Organisms change their shape and behavior during ontogenesis in response to incentives—what biologists call “phenotypic plasticity” or what is called here more specifically “behavioral plasticity.” Such plasticity is usually in the direction of enhancing welfare or fitness. In light of basic concepts in economics, such behavioral plasticity is nothing but rationality. Such rationality is not limited to organisms with neural systems. It also characterizes brainless organisms such as plants, fungi, and unicellular organisms. The gist of the article is the distinction (...) between rationality and intelligence. Whereas rationality is ubiquitous in all organisms, intelligence varies in degrees depending on division of labor that may involve the evolution of a neural system. This article aims to defend the universality of rationality—the Organismus oeconomicus hypothesis. It argues that neither the notion of bounded rationality of behavioral economics nor Herbert Simon’s “procedural rationality” can ultimately undermine the Organismus oeconomicus hypothesis. (shrink)

This chapter offers an overview of four key debates about the roles of emotion in morality. First, many believe that emotions are an important psychological mechanism for explaining altruistic behavior and moral conscience in humans. Second, there is considerable debate about the causal role of affective reactions in moral judgment. Third, some philosophers have argued that emotions have a constitutive role in moral thought and even moral facts. Finally, philosophers disagree about whether affective influence undermines the justification of moral beliefs (...) or, in suitable circumstances, guides us toward moral truth. (shrink)

In this chapter, we will investigate the ramifications of moral knowledge for naturalism (roughly, the view that all that exists is the natural world). Specifically, we will draw attention to a certain problem we face if the world is purely naturalistic. We will then show how theism provides resources for solving this problem. We’ll argue that the fact that we have lots of moral knowledge fi ts better with theism than with naturalism. Specifically, we’ll present reasons to think that (1) (...) naturalists who think we have lots of moral knowledge will have trouble rationally maintaining both their naturalism and their belief that we have such knowledge and (2) theism better explains the fact that we have lots of moral knowledge than naturalism does.

Unlike in physics, the category of thought experiment is not very common in biology. At least there are no classic examples that are as important and as well-known as the most famous thought experiments in physics, such as Galileo’s, Maxwell’s or Einstein’s. The reasons for this are far from obvious; maybe it has to do with the fact that modern biology for the most part sees itself as a thoroughly empirical discipline that engages either in real natural history or in (...) experimenting on real organisms rather than fictive ones. While theoretical biology does exist and is recognized as part of biology, its role within biology appears to be more marginal than the role of theoretical physics within physics. It could be that this marginality of theory also affects thought experiments as sources of theoretical knowledge. Of course, none of this provides a sufficient reason for thinking that thought experiments are really unimportant in biology. It is quite possible that the common perception of this matter is wrong and that there are important theoretical considerations in biology, past or present, that deserve the title of thought experiment just as much as the standard examples from physics. Some such considerations may even be widely known and considered to be important, but were not recognized as thought experiments. In fact, as we shall see, there are reasons for thinking that what is arguably the single most important biological work ever, Charles Darwin’s On the Origin of Species, contains a number of thought experiments. There are also more recent examples both in evolutionary and non-evolutionary biology, as we will show. Part of the problem in identifying positive examples in the history of biology is the lack of agreement as to what exactly a thought experiment is. Even worse, there may not be more than a family resemblance that unifies this epistemic category. We take it that classical thought experiments show the following characteristics: They serve directly or indirectly in the non-empirical epistemic evaluation of theoretical propositions, explanations or hypotheses. Thought experiments somehow appeal to the imagination. They involve hypothetical scenarios, which may or may not be fictive. In other words, thought experiments suppose that certain states of affairs hold and then try to intuit what would happen in a world where these suppositions are true. We want to examine in the following sections if there are episodes in the history of biology that satisfy these criteria. As we will show, there are a few episodes that might satisfy all three of these criteria, and many more if the imagination criterion is dropped or understood in a lose sense. In any case, this criterion is somewhat vague in the first place, unless a specific account of the imagination is presupposed. There will also be issues as to what exactly “non-empirical” means. In general, for the sake of discussion we propose to understand the term “thought experiment” here in a broad rather than a narrow sense here. We would rather be guilty of having too wide a conception of thought experiment than of missing a whole range of really interesting examples. (shrink)

Argues that a coherent theory of ethics requires an account of selfhood.

