BackgroundTo probe the functional role of brain oscillations, transcranial alternating current stimulation has proven to be a useful neuroscientific tool. Because of the excessive tACS-caused artifact at the stimulation frequency in electroencephalography signals, tACS + EEG studies have been mostly limited to compare brain activity between recordings before and after concurrent tACS. Critically, attempts to suppress the artifact in the data cannot assure that the entire artifact is removed while brain activity is preserved. The current study aims to evaluate the (...) feasibility of specific artifact correction techniques to clean tACS-contaminated EEG data.New MethodIn the first experiment, we used a phantom head to have full control over the signal to be analyzed. Driving pre-recorded human brain-oscillation signals through a dipolar current source within the phantom, we simultaneously applied tACS and compared the performance of different artifact-correction techniques: sine subtraction, template subtraction, and signal-space projection. In the second experiment, we combined tACS and EEG on one human subject to demonstrate the best-performing data-correction approach in a proof of principle.ResultsThe tACS artifact was highly attenuated by SSP in the phantom and the human EEG; thus, we were able to recover the amplitude and phase of the oscillatory activity. In the human experiment, event-related desynchronization could be restored after correcting the artifact.Comparison With Existing MethodsThe best results were achieved with SSP, which outperformed sine subtraction and template subtraction.ConclusionOur results demonstrate the feasibility of SSP by applying it to a phantom measurement with pre-recorded signal and one human tACS + EEG dataset. For a full validation of SSP, more data are needed. (shrink)
This paper has the aim of making Johannes von Kries’s masterpiece, Die Principien der Wahrscheinlichkeitsrechnung of 1886, a little more accessible to the modern reader in three modest ways: first, it discusses the historical background to the book ; next, it summarizes the basic elements of von Kries’s approach ; and finally, it examines the so-called “principle of cogent reason” with which von Kries’s name is often identified in the English literature.
The goal of the present article is to contribute to the epistemology and methodology of computer simulations. The central thesis is that the process of simulation modeling takes the form of an explorative cooperation between experimenting and modeling. This characteristic mode of modeling turns simulations into autonomous mediators in a specific way; namely, it makes it possible for the phenomena and the data to exert a direct influence on the model. The argumentation will be illustrated by a case study of (...) the general circulation models of meteorology, the major simulation models in climate research. (shrink)
In recent years there has been much psychological and neurological work purporting to show that consciousness and self-awareness play no role in causing actions, and indeed to demonstrate that free will is an illusion. The essays in this volume subject the assumptions that motivate such claims to sustained interdisciplinary scrutiny. The book will be compulsory reading for psychologists and philosophers working on action explanation, and for anyone interested in the relation between the brain sciences and consciousness.
A multifactorial and growing crisis of health care systems in the developed world has affected medicine. In order to provide rational responses, some central concepts of the past, such as the definitions of health and disease, need to be updated. For this purpose physicians should initiate a new debate. As a point of departure the following definitions are proposed: Health is a dynamic state of wellbeing characterized by a physical, mental and social potential, which satisfies the demands of a life (...) commensurate with age, culture, and personal responsibility. If the potential is insufficient to satisfy these demands the state is disease. This term includes sickness, illness, ill health, and malady. The described potential is divided into a biologically given and a personally acquired partial potential. Their proportions vary throughout the life cycle. The proposed definitions render it empirically possible to diagnose persons as healthy or diseased and to apportion some of the responsibility for their state of health to individuals themselves. Treatment strategies should always consider three therapeutic routes: improvements of the biologically given and of the personally acquired partial potentials and adaptations of the demands of life. These consequences favourably contrast with those resulting from the WHO-definition of health. (shrink)
The question of what it means to be aware of others as subjects of mental states is often construed as the question of how we are epistemically justified in attributing mental states to others. The dominant answer to this latter question is that we are so justified in virtue of grasping the role of mental states in explaining observed behaviour. This chapter challenges this picture and formulates an alternative by reflecting on the interpretation of early joint attention interactions. It argues (...) that the standard picture is committed to an implausible account of children's awareness of the co-attender's focus of attention. On a more natural interpretation, children engaged in joint attention perceptually recognize the co-attender's attitude to some object, as something like the (correct) answer to the question of what the object is like. The developmentally basic case is not that of attributing mental states as the causes of observed behaviour but of understanding perceived attitudes and actions as appropriate responses to the shared world. The chapter concludes by exploring how this developmental claim bears on mature adult knowledge of other minds. (shrink)
We begin by considering two common ways of conceiving critical metaphysics. According to the first conception, critical metaphysics analyses nothing more than the form of thought and thereby misses the proper point of metaphysics, namely to investigate the form of reality. According to the second conception, critical metaphysics starts from the supposed insight that the form of reality can’t be other than the form of thought and it is thus not necessary to analyse anything but that form. We argue that (...) the first conception is too weak while the second is too strong. Then we sketch an alternative conception of critical metaphysics, a conception we find expressed both in Kant’s B-Deduction and in the way Barry Stroud has recently investigated the possibilities of metaphysics. According to such a conception, a properly critical metaphysics needs to proceed in two steps: first, it needs to analyze the most general and necessary form of any thought that is about an objective reality at all; second, it needs to investigate how that form of thought relates to the reality it purports to represent. But unlike Kant, Stroud remains sceptical regarding the possibility of a satisfying transition from thought to reality in metaphysics. We argue that this dissatisfaction can be traced back to a notion of objectivity and reality in terms of complete mind-independence. Then we sketch an alternative notion of objectivity and reality in terms of distinctness from subjects and acts of thinking, and argue that it is that notion that allows Kant, with his Transcendental Idealism, to make the transition required for any satisfying metaphysics, namely that from the form of thought to reality.

