I compare Frith and colleagues’ influential comparator account of how the sense of agency is elicited to the multifactorial weighting model advocated by Synofzik and colleagues. I defend the comparator model from the common objection that the actual sensory consequences of action are not needed to elicit the sense of agency. I examine the comparator model’s ability to explain the performance of healthy subjects and those suffering from delusions of alien control on various self-attribution tasks. It transpires that the comparator (...) model needs case-by-case adjustment to deal with problematic data. In response to this, the multifactorial weighting model of Synofzik and colleagues is introduced. Although this model is incomplete, it is more naturally constrained by the cases that are problematic for the comparator model. However, this model may be untestable. I conclude that currently the comparator model approach has stronger support than the multifactorial weighting model approach. (shrink)

Scientific cognitivism is the idea that nature must be aesthetically appreciated in light of scientific information about it. I defend Carlson's traditional formulation of scientific cognitivism from some recent criticisms. However, I also argue that if we employ this formulation it is difficult to uphold two claims that Carlson makes about scientific cognitivism: (i) it is the correct analysis of the notion of appropriate aesthetic appreciation of nature, and (ii) it justifies the idea that nature, seen aright, is always beautiful (...) (that is, positive aesthetics about nature). I attempt to find a revised formulation of scientific cognitivism that can support both of these claims. I argue that to do this we must rethink the notion of positive aesthetics and its place in our theorizing about the appropriate aesthetic appreciation of nature. Specifically, I propose that positive aesthetics be made ‘internal’ to the theory of appropriate aesthetic appreciation, in the sense that this theory determines the correct scientific categories for appreciating a natural object, in part, in virtue of a ‘beauty-making’ criterion. I argue that this sort of formulation of scientific cognitivism can support both of Carlson's claims and does not compromise the objectivist scruples that motivate the view. (shrink)

Much recent discussion in the aesthetics of nature has focused on Scientific cognitivism, the view that in order to engage in a deep and appropriate aesthetic appreciation of nature, one must possess certain kinds of scientific knowledge. The most pressing difficulty faced by this view is an apparent tension between the very notion of aesthetic appreciation and the nature of scientific knowledge. In this essay, I describe this difficulty, trace some of its roots and argue that attempts to dismiss it (...) fail. I then develop a response to the problem, drawing on the notion of the theory-ladenness of observation. I conclude by considering the relationship between this response and one common approach to the problem, the appeal to expressive qualities in nature. (shrink)

Socrates' dream puts in generalized form the difficulty that plato saw in the mathematician's procedure of hypothesis, I.E., Of positing undemonstrated first principles ("prota") or elements ("stoicheia") as starting-Points of demonstration. If the elements are unknown, How can what is constructed from them be known?--A difficulty to which plato had earlier called attention in the 'republic' (510cd, 533cd.) this interpretation accords with the mathematical setting and personages of the dialogue, And explains why the explicit refutation of theaetetus' third proposal, That (...) knowledge be defined as true belief accompanied by a logos, Is so perfunctory and unconvincing. Furthermore, The dilemma thus brought to light is reflected in 'posterior analytics' (book i, Chap. 3), Which was presumably written during aristotle's residence in the academy in association with plato and the other mathematicians gathered around him.

Professions have traditionally treated advocacy as a collective duty, best assigned to professional associations to perform. In North American nursing, advocacy for issues affecting identifiable patients is assigned instead to their nurses. We argue that nursing associations’ withdrawal from advocacy for patient care issues is detrimental to nurses and patients alike. Most nurses work in large institutions whose internal policies they cannot influence. When these create obstacles to good care, the inability of nurses to affect change can result in avoidable (...) distress for them and for their patients. We illustrate this point with a case study: the circumstances of the death of Michael Joseph LeBlanc, an inmate at Kingston Penitentiary Regional Hospital (Ontario). We conclude that patients and their nurses will suffer unnecessarily unless or until nursing associations cease to burden individual nurses with the responsibility for patient advocacy. (shrink)

Die unter dem Titel "Metaphysik "überlieferte kleine Abhandlung des Aristotelesschülers Theophrast enthält eine ebenso kompakte wie kritische Rekonstruktion ungelöster systematischer Grundlagenprobleme der klassischen griechischen Philosophie, angefangen bei den Vorsokratikern über Platon und die Akademie bis hin zu Aristoteles. Es geht vornehmlich um fundamentale Aporien der Ontologie und der Naturphilosophie, wie die Frage nach der Interdependenz ideeller Prinzipien und wahrnehmbarer Phänomene oder die Plausibilität der Teleologie als methodisches Prinzip der Naturerklärung. Theophrast analysiert und bewertet die geläufigen konkurrierenden Lösungsvorschläge und zeigt ihre (...) Defizite unerbittlich auf: ein Stück synoptischer Metaphysikkritik, das an zeitgenössische Typen der Dekonstruktion erinnert. Der Text hat seinen Wert als Dokument für den Übergang von einer konstruktiven zu einer eher skeptischen, in Teilen sogar destruktiven Phase der klassischen griechischen Tradition und zeigt exemplarisch, vor allem am Verhältnis der theophrastschen zur aristotelischen "Metaphysik", wie sehr die jeweiligen philosophischen Positionen sich in Abhängigkeit von der jeweiligen Rezeption vorgängiger Rezeptionsprozesse entwickelten. Die erstmals mit einer deutschen Übersetzung erscheinende kritische Edition dieses philosophiehistorischen Schlüsseltextes hat das Ziel, diese Bedeutung des bislang zu wenig beachteten Dokuments aus der Schule des Aristoteles sichtbar zu machen.