Is the ability to speak a language an acquired skill? Leading proponents of the generative approach to human language—notably Chomsky (2000) and Pinker (2003)—have argued that the thesis that language capacities are skills is hopelessly confused and at odds with a range of empirical evidence, which suggests that human language capacities are grounded in a biologically inherited set of language instincts or a Universal Grammar (UG). In this paper, we argue that resistance to the claim that human language capacities are (...) skills has been fostered by naïve and implausible conceptions of the nature of skilled action. Correcting these misconceptions about the nature of skilled action breathes new life into the old idea that human language competences are particular kinds of skills and does so in a way that is fully consistent with appeals to the central importance of UG, broadly construed. More generally, we argue that by taking human language capacities to be skills, we capture what is right about the generative program while at the same time avoiding its most serious pitfalls.

In her article "Animals and Moral Agency: The Recent Debate and Its Implications," Grace Clement provides a lucid overview of the debate concerning the possibility of moral action in animals and a suggestive proposal for how to advance this debate. This article takes up certain themes from Clement’s article, themes that, it is argued, are either problematic or insufficiently developed.

In this article I analyze the academic reception of Jonathan Haidt’s seminal article _The emotional dog and its rational tail: A social intuitionist approach to moral judgment_. My thesis is that in the spheres of philosophy and psychology, this article was initially studied within the neurocentric paradigm, which dominated the field of scientific reflection in the fifteen years following its publication. This neurocentric reading established a specific interpretation of the text with several limitations. However, more recently a digital paradigm has (...) emerged and come to prevail in academia, providing a new perspective from which to return to Haidt’s text. Indeed, this approach makes it possible to unravel elements of the famous article that in the neurocentric paradigm went unnoticed by researchers. Moreover, the digital paradigm manages to better integrate Haidt’s seminal article into his later work as a whole. (shrink)

In contemporary Science, Technology and Society studies, Bruno Latour’s Actor Network Theory is often used to study how social change arises from interaction between people and technologies. Though Latour’s approach is rich in the sense of enabling scholars to appreciate the complexity of many relevant technological, environmental, and social factors in their studies, the approach is poor from an ethical point of view: the doings of things and people are couched in one and the same behaviorist vocabulary without giving due (...) recognition to the ethical relevance of human intelligence, sympathy and reflection in making responsible choices. This article argues that two other naturalist projects, the non-teleological virtue ethics of Charles Darwin and the pragmatist instrumentalism of John Dewey can enrich ANT-based STS studies, both, in a descriptive and in a normative sense.

For decades Darwinian processes were framed in the form of the Lewontin conditions: reproduction, variation and differential reproductive success were taken to be sufficient and necessary. Since Buss and the work of Maynard Smith and Szathmary biologists were eager to explain the major transitions from individuals to groups forming new individuals subject to Darwinian mechanisms themselves. Explanations that seek to explain the emergence of a new level of selection, however, cannot employ properties that would already have to exist on that (...) level for selection to take place. Recently, Hammerschmidt et al. provided a ‘bottom-up’ experiment corroborating much of the theoretical work Paul Rainey has done since 2003 on how cheats can play an important role in the emergence of new Darwinian individuals on a multicellular level. The aims of this paper are twofold. First, I argue for a conceptual shift in perspective from seeing cheats as a ‘problem’ that needs to be solved for multi-cellularity to evolve to the very ‘key’ for the evolution of multicellularity. Secondly, I illustrate the consequences of this shift for both theoretical and experimental work, arguing for a more prominent role of ecology and the multi-level selection framework within the debate then they currently occupy.

At the end of the most violent century in human history, it is good to take stock of our commitments to human and other life forms, as well as to examine the rights and the duties that might flow from their biological makeup. Professor Thomasma and Professor Loewy have held a long-standing dialogue on whether there are moral differences between animals and humans. This dialogue was occasioned by a presentation Thomasma made some years ago at Loewy's invitation at the University (...) of Illinois, Peoria, Medical Center. During that presentation, Thomasma argued that human beings are sufficiently distinct from other animals genetically and otherwise to justify a moral difference in rights and obligations. In effect, he argued that there are species-specific rights. This essay will pick up the threads of that dialogue. (shrink)

