This paper inquires into the nature of intertheoretic relations between psychology and neuroscience. This relationship has been characterized by some as one in which psychological explanations eventually will fall away as otiose, overthrown completely by neurobiological ones. Against this view it will be argued that it squares poorly with scientific practices and empirical developments in the cognitive neurosciences. We analyse a case from research on visual perception, which suggests a much more subtle and complex interplay between psychology and neuroscience than (...) a complete take-over of the former by the latter. In the case of vision, cross-theory influences between psychology and neuroscience go back and forth, resulting in refinement in both disciplines.We interpret this case study as showing that:(1) Mutual co-evolution of psychological and neurobiological theories, exemplifying persisting top-down influences from psychology, is a more empirically adequate way to describe psychoneural theory relations than a view on co-evolution, favoured by reductionists, which regards the cross-theory contributions from psychology as merely heuristically useful with no enduring influence on neurobiological theorizing;(2) In research on vision, discovering (or hypothesizing) the neural basis of functions vindicates psychological approaches, it does not eliminate them;(3) Current work on vision shows that many perceptual phenomena must be understood in terms of dynamical interactions between an observer and his/her environment. Therefore, we argue that internalist characterizations of the visual system must be supplemented with externalist accounts that address these reciprocal observer-environment interactions involved in vision. Such processes seem quite different from (internal) cellular and molecular ones, and as such seem to lie outside the scope of neuroscientific inquiry. We conclude that psychoneural reduction or elimination is implausible as a meta-theoretical prediction of theory choice in empirical work. Instead, this case study of vision shows that both psychology and neuroscience contribute to, and complement one another in the study of visual perception. 1.

The concept of technical function is a key concept to describe technical artifacts and artifacts-to-be-designed. Engineers often give such descriptions in terms of functional decomposition models, which represent relationships between functions and sets of other functions. Despite the importance of the concept of function there is no consensus among engineers about its meaning. Models of functional decomposition are likewise conceptually divergent. Although this conceptual diversity hampers information exchange between engineers, they accept and maintain it. Engineers do not, by and large, (...) engage in a focused debate to establish commonly shared functional conceptualizations. This contrasts with science where both debates on the adequacy of key conceptualizations and convergence toward shared conceptualizations are common. This book investigates the side-by-side usage of different functional decomposition models in engineering. It explains this phenomenon by applying and extending the analysis of theory choice in terms of methodological incommensurability to engineering functional decomposition, rather than to science. This analysis shows that engineers’ usage of competing functional decomposition models is rational from a practical point of view. This book furthermore investigates the communication problems that the side-by-side usage of different models engenders and presents a strategy that supports the exchange and re-use of functional information between engineers.

In this paper I address the current debate on ontic versus epistemic conceptualizations of mechanistic explanation in the mechanisms literature. Illari recently argued that good explanations are subject to both ontic and epistemic constraints: they must describe mechanisms in the world in such fashion that they provide understanding of their workings. Elaborating upon Illari’s ‘integration’ account, I argue that causal role function discovery of mechanisms and their components is an epistemic prerequisite for achieving these two aims. This analysis extends Illari’s (...) account in important ways, putting more pressure on ontic readings of mechanistic explanation and providing an answer to the question how ontic and epistemic constraints on mechanistic explanation are related. I argue these point in terms of cases on memory research drawn from neuroscience and research on extinct neurogenetic mechanisms from early nervous systems biology. (shrink)

What features will something have if it counts as an explanation? And will something count as an explanation if it has those features? In the second half of the 20th century, philosophers of science set for themselves the task of answering such questions, just as a priori conceptual analysis was generally falling out of favor. And as it did, most philosophers of science just moved on to more manageable questions about the varieties of explanation and discipline-specific scientific explanation. Often, such (...) shifts are sound strategies for problem-solving. But leaving fallow certain basic conceptual issues can also result in foundational debates. (shrink)

Many readings of the Parable of the Labourers in the vineyard want to treat the owner as representing God. Knowledge of actual agricultural practices relating to the management of vineyards suggest, on the contrary, that the details of the parable obstruct an easy identification of the owner with God, and that he displays unusual behaviour not only by paying all the labourers the same wage, but by his very intervention in the hiring process. The conclusion reached is that the parable (...) constructs the vineyard owner, typically one of the nouveau riche who lived in cities, not only as a ‘good employer’ but also, contrary to expectation, as a patron who intervened well beyond the strict norms of economic exchange.

