A historical overview is given of the contributions of Hendrik Antoon Lorentz in quantum theory. Although especially his early work is valuable, the main importance of Lorentz’s work lies in the conceptual clarifications he provided and in his critique of the foundations of quantum theory.

This book pieces together the jigsaw puzzle of Einstein's journey to discovering the special theory of relativity. Between 1902 and 1905, Einstein sat in the Patent Office and may have made calculations on old pieces of paper that were once patent drafts. One can imagine Einstein trying to hide from his boss, writing notes on small sheets of paper, and, according to reports, seeing to it that the small sheets of paper on which he was writing would vanish into his (...) desk-drawer as soon as he heard footsteps approaching his door. He probably discarded many pieces of papers and calculations and flung them in the waste paper basket in the Patent Office. The end result was that Einstein published nothing regarding the special theory of relativity prior to 1905. For many years before 1905, he had been intensely concerned with the topic; in fact, he was busily working on the problem for seven or eight years prior to 1905. Unfortunately, there are no surviving notebooks and manuscripts, no notes and papers or other primary sources from this critical period to provide any information about the crucial steps that led Einstein to his great discovery. In May 1905, Henri Poincare sent three letters to Hendrik Lorentz at the same time that Einstein wrote his famous May 1905 letter to Conrad Habicht, promising him four works, of which the fourth one, Relativity, was a rough draft at that point. In the May 1905 letters to Lorentz, Poincare presented the basic equations of his 1905 "Dynamics of the Electron", meaning that, at this point, Poincare and Einstein both had drafts of papers relating to the principle of relativity. The book discusses Einstein's and Poincare's creativity and the process by which their ideas developed. The book also explores the misunderstandings and paradoxes apparent in the theory of relativity, and unravels the subtleties and creativity of Einstein. (shrink)

I show that Albert Einstein’s distinction between principle and constructive theories was predated by Hendrik A. Lorentz’s equivalent distinction between mechanism- and principle-theories. I further argue that Lorentz’s views toward realism similarly prefigure what Arthur Fine identified as Einstein’s ‘‘motivational realism.’’ r 2005 Published by Elsevier Ltd.

The relationship between Albert Einstein’s special theory of relativity and Hendrik A. Lorentz’s ether theory is best understood in terms of competing interpretations of Lorentz invariance. In the 1890s, Lorentz proved and exploited the Lorentz invariance of Maxwell’s equations, the laws governing electromagnetic fields in the ether, with what he called the theorem of corresponding states. To account for the negative results of attempts to detect the earth’s motion through the ether, Lorentz, in effect, (...) had to assume that the laws governing the matter interacting with the fields are Lorentz invariant as well. This additional assumption can be seen as a generalization of the well-known contraction hypothesis. In Lorentz’s theory, it remained an unexplained coincidence that both the laws governing fields and the laws governing matter should be Lorentz invariant. In special relativity, by contrast, the Lorentz invariance of all physical laws directly reflects the Minkowski space-time structure posited by the theory. One can use this observation to produce a common-cause argument to show that the relativistic interpretation of Lorentz invariance is preferable to Lorentz’s interpretation. (shrink)

In this paper I argue that the case of Einstein׳s special relativity vs. Hendrik Lorentz׳s ether theory can be decided in terms of empirical evidence, in spite of the predictive equivalence between the theories. In the historical and philosophical literature this case has been typically addressed focusing on non-empirical features. I claim that non-empirical features are not enough to provide a fully objective and uniquely determined choice in instances of empirical equivalence. However, I argue that if we consider (...) arguments proposed by Richard Boyd, and by Larry Laudan and Jarret Leplin, a choice based on non-entailed empirical evidence favoring Einstein׳s theory can be made.

A inicios del siglo XX, Albert Einstein y Hendrik Lorentz produjeron explicaciones diferentes acerca de los mismos fenómenos. Sin embargo, rápidamente se produjo un consenso, en favor de Einstein, que ha sido difícil de comprender para historiadores y filósofos de la ciencia. La literatura reciente explica ese éxito señalando conflictos entre algunas ideas de Lorentz y la temprana física cuántica. Sin negar que esos factores pudieron contribuir en la aceptación de la relatividad especial, propongo una explicación complementaria (...) en la que atribuyo el éxito de Einstein al uso de la estabilidad de la medición de la velocidad de la luz.

