Die Gegner der Finalisierungsthese setzen sich in der Regel nur mit dem Projektentwurf der Starnberger Gruppe, nicht mit ihren substantiellen Forschungen, noch viel weniger mit der Sache selbst auseinander, so auch M. Tietzel in Z. f. allg. Wissenschaftstheorie IX, 2, 1978. Als Replik wird deshalb hier ein Stück dieser substantiellen Untersuchungen veröffentlicht: Es geht um die Frage, ob dem Begriff "abgeschlossene Theorie" ein ausweisbarer Sinn gegeben werden kann. Dies wird untersucht durch Analyse der Theoriestruktur der klassischen Hydrodynamik. Hier läßt (...) sich eine systematische Beziehung zwischen der Struktur der Theorie und der empirischen Charakterisierung der Gegenstände, auf die sie sich bezieht , nachweisen. Die Theorie wird also mit Notwendigkeit gültig sein, kann also in diesem Sinne auf der entsprechenden Gegenstandsklasse als abgeschlossen angesehen werden. (shrink)

Werner Heisenberg made an important – and as yet insufficiently researched – contribution to the transformation of the modern conception of science. This transformation involved a reassessment of the status of scientific knowledge from certain to merely hypothetical – an assessment that is widely recognized today. I examine Heisenberg’s contribution in particular by taking his conception of “closed theories” as an example according to which the established physical theories have no universal and exclusive, but only a restricted (...) validity. Firstly, I characterize the historical process of hypothetization of claims to validity. Then, secondly, I reconstruct Heisenberg’s conception, as far as it can be derived from his popular writings, relating it to the process of hypothetization. Finally, I touch on the history of its reception and compare it with conceptions of science that emphasize the significance of the hypothetical for the modern theories of natural sciences. Compared to these conceptions, Heisenberg’s contribution turns out to be rather independent. (shrink)

Werner Heisenberg hat einen wichtigen, noch nicht hinreichend untersuchten Beitrag zum Wandel des neuzeitlichen Wissenschaftsverständnisses geleistet. Der Wandel führte von der Charakterisierung des wissenschaftlichen Wissens als sichere Erkenntnis zu seiner - heute weithin anerkannten - Charakterisierung als bloß hypothetische Erkenntnis. Anfänge dieses Wandlungsprozesses lassen sich im 19. Jahrhundert nachweisen (z.B. bei John Hersehel, William Whewell oder Hermann von Helmholtz). Ich möchte am Beispiel von Heisenberg der Frage nachgehen, welchen Einfluss die Begründung der Quantenmechanik, die seine Wissenschaftsauffassung prägte, auf den Prozess (...) der Relativierung von Geltungsansprüchen hatte. Meine Vermutung ist, dass eine entscheidende Rolle hierbei weniger dem Wahrscheinlichkeitsbegriff als vielmehr dem Wahrheits- und Realitätsbegriff zukam. Ich werde als erstes den historischen Prozess der Hypothetisierung von Geltungsansprüchen, zu dem ich Heisenbergs Konzeption ins Verhältnis setzen möchte, charakterisieren. Anschließend rekonstruiere ich Heisenbergs Konzeption, soweit sie sich seinen populären Reden und Aufsätzen entnehmen lässt. Als drittes werde ich ihre Wirkungsgeschichte kurz ansprechen und sie mit Wissenschaftsauffassungen vergleichen, die die Bedeutung des Hypothetischen für die modernen Theorien der Naturwissenschaften betonen. Ihnen gegenüber erweist sich Heisenbergs Beitrag als durchaus eigenständig. (shrink)

ZusammenfassungNach einer historischen Übersicht über die Entwicklung der naturwissenschaftlichen Disziplinen in den vergangenen Jahrhunderten wird auseinandergesetzt, dass wir seit der Quantentheorie einige frühere Theorien, wie etwa die Newton'sche Mechanik, als abge‐schlossene Theorien bezeichnen. Der Sinn dieser Begriffsbildung wird besprochen, ebenso die Bedingungen, unter denen eine Theorie als abgeschlossen bezeichnet werden kann.

