This article probes the relationship among constitutionalism, extra-legal prerogative power, and citizen judgment. While much has been written about the nature of Lockean prerogative, and while his theory serves as a direct inspiration for contemporary "normative extra-legalists," key participants in the debate over emergency powers, less attention has been paid to how the people judge prerogative. Attention to this issue is useful because an examination of the process of political judgment of extra-legalism in Locke leads to a complication of the (...) current extra-legalist vision of democratic mechanisms of accountability. The author argues that the extra-legal approach is right to consider the role of democratic publics in potentially constraining the exercise of emergency powers but wrong to formulate that role as one extra-constitutional power checking another extra-constitutional power. The author situates both prerogative power and citizen judgment of it at the threshold of the constitutional order. (shrink)

In the dyadic and triadic sharing of emotions, intentions, and behaviors in families, interactive synchrony is important to the early life experiences that contribute to the development of cultural cognition. This synchrony likely depends on neurobiological circuits, currently under study with brain imaging, that involve attention, stress response, and memory.

The main question that Firestone & Scholl (F&S) pose is whether “what and how we see is functionally independent from what and how we think, know, desire, act, and so forth” (sect. 2, para. 1). We synthesize a collection of concerns from an interdisciplinary set of coauthors regarding F&S's assumptions and appeals to intuition, resulting in their treatment of visual perception as context-free.

Face perception is a highly conserved process that directs our attention from infancy and is supported by specialized neural circuitry. Oxytocin can increase accuracy and detection of emotional faces, but these effects are mediated by valence, individual differences, and context. We investigated the temporal dynamics of oxytocin’s influence on the neural substrates of face perception using event related potentials (ERP). In a double blind, placebo controlled within-subject design, 21 healthy male adults inhaled oxytocin or placebo and underwent ERP imaging during (...) two face processing tasks. Experiment 1 investigated effects of oxytocin on neural correlates of fearful versus neutral facial expressions, and Experiment 2 manipulated point-of-gaze to neutral faces. In Experiment 1, we found that oxytocin reduced N170 latency to fearful faces. In Experiment 2, N170 latency was decreased when participant gaze was directed to the eyes of neutral faces; however, there were no oxytocin-associated effects in response to different facial features. Findings suggest oxytocin modulates early stages of social perception for socially complex information such as emotional faces relative to neutral. These results are consistent with models suggesting oxytocin impacts the salience of socially informative cues during processing, which leads to downstream effects in behavior. Future work should examine how oxytocin affects neural processes underlying basic components of social behavior (such as, face perception) while varying emotional expression of stimuli or comparing different characteristics of participants (e.g., gender, personality traits).

The Patient Self Determination Act of 1991 brought much needed attention to the importance of advance care planning and surrogate decision-making. The purpose of this law is to ensure that a patient’s preferences for medical care are recognized and promoted, even if the patient loses decision-making capacity. In general, patients are presumed to have DMC. A patient’s DMC may come under question when distortions in thinking and understanding due to illness, delirium, depression or other psychiatric symptoms are identified or suspected. (...) Physicians and other healthcare professionals working in hospital settings where medical illness is frequently comorbid with depression, adjustment disorders, demoralization and suicidal ideation, can expect to encounter ethical tension when medically sick patients who are also depressed or suicidal request do not resuscitate orders.

Most models of generational succession in sexually reproducing populations necessarily move back and forth between genic and genotypic spaces. We show that transitions between and within these spaces are usually hidden by unstated assumptions about processes in these spaces. We also examine a widely endorsed claim regarding the mathematical equivalence of kin-, group-, individual-, and allelic-selection models made by Lee Dugatkin and Kern Reeve. We show that the claimed mathematical equivalence of the models does not hold.

Plato, Aristotle, Kant, Brentano, Moore, and Chisholm have suggested marks or criteria of intrinsic goodness. I distinguish among eight of these. I focus in this paper on four: (a) unimprovability, (b) unqualifiedness, (c) dependence upon intrinsic natures, and (d) incorruptibility. I try to show that each of these is problematic in some way. I also try to show that they are not equivalent – they point toward distinct conceptions of intrinsic goodness. In the end it appears that none of them (...) is fully satisfactory. Insofar as none of these succeeds, a fundamental problem remains for those who make use of the concept of intrinsic value. Precisely what do we have in mind when we say that some sort of value is intrinsic? (shrink)

