Any account of “what is special about the human brain” (Passingham 2008) must specify the neural basis of our unique ability to produce speech and delineate how these remarkable motor capabilities could have emerged in our hominin ancestors. Clinical data suggest that the basal ganglia provide a platform for the integration of primate-general mechanisms of acoustic communication with the faculty of articulate speech in humans. Furthermore, neurobiological and paleoanthropological data point at a two-stage model of the phylogenetic evolution of this (...) crucial prerequisite of spoken language: (i) monosynaptic refinement of the projections of motor cortex to the brainstem nuclei that steer laryngeal muscles, presumably, as part of a “phylogenetic trend” associated with increasing brain size during hominin evolution; (ii) subsequent vocal-laryngeal elaboration of cortico-basal ganglia circuitries, driven by human-specificFOXP2mutations.;>This concept implies vocal continuity of spoken language evolution at the motor level, elucidating the deep entrenchment of articulate speech into a “nonverbal matrix” (Ingold 1994), which is not accounted for by gestural-origin theories. Moreover, it provides a solution to the question for the adaptive value of the “first word” (Bickerton 2009) since even the earliest and most simple verbal utterances must have increased the versatility of vocal displays afforded by the preceding elaboration of monosynaptic corticobulbar tracts, giving rise to enhanced social cooperation and prestige. At the ontogenetic level, the proposed model assumes age-dependent interactions between the basal ganglia and their cortical targets, similar to vocal learning in some songbirds. In this view, the emergence of articulate speech builds on the “renaissance” of an ancient organizational principle and, hence, may represent an example of “evolutionary tinkering” (Jacob 1977).

Scholars have long been captivated by the parallels between birdsong and human speech and language. In this book, leading scholars draw on the latest research to explore what birdsong can tell us about the biology of human speech and language and the consequences for evolutionary biology. They examine the cognitive and neural similarities between birdsong learning and speech and language acquisition, considering vocal imitation, auditory learning, an early vocalization phase, the structural properties of birdsong and human language, and the striking (...) similarities between the neural organization of learning and vocal production in birdsong and human speech. After outlining the basic issues involved in the study of both language and evolution, the contributors compare birdsong and language in terms of acquisition, recursion, and core structural properties, and then examine the neurobiology of song and speech, genomic factors, and the emergence and evolution of language.

This book introduces generative grammar as an area of study and asks what it tells us about the human mind. Wolfram Hinzen lays the foundation for the unification of modern generative linguistics with the philosophies of mind and language. He introduces Chomsky's program of a 'minimalist' syntax as a novel explanatory vision of the human mind. He explains how the Minimalist Program originated in work in cognitive science, biology, linguistics, and philosophy, and examines its implications for work in these (...) fields. He considers the way the human mind is designed when seen as an arrangement of structural patterns in nature, and argues that its design is the product not so much of adaptive evolutionary history as of principles and processes that are ahistorical and internalist in character. Linguistic meaning, he suggests, arises in the mind as a consequence of structures emerging on formal rather than functional grounds. From this he substantiates an unexpected and deeply unfashionable notion of human nature. Clearly written in nontechnical language and assuming a limited knowledge of the fields it examines and links, Minimal Mind Design will appeal to a wide range of scholars in linguistics, philosophy, and cognitive science. It also provides an exceptionally clear insight into the nature and aims of Chomsky's Minimalist Program. (shrink)

What are the semantic representations that underlie language production? We use structural priming to distinguish between two competing theories. Thematic roles define semantic structure in terms of atomic units that specify event participants and are ordered with respect to each other through a hierarchy of roles. Event structures instead instantiate semantic structure as embedded sub‐predicates that impose an order on verbal arguments based on their relative positioning in these embeddings. Across two experiments, we found that priming for datives depended on (...) the degree of overlap in event structures. Specifically, while all dative structures showed priming, due to common syntax, there was a boost for compositional datives priming other compositional datives. Here, the two syntactic forms have distinct event structures. In contrast, there was no boost in priming for dative light verbs, where the two forms map onto a single event representation. On the thematic roles hypothesis, we would have expected a similar degree of priming for the two cases. Thus, our results support event structural approaches to semantic representation and not thematic roles. (shrink)

Life's Solution builds a persuasive case for the predictability of evolutionary outcomes. The case rests on a remarkable compilation of examples of convergent evolution, in which two or more lineages have independently evolved similar structures and functions. The examples range from the aerodynamics of hovering moths and hummingbirds to the use of silk by spiders and some insects to capture prey. Going against the grain of Darwinian orthodoxy, this book is a must read for anyone grappling with the meaning of (...) evolution and our place in the Universe. Simon Conway Morris is the Ad Hominen Professor in the Earth Science Department at the University of Cambridge and a Fellow of St. John's College and the Royal Society. His research focuses on the study of constraints on evolution, and the historical processes that lead to the emergence of complexity, especially with respect to the construction of the major animal body parts in the Cambrian explosion.

