Uncertainty about the actual orientation of the measurement device has been claimed to open a loophole for hidden variable models of quantum mechanics. In this paper I describe the statistics of inaccurate spin measurements by unsharp spin observables. A no‐go theorem for hidden variable models of the inaccurate measurement statistics follows: There is a finite set of directions for which not all results of inaccurate spin measurements can be predetermined in a non‐contextual way. In contrast to an earlier theorem ( (...) class='Hi'>Breuer 2002) this result does not rely on the assigment of approximate truth values, and it holds under weaker assumptions on the measurement inaccuracy.

It is shown that it is impossible for an observer to distinguish all present states of a system in which he or she is contained, irrespective of whether this system is a classical or a quantum mechanical one and irrespective of whether the time evolution is deterministic or stochastic. As a corollary, this implies that it is impossible for an observer to measure the EPR-correlations between himself or herself and an outside system. Implications of the main result are discussed for (...) how we have to conceive of universally valid theories. (shrink)

It is shown that for an inside observer it is impossible to distinguish all states in which a system was at some past time. This holds for classical and quantum systems, but an assumption of determinism is essential in the proof.

General results about restrictions on measurements from inside are applied to quantum mechanics. They imply subjective decoherence: For an apparatus it is not possible to determine whether the joint system consisting of itself and the observed system is in a statistical state with or without interference terms; it is possible that the apparatus systematically mistakes the real pure state of the joint system for the decohered state. We discuss the relevance of subjective decoherence for quantum measurements and for the problem (...) of Wigner's friend. (shrink)

John von Neumann was among the first to learn about Kurt Gödel’s results on the incompleteness of formal systems. Did this shape his views on the completeness of quantum mechanics? I will investigate this question from two viewpoints: von Neumann’s no-hidden-variables proof and his treatment of the quantum measurement problem.

Smell perception plays an important role in eating behavior and might be involved in body weight gain. Since a body of literature implies that olfactory perception and function is hampered in obesity, we here investigate neuroanatomical correlates of this phenomenon. We assessed olfactory bulb volume with magnetic resonance imaging in 67 healthy participants with a body mass index from 18.9 to 45.4 kg/m2. Moreover, we obtained psychophysiological data on olfactory ability and self-report measurements on eating behavior. Additionally, we collected parameters (...) associated with metabolic health in obesity to investigate recently proposed mechanistic explanatory models of why olfaction may be altered in obesity. We showed that OB volume was significantly lower in participants with obesity when compared to those of normal weight. Moreover, we found weak to moderate negative correlations between OB volume and BMI and related measures of metabolic health, especially leptin, body fat percentage, waist-height ratio and insulin resistance. However, neither OB volume nor BMI were related to olfactory function in our young and healthy sample. Nevertheless, our results provide first indications that obesity is associated with brain anatomical changes in the OBs. (shrink)

Philosophy of modern physics seemed not to be among the strongholds of post-war German philosophy. As this book testifies, Martin Carrier is among the few exceptions. He makes valuable and original contributions to some important problems in philosophy of science: the theory-ladenness of observation, the possibility of universally valid theories, and the status of physical geometry. I will report first on his main theses and then point to some open problems.

The author of 'Betrachtungen eines Unpolitischen' (1918) is usually regarded as one of the founding fathers of the so-called 'Conservative Revolution'. But Thomas Mann's understanding of this concept does not at all coincide with the definition established by Armin Mohler, mainly in that it is not Nietzschean. Nor do the ties with the George circle furnish grounds for assigning Mann to the 'Conservative Revol ution', any more than to the 'aesthetic fundamentalism' which was cul tivated there. Moreover, it can (...) be shown that Mann's political views differ significantly from the 'new nationalism' propagated in the circle around Arthur Moeller van den Bruck, and that they have more affini ties to old liberalism than to a 'Conservative Revolution'.

Is Plato’s philosophy still relevant for current issues in politics and political science? In order to answer this question, the contributions to this volume endeavour to re-read the Platonic dialogues and to interpret them in terms of textual hermeneutics on the one hand. On the other hand, they refer to Plato from a systematic point of view and apply his philosophy, in particular the method of Socratic dialogue, to discussions on contemporary political issues. The volume is dedicated to Barbara Zehnpfennig, (...) whose works aim at making Socratic–Platonic philosophy fruitful for the present on the basis of a new interpretation of Plato’s philosophy. With contributions by Anke Adamik, Sarah Al-Taher, Viktoria Bachmann, Philip Breuer, Johanna Falk-Seifert, Bettina Fröhlich, Benjamin A.

