In the theory of judgment aggregation, it is known for which agendas of propositions it is possible to aggregate individual judgments into collective ones in accordance with the Arrow-inspired requirements of universal domain, collective rationality, unanimity preservation, non-dictatorship and propositionwise independence. But it is only partially known (e.g., only in the monotonic case) for which agendas it is possible to respect additional requirements, notably non-oligarchy, anonymity, no individual veto power, or implication preservation. We fully characterize the agendas for which there (...) are such possibilities, thereby answering the most salient open questions about propositionwise judgment aggregation. Our results build on earlier results by Nehring and Puppe (2002), Nehring (2006), Dietrich and List (2007a) and Dokow and Holzman (2010a). (shrink)

Suppose several individuals (e.g., experts on a panel) each assign probabilities to some events. How can these individual probability assignments be aggregated into a single collective probability assignment? This article reviews several proposed solutions to this problem. We focus on three salient proposals: linear pooling (the weighted or unweighted linear averaging of probabilities), geometric pooling (the weighted or unweighted geometric averaging of probabilities), and multiplicative pooling (where probabilities are multiplied rather than averaged). We present axiomatic characterisations of each class of (...) pooling functions (most of them classic, but one new) and argue that linear pooling can be justified procedurally, but not epistemically, while the other two pooling methods can be justified epistemically. The choice between them, in turn, depends on whether the individuals' probability assignments are based on shared information or on private information. We conclude by mentioning a number of other pooling methods. (shrink)

The new field of judgment aggregation aims to merge many individual sets of judgments on logically interconnected propositions into a single collective set of judgments on these propositions. Judgment aggregation has commonly been studied using classical propositional logic, with a limited expressive power and a problematic representation of conditional statements ("if P then Q") as material conditionals. In this methodological paper, I present a simple unified model of judgment aggregation in general logics. I show how many realistic decision problems can (...) be represented in it. This includes decision problems expressed in languages of classical propositional logic, predicate logic (e.g. preference aggregation problems), modal or conditional logics, and some multi-valued or fuzzy logics. I provide a list of simple tools for working with general logics, and I prove impossibility results that generalise earlier theorems. (shrink)

The secession of prosperous regions may negatively affect the redistributive scheme of an established state. As a consequence, the capacity of its welfare system to support the inhabitants of poorer regions may be significantly reduced. Some authors assert that affluent groups who opt for full political independence violate duties of solidarity. This objection to the secession of prosperous regions can be based on different views of distributive justice. Here, following a distinction that has been introduced by Allen Buchanan, ‘subject centred’ (...) and ‘justice as reciprocity’ theories are explored. It is argued that both theories fail to support the case against the secession of wealthy groups. ‘Subject centred’ theories cannot explain special duties toward compatriots, whereas ‘justice as reciprocity’ theories cannot justify restrictions on exit rights. However, this does not mean that separatists have no moral duties vis-à-vis their fellow citizens. They are obliged to dissolve the political union in a fair way, e.g., by accepting responsibility for some share of the public debts. (shrink)

The article addresses the issue of rationing health care services, a topic currently being hotly debated in many countries. The author argues that the aspect of causal responsibility ought to play a decisive role in the allocation of limited medical resources. Starting out from Ronald Dworkin's distinction between option luck and brute luck, the appropriate and meaningful uses of the term causal responsibility are clarified first. A discussion of the conditions which might justify giving lower priority to patients whose illnesses (...) are the result of unhealthy behavior, like e.g. alcohol abuse, follows. Causal responsibility is then viewed in the context of private health insurance and the club model of organ donation. It is argued that individuals themselves are basically responsible for their decisions regarding insurance coverage and membership in organ donors' clubs. Causal responsibility is shown to be a more suitable criterion for rationing scarce medical resources than other criteria which might alternatively be considered, such as patients' age. (shrink)

In recent years theorists, such as Yael Tamir and David Miller, have proposed a liberal form of nationalism thereby combining two seemingly incompatible traditions of thought. Perhaps the most controversial element of their theories is the claim that national communities should be accorded with a right to political self-determination. In the article it is explained, firstly, why membership in a nation is seen as important for the individual’s well-being and, secondly, why statehood is deemed necessary for the thriving of the (...) nation. Subsequently, two problems of the liberal nationalists’ argument for political self-determination are discussed. It is argued, firstly, that national communities only need some form of regional autonomy to achieve their most important goals and, secondly, that non-national communities, e.g. religious groups, can base their demand for political sovereignity on the very same argument.

