In the past two decades, reinforcement learning has become a popular framework for understanding brain function. A key component of RL models, prediction error, has been associated with neural signals throughout the brain, including subcortical nuclei, primary sensory cortices, and prefrontal cortex. Depending on the location in which activity is observed, the functional interpretation of prediction error may change: Prediction errors may reflect a discrepancy in the anticipated and actual value of reward, a signal indicating the salience or novelty of (...) a stimulus, and many other interpretations. Anterior cingulate cortex has long been recognized as a region involved in processing behavioral error, and recent computational models of the region have expanded this interpretation to include a more general role for the region in predicting likely events, broadly construed, and signaling deviations between expected and observed events. Ongoing modeling work investigating the interaction between ACC and additional regions involved in cognitive control suggests an even broader role for cingulate in computing a hierarchically structured surprise signal critical for learning models of the environment. The result is a predictive coding model of the frontal lobes, suggesting that predictive coding may be a unifying computational principle across the neocortex. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 147 The Godly Image: Christ and Salvation in Catholic Thought from Anselm to Aquinas. By ROMANUS CESSARIO, O.P. Studies in historical theology. v. 6. Petersham, Mass.: St. Bede's Publications, 1990. Pp. xxiv + 214. $14.95 (paper). The Godly Image presents a retouched version of the author's dissertation, first published in 1982 as Christian Satisfaction in Aquinas: Towards a Personalist Understanding (Washington, DC: University Press of America). Seeking (...) a broader audience, the author has dropped the dissertation's numerous Latin footnotes, shortened and enlivened the chapter titles, and streamlined some of his arguments (e.g., pp. 9395 ). He has as well corrected (e.g., on Pannenberg, p. xxii; on Anselm, p. 157) or toned down (e.g., the description of monastic theology, p. 1) earlier statements. Reference to the possibility that Aquinas suffered a nervous breakdown disappears (p. 18). Still, the work remains substantially the same, reproducing even some typos (e.g., William of St. Armour [sic], p. 3) from the original. The new subtitle, Christ and Salvation in Catholic Thought from Anselm to Aquinas, is unfortunate. First, it leads one to expect a survey of the major soteriological positions articulated in the period between the two, hut such is not forthcoming. The work remains what the original title indicated, a study in the thought of Aquinas. Second, in that work Anselm plays hut a perfunctory role, serving as the foil from whose mercantile model (p. 73) or juridical mentality (p. 91) Thomas can advance to a more appropriately interpersonal grasp of the mode of our salvation. This reading of Anselm, however, leaves him in the hands of liberal Protestant historians of doctrine of the nineteenth century, and, as the bibliography indicates, it ignores more recent literature which rightly stresses the metaphysical and religious depth of Anselm's key concept of iustitia. For a precise rendering of the relation between Anselm and Aquinas, one may wish to place greater emphasis on ST III, q.14, a.I, ad 1. In that text Aquinas accomplishes two things. First, he integrates Anselm's concept of satis· faction with the traditional religious insight that, in some sense, Christ suffered what sinners deserve to suffer. At the same time he deepens the concept by rendering explicit the place of love and obedience as the formal element in satisfaction and thus rejoins Anselm in rejecting any strict notion of penal substitution. These reservations aside, the author's thorough, comprehensive, and competent investigation into Aquinas fills a lacuna in the history of soteriology, a lacuna, one regrets to say, still left open by the work of his immediate predecessor, B. Catao. At the same time the scope 148 BOOK REVIEWS of the author's work offers a further and important contribution. By researching Thomas's thought on satisfaction in the context of penance as well as soteriology, the author manages to suggest, and explicitly, that the generative matrix for Thomas's theoretic work in both areas lies in the cruciform dynamics of Christian conversion, the life of grace. With this insight he opens a door from historical theology to a contemporary systematics. Catholic University of America Washington, D.C. WILLIAM P. LOEWE Free Will and the Christian Faith. By W. S. ANGLIN. Oxford: Clarendon Press, 1990. Pp. vii + 218. $55.00 (cloth). W. S. Anglin, a Post-Doctoral Research Fellow in Mathematics at McGill University, has produced a highly compact and compelling volume which attempts in just 218 pages to prove God's existence, to argue for personal immortality, to defend the coherence of theism against the problem of evil, to provide cogent analyses of both omnipotence and omniscience, and to examine criteria for distinguishing divine revelation from other forms of communication. The thread holding these rather motley swatches of cloth together is the author's concentration on libertarian freedom which weaves throughout the above issues in one way or another. It shows up in the expected places (e.g., in the so-called 'free will defense' of the problem of evil) but also in places hitherto unexpected (Anglin nicely argues that if humans are truly free in the libertarian sense, then it is appropriate and necessary that the Scriptures take the...

