We present a model of computation for string functions over single-sorted, total algebraic structures and study some basic features of a general theory of computability within this framework. Our concept generalizes the Blum-Shub-Smale setting of computability over the reals and other rings. By dealing with strings of arbitrary length instead of tuples of fixed length, some suppositions of deeper results within former approaches to generalized recursion theory become superfluous. Moreover, this gives the basis for introducing computational complexity in a BSS-like (...) manner. Relationships both to classical computability and to Friedman's concept of eds computability are established. Two kinds of nondeterminism as well as several variants of recognizability are investigated with respect to interdependencies on each other and on properties of the underlying structures. For structures of finite signatures, there are universal programs with the usual characteristics. For the general case of not necessarily finite signature, this subject will be studied in a separate, forthcoming paper. (shrink)

The aim of the paper is to present and evaluate Bolzano's theory of grounding, that is, his theory of the concept expressed and the relation brought into play by 'because'. In the first part of the paper (Sections 1-4) the concept of grounding is distinguished from and related to three other concepts: the concept of an epistemic reason}, the concept of causality, and the concept of deducibility (i.e., logical consequence). In its second part (Sections 5-7) Bolzano's positive account of grounding (...) is reconstructed in axiomatic form and critically discussed. (shrink)

I critically discuss a recent innovation in the debate surrounding the plausibility of rational choice theory : the appeal to evolutionary theory. Specifically, I assess Gigerenzer and colleagues’ claim that considerations based on natural selection show that, instead of making decisions in a RCT-like way, we rely on ‘simple heuristics’. As I try to make clearer here, though, Gigerenzer and colleagues’ arguments are unconvincing: we lack the needed information about our past to determine whether the premises on which they are (...) built are true—and, hence, we cannot tell whether they, in fact, speak against RCT.

Far-reaching promises made by nanotechnology have raised the question of whether we are on the way to understanding human beings more and more as belonging to the realm of technology. In this paper, an increasing need to understand the technological re-conceptualization of human beings is diagnosed whenever increasingly “technical” interpretations of humans as mechanical entities are disseminated. And this can be observed at present in the framework of nanobiotechnology, a foremost “technical” self-description where a technical language is adopted. The arena (...) in which the decision is made on increasing the use of technological understanding to define mankind will not be found in the surgery room in which one works with implants, nor the NBIC-laboratory, in which “nerve plugs” are supposed to be developed. The thesis of this paper is that such arena is rather related to the manner in which concepts of humanity are associated with it, how we think and talk about ourselves, and which consequences we draw out of it.

Parallel to the public discussion on the benefits and risks of nanotechnology, a debate on the ethics of nanotechnology has begun. It has been postulated that a new “nano-ethics” is necessary. In this debate, the — positive as well as negative — visionary and speculative innovations which are brought into connection with nanotechnology stand in the foreground. In this contribution, an attempt is made to discover new ethical aspects of nanotechnology in a more systematic manner than has been the case. (...) It turns out that there are hardly any completely new ethical aspects raised by nanotechnology. It is much rather primarily a case of gradual shifts of emphasis and of relevance in questions which, in principle, are already known and which give reason for ethical discussions on nanotechnology. In a certain manner, structurally novel ethical aspects arise through the important role played by visions in the public discourse. New questions are also posed by the fact that previously separate lines of ethical reflection converge in the field of nanotechnology. The proposal of an independent “nano-ethics”, however, seems exaggerated. (shrink)

Confabulations are memories of events and experiences that have never actually happened. Such false memories have fascinated scientists for over a century, and in recent years been the subject of much debate. This is the first book to provide an in-depth analysis of an extraordinary and controversial subject.

In the wake of the emergence and rapid development of nanoethics there swiftly followed fundamental criticism: nanoethics was said to have become much too involved with speculative developments and was concerning itself too little with actually pending questions of nanotechnology design and applications. If this diagnosis is true, then large parts of nanoethics are misguided. Such fundamental criticism must surely either result in a radical reorientation of nanoethics or be refuted for good reasons. In this paper, I will examine the (...) critics’ central arguments and, building on this scrutiny, formulate an answer to these alternatives. The results lead to conclusions which allow explaining and unfolding the thesis of this paper that instead of speculative nanoethics we should better speak of and develop explorative philosophy of nanotechnology.

