We present the idea of searching for X-rays as a signature of the mechanism inducing the spontaneous collapse of the wave function. Such a signal is predicted by the continuous spontaneous localization theories, which are solving the “measurement problem” by modifying the Schrödinger equation. We will show some encouraging preliminary results and discuss future plans and strategy.

The present study investigated whether individual differences between psychologists in thinking styles are associated with accuracy in diagnostic classification. We asked novice and experienced clinicians to classify two clinical cases of clients with two co-occurring psychological disorders. No significant difference in diagnostic accuracy was found between the two groups, but when combining the data from novices and experienced psychologists accuracy was found to be negatively associated with certain decision making strategies and with a higher self-assessed ability and preference for a (...) rational thinking style. Our results underscore the idea that it might be fruitful to look for explanations of differences in the accuracy of diagnostic judgments in individual differences between psychologists (such as in thinking styles or decision making strategies used), rather than in experience level.

Science, engineering and technology are still male-dominated fields, and thus all over Europe much effort is expended on activities which, it is hoped, will lead to a sustainable gender balance. Scholarly work has frequently focused on the topic of how to motivate women to enter SET fields or to choose a corresponding education. In contrast to this one-sided approach, recent scholarly contributions have begun to emphasize the vital role of gendered structures and indirect exclusion mechanisms of technological institutions and their (...) professional self-understandings which discourage women from entering or staying in SET organizations. In particular, taken-for-granted knowledge as a mechanism for maintaining specific norms and values is considered a primary hindrance towards more inclusive and less oppressive organizational cultures. Since this taken-for-granted knowledge is often implicit, a primary goal of research can be said to make the invisible visible. Thus this article presents selected empirical results of a research project which makes use of an investigative tool called mind-scripting. Here the aim is to identify the main barriers, in terms of unquestioned taken-for granted knowledge, currently hindering an open and critical review of gendered structures and gender codes in the SET field, or in organizations in general, particularly with respect to professional norms.

In this article, I analyze the relation between ontology and practical philosophy in Cicero’s work and the role Hellenistic philosophy plays within the work of Giorgio Agamben. I discuss the relation between life and ontology, between philosophy as a guide to living and philosophy as the study of being. Unlike philosophers who treat Hellenistic philosophy as a form of therapy, I show how Agamben interprets Hellenistic philosophy as oppressive by turning the theory of being into an injunction of having-to-be. For (...) Agamben, every philosophy implies a certain form of life, and it is thus impossible to distinguish between ontology and living. The aim of philosophy, therefore, is not to be therapeutic but rather to develop an ontology that will allow for humanity to live without oppression. Through a detailed reading of Cicero’s concept of “nature,” I develop the reading and critique of Cicero suggested by Agamben.Cet article analyse la relation entre l’ontologie et la philosophie pratique dans l’oeuvre de Cicéron et le rôle joué par la philosophie hellénistique dans l’oeuvre de Giorgio Agamben. Il discute la relation entre la vie et l’ontologie, entre la philosophie comme guide de savoir-vivre et la philosophie comme étude de l’être. Contrairement aux philosophes qui traitent la philosophie hellénistique comme une forme de thérapie, je montre que Agamben interprète la philosophie hellénistique comme essentielle-ment oppressive en transformant la théorie de l'être en une injonction normative de devoir-être. Pour Agamben, toute philosophie implique une certaine forme de vie, rendant alors la distinction entre l’ontologie et la vie impossible. Ainsi, le but de la philosophie n'est pas d’être thérapeutique mais plutôt de développer une ontologie qui permettra à l’humanité de vivre sans oppression. Par une lecture du concept de la « nature » de Cicéron, je développe l’interprétation et la critique de Cicéron proposé par Agamben. (shrink)

We present an experimental test of the validity of the Pauli Exclusion Principle for electrons based on the concept put forward a few years ago by Ramberg and Snow. In this experiment we perform a very accurate search of X-rays from the Pauli-forbidden atomic transitions of electrons in the already filled 1S shells of copper atoms. Although the experiment has a simple structure, it poses deep conceptual and interpretational problems. Here we describe the experimental method and recent experimental results, which (...) we interpret as an upper limit for the probability to violate the Pauli Exclusion Principle. We present also future plans to upgrade the experimental apparatus using Silicon Drift Detectors. (shrink)

