If the cortex is an associative memory, strongly connected cell assemblies will form when neurons in different cortical areas are frequently active at the same time. The cortical distributions of these assemblies must be a consequence of where in the cortex correlated neuronal activity occurred during learning. An assembly can be considered a functional unit exhibiting activity states such as full activation (“ignition”) after appropriate sensory stimulation (possibly related to perception) and continuous reverberation of excitation within the assembly (a putative (...) memory process). This has implications for cortical topographies and activity dynamics of cell assemblies forming during language acquisition, in particular for those representing words. Cortical topographies of assemblies should be related to aspects of the meaning of the words they represent, and physiological signs of cell assembly ignition should be followed by possible indicators of reverberation. The following postulates are discussed in detail: (1) assemblies representing phonological word forms are strongly lateralized and distributed over perisylvian cortices; (2) assemblies representing highly abstract words such as grammatical function words are also strongly lateralized and restricted to these perisylvian regions; (3) assemblies representing concrete content words include additional neurons in both hemispheres; (4) assemblies representing words referring to visual stimuli include neurons in visual cortices; and (5) assemblies representing words referring to actions include neurons in motor cortices. Two main sources of evidence are used to evaluate these proposals: (a) imaging studies focusing on localizing word processing in the brain, based on stimulus-triggered event-related potentials (ERPs), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI), and (b) studies of the temporal dynamics of fast activity changes in the brain, as revealed by high-frequency responses recorded in the electroencephalogram (EEG) and magnetoencephalogram (MEG). These data provide evidence for processing differences between words and matched meaningless pseudowords, and between word classes, such as concrete content and abstract function words, and words evoking visual or motor associations. There is evidence for early word class-specific spreading of neuronal activity and for equally specific high-frequency responses occurring later. These results support a neurobiological model of language in the Hebbian tradition. Competing large-scale neuronal theories of language are discussed in light of the data summarized. Neurobiological perspectives on the problem of serial order of words in syntactic strings are considered in closing. Key Words: associative learning; cell assembly; cognition; cortex; ERP; EEG; fMRI; language; lexicon; MEG; PET; word category. (shrink)

A classicist, philosopher, and poet, Poul Martin Møller was an important figure in the Danish Golden Age. The traumatic event of the death of his wife led him to think more profoundly about the question of the immortality of the soul. In 1837 he published his most important philosophical treatise, "Thoughts on the Possibility of Proofs of Human Immortality," presented here in English for the first time. It was read and commented upon by the leading figures of the Golden Age, (...) such as Søren Kierkegaard. It proved to be the last important work that Møller wrote before his death in March of 1838 at the age of 43. (shrink)

Wissenschaft und wissenschaftliche Entwicklung sind zunehmend von Differenzierungen und Spezialisierungen gekennzeichnet, die der Öffentlichkeit immer schwieriger zu vermitteln sind. Dies äußert sich in Bedenken gegenüber der Wissenschaftsfreiheit, wie umgekehrt in Bemühungen, sie als wertvolles Gut der Gesellschaft zu aktualisieren. Freiheit der Wissenschaft ist so Brennpunkt eines Bündels von Problemstellungen und wird hier aus Sicht von Naturwissenschaft, Medizin, Recht, Wissenschaftstheorie und Ethik verhandelt.

Advance directives (ADs) are assumed to reflect the patients’ preferences, even if these are not clearly expressed. Research into whether this assumption is correct has been lacking. This study explores to what extent ADs reflect the true wishes of the signatories.

Friedemann Affolderbach vertritt die These, dass Öffentlichkeit und Gegenöffentlichkeit als wechselseitig aufeinander bezogenes Verhältnis zu interpretieren sind. Entsprechend ist Öffentlichkeit als Deutungszusammenhang sowie Praxis umkämpft und bildet das Spannungsfeld sozialer Bewegungen zur Gewinnung von öffentlichen Erfahrungsräumen. Gegenöffentlichkeit im Sinne einer Demokratie als Lebensform kennzeichnet dabei die Möglichkeiten zur Erweiterung von Erfahrungs- und Experimentierräumen. Ihre Bedeutung besteht darin, Räume für Erfahrungen von Selbstverfügung herauszubilden und erweiterte Handlungsmöglichkeiten in praktische Weltverfügung umzusetzen. Gesellschaftliche Veränderung wird an dieser Stelle als eine öffentliche erfahrbar. (...) Die Herausbildung einer Gegenöffentlichkeit selbst wird als Praxis von Bildung interpretiert und am exemplarischen Beispiel untersucht. (shrink)