In a single framework, I address the question of the informational basis for evaluating social states. I particularly focus on information about individual welfare, individual preferences and individual (moral) judgments, but the model is also open to any other informational input deemed relevant, e.g. sources of welfare and motivations behind preferences. In addition to proving some possibility and impossibility results, I discuss objections against using information about only one aspect (e.g. using only preference information). These objections suggest a multi-aspect informational (...) basis for aggregation. However, the multi-aspect approach faces an impossibility result created by a lack of inter-aspect comparability. The impossibility could be overcome by measuring information on non-cardinal scales. (shrink)

Advancements in biological ageing research have shown that age-related diseases may be fought more effectively in the future by directly intervening into the ageing process. This prospect is associated with hopes for solving problems of demographic change. It also addresses raising awareness for complex ethical, legal and social issues that have hardly been a topic of discussion to date. Therefore, as the objective of our project, an interdisciplinary discourse module entitled “Ethics of Biogerontology” was developed to initiate a social debate (...) on the ethical, legal, and societal implications of biogerontology. The discourse module focuses on competences and argumentation skills and was developed with experts from relevant disciplines, e.g. biogerontology, social gerontology, philosophy, geriatrics, and medical ethics. Concepts of age and ageing are tightly interlinked with biogerontology and are as such relevant as teaching contents of the discourse module. The course module was tested in eight discourse teaching projects in research, medicine, and education in various partner institutions and evaluated based on an ethical competence model. This article describes the conception, including the learning objectives, of such a teaching course and the associated teaching contents. It also gives a justification for their selection. Finally, we summarize the results of the evaluation. (shrink)

Paul L. Lehmann was one of the leading Protestant theologians and ethicists of his generation. Working directly from archival sources and early writings, this article offers an account of the formation of key features of his distinctive theological perspective up to and including the first decades of his professional career. It argues that Lehmann prosecutes a distinctive and markedly Protestant form of public theology, centred on an understanding of the Word of God as a present, dynamic and humanising power, to (...) which Christian faith, life and thought give witness and serve catalytically. In this, Lehmann shows himself to be a premier advocate for lines of thinking he first encountered in the work of Karl Barth and of his friend, Dietrich Bonhoeffer. (shrink)

The claims of Mt. 5:17—20 are often taken to provide the interpretive key to the ethical claims of the Sermon on the Mount as a whole. The theological issue at stake here is the determinative relation between Christ's person and work and his teaching. This article explores the vital role played by the identity of Christ as the `fulfiller of the law' and `bringer of the Kingdom' in the exegesis of the Sermon offered by Eduard Thurneysen and Dietrich Bonhoeffer in (...) their respective works Die Bergpredigt (1936) and Nachfolge (1937). Both readings assert that the force and nature of the claims of the Sermon cannot be understood aright apart from constant attention to the difference made by the fact that Christ is the preacher. Out of this shared conviction, both theologians advance a reading of the Sermon as `the gospel itself' in the light of the eschatological identity of Jesus. Such readings of the Sermon, arising amidst the German Kirchenkampf of the 1930s, represent substantial contributions to the `responsible interpretation' of the Barmen Declaration (1934) whose second article states that, `As Jesus Christ is God's assurance of the forgiveness of all our sins, so in the same way and with the same seriousness is he also God's mighty claim upon our whole life.'.

