Hemiparetic stroke in adulthood often results in the grouped movement pattern of the upper extremity flexion synergy thought to arise from an increased reliance on cortico-reticulospinal pathways due to a loss of lateral corticospinal projections. It is well-established that the flexion synergy induces reaching constraints in individuals with adult-onset hemiplegia. The expression of the flexion synergy in individuals with brain injuries onset earlier in the lifespan is currently unknown. An early unilateral brain injury occurring prior to six months post full-term (...) may preserve corticospinal projections which can be used for independent joint control and thus minimizing the expression of the flexion synergy. This study uses kinematics of a ballistic reaching task to evaluate the expression of the flexion synergy in individuals with pediatric-onset hemiplegia (PH) ages six to seventeen years. Fifteen individuals with brain injuries before birth (n = 8) and around full-term (n = 7) and nine age-matched controls with no known neurological impairment completed a set of reaches in an admittance controlled robotic device. Descending drive, and the possible expression of the upper extremity flexion snergy, was modulated by increasing shoulder abduction loading. Individuals with early PH achieved lower peak velocities when reaching with the paretic arm compared to controls however no differences in reaching distance were found between groups. Relative maintenance in reaching seen in individuals with early brain injuries highlights minimal expression of the flexion synergy. We interpret this conservation of independent control of the paretic shoulder and elbow as the use of more direct corticospinal projections instead of indirect cortico-reticulospinal pathways used in individuals with adult-onset hemiplegia.

This paper suggests, against a comparative horizon and in broadly philosophical context, a fresh approach to the study of Hinduism. After indicating how religion in general and ‘Hinduism’ in particular are plural phenomena both internally and externally, the paper goes on to define a distinguishing property of Hinduness in terms of an approach that is based on a re-centring system of equilibrating and interactive polarities called ‘polycentrism’. This is described further as a calculated paradoxicality, which is articulated in the light (...) of possible objections. (shrink)

The increasing prevalence of ecologically sustainable products in consumer markets, such as organic produce, are generally assumed to curtail anthropogenic impacts on the environment. Here I intend to present an alternative perspective on sustainable production by interpreting the relationship between recent rises in organic agriculture and greenhouse gas emissions from agricultural production. I construct two time series fixed-effects panel regressions to estimate how increases in organic farmland impact greenhouse gas emissions derived from agricultural production. My analysis finds that the rise (...) of certified organic production in the United States is not correlated with declines in greenhouse gas emissions derived specifically from agricultural production, and on the contrary is associated positively overall agricultural greenhouse gas emissions. To make sense of this finding, I embed my research within the conventionalization thesis. As a result I argue that the recent USDA certification of organic farming has generated a bifurcated organic market, where one form of organic farming works as a sustainable counterforce to conventional agriculture and the other works to increase the economic accessibility of organic farming through weakening practice standards most conducive to reducing agricultural greenhouse gas output. Additionally, I construct my own theoretical framework known as the displacement paradox to further interpret my findings. (shrink)

Liebe Grete Herrmann, besten Dank für Ihren Brief vom 19.5! Auch ich freue mich, Sie auf dem Pariser Kongreß zu sehen; wahrscheinlich werde ich auch an der vorangehenden Positivistentagung teilnehmen, also schon am 29.7. in Paris sein. Es interessiert mich, diese antimetaphysischen Metaphysiker einmal aus der Nähe zu beobachten. Ich werde sehen, es so einzurichten, daß ich eventuell auch nach dem Hauptkongreß noch einige Tage in Paris sein kann, um die von Ihnen angeregten Diskussionen mitzuführen. Jedenfalls hoffe ich auf einige (...) gründliche Gespräche mit Ihnen. (shrink)