This interdisciplinary book considers the relationship between language and thought from a philosophical perspective, drawing both on the philosophical study of language and the purely formal study of grammar, and arguing that the two should align. The claim is that grammar provides homo sapiens with the ability to think in certain grammatical ways and that this in turn explains the vast cognitive powers of human beings. Evidence is considered from biology, the evolution of language, language disorders, and linguistic phenomena.

Philosophie ist wissentlicher Einhegungsversuch des Nichtwissens. Wo immer sie daher die Bedeutung und Wirksamkeit des Nichtwissens nicht präsent hält, verfehlt sie ihre Mitte. Das hat sich seit der Antike bis heute nicht geändert. Allerdings blieb es den Interessen der Zeiten und Denker vorbehalten, die Mischformen von Wissen und Nichtwissen in ihrer Eigenart mehr oder weniger eingehend zu analysieren. Selbst wenn die sokratische Formel vom Wissen des Nichtwissens durchgängig gerne zitiert wurde: Wie die Formen des Wissens in ihren schwachen, aber unentbehrlichen (...) Variationen näherhin zu charakterisieren sind, hat über die Zeiten die Philosophen eher selten interessiert. Aber diese schwachen Formen des Wissens wie Ahnung, Mutmaßung und das Gefühl als Grundlage von Situationseinschätzungen sind für unseren Alltag von erheblicher Bedeutung. Wolfram Hogrebe diskutiert in seinem Buch Formen des Wissens in ihrer szenischen Relevanz, ja das Szenische als Wissensform selbst. Ein von der Philosophie bislang völlig ignoriertes Thema. Aber die Philosophie kann gar nicht ignorieren, ohne dennoch auch in ihrem Absehen noch etwas Mitgesehenes hervortreten zu lassen. (shrink)

Solidarity is one of the central concepts in social theory and has gained much attention due to the multiple challenges that the EU has been facing the last decade and due to the most recent COVID-19 pandemic. Although the debate on the nature and conditions of solidarity has been revitalized, there remains a large variety in how to conceptualize solidarity. In contrast to other approaches, we do not conceive solidarity as normative concept, but as descriptive–analytical one. Therefore, we provide a (...) theory-based definition that is prone to capture the empirical dimensions of solidarity. Accounting for the dynamic and interactive character of solidarity as subject to permanent societal and political renegotiation, we conceptualize solidarity from a discourse perspective and follow a multilevel design breaking down the understandings of solidarity on different levels. This approach contributes to the research of solidarity that is interested to capturing the ‘real world’ dimensions of solidarity. (shrink)

The important yet contradictory role of innovation in society calls for a philosophy of innovation. Critically exploring innovation in relation to values, the economy and social change, Rafael Ziegler proposes a collaborative theory and practice of innovation that aims to liberate possibilities for our common futures. Following cues from the arts and drawing on the innovation literature across the social sciences, this book exposes pro-innovation bias and the gospel of disruptive change. Not only entrepreneurs but also civic networks and (...) tinkerers are discussed as sources of innovation, and social change as a balancing act of innovation, exnovation and restoration. The discussion of capabilitarian, communitarian, liberal, republican and socialist ideas of justice and innovation leads Ziegler to a transformative proposal: 'enough innovation' based on enough for all and with respect for all. This is a thought-provoking read for scholars working on sustainability-transformation, democratic, responsible and social innovation, and philosophy of economics. (shrink)

This pioneering book lays new foundations for the study of reference and truth.

The view that proper names are uniformly predicates has recently gained prominence. I review linguistic evidence against it. Overall, the linguistic evidence suggests that proper names function as predicates when they appear in a grammatically predicative position and as referential expressions when they are grammatically in a referential position. Conceptual grounds on which the predicativist view might nonetheless be upheld include ‘uniformity’, i.e., that a single semantic value be lexically specified for names in all of their occurrences irrespective of differences (...) in their grammar. However, ‘being a predicate’ or ‘being referential’ are not lexical properties of words but indications for how these grammatically function on an occasion of their use. Moreover, the intuitively referential and intuitively predicative uses of proper names precisely covary with grammatical differences. A proper name is therefore a predicate when it is predicatively used, not when its grammar and meaning are different. Given this grammar-meaning alignment there is no motivation to posit a novel ‘covert syntax’ for names in their referential uses, which breaks this alignment. Cross-linguistic evidence from languages such as Catalan, which features overt determiners in referential uses of proper names, moreover turns out to strongly support the view that the grammar of human language is systematically sensitive to differences in the referential and predicative uses of names.