Background Victoria was the first Australian state to legalize voluntary assisted dying (elsewhere known as physician-assisted suicide and euthanasia). Some institutions indicated they would not participate in voluntary assisted dying. The Victorian government issued policy approaches for institutions to consider Objective To describe and analyse publicly available policy documents articulating an institutional objection to voluntary assisted dying in Victoria. Methods Policies were identified using a range of strategies, and those disclosing and discussing the nature of an institutional objection were thematically (...) analysed using the framework method. Results The study identified fifteen policies from nine policymakers and developed four themes: (1) extent of refusal to participate in VAD, (2) justification for refusal to provide VAD, (3) responding to requests for VAD, and (4) appeals to state-sanctioned regulatory mechanisms. While institutional objections were stated clearly, there was very little practical detail in most documents to enable patients to effectively navigate objections in practice. Conclusion This study demonstrates that despite having clear governance pathways developed by centralized bodies (namely, the Victorian government and Catholic Health Australia), many institutions’ public-facing policies do not reflect this guidance. Since VAD is contentious, laws governing institutional objection could provide greater clarity and regulatory force than policies alone to better balance the interests of patients and non-participating institutions.

Background In June 2016, Canada legalized medical assistance in dying (MAiD). From the outset, some healthcare institutions (including faith-based and non-faith-based hospitals, hospices, and residential aged care facilities) have refused to allow aspects of MAiD onsite, resulting in patient transfers for MAiD assessments and provision. There have been media reports highlighting the negative consequences of these “institutional objections”, however, very little research has examined their nature and impact. Methods This study reports on findings from 48 semi-structured qualitative interviews conducted with (...) MAiD assessors and providers, MAiD team members (working to coordinate care and lead MAiD programs in institutions and health authorities), and family caregivers on their experiences with institutional objection. Participants were recruited from the Canadian provinces of British Columbia, Ontario, and Nova Scotia. Data were analyzed using inductive thematic analysis. Results Themes identified were: (1) basis for institutional objection (with objections commonly rooted in religious values and a particular philosophy of palliative care); (2) scope of objection (demonstrating a wide range of practices objected to); (3) lack of transparency regarding institutional position; (4) impacts on patients; (5) impacts on health practitioners; and (6) catalysts for change. Participants reported that many institutions’ objections had softened over time, lessening barriers to MAiD access and adverse impacts on patients and health practitioners. Participants attributed this positive change to a range of catalysts including advocacy by health practitioners and family members, policymaking by local health authorities, education, and relationship building. Nevertheless, some institutions, particularly faith-based ones, retained strong objections to MAiD, resulting in forced transfers and negative emotional and psychological impacts on patients, family members, and health practitioners. Conclusions This paper adds to the limited evidence base about the impacts of institutional objection and can inform practical and regulatory solutions in Canada and abroad. Reform is needed to minimize the negative impacts on patients, their caregivers, and health practitioners involved in MAiD practice. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Anthony Close CENTERING THE DE-CENTERERS: FOUCAULT AND LAS MENINAS Over the last two decades, French avant-garde critical theory has shaken the pillars of the traditionalist temple with this thought: the interpreter of a literary text should not primarily be concerned with its author's intentional design, but rather with the surreptitious forces which shape it, warp it, and ultimately turn it into a problematic will-ofthe -wisp. The "decoding" of those (...) forces takes many forms (Freudian, anthropological, and so on), of which deconstruction is the most celebrated ; "de-centering"—the banishment of the intentional subject from the focus of interpretation — is common to all. In the first part of this article I wish to set out my philosophical objections to that exclusion, and in the second part, to examine an interesting failure to make it effective in practice: Foucault's analysis of Velazquez's painting Las Meninas, which constitutes the first chapter of Les mots et ks choses. One of my reasons for choosing Foucault's text as an example is that its premises are in some ways comparable to the philosophy of the archdeconstructor, Derrida. My skepticism about them and the analytic method based on them is not meant to suggest that I regard Foucault's historical studies as valueless. On the contrary, I recognize that he, together with some other decoders (particularly Barthes), has important things to say. My attack is a form of defense. I wish to uphold the value of traditional forms of interpretation by showing that though Foucault, like other decoders, casts radical doubts upon them in theory, he tends to negate those doubts by the implications of his practice. 21 22Philosophy and Literature M. H. Abrams has defined the traditionalist historian of culture as one who assumes that (a) authors of the past exploited the norms and possibilities of their language to say something determinate, (b) the properly equipped historian can approximate to their meaning, (c) his interpretation can aspire to a reasonable degree of objectivity. ' Let that serve as a working definition of my traditionalist standpoint. This has a philosophical rationale, basically Wittgensteinian and Austinian, which needs to be explained and set over against some of decoding's typical presuppositions. I choose Derrida's as an example. From my perspective, two objections can be leveled against his thought: its tendency to hypostatize the intentional subject as a metaphysical essence which must be reached through and beyond language, and to see language itself as an unrealistically slippery medium. Both objections were raised against him by Searle in their famous polemic with each other.2 Derrida's thought is inscribed within, even while it reacts against, a traditional conception of language as a name-like substitute for essence. According to this conception, influentially represented in this century by Husserl's phenomenology, bits of language somewhat resemble sterling currency bills which bear on their face the legend: "I promise to pay the bearer on demand the sum of? pound(s)" That is, they are potentially capable ofbeing cashed for lumps of being, which can thus be possessed by mind. Derrida counters that the currency is fraudulent: it continually defers presence and possession, rendering problematic its relation to being and self, and their very existence. In order to foster the illusion that he is master of his words, hence of what they designate, Western Man has historically given status of originality to voice rather than to writing, to a form of expression which is seemingly intimate to consciousness rather than external. The paradoxical thesis ofDe lagrammatologie is that writing came first. One of the routes by which Derrida arrives at this conclusion is Saussure's conception of the discontinuous, articulated nature of language and the negative and differential character of linguistic signifiers, not stably linked to universal referents.3 On this basis he builds his idea of différance (a pun on difference and deferral ), the elusive negative margin which makes language possible, and at the same time, makes impossible consciousness's full presence to itself and to being.4 Hence Derrida's notion of language's anarchic and willful power to detach itself from die intentions or usage of its users and to float...