The central question of this conference is whether the media can contribute to high quality social dialogue. The prospects for resolving that question positively in the “sound and fury” depend on recovering the idea of truth. At present the news media are lurching along from one crisis to another with an empty centre. We need to articulate a believable concept of truth as communication's master principle. As the norm of healing is to medicine, justice to politics, critical thinking to education, (...) craftsmanship to engineering, and stewardship to business, so truth-telling is the news profession's occupational norm. Truth-telling is the ethical framework that fundamentally reorders the media's professional culture and enables them to enrich social dialogue rather than undermine it.Historically the mainstream press has defined itself in terms of an objectivist worldview. Centred on human rationality and armed with the scientific method, the facts in news have been said to mirror reality. The aim has been true and incontrovertible accounts of a domain separate from human consciousness. In Bertrand Russell's formula, “truth consists in some form of correspondence between belief and fact” . In the received view, truth is defined in elementary epistemological terms as accurate representation. News corresponds to context-free neutral algorithms, and ethics is equated with impartiality.The attacks on this misguided view of human knowledge had already originated in Giambattista Vico's fantasia and Wilhelm Dilthey's verstehen in the counter-Enlightenment of the 18th century. They have continued with hermeneutics, critical theory in the Frankfurt School, American pragmatism, Wittgenstein's linguistic philosophy, Gramsci, and in their own way, Lyotard's denial of master narratives and Derrida's sliding signifiers; until the anti-foundationalism of our own day indicates a crisis in correspondence views of truth. Institutional structures remain Enlightenment-driven, but in principle the tide has turned currently toward restricting objectivism to the territory of mathematics, physics, and the natural sciences. In reporting, objectivity has become increasingly controversial as the working press' professional standard, though it will remain entrenched in our ordinary practices of news production and dissemination until an alternative mission for the press is convincingly formulated.The demise of correspondence views of truth has created a predicament for the notion of truth altogether. However, instead of appealing to coherence versions or abandoning the concept, truth needs to be relocated in the moral sphere. Truth is a problem of axiology rather than epistemology. With the dominant scheme no longer tenable, truth should become the province of ethicists who can reconstruct it as the news media's contribution to social dialogue.When truth is articulated in terms of a moral framework, we can mold its richly textured meaning around the Hebrew emeth , the Greek aletheia . In Serbo-Croatian the true is justified as with plumbline in carpentry. In the powerful wheel imagery of the Buddhist tradition, truth is the immovable axle. The Truth and Reconciliation Commission in South Africa presumes that sufferings from apartheid can be healed through truthful testimony. In Ghandhi's “satyagrapha,” the power of truth through the human spirit eventually wins over force . Dietrich Bonhoeffer's Ethics contends correctly that a truthful account lays hold of the context, motives, and presuppositions involved .Telling the truth depends on the quality of discernment so that penultimates do not gain ultimacy. Truth means, in other words, to strike gold, to get at “the core, the essence, the nub, the heart of the matter” . For Henry David Thoreau – though addressing a different issue – when we are truthful, we attempt to “drive life into a corner and¼if it proves to be mean, why then to get the genuine meanness out of it and publish its meanness to the world; or if it were sublime, to know it by personal experience and be able to give a true account of the encounter” . For the former secretary general of the United Nations, Dag Hammarskjold, “the most dangerous of all moral dilemmas is when we are obliged to conceal truth in order to help the truth be victorious” . In the Talmud, the liar's punishment is that no one believes him.Augustine , professor of rhetoric at Milan and later Bishop of Hippo, illustrates a non-correspondence view of truth. His rhetorical theory is a major contribution to the philosophy of communication, contradicting the highly secular and linear view of the ancient Greeks. As with Aristotle, rhetoric entails reasoned judgement for Augustine; however, he “break[s] away from Graeco-Roman rhetoric, moving instead toward ¼rhetoric as aletheiac act” . Rhetoric for him is not knowledge-producing or opinion-producing but truth-producing . The Epistolae Doctrina Christiana scourges the value-neutral, technical language of “word merchants” without wisdom.Truth is not fundamentally a prescriptive statement. The aletheiac act in Augustine “tends to be more relational than propositional, a dialogically interpersonal, sacramentally charitable act rather than a statement¼taking into account and being motivated by [the cardinal virtues] faith, hope, and charity” . The truth for him does not merely make things clear, but motivates us to belief and action. In truthful communication for Augustine, “it is not enough to seek to move men's minds, merely for the sake of power; instead, the power to move is to be used to lead men to truth”. (shrink)

It is sometimes alleged that the study of emotion and the study of value are currently pursued as relatively autonomous disciplines. As Kevin Mulligan notes, “the philosophy and psychology of emotions pays little attention to the philosophy of value and the latter pays only a little more attention to the former.” (2010b, 475). Arguably, the last decade has seen more of a rapprochement between these two domains than used to be the norm (cf. e.g. Roeser & Todd 2014). But there (...) still seems to be considerable potential for exchange and dialogue if the situation is compared with their intimate relationship in central strands of early realist phenomenology. The philosopher perhaps most representative of this ecumenical approach is Husserl’s early student Dietrich von Hildebrand (1889-1977). From the very early stages of his philosophical career, Hildebrand has developed one of the most original, comprehensive and nuanced accounts of emotions at whose core is a detailed examination of their connection to value. While his central concern with the ethical significance of our affective life is in many ways continuous with Scheler’s work and draws crucially on Reinach’s philosophy of mind, Hildebrand’s own reflections considerably expand on and substantially modify the picture of the ontology and normative role of emotions defended by these authors. In this article, I reconstruct Hildebrand’s view of emotions with a particular focus on those aspects which represent his most distinctive contribution to this subject. (shrink)

