The ability to improve in speed and accuracy as a result of repeating some task is an important hallmark of intelligent biological systems. Although gradual behavioral improvements from practice have been modeled in spiking neural networks, few such models have attempted to explain cognitive development of a task as complex as addition. In this work, we model the progression from a counting-based strategy for addition to a recall-based strategy. The model consists of two networks working in parallel: a slower basal (...) ganglia loop and a faster cortical network. The slow network methodically computes the count from one digit given another, corresponding to the addition of two digits, whereas the fast network gradually “memorizes” the output from the slow network. The faster network eventually learns how to add the same digits that initially drove the behavior of the slower network. Performance of this model is demonstrated by simulating a fully spiking neural network that includes basal ganglia, thalamus, and various cortical areas. Consequently, the model incorporates various neuroanatomical data, in terms of brain areas used for calculation and makes psychologically testable predictions related to frequency of rehearsal. Furthermore, the model replicates developmental progression through addition strategies in terms of reaction times and accuracy, and naturally explains observed symptoms of dyscalculia. (shrink)

The present issue of Filozofski Vestnik starts from a concatenation – science and thought – that at first sight is the radical opposite to Heidegger’s diagnosis. The title of this issue, “Science and Thought”, already suggests that there is or at least there can be such a relation. With regard to Heidegger, this implies two options here: either Heidegger was wrong in his criticism of metaphysics or he was wrong with his equation of Ge-Stell (as the essence of technology) and (...) science. Simply put: either metaphysics still contains some sort of valuable thought (and hence there could be some sort of metaphysical science that thinks) or science is simply not reducible to the metaphysics or to the being of a mere technology in the sense that Heidegger criticized. Then the (metaphysical) question of being could be separated from technology and metaphysics, but perhaps it still finds its locus rather within science. Heidegger’s claim about metaphysics and technology then would find itself inverted through the suggested relation of science and thought. Such an inversion of Heidegger’s critique of the very status of science is itself conditioned by the recent developments in philosophy that we take as the starting point for the present issue of Filozosfki Vestnik.

Voelker offers a powerful, inclusive practice that is appropriate for new students or long-time practitioners-and can easily be adopted by yoga instructors, educators, medical professionals, exercise professionals, caretakers, or community workers for work with their clients, students, and patients. This book highlights 40 active and restorative poses, including individual and partner poses, breathing techniques, and meditation practices, all adapted so that students never have to leave their chairs. For every pose, Voelker offers at least three different ways of experiencing it, (...) depending on an individual's level of flexibility and suggests ways to incorporate breath work and chanting. Voelker includes healthy lifestyle, practices and teaching tips, along with yoga philosophy "lessons" throughout. Voelker believes that yoga is only yoga when you make it your own; otherwise it's just exercise. It becomes therapeutic, and even transformational, when the poses, breathing techniques, and meditation practices morph and change to fit your unique body, mind, and heart. The yoga she presents is designed to encourage you to experience the joy in every pose; to celebrate your unique qualities; and to stretch your imagination and creativity, as well as your body and your mind, in ways that feel just right for you.

The Essays on the Active Powers of Man was Thomas Reid's last major work. It was conceived as part of one large work, intended as a final synoptic statement of his philosophy. The first and larger part was published three years earlier as Essays on the Intellectual Powers of Man. These two works are united by Reid's basic philosophy of common sense, which sets out native principles by which the mind operates in both its intellectual and active aspects. The (...) Active Powers shows how these principles are involved in volition, action, and the ability to judge morally. Reid gives an original twist to a libertarian and realist tradition that was prominently represented in eighteenth-century British thought by such thinkers as Samuel Clarke and Richard Price.