In lieu of an abstract, here is a brief excerpt of the content:Anthony Close THE EMPIRICAL AUTHOR: SALMAN RUSHDIE'S THE SATANIC VERSES HOBBES, comparing the author ofan action to the owner ofgoods, asserts, "And as the right of possession, is called dominion; so the right of doing any action, is called authority" (Leviathan, Book I, chap. 16). My purpose in this essay is to apply this Hobbesian maxim to the relation Author/Text, expanding somewhat Hobbes's notion of authority. I presuppose that (...) in our day-to-day dealings with our fellow men, we envisage each others' acts as exhibiting purpose and commitment, which make them ours in more than the platitudinous sense that we performed them. By virtue of that, they confer on us a privileged, though clearly not unchallengeable, authority in saying what they are and what they are for. Such, in effect, is the position reached by Austin in How to Do Things with Words, and it broadly corresponds to that of various philosophical writings on human action—by Anscombe, Davidson, and Melden.1 To be sure, we may legitimately consider human behavior from other viewpoints (e.g., structuralist, anthropological, psychoanalytical, Marxist) trained on its unconscious presuppositions. Yet, insofar as such theorizing fails to acknowledge the priority of the Hobbesian perspective, it will seem perverse for a reason that has been well put by Charles Taylor. Precisely because history is made up of purposeful activity, Taylor argues, we need to explain historical patterns in a way that is "intelligible in relation to conscious action" even though they may not "issue from conscious action."2 By this criterion much of our modern literary theory is defective. A vivid measure of the deficiency is provided by the furor over Salman Rushdie's TL· Satanic Verses, culminatingin thefatwa pronounced against Philosophy and Literature, © 1990, 14: 248-267 Anthony Close249 him by the Ayatollah Khomeini in February 1989. I take it that for anyone vocationally committed to the practice or study ofliterature and to the cause of freedom of expression, the defense of Rushdie cannot be a matter of indifference. Nor can one be indifferent to the chasm of misunderstanding that separates Rushdie and his apologists from the novel's Muslim opponents. I believe that these two causes—defending Rushdie and bridging the chasm—can be reconciled by offering better explanations ofhis novel in place ofcrude denunciations or, from some non-Muslim quarters, smug and knowing dismissals. Yet, as we shall see, the task of explanation could be considered hamstrung by our modern poetics. I was reminded ofHobbes's textby Rushdie's lucid and cogent defense of his novel in TL· Independent (London, February 4, 1990). Against the accusations that he had deliberately reviled the Islamic faith, he argued as follows. Though TL· Satanic Verses, like many novels that Rushdie esteems, is a work of radical dissent, questioning, and reimagining, it is motivated by a spirit of serious inquiry rather than debunking derision. More particularly, it reflects a determination that underlies all Rushdie's work: "to create a literary language and literary forms in which the experience offormerly-colonised, still-disadvantaged peoples might find full expression." He continues: "It is written from the very experience of uprooting, disjuncture and metamorphosis... that is the migrant condition, and from which, I believe, can be derived a metaphor for all humanity.... [It] celebrates hybridity, impurity, intermingling, the transformation that comes of new and unexpected combinations of human beings, cultures, ideas, politics, movies, songs. It rejoices in mongrelisation and fears the absolutism of the Pure." Note the insistence on how these themes flow direcdy from Rushdie's own experience. Two days after the publication of this article, Harold Pinter gave on Rushdie's behalf a lecture on the relationship of literature to religion and society at the Institute of Contemporary Arts in London. In this lecture, Rushdie articulated a Bakhtinian view of the novelist's function: to dramatize ironically and noncommittally the clash of voices, languages, and ideologies in a world without gods and without traditionsanctioned truth. Rushdie referred specifically, I think, to a species of postmodernist novel which we may dub "palimpsest history";3 the species includes Rushdie's works, García Márquez's One Hundred Years of Solitude, Carlos Fuentes's Terra Nostra...