Vasubandhu is perhaps the most influential figure in the history of Buddhist philosophy, yet the very breadth of his contribution across many schools and traditions has led to a fragmentation of his works, as interpreters have tended to read them through the lens of narrow scholastic perspectives, finding little continuity or coherence. Some modern scholars, doubtful that anyone could have held such varied views, have gone so far as to divide Vasubandhu himself into two distinct philosophers, with two different and (...) irreconcilable views. In his recent book, Paving the Great Way: Vasubandhu’s Unifying Buddhist Philosophy, Jonathan Gold offers for the first time a unified picture of Vasubandhu, extracting the driving... (shrink)

Psychological construction constitutes a different paradigm for the scientific study of emotion when compared to the current paradigm that is inspired by faculty psychology. This new paradigm is more consistent with the post-Darwinian conceptual framework in biology that includes a focus on (a) population thinking (vs. typologies), (b) domain-general core systems (vs. physical essences), and (c) constructive analysis (vs. reductionism). Three psychological construction approaches (the OCC model, the iterative reprocessing model, and the conceptual act theory) are discussed with respect to (...) these ideas. (shrink)

According to the conceptual act theory, emotions emerge when physical sensations in the self and physical actions in others are meaningfully linked to situations during a process that can be called both cognitive and perceptual (creating emotional experiences, and emotion perceptions, respectively). There are key four hypotheses: (a) an emotion (like anger) is a conceptual category, populated with instances that are tailored to the environment; (b) each instance of emotion is constructed within the brain’s functional architecture of domain-general core systems; (...) (c) the workings of each system must be holistically understood within the momentary state of the brain, the body, and the surrounding context; (d) being emergent states, emotional episodes have functional features that physical states, alone, do not have. Similarities and differences to other theoretical approaches to emotion are discussed. (shrink)

Critiquer la Déclaration universelle des droits de l’homme du 10 décembre 1948 paraît relever de la provocation ou de l’inconscience. Ses contempteurs, qu’il s’agisse des marxistes ou des conservateurs, se sont déconsidérés. Nonobstant, c’est avec force courage que Hayek s’est attelé dès 1966 à une critique en règle de cette déclaration “constructiviste” dont l’objectif impossible était de fusionner les droits de la tradition libérale avec ceux de la conception marxiste. Le Prix Nobel démontre que les nouveaux droits ainsi proclamés ne (...) peuvent être traduits dans des lois contraignantes sans détruire incontinent l’ordre de liberté auquel tendent les droits “traditionnels” : la Déclaration constitue l’un de ces instruments qui oeuvrent à la dévalorisation du Droit et partant à la destruction de la Liberté. C’est par son prestige et par l’ignorance de ceux qui l’ont exploité que ce texte a pu prospérer. Son seul mérite est de mériter l’oubli.It might seem provocative or inconsistent to criticize the Universal Declaration of Human Rights of December 10, 1948. Its detractors, whether they be Marxists or Conservatives have fallen into discredit. Notwithstanding, Hayek has courageously tried to criticize this “constructivist” piece whose impossible goal was to unite rights in the liberal tradition with those pertaining to the Marxist conception. Hayek shows that the new rights which are proclaimed in this fashion cannot be translated into juridical constraints without destroying forthwith the liberal order cherished by “traditional” rights: the Universal Declaration of Human Rights is one of the tools which enhances the depreciation of Law and, by the way, the annihilation of Freedom. This text has flourished thanks to its prestige and to the ignorance of those who have employed it. Its unique merit is to deserve oblivion. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:American Journal of Philology 124.2 (2003) 313-316 [Access article in PDF] Erich S. Gruen. Diaspora: Jews amidst Greeks and Romans. Cambridge, Mass: Harvard University Press, 2002. xiv + 386 pp. Cloth, $39.95. This survey of Jewish culture outside of Palestine, that is, the diaspora, during the period from Alexander the Great to Nero challenges the sensus communisin point after point through a fresh, nuanced rereading of the primary texts. (...) Gruen's greatest contribution is that he sees the events, particularly alleged anti-Semitism, of Jewish history and the literature produced by Hellenistic Jews against the backdrop of the events of contemporary non-Jewish history and culture.An excellent example of Gruen's extremely sensible and balanced evaluation of primary sources is to be seen in his examination of the Jewish community of Rome. In particular, he focuses on the periodic expulsions of the Jews from Rome in the late Republic and early Principate. Gruen rightly calls attention to the fact that the expulsion in 139 B.C.E.included others, namely Chaldeans and worshippers of Sabazius, besides Jews. Even more important, he correctly concludes that the expulsion did not discourage Jews from dwelling in the city, since they continued to be there in sizable numbers by the age of Cicero, as we know from Pro Flacco. Gruen appositely notes that a mere two decades earlier, in 161 B.C.E., the Senate authorized the expulsion of philosophers and rhetors, but that in 155 B.C.E.Greek philosophers were again in Rome. Similarly, many sumptuary laws were repeatedly passed (hence unenforced), which were plainly unenforceable. In short, the Jews continued to feel comfortable in Rome. [End Page 313]As to the pogrom in Alexandria in the year 38 C.E., Gruen, through a careful reading of Philo, convincingly concludes that the deep-rooted hostility of which he speaks applies primarily to rank and file, lower-class Egyptians rather than to Greeks. And yet, we may remark, the fact that in the wake of this pogrom a Greek embassy went to the Emperor in Rome would seem to indicate that the Greeks had formed an unholy alliance with the Egyptians and that the event that triggered the uprising was the triumphal visit of Agrippa I, who had just been crowned king of Judea in Rome, and the charge of dual loyalty that his visit brought to the surface. But, as Gruen notes, the Jewish community in Alexandria had fared well politically and economically, except for this incident, which was clearly exceptional.Another excellent example of fresh insight is Gruen's analysis of the background of the documents preserved by Josephus that consist of Roman responses to Jewish appeals for protection of their rights, which were endangered by the actions of Greek cities in Asia Minor. Other scholars have viewed these documents as evidence that the Jews were persecuted by local Greek officials and were regularly rescued by Roman intervention. Gruen has convincingly shown that most of the documents belong to a very brief period of time when Rome was in the midst of a seemingly endless series of civil wars and realignments and that the circumstances were exceptional rather than representative. On the contrary, the documents themselves demonstrate that the Jewish communities were flourishing during this period.One factor to which Gruen does give due consideration but dismisses is the Roman resentment of proselytism by Jews. He notes Tacitus' statement (Histories5.5.2) that proselytes abandoned their ancestral religions, scorned their native gods, deserted their nation, and do not care for parents, children, or siblings. Tacitus, he says, here excoriates apostates but suggests no Jewish menace. Tacitus' language, however, is strong even for a rhetorician and does suggest a Jewish menace for the Roman nation, of which the native religion was an integral part. Horace, to be sure a satirist, likewise alludes to the Jews' zeal in seeking converts as if it were proverbial: "We are more numerous, and like the Jews we shall force you to defer [concedere, yield] to our throng" (Satires1.4.142-43). Gruen says that... (shrink)