Facts about moral disagreement and human evolution have both been said to exclude the possibility of moral knowledge, but the question of how these challenges interact has largely gone unaddressed. The paper aims to present and defend a novel version of the evolutionary “debunking” argument for moral skepticism that appeals to both types of considerations. This argument has several advantages compared to more familiar versions. The standard debunking strategy is to argue that evolutionary accounts of moral beliefs generate skeptical implications (...) because they attribute those beliefs to factors that are unrelated to their truth. That strategy is vulnerable to “third-factor” responses, which invoke first-order moral claims to challenge the assumption that Darwinian factors and the moral truths are really unrelated in that way. In contrast, our version is immune to those responses, as it does not proceed via assumptions about how Darwinian factors relate to the moral facts. Instead, it focuses on what evolutionary accounts of moral beliefs have to say about the fact that people often reach divergent moral beliefs. The argument thereby illustrates how the debunking strategy can join forces with the argument from moral disagreement. The combination of those strategies presents, we think, a challenge that is more formidable than when they are considered separately. (shrink)

In this article I reevaluate Immanuel Kant's moral philosophy from a post–Darwinian perspective. Taking an evolutionary approach to human reasoning and incorporating some recent work on the science of the emotions, I argue that the Kantian bifurcation of reason and emotion, which underlies his moral philosophy, is no longer tenable. Kant's practical defense of his ethics as being the only option that can save morality from the dangers posed by naturalism is also considered and rejected. Instead, I argue that an (...) evolutionary view of reason and emotion can provide an adequate ground for morality and explore the possibility and advantages of such an ethics. (shrink)

Christian ethics accentuates in manifold ways the unique character of human nature. Personalists believe that the mind is never reducible to material and physical substance. The human person is presented as the supreme principle, based on arguments referring to free-willed actions, the immateriality of both the divine spirit and the reflexive capacity, intersubjectivity and self-consciousness. But since Darwin, evolutionary biology slowly instructs us that morality roots in dispositions that are programmed by evolution into our nature. Historically, Thomas Huxley, “Darwin's bulldog,” (...) agreed with Darwin on almost everything, except for his gradualist position on moral behavior. Huxley's “saltationism” has recently been characterized by Frans de Waal as “a veneer theory of morality.” Does this mark the end of a period of presenting morality as only the fruit of socialization processes (nurture) and as having nothing in common with nature? Does it necessarily imply a corrosion of personalist views on the human being or do Christian ethics have to become familiar again with their ancient roots? (shrink)

In theOrigin of Species, Charles Darwin (1809–82) briefly drew an analogy between languages and species, suggesting that the genealogical relationships between languages provide a model for discussing the descent and modification of species. Further, he suggested that just as languages often contain some vestige of earlier speech, for example silent, unpronounced letters, so the rudimentary organs of animals can provide clues about genealogy and descent.

Cognitive explanations of religious beliefs propose an evolutionary past in which humans had to possess certain cognitive adaptations to survive. The aim of this article is to show that some cognitive accounts may overvalue the putative role of cognition. One such cognitive idea is an assumption that cognition has been evolutionarily shaped only, or most importantly, in the Pleistocene. This idea seems common among writers on the cognitive science of religion (CSR), but is mistaken. Cognition has been shaped throughout evolution. (...) Another idea is that components of religion could not have been produced by natural selection (the hypothesis that religion is a by-product). But the article suggests that there are some domains in the field of religion and religious components that could be acquired and transmitted despite or even against alleged cognitive biases. The aim of this article is to argue for an extended approach that combines a cognitive account with functional naturalistic approaches, including an adaptationist one. Such distinction could imply that cognition is not functional. Obviously, this is not the case since cognition is the process of knowing, and surely knowledge is functional. However, the main argument for such a distinction lies in the key idea of the cognitive account that as far as cognition is functional and adaptive, religious components are not. Functionalism or “adaptivism” concerning cognition contradicts functionalism concerning religion. Numbers of scholars who consider themselves part of CSR seem also to consider both cognition and religion adaptive. However, in regard to components of religion, their adaptive, functional power is only secondary. The article concludes that the study of religion—as the study of cultural evolution in general—should include a pluralistic methodology combining cognitive and evolutionary accounts with the specificity of cultural evolution.

