities of recipient great apes and monkeys, with potential significance for their moral status.
If stem cell-based therapies are developed, we will likely confront a difficult problem of justice: for biological reasons alone, the new therapies might benefit only a limited range of patients. In fact, they might benefit primarily white Americans, thereby exacerbating long-standing differences in health and health care.

One class of argument against cloning human beings in the contemporary literature focuses on the bad consequences that will befall the clone or “later-twin.” In this paper I consider whether this line of argumentation can be blocked by invoking Parfit’s non-identity problem. I canvass two general strategies for solving the non-identity problem: a consequentialist strategy and a non-consequentialist, rights based strategy. I argue that while each general strategy offers a plausible solution to the non-identity problem as applied to the cases (...) most frequently discussed in the non-identity problem literature, neither provides a reason for puttingaside the non-identity problem when applied to cloning. I conclude (roughly) that the non-identity problem does serve to block this class of argument against cloning. (shrink)
Tradycyjne teorie psychologii moralności podkreślają rolę rozumowania i „wyższych procesów poznawczych”, podczas gdy ostatnie prace z tego zakresu uwypuklają udział emocji. W niniejszym artykule rozpatruję dane pochodzące z neuroobrazowania wspierające teorię sądzenia moralnego, zgodnie z którą zarówno procesy „poznawcze”, jak i emocjonalne pełnią istotne a czasami wzajemnie konkurencyjne role. Dane te wskazują, że rejony mózgu związane z kontrolą poznawczą (przednia część zakrętu obręczy i grzbietowo boczna kora przedczołowa) są zaangażowane w rozwiązywanie trudnych moralnych dylematów, w których wartości utylitarne wymagają naruszenia (...) „osobistej” sfery moralnej, co wiąże się ze wzrostem aktywności rejonów mózgu związanych z emocjami i poznaniem społecznym (przyśrodkowa kora przedczołowa, górna bruzda skroniowa, tylna część zakrętu obręczy, bieguny skroniowe, ciało migdałowate). Odkryliśmy także, że aktywność w~obszarach mózgu obejmujących przednią część grzbietowo bocznej kory przedczołowej prognozuje różnice w sądzeniu moralnym, w odmiennych warunkach — obszary te wykazują większą aktywność podczas wydawania sądów o~charakterze utylitarnym. Przypuszczam też, że coraz lepsze rozumienie fizjologicznych i neuronaukowych podstaw wydawania sądów moralnych może mieć wpływ na rozwiązywanie dylematów moralnych w~świecie realnym. (shrink)
This essay examines the role of data and program?code archives in making economic research ?replicable.? Replication of published results is recognized as an essential part of the scientific method. Yet, historically, both the ?demand for? and ?supply of? replicable results in economics has been minimal. ?Respect for the scientific method? is not sufficient to motivate either economists or editors of professional journals to ensure the replicability of published results. We enumerate the costs and benefits of mandatory data and code archives, (...) and argue that the benefits far exceed the costs. Progress has been made since the gloomy assessment of Dewald, Thursby and Anderson some 20 years ago in the American Economic Review, but much remains to be done before empirical economics ceases to be a ?dismal science? when judged by the replicability of its published results.

An analysis of the business ethics of the African-American church during and after Reconstruction reveals that it is a conflicted ethic, oscillating between two poles. The first is the sacralization of the business ethic of Booker T. Washington, in which self-help endeavors which valorize American capitalism but are preferentially oriented to the African-American community are advanced as the best and only options for economic uplift. The second is the “Blackwater” tradition, which rejects any racial discrimination and insists upon social justice. (...) The inability of the Washingtonian business ethic to address the needs of the Black underclass are explored. A new business ethic is called for, which would be committed to meeting the basic needs of the most disadvantaged members of American society and those of the “international poor.”. (shrink)
We report on the deliberations of an interdisciplinary group of experts in science, law, and philosophy who convened to discuss novel ethical and policy challenges in stem cell research. In this report we discuss the ethical and policy implications of safety concerns in the transition from basic laboratory research to clinical applications of cell-based therapies derived from stem cells. Although many features of this transition from lab to clinic are common to other therapies, three aspects of stem cell biology pose (...) unique challenges. First, tension regarding the use of human embryos may complicate the scientific development of safe and effective cell lines. Second, because human stem cells were not developed in the laboratory until 1998, few safety questions relating to human applications have been addressed in animal research. Third, preclinical and clinical testing of biologic agents, particularly those as inherently complex as mammalian cells, present formidable challenges, such as the need to develop suitable standardized assays and the difficulty of selecting appropriate patient populations for early phase trials. We recommend that scientists, policy makers, and the public discuss these issues responsibly, and further, that a national advisory committee to oversee human trials of cell therapies be established. **NB we did not reccommend a NAC, we think it might be appropriate**.

Reproductive technologies do not allow us to choose future people, but they do change who will exist. Confusion arises because of the different senses in which ”identity’ is used in ethical debate. I distinguish qualitative, cultural, and numerical identity. Reproductive choices do impact the qualitative features of children in ways that affect wellbeing, both directly and indirectly via cultural identification. I explain how the nonidentity problem makes it difficult to say what, if anything, is wrong with risky reproductive choices, and (...) I outline four strategies or responding to the non-identity problem. (shrink)