Agents are often assumed to have degrees of belief (“credences”) and also binary beliefs (“beliefs simpliciter”). How are these related to each other? A much-discussed answer asserts that it is rational to believe a proposition if and only if one has a high enough degree of belief in it. But this answer runs into the “lottery paradox”: the set of believed propositions may violate the key rationality conditions of consistency and deductive closure. In earlier work, we showed that this problem (...) generalizes: there exists no local function from degrees of belief to binary beliefs that satisfies some minimal conditions of rationality and non-triviality. “Locality” means that the binary belief in each proposition depends only on the degree of belief in that proposition, not on the degrees of belief in others. One might think that the impossibility can be avoided by dropping the assumption that binary beliefs are a function of degrees of belief. We prove that, even if we drop the “functionality” restriction, there still exists no local relation between degrees of belief and binary beliefs that satisfies some minimal conditions. Thus functionality is not the source of the impossibility; its source is the condition of locality. If there is any non-trivial relation between degrees of belief and binary beliefs at all, it must be a “holistic” one. We explore several concrete forms this “holistic” relation could take. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Constituer le Réel. Noétique et Métaphysique chez Dietrich de Freiberg by Véronique DecaixBrian Francis ConollyVéronique Decaix. Constituer le Réel. Noétique et Métaphysique chez Dietrich de Freiberg. Paris: Librairie Philosophique J. Vrin, 2021. Pp. 336. Paperback, $48.00.Dietrich of Freiberg's theory of the constitutive power of the intellect, as presented in his De origine rerum praedicamentalium, has proved unusually resistant to contextualization within the philosophical and theological discussions at the (...) University of Paris in the last two decades of the thirteenth century. There is little indication in the quodlibet literature that any of his contemporaries were aware of his unusual doctrine, let alone interested in responding to it, and Dietrich himself provides few hints as to which quaestiones of contemporary interest he is responding to. One therefore welcomes this study by Véronique Decaix in which it is argued that "il est irréfutable que les concepts centraux du De origine ont été forgés dans une discussion permanente avec Henri de Gand" (223). Drawing upon and developing the work of Pasquale Porro, Jan Aersten, and others, Decaix establishes Dietrich's indebtedness to Henry of Ghent, all while providing a comprehensive and remarkably clear, detailed, and precise presentation of Dietrich's theory of the constitutive power of the intellect. [End Page 706]Particularly noteworthy is the manner in which Decaix clarifies that there are several distinct ways in which the intellect, on Dietrich's theory, exercises its constitutive power. Thus, for instance, "categorial constitution," whereby certain relations and the six posterior relative categories are constituted, is distinguished from "quidditative constitution," wherein a real natural thing is constituted in its quidditative being, which is at the same time the mode or manner in which the intellect constitutes its own proper object. Decaix clarifies that such modes of constitution differ not only with respect to what is constituted, but by the kind of causality exercised by the intellect. Categorial constitution is a kind of formal causality—because it concerns only accidents, and because intellect grasps these accidents "sur une modalité déduite d'un élément extrinsèque" (284)—whereas quidditative constitution is efficient—it is "plus fondamentale, car elle est plus essentielle et plus intérieure" and "s'exerce sur la forme substantielle et cause l'étant en tant qu'étant" (286). In either case, whether the mode of constitution is categorial or quidditative, Decaix makes clear that constitution is not creation, and does not pertain to the reality or absolute entity of the thing affected by the intellect's constitutive power. Rather, constitution in the relevant sense here entails introducing and imposing upon the real natural thing a new mode of being: with respect to categorial constitution, that mode of being is ad aliud (to be in relation to another); with respect to quidditative constitution, the constituted mode of being is quidditative being.Decaix argues that Dietrich consciously develops his theory of categorial relation within the framework provided by Henry of Ghent. She cites as evidence, among other factors, that Dietrich concludes his analysis of categorial relation with what Decaix calls the "exacte contre-pied" (154) to question 3 of Henry's Quodlibet IX: "Utrum circumscripta re sui fundamenti relatio possit signari per nomen primae impositionis?" Dietrich in effect responds: "Si autem ab huiusmodi entibus removeamus actum rationis, tunc secundum nullum modum sunt entia quantum ad id, quod significatur per nomen, sed relinquitur sola realitas et entitas fundamenti" (160).Question 3 of Henry's Quodlibet IX is still more important for Decaix's argument. For she sees herein more than a germ of Dietrich's doctrine of the constitutive power of the intellect. As Decaix explains, in addition to the real foundation (quantity or quality) provided by nature, and the pure ratio of relation, provided by the intellect, Henry introduces the modus characterizatus a re, whereby the peculiar nature of the foundation (e.g. the length or the color) particularizes the general notion of the pure relation (157–58). Thus, the real, particular relation, for example, "is shorter than" or "is similar to," arises only from both nature and the intellect as joint contributing causes. In this... (shrink)