This article provides the first detailed modern examination of Julia Wedgwood’s interventions in the Victorian debate about the origin of language. Wedgwood wanted to understand language, consistently with Darwin’s theory of evolution, as having evolved gradually out of other forms of animal behaviour. She focused specifically on imitative behaviours, siding with the imitative or “bow-wow” theory of language which her father Hensleigh Wedgwood also championed. She opposed the conceptualist or “ding-dong” theory of Max Müller, on which language is the “Rubicon” (...) that radically separates humans from animals. I argue that Julia Wedgwood was right to emphasise that the human capacity for language is continuous with animal behaviours, though she was wrong to reduce this continuity to a single behaviour, imitation. Nevertheless, her language essays remain significant as an early attempt to forge a Darwinian account of language, and they illuminate the fact that women were able to take part in Victorian philosophical debates, including on an abstract topic such as philosophy of language. The essays also provide entry into Wedgwood’s thought and work more broadly, which are unjustly neglected and deserve to be recovered. (shrink)

This paper argues that the faculty of language comes essentially for free in evolutionary terms, by grace of a capacity shared with some evolutionarily quite distantly related animals for deliberatively planning action in the world. The reason humans have language of a kind that animals do not is because of a qualitative difference in the nature of human plans rather than anything unique to language.

Emotivism has enjoined a revival of sorts over the past few decades, primarily driven by a Darwinian interpretation of the Humean metaethic. Evolutionary ethics, the metaethical view that at the heart of our moral sense lies a set of moral sentiments whose existence 'pre-dates' in evolutionary terms our species' ability to engage in more explicit, cognitive moral deliberations and discourse, whether in the discovery of deontological rules or in the crafting of social contracts, figures prominently in Robert Solomon's work in (...) justice theory and J. Baird Callicott's work in environmental ethics, to name just two efforts to revive emotivism. Though the idea that our moral sense is grounded in our evolved biology lies at the heart of the new ethical emotivism, there has been a curious lack of a truly evolutionary account of the origin of that biological predisposition in the work of Solomon, Callicott, and others involved in the revival. In particular, what is missing is an account of how we evolved our moral sense as an adaptation to the ecology in which our very early ancestors existed. The typical explanation is to treat it as selected for by the pressure to cooperate that bore upon our early ancestors; for example, the advantage that cooperative effort confers in bringing down big game or warding off competing groups. But this type of explanation, I hope to show, rather than providing an account of how our moral sense came to be, actually must presuppose the existence of a rudimentary moral sense. If so, then the origin of our moral sense must be accounted for as an adaptation to our pre-social, ecological environment. As a model for what such an explanation might look like I will use Jared Diamond's recent work in biogeography, Guns, Germs and Steel. (shrink)

Gayon's recent claim that Buffon developed a concept of species as physical individuals is critically examined and rejected. Also critically examined and rejected is Gayon's more central thesis that as a consequence of his analysis of Buffon's species concept, and also of Darwin's species concept, it is clear that modern evolutionary theory does not require species to be physical individuals. While I agree with Gayon's conclusion that modern evolutionary theory does not require species to be physical individuals, I disagree with (...) his reasons and instead provide logical rather than historical reasons for the same conclusion.

This article discusses recent naturalistic theories of religion from the viewpoint of how the deal with the issue of the origins of religion. It will be argued that the theories can be divided according to if they view religion as being an adaptation or not, on the other hand, and if they consider it to be mostly natural or cultural on the other. On the basis of this discussion, it is suggested that a cognitive mechanism referred to here as the (...) narrative drive seem to have a fundamental role to play in the formation of religious beliefs and, thus, in the origins of religion.

Theories in the cognitive science of religion (CSR) are sometimes seen as debunking religious or supernatural beliefs (SBs). To date, arguments have been produced by proponents on both sides, with some claiming that debunking would result and others claiming that it would not. In this paper, I depart from the approach taken by others and offer an approach based in broadly Bayesian methods of updating subjective probability assignments, including classical Bayesian formulas as well as comparative ratios and Jeffrey conditionalization. I (...) argue that debunking may take place, but only if specified conditions are met. One way to show that debunking takes place would be to show that the probability of some CSR theory naturalistically explaining SBs diminishes when it is postulated that SBs have epistemic warrant. Another alternative would be to show that CSR theories are less likely to succeed in explaining the origin of SBs if SBs have warrant than if they lack warrant. It can also be helpful to consider the role played by uncertain and even ineffable judgments. Either way, debunking SBs does not follow simply from CSR but must be considered in light of prior epistemic commitments and the role they play in evaluating probabilities. (shrink)