Intellectual historians have tended to focus on the most radical intellectuals of the counter-revolution such as Joseph de Maistre and Louis de Bonald, but the counter-revolution was an intellectually composite movement with many intellectual currents and ideas. In this article, I shed light on the composite character of the counter-revolution by focusing on one of its most moderate members, the comte de Montlosier. The article presents contextualised analysis of Montlosier’s conception of moderation, his theory of politics, his critique of fellow (...) counter-revolutionaries, and his ideas for a new aristocratic order build on public opinion and separation of powers. I argue that Montlosier’s moderate politics reflected a moderate enlightenment approach to politics, which was neither wholly rationalist nor wholly traditionalist. Rather, it was an attempt to find a middle ground between the two integrating a conservative view of history with a sociological approach to power and politics. I furthermore argue that even if Montlosier was unsuccessful in his endeavours to moderate the counter-revolution, he nonetheless provided a moderate response to it that would become integral to nineteenth-century conservative and liberal ideas.

This article investigates the theory of an imperative mandate as presented in the radical French revolutionary Jean-François Varlet’s text Project for a Special and Imperative Mandate from 1792. This text is taken as, and shown to be, representative for a widespread understanding of radical democracy during the French Revolution in which deputies were not understood as ‘representatives’ but as ‘mandataries’ who were legally bound to follow the instructions of their commettants. As an essential part of this radical conception of democracy, (...) social movements were to be constantly mobilized and able to supervise the political system. This entails a shift in the balance of power from the state to the social movements, and as such it expresses a different conception of democracy than that of liberal democracy with its rule of law and state monopoly of violence.

The Italian philosopher Giorgio Agamben’s conception and critique of sovereignty has won him wide and well-deserved acclamation. In this article, however, it is argued that Agamben’s conception of sovereignty is somewhat misplaced, and, as a consequence, his positive political project of developing a ‘destituent power’ is highly deficient in terms of construing a popular and viable political alternative. The critique of Agamben is developed through a close reading of Aristotle’s Politics and his notion of kurion. It is argued that Agamben’s (...) flawed conception of sovereignty reemerges symptomatically in his extremely problematic reading of Aristotle’s Politics, and that a viable political alternative to both Agamben’s own project and the conception of politics that he criticizes can be developed through an alternative and closer reading of Aristotle.

Two experiments were conducted to show that the IF … THEN … rules used in the different versions of Wason 's selection task are not psychologically—though they are logically—equivalent. Some of these rules are considered by the participants as strict logical conditionals, whereas others are interpreted as expressing a biconditional relationship. A deductive task was used jointly with the selection task to show that the original abstract rule is quite ambiguous in this respect, contrary to deontic rules: the typical “error” (...) made by most people may indeed be explained by the fact that they consider the abstract rule as a biconditional. Thus, there is no proper error or bias in the selection task as it is still argued, but a differential interpretation of the rule. The need for taking into account a pragmatic component in the process of reasoning is illustrated by the experiments. (shrink)

This article contributes to governmentality studies and state theory by discussing how to understand the centrality and importance of the state from a governmentality perspective. It uses Giorgio Agamben’s critique of Michel Foucault’s governmentality approach as a point of departure for re-investigating Foucault as a thinker of the state. It focuses on Foucault’s notion of the state as a process of ‘statification’ which emphasizes the state as something constantly produced and reproduced by processes and practices of government, administration and acclamation. (...) As a result of this, the state appears as a given entity which is necessary for the multiplicity of governmental technologies and practices in modern society to function. Only by reference to the state can governmental practices be effective and legitimized. Finally, the article conceptualizes the centrality of the state through Foucault’s notions of the state as a ‘practico-reflexive prism’ and a ‘principle of intelligibility’. (shrink)