In a recent note, D. Braund has challenged my identification of the Pollio at whose home in Rome Herod's sons Alexander and Aristobulus stayed in 22 b.c. as Gaius Asinius Pollio, the famous consul of 40 b.c., who was a close friend of Julius Caesar and to whom Virgil dedicated his Fourth Eclogue. Braund's argument rests upon five grounds. If this Pollio were a man of the stature of Asinius Pollio, we would expect Josephus to make his identity clear and (...) not to describe him solely as one of Herod's most devoted friends. Josephus' reference to Pollio here is different from the definite references to Asinius Pollio elsewhere in Josephus, where he is referred to as Asinius or Gaius Asinius Pollio. In the latter passage his name is spelled Πωλίωνος, whereas the name of the host of Herod's sons is spelled Πολλίωνος. When Herod sent two other sons to Rome, they stayed ‘with a certain Jew’, and hence it seems likely that the two other sons likewise stayed with a Jew. Asinius' role in the elevation by the Roman Senate of Herod to the kingship of Judaea was no greater than that of any other magistrate. (shrink)

In 1982, Feldman and Ballard published "Connectionist models and their properties" in Cognitive Science , helping to focus attention on a family of similarly inspired research strategies just then under way, by giving the family a name: "connectionism." Now, seven years later, the connectionist nation has swelled to include such subfamilies as "PDP" and "neural net models." Since the ideological foes of connectionism are keen to wipe it out in one fell swoop aimed at its "essence", it is worth (...) noting the diversity of not only the models but also the aspirations of the modelers. There is no good reason to suppose that they all pledge allegiance to any one principle.. (shrink)

Linguists intuitions about language change can be captured by adynamical systems model derived from the dynamics of language acquisition.Rather than having to posit a separate model for diachronic change, as hassometimes been done by drawing on assumptions from population biology (cf.Cavalli-Sforza and Feldman, 1973; 1981; Kroch, 1990), this new modeldispenses with these independent assumptions by showing how the behavior ofindividual language learners leads to emergent, global populationcharacteristics of linguistic communities over several generations. As thesimplest case, we formalize the example (...) of two grammars and show that eventhis situation leads directly to a nonlinear (quadratic) dynamical system.We study this one parameter model in a variety of situations for differentkinds of acquisition algorithms and maturational times, showing howdifferent learning theories can have very different evolutionaryconsequences. This allows us to formulate an evolutionary criterion for theadequacy of grammatical and learning theories. An application of thecomputational model to the historical loss of Verb Second from Old French toModern French is described showing how otherwise adequate grammaticaltheories might fail the evolutionary criterion.