Das Erhabene dient Hegel zur asthetischen Beschreibung des Judentums und verdeutlicht die enge Verbindung von Kunst und Religion in seinem Denken. Friedemann Barniske erschliesst Hegels Begriff des Erhabenen vor dem Hintergrund seiner Logik und Symboltheorie, sodass sich theologische Perspektiven fur das moderne Christentum eroffnen. Hegels Asthetik spannt einen religionsgeschichtlichen Bogen u.a. vom alten Indien uber die persische Dichtung und die hebraische Gottesvorstellung des Alten Testaments bis zur christlichen Romantik. Dabei wird jeweils das Zusammenspiel von ideeller Bedeutung und sinnlicher Gestalt (...) zum Kriterium der einzelnen Spielarten von Kunst und Religion. Dem Erhabenen schreibt Hegel die besondere Rolle zu, die Unmoglichkeit eines angemessenen Ausdrucks des Gottlichen zur Sprache zu bringen. Darin liegt auch das Potenzial der Erhabenheit fur das Christentum der Gegenwart. (shrink)

This article offers a functionalist account of trust. It argues that a particular form of trust—Communicated Interpersonal Trust—is paradigmatic and lays out how trust as a social practice in this form helps to satisfy fundamental practical, deliberative, and relational human needs in mutually reinforcing ways. We then argue that derivative (non-paradigmatic) forms of trust connect to the paradigm by generating a positive dynamic between trustor and trustee that is geared towards the realization of these functions. We call this trust’s proleptic (...) potential. Our functionalist approach does not only provide important insights into the practice of trust and its place in the broader web of social life, but also illuminates existing philosophical debates. First, pointing out how opposing theoretical accounts of trust each capitalise on only one of its functions, our paradigm-based approach reveals why they each contain a kernel of truth but are also deficient: the optimal realization of each function is tied to the existence of the other functions as well. Second, we show how a functionalist re-orientation can illuminate two recent disputes regarding (i) the question whether trust is explanatorily two- or three-place and (ii) whether (and to what extent) we can decide to trust others.

The real history of physical chemistry did not begin until 1887, when Svante Arrhenius postulated the existence of ions, Henrik van't Hoff developed the concept of osmosis and Wilhelm Ostwald was appointed professor of physical chemistry at Leipzig university. But already some seventeen years earlier the first chair of physical chemistry had been created, the very chair which was occupied by Ostwald in 1887. The article deals with the circumstances related to this event. The founding of the chair was promoted (...) against famour Leipzig organic chemist Hermann Kolbe by two faculty members. Wilhelm Scheibner and Carl Neumann, both mathematicians, in collaboration with the saxon minister of cultural affairs, von Falkenstein. (shrink)

When is state coercion for the provision of public goods justified? And how should the social surplus of public goods be distributed? Philosophers approach these questions by distinguishing between essential and discretionary public goods. This article explains the intractability of this distinction, and presents two upshots. First, if governments provide configurations of public goods that simultaneously serve essential and discretionary purposes, the scope for justifiable complaints by honest holdouts is narrower than commonly assumed. Second, however, claims to distributive fairness in (...) the provision of public goods also turn out to be more complex to assess. (shrink)

Provides mind-activating methods and practical tools based on Neuro-linguistic Programming and clinical hypnotherapy. Shows how engaging the subconscious mind accelerates healing, growth, and change and allows you to eliminate the root causes of chronic anxiety, depression, and other psychological conditions.

Recent years have witnessed the rise of digital platforms that allow economic agents to arrange ever more fine-grained contracts. This article zooms in on labour-based platforms that permit the hire of labour in a just-in-time fashion (and are part of the broader trend towards on-demand work). Its principal contribution comes in three parts. First, exposing the frequently overlooked diversity of labour-based platforms, the article proposes to distinguish platform companies, which directly sell services and then purchase the labour needed to provide (...) them, and broker platforms, which act merely as intermediaries. Second, it examines how platforms of each type pose distinct threats to labour justice, thereby extending Daniel Halliday's (2021) analysis. Drawing on empirical studies of the experiences of platform workers, it identifies a power imbalance as the root cause of these threats across all platforms. Finally, the article assesses three strategies to counter these threats: introducing stricter regulation, turning platforms into worker-run co-ops, and improving outside job opportunities. In exploring how each strategy could be implemented for specific platforms, it makes the case for always discussing labour-based platforms with one eye to their specific structural features and the other eye to the broader labour market.

Die platonische Teilhabe-Ontologie besitzt in Antike und Mittelalter ein konkretes Potential fur einen philosophisch begrundeten interreligiosen Dialog. Das Buch fuhrt Proklos' Henadenlehre im Kontext seines Teilhabe-Theorems einer schlussigen Interpretation zu und zeigt, wie Nikolaus von Kues das Theorem verwendet, um in seinem Werk "Uber den Frieden im Glauben" u.a. die divergenten Perspektiven von Islam und Christentum auf die Trinitatslehre miteinander zu vermitteln.

