In recent years, the explanatory term “scaffold” has been gaining prominence in evolutionary biology. This notion has a long history in other areas, in particular, developmental psychology. In this paper, we connect these two traditions and identify a specific type of explanatory strategy shared between them, namely scaffolding explanations. We offer a new definition of “scaffold” anchored in the explanatory practices of evolutionary biologists and developmental psychologists that has yet to be clearly articulated. We conclude by offering a systematic overview (...) of the various dimensions of scaffolding explanations that further suggests both their usefulness and range of application. (shrink)

Spillover occurs when one environmentally sustainable behaviour leads to another, often initiated by a behaviour change intervention. A number of studies have investigated positive and negative spillover effects, but empirical evidence is mixed, showing evidence for both positive and negative spillover effects, and lack of spillover altogether. Environmental identity has been identified as an influential factor for spillover effects. Building on identity process theory the current framework proposes that positive, negative, and a lack of spillover are determined by perceived threat (...) of initial behaviour and identity process mechanisms evaluating the behaviour. It is proposed, that an environmental behaviour change intervention may threaten one’s existing identities, leading to either (a) integration, (b) compartmentalisation, or (c) conflict between one’s environmental identity and non-environmental identities. Initial evidence for the proposed framework is based on a field intervention which included a meat reduction programme in a canteen of a medium size private sector company. Semi-structured interviews and an explorative visualisation method that aimed at assessing identity change were implemented with thirteen employees (i.e. intervention participants) before and after the intervention. The qualitative data was analysed by using thematic analysis via NVivo12. Results of the visualisation task and interview method provided initial evidence of direct and indirect positive contextual spillover effects, with comparatively less evidence a lack of spillover and a relative absence of reported negative spillover. This paper provides a novel theoretical approach, centred on identity process theory to enhance understanding of positive spillover, negative spillover, and the lack of spillover. (shrink)

The issue of free will is a complex one that has occupied the minds of many theologians and philosophers through the ages. The two main aspects of free will are the freedom to do otherwise and the power of self-determination. This means that an agent must be able to choose from alternative possibilities and that he or she must be the author or source of that choice. Defined as such, it is clear that the issue of free will is undeniably (...) closely linked with the concept of moral responsibility. However, if we live in a deterministic world, where everything is governed by the laws of nature, including our thoughts and behaviour, does this leave room for free will and moral responsibility? As Dutch neurobiologist and author Dick Swaab argues, the answer is an emphatic ‘no’. In this article, we will look at Swaab’s case against free will. We will also see what modern neuroscience has to say about this hot topic and whether it supports or discredits Swaab’s views. And finally, we will touch on what this all means for moral responsibility. Contribution: This article is part of a special collection that reflects on the evolutionary building blocks of our past, present and future. It is based on historical thought and contemporary research. It fits well with the intersectional and inter-disciplinary nature of this collection and journal. (shrink)

In this article, focusing on the building blocks of art with its concomitant role and meaning, we commence with a brief evolutionary overview of the origin of land vertebrates, which culminated in the rise of our species as we view it. We then review three iconic phases of human evolution, colloquially designated as the Neanderthals, the San and the Cro-Magnons, as manifested by their artistic endeavours. We are well aware that the Cro-Magnons are currently regarded as not sufficiently distinct from (...) modern Homo sapiens to be separately designated. Therefore, the terms ‘anatomically modern humans’ or ‘early modern humans’ are suggested for these inhabitants of the Upper Palaeolithic as they shared an anatomical resemblance with us but still lacked the full complement of behavioural attributes that typify ourselves. This particular selection was chosen because these groups have partially overlapped historically, yet each represents a distinctive approach to the artistic impulse. Subsequently, we consider more contemporary developments regarding human art intertwined with our interpretation of art’s role and meaning. Then, we briefly discuss a broader account of the evolution of art in which these three phases are firmly based and through which our understanding of and engagement with the evolutionary development of these stages are elucidated and complemented. In conclusion, particular views about language and the role and meaning of art are confirmed. Particular views about language and the role and meaning of art are endorsed and supplemented by an extensive body of relevant literature.Contribution: This article explores the evolution of art and its accompanying role and meaning in an intersectional and interdisciplinary manner that fits well with the intention of this unique collection on the building blocks of our past, present and future and with the nature of this journal and our ongoing engagement with HTS Teologiese Studies/Theological Studies.