This article explores silence and the ethics of conscience through a study of the life and late letters of Sir Thomas More. More's silence is a paradigm case for the contest of conscience under conditions of tyranny, and it is one of the most influential in the formulation of principles of conscience and human rights in modern constitutional democracies. The article focuses on More's prosecution by King Henry VIII, and offers close analysis of the concept of conscience discussed in (...) his last letters. The approach is historical and philosophical, and puts More's case in dialogue with other classic and modern texts on the ethics of conscience. Emphasis is placed on More's principle of self-determination as essential to conscience. (shrink)

Le De Corpore, publie pour la premiere fois en 1655, est non seulement l'oeuvre majeure de Hobbes en matiere de logique, de philosophie premiere et de physique, mais egalement un des plus grands textes metaphysiques du XVIIe siecle. On y trouve une theorie de la logique comme calcul dont l'un des elements decisifs est une critique du langage en vue de determiner exactement les modalites par lesquelles nous signifions nos pensees et designons les choses. Cette logique est la condition d'une (...) philosophie premiere sur laquelle repose une nouvelle conception du monde. La theorie physique dans sa totalite, ainsi que plusieurs aspects de l'ethique et de la politique, dependent d'une telle position metaphysique. (shrink)

I argue that Kuhn's account of scientific practice is profitably understood as a kind of hinge epistemology: like our epistemic practices more generally, scientific inquiry is made possible precisely by the fact that certain things are not subject to doubt. In Kuhn's own words, ‘dogmatism’ is essential to scientific practice and one of the primary engines of its success. For this reason, I argue that Kuhn's account is a rich source for reflection on the relationship between faith and reason. At (...) the same time, Kuhn has faced objections similar to those which have faced hinge-epistemologists: how can disputes grounded in different, incompatible ‘dogmas’ be rationally resolved? Kuhn's response is similar to one put forward by Duncan Pritchard, but is, I argue, an improvement on it. In particular, the hinges on which deep scientific disagreement turns are for Kuhn certain shared values in light of which debate is possible. The choice among competing dogmas can, I argue, be understood on analogy with a prudential judgement of practical reasoning, i.e., an exercise of phronēsis. (shrink)

"The complete list of the works of Thomas S. Szasz": pages 237-253.

Thomas Aquinas produced a voluminous body of work on moral theory, and much of that work is on virtue, particularly the status and value of the virtues as principles of virtuous acts, and the way in which a moral life can be organized around them schematically. Thomas Osborne presents Aquinas's account of virtue in its historical, philosophical and theological contexts, to show the reader what Aquinas himself wished to teach about virtue. His discussion makes the complexities of Aquinas's (...) moral thought accessible to readers despite the differences between Thomas's texts themselves, and the distance between our background assumptions and his. The book will be valuable for scholars and students in ethics, medieval philosophy, and theology. (shrink)

The impassioned democratic voice of the Age of Revolution, Paine possessed a gift for stating complex ideas in concise language. This accessible collection of highlights from the social and political philosopher's best-known works includes lengthy selections from Common Sense , The American Crisis , The Rights of Man , and The Age of Reason.

Contemporary Philosophy in Focus offers a series of introductory volumes to many of the dominant philosophical thinkers of the current age. Thomas Kuhn, the author of The Structure of Scientific Revolutions, is probably the best-known and most influential historian and philosopher of science of the last 25 years, and has become something of a cultural icon. His concepts of paradigm, paradigm change and incommensurability have changed the way we think about science. This volume offers an introduction to Kuhn's life (...) and work and then considers the implications of Kuhn's work for philosophy, cognitive psychology, social studies of science and feminism. The volume is more than a retrospective on Kuhn, exploring future developments of cognitive and information services along Kuhnian lines. Outside of philosophy the volume will be of particular interest to professionals and students in cognitive science, history of science, science studies and cultural studies. (shrink)

Aquinas occupies an extremely important position in the western philosophical tradition. His work contains influential contributions in logic, metaphysics, theory of knowledge, ethics and philosophy of religion, and his commentaries on Aristotle played a major role in the incorporation of the philosophy of Aristotle into the understanding of Christian doctrine and into western culture at large. Yet many people find it difficult to begin the study of Aquinas's work, daunted by its volume and by its being worked out within in (...) the context of Catholic doctrine, which must now be obscure to most readers. This book can help rectify this. (shrink)

