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.

According to the received view of evolution, only genes are inherited. From this view it follows that only genetically-caused phenotypic variation is selectable and, thereby, that all selection is at bottom genetic selection. This paper argues that the received view is wrong. In many species, there are intergenerationally-stable phenotypic differences due to environmental differences. Natural selection can act on these nongenetically-caused phenotypic differences in the same way it acts on genetically-caused phenotypic differences. Some selection is at bottom nongenetic selection. The (...) argument against the received view involves a reformulation of the concepts of inheritance and heritability. Inherited factors are all those developmental factors responsible for parent–offspring similarity; some inherited factors are genetic and some are not. Heritable variation is intergenerationally-stable phenotypic variation; some such variation is genetically-caused and some is not.

In ''''A Defense of Evolutionary Ethics'''' (1986), Robert J. Richardsendeavors to explain how moral ''oughts'' can be derived from thescience of evolutionary biology without committing the dreadednaturalistic fallacy. First, Richards assumes that ''ought'' as usedin ethical discourse bears the same meaning as ''ought'' used anywherein science, indicating merely that certain results or behaviors arepredicted based on prior structured contexts. To this extent, themoral behavior of animals, what they ''ought'' to do, could arguablybe predicted by evolutionary biology as effectively as, say,molecular (...) behavior may be predicted by chemistry. But afteracknowledging that biological inferences to this limited senseof ''ought'' were never contested by Moore''s naturalistic fallacy,Richard proposes to add to evolutionary ethics a decision procedureto determine which members of a set of predicted behaviors arethose which truly ought to occur – in the genuinelyprescriptive sense intended by ethical discourse. But theprocedure which Richards fabricates for this purpose appealsto such alleged ''facts'' as cultural conventions and moral opinionpolling, hardly a secure foundation for the sort of scientific ethics promised by Richards at the outset.

Richard Lewontin's (1970) early work on the units of selection initiated the conceptual and theoretical investigations that have led to the hierarchical perspective on selection that has reached near consensus status today. This paper explores other aspects of his work, work on what he termed continuity and quasi-independence, that connect to contemporary explorations of modularity in development and evolution. I characterize such modules and argue that they are the true units of selection in that they are what evolution by natural (...) selection individuates, selects among, and transforms. (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.

Adaptationist accounts of morality attempt to explain the evolution of morality in terms of the selective advantage that judging in moral terms secured for our ancestors (e.g. Ruse 1998; Joyce 2006; Street 2006). So-called by-product explanations of morality have been presented as an alternative to adaptationist accounts (e.g. Prinz 2009; Ayala 2010; cf. Darwin 2004/1871). In assessing the relationship between adaptationist and by-product accounts, care must be taken to distinguish several related but importantly different notions: innateness, adaptation, exaptation, spandrel, and (...) by-product.

This article explores the relationship between sexual science and evolutionary models of human development and progress. It examines the ways in which late 19th- and early 20th-century Western European sexual scientists constructed the sexual instinct as an evolutionary force that not only served a reproductive purpose, but was also pivotal to the social, moral, and cultural development of human societies. Sexual scientists challenged the idea that non-reproductive sexualities were necessarily perverse, pathological, or degenerative by linking sexual desire to the evolution (...) of sociality, often focusing on forms of relationality and care that exceeded biological kinship. As a result, non-reproductive sexual expressions, including homosexual and non-reproductive heterosexual behaviours, were interpreted as manifestations of a sexual instinct operating in the service of human development. These claims were reliant on cross-cultural and historical comparisons of sexual values, behaviours, and customs that rehearsed and reinforced imperial narratives of development premised on racialized, gendered, and classed hierarchies. Sexual scientists mapped diverse sexual behaviours in terms of their perceived evolutionary benefits, contributing to colonial narratives that distinguished between different cultures according to imagined trajectories of development. These contestations around the sexual instinct and its developmental functions played a vital role in allowing sexual science to authorize itself as a field of knowledge that promised to provide expertise required to manage sexual life and secure the global development of human civilization.