Fundamental problems of environmental sustainability, including climate change and fisheries management, require collective action on a scale that transcends the political and cultural boundaries of the nation-state. Rational, self-interested neoclassical economic theories of human behavior predict tragedy in the absence of third party enforcement of agreements and practical difficulties that prevent privatization. Evolutionary biology offers a theory of cooperation, but more often than not in a context of discrimination against other groups. That is, in-group boundaries are necessarily defined by those (...) excluded as members of out-groups. However, in some settings human’s exhibit behavior that is inconsistent with both rational economic and group driven cooperation of evolutionary biological theory. This paper reports the results of a non-cooperative game-theoretic exercise that models a tragedy of the commons problem in which groups of players may advance their own positions only at the expense of other groups. Students enrolled from multiple universities and assigned to different multi-university identity groups participated in experiments that repeatedly resulted in cooperative outcomes despite intergroup conflicts and expressions of group identity. We offer three possible explanations: students were cooperative because they were in an academic setting; students may have viewed their instructors as the out-group; or the emergence of a small number of influential, ethical leaders is sufficient to ensure cooperation amongst the larger groups. From our data and analysis, we draw out lessons that may help to inform approaches for institutional design and policy negotiations, particularly in climate change management. (shrink)

Current debates about “Darwinizing culture” have typically focused on the validity of memetics. In this article we argue that meme-like inheritance is not a necessary requirement for descent with modification. We suggest that an alternative and more productive way of Darwinizing culture can be found in the application of phylogenetic methods. We review recent work on cultural phylogenetics and outline six fundamental questions that can be answered using the power and precision of quantitative phylogenetic methods. However, cultural evolution, like biological (...) evolution, is often far from treelike. We discuss the problems reticulate evolution can cause for phylogenetic analyses and suggest ways in which these problems can be overcome. Our solutions involve a combination of new methods for the study of cultural evolution , and the triangulation of different lines of historical evidence. Throughout we emphasize that most debates about cultural phylogenies can only be settled by empirical research rather than armchair speculation. (shrink)

Sociobiology has always had a strong relationship with classical psychometrics, and with intelligence testing in particular. The major ideological impact of Eugenics prior to 1940 led many psychometricians to adopt a sociobiological perspective, but when this turned out, in the 1960's, to be controversial many of the procedures of classical psychometrics were abandoned. Their place was taken by functional psychometrics, based on criterion reference testing, where the content of test items was related directly to very specific skills which may be (...) required in the work place or other setting, and the use of intervening psychological traits such as intelligence was eliminated. It is demonstrated here that much of the theory of traits can be derived directly from functional psychometrics, without the need to make any sociobiological presuppositions. (shrink)

In recent years, philosophers have come to realize that the relationship between science and values raises questions which are both important and not readily answered. It is true that the major figures in that tradition known as ‘logical empiricism’ appreciated that science always exceeds its empirical grasp and that it is necessary for scientists to be guided and constrained by so-called ‘epistemic values,’ these being values (in the words of one supporter) ‘presumed to promote the truth-like character of science, its (...) character as the most secure knowledge available to us of the world we seek to understand.’ However, these values — such things as internal and external consistency, simplicity, predictive accuracy and fertility, unificatory power (consilience) — were considered special. Inasmuch as they could not be reduced to basic principles of logic — and there were attempts to do this — they were still thought of, in some sense, as beyond the vagaries of human emotion. Their importance was not a function of the individual’s personal inclinations, nor of those of the group, whether this group be understood as a closely knit band of researchers or even up to a complete society.

Hopes of applying the findings and speculations of evolutionary theorizing to the problems of ethics have yielded a program with a bad reputation. At the level of norms – substantival ethics – it has been a platform for some of the more grotesque socio-politico-economic suggestions of our times. At the level of justification – metaethics – it has opened the way to some of the more blatant fallacies in the undergraduate textbook. Recently, however, a number of people, philosophers and biologists, (...) have sensed that a more adequate evolutionary ethics might be possible. United in the conviction that it simply has to matter that we humans are modified monkeys rather than the creation of a Good God, in His image, on the Sixth Day, they argue that recent developments in evolutionary biology, especially those dealing with the genetic basis of social behavior, open the way to a satisfactory biological understanding of morality.