The origins of agriculture lie in the distant past, approximately 12 000 years ago, when hunter-gatherers of the Palaeolithic embraced sedentism at the dawn of the Neolithic. The variety of life history transitions emanating from this unique phenomenon have had an enormous impact on the biodiversity of the planet, while subjecting humanity to a variety of life-changing physical and social challenges right up to the present. The ever-present consequences of the Agricultural Revolution continue to demand our attention, yet frustrate our (...) efforts, on a seemingly perpetual basis, to effectively manage the outcomes. Here we review the origins and lasting after-effects of the Agricultural Revolution and its impact on the human condition, with reference to sedentism, nutrition, health issues, disease, gender discrimination as well as mythmaking and religion. Contribution: Our aim is to engage a wider audience with respect to the causes and consequences of the Agricultural Revolution. We discuss a broad spectrum of relevant phenomena implicated in this epochal event and consequently underline that the Agricultural Revolution precipitated not only major changes to the ecology of the planet, but also and most importantly to the social and cultural well-being of humanity.

The early Nishida has conventionally been seen as an apolitical thinker, concerned primarily with religious philosophy. In itself this constitutes a political reading of Nishida's work, since it represents an attempt to distance (and thus "save") his wider philosophy from his dubious political practice during the 1930s and 1940s. However, a fresh reading of Nishida's debut, "Zen no kenkyū" (An inquiry into the good), reveals a distinctive political agenda and a sophisticated philosophy of political ethics. Counterintuitively, this essay suggests that (...) Nishida's politics, at least in his "early period," provides a sound philosophical basis for a critique of imperialism and ultranationalism.

Two or more independent species lineages can fuse through an evolutionary transition to form a single lineage, such as in the case of eukaryotic cells, lichens, and coral. The fusion of two or more independent lineages requires intermediary steps of increasing selective interdependence between these lineages. We argue a precursory selective regime of such a transition can be Multilevel Selection 1 (MLS1). We propose that intraspecies MLS1 can be extended to ecological multispecies arrangements. We develop a trait group selection (MLS1) (...) model applicable to multispecies mutualistic interactions. We then explore conditions under which such a model could apply to mutualistic relationships between pollinators and plants. We propose that MLS1 could drive transitions towards higher interdependency between mutualists and stabilise obligate mutualisms in the face of invasion by cheater variants. This represents a radical extension of multilevel selection theory, applying it to the evolution of multispecies populations, and indicating new avenues for researching ecological community evolution.

In the human context, the ubiquitous faculty of imagination is taken for granted. Whether we are singularly equipped with this ability or whether it is an evolved faculty also present in other life forms is a question that has been an issue ever since Darwin. A variety of research projects have indicated the presence of mental processes in non-human taxa and the faculty of imagination developed with increasing complexity over time, to its present status in humans. As an evolved faculty, (...) encompassing a variety of non-humans, it serves as a useful tool to ascertain and understand the origins and unique quality of human mental processes, even to the extent of informing certain medical issues and problems in education. Several pointers exist that argue for human imagination as an evolved faculty that is shared within broad spectrum of taxa. Paleoanthropological research has provided insights as to the role of imagination in the early manifestations of religious behaviour in humans, the construction of effective stone tools by anatomically modern humans employing pyro technology, as well as their ability to mentally link ostensibly non-related natural phenomena like tidal fluctuations and the phases of the moon. Contribution: This review article explores imagination as an evolved faculty in an intersectional and interdisciplinary manner. This evolutionary reflection fits well with the purpose and inclusive nature of this special collection on the building blocks of our past, present and future. (shrink)