In this text, Giorgio Agamben argues that the concept of democracy attests to a political, ontological amphibology: on the one side, democracy describes a constitution of a political order ; on the other side, democracy is a certain form of administration. It is argued that this amphibology can be located in the political theories of Aristotle and Jean-Jacques Rousseau who have been instrumental in forming our present conception of politics. Consequently, we misunderstand the fundamental nature of politics, and any hopes (...) of genuine political life must therefore break with this tradition of Western political philosophy. (shrink)

In the modern debate in metaethics and moral psychology, moral rationalism is often presented as a view that cannot account for the intimate relation between moral behaviour on one hand and feelings, emotions, or desires on the other. Although there is no lack of references to the classic rationalists of the 18th century in the relevant discussions, the works of these writers are rarely ever examined detail. Yet, as the debate in Kant scholarship between “intellectualists” and “affectivists” impressively shows, a (...) more thorough analysis of what the classic rationalists actually have to say about moral motivation is suited to cast serious doubts on the idea that moral rationalism must crucially neglect the affective–conative side of human psychology. The aim of this paper is to analyse the conceptions of moral motivation that were embraced by Kant's rationalist predecessors—Clarke, Wolff, Burnet, Balguy, and Price—which have not attracted a similar amount of attention by specialists so far. The claim I will defend is that none of those early rationalists actually embraces the motivational thesis that is often taken to be characteristic of moral rationalism, a thesis I shall refer to as strong rationalism about (moral) motivation.

The aim of this paper is to critically review the game-theoretic discussion of Hobbes and to develop a game-theoretic interpretation that gives due attention both to Hobbes's distinction between “moderates” and “dominators” and to what actually initiates conflict in the state of nature, namely, the competition for vital goods. As can be shown, Hobbes's state of nature contains differently structured situations of choice, the game-theoretic representation of which requires the prisoner's dilemma and the assurance game and the so-called assurance dilemma. (...) However, the “state of war” ultimately emerges from situations that cannot be described by any of these games because they represent zero-sum games in which the outcome of mutual cooperation does not exist.

In a letter of 1932, Karl Popper described _Die beiden Grundprobleme der Erkenntnistheorie – The Two Fundamental Problems of the Theory of Knowledge_ – as ‘…a child of crises, above all of …the crisis of physics.’ Finally available in English, it is a major contribution to the philosophy of science, epistemology and twentieth century philosophy generally. The two fundamental problems of knowledge that lie at the centre of the book are the problem of induction, that although we are able to (...) observe only a limited number of particular events, science nevertheless advances unrestricted universal statements; and the problem of demarcation, which asks for a separating line between empirical science and non-science. Popper seeks to solve these two basic problems with his celebrated theory of falsifiability, arguing that the inferences made in science are not inductive but deductive; science does not start with observations and proceed to generalise them but with problems, which it attacks with bold conjectures. _The Two Fundamental Problems of the Theory of Knowledge_ is essential reading for anyone interested in Karl Popper, in the history and philosophy of science, and in the methods and theories of science itself.

Much in contemporary metaethics revolves around the two positions known as ‘motivational internalism’ and the ‘Humean theory of motivation’. The importance of these positions is mostly due to their role in what is considered to be the most powerful argument for metaethical non-cognitivism: the so-called ‘motivation argument’. In my paper, I want to argue that widely accepted renditions of the MA, such as the rendition recently forwarded by Russ Shafer-Landau, are flawed in two senses. First, they fail to sufficiently distinguish (...) between conceptual claims and empirical psychological claims, thereby somewhat obscuring the status of the argument and its conclusion. Secondly, they start from definitions of motivational internalism that are, in crucial respects, too strong. Motivational internalism is usually formulated as the claim that moral judgements necessarily motivate; as I want to argue, however, the claim that moral judgements potentially motivate is all the motivational internalism a noncognitivist defender of the MA is ever going to need.