Finding out why we have beliefs and desires is important for a thorough understanding of the nature of our minds (and those of other animals). It is therefore unsurprising that several accounts have been presented that are meant to answer this question. At least in the philosophical literature, the most widely accepted of these are due to Kim Sterelny and Peter Godfrey-Smith, who argue that beliefs and desires evolved due to their enabling us to be behaviourally flexible in a way (...) that reflexes do not—which, they claim, is beneficial in epistemically complex environments. However, as I try to make clear in this paper, upon closer consideration, this kind of account turns out to be theoretically implausible. In the main, this is because it fails to give due credit to the powers of reflex-driven organisms, which can in fact be just as flexible in their behaviour as ones that are belief/desire-driven. In order to improve on this account, I therefore propose that beliefs and desires evolved, not due to their enabling us to do something completely different from what reflexive organisms can do, but rather due to their enabling us to do the same things better. Specifically, I argue that beliefs and desires evolved for making the generation of behaviour more efficient, since they can simplify the necessary cognitive labour considerably. I end by considering various implications of this account. (shrink)

This book is the first systematic treatment of the philosophy of science underlying evolutionary economics. It does not advocate an evolutionary approach towards economics, but rather assesses the epistemic value of appealing to evolutionary biology in economics more generally. The author divides work in evolutionary economics into three distinct, albeit related, forms: a structural form, an evidential form, and a heuristic form. He then analyzes five examples of work in evolutionary economics falling under these three forms. For the structural form, (...) he examines the parallelism between natural selection and economic decision making, and the parallelism between natural selection and market competition. For the evidential form, he looks at the relationship between animal and human economic decision making, and the evolutionary explanation of diversity in human economic decision making. Finally, for the heuristic form, he focuses on the plausibility of equilibrium modeling in evolutionary ecology and economics. In this way, he shows that linking evolutionary biology and economics can make for a powerful methodological tool that can enable progress in our understanding of various economics questions. Structure, Evidence, and Heuristic will be of interest to scholars and advanced students working in philosophy of science, philosophy of social science, evolutionary biology, and economics. (shrink)

In their book Unto Others, Sober and Wilson argue that various evolutionary considerations (based on the logic of natural selection) lend support to the truth of psychological altruism. However, recently, Stephen Stich has raised a number of challenges to their reasoning: in particular, he claims that three out of the four evolutionary arguments they give are internally unconvincing, and that the one that is initially plausible fails to take into account recent findings from cognitive science and thus leaves open a (...) number of egoistic responses. These challenges make it necessary to reassess the plausibility of Sober & Wilson’s evolutionary account—which is what I aim to do in this paper. In particular, I try to show that, as a matter of fact, Sober & Wilson’s case remains compelling, as some of Stich’s concerns rest on a confusion, and those that do not are not sufficiently strong to establish all the conclusions he is after. The upshot is that no reason has been given to abandon the view that evolutionary theory has advanced the debate surrounding psychological altruism. (shrink)

The role of normative reflection and the possibilities of ethical inquiry in technology assessment have been under discussion in the TA community for several years. As an outcome of this discussion the necessity of explicitly dealing with normativity in TA has widely been acknowledged. However, it is still quite unclear in which way this should be done. This paper is dedicated to the role (and limitations) of ethical expertise in this field, especially in HTA. By methodological analysis an approach is (...) developed to show how entry points for ethical expertise could be identified. The result is that ethical expertise can inform moral debates by uncovering underlying assumptions, by making the normative structure of argumentation transparent, and by weighing the strength of the arguments. In this way moral debates in HTA can become more transparent and opened to argumentative reasoning instead of consisting of bargaining processes determined by power distributions. Ethical reflection, however, does not replace decision-making. (shrink)

Moral Sanctuary is used in this paper as a metaphor for any theory which makes actions immune from moral criticism. Three arguments favoring moral sanctuaries for business activities are countered. Two of the arguments rest on faulty analogies. One compares business activities to games, another to the behavior of machines. The third rests on the claim that business is a unique activity. This position is rejected by a reductio ad absurdum argument; it entails the immunity of all professional activities from (...) moral judgment. I argue that business managers are accountable to the combined requirements of professionalism and democratic citizenship, notions which are briefly described at the conclusion of the paper.