In this paper we investigate how inference to the best explanation (IBE) works in engineering science, focussing on the context of malfunction explanation. While IBE has gotten a lot of attention in the philosophy of science literature, few, if any, philosophical work has focussed on IBE in engineering science practice. We first show that IBE in engineering science has a similar structure as IBE in other scientific domains in the sense that in both settings IBE hinges on the weighing of (...) explanatory virtues. We then proceed to show that, due to the intimate connection between explanation and redesign in engineering science, there is a further engineering domain-specific virtue in terms of which engineering malfunction explanations are evaluated, viz. the virtue of redesign utility. This virtue entails that the explanatory information offered by a malfunction explanation should be instrumental in predicting counterfactual dependencies in redesigned systems. We illustrate and elaborate these points in terms of a number of engineering examples, focussing in particular on the 2009 crash of Air France Flight 447. Our extension of analyses of IBE and explanation to engineering science practice offers new insights by identifying a new explanatory virtue in malfunction explanation: redesign utility. (shrink)

This article seeks to interpret the phrase Πάτερ, ημων ο εν τοῖς οὐρανοῖς in the invocation of the Lord’s Prayer in the light of Ewe-Ghanaian cosmology. The article employs a combination of the historical-critical and indigenous mother tongue biblical hermeneutical approaches to explore the implication of the invocation for Ewe-Ghanaian Christian spirituality today. The article firstly discusses the various theological and hermeneutical positions of the invocation in dialogue with Ewe-Ghanaian concept of God and the plurality of his dwelling place. The (...) article argues that Matthew’s use of οὐρανοῖς to suggest a plurality in God’s dwelling place resonates with Ewe cosmology, where it is believed that there are seven states of existence and that Mawugã, the Supreme Being, dwells in the first – the absolute state. Thus God exists in ‘seven heavens’ in Ewe cosmology, with the highest heaven being the eternal state of abode. On the other hand, the inclusive interpretation of the fatherhood of God in Ewe cosmology is discontinuous with the exclusive interpretation in the works of the church fathers such as Cyprian, Origen, Gregory of Nissa, Augustine and Clement of Alexandria. This hermeneutical position, the article observes, was responsible for the theological tensions that characterised the encounter between missionary Christianity and Ewe indigenous religion in the middle of the 19th century. However, the introduction of social services as evangelisation strategy, the legacy of the Ewe Bible and liturgy and the handing over of the Ewe church to the indigenous coworkers may have contributed to a large extent in ensuring religious tolerance among followers of the two religions. Today, Ewe-Ghanaian popular Christianity has shifted from its apologetic stance to a more liberal stance and employs indigenous religious and cultural categories in theologising.Contribution: Matthew’s rendition of the invocation of the Lord’s Prayer in the context of Ewe-Ghanaian cosmology is the focus of this article. The article forms part of the researcher’s contribution to the academic knowledge on the Lord’s Prayer and inspires the use of mother tongue biblical hermeneutics in the development of theological materials for the Ewe-Ghanaian Christian communities in Ghana and Togo.

This article presents a narratological reading of the Gospel of Mark with special attention given to the role, function and rhetorical impact of point of view. It is argued that through the use of ‘witnesses’ ranging from the omniscient narrator, to the character God, to the Old Testament Scriptures, the author of Mark presents a point of view that his implied reader would find difficult to counter. In addition to this, the article demonstrates that the motifs of allegiance, misunderstanding and (...) opposition in the Second Gospel are almost entirely confined to the adoption or rejection of the point of view being advocated for by the author of Mark. In the end, it is shown that only in the death of Jesus on the cross and the subsequent ‘centurion’s confession’ are the motifs resolved and is the point of view of Mark accepted by a human character.

In this paper we chart epistemological similarities between shared function talk in biology and the engineering sciences, focusing on the notions of biological advantage function and technical advantage function. We start by showing that biological advantage function ascriptions are common in biology and that technical advantage function ascriptions are common in engineering science. We then proceed to show that these ascriptions have a very similar structure and that their epistemic value also is similar: both biological advantage function and technical advantage (...) function ascriptions provide the means to answer what-would-happen-if questions. We develop and illustrate our claims with four case studies: two from biology, and two from engineering design research. Our results offer new insights into a relatively neglected issue in both philosophy of biology and technology, viz. assessing the explanatory and predictive utility of function ascriptions. (shrink)