What is Consciousness For? Lee Pierson and Monroe Trout Copyright © 2005 Abstract: The answer to the title question is, in a word, volition. Our hypothesis is that the ultimate adaptive function of consciousness is to make volitional movement possible. All conscious processes exist to subserve that ultimate function. Thus, we believe that all conscious organisms possess at least some volitional capability. Consciousness makes volitional attention possible; volitional attention, in turn, makes volitional movement possible. There is, as far as we (...) know, no valid theoretical argument that consciousness is needed for any function other than volitional movement and no convincing empirical evidence that consciousness performs any other ultimate function. Consciousness, via volitional action, increases the likelihood that an organism will direct its attention, and ultimately its movements, to whatever is most important for its survival and reproduction.

Progress in neuroscience – notably, on the dynamic functions of neural networks – has deepened our understanding of decision‐making, acquisition of character and temperament, and the development of moral dispositions. The evolution of our cerebral architecture is both genetic and epigenetic: the nervous system develops in continuous interaction with the immediate physical and socio‐cultural environments. Each individual has a unique cerebral identity even in the relative absence of genetic distinction, and the development of this identity is strongly influenced by social (...) and cultural environments leaving major traces in the connectivity of the brain. This interaction introduces important elements of variability and plasticity. Synaptic epigenetic theories of cultural and social imprinting on our brain architecture suggest the possibility that we can be “epigenetically proactive” and adapt our social structures, in both the short and the long term, to benefit and constructively interact with the ever‐developing neuronal architecture of our brains. Epigenetic proaction can be described as a way to socially steer evolution by influencing the cultural imprints to be stored in our brains. The purpose of this article is to present, in a historical and ideological light, the idea that we may culturally shape the developing brain, and discuss some key risks and benefits of this endeavour. The article is a contribution to neuroethics. (shrink)

In evolutionary medicine and other related fields, the concept of evolutionary mismatch is used to explain phenomena whereby traits reduce in adaptive value and eventually become maladaptive as the environment changes. This article argues that there is a similar problem of persistent adaptivity—what has been called the problem of evolutionary novelty—and it introduces the concept of mismatch resistance in order to explain phenomena whereby traits retain their adaptive value in novel environments that are radically different from the organisms’ environment of (...) evolutionary adaptedness (EEA). The possible role of variability selection in the evolution of mismatch-resistant traits is discussed, and it is suggested that mismatch resistance provides a useful tool for making progress on certain issues related to evolutionary theory, such as the modularity debate, cases of adaptivity outside of organisms’ ancestral environment, and the viability of naturalism as an overarching philosophical framework for understanding the natural world.

In this paper I examine various ways in whichphilosophers have made connections between truth andnatural selection. I introduce several versions ofthe view that mechanisms of true belief generationarise as a result of natural selection and argue thatthey fail to establish a connection between truth andnatural selection. I then turn to scientific truthsand argue that evolutionary accounts of the origin ofscientific truth generation mechanisms also fail. Iintroduce David Hull's selectionist model ofscientific development and argue that his account ofscientific success does not (...) rely on connecting truthand natural selection. I argue that Hull's model,which severs the connection between truth andselection, can account for some aspects of scientificchange, but it still leaves us plenty of questionsabout what aspects of our individual cognitive make-upcontribute to scientific change and how they do so. I introduce an evolutionary approach to scientificcognition that shows how some of these questions canbe answered without making an explanatory appeal toselection for true belief generating mechanisms.

Reydon and Scholz raise doubts about the Darwinian status of organizational ecology by arguing that Darwinian principles are not applicable to organizational populations. Although their critique of organizational ecology’s typological essentialism is correct, they go on to reject the Darwinian status of organizational populations. This paper claims that the replicator-interactor distinction raised in modern philosophy of biology but overlooked for discussion by Reydon and Scholz provides a way forward. It is possible to conceptualize evolving Darwinian populations providing that the inheritance (...) mechanism is appropriately specified. By this approach, adaptation and selection are no longer dichotomized, and the evolutionary significance of knowledge transmission is highlighted. (shrink)

Although scholars have paid careful attention to the naturalistic content of the Origin, less focus has been given to Darwin’s strategic deployment of methodological naturalism in the volume. A close inspection shows that he did not use methodological naturalism statically in the six editions of the Origin; instead, he strategically and progressively invoked methodological naturalism in the six editions of the Origin in order to enhance the persuasiveness of his theory and to marginalize special creation from the scientific discussion. In (...) particular, Darwin’s explicit use of methodological naturalism in later editions of the Origin was animated less by epistemic reasons and more by expedient ones. Thus, while Darwin personally may have had sound epistemic grounds for methodological naturalism, his increasing deployment of the method in the Origin seems to have been mainly for the purpose of winning converts to his theory and ostracizing special creation rather than making a strong empirical and philosophical case per se for his position.

