A model of brain function is presented that is consistently based on the biological principle of equilibrium. The neuronal modules of the cerebral cortex are proposed as units in which equilibrium between incoming signals and the synaptic structure is determined or established. Because of the electromagnetic activity of the brain, the electromagnetic properties of thecells are brought into focus. Due to the synaptic changes of the modules -essentially during sleep -an electromagnetic resting balance between the modules is established. Incoming signals (...) during the day, disturb the electromagnetic resting equilibrium and are detected and understood by this. The connecting nodes within the neuronal network are given by the equilibrium modules. Incoming information is represented in the form of the specific pathway of the network, while recognized information is represented by the equilibrium states within the modules. The paper leads to an understanding of information storage and processing in the brain. It even provides a hypothesis for understanding the emergence of the "self". Finally, the consideration of electromagnetic wave properties of neurons opens up a biophysical starting point to understanding conscious perceptions. In neuroscience, we lack a unifying theory of the brain. The reason for this may be an important detail –a missing link –that we do not yet see. Following the "track of biological equilibrium" in this paper leads to the hypothesis that the electromagnetic properties of the neurons are potential candidates to fill that gap. A hypothesis is developed describing their physiological significance in the processing of neurological information. (shrink)

Neuroenhancement involves the use of neurotechnologies to improve cognitive, affective or behavioural functioning, where these are not judged to be clinically impaired. Questions about enhancement have become one of the key topics of neuroethics over the past decade. The current study draws on in-depth public engagement activities in ten European countries giving a bottom-up perspective on the ethics and desirability of enhancement. This informed the design of an online contrastive vignette experiment that was administered to representative samples of 1000 respondents (...) in the ten countries and the United States. The experiment investigated how the gender of the protagonist, his or her level of performance, the efficacy of the enhancer and the mode of enhancement affected support for neuroenhancement in both educational and employment contexts. Of these, higher efficacy and lower performance were found to increase willingness to support enhancement. A series of commonly articulated claims about the individual and societal dimensions of neuroenhancement were derived from the public engagement activities. Underlying these claims, multivariate analysis identified two social values. The Societal/protective highlights counter normative consequences and opposes the use enhancers. The Individual/proactionary highlights opportunities and supports use. For most respondents these values are not mutually exclusive. This suggests that for many neuroenhancement is viewed simultaneously as a source of both promise and concern. (shrink)

In telling the story of Thomas Willis and the collective investigations of body and brain in 17th-century England with tremendous energy and enthusiasm, journalist Carl Zimmer has written one of the best recent books of popular history of science. The full range of readers will be rewarded by Zimmer’s synthetic scholarship and his evident pleasure in the language of the primary texts. While he owes much to the work of Robert Frank and Robert Martensen in particular, Zimmer (...) has negotiated a vast secondary literature on the major figures of early modern natural philosophy. His decision not to discuss scholarly controversy directly, but rather ‘to give accounts of these people that were consistent with the current consensus’ (p.304) is understandable given the mass market at which he has successfully aimed: yet such a voice would bring a welcome freshness to specialists’ debates.

In this article I argue that contemporary critical theory needs the conceptual tools of social ontology in order to make its own ontological commitments explicit and strengthen its interdisciplinary approach. On the other hand, contemporary analytic social ontology needs critical theory in order to be able to focus on the role that social change, power, and historicity play in the constitution of social facts, and to see the shortcomings of an agential and intentionalist approach to social facts. My thesis is (...) strengthened by a historical reconstruction of the presence of two different approaches in the original program of the family of critical theory apparently most hostile to social ontology, (the Frankfurt School), namely Horkheimer’s program of a critical social philosophy which includes a social ontology, and Adorno’s negative attitude towards it, epitomized by the paradoxical notion of “ontology of the false state”. Adorno’s negative attitude was later inherited by Habermas and Honneth, whose work I show to be nevertheless deeply laden with ontological commitments. I then argue that, if one accepts the socio-ontological redefinition of critical theory, then the post-metaphysical paradigm adopted by Habermas should be revised and a certain conception of the linguistic turn in the understanding of social action abandoned. On the side of contemporary social ontology, the impulse coming from critical theory should allow us to distinguish between forms of ‘traditional social ontology’, that simply apply ready-made general metaphysical concepts to social reality, and a ‘critical social ontology’, oriented to socializing ontology and critically transforming metaphysical categories.

Pragmatism is the distinctive contribution of American thought to philosophy. It is a movement that attracted much attention in the early part of the twentieth-century, went into decline, and reemerged in the last part of the century. Part of the difficulty in defining pragmatism is that misconceptions of what pragmatism means have abounded since its beginning, and continue in today’s “neopragmatism.”.

Deliberative politics should start from an adequate and differentiated image of our dialogical practices and their normative structures; the ideals that we eventually propose for deliberative politics should be tested against this background. In this article I will argue that equal respect, understood as respect a priori conferred on persons, is not and should not be counted as a constitutive normative ground of public discourse. Furthermore, requiring such respect, even if it might facilitate dialogue, could have negative effects and lead (...) to fallacious paths of thought –as seems to happen on matters of deep disagreement such as the Colorado Fundamentalist/Gay HIV issue I discuss in paragraph 6. I will put forward this argument from the standpoint of argumentation or discourse theory, drawing consequences for dialogical theories of politics. Basing my argument on a pluralistic notion of public discourse – understood as a mixed discourse of persuasion, information-seeking and negotiation – I will argue that respect is a dynamic, situational phenomenon, and that the norm of equal respect for persons is contextually contingent in political deliberation: equal respect should be considered as a potential outcome, a discursive achievement – which I understand as a second order consensus achieved dynamically on a provisional basis – rather than as an universal condition for dialogue.