Zu den wichtigsten Entwicklungen der Diskussion der Frage, ob Freiheit und moralische Verantwortung einerseits, und der Determinismus andererseits miteinander vereinbar sind, zählen nach verbreiteter Ansicht die Überwindung der Konditionalanalyse von Freiheit, sowie der wachsende Zweifel daran, dass alternative Möglichkeiten Voraussetzung für Verantwortung sind. In meiner Habilitationsschrift versuche ich zu zeigen, dass beide Entwicklungen Irrwege sind. Das Buch gliedert sich in zwei Hauptteile. Im ersten Teil wird der Begriff der praktischen Fähigkeit bzw. der Handlungs- und Willensfreiheit analysiert. Unter welchen Bedingungen kann (...) ein Akteur etwas anderes als das tun, was er faktisch tut, bzw. unter welchen Bedingungen ist ein Akteur frei, anders zu handeln? In der philosophischen Diskussion dieser Frage ist traditionell ein zentraler Aspekt, ob zu diesen Bedingungen auch Indetermination zählt. Philosophen, die die Freiheit, anders zu handeln, für kompatibel mit dem Determinismus halten, haben oftmals eine konditionale Analyse von Freiheit/Können vertreten (Augustin, Hobbes, Hume, Moore, Tugendhat). Gegen diese Analyse sind jedoch zahlreiche Einwände erhoben worden, die von den meisten Philosophen, auch von Kompatibilisten, für triftig gehalten werden. Ich versuche im ersten Teil, die Konditionalanalyse gegen die erhobenen Einwände zu verteidigen. Im zweiten Teil der Arbeit geht es um die Frage, unter welchen Bedingungen Akteure moralisch verantwortlich gemacht werden können. Diese Frage ist mit der Frage nach der Fähigkeit, anders zu handeln, dadurch verbunden, dass einer lange unbestrittenen Annahme zufolge jemand nur dann moralisch verantwortlich sein kann, wenn er anders hat handeln können. Diese Annahme ist in neuerer Zeit – im Gefolge Harry Frankfurts – angezweifelt worden. Ich versuche zu zeigen, dass die Annahme dennoch richtig ist. Ich entwickle eine an Überlegungen Peter Strawsons angelehnte Analyse von moralischer Verantwortung, der zufolge ein Akteur moralisch verantwortlich für ein Ereignis ist, wenn er in einer kausalen Beziehung zu ihm steht, welche Rückschlüsse auf die moralische Qualität seines Willens ermöglicht. Durch eine Analyse der Adäquatheitsbedingungen moralischer Beurteilung von Akteuren versuche ich zu zeigen, dass die relevanten Kausalbeziehungen dann bestehen, wenn eine bestimmte Konditionalanalyse die Fähigkeit zuschreibt, anders zu handeln. Alternative Möglichkeiten im Sinne dieser Analyse sind notwendig und hinreichend für moralische Verantwortung. (shrink)

Originally published in 1990, this book centres on a certain way of surveying a variety of theories of language, and on outlining a new proposal of meaning within the framework set by the survey. One of the key features of both survey and proposal is the insistence on the need to locate theories of language within a large framework that includes questions about the nature of thought and about general ontological questions as well. The book deals in an interconnected way (...) with both very general and specific issues. At one end of this spectrum there are discussions of the contrast between realist and nominalist ontologies, while at the other are analyses of specific lexical items of English. (shrink)

In this book, Julius M. Moravcsik disputes that a natural language is not and should not be represented as a formal language. The book criticizes current philosophy of language as having an altered focus without adjusting the needed conceptual tools. It develops a new theory of lexical meaning, a new conception of cognition-humans not as information processing creatures but as primarily explanation and understanding seeking creatures-with information processing as a secondary, derivative activity. In conclusion, based on the theories of (...) lexical meaning and cognition, this work sketches an argument showing that the human understanding of human understanding must always remain just partial.

"Only a wayfarer born under unruly stars would attempt to put into practice in our epoch of proliferating knowledge the Heraclitean dictum that `men who love wisdom must be inquirers into very many things indeed.'" Thus begins this remarkable interdisciplinary study of time by a master of the subject. And while developing a theory of "time as conflict," J. T. Fraser does offer "many things indeed"--an enormous range of ideas about matter, life, death, evolution, and value.

Aristotle did not see a sharp contrast between the psychological and the physical. He viewed the physical as just the natural, and treats the psychological as part of the physical. This essay attempts to explain why this is so, and presents observations about Aristotle’s framework. It explores the relation of hylomorphism to functionalism, and argues against funtionalist interpretations of Aristotle due to the belief that Aristotle was confronting a different set of concerns and issues.

Morality is often thought of as non-rational or sub-rational. In Moral Notions, first published in 1967, Julius Kovesi argues that the rationality of morality is built into the way we construct moral concepts. In showing this he also resolves the old Humean conundrum of the relation between 'facts' and 'values'. And he puts forward a method of reasoning that might make 'applied ethics' (at present largely a hodge-podge of opinions) into a constructive discipline. Kovesi's general theory of concepts - (...) important in its own right - is indebted to his interpretation of Plato, and his three papers on Plato, first published here, explain this debt. This new edition of Moral Notions also includes a foreward by Philippa Foot, a biography of the author, and a substantial afterword in which the editors, Robert Ewin and Alan Tapper, explain the signficance of Kovesi's work.

In this comment I respond to the criticisms put forth by Muller et al. It is my assessment that the authors’ make useful suggestions for future analyses. However, their conclusion regarding the invalidity of my results are based on a misconception of the goals and data used in my article.