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)

Conflict can profoundly affect individuals and their groups. Oftentimes, conflict involves a clash between one side seeking change and increased gains through victory and the other side defending the status quo and protecting against loss and defeat. However, theory and empirical research largely neglected these conflicts between attackers and defenders, and the strategic, social, and psychological consequences of attack and defense remain poorly understood. To fill this void, we model (1) the clashing of attack and defense as games of strategy (...) and reveal that (2) attack benefits from mismatching its target's level of defense, whereas defense benefits from matching the attacker's competitiveness. This suggests that (3) attack recruits neuroendocrine pathways underlying behavioral activation and overconfidence, whereas defense invokes neural networks for behavioral inhibition, vigilant scanning, and hostile attributions; and that (4) people invest less in attack than defense, and attack often fails. Finally, we propose that (5) in intergroup conflict, out-group attack needs institutional arrangements that motivate and coordinate collective action, whereas in-group defense benefits from endogenously emerging in-group identification. We discuss how games of attack and defense may have shaped human capacities for prosociality and aggression, and how third parties can regulate such conflicts and reduce their waste. (shrink)

Darwin thought that the moral sense was among the most challenging aspects of human life to account for through evolutionary explanations. This article seeks to probe the question about human uniqueness primarily from a theological perspective by focusing in depth on one distinctive moral sentiment, gratitude, particularly in the thought of Thomas Aquinas. It uses that example as a case study about how to consider the validity of arguments for human uniqueness within the broader compass of the cultural evolution of (...) sociality and morality within the human sciences, including evolutionary anthropology. Further questions about the evolution of religion surface in this discussion since gratitude, from a theological perspective, necessarily includes gratitude to God as a fundamental aspect of religious faith and practice.

I discuss controversial claims about the status of non-human animals as moral beings in relation to philosophical claims to the contrary. I address questions about the ontology of animals rather than ethical approaches as to how humans need to treat other animals through notions of, for example, animal rights. I explore the evolutionary origins of behavior that can be considered vices or virtues and suggest that Thomas Aquinas is closer to Darwin's view on nonhuman animals than we might suppose. An (...) appreciation of the complexity of the emotional lives of social animals and their cooperative behaviors in light of the work of animal ethologists such as Frans de Waal and Marc Bekoff suggests that social animals can be considered moral in their own terms. I discuss the charge of anthropomorphism, drawing on the work of archaeologist Steven Mithen, and consider arguments for the evolution of conscience in the work of anthropologist Christopher Boehm. Only the biological basis for the development of conscience and religion has evolved in nonhuman animals, and this should not be confused with sophisticated moral systems of analysis or particular religious beliefs found in the human community.

Almost all of the themes contained in E.O.Wilson's sociobiological writing on war and human aggression were prefigured in Anglo-American bio-social discourse, c. 1880–1919. Instinct theory – stemming from animal psychology and the genetics revolution – encouraged the belief that pugnacity had been programmed into the ancient part of the human brain as a result of evolutionary pressures dating from prehistory. War was seen to be instinct-driven, and genocidal fighting postulated as a eugenic force in early human evolution. War was explained (...) in distinctly modern sociobiological terms as adaptive behaviour springing from territorial urges, crowding, competition for resources and reproductive advantage, ethnocentrism and pseudo-speciation.

This paper looks at the neo-Kantian response to Darwinism as a historical science. I distinguish four responses to this aspect of Darwin’s thought from within the neo-Kantian tradition. The first line of response, represented by August Stadler and Bruno Bauch, views Darwin’s model of historical explanation as a fulfilment of Kant’s criteria of scientific intelligibility. The second, represented by Otto Liebmann, regards historical explanation as intrinsically limited, because it cannot tell us why nature develops as it does. The third line (...) of response questions whether we can give a historical account of qualitative change. Friedrich Lange expresses this scepticism in general terms, while Alois Riehl and Ernst Cassirer extend it to human beings specifically. A fourth line of response, represented by Heinrich Rickert, challenges the misperception that Darwinian explanatory principles such as natural selection have normative or socio-political significance.