The revised edition contains a new chapter which provides an elegant description of the semantics. The various classes of lambda calculus models are described in a uniform manner. Some didactical improvements have been made to this edition. An example of a simple model is given and then the general theory (of categorical models) is developed. Indications are given of those parts of the book which can be used to form a coherent course.

In this paper, we first classify different types of second opinions and evaluate the ethical and epistemological implications of providing those in a clinical context. Second, we discuss the issue of how artificial intelligent could replace the human cognitive labour of providing such second opinion and find that several AI reach the levels of accuracy and efficiency needed to clarify their use an urgent ethical issue. Third, we outline the normative conditions of how AI may be used as second opinion (...) in clinical processes, weighing the benefits of its efficiency against concerns of responsibility attribution. Fourth, we provide a ‘rule of disagreement’ that fulfils these conditions while retaining some of the benefits of expanding the use of AI-based decision support systems in clinical contexts. This is because the rule of disagreement proposes to use AI as much as possible, but retain the ability to use human second opinions to resolve disagreements between AI and physician-in-charge. Fifth, we discuss some counterarguments. (shrink)

Conflicts in Interpretation applies novel methods of constraint interaction, derived from connectionist theories and implemented in linguistics within the framework of Optimality Theory, to core semantic and pragmatic issues such as polysemy, negation, (in) definiteness, focus, anaphora, and rhetorical structure. It explores the hypothesis that a natural language grammar is a set of potentially conflicting constraints on forms and meanings. Moreover, it hypothesizes that competent language users not only optimize from an input form to the optimal output meaning for this (...) form, or vice versa, but also consider the opposite direction of optimization, thus taking into account the speaker as a hearer and taking into account the hearer as a speaker. The book aims to show that such a bidirectional constraint-based grammar sheds new light on the relation between form and meaning, within a sentence as well as across sentence boundaries, within a single language as well as across languages, and within competent adult language users as well as during language development. An important dimension of the book is the structured investigation of issues at the interface of semantics with syntax and pragmatics, such as the effects of distinguishing between speaker's perspective and hearer's perspective in comprehension and production, stable and instable patterns of form and meaning across languages, and the development of a coherent pattern of form and meaning in children. Conflicts in Interpretation will be of interest to any researcher or advanced student in linguistics, cognitive science, language typology, or psycholinguistics who is interested in the capacity of our human mind to map meaning onto form, and form onto meaning.

Descartes' works were not allowed to be read at Leiden University, even his name could not be pronounced. Read the compelling story about how his pupil Johannes de Raey has had the opportunity to preach Descartes fully in philosophy, but also in medicine, in a hostile anti-Cartesian climate during 20 years (1647-1668). This book is not only meant for philosophers and medical historians, but for all who want to take a look at the extensive menu of Cartesian cuisine. The 17th-century (...) philosopher René Descartes turned established science upside down by doubting all certainties. His critical mind rejected statements that could not be proven by the Ratio. The Ratio was the metaphor for the roots, the physics for the trunk and the medicine for the branches and leaves of the Cartesian tree. This premise was directly opposed to the established aristotelian theory in which observation formed the basis of knowledge. De Raey, who once called Descartes his best student, synthesized a hybrid model of the old Aristotelian and the new Cartesian concept. From 1658 to 1662 he gave private lessons in medicine at Leiden University and tried to use his model as a basis for explaining human physiology. Until now, nothing was known about the content of these lectures. The author recently found a dispute. It is a new dish on the Cartesian menu. (shrink)

Hendrik Lorenz presents a comprehensive study of Plato's and Aristotle's conceptions of non-rational desire. They see this as something that humans share with animals, and which aims primarily at the pleasures of food, drink, and sex. Lorenz explores the cognitive resources that both philosophers make available for the explanation of such desires, and what they take rationality to add to the motivational structure of human beings. In doing so, he finds conceptions of the mind that are coherent and deeply (...) integrated with both philosophers' views about such topics as the relation between body and soul, or the nature of the virtues.