May lethal autonomous weapons systems—‘killer robots ’—be used in war? The majority of writers argue against their use, and those who have argued in favour have done so on a consequentialist basis. We defend the moral permissibility of killer robots, but on the basis of the non-aggregative structure of right assumed by Just War theory. This is necessary because the most important argument against killer robots, the responsibility trilemma proposed by Rob Sparrow, makes the same assumptions. We show that the (...) crucial moral question is not one of responsibility. Rather, it is whether the technology can satisfy the requirements of fairness in the re-distribution of risk. Not only is this possible in principle, but some killer robots will actually satisfy these requirements. An implication of our argument is that there is a public responsibility to regulate killer robots ’ design and manufacture. (shrink)

In this paper, I explore the question of whether the expected consequences of holding a belief can affect the rationality of doing so. Special attention is given to various ways in which one might attempt to exert some measure of control over what one believes and the normative status of the beliefs that result from the successful execution of such projects. I argue that the lessons which emerge from thinking about the case ofbelief have important implications for the way we (...) should think about the rationality of a number of other propositional attitudes,such as regret, desire, and fear. Finally,I suggest that a lack of clarity with respect to the relevant issues has given rise to a number of rather serious philosophical mistakes. (shrink)

In this book Han Thomas Adriaenssen offers the first comparative exploration of the sceptical reception of representationalism in medieval and early modern philosophy. Descartes is traditionally credited with inaugurating a new kind of scepticism by saying that the direct objects of perception are images in the mind, not external objects, but Adriaenssen shows that as early as the thirteenth century, critics had already found similar problems in Aquinas's theory of representation. He charts the attempts of philosophers in both periods (...) to grapple with these problems, and shows how in order to address the challenges of scepticism and representation, modern philosophers in the wake of Descartes often breathed new life into old ideas, remoulding them in ways that we are just beginning to understand. His book will be valuable for historians interested in the medieval background to early modern thought, and to medievalists looking at continuity with the early modern period. -/- . (shrink)

Intuitions based on the first-person perspective can easily mislead us about what is and is not conceivable.1 This point is usually made in support of familiar reductionist positions on the mind-body problem, but I believe it can be detached from that approach. It seems to me that the powerful appearance of contingency in the relation between the functioning of the physical organism and the conscious mind -- an appearance that depends directly or indirectly on the first- person perspective -- must (...) be an illusion. But the denial of this contingency should not take the form of a reductionist account of consciousness of the usual type, whereby the logical gap between the mental and the physical is closed by conceptual analysis -- in effect, by analyzing the mental in terms of the physical.

Thomas Hobbes (1588-1679) was an English philosopher, remembered today for his work on political philosophy. His 1651 book Leviathan established the foundation for most of Western political philosophy from the perspective of social contract theory. He also contributed to a diverse array of fields, including history, geometry, physics of gases, theology, ethics, general philosophy, and political science. He was one of the main philosophers who founded materialism. He visited Florence in 1636 and later was a regular debater in philosophic (...) groups in Paris, held together by Marin Mersenne. Hobbes's first area of study was an interest in the physical doctrine of motion and physical momentum. Despite his interest in this phenomenon, he disdained experimental work as in physics. He built a good reputation in philosophic circles and in 1645, he was chosen with Descartes, Gilles de Roberval and others, to referee the controversy between John Pell and Longomontanus over the problem of squaring the circle. His other works include: The Elements of Law Natural and Politic (1640) and De Cive (The Citizen): Philosophical Rudiments Concerning Government and Society (1651). (shrink)

Thomas Wheatland examines the influence of the Frankfurt School, or Horkheimer Circle, and how they influenced American social thought and postwar German sociology.

DIVBased on a series of lectures delivered in 1840, Thomas Carlyle’s On Heroes, Hero-Worship, and the Heroic in History considers the creation of heroes and the ways they exert heroic leadership. From the divine and prophetic to the poetic to the religious to the political, Carlyle investigates the mysterious qualities that elevate humans to cultural significance. By situating the text in the context of six essays by distinguished scholars that reevaluate both Carlyle’s work and his ideas, David Sorensen and (...) Brent Kinser argue that Carlyle's concept of heroism stresses the hero’s spiritual dimension. In Carlyle’s engagement with various heroic personalities, he dislodges religiosity from religion, myth from history, and truth from “quackery” as he describes the wondrous ways in which these “flowing light-fountains” unlock the heroic potential of ordinary human beings. /div.

According to the analysis of intentional action that Michael Bratman has dubbed the 'Simple View', intending to x is necessary for intentionally x-ing. Despite the plausibility of this view, there is gathering empirical evidence that when people are presented with cases involving moral considerations, they are much more likely to judge that the action (or side effect) in question was brought about intentionally than they are to judge that the agent intended to do it. This suggests that at least as (...) far as the ordinary concept of intentional action is concerned, an agent need not intend to x in order to x intentionally. (shrink)

In his recent book, Jaegwon Kim argues thatpsychophysical supervenience withoutpsychophysical reduction renders mentalcausation `unintelligible'. He also claimsthat, contrary to popular opinion, his argumentagainst supervenient mental causation cannot begeneralized so as to threaten the causalefficacy of other `higher-level' properties:e.g., the properties of special sciences likebiology. In this paper, I argue that none ofthe considerations Kim advances are sufficientto keep the supervenience argument fromgeneralizing to all higher-level properties,and that Kim's position in fact entails thatonly the properties of fundamental physicalparticles are causally efficacious.