The striking synthetic effort made by Bohr to unite radiation facts with atomic structure facts led to the formulation of his “quantum theory of atomic structure,” which with a large group of subsequent developments, is now usually referred to as the “classical quantum theory.” As a conceptual aid it takes over the idea of an “astronomical atom” consisting of a positive nucleus around which electrons revolve in definite orbits, more or less in the fashion of the solar system. More or (...) less. The similarities and differences as a bit of description are interesting and impressive, but when the theory is reduced to its postulates—and it is this which interests us here—it sounds very much like a re-statement of the Planckian decisions.

Mit diesem klaren und provokativen erkenntnistheoretischen Ansatz im Bereich der Religionsphilosophie argumentiert William P. Alston, dass die Wahrnehmung Gottes eines der wichtigsten Beitrage zu den Grunden des religiosen Glaubens liefert. Dabei spielt sein Begriff des direkten erfahrungsmassigen Bewusstsein eine entscheidende Rolle. Nach einem Uberblick uber verschiedene berichtete direkte Gotteserfahrungen zeigt Alston, dass eine Person auf der Grundlage der mystischen Erfahrung berechtigt ist, an Gott zu glauben. "Dieses grossartige Buch ist die Frucht von Jahrzehnten des Reifens und der durchdringenden Reflexion. (...) Wie zu erwarten war, nimmt es die Diskussion des umgebenden Themas der Gotteserfahrung auf und fuhrt es zu einer neuen Ebene der Einsicht und der Durchdringung." Alvin Plantinga, Universitat von Notre Dame, USA "Die Erkenntnistheorie des religiosen Glaubens war vor einiger Zeit das heisseste Thema der Religionsphilosophie. Alstons Arbeit ist der beste und interessanteste Beitrag zu diesem Gebiet. Alston ist nicht nur mit der Verteidigung des religiosen Glaubens beschaftigt, sondern er eroffnet einen plausiblen Vorschlag zum verbesserten Verstandnisses der Frage nach der Entstehung des religiosen Glaubens. Gott wahrnehmen ist sicher der wichtigste Beitrag zur Religionsphilosophie in diesem Jahr." Robert Merrihew Adams, Universitat von Califonien, Los Angeles". (shrink)

First published in 1977. Ethics is the most practical branch of philosophy: its immediate concern is with people's actions. Yet most philosophers do little to relate ethics intelligibly to the human situation. In this inquiry into the nature of ethics, William Ash draws on the relevant works of Marx, Engels, Lenin and Stalin to present the theory and practice of Marxist ethics. He offers an explanation of the moral aspect of Marx's dictum: 'The philosophers have only interpreted the world, (...) in various ways; the point, however, is to change it.' The book includes, perhaps for the first time in so considered a form, an assessment of Mao Tsetung's contribution to Marxist moral philosophy, together with the ethical implications of such developments in social practice as the Proletarian Cultural Revolution. The author deals with the question of value by analysing the concept of 'good'; with the question of claims on people and things by analysing the concept of 'right'; with the question of the limits and scope of freedom of choice and action by analysing the concept of 'ought'.' Clearly written in order to 'de-mystify' the subject, the book challenges readers to test the author's enlightened, Marxist approach in terms of the ethical ordering of their own society. (shrink)

The warmest, funniest, most erudite and ambitious philosophical dialogue of the twenty-first century? A lonely professor in a bookstore café overhears someone trying to explain Wittgenstein to a good friend--the two of them once having come close to an adulterous affair? The professor surreptitiously records their conversation, and then adds on top of it all his own ideas about Wittgenstein's philosophy, biography and psychology. A post-modern, Platonic exploration of how and why we human beings still try to speak and be (...) heard. All our life in language (our most sophisticated philosophies included) keeps revolving around the fixed point of our real if unmeetable need: to find love and understanding? (shrink)

On October 8th 2000 municipal elections were held in Belgium to renew the local councils which had been elected in 1994. In the Walloon region and in Flanders in addition provincial elections were organised. The aim of the article is to try and measure globally where the political forces stand after these elections and among others to assess whether significant swings have take place since june 13th, 1999, when the latest parliamentary and regional elections took place. On the basis of (...) an estimation of the global results in the municipal elections of the various parties in the Walloon region, in Flanders and in Brussels, backed up by the actual results of the provincial elections, one can say that the liberal group bas strengthened its first position.The Christian democrats, who make up the second most important political group and the Socialists, who rank third, have regained a large part of the losses they incurred onjune 13th, 1999.Although improving their results in comparison with 1994, the Green parties lost again part of their advance they registered in the parliamentary and regional elections and which had probably been boosted by the dioxin crisis.The frenchspeaking far right practically disappears, whereas the Vlaams Blok obtained an average of 15 % of the Flemish electorate in the municipal and provincial elections, a level which it had reached in the 1999 parliamentary elections.

