Computer-simulated scenarios have been part of psychological research on problem solving for more than 40 years. The shift in emphasis from simple toy problems to complex, more real-life oriented problems has been accompanied by discussions about the best ways to assess the process of solving complex problems. Psychometric issues such as reliable assessments and addressing correlations with other instruments have been in the foreground of these discussions and have left the content validity of complex problem solving in the background. In (...) this paper, we return the focus to content issues and address the important features that define complex problems. (shrink)

In this paper, I am going to offer a reconstruction of a challenge to intuition-based armchair philosophy that has been put forward by experimental philosophers of a restrictionist stripe, which I will call the 'master argument'. I will then discuss a number of popular objections to this argument and explain why they either fail to cast doubt on its first, empirical premise or do not go deep enough to make for a lasting rebuttal. Next, I will consider two more promising (...) objections, the grounding objection and the expertise objection, which aim at the second, epistemic premise of the argument. Against this background, I will then suggest what I call 'conservative restrictionism' as the most reasonable default reaction to the experimentalist challenge, which is a combination of the two views of local restrictionism and methodological conservativism.

Unlike other branches of science, the scientific products of synthetic chemistry are not only ideas but also new substances that change our material world, for the benefit or harm of living beings. This paper provides for the first time a systematical analysis of moral issues arising from chemical synthesis, based on concepts of responsibility and general morality. Topics include the questioning of moral neutrality of chemical synthesis as an end in itself, chemical weapons research, moral objections against improving material conditions (...) of life by chemical means, and freedom of research. The paper aims at providing both a sound basis for moral judgements of chemistry in a public discourse and a framework for chemists to reflect on the moral relevance of their activity. (shrink)

Along with the rapid worldwide advance of nanotechnology, debates on associated ethical issues have spread from local to international levels. However, unlike science and engineer- ing issues, international perceptions of ethical issues are very diverse. This paper provides an analysis of how sociocultural factors such as language, cultural heritage, economics and politics can affect how people perceive ethical issues of nanotechnology. By attempting to clarify the significance of sociocultural issues in ethical considerations my aim is to support the ongoing international (...) dialogue on nanotechnology. At the same time I pose the general question of ethical relativism in engineering ethics, that is to say whether or not different ethical views are irreconcilable on a fundamental level. (shrink)

An essential prerequisite for the development of a theory of consciousness is the clarification of the fundamental mechanisms underlying conscious processes. In this article I present an approach that sheds new light on these mechanisms. This approach builds on stochastic electrodynamics (SED), a promising theoretical framework that provides a deeper understanding of quantum systems and reveals the origin of quantum phenomena. I outline the most important concepts and findings of SED and interpret the neurophysiological body of evidence in the context (...) of these findings, indicating that the functioning of the brain rests upon exactly the same principles that are characteristic for quantum systems. On this basis, I construct a new hypothesis on the mechanisms behind conscious processes and discuss the new perspectives this hypothesis opens up for consciousness research. In particular, it offers the possibility of elucidating the relationship between brain and consciousness, of specifying the connection between consciousness and information, and of answering the question of what distinguishes conscious processes from unconscious processes.

In this paper, we propose a general constraint on theories of knowledge that we call ‘normalism’. Normalism is a view about the epistemic threshold that separates knowledge from mere true belief; its basic claim is that one knows only if one has at least a normal amount of epistemic support for one’s belief. We argue that something like normalism is required to do full justice to the normative role of knowledge in many key everyday practices, such as assertion, inquiry, and (...) testimony. The view of normality we employ to flesh out this claim is inspired by experimental work on the folk notion of normality, which suggests that folk judgments of what is ‘normal’ are based upon both statistical averages as well as normative ideals within the relevant target domain. Adopting this notion of normality to set the threshold for knowledge results in a view upon which knowledge is routinely available on an everyday basis without being a merely trivial achievement. We explore several interesting consequences of this view, including the implication that the threshold for knowing may change as, e.g., the ease of availability of information in an epistemic community changes over time. The result is a ‘shifty’ view of knowledge which nonetheless retains more stability than standard contextualist or pragmatic encroachment approaches. (shrink)