This article seeks to demonstrate that in his recent reading of the role of religion in the postsecular public realm, Habermas overlooks a most fundamental dimension of religion: its power to symbolically institute communities. For his part, Gauchet starts from a vision of religion in which this fundamental dimension is central. In his evaluation of the role of religion in postsecular society, he therefore arrives at results which are very different from those of Habermas. However, I believe that Gauchet too (...) underestimates the extent to which religion’s power of symbolic community institution has remained intact within modern, postsecular society. In support of this position, I show how relatively heterogeneous phenomena within Western societies, such as the renewed importance of religion in the public realm, the revival of certain forms of nationalism and the associated demand for recognition of group rights and hence for forms of legal pluralism, may prefigure a new transformation of the public realm.

This paper explores the role and resolution of disagreements between physicians and their diagnostic AI-based decision support systems. With an ever-growing number of applications for these independently operating diagnostic tools, it becomes less and less clear what a physician ought to do in case their diagnosis is in faultless conflict with the results of the DSS. The consequences of such uncertainty can ultimately lead to effects detrimental to the intended purpose of such machines, e.g. by shifting the burden of proof (...) towards a physician. Thus, we require normative clarity for integrating these machines without affecting established, trusted, and relied upon workflows. In reconstructing different causes of conflicts between physicians and their AI-based tools—inspired by the approach of “meaningful human control” over autonomous systems and the challenges to resolve them—we will delineate normative conditions for “meaningful disagreements”. These incorporate the potential of DSS to take on more tasks and outline how the moral responsibility of a physician can be preserved in an increasingly automated clinical work environment. (shrink)

Our self-image is constructed in the interplay between man and culture. Religious traditions play a key role in this interplay; myths create meaning to the individual and to society at large. Sacred narratives provide man with patterns of behavior, how life should be lived. The other side of the picture is that identity and integrity may lead to intolerance, a dividing line between them and us: the most serious obstacle to peace and intercultural understanding. Religions can reinforce strong feelings of (...) humiliation, of being a victim. This, in turn, may lead to the splitting of humanity into good and evil; one group demonizes the other. This coupled with an idealized, wrathful and punitive deity or leader may lead to violence, and violence is sanctified. Religion may encourage feelings of humiliation, but it can also deliver an antidote. There are theological resources that can counter terror and violence. A merciful and compassionate God can replace a wrathful and punitive deity. A stage of faith known as gerotranscendence is characterised by “an increasing feeling of belonging to the universe”. Representatives of ‘glocal’ spirituality reject claims of exclusivity. A glocal perspective is crucial. What we need today is that a greater number of spiritual leaders stand up and insist on values that touch upon the sanctity of life. (shrink)

The author suggests a new model for interpretation of mystical experience, based on a fruitful combination of cognitive psychology and depth psychology. Offering a rather wide definition of mystical experience, the author then turns to two basic assumptions—a general systems approach and an organismic-holistic view of development. Hans Loewald's analysis of primary process cognition is combined with a multi-dimensional model of cognitive activity called "Interacting Cognitive Subsystems" , presented by John D. Teasdale and Philip J. Barnard. These two complementary theoretical (...) perspectives are applied to the analysis of both historical and contemporary examples of mystical experience, understood as a result of a dialectical interplay between these different coding systems, or the marriage between Ego and Id.

Inleiding tot de Duitse filosoof (1724-1804).

Aristotle takes practical wisdom and arts or crafts to be forms of knowledge which, we argue, can usefully be thought of as ‘empiricist’. This empiricism has two key features: knowledge does not rest on grasping unobservable natures or essences; and knowledge does not rest on grasping logical relations that hold among propositions. Instead, knowledge rests on observation, memory, experience and everyday uses of reason. While Aristotle’s conception of theoretical knowledge does require grasping unobservable essences and logical relations that hold among (...) suitable propositions, his conception of practical and productive knowledge avoids such requirements and is consistent with empiricism.