A book combining theories and practice of ethics in the practice of criminal justice.

Gregor Schiemann führt allgemeinverständlich in das Denken dieses Physikers ein. Thema sind die Erfahrungen und Überlegungen, die Heisenberg zu seinen theoretischen Erkenntnissen geführt haben, die wesentlichen Inhalte dieser Erkenntnisse sowie die Konsequenzen, die er daraus für die Geschichte der Physik und das wissenschaftliche Weltbild gezogen hat. Heisenbergs Vorstellungswelt durchzieht durch ein Spannungsverhältnis, das heute noch das Denken vieler Wissenschaftlerinnen und Wissenschaftler bewegt. Er ist um ein umfassendes Verständnis der Naturprozesse bemüht, zugleich aber von der Berechenbarkeit und Beherrschbarkeit von Phänomenen auch (...) dann schon fasziniert, wenn die zugrunde liegenden Prozesse erst teilweise verstanden sind. Aus der Geschichte der Physik zieht er die wirkungsreiche Lehre, daß sich die naturwissenschaftliche Erkenntnis nicht kontinuierlich, sondern sprunghaft in Form von Revolutionen entwickelt. Die Reichweite des physikalischen Wissens begrenzt er in einer Schichtentheorie der Welt, nach der die komplexen Phänomene des Lebens nicht allein durch die Wechselwirkungen zwischen ihren Bestandteilen erklärt werden können. Der zunehmenden Technisierung der Welt steht Heisenberg kritisch gegenüber. Seiner Zeit weit voraus, glaubt er, daß die Technisierung der Welt eine epochal neue Stufe erreicht habe, in der der Mensch „nur noch sich selbst“ gegenüberstehe. (shrink)

Existing regulation of end-of-life care is flawed. Problems include poorly-designed laws, policies, ethical codes, training, and funding programs, which often are neither effective nor helpful in guiding decision-making. This leads to adverse outcomes for patients, families, health professionals, and the health system as a whole. A key factor contributing to the harms of current regulation is a siloed approach to regulating end-of-life care. Existing approaches to regulation, and research into how that regulation could be improved, have tended to focus on (...) a single regulatory instrument (e.g., just law or just ethical codes). As a result, there has been a failure to capture holistically the various forces that guide end-of-life care. This article proposes a response to address this, identifying “regulatory space” theory as a candidate to provide the much-needed holistic insight into improving regulation of end-of-life care. The article concludes with practical implications of this approach for regulators and researchers. (shrink)

Background Voluntary assisted dying became lawful in Victoria, the first Australian state to permit this practice, in 2019 via the Voluntary Assisted Dying Act 2017 (Vic). While conscientious objection by individual health professionals is protected by the Victorian legislation, objections by institutions are governed by policy. No research has been conducted in Victoria, and very little research conducted internationally, on how institutional objection is experienced by patients seeking assisted dying. Methods 28 semi-structured interviews were conducted with 32 family caregivers and (...) one patient about the experience of 28 patients who sought assisted dying. Participants were interviewed during August-November 2021. Data from the 17 interviews (all with family caregivers) which reported institutional objection were analysed thematically. Results Participants reported institutional objection affecting eligibility assessments, medication access, and taking the medication or having it administered. Institutional objection occurred across health settings and was sometimes communicated obliquely. These objections resulted in delays, transfers, and choices between progressing an assisted dying application and receiving palliative or other care. Participants also reported objections causing adverse emotional experiences and distrust of objecting institutions. Six mediating influences on institutional objections were identified: staff views within objecting institutions; support of external medical practitioners and pharmacists providing assisted dying services; nature of a patient’s illness; progression or state of a patient’s illness; patient’s geographical location; and the capability and assertiveness of a patient and/or caregiver. Conclusions Institutional objection to assisted dying is much-debated yet empirically understudied. This research found that in Victoria, objections were regularly reported by participants and adversely affected access to assisted dying and the wider end-of-life experience for patients and caregivers. This barrier arises in an assisted dying system that is already procedurally challenging, particularly given the limited window patients have to apply. Better regulation may be needed as Victoria’s existing policy approach appears to preference institutional positions over patient’s choice given existing power dynamics. (shrink)