Our lives are increasingly intertwined with the digital realm, and with new technology, new ethical problems emerge. The academic field that addresses these problems—which we tentatively call ‘digital ethics’—can be an important intellectual resource for policy making and regulation. This is why it is important to understand how the new ethical challenges of a digital society are being met by academic research. We have undertaken a scientometric analysis to arrive at a better understanding of the nature, scope and dynamics of (...) the field of digital ethics. Our approach in this paper shows how the field of digital ethics is distributed over various academic disciplines. By first having experts select a collection of keywords central to digital ethics, we have generated a dataset of articles discussing these issues. This approach allows us to generate a scientometric visualisation of the field of digital ethics, without being constrained by any preconceived definitions of academic disciplines. We have first of all found that the number of publications pertaining to digital ethics is exponentially increasing. We furthermore established that whereas one may expect digital ethics to be a species of ethics, we in fact found that the various questions pertaining to digital ethics are predominantly being discussed in computer science, law and biomedical science. It is in these fields, more than in the independent field of ethics, that ethical discourse is being developed around concrete and often technical issues. Moreover, it appears that some important ethical values are very prominent in one field (e.g., autonomy in medical science), while being almost absent in others. We conclude that to get a thorough understanding of, and grip on, all the hard ethical questions of a digital society, ethicists, policy makers and legal scholars will need to familiarize themselves with the concrete and practical work that is being done across a range of different scientific fields to deal with these questions.

This book discusses the relationship between the philosophy of science and philosophy of engineering, and demonstrates how philosophers of engineering design as well as design researchers can benefit from the conceptual toolkit that the philosophy of science has to offer. In this regard, it employs conceptual tools from the philosophical literature on scientific explanation to address key issues in engineering design and philosophy of engineering design. Specifically, the book focuses on assessing the explanatory value of function ascriptions used in engineering (...) design and philosophy of technical functions; on elaborating the structure of explanation in engineering design; on assessing the role and value of design representations in engineering design and philosophy thereof; and on elaborating means for the testing of design methods. Presenting a novel and effective approach to tackling key issues in the field, philosophers of engineering and design alike will greatly benefit from this book. (shrink)

From the 1960s, African theologians sought to decolonise biblical scholarship, calling for a hermeneutical approach that pays attention to the African sociocultural context – inculturation. One of the undergirding principles of inculturation is that there are African sociocultural questions that the Bible can address through the appropriate interpretative methodology. Thus, this culminated in the application of inculturation on different levels. Similarly, an analysis of Akan aphorisms – the anthology of valuable data on Akan anthropology and communitarian egalitarianism – and the (...) Johannine theology of unity reveals that there are sociocultural maladies that require inculturation. Consequently, the study employed Ukpong’s inculturation hermeneutics to read the Johannine unity ideation because it facilitates the cross-pollination of ideas – the Johannine unity ideation to critique the Akan culture and the conceptualisation of unity in Akan proverbial lore to enrich the understanding of the Johannine theology of unity. The findings indicated that Akan unity ideation receives its impetus from personal and communal benefits, making sustainability impossible without them. Additionally, it contravenes the tenets of Akan communalism and anthropology. Furthermore, it revealed that Christian unity is grounded on replicating the divine community; therefore, it can fill the lacunae in the Akan concept. Finally, it established that the culture enriches the text.Contribution: Given that this article is an interactive engagement between the Johannine and Akan concepts of unity, it contributes to the ongoing discussions on contextual theology – the inculturation of the New Testament in the African context. Furthermore, it contributes to the discussions on Akan communalism. (shrink)

Ethnicity reasoning offers one way of looking at social identity in the letter to the Hebrews. The context of socio-economic abuse and hardships of the audience creates a situation in which ethnicity in social identity becomes an important issue for the author of Hebrews to address. This article is a social-scientific study which explores how the author establishes the ethnic identity of the audience as people of God. While this ethnic identity indicates the more privileged position the readers occupy in (...) relation to the benefits of God accessible to them, it also provides the author with the appropriate social institutions and scripts by which his demand for appropriate response to God and the Christian group becomes appreciable and compelling. The article involves the definition of social-scientific criticism, ethnicity and social identity, and discusses the social context of the letter to the Hebrews. It then explains how some social scripts within specific ethnic institutions give meaning to the demands the author makes from his readers. (shrink)

