Individuals regaining reliable day-to-day walking function after incomplete spinal cord injury report persisting unsteadiness when confronted with walking challenges. However, quantifiable measures of walking capacity lack the sensitivity to reveal underlying impairments of supra-spinal locomotor control. This study investigates the relationship between intramuscular coherence and corticospinal dynamic balance control during a visually guided Target walking treadmill task. In thirteen individuals with iSCI and 24 controls, intramuscular coherence and cumulant densities were estimated from pairs of Tibialis anterior surface EMG recordings during (...) normal treadmill walking and a Target walking task. The approximate center of mass was calculated from pelvis markers. Spearman rank correlations were performed to evaluate the relationship between intramuscular coherence, clinical parameters, and center of mass parameters. In controls, we found that the Target walking task results in increased high-frequency intramuscular coherence, which negatively related to changes in the center of mass movement, whereas this modulation was largely reduced in individuals with iSCI. The impaired modulation of high-frequency intramuscular coherence during the Target walking task correlated with neurophysiological and functional readouts, such as motor-evoked potential amplitude and outdoor mobility score, as well as center of mass trajectory length. The Target walking effect, the difference between Target and Normal walking intramuscular coherence, was significantly higher in controls than in individuals with iSCI [F = 13.042, p < 0.001]. Intramuscular coherence obtained during challenging walking in individuals with iSCI may provide information on corticospinal gait control. The relationships between biomechanics, clinical scores, and neurophysiology suggest that intramuscular coherence assessed during challenging tasks may be meaningful for understanding impaired supra-spinal control in individuals with iSCI.

Der Nationalökonom Moritz Julius Bonn (1873-1965) gehörte zu den bekanntesten politischen Intellektuellen seiner Epoche. Bonn fungierte als Gesandter der Reichsregierung in Versailles und auf zahlreichen Konferenzen zur Reparationsfrage. Max Weber und Carl Schmitt haben ihn hoch geschätzt, Harald Laski hielt ihn für den besten Amerika-Kenner seit Toqueville. Erstaunlicherweise hat sich mit seinem Gang ins Exil seine Spur weitgehend verloren. Es ist höchste Zeit, an diesen kosmopolitischen Liberalen und mit ihm an die vergebene Chance der Weimarer Republik zu erinnern. (...) Er stritt für den Parlamentarismus, den demokratischen Rechtsstaat, sozialen Pluralismus, die europäische Aussöhnung und die Zähmung des Kapitalismus. Erstmals sind in diesem Band die wichtigsten Schriften der Weimarer Epoche vereint, darunter auch sein klassischer Essay Die Krisis der europäischen Demokratie, der 1925 zeitgleich in England, den USA, Frankreich und Spanien erschienen war.

Viennese Brain Research and the Formation of Austrian Positivism. In this paper, I want to argue that the Vienna School of Medicine and especially the Viennese Brain Anatomy had an impact on the formation of the Austrian positivism. I argue that Carl von Rokitansky's (1804–1878) doctrine that psychological phenomena must be translated into anatomical facts and Theodor Meynert's (1833–1892) theory of brain functions served as one basis for the formation of the Austrian positivism. In this sense, two of the (...) main early positivistic thinkers, Ernst Mach (1838–1916) and Richard Wahle (1857–1935), used Meynert's brain theory to argue for a bundle view of the Self. Friedrich Jodl (1849–1914) also thought about his theory, and even Moritz Schlick (1882–1936) who demanded a ‘reduction of the psychology to the brain physiology’ grappled with this approach. Meynert, a scholar of Rokitansky, the founder of the Vienna School of Medicine, was a leading figure in the history of neurology and has made several significant contributions to this discipline. He argues that the Self does not exist from an anatomical point of view. As Richard Wahle tells us, Meynert's theory of the brain functions was widely accepted under the brain researchers by the end of the nineteenth century and at the beginning of the twentieth century. He makes clear that brain researchers did in common refer to Meynert's theory to explain psychical functions as brain functions. He says from their point of view there was no doubt about it. Mach talks about Meynert's theory in Erkenntnis und Irrtum. There he says that Meynert's brain theory explains the nature and conditions of the consciousness. Michael Hagner argues that Mach's “Das Ich ist unrettbar” is hardly imaginable without the cerebral embedding of the mental functions. (shrink)

An Introduction to Carl Stumpf's influences over other philosophers.