Thematically organized around the major concerns of Basil Bernstein's work as a sociologist, this book includes chapters from some of the leading sociologists and educational scholars. Each section attempts to provide a critical evaluation of Bernstein's work, framed within four interrelated contexts: his sociological theory, sociology of language and code theory, sociology of education and social reproduction, and the influence of his sociology on educational research. In a separate section, Bernstein himself responds to the earlier chapters. The book examines Bernstein's (...) sociology of schools in relation to his general sociological theory and in doing so demonstrates that sociology is an essential lens for understanding the structure and processes of schooling. It also provides a critical evaluation of the strengths and weaknesses of Bernstein's work, as well as a correction to current work in education, which eschews theory in favor of practicality.

In this contribution the socalled Meno-Problem will be discussed. With respect to theories the problem is the following question: Why is it epistemologically more valuable to know a true theory than to simply believe it? A classical answer in reabilist accounts to this problem refers to the value of the operation which is used for gathering knowledge. But there is a gap in the argumentation as far as one is not allowed to derive from this assumption the conclusion that (...) also the result of the operation is valuable. We are going to show a difference between true theories which are just believed and theories which are also known to be true. This difference seems to allow one to close the mentioned gap. (shrink)

Summary Die Kritik am Konzept „abgeschlossener Theorien, die im Kontext der Diskussion um die sogenannte Finalisierungs-These bisher vorgebracht wurde, erweist sich als unhaltbar. Ob die Existenz „abgeschlossener Theorien die Finalisierbarkeit der entsprechenden wissenschaftlichen Disziplinen zur Folge hat, ist eine andere Frage.

Im Gegensatz zu L. v.Bertalanffy, der eine einheitliche biol. Theorie für nicht möglich hält, vertrete ich die These: Eine umfassende biologische Theorie, ausgehend von den Grundlagen der Physik, ist bis dato nicht ausschließbar.Betrachtet man die Frage ‘In welchem Sinne ist eine umfassende physikalische Theorie heute möglich?’, so ergibt sich, daß die Konzipierung je umfassenderer Theorien mit einer Beschränkung des vorhandenen empirischen Satzbestandes einerseits, mit einer Hinzunahme von Regeln für neue empirische Befunde andererseits verbunden ist. Wie am Beispiel einer Schar (...) verschiedenartiger statistischer Mechaniken gezeigt wird, oder wie der an einem experimentell nicht überprüfbaren Wert postulierte Übergang derGalilei- in dieLorentz-Transformation deutlich macht, stellen aufeinanderfolgende, abgeschlossene physikalische Theorien keineswegs Grenzfälle der vorausgehenden Theorien dar.Das unzureichende quantentheoretische Aufbauprinzip der Produkträume zur Konstituierung biol. Systeme weist ebenso wie die Nichtnachprüfbarkeit der Quantentheorie für makrophysikalische Körper auf einen umfassenderen Ansatz hin. Ohne das Hypothetische der einheitlichen Feldtheorie der Elementarteilchen imHeisenbergschen Entwurf zu berühren, erlaubt die nicht lineare Spinortheorie neben der Klassifizierung auch eine Voraussagemöglichkeit, obschon durch diese universelle Grundgleichung die Gesetze in den übrigen Teilen der Physik nicht vollständig bestimmt sind. Gleichwohl bietet dieser Ansatz keinen Schlüssel zur Lösung von Problemen im Grenzbereich zwischen Physik und Biologie.Mehr als das weite Feld biol. Theorien scheinen peinliche Vorurteile biol. Phänomenen gegenüber einer einheitlichen Theorie entgegenzustehen, Vorurteile, ob es sich um die willkürliche Abgrenzung zwischen Mikro- und Makrophänomenen handelt, ob die ungerechtfertigte Gegenüberstellung von qualitativen u. quantitativen Phänomenen im Vordergrund steht, ob ein über das kausale Argumentationsschema hinausgehendes Erklärungsschema gefordert wird, oder ob schließlich die anthropozentrischen Begriffsbildungen sowie die emotional bedingten Wesensfragen Platz greifen.Dessen ungeachtet stellen die Lebenserscheinungen ebenso wie die Verhaltenskombinate Mechanismen dar und sind durch Gesetze beschreibbar. Daher kann eine universelle Grundgleichung unter Hinzunahme weiterer, d.h. über den Bereich des Physikalischen hinausgehenden, empirischer Regeln nicht ausgeschlossen werden. In diesem Sinne ist eine umfassende biol. Theorie, ausgehend von den Grundlagen der Physik, möglich, ohne daß diese These eine Reduktion der Biologie auf die Physik zur Folge hätte. (shrink)