Numerous searches have failed to identify a single co-occurrence of total blindness and schizophrenia. Evidence that blindness causes loss of certain NMDA-receptor functions is balanced by reports of compensatory gains. Connections between visual and anterior cingulate NMDA-receptor systems may help to explain how blindness could protect against schizophrenia.

The liver was used widely in early studies of polarised transport but has been largely overlooked in recent years, mostly because of the development of epithelial cell lines which provide more tractable experimental systems. The majority of membrane proteins and lipids reach the hepatocyte apical membrane by transcytosis and it remains unclear whether there is a direct route for apical targeting, although the pathways present have yet to be fully characterised. The recent development of systems that allow hepatocyte transport processes (...) to be studied in culture and the observation that transcytosis can be significantly stimulated under physiological conditions suggest that hepatocytes have a role to play in future studies of polarised transport. This review discusses the known features of polarised membrane traffic in hepatocytes and contrasts them with the characteristics of vesicular transport in other epithelial cell types. (shrink)

Are there no new ideas to be invented? Are today's ideas really just borrowed from previous times? Postmodernism says this is so, and it's one of the hottest philosophies of today. The book provides an indispensable guide to this often-demanding terrain for readers encountering theories of postmodernism for the first time and places the subject in a broad context. It introduces a wide range of ideas, thinkers, and views yet maintains the readers' focus by linking theory with concrete examples from (...) both "high" and "popular" culture. After completing Teach Yourself Postmodernism , readers will never look at their world the same way again. (shrink)

There is at this point no shortage of testimonials regarding the practice of philosophy for children. In addition, there have been a number of studies which give further support to the claim that philosophy for children is a valuable classroom practice. The idea that pre-college instruction in philosophy is beneficial is no longer in doubt, nor is there a significant lack of materials for use in philosophy for children programs. From Lewis Carroll to Matthew Lipman authors constructed texts that go (...) far in engaging children's philosophical inclinations. If there is any weakness in the practice of philosophy for children it is usually found in the individual classroom. (shrink)

Infinity and the Brain proposes a logical and scientific way to resolve the paradox of mind and matter -- by explaining how the perception of a finite image is dependent upon the contrasting infinitude of God. The theory holds that awareness is equal to a tension between existence and nonexistence, such that the self is illuminated to itself (becomes conscious) to the exact measure that it anticipates the infinitude of its own nonexistence. This "anticipation" is actually a "tendency toward" a (...) loss of structure in accordance with the second law of thermodynamics, a process that is restrained by effort and the consequent wholesness of an image. An understanding of how effort is linked to an image and how both are dependent upon neural systems inseparable from "infinity anticipation" sets the stage for a new worldview -- in which mind is seen as dependent upon the immanence of an infinite God. And because "mind" can be defined by the presence of an image which intrinsically restrains disorder, we see by extrapolation that the entire universe must be fundamentally personal, not objective as currently viewed by modern science.

An evolutionary model of human behavior should privilege emotions: essential, phylogenetically ancient behaviors that learning and decision making only subserve. Infants and non-mammals lack advanced cognitive powers but still survive. Decision making is only a means to emotional ends, which organize and prioritize behavior. The emotion of pride/shame, or dominance striving, bridges the social and biological sciences via internalization of cultural norms. (Published Online April 27 2007).

The Internet and social media have opened niches for political exploitation of human dispositions to hyper-alarmed states that amplify perceived threats relative to their objective probabilities of occurrence. Researchers should aim to observe the dynamic “ramping up” of security threat mechanisms under controlled experimental conditions. Such research necessarily begins from a clear model of standard baseline states, and should involve adding treatments to established experimental protocols developed by experimental economists. We review these protocols, which allow for joint estimation of risk (...) preferences and subjective beliefs about probabilities and their distributions. Results we have obtained on such estimates, from populations in various countries, are gathered for comparison. Most people show moderate risk aversion in non-alarmed states. We also find universal heterogeneity in risk preference structures, with substantial sub-samples weighting probabilities in such a way as to display “probability pessimism”, while others make risky choices in accordance with expected utility theory.

Fake news is a worrying phenomenon which is growing increasingly widespread, partly because of the ease with which it is disseminated online. Combating the spread of fake news requires a clear understanding of the nature of fake news. However, the use of the term in everyday language is heterogenous and has no fixed meaning. Despite increasing philosophical attention to the topic, there is no consensus on the correct definition of “fake news” within philosophy either. This paper aims to bring clarity (...) to the philosophical debate of fake news in two ways: Firstly, by providing an overview of existing philosophical definitions and secondly, by developing a new account of fake news. This paper will identify where there is agreement within the philosophical debate of definitions of “fake news” and isolate four key questions on which there is genuine disagreement. These concern the intentionality underlying fake news, its truth value, the question of whether fake news needs to reach a minimum audience, and the question of whether an account of fake news needs to be dynamic. By answering these four questions, I provide a novel account of defining “fake news”. This new definition hinges upon the fact that fake news has the function of being deliberately misleading about its own status as news. (shrink)

Gottfried Wilhelm Leibniz was one of the central figures of seventeenth-century philosophy, and a huge intellectual figure in his age. This book from Glenn A. Hartz is an advanced study of Leibniz's metaphysics. Hartz analyzes a very complicated topic, widely discussed in contemporary commentaries on Leibniz, namely the question of whether Leibniz was a metaphysical idealist, realist, or whether he tried to reconcile both trends in his mature philosophy. Because Leibniz is notoriously unclear about this, much has been written (...) on the subject. In recent years, the debate has centered on whether it is possible to maintain compatibility between the two trends. In this controversial book, Hartz demonstrates that it is not possible to maintain compatibility of idealist and realist views - they must be understood as completely separate theories. As the first major work on realism in Leibniz's metaphysics, this key text will interest international Leibniz scholars, as well as students at the graduate level. (shrink)