In this paper I apply the mechanistic account of explanation to engineering science. I discuss two ways in which this extension offers further development of the mechanistic view. First, functional individuation of mechanisms in engineering science proceeds by means of two distinct sub types of role function, behavior function and effect function, rather than role function simpliciter. Second, it offers refined assessment of the explanatory power of mechanistic explanations. It is argued that in the context of malfunction explanations of technical (...) systems, two key desiderata for mechanistic explanations, ‘completeness and specificity’ and ‘abstraction’, pull in opposite directions. I elaborate a novel explanatory desideratum to accommodate this explanatory context, dubbed ‘local specificity and global abstraction’, and further argue that it also holds for mechanistic explanations of malfunctions in the biological domain. The overall result is empirically-informed understanding of mechanistic explanation in engineering science, thus contributing to the ongoing project of understanding mechanistic explanation in novel or relatively unexplored domains. I illustrate these claims in terms of reverse engineering and malfunction explanations in engineering science. (shrink)

This article interprets the logos Christology in the fourth gospel within Ewe-Ghanaian cosmic setting. The article employs a combination of the exegetical and mother tongue biblical hermeneutics as its methodologies. The article compares the concept of the logos in John 1:1–5, 14 with a similar concept in Ewe cosmology with the aim of finding their points of convergence and divergence. The article also identifies linguistic and theological gaps in the Ewe rendition of John 1:1–5, 14 and proposes a new translation (...) that addresses it. A translation of the logos in Ewe cosmic perspective renders the term nyagbe, the intelligible word which dwells with the female pair of Sogbe-Lisa and manifests itself from the absolute state of existence [ logo ] to the embodied state [ logosu ]. When nyagbe journeyed from the eternal state of existence to the embodied state of existence, it manifests itself at five different levels of existence until it reaches the final state where humans exist. Although believed to be the epitome of all creation, human beings are at the same time described as being at the shore of ignorance and therefore must continually climb the ladder of knowledge in order to free themselves from it. It is for this reason that humans constantly petition the cosmic forces for their salvation. The article therefore, identifies a soteriological gap created in the Ewe soteriology and concludes that the only soteriological response to the Ewe cosmic cry for deliverance from the state of ignorance is the logos incarnate in John 1:14. Contribution: The article contributes to the academic knowledge on the logos Christology in the prologue of the fourth gospel (John 1:1–5, 14), specifically in the use of mother tongue in biblical hermeneutics in Africa.

Globalisation develops at a staggering pace that envelopes and infiltrates local South African communities in various ways. Through technology a person can have access to anything today. Should the church try to keep up, or compete with such a reality?

Through re-evaluating the church’s missional intent, by (...) shifting the paradigm away from self-centred outcomes, the church should contribute to such a community’s articulation of faith.

The Akan people of Ghana have concepts of ethnicity and social identity which are similar to those found in the Mediterranean world, which find expression in the issues addressed in the letter to the Hebrews. This similarity makes the reading of Hebrews in light of Akan ethnicity and social identity possible, giving one the expected meaning from the perspective of those concepts as within the original context of the audience. This article therefore discusses some theories on ethnicity and social identity (...) as well as the Akan people of Ghana and their concepts of ethnicity and social identity. It further explains the social context of the letter of Hebrews against which Hebrews is then read in light of Akan ethnicity and social identity. The focus of this reading is on how the ethnic identity of the readers presented in Hebrews enhances the social identity of the readers and provides the means by which the author’s appeal to his readers for their faithfulness to God becomes meaningful and urgent.

This paper adds to the philosophical literature on mechanistic explanation by elaborating two related explanatory functions of idealisation in mechanistic models. The first function involves explaining the presence of structural/organizational features of mechanisms by reference to their role as difference-makers for performance requirements. The second involves tracking counterfactual dependency relations between features of mechanisms and features of mechanistic explanandum phenomena. To make these functions salient, we relate our discussion to an exemplar from systems biological research on the mechanism for countering (...) heat shock—the heat shock response system—in Escherichia coli bacteria. This research also reinforces a more general lesson: ontic constraint accounts in the literature on mechanistic explanation provide insufficiently informative normative appraisals of mechanistic models. We close by outlining an alternative view on the explanatory norms governing mechanistic representation. (shrink)

This article aims to present a realistic reading of the parable of the Lost Coin in Q. A realistic reading of the parable focuses on the social realia invoked by the parables, that is, the social realities and practices embedded by any given parable. As will be indicated, available documented papyri can be used to identify the possible social realia invoked by the parables, and this can help the modern reader to identify what is ‘normal’ or ‘abnormal’ in a parable (...) being interpreted. This, in turn, can help the modern reader to come to grips with the probable intended meaning of the parable. In a realistic reading of the Lost Coin, it is argued that two things are important: the price and daily consumption of oil, and the Lost Coin being one of the gendered doublets in Q. Apart from proposing a possible meaning of the Lost Coin, it is also indicated that a realistic reading explains why the seeking of the woman is described as being ἐπιμελῶς [diligent]. (shrink)