This article sets up a dialogue between Lefort’s view on the relationship between state and modern society and Foucault’s thesis of a governmental turn in the modern power regime. Whereas Lefort’s political ontology leaves room for divergent agencies from which the symbolic institution of the social may unfold, his preoccupation with democracy leads him to link the symbolic institution of modern society inseparably with the functioning of the modern state. By contrast, Foucault’s history of governmentality documents a shift in the (...) regime of the symbolic institution of modern society. Where that institution hitherto relied on the state, today, a symbiosis of state and neoliberal governmentality seems to take over. Foucault’s highlighting of the neoliberal conception of a generalized market may thus undermine the ontological role Lefort formerly ascribed to the state. In conclusion it is suggested that this shift in power regime is by and large responsible for the readjustment of the instituting representations of contemporary society, the de-politicization of political and social relations, and the erosion of democracy.

With special attention being paid to recent developments in Artificial Intelligence and the Law, specifically related to evidentiary reasoning, this book ...

The general claim advanced in this article is that Foucault’s genealogy of the modern state traces two ideal-typically different power arrangements at the origin of the modern state, roughly referred to as ‘sovereign power’ and ‘governmentality’. They are ideal-typically different in that they operate according to a different logic, including different ends, means and modi operandi. The more specific claim, then, is that due to this different logic, their ever changing interpenetration on the level of the state is imbalanced. In (...) order for ‘governmentality’ to operate according to the law, it must be backed by the juridical frameworks provided by sovereign power, but then again these juridical frameworks prove inadequate and insufficient to curb ‘governmentality’s’ operational procedures as well as the modalities and intensities of its implementation. In other words, in his genealogy of the modern state, Foucault tracks down ‘governmentality’ as a distinctive form of power which, although intertwined with the state, cannot juridically be contained by the state. It cannot be appropriately restrained by its legal regulations and, as such, constitutes an excess vis-à-vis those regulations. (shrink)

We analyze investors’ perception and long-term effects of board gender diversity on firms’ stock market performance in an international setting. Our results, controlling for the endogenous nature of board compositions, indicate that female board representation neither improves nor reduces firms’ long-term stock performance. Hence, we argue that it is imperative to go beyond the conventional thinking in terms of the business case for gender diversity and broaden the perspective also to incorporate societal and ethical aspects in the strive to board (...) gender equality. Even more so, as our results show that it does not entail reduced shareholder value, which the literature on mandatory gender quotas commonly seems to suggest. (shrink)

An architect and architectural philosopher, Berlage created a series of buildings and a body of writings that probed the problems and possibilities of Modernism. His principal texts, given here in English for the first time, present a vital chapter in the history of European Modernism.

The target article presents a model for schizophrenia extending four levels of abstraction: molecules, cells, cognition, and syndrome. An important notion in the model is that of coordination, applicable to both the level of cells and of cognition. The molecular level provides an “implementation” of the coordination at the cellular level, which in turn underlies the coordination at the cognitive level, giving rise to the clinical symptoms.

The theory of reflexive modernization plausibly advocates postnational cosmopolitanism. As the nation state is eroding today, we are becoming citizens of a ‘global risk society’ whose unity and cohesion is generated by the risk that is threatening us world-wide. By the same token, this world risk society is no longer unified in any political sense. There is no world state; its very idea is even rejected. In this sense, the cosmopolitanism argued for in the theory of reflexive modernization proves predominantly (...) to be an extrapolation of civil society on a global scale, while, strictly speaking, having no cosmo‘political’ counterpart. Building on Marcel Gauchet’s political philosophy, the article questions the cosmopolitanism-beyond-the-political position of the theory of reflexive modernization. To do so, it goes substantially into Gauchet’s view of the representational role of the political as an essential dimension in society formation. (shrink)

Ancient philosophical theories of soul are in many respects sensitive to ways of speaking and thinking about the soul psuchê] that are not specifically philosophical or theoretical. We therefore begin with what the word ‘soul’ meant to speakers of Classical Greek, and what it would have been natural to think about and associate with the soul. We then turn to various Presocratic thinkers, and to the philosophical theories that are our primary concern, those of Plato (first in the Phaedo, then (...) in the Republic), Aristotle (in the De Anima or On the Soul ), Epicurus, and the Stoics. These are by far the most carefully worked out theories of soul in ancient philosophy. Later theoretical developments — for instance, in the writings of Plotinus and other Platonists, as well as the Church Fathers — are best studied against the background of the classical theories, from which, in large part, they derive.