In his précis of a recent book, Richard Joyce writes, “My contention…is that…any epistemological benefit-of-the-doubt that might have been extended to moral beliefs…will be neutralized by the availability of an empirically confirmed moral genealogy that nowhere…presupposes their truth.” Such reasoning – falling under the heading “Genealogical Debunking Arguments” – is now commonplace. But how might “the availability of an empirically confirmed moral genealogy that nowhere… presupposes” the truth of our moral beliefs “neutralize” whatever “epistemological benefit-of-the-doubt that might have been extended (...) to” them? In this article, I argue that there appears to be no satisfactory answer to this question. The problem is quite general, applying to all arguments with the structure of Genealogical Debunking Arguments aimed at realism about a domain meeting two conditions. The Benacerraf-Field Challenge for mathematical realism affords an important special case. (shrink)

The field of information technology is broadened up to the domain of ‘learning’ systems and cybernetics. In covering this extension of the field due recourse is made to the epistemological basis of theory construction. When so comprehended, information technology becomes a philosophical inquiry on a variety of social, scientific and technological issues. A new idea that we refer to as neuro-cybernetics is born. The term neuro-cybernetics is used to delineate the epistemological field of system and cybernetic study. The above-mentioned phenomenological (...) or the epistemic model of a cybernetic and system type is applied to flood control problem in Bangladesh. This example presents an application of the cybernetic model to a physico-human problem. This is the nature of socio-scientific system. In it, organically unifying relations occur between the environment and the human world, with the objective of controlling the perennial problem of floods by using interactive factors. (shrink)

Sociolinguists study the interaction between language and society. Variationist sociolinguistics — the subfield of sociolinguistics which is the focus of this issue — uses empirical and quantitative methods to study the production and perception of linguistic variation. Linguistic variation refers to how speakers choose between linguistic forms that say the same thing in different ways, with the variants differing in their social meaning. For example, how frequently someone says fishin’ or fishing depends on a number of factors, such as the (...) speaker's regional and social background and the formality of the speech event. Likewise, if listeners are asked to use a rating scale make judgements about speakers who say fishin’ or fishing, their ratings depend on what other social characteristics are attributed to the speaker. This issue aims to reflect the growing number of interactions that bring variationist sociolinguistics into contact of different branches of cognitive science. After presenting current trends in sociolinguistics, we identify five areas of contact between the two fields: cognitive sociolinguistics, sociolinguistic cognition, acquisition of variation, computational modeling, and a comparative approach of variation in animal communication. We then explain the benefits of interdisciplinary work: fostering the study of variability and cultural diversity in cognition; bringing together data and modeling; understanding the cognitive mechanisms through which sociolinguistic variation is processed; examining indexical meaning; exploring links between different levels of grammar; and improving methods of data collection and analysis. Finally we explain how the articles in this issue contribute to each of these benefits. We conclude by suggesting that sociolinguistics holds a strategic position for facing the challenge of building theories of language through integrating its linguistic, cognitive, and social aspects at the collective and individual levels.

Preston & de Waal are understandably cautious in applying their model to autism. They emphasise multiple cognitive impairments in autism, including prefrontal-executive, cerebellar-attention, and amygdala-emotion recognition deficits. Further empirical examination of imitation ability in autism may reveal deficits in the neural and cognitive basis of perception-action mapping that have a specific relation to the empathic deficit.

In the past 150 years there have been many attempts to draw parallels between cultural and biological evolution. Most of these attempts were flawed due to lack of knowledge and false ideas about evolution. In recent decades these shortcomings have been cleared away, thus triggering a renewed interest in the subject. This paper offers a critical survey of the main issues and arguments in that discussion. The paper starts with an explication of the Darwinian algorithm of evolution. It is argued (...) that this ‘formula’ is substrate-neutral, which means that biological evolution might not be the only Darwinian process. Other dynamic systems could evolve as well provided that certain conditions are met. In the case of human culture this seems to be the case. The paper then focuses on the notion of niche construction. It is argued that niche construction plays a crucial role in human evolution because it has altered the sources of natural selection and thus the path of evolution. Next two approaches to cultural evolution are discussed: sociobiology and memetics. I will argue that both approaches have flaws because they either underestimate the influence of culture or they stretch analogies too far. Finally two common objections against the idea of cultural evolution are addressed: Lamarckian inheritance and the issue of guided variation. I will argue that although cultural evolution differs from biological evolution in several respects, these discrepancies do not jeopardize the claim that cultural evolution is essentially Darwinian.