Several authors have recently argued that the excessive focus on equilibrium models in mainstream economic analysis prevents economists from providing accurate representations of the complex and dynamic nature of real economic systems. In response, this paper argues the following. Many economic systems are the products of deliberate and centralized human design. People can and do build and support structures, such as social institutions, aiming to enhance the predictability of economic systems, and thus to move them toward being equilibrium systems. This (...) provides a reason to think that many economic systems can be represented by equilibrium models. (shrink)

Notions of democracy and nationhood constitute the pivotal legacy of the American Revolution, but to understand their development one must move beyond a purely American context. Citizens of a Common Intellectual Homeland explores the simultaneous emergence of modern concepts of democracy and the nation on both sides of the Atlantic during the age of revolutions. Armin Mattes argues that in their origin the two concepts were indistinguishable because they arose from a common revolutionary impulse directed against the prevailing hierarchical (...) political and social order. The author shows how the reconceptualization of democracy and the nation, which resulted from this revolutionary impulse, received its decisive form from the French Revolution. Although the French Revolution was instrumental in redefining the two terms, however, neither were these changes confined to France, nor did the new meanings merely radiate from France to other countries. To illustrate the transatlantic emergence of these ideas, Mattes considers the works of pairs of prominent intellectual contemporaries--one in America and the other in Europe--each writing on a common topic. The thinkers and topics include Thomas Paine and Edmund Burke on the transatlantic revolutions, John Adams and Friedrich von Gentz on the mixed constitution, James Madison and Immanuel Kant on perpetual peace, and Thomas Jefferson and Destutt de Tracy on the nation. Mattes's approach highlights the significant impact that the French Revolution had on the evolution of thought in the period, demonstrating that the emergence and early development of modern concepts of democracy and the nation in America were intimately tied to revolutionary events and processes in the larger Atlantic world. Preparation of this volume has been supported by the Thomas Jefferson Foundation. Jeffersonian America. (shrink)

Der Band gibt erstmals einen umfassenden Überblick über den lyrischen Nachlass des jungen Nietzsche aus den 1850er und -60er Jahren. Zusätzlich präsentiert Armin Thomas Müller eine Beispiel-Edition und historisch kontextualisierende Analyse des Manuskripthefts Mp I 22 von 1858. Somit trägt der Band grundlegend zur literatur-, philosophie- wie kulturgeschichtlichen Auseinandersetzung mit Nietzsche bei. Armin Thomas Müllers Arbeit nimmt den bislang in der literaturwissenschaftlichen wie auch philosophischen Auseinandersetzung mit Friedrich Nietzsche vernachlässigten lyrischen Nachlass aus der Zeit zwischen 1850 und 1869 (...) in den Blick. Anschließend an eine grundlegende Einführung in das Thema wird Nietzsches Jugendlyrik überblicksartig vorgestellt mit Schwerpunkten zur Editions- und Forschungsgeschichte, zu literaturgeschichtlichen Kontexten sowie zu den autoreflexiven Aufzeichnungen des jungen Nietzsche, die das Thema (lyrischer) Dichtung umkreisen. Die vorliegende Publikation enthält zudem eines heutigen materialorientierten Standards entsprechende Faksimile-Edition mit diplomatischer Transkription des Manuskripthefts Mp I 22 von 1858. Das kulturgeschichtliche Erkenntnispotenzial in Nietzsches Jugendgedichten wird abschließend in einer textgenetischen und historisch kontextualisierenden Analyse der edierten lyrischen Texte aus Mp I 22 deutlich. Auf dieser Grundlagenforschung werden weiterführende Auseinandersetzungen mit Nietzsche aufbauen können. (shrink)

Handling the impacts and consequences of technology has become a problem of political, social and scientific relevance since the Sixties. The earlier assumption that technological evolution would automatically lead to social and human progress in an emphatic sense can no longer be sustained. The ambivalence of technology has become a standing topic in the public, philosophical and scientific debate .In this situation new challenges to technology policy are emerging. Functions of an `early warning' with respect to the risks or potentials (...) of new technologies or to ways of avoiding or, at least, resolving technology conflicts by compromise have been postulated . Technology policy pursued by parliament or government, therefore, is in need of scientific consultation . Since the Seventies a number of institutions in this field have been founded , either primarily as parliamentary bureaus of knowledge-transfer to the decision-makers , as networks with a low degree of institutionalization or as independent scientific institutes .The scientific discussion on how to acquire and establish orientational knowledge for decision-makers facing the ambivalence of technology is sectoralized into two branches: the ethics of technology and technology assessment . These two branches are based on fundamentally different assumptions concerning how to give orientation to technology policy: the philosophical ethics, of course, emphasizes the normative implications of decisions on technology and the importance of moral conflicts , while technology assessment relies mainly on sociological or economic research .Both approaches have largely been developed and practised without regard to one another. In Germany, at the beginning of the Nineties the conceptual discussion around these questions was initiated. At first, a lot of misunderstandings appeared, both parties fundamentally criticizing each other, often one denying the competence of the other to deal appropriately with technology problems . In this paper the conflict is analyzed by looking at the situation in Germany, summarizing and weighing the main arguments which have been brought up by TA and the ethical approach to technology.As a result it will be shown that both are partly right, whereby the relative weight of both approaches in their capacity to give orientation is dependent on contextual circumstances. A non-reductionistic overall approach must take into account the normative aspects of the ethics of technology when handling moral conflicts as well as the need for operationalization, concreteness and established knowledge about the processes of “managing technology in society” postulated by TA.