In the recent literature on explanation in biology, increasing attention is being paid to the connection between design explanation and mechanistic explanation, viz. the role of design principles and heuristics for mechanism discovery and mechanistic explanation. In this paper we extend the connection between design explanation and mechanism discovery by prizing apart two different types of design explanation and by elaborating novel heuristics that one specific type offers for mechanism discovery across species. We illustrate our claims in terms of two (...) lines of biological research on the biological advantages of organismal traits, one on the eye-size of giant squid, the other on foraging habits of specific bat species. We argue that this research illustrates useful heuristics for mechanism discovery across species, viz. reasoning strategies to infer likely mechanisms for a certain biological role based on assessments of the environmental conditions in which the role is performed efficiently and less or in-efficiently. We bring out the novel features of our analysis in terms of a comparison with mechanistic approaches to mechanism discovery, amongst which graph-theoretical ones, and by comparing the different types of design explanation and the discovery heuristics they support.

The parables of Jesus: Allegories or symbols of social transformation? This article reflects on a possible methodology that can be used to interpret the parables of Jesus preserved in the Synoptics (and the Gospel of Thomas). It is argued that the available versions of the parables of Jesus have already been allegorised, and that this should be taken into consideration when the extant versions of parables are interpreted as parables of the historical Jesus. The parables should also, as far as (...) possible, be interpreted against the social realia evoked by the parables. In this endeavour, Roman-Egypt inscriptions and papyri are in most cases the only sources available. The article concludes with a few examples, illustrating the possibilities of interpretation when the proposed methodology is applied. (shrink)

In engineering design research different models of functional decomposition are advanced side-by-side. In this paper I explain and validate this co-existence of models in terms of the Kuhnian thesis of methodological incommensurability. I advance this analysis in terms of the thesis’ construal of (non-algorithmic) theory choice in terms of values, expanding this notion to the engineering domain. I further argue that the (by some) implicated threat of the thesis to rational theory choice has no force in the functional decomposition case: (...) co-existence of different models of functional decomposition is rational from an instrumental point of view. My explanation covers cases in which different models are advanced as means for the same objective. Such cases cannot be explicated with the explanatory construct of variety in objectives, as advanced in other analyses of co-existing conceptualizations in engineering. (shrink)

In this paper we assess the explanatory role of idealizations in ‘design explanations’, a type of functional explanation used in biology. In design explanations, idealizations highlight which factors make a difference to phenomena to be explained: hypothetical, idealized, organisms are invoked to make salient which traits of extant organisms make a difference to organismal fitness. This result negates the view that idealizations serve only pragmatic benefits, and complements the view that idealizations highlight factors that do not make a difference. This (...) analysis in particular strengthens the perspective that idealizations are means to highlight difference making factors, and identifies a novel, more direct role for idealizations in doing so. It thus offers a novel argument why in some explanatory contexts idealizations are in-eliminable. (shrink)

Both the Johannine and Akan cultures are described in scholarly literature as collectivistic communities that value love as a communal value. Nonetheless, a scholarly analysis of the Akan concept reveals that Akan proverbial tradition promotes love motivated by the expectation of reciprocation. Thus, the article aimed to provide a biblical response to these challenges for Akan Christians, who hold love as both a traditional and theological value. Consequently, the study employed Gatti’s dialogic hermeneutics because it encourages engagement between text and (...) culture, viewing them as dialogue partners from which a call to action emanates directed at the interpreter’s context. Even though the Akan concept relates love to sacrifice, forgiveness and reciprocity, it promotes conditional love, thereby diminishing its concept of love-motivated sacrifices and reciprocity. By incarnating the concept of love that Jesus promotes and embodies in John, Akan Christians can establish a culture that reflects the community of God, proscribing conditional love and prescribing utmost and greater love – godly selfless and reciprocal love. In addition, it makes love the substratum of functional unity and interpersonal relationships. Ultimately, it makes love a divine command for the community of believers. Contribution: This article engages the Johannine and the Akan ideations of love through dialogic hermeneutics and, as such, contributes to African biblical hermeneutics and the ongoing discussions on the inculturation of the New Testament within the African context.