Summary During his prolific career, the German Jewish scientist Franz Boas (Minden, 1858 - New York, 1942) recognized as the founding father of American Cultural Anthropology – maintained assiduous contacts with the European scientific community, in a privileged way with that of the German area. The contribution addresses the Boasian correspondence with the two directors of the Berliner Phonogramm-Archiv, the philosopher and psychologist Carl Stumpf, and the ethnomusicolo-gist Erich Moritz von Hornbostel. All three were united by a common (...) scientific experimental training and a solid musical education, typical of their Bildungsbu ü rgertum. With them, Boas consistently shared his fieldwork findings regarding music, sound, and language among the Indians of British Columbia: indeed, their epistolary exchanges intertwine epistemological reflections centered on the study of «exotische Musik» in context with technical problems, derived from the use of phonographic recordings and the relative shipments of wax cylinders by Boas to the Phonographic Archive. So far, the critical literature has not paid particular attention to their correspondence, that offer instead a privileged look in observing the birth of Ethnomusicology, at the time still defined as comparative Musicology (vergleichende Musikwissenschaft). Starting from a biographical contextualization and following the micro-history of the scientific and personal relationship of these scientists, the contribution aims to explore the hypothesis that the emerging Ethnomusicology significantly contributed to the definition of Cultural Anthropology as a discipline. In his painstaking research devoted to the Native Indian sounds and languages, Boas observed indeed what happens if a mind is exposed to a new sound, musical or linguistic context; he had therefore to rigorously deal with the phenomena of mishearing, sound-blindness and biasing filter related to the perception of «new sounds». Thanks to his fieldwork, Boas would endorse a relativistic and “in context” approach to perception and mental representations of sounds, fostering his eventual lifelong, hectic concern about a broaden antiracist theory of human mental functions.

Do the terms “logical positivism” and “logical empiricism” mark a philosophically real and significant distinction? There is, of course, no doubt that the first term designates the group of philosophers known as the Vienna Circle, headed by Moritz Schlick and including Rudolf Carnap, Herbert Feigl, Philipp Frank, Hans Hahn, Otto Neurath, Friedrich Waismann and others. What is debatable, however, is whether the name “logical positivism” correctly distinguishes their doctrines from related ones called “logical empiricism” that emerged from the Berlin (...) Society for Scientific Philosophy around Hans Reichenbach which included Walter Dubislav, Kurt Grelling, Kurt Lewin and a young Carl Gustav Hempel.1 The .. (shrink)

With In Search of Mechanisms, Carl F. Craver and Lindley Darden offer both a descriptive and an instructional account of how biologists discover mechanisms. Drawing on examples from across the life sciences and through the centuries, Craver and Darden compile an impressive toolbox of strategies that biologists have used and will use again to reveal the mechanisms that produce, underlie, or maintain the phenomena characteristic of living things. They discuss the questions that figure in the search for mechanisms, characterizing (...) the experimental, observational, and conceptual considerations used to answer them, all the while providing examples from the history of biology to highlight the kinds of evidence and reasoning strategies employed to assess mechanisms. At a deeper level, Craver and Darden pose a systematic view of what biology is, of how biology makes progress, of how biological discoveries are and might be made, and of why knowledge of biological mechanisms is important for the future of the human species.