In recent years many historical myths about the relations between science and religion have been corrected but not always with sensitivity to different types and functions of “myth.” Correcting caricatures of Darwin's religious views and of the religious reaction to his theory have featured prominently in this myth‐busting. With the appearance in 2017 of A. N. Wilson's depiction of Darwin himself as a “mythmaker,” it is appropriate to reconsider where the myths lie in discourse concerning Darwin and Christianity. Problems with (...) Wilson's account are identified and his provocative demeaning of Darwin is contrasted with an image gleaned from Darwin's friend and colleague George Romanes. The article concludes with a brief reference to the problem of suffering and to the work of Christopher Southgate. (shrink)

Abstract This investigation considers a number of approaches to the definition and analysis of ?culture?. It shows that although approaches to culture span a wide range of viewpoints, there are gems that can be distilled and developed. To that end, a definition of ?culture? is proposed that it is contended captures much of the positive character in what has preceded it and hopefully avoids the negative. This is followed by a discussion of some of the most important studies concerned with (...) the evolution of culture and the notions of culture that constitute the fulcrum of these investigations. Here we find almost as many approaches as there are proponents. However one stands out, of those surveyed here, as being of potentially greatest value to social scientists, the dual inheritance theory of Boyd and Richerson (1985). (shrink)

Humans grasp discrete infinities within several cognitive domains, such as in language, thought, social cognition and tool-making. It is sometimes suggested that any such generative ability is based on a computational system processing hierarchical and recursive mental representations. One view concerning such generativity has been that each of the mind’s modules defining a cognitive domain implements its own recursive computational system. In this paper recent evidence to the contrary is reviewed and it is proposed that there is only one supramodal (...) computational system with recursion in the human mind. A recursion thesis is defined, according to which the hominin cognitive evolution is constituted by a recent punctuated genetic mutation that installed the general, supramodal capacity for recursion into the human nervous system on top of the existing, evolutionarily older cognitive structures, and it is argued on the basis of empirical evidence and theoretical considerations that the recursion thesis constitutes a plausible research program for cognitive science.

Computer simulations can be useful tools to support philosophers in validating their theories, especially when these theories concern phenomena showing nontrivial dynamics. Such theories are usually informal, whilst for computer simulation a formally described model is needed. In this paper, a methodology is proposed to gradually formalise philosophical theories in terms of logically formalised dynamic properties. One outcome of this process is an executable logic-based temporal specification, which within a dedicated software environment can be used as a simulation model to (...) perform simulations. This specification provides a logical formalisation at the lowest aggregation level of the basic mechanisms underlying a process. In addition, dynamic properties at a higher aggregation level that may emerge from the mechanisms specified by the lower level properties, can be specified. Software tools are available to support specification, and to automatically check such higher level properties against the lower level properties and against generated simulation traces. As an illustration, three case studies are discussed showing successful applications of the approach to formalise and analyse, among others, Clark’s theory on extended mind, Damasio’s theory on core consciousness, and Dennett’s perspective on intertemporal decision making and altruism.

This opens space for contemplating separability and determinacy as ontological difficulties contributing to socio-ecological crises of our time.

Ever since proposals for generalizing the theory of natural evolution have been put forward, the aims and ambitions of both proponents and critics have differed widely. Some consider such proposals as merely metaphors, some as analogies, some aim at a real generalization and unification, and some have even proposed to work out full reductions. In this paper it is argued that these different forms of generalizing the theory of evolution can be systematically re-framed as different approaches for transferring justification from (...) the natural to the cultural realm, and that their differences are basically a matter of degree. With the help of such a classification it should become clearer what to expect, but also what not to expect from the different approaches. (shrink)

Human aesthetic preferences towards a certain landscape type, a certain bodily traits of the opposite sex, a figurative style rather than another, are embedded in what we call “aesthetic experience”, a complex network of instinctive reactions, emotions, feelings, thoughts, and judgements. Are these preferences universal and species-specific, that is to say are they the same for every member of a particular species? Evolutionary psychologists advocate the universality and species-specificity of the aesthetic preferences. Going back to Darwin's writings, in particular to (...) his Notebooks, Bartalesi and Portera attempt to provide an alternative explanation for the emergence and development of human aesthetic preferences, beyond the dichotomy of nature and culture.