The aim of this paper is to examine in detail the similarities and dissimilarities between Werner Heisenberg’s account of closed theories and Thomas Kuhn’s model of scientific revolutions. My analysis draws on a little‐known discussion that took place between Heisenberg and Kuhn in 1963, in which Heisenberg, having just read Kuhn’s Structure of Scientific Revolutions, compares Kuhn’s views to his own account of closed theories. I conclude that while Heisenberg and Kuhn share a holist conception of (...) theories, a revolutionary model of theory change, and even a notion of incommensurability, their views diverge fundamentally when it comes to the issue of scientific realism. I show that, contrary to popular opinion, Heisenberg is not an instrumentalist, but rather a pluralistic realist. (shrink)

In this paper we discuss the representational realist stance as a pluralist ontic approach to inter-theoretic relationships. Our stance stresses the fact that physical theories require the necessary consideration of a conceptual level of discourse which determines and configures the specific field of phenomena discussed by each particular theory. We will criticize the orthodox line of research which has grounded the analysis about QM in two metaphysical presuppositions —accepted in the present as dogmas that all interpretations must follow. We (...) will also examine how the orthodox project of "bridging the gap" between the quantum and the classical domains has constrained the possibilities of research, producing only a limited set of interpretational problems which only focus in the justification of "classical reality" and exclude the possibility of analyzing the possibilities of non-classical conceptual representations of QM. The representational realist stance introduces two new problems, namely, the superposition problem and the contextuality problem, which consider explicitly the conceptual representation of orthodox QM beyond the mere reference to mathematical structures and measurement outcomes. In the final part of the paper, we revisit, from a representational realist perspective, the quantum to classical limit and the orthodox claim that this inter-theoretic relation can be explained through the principle of decoherence.

I claim that Heisenberg’s notion of a closed theory and its analysis by Erhard Scheibe fit well with the philosophy of later Wittgenstein or its generalization. The notion of a closed theory corresponds to the notions of a form of life and rule/concept. I suggest the possibility of reconciling the views of Heisenberg, Dirac, and Bohr about inter-theoretical relations within a rational naturalistic pragmatism à la Wittgenstein and Robert Brandom’s analytic interpretation of Kantian synthetic unity of apperception. In (...) particular, I explain why a “closed theory” is “closed”, “accurate” (and even “perfect”), and “final” (as Heisenberg claims), and why it is also “open” and “approximate” in Dirac’s sense. That being said, unlike Alisa Bokulich (2004, 2006, 2008), I rather favour Heisenberg’s philosophical position. (shrink)

I interpret the philosophical views of Werner Heisenberg as a pragmatism and non-metaphysical realism of a Wittgensteinian kind. The “closed theory” is a Wittgensteinian rule/concept.

After indicating why this is needed, the paper proves a non-triviality result for paraconsistent theory containing arithmetic, naive truth and denotation predicates, and descriptions. The result is obtained by dualising a construction of Kroon. Its most notable feature is that there is a trivial object- one that has every property.

Der Streit um die Prinzipien der Theorienentwicklung hat in den Jahren seit dem Erscheinen von TH. S. KUHNS "Die Struktur wissen schaftlicher Revolutionen" mannigfache und lebhafte AufSerungen pro und contra hervorgerufen. Die Gegenposition wird im wesent lichen durch die Namen POPPER und LAKATOS charakterisiert. Die Kontroverse erweist sich als eine solche zwischen synchronischer und diachronischer, zwischen systematischer und historischer Betrach tungsweise. 1st die Entwicklung der Wissenschaften, wie man es nach KUHN glauben kann, in entscheidendem MafSe aufSeren Einfliissen und Zufalligkeiten ausgesetzt, (...) oder gibt es nicht doch rationale, rein wissenschaftsimmanente Kriterien, auf Grund derer eine Entwicklung im Sinne eines Fortschrittes zu immer besseren, richtigeren und lei stungsfahigeren Theorien moglich ist?

