ObjectiveIn this study we used functional magnetic resonance imaging to investigate whether motor imagery of handwriting and circle drawing activates a similar handwriting network as writing and drawing itself.MethodsEighteen healthy right-handed participants wrote the German word “Wellen” and drew continuously circles in a sitting and lying position to capture kinematic handwriting parameters such as velocity, pressure and regularity of hand movements. Afterward, they performed the same tasks during fMRI in a MI and an executed condition.ResultsThe kinematic analysis revealed a general (...) correlation of handwriting parameters during sitting and lying except of pen pressure during drawing. Writing compared to imagined writing was accompanied by an increased activity of the ipsilateral cerebellum and the contralateral sensorimotor cortex. Executed compared to imagined drawing revealed elevated activity of a fronto–parieto-temporal network. By contrasting writing and drawing directly, executed writing induced an enhanced activation of the left somatosensory and premotor area. The comparison of the MI of these tasks revealed a higher involvement of occipital activation during imagined writing.ConclusionThe kinematic results pointed to a high comparability of writing in a vertical and horizontal position. Overall, we observed highly overlapping cortical activity except of a higher involvement of motor control areas during motor execution. The sparse difference between writing and drawing can be explained by highly automatized writing in healthy individuals. (shrink)

The underdetermination of theory by evidence must be distinguished from holism. The latter is a doctrine about the testing of scientific hypotheses; the former is a thesis about empirically adequate logically incompatible global theories or "systems of the world". The distinction is crucial for an adequate assessment of the underdetermination thesis. The paper shows how some treatments of underdetermination are vitiated by failure to observe this distinction, and identifies some necessary conditions for the existence of multiple empirically equivalent global theories. (...) We consider how empiricists should respond to the possibility of such systems of the world. (shrink)

Biomedical research, especially pharmaceutical research, has been criticised for engaging in practices that lead to over-estimations of the effectiveness of medical treatments. A central issue concerns the reporting of absolute and relative measures of medical effectiveness. In this paper we critically examine proposals made by Jacob Stegenga to (a) give priority to the reporting of absolute measures over relative measures, and (b) downgrade the measures of effectiveness (effect sizes) of the treatments tested in clinical trials (Stegenga, 2015a). After exposing significant (...) flaws in a central case study used by Stegenga to bolster his first proposal (a), we go on to argue that neither of these proposals is defensible (a or b). We defend the practice, in line with the New England Journal of Medicine, of reporting both absolute and relative measures whenever feasible. (shrink)

In the Preussen contra Reich case of 1932, Carl Schmitt’s theories on equal chance and law in extreme conditions are interpreted and applied in a court of law, firstly by Schmitt himself, then, going contrary to Schmitt’s interpretation, by Dr. Arnold Brecht and Dr. Hans Peters. This paper will first present the basis of the two theories from Schmitt’s “Legality and Legitimacy,” namely, equal chance and the need for extraordinary measures. Then this paper will focus on the diverging legal (...) interpretations of these two theories, as presented in court by different legal theorists. These divergent interpretations of “equal chance” and “law in extreme conditions,” as presented in the aforementioned case, have yet to reach an international readership, as the case itself has never been fully translated into English. Finally, this paper will question the practical application of the two theories in the reality of the empirical world, which in turn question the relationship between any parliamentary legislative system and law.

In any probabilistic theory, we say that a bipartite state ω on a composite system AB steers its marginal state ω B if, for any decomposition of ω B as a mixture ω B =∑ i p i β i of states β i on B, there exists an observable {a i } on A such that the conditional states $\omega_{B|a_{i}}$ are exactly the states β i . This is always so for pure bipartite states in quantum mechanics, a fact (...) first observed by Schrödinger in 1935. Here, we show that, for weakly self-dual state spaces (those isomorphic, but perhaps not canonically isomorphic, to their dual spaces), the assumption that every state of a system A is steered by some bipartite state of a composite AA consisting of two copies of A, amounts to the homogeneity of the state cone. If the state space is actually self-dual, and not just weakly so, this implies (via the Koecher-Vinberg Theorem) that it is the self-adjoint part of a formally real Jordan algebra, and hence, quite close to being quantum mechanical.