The Christian does not live in a vacuum, says the author, but in a world of government, politics, labor, and marriage. Hence, Christian ethics cannot exist in a vacuum what the Christian needs, claims Dietrich Bonhoeffer, is concrete instruction in a concrete situation. Although the author died before completing his work, this book is recognized as a major contribution to Christian ethics. The root and ground of Christian ethics, the author says, is the reality of God as revealed in Jesus (...) Christ. This reality is not manifest in the Church as distinct from the secular world such a juxtaposition of two separate spheres, Bonhoeffer insists, is a denial of God's having reconciled the whole world to himself in Christ. On the contrary, God's commandment is to be found and known in the Church, the family, labor, and government. His commandment permits man to live as man before God, in a world God made, with responsibility for the institutions of that world. (shrink)

The widely discussed "discursive dilemma" shows that majority voting in a group of individuals on logically connected propositions may produce irrational collective judgments. We generalize majority voting by considering quota rules, which accept each proposition if and only if the number of individuals accepting it exceeds a given threshold, where different thresholds may be used for different propositions. After characterizing quota rules, we prove necessary and sufficient conditions on the required thresholds for various collective rationality requirements. We also consider sequential (...) quota rules, which ensure collective rationality by adjudicating propositions sequentially and letting earlier judgments constrain later ones. Sequential rules may be path-dependent and strategically manipulable. We characterize path-independence and prove its essential equivalence to strategy-proofness. Our results shed light on the rationality of simple-, super-, and sub-majoritarian decision-making. (shrink)

Called by Karl Barth the brilliant Ethics of Dietrich Bonhoeffer, this book is finally being recognized as Bonhoeffers magnum opus and one of the most important works of Christian ethics of the last century.

Behaviourism is the view that preferences, beliefs, and other mental states in social-scientific theories are nothing but constructs re-describing people's behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. (...) We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states. (shrink)

All existing impossibility theorems on judgment aggregation require individual and collective judgment sets to be consistent and complete, arguably a demanding rationality requirement. They do not carry over to aggregation functions mapping profiles of consistent individual judgment sets to consistent collective ones. We prove that, whenever the agenda of propositions under consideration exhibits mild interconnections, any such aggregation function that is "neutral" between the acceptance and rejection of each proposition is dictatorial. We relate this theorem to the literature.

We introduce a “reason-based” framework for explaining and predicting individual choices. It captures the idea that a decision-maker focuses on some but not all properties of the options and chooses an option whose motivationally salient properties he/she most prefers. Reason-based explanations allow us to distinguish between two kinds of context-dependent choice: the motivationally salient properties may (i) vary across choice contexts, and (ii) include not only “intrinsic” properties of the options, but also “context-related” properties. Our framework can accommodate boundedly rational (...) and sophisticatedly rational choice. Since properties can be recombined in new ways, it also offers resources for predicting choices in unobserved contexts. (shrink)