The so-called internalism/externalism debate is of interest in epistemology since it addresses one of the most fundamental questions in the discipline: what is the basic nature of epistemic justification? What has been called epistemic internalism holds, as the label suggests, that all the relevant factors that determine positive epistemic status of a belief must be “internal”. A common way that the “internal” is understood is those things that are, or easily can be, available to the agent’s conscious awareness. However, there (...) is another, and increasingly popular, way of spelling out the epistemically “internal”. A view advocated by Feldman and Conee which they regard as a kind of epistemic internalism, called ‘Mentalism’, holds that epistemic justification strongly supervenes upon the mental. In this paper I will show that even many of those who claim to deny an awareness requirement implicitly appeal to it to motivate their accounts of justification. By considering the arguments for ‘Mentalism’ I will show that, unless an awareness requirement is presupposed, the cases that such arguments appeal to are of no intuitive force. Therefore, insofar as one wants to be an internalist about epistemic justification, one needs to motivate, articulate, and defend an access/awareness condition. Epistemic Internalism, properly construed, ought to stress the epistemic significance of consciousness and the first person perspective. (shrink)

A new theory of how the brain constructs emotions that could revolutionize psychology, health care, law enforcement, and our understanding of the human mind Emotions feel automatic, like uncontrollable reactions to things we think and experience. Scientists have long supported this assumption by claiming that emotions are hardwired in the body or the brain. Today, however, the science of emotion is in the midst of a revolution on par with the discovery of relativity in physics and natural selection in biology--and (...) this paradigm shift has far-reaching implications for us all. Leading the charge is psychologist and neuroscientist Lisa Feldman Barrett, whose theory of emotion is driving a deeper understanding of the mind and brain, and shedding new light on what it means to be human. Her research overturns the widely held belief that emotions are housed in different parts of the brain and are universally expressed and recognized. Instead, she has shown that emotion is constructed in the moment, by core systems that interact across the whole brain, aided by a lifetime of learning. This new theory means that you play a much greater role in your emotional life than you ever thought. Its repercussions are already shaking the foundations not only of psychology but also of medicine, the legal system, child-rearing, meditation, and even airport security. Why do emotions feel automatic? Does rational thought really control emotion? How does emotion affect disease? How can you make your children more emotionally intelligent? How Emotions Are Made answers these questions and many more, revealing the latest research and intriguing practical applications of the new science of emotion, mind, and brain. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:NAMING GOD: MOSES MAIMONIDES AND THOMAS AQUINAS NEIL A. 8TUBBENS The Methodist Ohurch Barnsley Oircuit, South Yorkshire MOSES MAIMONIDES (1135-U04) and Thomas Aquinas (c. U~5-1274), two of the greatest theologians of the Jewish and Christian faiths, had much in oommon.1 Like other Ohristian.writers, Aquinas made several criticisms of Maimonides' views on divine predication. In this article l will discuss these criticisms and evaluate them by means of a detailed (...) e:iq>0sition of Maimonides' position. I will ithen offer an account of Aquinas's justification of analogical predication and make some suggestions ais to the :role of causality in naming God. 1. Introduetion Moses Maimonides was the middle-man in the interaction of the three monotheistic faiths with Aristotelian philosophy. He was a great admirer of the ancient philosopher, claiming that Aristotle':s intellect reached the highest perfection attainable hy humanity-e:reept by the prophets and they WeTe divinely inspired. Maimonides :firrst work, the short Treatise on Logic, clewly reflects ihis own interest in logic and language and shows the influence of Afistotle mediated through the Ambs.2 It was The Guide or the Perplexed, his last major work, that introduced the mostly Christian West to the thought of the Islamic philosophers Alf.arabi, Avicenna, and 1 On some matters Aquinas refers to Maimonides as a:ii. authority, e.g., De potentia, q.7, a.4, c; Summa theologiae (ST), I, q.68, a.2 ad 1. 2 Treatise on Logic, translated by I. Efros, Proceedmgs of the American Academy for Jewish Research 8 (1938): 1-65. 230 NEIL A. STUBBENS Avermes.3 The Guide, however, is not so much a philosophical work as a iphilosoprucal interpretation of the Bible. Like the thinkers of the Christian monastic anrd later cathedral schools of the eleventh and rbwelfth centuries, Maimonides began his reflections with the wo;vds of Scripture. Soon after its publication in 1190, two Hebrew triansla:tions of the Guide were produced from,the original Arabic by Samuel Ibn Tibbon and Jehudah al-Harizi; Aquinas wo:rked with_ a Latin translation of the Harizi version.4 Feldman has complained that some of the scholastics misinterpreted Maimonides, foisting upon him views which were clearly not his own. According :to Feldman, Giles of Rome.(c. 1247-1316), in his ErrofJ'es Philosophorum, misformulates Maimonides' theory of negative ·attributes and suggests that he employs attributes ".by wa.y of causality." 5 Duns Scotus (c. 1264-1308) cites Maimonides and Avicenna ws ·advocating attributes of efficient causality. Henry of Ghent (d. 1293), in his Summa theologiae, moorrrectly construes actions as relations : "Indeed", writes Feldman, "he characterises them as ruttributes 'hy way of causality.'" Aquinas's translators and interp:veters come in d)or as much criticism from Feldman as :Aquinas himself, e.g., R. Garrigou-Lagrange,6 M. Penido,7 and R. Mulligan:8 all mistakenly say that a.ooording to Maimonides "God is good" means "God is the ca;use of good things.'' a See S. Pines, "Translator's Introduction: the Philosophic Sources of The Guide of the Perplwed," in The Guide of the Perplewed, trans. S. Pines (Chicago, 1963). 4 The chapters of the Harizi and Latin versions are enumerated one less than those of the Ibn Tibbon version. I shall use the latter scheme as is common practice. 5.S.