Philosophers of neuroscience have traditionally described interfield integration using reduction models. Such models describe formal inferential relations between theories at different levels. I argue against reduction and for a mechanistic model of interfield integration. According to the mechanistic model, different fields integrate their research by adding constraints on a multilevel description of a mechanism. Mechanistic integration may occur at a given level or in the effort to build a theory that oscillates among several levels. I develop this alternative model using (...) a putative exemplar of reduction in contemporary neuroscience: the relationship between the psychological phenomena of learning and memory and the electrophysiological phenomenon known as Long-Term Potentiation. A new look at this historical episode reveals the relative virtues of the mechanistic model over reduction as an account of interfield integration. (shrink)

Carl Schmitt, the author of such books as Political Theology and The Crisis of Parliamentary Democracy, was one of the leading political and legal theorists of the twentieth century. His critical discussions of liberal democratic ideals and institutions continue to arouse controversy, but even his opponents concede his uncanny sense for the basic problems of modern politics. Political Romanticism is a historical study that, like all of Schmitt's major works, offers a fundamental political critique. In it, he defends a (...) concept of political action based on notions of good and evil, justice and injustice, and attacks the political passivity entailed by the romanticization of experience. The book has three strands. The first is an attack on received notions of the origins of the Romantic Movement. Schmitt argues that this movement represents a secularization, subjectification, and privatization in which God is replaced by the emancipated, private individual of the bourgeois social order. The second is an assault on political romanticism that includes a broader attack on the new European bourgeoisie, which Schmitt characterizes as the historical bearer of the movement. The third strand is a defense of political conservatism and a refutation of the view that political romanticism is intrinsically linked with romanticism. Here Schmitt argues that the political romantic is tied not to positions but to aesthetics, and can therefore as easily become a Danton as a Frederick the Great. Guy Oakes's introduction places the book in historical context and also suggests its continuing relevance through his discussion of the latest outcropping of political romanticism in the late 1960s, intriguingly brought out in his example of Norman Mailer as a political romantic.

The lecture is an argument for a marriage of theory and experience. It contains something old, something new, something borrowed and something true. The argument is that the dichotomy between science and art, between theory and experience is resolved and the components unified when the role of consensus in the acceptance of theory and the conception of experience is made clear. Moreover, the unification achieved brings with it a method for unifying the empiricism of Moritz Schlick1 with the consensualism (...) of Otto Neurath.2 In earlier work, I developed a mathematical model of consensus with Carl Wagner. That work concerned the aggregation of probabilities by weights of respect assigned by members of a community to each other that converged toward a consensual probability. The convergence depended on connectedness among the members of the group in terms of positive weights. We thought of the probabilities as probabilities of scientific theories or hypotheses. The process converging toward consensus was mathematically equivalent to finding consensual weights to be assigned to members of the group that could be used as a measure of competence and expertise. The consensual weights can be applied to find consensus concerning factors other than probabilities. The use of probabilities was in fact an incidental, though formally well articulated, application of the underlying aggregation of weights to obtain convergence toward consensual weights. (shrink)

Carl Schmitt kept diaries throughout his life, several of which he specifically selected for academic publication. These are the recordings made in the early years after World War II, when Schmitt lost all his positions. After his release from the prison he returned to his home in small town of Plettenberg, where he remained until his death. Schmitt ordered these diaries to be published only after his death, because, even several decades after the war, they remained ideologically dangerous. In (...) this issue we continue to publish fragments of translation of the “Glossarium”. In the fragments prepared for present publication, Schmitt argues on several important topics. First, he writes about utopia — paradise located in a remote, but achievable future. The ability to think future located at long distance decreases in modern times. Therefore, in the 19th century they have to move from utopia to positive science. Those who write on future must say that heaven can come tomorrow. Schmitt goes further to compare the utopian ideas of Thomas More with the utopias of the 19th century. More was not a cleric; he was just a clerk, an intellectual, a writer, not a priest. Schmitt questioned the rightfulness of the canonization of More and compared him with another Catholic thinker of that time, Fr. Vitoria. Another important topic — the problem of legality and legitimacy. Schmitt once again handles it in connection with the events in Czechoslovakia in 1948. These events he contrasts with the situation in Germany in 1929-1932. (shrink)