Volume III of a tetralogy devoted to Divine Agency and Divine Action articulates a comprehensive vision of systematic theology focused on divine action from creation to eschatology.

Paralogismen betreffs der Leibnizschen Prädikatlehre werden aufgezeigt und widerlegt. Enthaltensein heißt die Inverse von Ableitung; den zwei Arten von Ableitung, die Leibniz kennt, entsprechen zwei Arten von Enthaltensein. Die beiden Arten von Enthaltensein bieten Leibniz die Möglichkeit zu der logischen und irreduziblen Unterscheidung zwischen notwendigen und bedingten Wahrheiten. Die Unterscheidung zwischen einem Individuum und einer Eigenschaft wird mit mengentheoretischen Methoden und auch mit Hilfe von epistemologischen Begriffen untersucht. Die besondere kategorische Form des Aussagesatzes impliziert, daß es für alle Aussagesätze nur (...) eine einzige Tiefen-Grammatik gibt, welche wesentlich verschiedene Ausdruckweisen von kategorischen Aussagen umfaßt.

Consider intense moments when you have been seized by joy or, in different contexts, by anguish for another person, or a cat or dog, or perhaps even for a squirrel or possum struck as it dashed across the road: whether glorious or haunting, these are among the most profound and meaningful moments in our lives. Agape Ethics focuses our attention on such moments with utter seriousness and argues they reveal a spiritual reality, the reality of agape. Powerful streams of modern (...) Western rationality reject the idea of agape. This has created a crisis of foundations in modern ethics and alienated us from love for all creatures. Working wholly within the bounds of reason, Agape Ethics joins an increasingly vibrant struggle to legitimate the spiritual reality of agape, to awaken people to its power, to clarify its ethical implications, and to validate our spiritual communion with all creatures in all creation. The result is a powerful, inclusive, and wholly reasonable defense of moral realism that should speak to all who are passionate about creating a maximally loving and good world. (shrink)

In Salvation in Writing , William Wright derives from Calvin’s theology of justification and sanctification a dialectical logic for writing truth that both rivals and mends those of Hegel and Derrida. The result represents a new program for academic theology.

Essays on Greek philosophy and literature from Homer and Hesiod to Aristotle. In Logoi and Muthoi, William Wians builds on his earlier volume Logos and Muthos, highlighting the richness and complexity of these terms that were once set firmly in opposition to one another as reason versus myth or rationality versus irrationality. It was once common to think of intellectual history representing a straightforward progression from mythology to rationality. These volumes, however, demonstrate the value of taking the two together, (...) opening up and analyzing a range of interactions, reactions, tensions, and ambiguities arising between literary and philosophical forms of discourse, including philosophical themes in works not ordinarily considered in the canon of Greek philosophical texts. This new volume considers such topics as the pre-philosophical origins of Anaximander’s calendar, the philosophical significance of public performance and claims of poetic inspiration, and the complex role of mythic figures (including perhaps Socrates) in Plato. Taken together, the essays offer new approaches to familiar texts and open up new possibilities for understanding the roles and relationships between muthos and logos in ancient Greek thought. “This is a stellar effort. The essays are all of extremely high quality and interest. The scholarship is rigorous and the content is innovative. The conception of the book is highly original, well-grounded, and well-thought-out. William Wians’s work as a scholar and as an editor has been consistently first-rate, and with this volume he has surpassed himself.” — Rose M. Cherubin, George Mason University. (shrink)

Autobiography and Teacher Development in China investigates the roles of autobiography in teacher education, as several scholars in China recontextualize Western conceptions of teacher development, combining them with uniquely Chinese cultural conceptions to articulate a reconceptualization of teacher development that holds worldwide significance. Framed by the work of Zhang Hua and William F. Pinar, these theoretical and practical essays point to an internationally inflected reconceptualization of teachers' professional development, pre-service and in-service. This volume addresses multiple movements of teacher education (...) reform worldwide, focused on crafting a nationally distinctive course not only internationally, but also culturally, historically, and locally.

Theorists of learning, regulation, and evolution explain behavior using remarkably different concepts because of pressures toward specialization, a focus on testing simple causal theories that underconceptualize the contributions of the organism and its environment, and the absence of a working model capable of surviving in a complex environment. We add suggestions for the development and testing of such a model.

In this paper it is claimed that beliefs, feelings, and actions are typically complex phenomena which have simpler components. In particular, beliefs often involve feelings and actions, while actions involve feelings and beliefs, and feelings involve beliefs and actions. It is then suggested that unconscious beliefs and commitments, both ontological and otherwise, may be discovered by the examination of actions and feelings. While these will vary from one individual to another, it is suggested that it may be possible to form (...) certain generalizations which are of philosophical interest. (shrink)