In Libanius' speech For the Temples, sometimes regarded as the crowning work of his career, he refers to an unnamed city in which a great pagan temple had recently been destroyed; the date of the speech is disputed, but must be in the 380 s or early 390 s, near the end of the speaker's life. After deploring the actions of a governor appointed by Theodosius, often identified with the praetorian prefect Maternus Cynegius, Libanius continues : Let no-one think that (...) all this is an accusation against you, Your Majesty. For on the frontier with Persia there lies in ruins a temple which had no equal, as one may hear from all who saw it, so very large was it and so very large the blocks with which it was built, and it occupied as much space as the city itself. Why, amid the terrors of war, to the benefit of the city's inhabitants, those who took the city gained nothing because of their inability to take the temple as well, since the strength of the walls defied every siege-engine. Besides that, one could mount up to the roof and see a very great part of enemy territory, which gives no small advantage in time of war. I have heard some people disputing which of the two sanctuaries was the greater marvel, this one that has gone, or one that one hopes may never suffer in the same way, and contains Sarapis. But this sanctuary, of such a kind and size, not to mention the secret devices of the ceiling and all the sacred statues made of iron that were hidden in darkness, escaping the sun – it has vanished and is destroyed. Jacques Godefroy, best known for his edition of the Theodosian Code, also produced the editio princeps of the speech For the Temples, supplying a Latin translation and extensive notes. He hesitated whether to identify the city in question with Apamea in Syria or with Carrhae, ‘urbs superstitione Gentilicia tum referta’, but opted for a third choice: Edessa, the capital of Osrhoene. In doing so he took for granted that a law of the Theodosian Code, in which the emperors order that a pagan temple in Osrhoene remain open, referred to the same temple; I shall argue below that this is incorrect. Opinion continues to be divided, though with a majority favouring Edessa. But this lay some ten or fifteen miles from the border with Persia, whereas Carrhae was directly on it, and is much more likely than Edessa to have had a temple from which one ‘could observe a vast area of enemy country’. The principal deity of Carrhae was Sîn, the Moon God, said by some sources to be male, by others to be female. Describing how Caracalla was assassinated while on a pilgrimage to the god, Cassius Dio says that he had ‘set out from Edessa for Carrhae’, and was murdered on the way: according to Herodian, he was staying in Carrhae when he decided to go in advance of his army ‘and to reach the temple of the Moon, whom the local people greatly revere: the temple is a long way from the city [presumably Carrhae], so as to require a journey’. Another emperor to visit the sanctuary was Julian on his march into Babylonia. Theodoret of Cyrrhus alleges that ‘he entered the sanctuary honoured by the impious’ and cut open a human victim, a woman suspended by the hair, in order to obtain an omen of his future victory.

The subject of “the last pagans” or “the end of paganism” in the Greco-Roman world has interested scholars for over a century but begs the question “What is paganism?” Is the term usable as a tool of analysis? It originates from the Latin paganus, meaning “villager,” “rustic,” and reflects the way that Latin speakers viewed early Christianity as a phenomenon of the countryside, much as the English heathen, or German Heide, derives from a root meaning “heath.” Greek-speaking Christians, by contrast, (...) used a variety of terms, but their favored one was Hellene, which reflected the perception that their main opposition came from Greeks who remained faithful to their traditional culture and beliefs. Hence paganism, when used by a modern author, is implicitly one-sided and also obscures the very real gap in perception between Greek speakers and Latin speakers of antiquity. Accordingly, some recent authors have tried to replace pagan with polytheist, but the latter term has the disadvantage that many pagans tended toward monotheism, or to a modified monotheism that regarded one god as vastly superior to all others (“henotheism”). Heathen is similar in being an insider's term, current when Christianity was the default position of religious discourse, and now largely obsolete. It is best to retain the word pagan but to concede that it is merely a pis aller. (shrink)

Ever since Clifford Geertz urged the “blurring of genres” in the social sciences, many scholars have considered the crossing of disciplinary boundaries a healthy alternative to rigidly maintaining them. But what precisely does the metaphor of “blurring” imply? By unpacking the varieties of visual experiences that are normally grouped under this rubric, this essay seeks to provide some precision to our understanding of the implications of fuzziness. It extrapolates from the blurring caused by differential focal distances, velocities of objects in (...) the visual field, and competing perspectival vantage points to comparable effects in the intersection of different scholarly disciplines. Arguing against the holistic implications of Geertz's metaphor, as well as the even more totalizing concept of “consilience” introduced by E. O. Wilson, it suggests that blurring implies new types of complexity between or among those disciplines. (shrink)

Articulate language is a form of communication unique to humans. Over time, a spectrum of researchers has proposed various frameworks attempting to explain the evolutionary acquisition of this distinctive human attribute, some deploring the apparent lack of direct evidence elucidating the phenomenon, whilst others have pointed to the contributions of palaeoanthropology, the social brain hypothesis and the fact that even amongst contemporary humans, social group sizes reflect brain size. Theologians have traditionally ignored evolutionary insights as an explanatory paradigm for the (...) origin of humankind. However, an increasing number are, of late, contributing to a worldview of humanity which accommodates both the epistemological realities of evolutionary biology as well as insights from theology. This includes reviewing and assessing the origins of articulate language and the physiological attributes necessary for its development. It is in this sense that the evolution of language is relevant from a theological perspective. The association between mental capacity and articulate language, already noted by Darwin, is relevant in explaining the larger group sizes found amongst humans, as is the incipient role played by the evolution of laughter in triggering the neuroendocrine system promoting bonding, to the eventual development of articulate language. Our aim is to review a selection of contemporary perspectives on the evolution of language, amongst others, reasons for the ease with which young children acquire language competency, and whether we may be hardwired for language from birth. Further reading is suggested in the footnotes.Contribution: This article is part of a special collection reflecting on the evolutionary building blocks of our past, present and future. It is based on historical thought and contemporary research with regards to the evolutionary emergence of language. It fits well with the intersectional and trans-disciplinary nature of this collection and journal. (shrink)