Evolutionary ethics has a bad reputation. But we must not remain prisoners of our past. Recent advances in Darwinian evolutionary biology pave the way for a linking of science and morality, at once more modest yet more profound than earlier excursions in this direction. There is no need to repudiate the insights of the great philosophers of the past, particularly David Hume. So humans’ simian origins really matter. The question is not whether evolution is to be linked to ethics, but (...) how. (shrink)

Does Darwinism generally, and human sociobiology in particular, lead to an unwarranted (and possibly socially offensive) determinism? I argue that one must separate out different senses of determinism, and that once one has done this, a Darwinian approach to human nature can be seen to shed important light on our intuitions about free will, constraint, and control.

El artículo propone poner a prueba la idea comúnmente admitida de que en la concepción aristotélica las emociones tienen una función o fin en el ámbito biológico. Me propongo probar que esta concepción sería más propia de otras posturas, como la tomista y la cartesiana, y especialmente de la darwiniana y neo-darwiniana. Tras presentar en la sección 2 el tipo de explicaciones teleológicas que Aristóteles admite y emplea en biología, analizo en la parte 3 la concepción de las emociones de (...) Descartes y en especial de Darwin y muestro que ellas se adaptan bien al modelo explicativo teleológico aristotélico. En la sección 4, ofrezco varios argumentos con apoyo en los textos biológicos de Aristóteles para mostrar que, en cambio, este tipo de explicaciones teleológicas de las emociones no aparecen con claridad en los escritos biológicos del estagirita, toda vez que lo que encontramos allí es, más bien, explicaciones fisiológico materialistas del carácter de los animales. Por último, sugiero una asimetría con el tratamiento de las emociones desde el punto de vista de la racionalidad práctica que desarrollaré en trabajos ulteriores. (shrink)

RESUMEN Recientes intentos por conectar la ética y la biología aristotélicas marcan una suerte de continuidad entre el carácter de los animales no racionales y de los seres humanos, de modo tal que en la descripción de los caracteres de los animales no racionales puede identificarse el punto de partida biológico del propio ser humano en el desarrollo de su carácter moral. En este artículo, propongo señalar los límites de este tipo de lectura, ya que, entendida de cierto modo, ella (...) implica una continuidad entre la normatividad natural y la normatividadpráctica propia de un naturalismo fundacionalista que no puede atribuirse a Aristóteles. En conexión con ello, sostengo que el concepto de virtud natural no es un concepto natural, sino ético, tal que sólo cobra sentido en el marco de la normatividad práctica; la virtud natural, en este sentido, no forma parte de una explicación genética de la virtud sino de un análisis que va del todo a las partes, de acuerdo al cual ella no es anterior sino posterior a la virtud ética. ABSTRACT A recent trend in Aristotelian scholarship tries to link ethics and biology. Within these attempts, some sort of continuity between the character of non-rational animals and that of human beings has been proposed, so that the starting point ofmoral development could be identified in Aristotle’s description of animal’s character. In this article I argue that this reading should strongly qualified, for understood in some ways it entails a sort of continuity between natural normativity and practical normativity that belongs to an Archimedean ethical naturalism, which cannot be reconstructed from Aristotle’s writings. Connected to this, I argue that the concept of natural virtue is not a natural concept, but an ethical one that only makes sense from within the realm of practical normativity; natural virtue, thus understood, is not part of a genetic explanation of virtue, but emerges from a conceptual whole-part analysis. In this manner, natural virtue is no prior, but posterior to ethical virtue. (shrink)

It is a philosophical truism that we must think of others as moral agents, not merely as causal or statistical objects. But why? I argue that this follows from the best resolution of an antinomy between our experience of morality as necessarily binding on the will and our knowledge that all moral beliefs originate in contingent histories. We can address this antinomy only by understanding moral deliberation via interpersonal relationships, which simultaneously vindicate and constrains morality’s bind on the will. This (...) means that moral agency is fundamentally social. I model an attitude toward our causal nature on sociologist Erving Goffman’s concept of ‘civil inattention’; our social practice of agency requires that we give minimal attention to the contingent origins of moral judgments in ourselves and others. Understood this way, seeing ourselves as moral agents requires avoiding appeal to causal aetiology to settle substantive moral disagreement. (shrink)