This book presents a radical and intuitive argument against the notion that intentional action, agency and autonomy are features belonging only to humans. Using evidence from research into the minds of non-human animals, it explores the ways in which animals can be understood as individuals who are aware of themselves, and the consequent basis of our moral obligations towards them. The first part of this book argues for a conception of agency in animals that admits to degrees among individuals and (...) across species. It explores self-awareness and its various levels of complexity which depend on an animals’ other mental capacities. The author offers an overview of some established theories in animal ethics including those of Peter Singer, Tom Regan, Bernard Rollin and Lori Gruen, and the ways these theories serve to extend moral consideration towards animals based on various capacities that both animals and humans have in common. The book concludes by challenging traditional Kantian notions of rationality and what it means to be an autonomous individual, and discussing the problems that still remain in the study of animal ethics.

Though it enjoys widespread support, the claim that perceptual experiences possess nonconceptual content has been vigorously disputed in the recent literature by those who argue that the content of perceptual experience must be conceptual content. Nonconceptualism and conceptualism are often assumed to be well-defined theoretical approaches that each constitute unitary claims about the contents of experience. In this paper I try to show that this implicit assumption is mistaken, and what consequences this has for the debate about perceptual experience. I (...) distinguish between two different ways that nonconceptualist proposals about perceptual content can be understood: as claims about the constituents that compose perceptual contents or as claims about whether a subject’s undergoing experiences with those contents requires them to possess the concepts that characterize those contents. I maintain that these ways of understanding conceptualism and nonconceptualism are orthogonal to one another. This is revealed by the conceptual coherence of positions in which the contents of experiences have both conceptual and nonconceptual features; positions which possess their own distinctive sources of philosophical motivation. I argue that the fact that there is a place in conceptual space for such positions, and that there may be good reason for theorists to adopt them, creates difficulties for both the central argument for nonconceptualism and the central argument for conceptualism. I set out each of these arguments; the Argument from Possession-Independence and the Epistemically-Driven Argument. I then try to show how the existence of mixed positions about perceptual content derived from a clear distinction between compositional and possessional considerations constitutes a significant obstacle for those arguments as they stand. The takehome message of the paper is that unless one clearly acknowledges the distinction between issues about the composition of perceptual content and issues about how subject’s capacities to undergo certain experiences relates to their possession of concepts one runs the risk of embracing unsatisfying philosophical arguments in which conclusions relevant to one conception of nonconceptual and conceptual content are grounded on arguments that concern only the other; arguments that cannot, in themselves, sustain them.

Rhetoric is widely regarded by both its detractors and advocates as a kind of antithesis to reason. In this book Thomas B. Farrell restores rhetoric as an art of practical reason and enlightened civic participation, grounding it in its classical tradition—particularly in the rhetoric of Aristotle. And, because prevailing modernist world views bear principal responsibility for the disparagement of rhetorical tradition, Farrell also offers a critique of the dominant currents of modern humanist thought. Farrell argues that rhetoric is not (...) antithetical to reason but is a manner of posing and answering questions that is distinct from the approaches of analytic and dialectical reason. He develops this position in a number of ways: through a series of bold reinterpretations of Aristotle's _Rhetoric_; through a detailed appraisal of traditional rhetorical concepts as seen in modern texts from the Army-McCarthy hearings to Edward Kennedy's memorial for his brother, Mario Cuomo's address on abortion, Betty Friedan's _Feminine Mystique_, and Vaclav Havel's inaugural address; and through a fresh appraisal of theories on the character of language and discourse found in contemporary philosophy, literary criticism, anthropology, deconstructionism, Marxism, and especially in Habermas's critical theory of communicative action.

Sarah Kofman, Professor of Philosophy at the Sorbonne in Paris and the author of over twenty books, was one of the most significant postwar thinkers in France. Kofman's scholarship was wide-ranging and included work on Freud and psychoanalysis, Nietzsche, feminism and the role of women in Western philosophy, visual art, and literature. The child of Polish Jewish immigrants who lost her father in the Holocaust, she also was interested in Judaism and anti-Semitism, especially as reflected in works of literature and (...) philosophy. This book is an anthology of some of Kofman's most significant writings on these and other topics. Its purpose is to provide a general introduction to Kofman's thought, which has been highly influential in both Europe and America. Although some of the selections have been published previously, the majority of the books contents appear in English translation for the first time. (shrink)

While Good’s book forces us to recognize the caricatures of Hegel and idealism that have dominated Anglo-American thought, Dewey’s relationship with idealism in general and Hegel in particular remains complex. Good proposes that the main reason for Dewey’s rejection of idealism was World War I. I find this implausible. Good downplays the central influence of James on Dewey, first with the Principles and then with his radical empiricism. By his move to Columbia in 1905 and in his article of that (...) year, “The Postulate of Immediate Empiricism,” Dewey had rejected all types of philosophy that equated reality with the object of knowledge, including idealism and Hegel. For Dewey, reality includes types of experiences that are not instances of knowing and that ideals, functionally understood, are possibilities, not actualities. (shrink)