This chapter explores some fundamental consequences of the correspondence between physical process and computations. Most physical questions may be answerable only through irreducible amounts of computation. Those that concern idealized limits of infinite time, volume, or numerical precision can require arbitrarily long computations, and so be considered formally undecidable. The behavior of a physical system may always be calculated by simulating explicitly each step in its evolution. Much of theoretical physics has, however, been concerned with devising shorter methods of calculation (...) that reproduce the outcome without tracing each step. Computational irreducibility is common among the systems investigated in mathematics and computation theory, but it may well be the exception rather than the rule, since most physical questions may be answerable only through irreducible amounts of computation.

Wolfram Hogrebe beschäftigt sich in diesem Buch mit dem sogenannten Zwischenreich - einem alten philosophischen Gedanken, wonach das Philosophieren es mit einer Art von Zwischenraum zu tun hat, der die Ordnungen der Begriffe und der Vorstellungen in eine bemerkenswerte Schwebe bringt.

Thema bei so unterschiedlichen Philosophen und Dichtern wie Gottfried Wilhelm Leibniz, Gotthold Ephraim Lessing, Martin Heidegger, Henry David Thoreau und Peter Handke ist. (shrink)

Die Fragestellungen der Metaphysik, so scheint es, sind nicht mehr zeitgemäß. Der Begriff erinnert an abgehobene Systeme ohne jeden Realitätssinn. Dabei gibt es kein Denken ohne Metaphysik. Unter Bezugnahme auf die Traditionen der Phänomenologie und der französischen Philosophie versteht Robert Hugo Ziegler Endlichkeit als eine positive Auszeichnung, während der Begriff der Zeitlichkeit die erste Dimension von Sein beschreibt. Sein grundlegender Beitrag zur Reflexion über Mensch und Welt zeigt, wie sich die Philosophie selbstbewusst einer Erneuerung der Metaphysik stellen kann.

The experience of having to suffer debilitating pain is far too common in the United States, and many patients continue to be inadequately treated by their doctors. Although many physicians freely admit that their pain management practices may have been somewhat lacking, many more express concern that the prescribing of heightened levels of opioid analgesics may result in closer regulatory scrutiny, criminal investigation, or even criminal prosecution.Although several researchers have examined the regulatory environment and the threat of sanction or harm (...) it poses to physicians and patients, few have examined the likelihood of investigation or prosecution stemming from the aggressive use of opioids in physician-directed pain management. Accordingly, in an effort to assess whether the fear of prosecution is realistic and, if so, what factors contribute to its likelihood, we surveyed chief prosecutors in four states about their knowledge, opinions, and attitudes concerning opioids and the prosecution of physicians stemming from the treatment of patients who were either terminally ill or suffering from chronic noncancer pain.

In this volume, a diverse group of world experts in personality assessment showcase a range of different viewpoints on response distortion. Contributors consider what it means to "fake" a personality assessment, why and how people try to obtain particular scores on personality tests, and what types of tests people can successfully manipulate. The authors present and discuss the usefulness of a range of traditional and cutting-edge methods for detecting and controlling the practice of faking. These methods include social desirability scales, (...) warnings, affective neutralization, unidimensional and multidimensional pairwise preferences, decision trees, linguistic analysis, situational measures, and methods based on item response theory. The wide range of viewpoints presented in this book are then summarized, synthesized, and evaluated. The authors make practical recommendations and suggest areas for future research. Anyone who wonders whether people exaggerate or lie outright on personality tests -- or questions what psychologists can and should do about it -- will find in this book stimulating questions and useful answers.

A traditional view maintains that thought, while expressed in language, is non-linguistic in nature and occurs in non-linguistic beings as well. I assess this view against current theories of the evolutionary design of human grammar. I argue that even if some forms of human thought are shared with non-human animals, a residue remains that characterizes a unique way in which human thought is organized as a system. I explore the hypothesis that the cause of this difference is a grammatical way (...) of structuring semantic information, and I present evidence that the organization of grammar precisely reflects the organization of a specific mode of thought apparently distinctive of humans. Since there appears to be no known non-grammatical structuring principle for the relevant mode of thought, I suggest that grammar is that principle, with no independent ?Language of Thought? needed.