In the light of requests from certain civil organisations in the Western Cape to the provincial government to establish a judicial commission of inquiry into child killings in this province because of the high incidence of killings, a research committee from three WC universities was put together to review existing research into this matter to determine a way forward. This committee looked at primary drivers of child murders in the WC, gaps in existing government services, the potential value of instigating (...) a commission of inquiry or some other mechanism, and recommending a way forward. A summary of its findings was presented to, among others, the provincial cabinet that adopted all its recommendations. Reflection on these final findings and recommendations forms the first part of the article. The second part focuses in more detail on the research data presented by experts and practitioners who informed the research committee. Important aspects discussed here are child death reviews, age- and sex-specific rates of child homicides, sexual killings of children, the possible influence of unfortunate, traumatic childhood experiences in becoming a violent adult, physical violence against children, children’s perception of their safety and risk factors for children specifically in the WC. The purpose of this article is to provide well-researched information to role-players and decision-makers regarding the lives of children to address the violence and its causes that so many children are exposed to. Although the focus is on the dire situation in the WC, the broader South African and international contexts will also be brought into play in the second part of the article in a way that will be helpful with regard to the crises and challenges the WC is struggling with in this respect.

This essay focuses on determining moral leadership, as theoretically debated from an evolutionary point of view in an attempt to reflect on how this kind of moral leadership can contribute, among others, in dealing with issues such as gender, race, poverty and sexual orientation. Although important, not one of the latter issues will be discussed. It is not the primary focus of the essay. But because we are aware of the extent of the challenges regarding these issues, they were specifically (...) identified as examples for applying the moral guidelines developed and determined in this essay. This essay mainly argues that morality and moral leadership require analytical and critical evolutionary thinking and reflection that could contribute to making the world a more just and fair place in which to live. Moral leaders are created when people are constantly striving in an ongoing process of reasoning to become more humane, thereby allowing every person to flourish and to reach their full potential through biologically determined and justice-based moral reflection and action.

Herodotus has often been considered the Father of Ethnography no less than the Father of History. It comes as a paradox, then, that he has been taxed with confusion in his use of two terms that recur over and over in his discussion of peoples, ἕθνος and γνος. Here is the formulation of Raymond Weil:Hérodote definit mal l‘ethnos’. C'est pour lui tantôot une subdivision du ‘génos’, tantôt au contraire un ensemble de ‘géné’. Ainsi 1' ‘ethnos’ des Médes, comme celui des (...) Scythes, groupe plusieurs γνεα. Mais cet ‘ethnos’ scythe porte aussi le nom de ‘génos’, et comprend des ἕθνεα. Les Athéniens sont un ‘ethnos’ hellénique qui fait partie du ‘génos’ ionien, les Lacédémoniens un ‘ethnos’ pélasgique à rattacher au ‘génos’ dorien. (shrink)

The interaction between the concepts of character attachment, agency, and choice in a video game narrative was investigated using BioWare’s Mass Effect trilogy. Posts on a BioWare forum discussing the depiction of their player characters in the ending sequences of Mass Effect 3, the final game in the trilogy, were downloaded and analyzed using thematic analysis. Players demonstrated emotional attachment for the characters and narrative and expected to see the consequences of their choices play out, as in the previous games. (...) Furthermore, players conflated winning the game with achieving a narratively satisfactory ending for the game world and its characters indicating emotional consequences for players that developers should consider when designing games with a high degree of player choice and agency. However, for some players character attachment is incongruous as they described Shepard as “acting out of character,” which needs further research. (shrink)

The book reflects academically on important and relevant ethical fields from a multidimensional South African context. The book challenges conventional borders from different ethical, theological, philosophical, economic and cultural perspectives with insight and expertise and seeks to add academic-ethical value, locally and globally, with its different points of departure deeply embedded in justice. From a mainly qualitative methodological perspective, this scholarly book demonstrates that ethics requires analytical thinking and critical people who, in an existentially and emancipatory way, can help make (...) the world a more just, decent and humane place in which to live. The authors, who represent different academic and cultural backgrounds, present in their respective chapters their research systematically, intersectionally and constructivistically, based on profound theoretical analysis and reasoning. This epistemology results in an act of knowing that actively gives meaning and order to the reality to which it is responding. By doing this, they point out that people are in an ongoing process of becoming more human – allowing ourselves and our fellow human beings to flourish and to reach fuller potential through justice-based ethical reflection and action.