To enlarge the discussion of scientific responsibility for research integrity, this paper offers two historico-philosophical observations. First, in the broad history of ideas, modern ethics replaces social role responsibility with appeals to abstract principles; by contrast, discussions within the scientific community of responsibility for research integrity constitute a rediscovery of the continuing vitality of role responsibility. This is a rediscovery from which philosophy itself may benefit. Second, within the context of scientists’ concerns, the idea of role responsibility has undergone significant (...) evolution from “collective responsibility” to the notion of responsibility resting with a “trans-scientific community.” Further challenges nevertheless remain in order to relate scientific role responsibility for scientific integrity to the relationship between science and society. To promote a notion of integrity not just in science but in the science-society relationship, it may be useful to think in terms of a “co-responsibility” for scientific integrity. (shrink)

The aim of this paper is twofold: In its first part, we work out the key features of constitutivism as presented by Christine Korsgaard. This reconstruction serves to clarify which goals Korsgaard wants to achieve with her account and which of its central claims she has to defend in particular. In the second part, we discuss whether Korsgaard can vindicate constitutivism's most central claim. To do this, we analyse two important arguments - the argument from unavoidability and the argument from (...) the abstract constitutive principle - that have been made in support of constitutivism. We show how both these arguments go amiss and conclude that at least for now, constitutivism's most central claim has not been successfully argued for. (shrink)

Carl Gustav Hempel (1905-1997) was one of the preeminent figures in the philosophical movement of logical empiricism. He was a member of both the Berlin and Vienna circles, fled Germany in 1934 and finally settled in the US where he taught for many years in New York, Princeton, and Pittsburgh. The essays in this collection come from the early and late periods of Hempel's career and chart his intellectual odyssey from a rigorous commitment to logical positivism in the 1930s (...) (when Hempel allied himself closely with Carnap) to a more sociological approach close in spirit to the work of Neurath and Kuhn. The collection brings together essays which have up till now been difficult to find, four of which are appearing in English for the first time. Cumulatively they offer a fresh perspective on Hempel's intellectual development and on the rise and demise of logical empiricism. (shrink)

Carl Hausman presents here a sustained and systematic examination of the problems of constructing a framework for understanding the concept of creativity. His discussion is unique in focusing systematically on problems of understanding creativity, examining our assumptions about what we take to be creative, and the possibility of seeing how creativity fits into a world that we expect to behave in rational patterns. In a careful examination of this complex phenomena, Hausman suggests a way of approaching creativity in terms (...) of a novel theory of metaphor. (shrink)

In this paper, we review recent neuroimaging investigations of disorders of consciousness and different disciplines' understanding of consciousness itself. We consider potential tests of consciousness, their legal significance, and how they map onto broader themes in U.S. statutory law pertaining to advance directives and surrogate decision-making. In the process, we outline a taxonomy of themes to illustrate and clarify the variance in state-law definitions of consciousness. Finally, we discuss broader scientific, ethical, and legal issues associated with the advent of neuroimaging (...) for disorders of consciousness and conclude with policy recommendations that could help to mitigate confusion in this realm.

This paper gives a formalization of general topology in second-order arithmetic using countably based MF spaces. This formalization is used to study the reverse mathematics of general topology. For each poset P we let MF denote the set of maximal filters on P endowed with the topology generated by {Np | p ∈ P}, where Np = {F ∈ MF | p ∈ F}. We define a countably based MF space to be a space of the form MF for some (...) countable poset P. The class of countably based MF spaces includes all complete separable metric spaces as well as many nonmetrizable spaces. The following reverse mathematics results are obtained. The proposition that every nonempty Gδ subset of a countably based MF space is homeomorphic to a countably based MF space is equivalent to [Formula: see text] over ACA0. The proposition that every uncountable closed subset of a countably based MF space contains a perfect set is equivalent over [Formula: see text] to the proposition that [Formula: see text] is countable for all A ⊆ ℕ. The proposition that every regular countably based MF space is homeomorphic to a complete separable metric space is equivalent to [Formula: see text] over [Formula: see text]. (shrink)

It is a common assumption in contemporary cognitive neuroscience that discovering a putative realized kind to be dissociably realized (i.e., to be realized in each instance by two or more distinct realizers) mandates splitting that kind. Here I explore some limits on this inference using two deceptively similar examples: the dissociation of declarative and procedural memory and Ramachandran's argument that the self is an illusion.

