It is well known that Niels Bohr insisted on the necessity of classical concepts in the account of quantum phenomena. But there is little consensus concerning his reasons, and what he exactly meant by this. In this paper, I re-examine Bohr’s interpretation of quantum mechanics, and argue that the necessity of the classical can be seen as part of his response to the measurement problem. More generally, I attempt to clarify Bohr’s view on the classical/quantum divide, arguing that the relation (...) between the two theories is that of mutual dependence. An important element in this clarification consists in distinguishing Bohr’s idea of the wave function as symbolic from both a purely epistemic and an ontological interpretation. Together with new evidence concerning Bohr’s conception of the wave function collapse, this sets his interpretation apart from both standard versions of the Copenhagen interpretation, and from some of the reconstructions of his view found in the literature. I conclude with a few remarks on how Bohr’s ideas make much sense also when modern developments in quantum gravity and early universe cosmology are taken into account. (shrink)

This thesis explores whether the three standard value relations, “better than”, “worse than” and “equally as good”, exhaust the possibilities in which things can relate with respect to their value. Or more precisely, whether there are examples in which one of these relations is not instantiated. There are cases in which it is not obvious that one of these relations does obtain; these are referred to as “hard cases of comparison”. These hard cases of comparison become interesting, since if it (...) not the case that the standard three value relations obtains in these cases then the three standard relations do not exhaust the possibility of instantiated value relations. It is argued that for some of the hard cases of comparison, the standard relations determinately obtain. For some it is indeterminate, due to vagueness, which of the three relations obtains, but it is determinate that one of them obtains. Thereafter it is argued that the influential Collapsing Argument fails in ruling out other accounts of the hard cases of comparison. Since one cannot depend on the Collapsing Argument in order to conclude that all items are related by the standard three relations, the investigation continues. It is argued that none of the hard cases of comparison are cases of incomparability. Furthermore, none of them are cases of a fourth basic positive value relation such as “parity”. Consequently, for all the hard cases of comparison one of the standard value relations holds, although sometimes we do not know which one and sometimes it is indeterminate which one holds. This means that there is no reason to assume that one of the standard three value relations does not hold between items we are comparing. This is followed by a brief discussion about the normative consequences of this result. The thesis ends with four different appendices in which related topics are discussed. (shrink)

This paper investigates some of the philosophical and conceptual issues raised by the search for a quantum theory of gravity. It is critically discussed whether such a theory is necessary in the first place, and how much would be accomplished if it is eventually constructed. I argue that the motivations behind, and expectations to, a theory of quantum gravity are entangled with central themes in the philosophy of science, in particular unification, reductionism, and the interpretation of quantum mechanics. I further (...) argue that there are —contrary to claims made on behalf of string theory— no good reasons to think that a quantum theory of gravity, if constructed, will provide a theory of everything, that is, a fundamental theory from which all physics in principle can be derived.

bd. 2. Æstetik fra renæssance til rokoko.

Self-organized criticality (SOC) is based upon the idea that complex behavior can develop spontaneously in certain multi-body systems whose dynamics vary abruptly. This book is a clear and concise introduction to the field of self-organized criticality, and contains an overview of the main research results. The author begins with an examination of what is meant by SOC, and the systems in which it can occur. He then presents and analyzes computer models to describe a number of systems, and he explains (...) the different mathematical formalisms developed to understand SOC. The final chapter assesses the impact of this field of study, and highlights some key areas of new research. The author assumes no previous knowledge of the field, and the book contains several exercises. It will be ideal as a textbook for graduate students taking physics, engineering, or mathematical biology courses in nonlinear science or complexity. (shrink)

This book presents the first study of the development of the theory of modal syllogistic in the Middle Ages.

This book aims at beginning the rewriting of the history of skepticism by highlightening the medieval sources of the modern skeptical discussions.