The paper critically discusses the deontological interpretation of Hobbesian contractual obligation which has been advocated by commentators such as Brian Barry, D. D. Raphael and Bernd Ludwig. According to this interpretation, the obligation to comply with contracts and covenants is fundamentally different from the obligation to observe the laws of nature. While the latter is taken to be a prudential obligation that is logically dependent upon the individual aim of self-preservation, the former is viewed as an absolute or unconditional moral (...) obligation that solely follows from the fact that the individual has bound himself to the performance or omission of certain actions. As can be shown, the deontological interpretation suffers from inherent problems and does not provide an appropriate interpretation of the Hobbesian texts. In particular, it can be demonstrated that the attempt to use Hobbes's concept of 'freedom as deliberation' in order to explain how obligations arise from contractual agreements faces serious difficulties.

Following the work of Peter Schmitt-Egner, this article lays out a value-form theoretical approach to racism. During the debates within German Marxism on the reconstruction of the critique of political economy (Neue Marx-Lektüre), Schmitt-Egner developed a theory in the 1970s that tries to explain racism with reference to Marx’s analysis of the commodity form and circulation. Thereby he developed a highly original theoretical derivation of racism as an ideological reification of the debased position of colonised labour power in comparison with (...) that of metropolitan workers. The bourgeois ideals of freedom and equality, constituted through commodity circulation, according to Schmitt-Egner, are modified by the nature of the colonial production process and thus negated in the case of the racialised worker. Even if his theory, as I am going to show, has some serious flaws, it helps to make sense of past and current patterns of racist inferiorisation. (shrink)

This paper discusses the juridical interpretation of Hobbes’s state of nature argument, which has been defended by commentators such as Georg Geismann, Dieter Hüning or Peter Schröder. According to the juridical interpretation, the primary reason why the Hobbesian state of nature needs to be abandoned is not that everybody’s self-preservation is constantly threatened. It is that, due to the universal right to all things, the jural order of the state of nature includes some kind of logical contradiction. The purpose of (...) the paper is to show that the juridical interpretation does not do justice to Hobbes’s actual argument and that it starts from a false presupposition: being a Hohfeldian ‘liberty-right’, the right to all things can consistently be granted to all individuals at the same time.

Die Theorie des Thomas Hobbes hat in der Vergangenheit stark abweichende Deutungen erfahren und Anlass zu zahlreichen lang anhaltenden Debatten geliefert. Die Diskussion hat jedoch allgemein darunter gelitten, dass Hobbes' Schriften von der berwiegenden Anzahl der Interpreten wie ein in sich zusammenh ngender Textkorpus behandelt und die Unterschiede zwischen den verschiedenen Werken nicht hinreichend gew rdigt worden sind. In besonderem Ma e trifft das auf die Naturzustandstheorie zu, die im Zentrum der Hobbes'schen Argumentation steht und in gro em Ma f (...) r die Entstehung und das Fortdauern der genannten Debatten verantwortlich zu machen ist. Ziel der vorliegenden Arbeit ist es, die verschiedenen Fassungen der Naturzustandstheorie endlich einer umfassenden vergleichenden Analyse zu unterziehen, und zwar unter konsequenter Einbeziehung des gerade in der deutschen Hobbes-Forschung kaum beachteten Textes des lateinischen Leviathan. Wie sich eindrucksvoll zeigt, vermag der eingehende Vergleich der Schriften nicht nur einen wichtigen Beitrag zum Verst ndnis von Hobbes' philosophischer Entwicklung und zur Bestimmung des Stellenwertes des lateinischen Leviathan zu leisten. Er liefert auch einen wichtigen Beitrag zur kritischen Bewertung der vorliegenden Hobbes-Interpretationen und zur Aufl sung einiger zentraler Debatten. (shrink)

The eighteenth century debate between moral rationalists and moral sentimentalists has seen a striking renaissance in the past decades, not least because of research into the nature of moral judgement conducted by empirical scientists such as social and developmental psychologists and neuroscientists. A claim that is often made in the current discussion is that the evidence made available by such empirical investigations refutes rationalist conceptions of moral judgement and vindicates the views of Hume or other moral sentimentalists. For example, Jesse (...) Prinz and Hanno Sauer have recently argued that the available data demonstrates that emotions are both necessary and sufficient for moral judgement and that the best or the only way to make sense of these findings is to conclude that moral judgements are constituted by emotions. The aim of this paper is to thoroughly examine this argument and the underlying empirical evidence and to show that there is currently no compelling evidence for the truth of either the necessity or the sufficiency thesis and that, even if both theses were true, they would fail to provide a sound basis for a plausible sentimentalist constitution claim.