Several authors have made the argument that because blind evolutionary processes produced human intelligence on Earth, it should be feasible for clever human engineers to create human-level artificial intelligence in the not-too-distant future. This evolutionary argument, however, has ignored the observation selection effect that guarantees that observers will see intelligent life having arisen on their planet no matter how hard it is for intelligent life to evolve on any given Earth-like planet. We explore how the evolutionary argument might be salvaged (...) from this objection, using a variety of considerations from observation selection theory and analysis of specific timing features and instances of convergent evolution in the terrestrial evolutionary record. We find that, depending on the resolution of disputed questions in observation selection theory, the objection can either be wholly or moderately defused, although other challenges for the evolutionary argument remain.

Infinite time register machines (ITRMs) are register machines which act on natural numbers and which are allowed to run for arbitrarily many ordinal steps. Successor steps are determined by standard register machine commands. At limit times register contents are defined by appropriate limit operations. In this paper, we examine the ITRMs introduced by the third and fourth author (Koepke and Miller in Logic and Theory of Algorithms LNCS, pp. 306–315, 2008), where a register content at a limit time is set (...) to the lim inf of previous register contents if that limit is finite; otherwise the register is reset to 0. The theory of these machines has several similarities to the infinite time Turing machines (ITTMs) of Hamkins and Lewis. The machines can decide all ${\Pi^1_1}$ sets, yet are strictly weaker than ITTMs. As in the ITTM situation, we introduce a notion of ITRM-clockable ordinals corresponding to the running times of computations. These form a transitive initial segment of the ordinals. Furthermore we prove a Lost Melody theorem: there is a real r such that there is a program P that halts on the empty input for all oracle contents and outputs 1 iff the oracle number is r, but no program can decide for every natural number n whether or not ${n \in r}$ with the empty oracle. In an earlier paper, the third author considered another type of machines where registers were not reset at infinite lim inf’s and he called them infinite time register machines. Because the resetting machines correspond much better to ITTMs we hold that in future the resetting register machines should be called ITRMs. (shrink)

The interest contemporary philosophy takes in Kant's notion of apperception is restricted to his criticism of the Cartesian Ego and to his refutation of scepticism, but there is a profound lack of concern for the notion itself and for the act of spontaneity in particular which is connected with the use of the word T. Starting from a comparison of Wittgenstein's account of this use with Kant's considerations it is argued that the latter aims at a theory of formal conditions (...) of knowledge which includes the availability of the notion of the I. It is clarified what the determination of apperception as an 'act of spontaniety' amounts to (B: 132). Kant's scattered remarks on the ability of having the representation of the I, of using the word 'I', are considered in order to show that what he called 'the logical I' has something to do with the capacity of performing an act of judgment. It is argued that such an account is not to be found in contemporary discussions of 'essential indexicals', 'first-person view' and mental self-ascriptions. (shrink)

Building on research in anthropology and philosophy, one can make a distinction between type I and type II energy ethics as a framework for advancing public debate about energy. Type I holds energy production and use as a fundamental good and is grounded in the assumption that increases in energy production and consumption result in increases in human wellbeing. Conversely, type II questions the linear relationship between energy production and progress by examining questions of equity and human happiness. The type (...) I versus type II framework helps to advance public debates about energy that address broad questions of profitability, regulation, and the environment, and in the process poses fundamental questions about the reverence for energy growth in advanced technological societies.