Nature and the world can be viewed as complex volumetric computation. Historically, humans have interacted with nature in a reductive and homogeneous manner. However, inexpensive digital computation is now extending our capabilities allowing us to understand the complexity of nature and operate in and modify it as such. It is now possible to use computation to control matter, to design and fabricate natural solutions and objects creating a new class of human-made objects that allow more localized, dynamic, sustainable and natural (...) interactions with the world. Unfortunately, current digital design and fabrication systems have failed to fully capitalize on available computation. These systems are non-exact and fundamentally incapable of accurately representing real objects. Digital materialization proposes an approach, system and symbolic basis for two-way conversion between reality and information, where reality is represented as information in a dimensionally correct and exact manner and is accessible to human understanding, modification and design.

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

Samuel Alexander was one of the foremost philosophical figures of his day and has been argued by John Passmore to be one of ‘fathers’ of Australian philosophy as well as a novel kind of physicalist. Yet Alexander is now relatively neglected, his role in the genesis of Australian philosophy if far from widely accepted and the standard interpretation takes him to be an anti-physicalist. In this paper, I carefully examine these issues and show that Alexander has been (...) badly, although understandably, misjudged by most of his contemporary critics and interpreters. Most importantly, I show that Alexander offers an ingenious, and highly original, version of physicalism at the heart of which is a strikingly different view of the nature of the microphysical properties and associated view of emergent properties. My final conclusion will be that Passmore is correct in his claims both that Alexander is significant as one of the grandfather’s of Australian philosophy and that he provides a novel physicalist position. I will also suggest that Alexander’s emergentism is important for addressing the so-called ‘problem of mental causation’ presently dogging contemporary non-reductive physicalists. (shrink)

The notion of biopolitical sovereignty and the theory of the state of exception are perspectives derived from Carl Schmitt’s thought and Michel Foucault’s writings that have been popularized by critical political theorists like Giorgio Agamben and Michael Hardt and Antonio Negri of late. This article argues that these perspectives are not sufficient analytical points of departure for a critique of the contemporary politics of terror, violence and war marked by a growing global exploitation of bodies, tightened management of life, (...) and endless and unpredictable abusive force. To better capture the singularity of our present condition of violence, war and terror, a supplementation of Schmitt’s and Foucault’s approaches by way of Hannah Arendt’s language of political action and agonistic engagement is useful. By bringing Arendt’s language of political agony to bear on contemporary biopolitical debates and discourses, we wish to revisit common practices of war and terror as matters of ‘agonal sovereignty’. ‘Agonal sovereignty’ allows us to peer into the ‘abyss of total violence’ that manifests itself after sovereign decisionism and biopolitical modalities of power have taken over the everyday conduct of political affairs.

Drawing on resources from debates concerning the metaphysics of powers, this essay introduces a novel approach to the relationship between the more- and less-complex. Flat Holism preserves some key reductionist commitments, as it involves no radical ontological novelty, for instance, and is consistent with a one- or no-level ontology. It also, however, adopts the emergentist idea that the whole or context plays a crucial, metaphysically determinative role. The commitments of Flat Holism are explored and delimited through comparison with two ‘nearby (...) neighbour’ accounts: Sydney Shoemaker’s Micro-latency account and Carl Gillett’s Mutualism. Some potential advantages of Flat Holism are discussed in the final section of the essay. (shrink)

There is a relationship between time and technology which has been obvious since the classical philosophies of time. Even telling the time necessitates technologies relating to measuring and counting. Technological developments have changed the temporal state of our reality. Key terms such as deceleration, synchronisation, prevention and de-temporalisation point to relevant problem areas in this respect. This yearbook, whose thematic focus is 2021, endeavours to reveal new technological and philosophical perspectives on the temporal conditions in which we think, communicate, work (...) and live.

Mainstream economics has been accused of excessive mathematization, whereas the rejection of mathematical and other formal methods is often cited as a crucial trait of Austrian economics. Based on a systematic discussion of potential benefits and drawbacks of formalization, this paper corroborates legitimate concerns that predominant types of mathematization induce a shift of attention away from the key concepts of Austrian economics. Taking this shift to the extreme, predominant modes of mathematization tend to accompany a detachment from ‘reality’ incompatible with (...) Austrian pleas for realisticness. Contrary to popular prejudice however, the most prominent representatives of the Austrian School including Carl Menger, Ludwig Mises, Friedrich Hayek, Israel Kirzner, and Peter Boettke neither provide a justification for a wholesale rejection of formalization nor actually reject it. Adequate formalization can serve as a remedy for lacking logical and semantic rigor in standard mathematical economics as well as in murky verbal chains of reasoning. (shrink)