To approach the creation of artificial conscious systems systematically and to obtain certainty about the presence of phenomenal qualities (qualia) in these systems, we must first decipher the fundamental mechanism behind conscious processes. In achieving this goal, the conventional physicalist position exhibits obvious shortcomings in that it provides neither a plausible mechanism for the generation of qualia nor tangible demarcation criteria for conscious systems. Therefore, to remedy the deficiencies of the standard physicalist approach, a new theory for the understanding of (...) consciousness has been formulated. The aim of the paper is to present the cornerstones of this theory, to outline the conditions for conscious systems derived from the theory, and to address the implications of these conditions for the creation of robots that transcend the threshold of phenomenal awareness. In short, the theory is based on the proposition that the universe is permeated by a ubiquitous field of consciousness that can be equated with the zero-point field (ZPF) of quantum electrodynamics (QED). The ZPF, which is characterized by a spectrum of field modes, plays a crucial role in the edifice of modern physics. QED-based model calculations on cortical dynamics and empirical findings on the neural correlates of consciousness suggest that a physical system can only generate conscious states if it is capable of establishing resonant coupling to the ZPF, resulting in the amplification of selected field modes and the activation of the phenomenal qualities that are assumed to be associated with these modes. Thus, scientifically sound considerations support the conclusion that the crucial condition for generating conscious states lies in a system's capacity to tap into the phenomenal color palette inherent in the ZPF.

Zwischen Goethes Morphologiebegriff und Wittgensteins philosophischer Methode bestehen deutliche Parallelen, insofern man sie als Verfahren oder Anleitungen zur Erklärung und Darstellung natürlicher Phänomene (Goethe) bzw. der Begriffsbildung und -Verwendung (Wittgenstein) betrachtet. Den von Goethe als Entwicklungsmodelle und Vergleichshilfen gedeuteten Begriffen "Typus" und "Urbild" entsprechen Wittgensteins "Paradigmen" und "Muster"; beiden geht es um "übersichtliche" Darstellungen, und beide betonen die erklärungsrelevante Rolle der "Urphänomene".

Welcker was the first to develop the concept "Rechtsstaat" . Kant's concept of freedom, however, provides the background for Welcker's concept of the Rechtsstaat. This article investigates the question of how the concept "respect toward others" is related to the concepts "Rechtsstaat" and "right of freedom". According to Kant, "respect" is not a duty of law but rather a duty of virtue. Still we owe others fulfillment of this duty in a manner that is similar to the way we owe (...) them the fulfillment of a duty of law. Furthermore this duty of virtue corresponds to a moral right of others to respect. Although mutual respect among citizens is not constitutive of a Rechtsstaat, still it is in fact necessary for the survival of a Rechtsstaat. (shrink)

The article compares Kant's individual ethics and his philosophy of the state to the extent that it involves "morality with respect to the principles of public law". Kant rejects any form of first-order consequentialism as a standard of individual or state action. Nevertheless, he does indicate that the individual may hope to attain the summum bonum and that states may rely on attaining perpetual peace, as the highest political good. Accordingly, he introduces a second-order consequentialism into his moral philosophy. Understanding (...) the parallelism between the role of the summum bonum in Kant's individual ethics and the role of perpetual peace in his philosophy of the state clarifies the nature of second-order consequentialism. The requirement that the state be governed by the rule of law corresponds to the requirement in Kant's individual ethics that the individual follow the dictates of the categorical imperative without regard to utilitarian considerations, or that first-order consequentialism be rejected. The article argues that just as acting out of duty, regardless of any benefits to be gained thereby, is a necessary, and arguably sufficient, condition for attaining the summum bonum, so too is the rule of law a necessary, if not also sufficient, condition for the state in attaining perpetual peace. Der Beitrag zieht eine Parallele zwischen Kants Individualethik und seiner Staatsphilosophie, soweit "die Moral in Ansehung ihrer Grundsätze des öffentlichen Rechts" in Rede steht. Hier wie dort wendet sich Kant gegen jede Form eines "Konsequentialismus erster Ordnung". Mit seiner Hoffnung auf das individuelle höchste Gut einerseits und den ewigen Frieden auf Erden andererseits aber bringt er einen "Konsequentialismus zweiter Ordnung" ins Spiel. Die Parallele von Individualethik und Staatsphilosophie beleuchtet den Konsequentialismus zweiter Ordnung in der Staatsphilosophie mit ihrer Hoffnung auf den ewigen Frieden. Der nicht-konsequentialistischen Individualethik - "nicht-konsequentialistisch" im Sinne eines "Konsequentialismus erster Ordnung" - korrespondiert das Konzept des Rechtsstaats. Der Rechtsstaat erweist sich dabei als eine notwendige Bedingung für den ewigen Frieden. (shrink)