Thomas Aquinas, John Duns Scotus, and William of Ockham disagree over how and whether virtues are specified by their objects. For Thomas, habits and acts are specified by their formal objects. For instance, the object of theft is something that belongs to someone else, and more particularly theft is distinct from robbery because theft is the open taking of another’s good, whereas robbery is open and violent. A habit such as a virtue or a vice shares or takes (...) the act’s object. For Scotus, although the same virtue or act cannot have objects which differ formally, different virtues and acts can have an object which is identical according to its formal ratio, in the way that the different theological virtues might even formally have God as their object. Ockham accepts Scotus’s view that charity and hope are two kinds of love, we will see how, unlike Scotus, he argues that these theological virtues differ on account of their immediate complex objects. The disagreement between these three figures raises important difficulties concerning what it even means to be a formal object. (shrink)

Thomas Paine was a hugely influential revolutionary pamphleteer, whose writings were instrumental in bringing about some of the greatest political changes the world has seen. Paine's enduring importance lies not so much in the depth of his political philosophy as in his great abilities as a communicator of political ideas. Conway's Writings was the first complete critical collection of Paine's works, and his Life was the first account to show Paine in a positive light.

'Moge onze keuze het signaal zijn voor de oproep aan mensen om de ketenen te verbreken, waaronder de monnikachtige onwetendheid en het bijgeloof, die hen ertoe hadden overreed zichzelf vast te binden, en om de zegeningen en veiligheid van het zelfbestuur te aanvaarden.'.

Thomas Reid is now recognized as one of the towering figures of the Enlightenment. Best known for his published writings on epistemology and moral theory, he was also an accomplished mathematician and natural philosopher, as an earlier volume of his manuscripts edited by Paul Wood for the Edinburgh Reid Edition, Thomas Reid on the Animate Creation, has shown. The Correspondence of Thomas Reid collects all of the known letters to and from Reid in a fully annotated form. (...) Letters already published by Sir William Hamilton and others have been reedited, and roughly half of the letters included appear in print for the first time. Writing in 1802, Reid's disciple and biographer Dugald Stewart doubted that Reid's correspondence &"would be generally interesting.&" This collection proves otherwise, for the letters illuminate virtually every aspect of Reid's life and career and, in some instances, provide us with invaluable evidence about activities otherwise undocumented in his manuscripts or published works. Through his correspondence we can trace Reid's relations with contemporaries such as David Hume and his colleagues at both King's College, Aberdeen, and the University of Glasgow, as well as his engagement with the most controversial philosophical, scientific, and political issues of his day. If anything, the letters assembled here serve as the starting point for understanding Reid and his place in the Enlightenment. (shrink)

This book contains the text of Thomas Kuhn's unfinished book, The Plurality of Worlds: An Evolutionary Theory of Scientific Development, which Kuhn himself described as "a return to the central claims of The Structure of Scientific Revolutions, and the problems that it raised but did not resolve." The Plurality of Worlds is preceded by two related texts that Kuhn publicly delivered but never published in English: his paper "Scientific Knowledge as a Historical Product" and his Shearman Memorial Lectures, "The (...) Presence of Past Science." The book opens with an introduction by the editor that describes the origins and structure of The Plurality of Worlds, and sheds light on its central philosophical problems. Kuhn's aims in his last writings are bold. He sets out to develop an empirically grounded theory of meaning that would allow him to make sense of both the possibility of historical understanding and the inevitability of incommensurability between past and present science. Moreover, he intends to show that incommensurability is fully compatible with a robust notion of a real world that science investigates, with the rationality of scientific belief change, and with the idea that scientific development is progressive. This is a must-read follow-up to The Structure of Scientific Revolutions, one of the most important books of the twentieth century. (shrink)

Aussi ancienne, par les sujets abordes, que l'histoire de la philosophie, la controverse qui opposa Thomas Hobbes a John Bramhall commenca lors d'une rencontre qui se deroula en 1645 et s'acheva par une publication qui eut lieu en 1682, alors que les deux adversaires etaient morts.Elle excita d'autant plus la verve de Hobbes que les questions de philosophie naturelle, de theologie et de theorie politique sur lesquelles elle roula et rebondit en plusieurs occasions etaient de celles dont il devait (...) ecrire, dans le Behemoth, qu'elles avaient ete la cause de tous nos malheurs recents, autrement dit de la revolution et de la guerre civile: le libre arbitre, les substances incorporelles, l'eternite, l'incarnation, l'heresie, la piete et le devoir d'obeissance au souverain.