Carl Menger’s Principles of Economics published in 1871 is usually regarded as the founding document of the Austrian School of economics. Many of the School’s prominent representatives, including Friedrich Wieser, Eugen Böhm-Bawerk, Ludwig Mises, Hans Mayer, Friedrich August Hayek, Fritz Machlup, Oskar Morgenstern, and Gottfried Haberler, as well as Israel Kirzner, Ludwig Lachmann, Murray Rothbard, and Don Lavoie, advanced and modified Menger’s research program in sometimes conflicting ways. Yet, some characteristics of the Austrian School remain (nearly) consensual from its (...) foundation through to contemporary neo-Austrian economists. In eight sections, we will briefly discuss some of the philosophical and methodological characteristics of Austrian economics: Austrian action theory and interpretative understanding, a relatively thoroughgoing subjectivism, methodological individualism, ontological individualism, apriorism, essentialism, an often overstated rejection of formal methods, and alertness to economic semantics.

The article focuses on the overlooked volume of Henry Sumner Maine's corpus, the posthumously published International Law and uses it to respond to the general critical difficulty in establishing Maine's posture. Maine, of course, makes it difficult with the numerous contrapuntal moves of this book and others. For example, he strongly criticizes the predominant view of international law as an accretionary process of commentary by one theorist following another and yet he places tremendous value on Grotius, "whose works acted on (...) the spirit of belligerency like a charm," and other early international legal theorists. He sees his contemporary environment as marked by increasing militarization, even of militarization of society during time of peace, while he describes the relative humanity of the present over the distant past.Ultimately, Maine is a realist who focuses on late nineteenth-century manuals of war rather than the idealism of the Anglo-American peace movement, and recognizes the importance of Czar Alexander II over any of nineteenth-century international legal theorists. If J.W. Burrow has identified social evolution as providing Victorians an "intellectual resting-place" between theoretical clarity and social diversity, Maine's broad social evolution allows him to mediate between the moral amelioration in international life and the practical realities of that life.

Most contemporary political theories of sovereignty – from Giorgio Agamben to Achille Mbembe – have argued that the emergency powers claimed by the Bush administration under the auspices of the War on Terror epitomized what Carl Schmitt calls a state of exception. If so, I argue, perhaps it is time for new visions of sovereignty to emerge, ones attendant to the eccentricities of the present conjuncture. Occupy Wall Street and the Arab Spring are but two obvious examples of counterpublics (...) that seem to have presented new modalities of sovereign life worth reflecting upon. Hardly states of exception, these are scenes of sovereignty that are more fraught and precarious, more democratic. I argue that the theories of sovereignty of George Bataille and Frantz Fanon may hold clues for coming to terms with these new sovereign scenes. Though often under-emphasized in the scholarly literature on Bataille and Fanon, for both thinkers sovereignty is a condition of existence, an expression of a surreal mode of esthetic experience and poetic beauty. I argue that drawing attention to the comparison of the political thought of Bataille and Fanon, and especially to the value of surrealism for contemporary political theory generally, holds promise for those of us interested in challenging the Schmittian consensus. At stake is a refreshed understanding of sovereignty, not as norm or exception, but as a condition of political life lived by everyday subjects caught in a surreal state in-between. (shrink)

Almost all admit that there is beauty in the natural world. Many suspect that such beauty is more than an adornment of nature. Few in our contemporary world suggest that this beauty is an empirical principle of the natural world itself and instead relegate beauty to the eye and mind of the beholder. Guided by theological and scientific insight, the authors propose that such exclusion is no longer tenable, at least in the data of modern biology and in our view (...) of the natural world in general. More important, we believe an empirical aesthetics exists that can help guide experimental design and development of computational models in biology. Moreover, because theology and science can both contribute toward and equally profit from such an aesthetics, we propose that this empirical aesthetics provides the foundation for a living synergy between theology and science.

During the summer of 1774, five “electric eels” survived the voyage from Surinam to Charles Towne (Charleston), South Carolina. Naturalists knew that these river fish actually only resembled eels. They also knew that that Carl Linnaeus had recently classified them as Gymnotus electricus (Linnaeus 1766; today they are Electrophorus electricus).

Can there be grounding without necessitation? Can a fact obtain wholly in virtue of metaphysically more fundamental facts, even though there are possible worlds at which the latter facts obtain but not the former? It is an orthodoxy in recent literature about the nature of grounding, and in first-order philosophical disputes about what grounds what, that the answer is no. I will argue that the correct answer is yes. I present two novel arguments against grounding necessitarianism, and show that grounding (...) contingentism is fully compatible with the various explanatory roles that grounding is widely thought to play.