This dissertation investigates grounding, the relation of non-causal determination whereby one fact obtains in virtue of some other fact or facts. Although considerations of grounding have been central throughout Western philosophy, the last 15-20 years have seen a renaissance of systematic work on grounding in analytic philosophy. The aim of the dissertation is to contribute to our understanding of the nature of grounding and its relation to other central phenomena in metaphysics. -/- Chapter 1 of the dissertation provides a brief (...) presentation of grounding and introduces some distinctions of relevance to later chapters. Chapter 2 discusses the question of whether grounding can be reduced. Four reductive accounts – in terms of fundamentality and supervenience, essence, reduction, and metaphysical laws respectively – are considered. All of these accounts are found to be subject to objections and are consequently rejected. -/- Chapter 3 considers the relation between grounding and another important phenomenon in metaphysics, namely ontological dependence. The question of the relation between the two is approached through an investigation of their modal connection (or lack thereof). It is argued that on the common assumption that grounding is a factive relation, ontological dependence can be shown to be neither necessary nor sufficient for grounding. Furthermore, to get any form of modal connection between the two relations, one needs to move to a non-factive conception of grounding or consider generic ontological dependence and accept a potentially controversial principle about the modal behaviour of grounding. Even then, the modal connection between grounding and ontological dependence is weak and subject to qualifications. -/- Chapter 4 develops and defends the novel notion of metaphysically opaque grounding. It is commonly assumed that grounding is an especially intimate and powerful connection and enables a form of explanation that is particularly strict and illuminating. An arguably related idea is that grounding is necessarily connected with the core features of things – their essences or natures. Metaphysically opaque grounding constitutes a form of grounding that falsifies both of these ideas. Chapter 4 makes the notion of metaphysically opaque grounding precise, motivates the idea that there are genuine cases of such grounding, explores its consequences for the theory of grounding, and defends the notion from potential objections, concluding that there are currently no strong reasons to rule out opaque grounding.

A short review of some recent developments in the philosophy of physics is presented. I focus on themes which illustrate relations and points of common interest between philosophy of physics and three of its `neighboring' elds: Physics, metaphysics and general philosophy of science. The main examples discussed in these three `border areas' are decoherence and the interpretation of quantum mechanics; time in physics and metaphysics; and methodological issues surrounding the multiverse idea in modern cosmology.

This volume provides the first English translation of all the known correspondence to and from Søren Kierkegaard, including a number of his letters in draft form and papers pertaining to his life and death. These fascinating documents offer new access to the character and lifework of the gifted philosopher, theologian, and psychologist. Kierkegaard speaks often and openly about his desire to correspond, and the resulting desire to write for a greater audience. He consciously recognizes letter-writing as an opportunity to practice (...) composition. Unlike most correspondence, Kierkegaard's letters expressly "do not require a reply"--he insists on this as a principle, while he clearly and earnestly yearns for a response to his efforts. Among his other principles are purposefulness, directness, and the equality of a letter to a visit with a friend. Perhaps more than anything else in print, Kierkegaard's Letters and Documents reveal his love affair with the written word. (shrink)

One way to bring order into the often muddled picture we have of interdisciplinarity is to sort interdisciplinary projects or aims by the kinds of element that interact in encounters between researchers of the two or more disciplines involved. This is not the usual approach. Since the early seventies and the publication of Erich Jantsch , at least, the level of integration of the disciplines has been the primary focus. For instance, the level of integration is often treated as the (...) distinguishing boundary between multi‐, inter‐, and trans‐disciplinarity. We identify three kinds of interdisciplinary relation: problem‐feeding, conceptual drift, and methodological migration; we focus, in particular, on the first of these. Drawing on examples from the emerging field of Sustainability Science we show that problem‐feeding is a common and apparently fruitful way of connecting disparate disciplines. We illustrate some of the roles conceptual drift and methodological migration have in problem‐feeding as well as in their own right. Towards the end of the paper we suggest that there is an interesting difference between our approach to interdisciplinarity and the integrative perspective suggested by Jantsch. The interdisciplinarity resulting from problem‐feeding between researchers is typically local and temporary; integration is associated with a longer‐term, global form of interdisciplinarity.

Tracing increasing distrust of politicians and democratic institutions back to the negative idea of political power and freedom as always being a 'power over' and 'freedom from', this text examines Foucault's alternative conception of the politician as one who has the courage to tell people the truth about what has to be done in the face of the dangers they confront. Telling the truth is not sufficient, but must be complemented with empowering people to actively help in overcoming the dangers (...) themselves. Breaking with conceptions of politics as hierarchy and anarchy, Foucault contended that where there is obedience, there cannot be truth and genuine freedom. This book offers a redefinition of power and freedom within a circular logic of true authority and self-governance. It argues that democracy cannot survive without being innovated along these lines, and considers what can be done to reconnect politicians and laypeople in order to rebuild their mutual trust in each other's political capacities.