This article advocates a naturalist and realist ethics of solidarity. Specifically, it argues that human needs should be met; and that they should be met in harmony with the environment. Realism should include respect for existing cultures and the morals presently being practiced – with reasonable exceptions. Dignity must come in a form understood and appreciated by the person whose dignity is being respected. It is also argued that naturalist ethics are needed to combat liberal ethics, not least because the (...) latter supports today’s inflexible and dysfunctional institutions. In arguing for these positions, reference is made to the naturalist realist ethics of Georges Canguilhem, C.H. Waddington, John Dewey and David Sloan Wilson, all of whom embed the social order in the natural order. (shrink)

The complexity of human societies of the past few thousand years rivals that of social insect societies. We hypothesize that two sets of social “instincts” underpin and constrain the evolution of complex societies. One set is ancient and shared with other social primate species, and one is derived and unique to our lineage. The latter evolved by the late Pleistocene, and led to the evolution of institutions of intermediate complexity in acephalous societies. The institutions of complex societies often conflict with (...) our social instincts. The complex societies of the last few thousand years can function only because cultural evolution has created effective “work-arounds” to manage such instincts. We describe a series of work-arounds and use the data on the relative effectiveness of WWII armies to test the work-around hypothesis. (shrink)

Contrary to widely held assumptions, an evolutionary metaethics need not be non-cognitivist. I define evolutionary metaethics as the claim that certain phenotypic traits expressing certain genes are both necessary and sufficient for explanation of all other phenotypic traits we consider morally significant. A review of the influential cognitivist Immanuel Kants metaethics shows that much of his ethical theory is independent of the anti-naturalist metaphysics of transcendental idealism which itself is incompatible with evolutionary metaethics. By matching those independent aspects to an (...) evolutionary metaethics a cognitivist Kantian evolutionary metaethical theory is a possibility for researchers to consider. (shrink)

Liberal proponents of genetic engineering maintain that developing human germline modification technologies is morally desirable because it will result in a net improvement in human health and well-being. Skeptics of germline modification, in contrast, fear evolutionary harms that could flow from intervening in the human germline, and worry that such programs, even if well intentioned, could lead to a recapitulation of the scientifically and morally discredited projects of the old eugenics. Some bioconservatives have appealed as well to the value of (...) retaining our “given” human biological nature as a reason for restraining the development and use of human genetic modification technologies even where they would tend to increase well-being. In this article, I argue that germline intervention will be necessary merely to sustain the levels of genetic health that we presently enjoy for future generations—a goal that should appeal to bioliberals and bioconservatives alike. This is due to the population-genetic consequences of relaxed selection pressures in human populations caused by the increasing efficacy and availability of conventional medicine. This heterodox conclusion, which I present as a problem of intergenerational justice, has been overlooked in medicine and bioethics due to certain misconceptions about human evolution, which I attempt to rectify, as well as the sordid history of Darwinian approaches to medicine and social policy, which I distinguish from the present argument.

Since Darwin, the idea of psychological continuity between humans and other animals has dominated theory and research in investigating the minds of other species. Indeed, the field of comparative psychology was founded on two assumptions. First, it was assumed that introspection could provide humans with reliable knowledge about the causal connection between specific mental states and specific behaviors. Second, it was assumed that in those cases in which other species exhibited behaviors similar to our own, similar psychological causes were at (...) work. In this paper, we show how this argument by analogy is flawed with respect to the case of second‐order mental states. As a test case, we focus on the question of how other species conceive of visual attention, and in particular whether chimpanzees interpret seeing as a mentalistic event involving internal states of perception, attention, and belief. We conclude that chimpanzees do not reason about seeing in this manner, and indeed, there is considerable reason to suppose that they do not harbor representations of mental states in general. We propose a reinterpretation model in which the majority of the rich social behaviors that humans and other primates share in common emerged long before the human lineage evolved the psychological means of interpreting those behaviors in mentalistic terms. Although humans, chimpanzees, and most other species may be said to possess mental states, humans alone may have evolved a cognitive specialization for reasoning about such states. (shrink)