Business schools have become implicated in the widespread demonisation of the financial classes. By educating those held most responsible for the crisis – financial traders and speculators – they are said to have produced ruthlessly talented graduates who have ambition in abundance but little sense for social responsibility or ethics. This ethical lack thrives upon the trading floor within a compelling critique of the complicity of the pedagogy of the business school with the financial crisis of the global economy. An (...) ethical turn within the curriculum is now widely encouraged as a counteractive force. Within this paper, however, we argue that taking this ethical turn is not enough. For business ethicists to learn from the financial crisis, the crisis' legacy needs to be taken account of, and financialisation needs to be taken seriously. Pedagogical reform cannot bracket itself off from the crisis as if it were coincidental with or separate from it. Post-crisis pedagogy must rather take the fact that it is requested now, in light of the crisis, as its very point of departure. The financial crisis must not be understood as something to be resisted in the name of Business Ethics. Instead, the financial crisis must be understood as the very foundation for contemporary Business Ethics in particular and for contemporary business and management education more generally. (shrink)

In modern societies there is an increasing need for orientation in dealing with challenges resulting from scientific progress. At present, that can be observed in the field of converging technologies which shall enable human enhancement. In providing prospective knowledge and assessments to meet the need for orientation an entry point for naturalistic ideas will be uncovered. It consists in considering knowledge about societal developments analogously to knowledge about natural processes as causal knowledge. This, however, implies a causalistic understanding of society (...) which will be critisized. (shrink)

Based on the computation mode introduced in [13], we deal with the time complexity of computations over arbitrary first-order structures.The main emphasis is on parameter-free computations. Some transfer results for solutions of P versus NP problems as well as relationships to quantifier elimination are discussed. By computation tree analysis using first-order formulas, it follows that P versus NP solutions and other results of structural complexity theory are invariant under elementary equivalence of structures.

The topological arithmetical hierarchy is the effective version of the Borel hierarchy. Its class Δta 2 is just large enough to include several types of pointsets in Euclidean spaces ℝ k which are fundamental in computable analysis. As a crossbreed of Hausdorff's difference hierarchy in the Borel class ΔB 2 and Ershov's hierarchy in the class Δ0 2 of the arithmetical hierarchy, the Hausdorff-Ershov hierarchy introduced in this paper gives a powerful classification within Δta 2. This is based on suitable (...) characterizations of the sets from Δta 2 which are obtained in a close analogy to those of the ΔB 2 sets as well as those of the Δ0 2 sets. A helpful tool in dealing with resolvable sets is contributed by the technique of depth analysis. On this basis, the hierarchy properties, in particular the strict inclusions between classes of different levels, can be shown by direct constructions of witness sets. The Hausdorff-Ershov hierarchy runs properly over all constructive ordinals, in contrast to Ershov's hierarchy whose denotation-independent version collapses at level ω 2. Also, some new characterizations of concepts of decidability for pointsets in Euclidean spaces are presented. (shrink)

The role of ethics in technology development has been often questioned, especially in the early days of societal reflection of technology. However, the situation has changed dramatically. Ethical consideration now is generally declared to be indispensable in shaping technology in a socially acceptable and sustainable way. The expectations of ethics are large; often even a kind of “New Ethics” is postulated. In the present paper an over-estimation of the role of ethics for technology development is rejected. It is argued that (...) ethical reflection is, indeed, indispensable in certain problem areas and situation types; but there is, on the other hand, space for technology development free from the requirement for ethical reflection. The absence of a requirement for ethical reflection, however, always has to be considered relative to some “morale provisoire” (provisional morality) as an accepted normative framework within which technology development may occur without explicit ethical reflection. If this framework, however, is doubted or is shown to be insufficient the situation changes completely. Ethical reflection in this case becomes necessary, to consider this normative framework in order to offer modifications or supplements. (shrink)

Questions can be raised about the central status that evolutionarily ancient core knowledge systems are given in Spelke's otherwise very compelling theory. So, the existence of domain-general learning capacities has to be admitted, too, and no clear reason is provided to doubt the existence of uniquely human cognitive adaptations. All of these factors should be acknowledged when explaining human thought.

