Current computational models predict reward based solely on learning. Real motivation involves that but also more. Brain reward systems can dynamically generate incentive salience, by integrating prior learned values with even novel physiological states (e.g., natural appetites; drug-induced mesolimbic sensitization) to cause intense desires that were themselves never learned. We hope future computational models may capture this too.

We present a synthetic theory of skilled action which proposes that cognitive processes make an important contribution to almost all skilled action, contrary to influential views that many skills are performed largely automatically. Cognitive control is focused on strategic aspects of performance, and plays a greater role as difficulty increases. We offer an analysis of various forms of skill experience and show that the theory provides a better explanation for the full set of these experiences than automatic theories. We further (...) show that the theory can explain experimental evidence for skill automaticity, including evidence that secondary tasks do not interfere with expert performance, and evidence that experts have reduced memory for performance of sensorimotor skills.

Since there have been many recent occurrences of alleged wrongdoing by business persons and other professionals, it seems additional ethics research is needed to obtain knowledge that will impact real-world behavior. An empirical study assessed business students’ impressions of hypothetical wrongdoers and whistleblowers. To some extent, impressions of an unethical executive and a whistleblower were influenced by the same variables and in opposite directions. Female respondents judged the unethical executive less favorably and the whistleblower more favorably than did males. The (...) executive was rated less favorably and the whistleblower more favorably when the executive sought a small gain than when the goal was a large gain or prevention of a loss of either magnitude. Some manipulations, however, impacted impressions of one actor, but not the other. Perhaps ethics training can make students aware that issue␣framing and moral intensity components may bias decisions. (shrink)

Do the rich descriptions and narrative shapings of literature provide a valuable resource for readers, writers, philosophers, and everyday people to imagine and confront the ultimate questions of life? Do the human activities of storytelling and complex moral decision-making have a deep connection? What are the moral responsibilities of the artist, critic, and reader? What can religious perspectives—from Catholic to Protestant to Mormon—contribute to literary criticism? Thirty well known contributors reflect on these questions, including iterary theorists Marshall Gregory, James Phelan, (...) and Wayne Booth; philosophers Martha Nussbaum, Richard Hart, and Nina Rosenstand; and authors John Updike, Charles Johnson, Flannery O'Connor, and Bernard Malamud. Divided into four sections, with introductory matter and questions for discussion, this accessible anthology represents the most crucial work today exploring the interdisciplinary connections between literature, religion and philosophy.

The array seen when saccading across a point light source blinking in the dark is displaced in the direction of the saccade. This displacement reflects an abrupt shift of spatiotopic coordinates that precedes the actual eye movement. The extraretinal signal mediating this discrete shift appears to be an oculomotor reference signal, specifying intended eye orientation, that changes discretely before saccades.

Background U.S. federal regulations require that certain ethical elements be followed to protect human research subjects. The location and clinical circumstances of a proposed research study can differ substantially and can have significant implications for these ethical considerations. Both the location and clinical circumstances are particularly relevant for research in intensive care units (ICUs), where patients are often unable to provide informed consent to participate in a proposed research intervention. Purpose Our goal is to elaborate on the updated 2013 U.S. (...) Food and Drug Administration (FDA) guidance document regarding an exemption from the requirement of obtaining informed consent from patients or their surrogates and to address certain elements within that document, thereby assisting clinicians in developing a framework for emergency research in accordance with the regulatory bodies at their own institutions and in the United States. Methods Review of the 2011 and updated FDA guidance document on exemption from informed consent. Results The current process of obtaining informed consent within ICUs needs to be revisited, especially for research in which timely informed consent is not likely. In particular, the process of obtaining informed consent may not be appropriate or even ethical for critically ill patients in extremis who require an intervention for which there is no current acceptable standard of care and clinical equipoise exists. We provide clinicians with a viewpoint that further elaborates on the FDA guidance document. Limitations The viewpoints provided herein are those of the authors and are therefore inherently limited by the personal views of a selected few. Other clinicians or researchers may not interpret the FDA guidelines in a similar manner. Moreover, the discussion of a guideline document is a limitation in and of itself. The guidelines set forth by the FDA are precisely that—guidelines. Therefore, they may not be followed as outlined in the guidance document within one’s own institution. Our goal is that, by elaborating on the guidelines for planned research involving human subjects in the ICU, institutional regulatory bodies may gain a better understanding in drafting their own document when faced with a clinician or a researcher who wishes to conduct planned research in an ICU. Conclusions We believe that the interpretations provided will allow clinicians to safely undertake planned research in ICUs without endangering the main tenets of ethical research involving human participants. This research is needed for the advancement of care in the critically ill. (shrink)