This is the first complete, one-volume English translation of the ancient Chinese text Xunzi, one of the most extensive, sophisticated, and elegant works in the tradition of Confucian thought. Through essays, poetry, dialogues, and anecdotes, the Xunzi articulates a Confucian perspective on ethics, politics, warfare, language, psychology, human nature, ritual, and music, among other topics. Aimed at general readers and students of Chinese thought, Eric Hutton’s translation makes the full text of this important work more accessible in English than ever (...) before. Named for its purported author, the Xunzi has long been neglected compared to works such as the Analects of Confucius and the Mencius. Yet interest in the Xunzi has grown in recent decades, and the text presents a much more systematic vision of the Confucian ideal than the fragmented sayings of Confucius and Mencius. In one famous, explicit contrast to them, the Xunzi argues that human nature is bad. However, it also allows that people can become good through rituals and institutions established by earlier sages. Indeed, the main purpose of the Xunzi is to urge people to become as good as possible, both for their own sakes and for the sake of peace and order in the world. In this edition, key terms are consistently translated to aid understanding and line numbers are provided for easy reference. Other features include a concise introduction, a timeline of early Chinese history, a list of important names and terms, cross-references, brief explanatory notes, a bibliography, and an index.

Which rules for aggregating judgments on logically connected propositions are manipulable and which not? In this paper, we introduce a preference-free concept of non-manipulability and contrast it with a preference-theoretic concept of strategy-proofness. We characterize all non-manipulable and all strategy-proof judgment aggregation rules and prove an impossibility theorem similar to the Gibbard--Satterthwaite theorem. We also discuss weaker forms of non-manipulability and strategy-proofness. Comparing two frequently discussed aggregation rules, we show that “conclusion-based voting” is less vulnerable to manipulation than “premise-based voting”, (...) which is strategy-proof only for “reason-oriented” individuals. Surprisingly, for “outcome-oriented” individuals, the two rules are strategically equivalent, generating identical judgments in equilibrium. Our results introduce game-theoretic considerations into judgment aggregation and have implications for debates on deliberative democracy. (shrink)

Recently, a number of philosophers of biology have endorsed views about random drift that, we will argue, rest on an implicit assumption that the meaning of concepts such as drift can be understood through an examination of the mathematical models in which drift appears. They also seem to implicitly assume that ontological questions about the causality of terms appearing in the models can be gleaned from the models alone. We will question these general assumptions by showing how the same equation (...) — the simple 2 = p2 + 2pq + q2 — can be given radically different interpretations, one of which is a physical, causal process and one of which is not. This shows that mathematical models on their own yield neither interpretations nor ontological conclusions. Instead, we argue that these issues can only be resolved by considering the phenomena that the models were originally designed to represent and the phenomena to which the models are currently applied. When one does take those factors into account, starting with the motivation for Sewall Wright’s and R.A. Fisher’s early drift models and ending with contemporary applications, a very different picture of the concept of drift emerges. On this view, drift is a term for a set of physical processes, namely, indiscriminate sampling processes. (shrink)

Musica Poetica provides an unprecedented examination of the development of Baroque musical thought. The initial chapters, which serve as an introduction to the concept and teachings of musical-rhetorical figures, explore Martin Luther's theology of music, the development of the Baroque concept of musica poetica, the idea of the affections in German Baroque music, and that music's use of the principles and devices of rhetoric. Dietrich Bartel then turns to more detailed considerations of the musical-rhetorical figures that were developed in Baroque (...) treatises and publications. After brief biographical sketches of the major theorists, Bartel examines those theorists' interpretation and classification of the figures. The book concludes with a detailed presentation of the musical-rhetorical figures, in which each theorist's definitions are presented in the original language and in parallel English translations. Bartel's clear, detailed analysis of German Baroque musical-rhetorical figures, combined with his careful translations of interpretations of those figures from a wide range of sources, make this book an indispensable introduction and resource for all students of Baroque music. Dietrich Bartel is an associate professor in the Department of Music at Canadian Mennonite Bible College (affiliated with University of Manitoba). (shrink)

Comparative approaches to language evolution are essential but cannot by themselves resolve the timing and context of evolutionary events since the last common ancestor with chimpanzees. Archaeology can help to fill this gap, but only if properly integrated with evolutionary theory and the ethnographic, ethological, and experimental analogies required to reconstruct the broader social, behavioral, and neurocognitive implications of ancient artifacts. The current contribution elaborates a technological pedagogy hypothesis of language origins by developing the concept of an evolving human technological (...) niche and applying it to investigate two key transitions posited by Arbib’s Mirror System Hypothesis: from complex action recognition and imitation to proto-language, and from proto-language to language.