: The aim of this paper is to analyse the status of Locke’s state of nature and to examine whether the distinction between different theoretical perspectives can help to resolve the apparent contradictions between Locke’s ‘peaceful’ and his ‘warlike’ description of the natural state, a claim that has been made by commentators such as R. Ashcraft, J. Dunn and H. Aarsleff. Though, it is argued, distinguishing different state of nature accounts in Locke is essential for an appropriate understanding of Locke’s (...) argument, the attempt to thereby free Locke of the charge of inconsistency fails. The reason is that the ‘peaceful’ and the ‘warlike’ description are equally part of Locke’s anthropological analysis. They can, therefore, not be reconciled by distinguishing between a ‘moral’ account of the state of nature on the one hand and an empirical account on the other. (shrink)

One important trend in the debate over expressivism and cognitivism is the emergence of ‘hybrid’ or ‘ecumenical’ theories. According to such theories, moral sentences express both beliefs, as cognitivism has it, and desire-like states, as expressivism has it. One may wonder, though, whether the hybrid move is as novel as its advocates seem to take it to be—or whether it simply leads us back to the conceptions of early expressivists, such as Charles Stevenson or Richard Hare. Michael Ridge has recently (...) argued that we ought not to see Hare as a hybrid expressivist because Hare’s approach allows for moral sentences that do not express any descriptive beliefs at all. Yet, Ridge’s reading has been challenged by John Eriksson, who even goes as far as to claim that modern hybrid expressivists should follow in Hare’s footsteps because it is Hare’s framework that actually provides a solution to the so-called ‘Frege-Geach problem’. In the present paper, I first want to show that we can defend Eriksson’s reading with regard to the official version of Hare’s theory. I will, secondly, argue that, in line with what we may take to be Ridge’s critical perspective on Hare, this official version faces serious difficulties, resulting from the possibility of unknown speaker standards. Thirdly, I will demonstrate that a modern reconstruction of Hare in terms of what I will refer to as ‘de dicto beliefs’, though in principle possible, will not allow us to solve the ‘Frege-Geach problem’.

The General Theory defended Keynes's long‐held belief that capitalism could not achieve full employment without government help. The effects of wage rigidity were well known; Keynes tried to show that even price flexibility—contrary to Say's Law—could not reduce unemployment. Keynes did so by hobbling his decisionmakers with “psychological laws,”; like the consumption function, that linked nominal prices together. These produced a rigidity of relative prices that justified government intervention. Keynes's followers seem to have rejected his psychological theories, emphasizing instead nominal (...) rigidities or uncertainty, either of which is consistent with “classical”; thinking and Say's Law.

Recent research has shown that psychological risk factors play an important role in the pathogenesis of cardiovascular diseases. The so-called coronary prone behaviour pattern predominates, an important part of which is the Type A behaviour pattern. This is characterized by a marked ambition, a constant feeling of being under pressure, due to latent aggression and to a striving to dominate. For cerebrovascular diseases the so-called pressured pattern as a risk factor has been found to be typical which is comparable to (...) the Type A behaviour. Psychological risk factors and their components are not equally important for different vascular diseases. Besides the explanation of the question as to how far psychological processes really are involved in the development of vascular diseases, the research on psychological risk factors serves as a foundation for psychosomatic theories.

Expressivism has been dominating much of the metaethical debate of the past three decades. The aim of this book is to address a number of questions that have been neglected in the previous discussion.These primarily concern the psychological commitments and the methodological status of expressivism as well as important differences and similarities between the approaches of the 'classic' expressivists Ayer, Stevenson, Hare, Blackburn und Gibbard.