MAIMONIDES AND AQUINAS 2. Aquinas's Criticism of Maimonides There are five points of disagreement between Aquinas and Maimonides. First, Aquinas argues that if expressions such as " God is wise " and " God is angry " are used to indicate only a likeness of effect, i.e., we say " God is wise" or " God is angry " because in his effoots he acts lilre a wise or angry person, there would he no difference in the...

Is the United States "the land of equal opportunity" or is the playing field tilted in favor of those whose parents are wealthy, well educated, and white? If family background is important in getting ahead, why? And if the processes that transmit economic status from parent to child are unfair, could public policy address the problem? Unequal Chances provides new answers to these questions by leading economists, sociologists, biologists, behavioral geneticists, and philosophers.New estimates show that intergenerational inequality in the United (...) States is far greater than was previously thought. Moreover, while the inheritance of wealth and the better schooling typically enjoyed by the children of the well-to-do contribute to this process, these two standard explanations fail to explain the extent of intergenerational status transmission. The genetic inheritance of IQ is even less important. Instead, parent-offspring similarities in personality and behavior may play an important role. Race contributes to the process, and the intergenerational mobility patterns of African Americans and European Americans differ substantially.Following the editors' introduction are chapters by Greg Duncan, Ariel Kalil, Susan E.

Hume after arguing for the compatibility of liberty and necessity, a view now known as soft determinism or compatibilism , noted that it is not ‘possible to explain distinctly, how the Deity can be the mediate cause of the actions of sin and moral turpitude’. It seems that Hume is correct if the explanation must show specifically why an omnipotent and omnibenevolent deity must permit certain actions that to human reason seem to be unnecessary evils. On the other hand if (...) such specifity is not required, the soft determinist who also happens to be a theist can argue that it is possible that the actual world is the best of all possible worlds even though the reason for any specific apparent evil cannot be known. If seemingly evil choices are free in the soft determinist's sense but determined by an omnipotent and omniscient deity, then either that deity is not omnibenevolent or that deity has determined the world to have the maximum possible goodness through including seemingly evil choices in the scheme of things. Consequently if, as the traditional theist believes, the creator is omnibenevolent as well as omnipotent and omniscient, the occurrence of seemingly evil choices are necessary for maximizing the goodness of the whole.

Upshot: My answer focuses on two issues raised by the commentaries that it is essential to clarify in order to understand what radical neurophenomenology implies: Does radical neurophenomenology means stopping doing science? Does radical neurophenomenology require an intersubjective agreement on a method for investigating lived experience?

The preparation of layers of amorphous Se by plasma-enhanced CVD using the hydride H2Se as precursor gas is described. Information concerning the structure of the films was obtained from Raman spectroscopy. The spectra of amorphous Se indicated that the dominant molecular structure is the eight-membered ring and/or a chain with Se8 molecular fragments. This material exhibited reversible photodarkening when illuminated at 77 K. In order to explain this phenomenon, we propose a mechanism which takes into account the role of the (...) lone-pair electron orbitals of Se in their contribution to structural ordering. Illumination can cause a distortion in the normal bonding direction between nearest-neighbour Se atoms and induce in this way intrinsic defect states located at the band edges. In the photo-darkened state, optical transition will occur between these defect states. (shrink)