In Truth in Aquinas Catherine Pickstock and John Milbank continue Radical Orthodoxy's ‘reinterpretation’ of the history of philosophy and theology by evaluating philosophy as metaphysics so that ‘metaphysics collapses into sacra doctrina’ in Thomas Aquinas. Their strategy for saving Aquinas from Heideggerian ‘onto‐theology’ is the opposite of that Jean‐Luc Marion who in ‘Saint Thomas d'Aquin et l'onto‐théo‐logie’ keeps philosophy and metaphysics distinct from sacred teaching. The article examines some of the questions involved by reconsidering the nature of philosophy as textual (...) commentary in late Antiquity and in the Middle Ages. It goes on to examine what Aquinas means by ‘the truth of things’, and concludes by looking at how he treats the aspects of metaphysics and the relation of metaphysics and sacra doctrina. Hankey judges that Marion is right on this question. The author suggests that what is involved with Milbank and Pickstock is not a reinterpretation of Aquinas. What they have written depends on mistakes and misrepresentations of basic points in his teaching, e.g, participation, intellectual intuition and abstractions, God's being and his existence in things, with the result that Thomas looks more like Descartes or Spinoza than himself.

Radical Orthodoxy is the most radical and influential theological development in a generation. Many have been bewildered by the range and intensity of the writings which constitute Radical Orthodoxy. This book spans the range of the history of thought discussed by Radical Orthodoxy, tackling the accuracy of the historical narratives on which their position depends. The distinguished contributors examine the history of thought as presented by the movement, presenting a series of critiques of individual Radical Orthodox 'readings' of key thinkers. (...) Contributors include: Eli Diamond, Wayne Hankey, Todd Breyfogle, John Marenbon, Richard Cross, Neil Robertson, Douglas Hedley, David Peddle, Steven Shakespeare, Hugh Rayment-Pickard, and George Pattison.

Plato, and a wide variety of ancient, Arabic, and medieval Platonisms had a significant influence on Aquinas. The Corpus, with its quasi-Apostolic origin for Aquinas, was his most authoritative and influential source of Neoplatonism. His most influential early sources of Platonism came from Aristotle and Augustine, that is besides the Dionysian Corpus and the Liber. Aquinas greatly acknowledged the Neoplatonic, and the Peripatetic, commentaries and paraphrases he gradually acquired, because they enabled getting to the Hellenic sources. A great part of (...) Aquinas's last writing was devoted to explicating Aristotle's works including the Liber de causis, which was attributed to him. Aquinas wished to understand the philosophical schools such as their characters, the differences between and within them, their memberships, influences, histories, and the extent to which they are complementary. Aquinas gave an extended treatment of the history of philosophy, including lists of differences and agreements between Plato and Aristotle, beginning with ‘the opinions of the ancients and of Plato’ in his On Separate Substances. When Aquinas treated Aristotle in On Separate Substances, he did not leave his Neoplatonic framework behind. There is much more in On Separate Substances concerning the numbers, including an elaborate reasoning that saves the verbally opposed positions of both Proclus and Dionysius. (shrink)

Aquinas contradicts Isaiah VI. 6 because of his following of the ps. Dionysius, who is in turn reproducing the logical structures of Iamblichus and Proclus. These came to prevail despite doubts raised by earlier medieval theologians with the exception of Eriugena. Here are considered Thomas’ principles of biblical interpretation and the character of his Aristotelianism. His thought is shown to be a form of neoplatonic systematizing as developed by Iamblichus and Proclus.

This paper contrasts the reception of Dionysius in relation to non-Christian philosophy during the Latin Middle Ages with his reception in twentieth-centuryChristian thought. The medievals, including Eriugena, Thomas Aquinas, Nicholas of Cusa, and many others, as a rule refuse to divide religion from philosophy and they distinguish or unite thinkers by their teaching rather than by their confessional adherence. Hence they see no need to set Dionysius in opposition to non-Christian philosophers such as Plato, Aristotle, and Proclus, or to repudiate (...) the latter in favor of the former. By contrast, Vladimir Lossky and Jean-Luc Marion, with their shared background in Etienne Gilson, celebrate Dionysius in opposition to the non-Christian Neoplatonists, whom they polemically misrepresent as reducing God to conceptual categories. These twentieth-century figures evince a sectarian religious narrowness that blinds them to the textual and philosophical community of Dionysius with his non-Christian sources. (shrink)