Die Bewertung einer Theorie im Sinne ihrer Richtigkeit ist bisher nicht gelungen. Wenn POPPER, insbesondere in seinen spaten Arbeiten ("Objective Knowl edge"), die Auffassung vertritt, dafS die Entwicklung der Wissen schaften im Sinne einer immer grofSeren Wahrheitsahnlichkeit von statten gehe, so ist das bei ihm ein reiner Glaube, der auf Grund seines Modells von Versuch und Irrtum postuliert wird.

Closed Material Procedures are widely considered to be unjust. In his influential A Theory of Justice, Rawls sets out that trials must be fair and open, and that such precepts of natural justice ensure the impartiality of the legal order. I argue that whilst this commits Rawls to a rejection of the permissibility of CMPs, he is not right to do so, and his theory does not require him to do so. Firstly, the conception of natural justice upon which (...) Rawls bases his view of open justice is not so strict as to demand this so long as the legal system ensures a sufficient gist of the closed material is provided. Secondly, it is plausible that individuals in Rawls’ original position, would select CMPs due to the role security and stability play in a just state, the importance of which Rawls explicitly recognises. I conclude that CMPs are consistent with Rawls’ theory of justice, despite his assertions in A Theory of Justice. Given the importance and influence of Rawls’ theory, this is an important step in demonstrating the permissibility of such procedures, duly circumscribed. (shrink)

A widely accepted theory holds that emotional experiences occur mainly in a part of the human brain called the amygdala. A different theory asserts that color sensation is located in a small subpart of the visual cortex called V4. If these theories are correct, or even approximately correct, then they are remarkable advances toward a scientific explanation of human conscious experience. Yet even understanding the claims of such theories—much less evaluating them—raises some puzzles. Conscious experience does not present (...) itself as a brain process. Indeed experience seems entirely unlike neural activity. For example, to some people it seems that an exact physical duplicate of you could have different sensations than you do, or could have no sensations at all. If so, then how is it even possible that sensations could turn out to be brain processes? (shrink)

This paper takes as a starting point William Ophul's claim that the last 450 years amount to an 'era of exception' in terms of resource availability. Ophuls suggests that it is no accident that this exceptional era of abundance coincides with the birth and development of liberalism - that liberalism, in other words, would not/could not have occurred without the conditions provided by this era of exception. Some of the ways in which this suggestion might be critically examined are discussed, (...) and attention is drawn to one of its more interesting implications: if liberalism depends on abundance, what kind of political theory do we need if we are entering a new era of scarcity ('peak oil/peak everything')?

In Dellunde et al. 997–1015), we determined the complete theory Te of modules of separably closed fields of characteristic p and imperfection degree e, eω{∞}. Here, for 0≠eω, we describe the closed set of the Ziegler spectrum corresponding to Te. Further, we establish a correspondence between certain submodules and n-types and we investigate several notions of dimensions and their relationships with the Lascar rank. Finally, we show that Te has uniform p.p. elimination of imaginaries and deduce uniform weak (...) elimination of imaginaries. (shrink)

We show that there is a computable procedure which, given an ∀∃-sentence ${\varphi}$ in the language of the partially ordered sets with a top element 1 and a bottom element 0, computes whether ${\varphi}$ is true in the Medvedev degrees of ${\Pi^0_1}$ classes in Cantor space, sometimes denoted by ${\mathcal{P}_s}$.

We generalize to theories of modules (complete or not) a result of U. Felgner stating that a complete theory of abelian groups is a Horn theory if and only if it is closed under products. To prove this we show that a reduced product of modules $\Pi_F M_i (i \in I)$ is elementarily equivalent to a direct product of ultraproducts of the modules $M_i (i \in I)$.