In this volume, Rabbi Aharon Lichtenstein explores the development of the religious personality. He advocates a life centered on the service of God, but recognizes multiple paths to this goal. Acknowledging that both the Jewish value system and human experience are multifaceted, he examines the relevant issues from an unusually wide perspective. Rabbi Lichtenstein's essays reflect not only a staunch commitment to Halakha and a firm grounding in rigorous Torah study, but also a deep spirituality, a profound moral sensitivity, and (...) a keen awareness of both the challenges and opportunities of modernity. While being enlightened by Rabbi Lichtenstein's penetrating analyses and wide-ranging learning, the reader will also be inspired by the beauty of his vision of the religious life. These essays originated as lectures, and have been selected and adapted for print by Rabbi Reuven Ziegler. (shrink)

Reaktionäres Denken ist wieder in Mode. Aber was ist das eigentlich? Wodurch unterscheidet es sich von anderen Formen des Denkens? Und welche philosophischen Instrumente können gegen dessen erneutes Erstarken wirken? Robert Hugo Ziegler analysiert beispielhaft Autoren wie Jünger, Heidegger, Schmitt und Rand und schlägt einen systematischen Begriff des reaktionären Denkens vor. Damit entmystifiziert er eine Diskursform, die letztlich nur in der eigenen Mystifizierung besteht, und bezieht auch politisch Stellung gegen das Wiederaufleben der Reaktion.

Nous assistons aujourd'hui à un formidable mouvement de reféodalisation du monde. C'est que le 11 septembre n'a pas seulement été l'occasion pour George W. Bush d'étendre l'emprise des Etats-Unis sur le monde, l'événement a frappé les trois coups de la mise en coupe réglée des peuples de l'hémisphère Sud par les grandes sociétés transcontinentales. Pour parvenir à imposer ce régime inédit de soumission des peuples aux intérêts des grandes compagnies privées, il est deux armes de destruction massive dont les maîtres (...) de l'empire de la honte savent admirablement jouer : la dette et la faim. Par l'endettement, les Etats abdiquent leur souveraineté ; par la faim qui en découle, les peuples agonisent et renoncent à la liberté. Cette formidable machine à broyer et à soumettre ne supporte plus aucune des limitations que le droit international prétendait traditionnellement imposer aux rapport entre les États et entre les peuples. Du coup, c'est le régime de la violence structurelle et permanente qui, partout, gagne du terrain au Sud, tandis que le droit international agonise. Mais qui sont donc ces cosmocrates qui, peu à peu, privatisent jusqu'à l'eau que les peuples doivent désormais leur acheter? Ce livre traque leurs méthodes les plus sournoises : ici on brevète le vivant, là on casse les résistances syndicales, ailleurs on impose la culture des OGM par la force. Oui, c'est bien l'empire de la honte qui s'est mis subrepticement en place sur la planète. Mais c'est précisément sur la honte qu'est fondé le ressort révolutionnaire, comme nous l'ont appris les insurgés de 1789. Cette révolution, elle est en marche : insurrections des consciences ici, insurrections de la faim là-bas. Elle seule peut conduire à la refondation du droit à la recherche du bonheur, cette vieille affaire du XVIIIe siècle. Jean Ziegler, qui témoigne ici d'une connaissance exceptionnelle du terrain, y appelle sans réserve en conclusion. (shrink)

Wir sind Teil einer Natur, die uns übersteigt - Grund genug, die Natur wieder zum Gegenstand philosophischer Reflexionen zu machen.

Medicalized Death and the Right to Die Movement Prior to the 20th Century, most Americans died at home, surrounded by family, friends, and neighbors. Religion, not medicine, governed the death bed for there was little physicians could do for the dying. Eventually, however, advances in medicine and technology would lead to dramatic changes in the timing and location of death: patients not only began living longer, they were also dying longer, and unlike their predecessors, were more likely to die alone, (...) in institutions, and among strangers. Modern medicine, in its zeal to conquer death, had become obsessed with its curative function and ability to extend the lives of the dying. To many in the medical community, death represented failure and was something to be avoided at all costs, and like many other social problems in the United States, had become medicalized. (shrink)

Much philosophical attention has been devoted to the truth predicates of natural language and their logic. However, lexical truth predicates are neither necessary nor sufficient for a truth-attribution to occur, which warrants closer attention to the grammar of truth attribution. A unified analysis of five constructions is offered here, in two of which the lexical truth predicate occurs (It's true that John left and That John left is true), while in the three remaining, it does not (John left; It seems (...) that John left; and It's that John left). This analysis is philosophically significant for four reasons. First, it explains why speakers of natural language find standard instances of Tarski-inspired equivalences (e.g. That John left is true iff John left) intuitively compelling. Second, it derives the widespread ‘deflationist’ intuition that truth has no substantive content. Third, insofar as the deflationist sees insights on truth as flowing from understanding our practice of truth attribution, it furthers the deflationist agenda through a new analysis of such attributions. Finally, it advances the philosophical project of the ‘naturalization’ of truth by reducing our understanding of truth to our competence in the grammar of truth, as an aspect of our biological endowment.