Das Buch behandelt das Thema Willensfreiheit und Vorsehung aus Sicht vier verschiedener Autoren. Zunächst werden die philosophischen, nicht vom Kriterium des Bewusstseins abhängigen Willenskonzeptionen des Kirchenvaters Augustinus sowie des Neuplatonikers Proklos erörtert. Mittels erkenntniskritischer Analysen zeigen beide eine Wirklichkeit des Geistigen auf, als deren höchster Urgrund Gott aufscheint. Weder Providenz noch Prädestination sind deterministisch aufzufassen - eine Theodizee erscheint möglich. Ein weiterer Hauptteil zu Apuleius' Goldenem Esel weist die literarische Relevanz des Themas für das Werkganze nach, speziell für eine Lösung (...) des sog. 'Bruchs' zwischen den ersten zehn Büchern und dem Isis-Buch. Abschließend wird dieselbe Thematik in John Miltons Paradise Lost untersucht. (shrink)

This is the first book in English on the major works of the German philosopher Johann Gottlieb Fichte. It examines the transcendental theory of self and world from the writings of Fichte's most influential period, and considers in detail recently discovered lectures on the Foundations of Transcendental Philosophy. At the center of that body of work stands Fichte's attempt to integrate the theories of volition and cognition into a unified but complex 'system of freedom'. The focus of this book is (...) the intricate interplay between thinking and willing in the birth of experience out of the spirit of freedom. Combining incomparable erudition, sensitive readings of some of the most difficult of philosophical texts, clarity in exposition and an acute awareness of historical context this book takes its place as the ideal introduction to Fichte's thought.

Elijah Fenton’s Phaon to Sappho has so far never been in the focus of literary criticism. The article aims at a more detailed understanding of Fenton’s technique of literary reception by means of a close reading of both Phaon to Sappho and Fenton’s model, the Ovidian Epistula Sapphus. As will be seen, Fenton offers an unexpected perspective on the ancient myth through the eyes of ‘his’ Phaon: Phaon did not leave Sappho out of faithlessness but was completely unable to entertain (...) any feelings of true love, because he had been cursed by Venus for being unfaithful to his former girl-friend in Malea. Phaon merely enjoyed Sappho’s gift of song as a temporary remedy for the agony within his cursed mind, but had to leave her whenever she stopped singing. At this point Phaon is asking for Sappho’s intercession with Venus on his behalf. Although Fenton makes crucial changes to the plot, he does neither ‘deconstruct’ nor ‘correct’ the myth as such: instead, he meticulously retains all the major motifs developed in Ovid’s epistle and thus achieves a literary transformation of the myth, enabling the reader to regard either perspective on the two protagonists’ relationship as logically possible.

In his epic Paradise Lost, John Milton aims at a philosophically and theologically sound theodicy in order to “justify the ways of God to men”1. Milton’s approach has been criticised for creating an unsolvable tension between God’s foreknowledge and man’s free will and responsibility. The article wants to show that this criticism turns out to be unjustified if the philosophical basis behind the epic is thoroughly examined. Milton draws heavily on St. Augustine’s ontology: Every kind of being depends on its (...) intrinsic goodness insofar as it really is what it is by nature. God himself is the ultimate goodness: Therefore he is not subject to change, but transcends space and time. In his perfection, he cannot lack any kind of knowledge, but knows all things in an atemporal manner, without depriving men and women of their capability of free choice and action, for these are the distinct features that constitute the goodness of human nature. The crucial question of the article is why, according to Augustine and Milton, God’s foreknowledge should not at all be confused with fated determinism. (shrink)

Tasks in Primary Mathematics Teacher Education is intended to advance relevant research and innovative international practices in the preparation and professional development of mathematics teachers. Emerging from discussion at the ICMI study on teacher professional development, this volume, focused on primary and elementary teachers, culls a richness that can only be found by gathering wisdom from varied experiences around the world. The choice of tasks, and the associated pedagogies, is a key aspect of teaching and learning mathematics. Arguing that what (...) students learn is largely defined by the tasks they are given, several major themes are presented. One such major strand, the form, function and focus of tasks, is discussed throughout several chapters, offering analysis, discussion of implementation, and exemplars of a broader category of illustrative techniques for developing critical understanding.

Neurons repeatedly exposed to similar perceptual experiences fire together and wire together to form ‘meaning kernels’ of concepts. Pulvermueller argues that abstract concepts may be devoid of meaning kernels, because the perceptual experiences that construct abstract concepts are subject to great variation and share few common features. Abstract concept are therefore grounded in the brain through features that belong to ‘meaning halos’, rather than to ‘meaning kernels’.