Der Beitrag kommt zuerst auf den Ursprung des Begriffs des Supererogatorischen zu sprechen. Er erörtert die Entwicklung des Gegensatzspaars praeceptum und consilium in der Antike und im Mittelalter. Der Begriff des Supererogatorischen und in seiner Folge der des consilium wird in der Reformation verworfen. An die Stelle der Unterscheidung von praeceptum und consilium tritt die Unterscheidung von vollkommenen und unvollkommenen Pflichten. Diese letztere Unterscheidung findet sich schon in der Antike. Nach der Reformation wird sie wiederbelebt. Die Kritik der Differenz von (...) vollkommenen und unvollkommenen Pflichten führt schließlich, über die Unterscheidung von verdienstlichen und schuldigen Pflichten, zu Kants Unterscheidung von juridischen und ethischen Gesetzen. In einer gewissen Weise läßt Kants Moralphilosophie Raum für supererogatorisches Verhalten. Eine verbreitete Kant-Interpretation bezieht den Begriff des Supererogatorischen auf das Ganze der ethischen Gesetze, und dann hat supererogatorisches Verhalten keinen Platz mehr. Für Kant bezieht sich der Begriff des Supererogatorischen dagegen auf das Ganze der juridischen Gesetze, mit Bezug auf die die Erfüllung der unvollkommenen Pflichten gegen andere supererogatorischen Charakter hat. Im Positivismus des 19. Jahrhunderts gehen die alten Unterscheidungen verloren. Die Neubelebung der Diskussion über den Begriff des Supererogatorischen im 20. Jahrhundert deutet auf eine Wende hin.

The Swamping Problem is one of the standard objections to reliabilism. If one assumes, as reliabilism does, that truth is the only non-instrumental epistemic value, then the worry is that the additional value of knowledge over true belief cannot be adequately explained, for reliability only has instrumental value relative to the non-instrumental value of truth. Goldman and Olsson reply to this objection that reliabilist knowledge raises the objective probability of future true beliefs and is thus more valuable than mere true (...) belief. I argue against their proposed solution to the Swamping Problem that the conditional probability of future true beliefs given knowledge is not clearly higher than given mere true belief. (shrink)

In this article, I present a novel approach to the scientific understanding of consciousness. It is based on the hypothesis that the full range of phenomenal qualities is built into the frequency spectrum of a ubiquitous background field and proceeds on the assumption that conscious systems employ a universal mechanism by means of which they are able to extract phenomenal nuances selectively from this field. I set forth that in the form of the zero-point field (ZPF) physics can offer a (...) promising candidate that is qualified for playing the dual role as both the carrier of energy and consciousness. The appropriate mechanism, which rests upon the principle of dynamical coupling of ZPF modes, is a unique feature of quantum systems, suggesting that the dividing line between conscious and non-conscious systems is defined by the differentiation between quantum systems and classical systems. The presence of this mechanism in the brain is supported by the neurophysiological body of evidence, leading to a consistent explanation of the dynamical properties of the neural correlates of consciousness. Building on these findings, I lay the foundations for the conceptually coherent integration of consciousness into the physical worldview, derive an indicator for the quantity of consciousness of a given system, and outline the further steps toward a theory of consciousness.