For regular sets in Euclidean space, previous work has identified twelve ‘basic’ computability notions to which many previous notions considered in literature were shown to be equivalent. With respect to those basic notions we now investigate on the computability of natural operations on regular sets: union, intersection, complement, convex hull, image, and pre-image under suitable classes of functions. It turns out that only few of these notions are suitable in the sense of rendering all those operations uniformly computable.

A defining assumption in the debate on contextual influences on truth-conditional content is that such content is often incompletely determined by what is specified in linguistic form. The debate then turns on whether this is evidence for positing a more richly articulated logical form or else a pragmatic process of free enrichment that posits truly unarticulated constituents that are unspecified in linguistic form. Questioning this focus on semantics and pragmatics, this article focuses on the independent grammatical dimensions of the problem. (...) Against the background of a principled account of the different ways in which the lexicon and the grammar, respectively, determine aspects of propositional meaning, and an uncontentious notion of content, nothing turns out to be ‘missing’ in grammatical expressions in order for them to encode complete propositional thoughts. As this predicts, when putatively hidden constituents are made overt or are otherwise added, propositions result that are systematically different from the thoughts originally expressed. Context, while potentially affecting lexically specified aspects of meaning, never affects grammar-determined ones, suggesting a specific role for grammar in the normal cognitive mode. (shrink)

Apologies. The purpose of the following talk is to give an overview of the present state of aims, methods and results in Pure Proof Theory. Shortage of time forces me to concentrate on my very personal views. This entails that I will emphasize the work which I know best, i.e., work that has been done in the triangle Stanford, Munich and Münster. I am of course well aware that there are as important results coming from outside this triangle and I (...) apologize for not displaying these results as well.Moreover the audience should be aware that in some points I have to oversimplify matters. Those who complain about that are invited to consult the original papers.1.1. General. Proof theory startedwithHilbert's Programme which aimed at a finitistic consistency proof for mathematics.By Gödel's Theorems, however, we know that we can neither formalize all mathematics nor even prove the consistency of formalized fragments by finitistic means. Inspite of this fact I want to give some reasons why I consider proof theory in the style of Gentzen's work still as an important and exciting field of Mathematical Logic. I will not go into applications of Gentzen's cut-elimination technique to computer science problems—this may be considered as applied proof theory—but want to concentrate on metamathematical problems and results. In this sense I am talking about Pure Proof Theory.Mathematicians are interested in structures. There is only one way to find the theorems of a structure. Start with an axiom system for the structure and deduce the theorems logically. These axiom systems are the objects of proof-theoretical research. Studying axiom systems there is a series of more or less obvious questions. (shrink)

“Ethical life” is Hegel’s term for the actuality of what Kant calls an “ethical community.” As members of the same ethical community, human beings are related to one another as persons in and only in acting from nothing but respect for the same practical law. Kant and Hegel both take ethical life to be a necessary, nay, the highest, end of pure reason. I argue that this is correct. And I identify the idea of ethical life with the idea of (...) a peculiar form of love. Kant and Hegel disagree—in a curiously reciprocal fashion—about the reach of ethical life and about our capacity to know it to reside within our power: while Kant identifies ethical life with the actuality of the ethical community of all possible human beings, Hegel holds that it is necessarily limited to some particular body politic; and while Hegel thinks that to be a human being is to self-knowingly co-constitute an ethical community, Kant believes that it is to be unable to know oneself to even be apt for this. With Hegel and against Kant, I argue that the only way to have the idea of ethical life is to live it. But with Kant and against a naïve form of Hegelianism, I argue that to be conscious of oneself as a human being, a practically rational animal, is to be conscious of oneself as morally evil, i.e. as actively prone to deeming one’s own particularity the supreme law. I show that this entails Hegelian particularism. And I end by noting that this saddles the Hegelian with the task of demonstrating that ethical particularization belongs to the very idea of pure reason itself, objectively conceived. (shrink)