1. Object of this note . In his lively essay, “Between Analytic and Empirical,” , Mr. J. W. N. Watkins challenges the empiricist identification of synthetic statements with empirical ones by arguing that there exists an important class of statements which are synthetic, i.e. not analytically true or false, and yet not empirical. I find Mr. Watkins's arguments very stimulating, but I do not think they provide a sound basis for his contention. In the present note, I wish to indicate (...) what seem to me the principal flaws in Mr. Watkins's reasoning, and to make some additional comments on the issues raised by his discussion. (shrink)

In a recent issue of The Lancet, the historian Roger Cooter predicted that the field of bioethics will soon die of self-inflicted wounds. “Conspiring against it,” he wrote, “is exposure of the funding of some of its US centres by pharmaceutical companies; exclusion of alternative perspectives from the social sciences; retention of narrow analytical notions of ethics in the face of popular expression and academic respect for the place of emotions; divisions within the discipline ; and collusion with, and appropriation (...) by, clinical medicine.” Cooter's prognosis? “Hardly wet behind the ears, bioethics seems destined for a short lifespan.”.

Environmentalists have advocated the Precautionary Principle (PP) to help guide public and private decisions about the environment. By contrast, industry and its spokesmen have opposed this. There is not one principle, but many that have been recommended for this purpose. Despite the attractiveness of a core idea in all versions of the principle—that decision-makers should take some precautionary steps to ensure that threats of serious and irreversible damage to the environment and public health do not materialize into harm—even one of (...) the most widely endorsed principles needs considerable specification and refinement before it can be used. Moreover, the PP is an approach or guide to utilizing scientific evidence in social or legal decision-making contexts. In this it does not differ in kind from other approaches to using factual information such as in the law. The law provides some models for different strategies to guide decision-making under uncertainty when factual issues cannot be resolved with certainty. These in turn can help guide the formulation of different versions of PP and help clarify some presuppositions of the principle. Once some plausible versions of PP are articulated, I suggest some applications to existing environmental problems. (shrink)

English summary: In moral and juridical contexts omissions are phenomena of high normative relevance. However, they are rather unwieldy for reconstructions based on action and causation theory and therefore also for a normative evaluation. From the perspective of action theory, the question of how the concepts of 'omission' and 'action' relate to one another is of particular interest: are these contrasting terms, or does the concept of 'action' comprise its negative counterpart? Even more significant in the normative debate on omissions, (...) however, is the question of whether they may have consequences. Carl Bottek argues that although there is no plausible theory of causation, the relevant theories have no difficulty in seeing omissions as causally relevant. Such considerations are, for example, of importance for the assessment of passive euthanasia. German description: Unterlassungen sind Phanomene, denen in moralischen und juridischen Kontexten eine hohe normative Relevanz zukommt. Sie erweisen sich aber als ausgesprochen sperrig fur handlungs- und kausalitatstheoretische Rekonstruktionen und folglich fur die normative Bewertung.Aus handlungstheoretischer Perspektive interessiert besonders die Frage, wie die Begriffe 'Unterlassung' und 'Handlung' zueinander stehen: Sind es Kontrastbegriffe, oder schliesst der Handlungsbegriff sein negatives Pendant mit ein? Noch weitaus wichtiger fur die normative Beschaftigung mit Unterlassungen ist aber die Frage, ob diese Folgen haben konnen. Carl Bottek argumentiert, dass zwar einerseits keine plausible Kausalitatstheorie vorliegt, andererseits aber die interessanten Theorieangebote keine Schwierigkeiten damit haben, Unterlassungen als kausal relevant anzusehen. Diese Uberlegungen sind zum Beispiel fur die Bewertung passiver Sterbehilfe von Bedeutung. (shrink)

Garber (1983) and Jeffrey (1991, 1995) have both proposed solutions to the old evidence problem. Jeffrey's solution, based on a new probability revision method called reparation, has been generalized to the case of uncertain old evidence and probabilistic new explanation in Wagner 1997, 1999. The present paper reformulates some of the latter work, highlighting the central role of Bayes factors and their associated uniformity principle, and extending the analysis to the case in which an hypothesis bears on a countable family (...) of evidentiary propositions. This extension shows that no Garber-type approach is capable of reproducing the results of generalized reparation. (shrink)