Man ist sie fast schon leid, die Rede vom „Chaos“, mit der wissenschaftspublizistisch versierte Forscher bemüht sind, sich ihren Anteil am hart umkämpften Markt der Forschungsmittel und -reputation zu sichern. Die inflationäre Verkündigung von „wissenschaftlichen Revolutionen“, „Paradigmenwechseln“ und „postmoderner Wissenschaft“ mag manchem Philosophen zwar insgeheim noch schmeicheln wegen der Gebrauchs- und Marktfähigkeit - und Autorität - philosophischer Termini. So recht zu glauben sind solche Botschaften jedoch selten. Aber welcher Philosoph wollte sich da ein sachgerechtes und kritisches Urteil erlauben, ob die (...) Inanspruchnahme philosophischer Begriffe an diversen aktuellen Forschungsfronten überhaupt angemesen ist? Wer könnte es andererseits besser, als jemand, der wie Theodor Leiber sowohl in Physik als auch in Philosophie promoviert ist und dessen überarbeitete Philosophiedisseration hier zur Diskussion steht?

Joachim Schulte’s introduction provides a distinctive and masterful account of the full range of Wittgenstein’s thought. It is concise but not compressed, substantive but not overloaded with developmental or technical detail, informed by the latest scholarship but not pedantic. Beginners will find it accessible and seasoned students of Wittgenstein will appreciate it for the illuminating overview it provides.

Empirical evidence indicates that conscious states, distinguished by the presence of phenomenal qualities, are closely linked to synchronized neural activity patterns whose dynamical characteristics can be attributed to self-organized criticality and phase transitions. These findings imply that insight into the mechanism by which the brain controls phase transitions will provide a deeper understanding of the fundamental mechanism by which the brain manages to transcend the threshold of consciousness. This article aims to show that the initiation of phase transitions and the (...) formation of synchronized activity patterns is due to the coupling of the brain to the zero-point field (ZPF), which plays a central role in quantum electrodynamics (QED). The ZPF stands for the presence of ubiquitous vacuum fluctuations of the electromagnetic field, represented by a spectrum of normal modes. With reference to QED-based model calculations, the details of the coupling mechanism are revealed, suggesting that critical brain dynamics is governed by the resonant interaction of the ZPF with the most abundant neurotransmitter glutamate. The pyramidal neurons in the cortical microcolumns turn out to be ideally suited to control this interaction. A direct consequence of resonant glutamate-ZPF coupling is the amplification of specific ZPF modes, which leads us to conclude that the ZPF is the key to the understanding of consciousness and that the distinctive feature of neurophysiological processes associated with conscious experience consists in modulating the ZPF. Postulating that the ZPF is an inherently sentient field and assuming that the spectrum of phenomenal qualities is represented by the normal modes of the ZPF, the significance of resonant glutamate-ZPF interaction for the formation of conscious states becomes apparent in that the amplification of specific ZPF modes is inextricably linked with the excitation of specific phenomenal qualities. This theory of consciousness, according to which phenomenal states arise through resonant amplification of zero-point modes, is given the acronym TRAZE. An experimental setup is specified that can be used to test a corollary of the theory, namely, the prediction that normally occurring conscious perceptions are absent under experimental conditions in which resonant glutamate-ZPF coupling is disrupted.

Kant famously argued that, from experience, we can only learn how something actually is, but not that it must be so. In this paper, I defend an improved version of Kant's argument for the existence of a priori knowledge, the Modal Argument , against recent objections by Casullo and Kitcher. For the sake of the argument, I concede Casullo's claim that we may know certain counterfactuals in an empirical way and thereby gain epistemic access to some nearby, nomologically possible worlds. (...) But I maintain that our beliefs about metaphysical necessities still cannot be justified empirically. Furthermore, I reject Casullo's deflationary thesis about the significance of such justification. Kitcher's most troublesome objection is that we can gain any modal justification whatsoever through testimony , i.e. in an experiential way. This can be countered by distinguishing between productive sources of justification, like perception, and merely reproductive sources, like testimony. Thus, some productive a priori source will always be needed somewhere. (shrink)

This paper investigates the development of nanotechnology from three different points of view: as a new technology, as social dynamics, and as an ideology. It argues that nanotechnology is not a new technology but a new social dynamics guided by programmatic ideas and situated at the interface between science and the public. Rather than being determined by social constructivism, the main argument is based on the poor scientific and technological identity of nanotechnology. Finally the paper concludes that nanotechnology is to (...) be considered an extension and increase of materials science and engineering, not only scientifically but in particular socially and ideologically, by pointing out common characteristics and differences.