Whether or not quantum physics can account for molecular structure is a matter of considerable controversy. Three of the problems raised in this regard are the problems of molecular structure. We argue that these problems are just special cases of the measurement problem of quantum mechanics: insofar as the measurement problem is solved, the problems of molecular structure are resolved as well. In addition, we explore one consequence of our argument: that claims about the reduction or emergence of molecular structure (...) cannot be settled independently of the choice of a particular resolution to the measurement problem. Specifically, we consider how three standard putative solutions to the measurement problem inform our under- standing of a molecule in isolation, as well as of chemistry’s relation to quantum physics.

Longtermists have argued that humanity should significantly increase its efforts to prevent catastrophes like nuclear wars, pandemics, and AI disasters. But one prominent longtermist argument overshoots this conclusion: the argument also implies that humanity should reduce the risk of existential catastrophe even at extreme cost to the present generation. This overshoot means that democratic governments cannot use the longtermist argument to guide their catastrophe policy. In this paper, we show that the case for preventing catastrophe does not depend on longtermism. (...) Standard cost-benefit analysis implies that governments should spend much more on reducing catastrophic risk. We argue that a government catastrophe policy guided by cost-benefit analysis should be the goal of longtermists in the political sphere. This policy would be democratically acceptable, and it would reduce existential risk by almost as much as a strong longtermist policy. (shrink)

Carl Craver investigates what we are doing when we sue neuroscience to explain what's going on in the brain.

Jung has never pursued the "psychology of religion" apart from general psychology. The unique importance of his work lies rather in his discovery and treatment of religious, or potentially religious, factors in his investigation into the unconscious as a whole and in his general therapeutic practice. In Answer to Job , first published in Zurich in 1952, Jung employs the familiar language of theological discourse. Such terms as "God," "wisdom," and "evil" are the touchstones of his argument. And yet, Answer (...) to Job , perhaps Jung's most controversial work, is not an essay in theology as much as it is an examination of the symbolic role that theological concepts play in a person's psychic life.

Discussion of the relevance of grounding to substantiveness, theory-choice, and “location problems” in metaphysics.

Carl F. Craver investigates what we are doing when we use neuroscience to explain what's going on in the brain. When does an explanation succeed and when does it fail?

Achieving space domain awareness requires the identification, characterization, and tracking of space objects. Storing and leveraging associated space object data for purposes such as hostile threat assessment, object identification, and collision prediction and avoidance present further challenges. Space objects are characterized according to a variety of parameters including their identifiers, design specifications, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, processes, operational statuses, and associated persons, organizations, or nations. The Space Object Ontology provides a consensus-based realist framework (...) for formulating such characterizations in a computable fashion. Space object data are aligned with classes and relations in the Space Object Ontology and stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space domain awareness and the needs of spacecraft operators. This paper presents the core of the Space Object Ontology, discusses its advantages over other approaches to space object classification, and demonstrates its ability to combine diverse sets of data from multiple sources within an expandable framework. Finally, we show how the ontology provides benefits for enhancing and maintaining longterm space domain awareness. (shrink)

Some combinations of attitudes--of beliefs, credences, intentions, preferences, hopes, fears, and so on--do not fit together right: they are incoherent. A natural idea is that there are requirements of "structural rationality" that forbid us from being in these incoherent states. Yet a number of surprisingly difficult challenges arise for this idea. These challenges have recently led many philosophers to attempt to minimize or eliminate structural rationality, arguing that it is just a "shadow" of "substantive rationality"--that is, correctly responding to one's (...) reasons. -/- In *Fitting Things Together*, Alex Worsnip pushes back against this trend--defending the view that structural rationality is a genuine kind of rationality, distinct from and irreducible to substantive rationality, and tackling the most important challenges for this view. In so doing, he gives an original positive theory of the nature of coherence and structural rationality that explains how the diverse range of instances of incoherence can be unified under a general account, and how facts about coherence are normatively significant. He also shows how a failure to focus on coherence requirements as a distinctive phenomenon and distinguish them adequately from requirements of substantive rationality has led to confusion and mistakes in several substantive debates in epistemology and ethics. -/- Taken as a whole, Fitting Things Together provides the first sustained defense of the view that structural rationality is a genuine, autonomous, unified, and normatively significant phenomenon.