Johannes von Kries’s Spielraum-theory is regarded as one of the most important philosophical contributions of the nineteenth century to an objective interpretation of probability. This paper aims at a critical and contextual analysis of von Kries’s approach: It is contextual insofar as it reconstructs the Spielraum-theory in the historical setting that formed his scientific and philosophical outlook. It is critical insofar as it unfolds systematic tensions and inconsistencies which are rooted in this context, especially in the grave change of (...) mechanism which took place in the late nineteenth century. In this regard, the paper focuses on von Kries’s understanding of natural laws and nomological knowledge in relation to his concept of objective probability. While the formal approach of the Spielraum-theory—as far as developed by von Kries—seems sound, his epistemological claims with respect to nomological knowledge sustain classical mechanism and are hence difficult to substantiate from the point of view of modern science.

In this essay, Johannes Giesinger comments on the current philosophical debate on educational justice. He observes that while authors like Elizabeth Anderson and Debra Satz develop a so-called adequacy view of educational justice, Harry Brighouse and Adam Swift defend an egalitarian principle. Giesinger focuses his analysis on the main objection that is formulated, from an egalitarian perspective, against the adequacy view: that it neglects the problem of securing fair opportunities in the competition for social rewards. Giesinger meets this objection (...) by expressing two basic theses: First, he argues that Brighouse and Swift themselves fail to give an adequate account of fair competition; and, second, he shows that the adequacy view provides the theoretical resources to face this problem.

Gareth Evans famously affirmed an explanatory connection between answering the question whether p and knowing whether one believes that p. This is commonly interpreted in terms of the idea that judging that p constitutes an adequate basis for the belief that one believes that p. This paper formulates and defends an alternative, more modest interpretation, which develops from the suggestion that one can know that one believes that p in judging that p.
In a paper entitled “Emmanuel Faye: The Introduction of Fraud into Philosophy?”, Thomas Sheehan accuses Faye of committing many blunders in Heidegger: The Introduction of Nazism into Philosophy. In this paper, I address what is according to Sheehan himself the most important part of his paper, namely his charges against Faye’s interpretation of Heidegger’s Being and Time. I show that they are all wholly unfounded. All the aspects of Being and Time that Sheehan addresses speak not only not against Faye (...) but rather even for Faye. (shrink)
According to Trawny, Heidegger’s Black Notebooks show that he turned away from any National Socialism in 1938 and that his thinking could be “contaminated” by National Socialism and anti-Semitism only between 1931 and 1944/1945. However, in this paper it is argued that already in Being and Time Heidegger had made a case for National Socialism; that he discovered in 1938 the “true” National Socialism, and that Trawny’s main criterion regarding Heidegger’s anti-Semitism is false. Heidegger’s case is compared with Max Scheler, (...) who, because of Hitler, turned from the right to the centre. In addition, alternatives to Trawny’s detailed interpretations of three of Heidegger’s anti-Semitic remarks are offered, it is shown that Trawny misconstrues Heidegger’s anti-Semitism, and the anti-Semitic aspects of Heidegger’s history of Being are presented.