Nanotechnology has from its very beginning been surrounded with an aura of novelty. For instance, on the 28 introductory pages of the report that prepared the US National Nanotechnology Initiative (NNI), Nanotechnology Research Directions (NSTC/IWGN 1999), we read 73 times the term “new”, 15 times “novel”, 7 times “innovation”, and 21 times “revolution”. The authors concede that one should distinguish between different nanotechnologies, because “Many existing technologies do already depend on nanoscale processes. Photography and catalysis are two examples of ‘old’ (...) nanotechnologies” (ibid, p. xxvi). One might conclude here that, if all the existing nanotechnologies are “old” nanotechnologies, “new” nanotechnologies do not yet exists but are only promises of the future. However, without further explanation and distinction between presence and future, they suggest that most nanotechnologies are or will be new. Furthermore, they claim that nanotechnology (in singular) is a generator of further new technologies, since “Nanotechnology will give birth to new fields that at present are only visions of leading researchers” (ibid., p. xviii). Whenever science managers speak of nanotechnology (in singular), sophisticated distinctions seem to give way to plain claims about the present and future novelty of nanotechnology. As the NNI director Mihail Roco wrote in a 2001 report, “A revolution is occurring in science and technology […] Nanotechnology will fundamentally transform science, technology, and society. In 10 to 20 years, a significant proportion of industrial production, healthcare practice, and environmental management will be changed by the new technology.” (Roco & Bainbridge, pp. 1, 19) When they put on their hats as science managers, scientists rarely reject but mostly support such novelty claim, as did for instance the chemists George Whitesides and Paul Alivisatos in the earlier report: “Nanostructures are the entry into a new realm in physical and biological science.” (NSTC/IWGN 1999, p..

This book does not only attempt to clarify concepts used in the context of dialectical reasoning but also develops an epistemological theory by answering the question: What does it mean to possess a language? The epistemological theory then is used to ground the basis of social science in the logic of our common-sense language. This logic is viewed as more comprehensive than traditional formalized logic, which is viewed as only one though an important aspect of the more general and basic (...) logic of our common-sense language.

A surveyable representation produces precisely that kind of understanding which consists in ‘seeing connections’. Most of the sentences that go to make up the remarks of Philosophical Investigations can be found in manuscript passages written in June 1931. On 20 November of the same year Wittgenstein writes a letter in reply to a request from Schlick and complains, not only about his own sluggishness, but also about Waismann's inclination to misrepresent his own ideas. In fact, Spengler says a number of (...) things about Weltanschauungen, and it may well be that several passages could be seen to fill the bill. In a way, nonfactual intermediate links, which begins by mentioning 'hypothetical' connecting links and says that they are merely supposed to draw attention to connections between facts. But an hypothetical connecting link should in this case do nothing but direct the attention to the similarity, the relatedness, of the facts. (shrink)

We are used to considering engineering ethics largely a critical enterprise. By pointing out ethical issues and by raising concerns about a technology, ethicists usually criticise rather than promote the technology in question. Of course, from a utilitarianist perspective, an ethicist might come to the conclusion that a certain technology is better than another one or than doing without. However, such conclusions are rare in philosophy and would not be considered uncritical promotion. In this essay I argue that engineering ethics, (...) almost unavoidably, turns into the promotion and popularisation of a technology if that technology does not exist yet but is considered to be emerging in the near future. In other words, ethics of emerging technologies is not only prone to but almost destined to play a propaganda role in the public sphere. As engineering ethics moves from established to emerging technologies ethicists need to be aware that they become useful instruments in the struggle for public attention and funding. (shrink)