The aim of this article is to construct an analogy between the synaptic gap and mediated experience. In the brain sciences, the synaptic gap is defined as the space between neurons, a divide across which the activity of the brain is conducted. Research findings suggest that the network of synaptic gaps in the brain best describes the locus of the mind. Mediated experience denotes a perceptual experience made possible by technology, in which a phenomenon is perceived through a representation that (...) has been transmitted as information across a network. The transmission of representational information across a divide is the crux of the analogy between mediated experience and the synaptic gap. Cybernetics, media theory, information theory and postmodern theory have all explored various inferences that follow from the structural resemblance between neural networks and communications media networks. In the arts, theorists have described a networked global brain and posited the emergence of a collective consciousness. In general, these theories are not widely accepted. This article concludes that these theories might be reframed in the light of a recent distinction provided by cognitive science between consciousness and mind. While it is unlikely that networked mediated experience gives rise to a collective consciousness, it may well constitute aspects of an externalization of a collective mind. (shrink)

This paper discusses the background in reality of the Heroikos (Dialogue concerning Heroes), which is ascribed to Philostratus of Athens, and is mainly devoted to the hero Protesilaos. After a summary of the work, the paper considers it from four aspects. The time of writing falls after 217 (the second victory at Olympia of the athlete Helix of Phoenicia); there may be a reference to events in Thessaly under the emperor Alexander Severus (222-235). If the author is the well-known Philostratus, (...) then such a date also implies a dramatic date in the author¿s own time. This is corroborated by two series of references which appear to run from the comparatively recent past to the present. One of these concerns bones of heroes, while the other concerns athletes to whom the hero Protesilaos had given advice in the form of oracles. The geographical setting of the dialogue is Elaious in the Thracian Chersonese. The evidence for the cult of Protesilaos on the territory of Elaious comes from literature, notably Herodotus, from coins of the time of Commodus, and from modern observations, notably a vivid account given by Heinrich Schliemann. While Philostratus¿ description of the cult-place at Elaious appears very accurate, his account of the Island of Achilles in the Pontus is less so. Finally, the paper considers the Heroikos in the context of contemporary belief about heroes and their powers. Another work probably by the same author, the Life of Apollonius of Tyana, is adduced to assess the credulity of readers in Philostratus¿ time and later. Documents and literature of the imperial period show that even dead contemporaries could be regarded as heroes, who were still influential even from beyond the grave. The references to Protesilaos in literature (Pausanias, Lucian) strongly suggest that he was regarded as issuing oracles in the form of dreams, and this too accords with beliefs about heroes both in the Hellenistic period and in the Roman.

This paper examines several philosophical issues related to emerging technologies in sport and leisure. There are a range of technologies that will likely be offered to boost performance in sport, ranging from prosthetic devices and cyborg-like implants to gene therapy and enhancement. Computer generated simulations are already in use in work and leisure, and are expected to be pervasive in the future. Technological developments such as these present a challenge to some of the traditional assumptions and cherished beliefs not only (...) about the nature of sport and leisure and how they should be conducted, but also about the very nature of reality and what it means to be human. It is hoped that this paper can shed some light on the challenges and possibilities facing sport and leisure in the upcoming high-tech future. (shrink)

This collection of essays, written by leading experts, showcases historiographical problems, fresh interpretations, and new debates in medieval and Renaissance history and political thought. Recent scholarship on medieval and Renaissance political thought is witness to tectonic movements. These involve quiet, yet considerable, re-evaluations of key thinkers such as Thomas Aquinas and Machiavelli, as well as the string of lesser known "political thinkers" who wrote in western Europe between Late Antiquity and the Reformation. Taking stock of thirty years of developments, this (...) volume demonstrates the contemporary vibrancy of the history of medieval and Renaissance political thought. By both celebrating and challenging the perspectives of a generation of scholars, notably Cary J. Nederman, it offers refreshing new assessments. The book re-introduces the history of western political thought in the Middle Ages and the Renaissance to the wider disciplines of History and Political Science. Recent historiographical debates have revolutionized discussion of whether or not there was an "Aristotelian revolution" in the thirteenth century. Thinkers such as Machiavelli and Marsilius of Padua are read in new ways; less well-known texts, such as the Irish On the Twelve Abuses of the Age, offer new perspectives. Further, the collection argues that medieval political ideas contain important lessons for the study of concepts of contemporary interest such as toleration. The volume is an ideal resource for both students and scholars interested in medieval and Renaissance history as well as the history of political thought. (shrink)