The reliability of clinical practice guidelines has been disputed because guideline panel members are often burdened with financial conflicts of interest. Current recommendations for COI regulation advise not only detailed declaration but also active management of conflicts. To continuously assess COI declaration and management in German guidelines we established the public database LeitlinienWatch. We analyzed all German guidelines at the highest methodological level that included recommendations for pharmacological therapy according to five criteria: declaration and assessment of COI, composition of the (...) guideline development group, independence of the coordinators and lead authors, imposed abstentions because of COI and public external review. Each criterion was assessed using predefined outcome categories. Most guidelines contained a detailed declaration of COI. However, none of the guidelines provided full transparency of COI assessment results. The guideline group was composed of a majority of participants with COI in 55% of the guidelines, no guideline was free of participants with COI. Only 9% of guidelines had coordinators and lead authors without any financial COI. Most guidelines did not provide a rule for abstentions for participants with COI. In 21% of guidelines there was a rule, but abstentions were either not practiced or not documented, whereas in 7% partial abstentions and in 2% complete abstentions were documented. Two thirds of the guideline drafts were not externally reviewed via a public website. COI are usually documented in detail in German guidelines of the highest methodological level. However, considerable improvement is needed regarding active management of COI, including recruitment of independent experts for guideline projects, abstention from voting for participants with COI and external review of the guideline draft. We assume that the publicly available ratings on GuidelineWatch will improve the handling of conflicts of interest in guideline development. (shrink)

Relying on Niklas Luhmann's systems theoretical redescription of modern society, this article aims at questioning the basic theoretical notions of the ongoing inclusion/exclusion debate. The most remarkable aspect of Luhmann's reassessment of the inclusion/exclusion relationship within functionally differentiated societies is that individuals are basically situated within the exclusion domain of society, and thus cannot but partially be included within society's function systems and organizations. This reassessment not only allows Luhmann to raise fundamental questions with respect to the implicit norm of (...) full inclusion which still dominates the debate on inclusion and exclusion, but it also directs his attention to the different inclusion/exclusion conditions within function systems, organizations and interaction systems. Eventually Luhmann's position comes down to the idea that exclusion rather than inclusion is the rule, and, moreover, that inclusions differ from one another. The article closes off with a critical evaluation of Luhmann's redescription of the inclusion/exclusion debate. It is argued that systems theory might suffer from empirical deficiency, as it seems to have difficulties to detect and to depict the actual mechanisms of social exclusion without resorting to theories that are more geared to empirical reality and that are of help in observing it. Key Words: evolution • function systems • inclusion/exclusion • Niklas Luhmann • networks • organizations. (shrink)

How does one make sense of a naked prophet who walked the streets of Jerusalem for no less than three years? This contribution interpreted the ambulatory naked prophet in Isaiah 20 as a sign-act by means of symbolic interactionism and performative interpretation according to which symbolic or sign-acts are multivalent entities. Isaiah 20 was interpreted as an embodied, multivalent text that invited ongoing appropriation among subsequent audiences while exploring the potential meaning(s) of the initial act within the parameters of text (...) and context. It is presupposed that human beings reinterpret symbolic acts in different subsequent contexts and that a symbolic act should never be reduced to one single (original!) meaning – this reinterpretation process is illustrated by the Septuagint translation of Isaiah 20. Furthermore, the question will be posed how one could interpret and appropriate a disruptive and ‘foolish’ prophetic and symbolic act of public exposure – Isaiah as an ‘agent provocateur’?Contribution: The performative critique of Isaiah 20 drew attention to the neglected multivalent character of the initial sign-act that enabled ongoing appropriations (‘Fortschreibung’) in new contexts of competing power relations. At first the sign-act was relevant for its pre-exilic audience, then for the post-exilic and even later for a Hellenistic audience by means of the Septuagint version. It also illustrated that text interpretation can be a catalyst that unsettles and disrupts power (within and beyond academic and believing communities), even when it is considered folly. (shrink)