In On Certainty, Wittgenstein argues both that certain propositions belong to our “frame of reference” and are “exempt from doubt,” and that this “river-bed of thoughts” can change. Exploring this seeming contradiction, I argue that such changes can take place as the result of rational argumentation, although of a highly indirect nature, and suggest that something like this can hold for argumentation between cultures.

Quand, en 1936, le philosophe du droit et professeur de droit danois Alf Ross a publié un hommage à la Théorie pure du droit de Hans Kelsen dans un journal scandinave de science juridique, il s'associait à un mouvement de plus en plus présent dans la philosophie du droit européenne, qui était très critique à l'égard du « droit naturel ». Cependant, en même temps, il élaborait une critique significative de la théorie de Kelsen, qui a permis de conforter la (...) place de Ross lui-même en tant qu'imp.. (shrink)

People often fail to comply with the demands of morality. Partial compliance theory takes this noncompliance or its possibility into account in the formulation of moral requirements for people to comply with, or in the evaluation of people’s actions against those requirements. This chapter critically engages with recent work on partial compliance theory. It examines the relationship between noncompliance and injustice, assesses different ways of doing partial compliance theory, sketches the relationship between partial compliance theory and other central methodological debates (...) in moral and political philosophy, and considers whether it is reasonable to issue moral requirements without examining what would happen if everyone did their part.

Recent philosophical inquiry into the relations thought to metaphysically structure the world has largely focused on the notion of metaphysical grounding, whereas previously analytic metaphysicians tended to talk in terms of ontological dependence. This raises the question of how metaphysical grounding and ontological dependence relate to one another. In this article, I sketch a picture of grounding as a form of metaphysically substantive sufficient condition and ontological dependence as a form of metaphysically substantive necessary condition, anchored in widely accepted principles (...) for how these relations work. As a case study, I apply this picture to Jack Casey's recent attempt to reduce ontological dependence to a special case of grounding. I argue that Casey's account fails and I show how the picture of grounding and ontological dependence presented here helps us diagnose where the account goes wrong, as well as how it makes sense of the phenomena Casey's account struggles with without having to resort to any ad hoc maneuvers. Thinking of grounding as a form of metaphysically substantive sufficient condition and ontological dependence as a form of metaphysically substantive necessary condition is thus shown to help sharpen our understanding of these phenomena and provide minimal constraints on any purported reductive account of one of the phenomena in terms of the other.

Recent metaphysics has seen a surge of interest in grounding—a relation of non-causal determination underlying a distinctive kind of explanation common in philosophy. In this article, I investigate the connection between grounding and another phenomenon of great interest to metaphysics: ontological dependence. There are interesting parallels between the two phenomena: for example, both are commonly invoked through the use of “dependence” terminology, and there is a great deal of overlap in the motivations typically appealed to when introducing them. I approach (...) the question of the relationship between grounding and ontological dependence through an investigation of their modal connections. I argue, firstly, that on the common assumption that grounding is factive, it can be shown that no known variety of rigid ontological dependence is either necessary or sufficient for grounding. I also offer some suggestions in support of the claim that this generalizes to every possible form of rigid ontological dependence. I then broaden the discussion by considering a non-factive conception of grounding, as well as by looking at forms of generic ontological dependence. I argue that there is at least one form of rigid ontological dependence that is sufficient for non-factive grounding, and that a form of generic dependence may be necessary both for factive and non-factive grounding. However, justifying even these fairly weak modal connections between grounding and ontological dependence turns out to require some quite specific and substantive assumptions about the two phenomena that have only rarely been discussed.

A set of moral problems known as The Trolley Dilemmas was presented to 3000 randomly selected inhabitants of the USA, Russia and China. It is shown that Chinese are significantly less prone to support utility-maximizing alternatives, as compared to the US and Russian respondents. A number of possible explanations, as well as methodological issues pertaining to the field of surveying moral judgment and moral disagreement, are discussed.