Antonio Gramsci - mit diesem Namen assoziieren wir zunächst ein philosophisches Modell, sprach- und kulturtheoretische Analysen, Gesellschaftskritik, emanzipatorische Politikvorstellungen. Weniger bekannt ist die pädagogische Grundlinie, die sich durch die gesamte theoretische und praktische Tätigkeit des italienischen Philosophen zieht. Die vorliegende Studie erschließt die pädagogische Vorstellungswelt und die Bildungsmodelle Gramscis sowohl im Sinne einer geschichtlichen Rekonstruktion, als auch im Hinblick auf ihre Gegenwarts- und Zukunftsrelevanz. Analysiert werden Gramscis pädagogische und bildungspolitische Überlegungen vor der Inhaftierung sowie die in den Gefängnisschriften und -heften (...) vorgenommenen erziehungs- und bildungstheoretischen Reflexionen. Zugleich wird die Frage aufgegriffen, wie Gramscis Bildungs- und Erziehungsvorstellungen heute weiterzudenken wären und welche Bereicherung in seinem Denken für eine emanzipative Erziehungswissenschaft liegt. - Armin Bernhard, Jg. 1957, ist Professor für Allgemeine Pädagogik am Fachbereich Bildungswissenschaften der Universität Duisburg-Essen, Standort Essen.

Dynamic stability of the knee and weakness of the extensor muscles are considered to be the most important functional limitations after anterior cruciate ligament injury, probably due to changes at the central level of motor control rather than at the peripheral level. Despite general technological advances, fewer contraindicative surgical procedures, and extensive postoperative rehabilitation, up to 65% of patients fail to return to their preinjury level of sports, and only half were able to return to competitive sport. Later, it becomes (...) clear that current rehabilitation after knee surgery is not sufficient to address the functional limitations after ACL reconstruction even years after surgery. Therefore, new therapeutic tools targeting the central neural system, i.e., the higher centers of motor control, should be investigated and integrated into current rehabilitation practice. To improve motor performance when overt movement cannot be fully performed, several techniques have been developed to increase physical and mental activation without the need to perform overt movements. Among the most popular cognitive techniques used to increase physical performance are motor imagery and action observation practices. This review, which examines the available evidence, presents the underlying mechanisms of the efficacy of cognitive interventions and provides guidelines for their use at home. (shrink)

There are different possibilities for defining the areas for the application of ethics to engineering. They range from descriptive analysis of engineers’ relationship to moral criteria and extend to normative issues on how engineers should design more “sustainable” technology. In this paper, a frame of reference is proposed, which makes it possible to elaborate in a transparent manner goals for analysis of the scope of ethics in engineering. Its point of departure is marked by two questions: 1) which types of (...) situation in the practice of engineering require ethical reflection? and 2) to what extent are engineers expected to assume moral responsibility in the practice of their profession? The answers to both of these questions presuppose reflection on the societal processes of setting definitions and of making ascriptions. Understanding these processes of societal “construction” of demands for ethical reflection in engineering and of engineers’ moral responsibilities should be an important objective of the analysis of ethics in engineering.

A number of scholars have recently defended the claim that there is a close connection between the evolutionary biological notion of fitness and the economic notion of utility: both are said to refer to an organism’s success in dealing with its environment, and both are said to play the same theoretical roles in their respective sciences. However, an analysis of two seemingly disparate but in fact structurally related phenomena—‘niche construction’ (the case where organisms change their environment to make it fit (...) to their needs) and ‘adaptive preferences’ (the case where agents change their wants to make them fit to what the world has given them)—shows that one needs to be very careful about the postulation of this sort of fitness–utility connection. Specifically, I here use the analysis of these two phenomena to establish when connecting fitness and utility is and is not possible. (shrink)