Several theories of consciousness first described about a decade ago, including the conscious electromagnetic information (CEMI) field theory, claimed that the substrate of consciousness is the brain’s electromagnetic (EM) field. These theories were prompted by the observation, in many diverse systems, that synchronous neuronal firing, which generates coherent EM fields, was a strong correlate of attention, awareness, and consciousness. However, when these theories were first described there was no direct evidence that synchronous firing was actually functional, rather (...) than an epiphenomenon of brain function. Additionally, any EM field-based consciousness would be a ‘ghost in the machine’ unless the brain’s endogenous EM field is also able to influence neuron firing. Once again, when these theories were first described, there was only indirect evidence that the brain’s EM field influenced neuron firing patterns in the brain. In this paper I describe recent experimental evidence which demonstrate that synchronous neuronal firing does indeed have a functional role in the brain; and also that the brain’s endogenous EM field is involved in recruiting neurons to synchronously firing networks. The new data point to a new and unappreciated form of neural communication in the brain that is likely to have significance for all theories of consciousness. I describe an extension of the CEMI field theory that incorporates these recent experimental findings and integrates the theory with the ‘communication through coherence’ hypothesis. (shrink)

We consider the reduct to the module language of certain theories of fields with a non surjective endomorphism. We show in some cases the existence of a model companion. We apply our results for axiomatizing the reduct to the theory of modules of non principal ultraproducts of separably closed fields of fixed but non zero imperfection degree.

It is well‐known that the theory of algebraically closed fields is not finitely axiomatizable. In this note, we prove that the theory of integrally closed integral domains is also not finitely axiomatizable.

For the classA of uncountable Archimedian real closed fields we show that the statement “TheL <ω-theory ofA is complete” is independent of ZFC. In particular we have the following results:Assuming the Continuum-Hypothesis (CH) is incomplete. Conversely it is possible to build a model of set theory in which is complete and decidable. The latter can also be deduced from the Proper Forcing Axiom (PFA). In this case turns out to be equivalent to the elementary theory of the real numbers (...)

In der Ein-leitung der Untersuchung werden jedoch auch ältere Theorien der Metapher vorgestellt, die aus der Perspektive der metaphorischen Bedeutung relevant sind oder als relevant be-trachtet werden können. Allen diesen Theorien liegt die Definition zugrunde, dass in der Metapher etwas als etwas anderes gesehen wird. Daher kann von einer Wahrnehmungs-metaphorik die Rede sein. Das erste Kapitel meiner Arbeit behandelt (...) die Frage, wie Metaphern in der Sprache zu erkennen sind. Es wird die Schlussfolgerung gezogen, dass eine Metapher, anstatt erkannt zu werden, vielmehr als solche akzeptiert werden muss. Im zweiten Kapitel werden zwei der bedeutsamsten zeitgenössischen Theorien der Metapher, nämlich von Max Black und Donald Davidson, erörtert und kritisch ausgewertet. Der Argumentation Davidsons zufolge muss die metaphorische Bedeutung als etwas All-gemeines verstanden werden, das nicht einer bestimmten Metapher, sondern der Metapher überhaupt zukommt. Dabei bleibt Davidson aber der Wahrnehmungs-metaphorik verhaftet, die bei ihm wie bei Black keine Erläuterung findet. Gegen Ende des zweiten Kapitels und hauptsächlich im dritten Kapitel werden drei Arten des Herangehens an die Wahrnehmungsmetaphorik vorgeschlagen: Sie kann entweder verworfen oder interpretiert oder aufgehoben werden. Die zwei letztgenannten Zugänge werden anhand der Schriften von Ludwig Wittgenstein, José Ortega y Gasset und Wallace Stevens weiter ausgearbeitet. -/- Abstract: This thesis investigates the concept of the metaphorical meaning originating in analytical philosophy. Also, in the Introduction are considered older theories of the meta-phor, which can be seen from the perspective of the metaphorical meaning. All these ac-counts are based on a definition that in the metaphor is something seen as something else. Therefore, all our understanding of the metaphor issues from a visual perception. But that’s a metaphor, too. Chapter I. examines the question, how to detect metaphors in lan-guage. It is concluded that metaphors must be accepted instead of detected. The chapter II. aims at introducing and criticizing the two nowadays prominent analytical theories of metaphor given by Max Black and Donald Davidson. The consequence of the argumenta-tion by Davidson is that the concept of the metaphorical meaning has to be applied to the metaphor as such, not to any particular one. In their theories, Davidson and Black are still likening the metaphor to the visual perception but this simile or rather metaphor remains unexplained. The final chapter III. presents three approaches how to deal with the visual perception metaphor in explanations of the metaphor: it can be rejected, interpreted or sublated. The last approaches are elaborated on the basis of writings by Ludwig Wittgen-stein, José Ortega y Gasset and Wallace Stevens. (shrink)

In this paper we give a new proof of the characterization of the closed fragment of the provability logic of Heyting's Arithmetic. We also provide a characterization of the closed fragment of the provability logic of Heyting's Arithmetic plus Markov's Principle and Heyting's Arithmetic plus Primitive Recursive Markov's Principle.