This article argues that in early Mīmāṃsā the view was current that there are objects in the world corresponding to all words of the Sanskrit language. Evidence to that effect is primarily found in passages from Bhartṛhari’s works, and in some classical Nyāya texts. Interestingly, Śabara’s classical work on Mīmāṃsā has abandoned this position, apparently for an entirely non-philosophical reason: the distaste felt for the newly arising group of Brahmanical temple-priests.
This paper starts by looking at the coincidence of surprising behavior on the nanolevel in both matter and simulation. It uses this coincidence to argue that the simulation approach opens up a pragmatic mode of understanding oriented toward design rules and based on a new instrumental access to complex models. Calculations, and their variation by means of explorative numerical experimentation and visualization, can give a feeling for a model's behavior and the ability to control phenomena, even if the model itself (...) remains epistemically opaque. Thus, the investigation of simulation in nanoscience provides a good example of how science is adapting to a new instrument: computer simulation. (shrink)
Commonsense epistemology regards perceptual experience as a distinctive source of knowledge of the world around us, unavailable in ‘blindsight’. This is often interpreted in terms of the idea that perceptual experience, through its representational content, provides us with justifying reasons for beliefs about the world around us. I argue that this analysis distorts the explanatory link between perceptual experience and knowledge, as we ordinarily conceive it. I propose an alternative analysis, on which representational content plays no explanatory role: we make (...) perceptual knowledge intelligible by appeal to experienced objects and features. I also present an account of how the commonsense scheme, thus interpreted, is to be defended: not by tracing the role of experience to its contribution in meeting some general condition on propositional knowledge (such as justification), but by subverting the assumption that it has to be possible to make the role of experience intelligible in terms of some such contribution.

Marketing ethics is normally marketed as a sub-specialization of business ethics. In this paper, marketing ethics serves as an umbrella term for advertising, PR and sales ethics and as an example of professional ethics. To structure the paper, four approaches are distinguished, with a focus on typical professional conflicts, codes, roles or climates respectively. Since the moral climate approachis more inclusive than the other approaches, the last part of the paper deals mainly with moral climates, within the above-mentioned marketing sub-professions.
When it comes to evaluating reductive hypotheses in metaphysics, supervenience arguments are the tools of the trade. Jaegwon Kim and Frank Jackson have argued, respectively, that strong and global supervenience are sufficient for reduction, and others have argued that supervenience theses stand in need of the kind of explanation that reductive hypotheses are particularly suited to provide. Simon Blackburn's arguments about what he claims are the specifically problematic features of the supervenience of the moral on the natural have also been (...) influential. But most discussions of these arguments have proceeded under the strong and restrictive assumptions of the S5 modal logic. In this paper we aim to remedy that defect, by illustrating in an accessible way what happens to these arguments under relaxed assumptions and why. The occasion is recent work by Ralph Wedgwood, who seeks to defend non-reductive accounts of moral and mental properties together with strong supervenience, but to evade both the arguments of Kim and Jackson and the explanatory challenge by accepting only the weaker, B, modal logic. In addition to drawing general lessons about what happens to supervenience arguments under relaxed assumptions, our goal is therefore to shed some light on both the virtues and costs of Wedgwood's proposal.
