We develop a modified system of standard logic, Augmented Standard Logic (ASL), and we employ ASL in an effort to show that, contrary to prevailing opinion, both Aristotle and Diodorus presented impressive arguments, having valid structures and highly plausible premisses, in their famous fatalism debate. We argue that ASL, which contains standard logic and a full system of modal and temporal logic emanating from a modicum of primitives, should not only enable one to appreciate the sophisticated philosophizing which characterized this (...) ancient debate, but should prove to be quite useful in application to contemporary issues.

The sense of agency is the perception of willfully causing something to happen. Wegner and Wheatley proposed three prerequisites for SA: temporal contiguity between an action and its effect, congruence between predicted and observed effects, and exclusivity . We investigated how temporal contiguity, congruence, and the order of two human agents’ actions influenced SA on a task where participants rated feelings of self-agency for producing a tone. SA decreased when tone onsets were delayed, supporting contiguity as important, but the order (...) of the agents’ actions also mattered. Relative contiguity was the main determinant of SA, as delayed tones were usually attributed to the most recent action. This was unaffected by contingencies between the two actors’ actions , showing that contiguity has a powerful influence on SA, even during joint action in the presence of other cues. (shrink)

We studied how people determine when they are in control of objects. In a computer task, participants moved a virtual boat towards a goal using a joystick to investigate how subjective control is shaped by (1) correspondence between motor actions and the visual consequences of those actions, and (2) attainment of higher-level goals. In Experiment 1, random discrepancies from joystick input (noise) decreased judgments of control (JoCs), but discrepancies that brought the boat closer to the goal and increased success (the (...) autopilot) increased JoCs. In Experiment 2, participants raced to the goal against a computer-controlled rival boat while varying levels of noise interfered with each boat. Participants reached the goal more often and rated their own control higher when the computer rival had good control. Subjective control over moving objects depends partly on consistency between motor actions and their effects, but is also modulated by perceived success and competition. -/- Keywords: Control; Action; Feedback; Competition .

Self-initiated action effects are often perceived as less intense than identical but externally generated stimuli. It is thought that forward models within the sensorimotor system pre-activate cortical representations of predicted action effects, reducing perceptual sensitivity and attenuating neural responses. As self-agency and predictability are seldom manipulated simultaneously in behavioral experiments, it is unclear if self-other differences depend on predictable action effect contingencies, or if both self- and externally generated stimuli are modulated similarly by predictability. We factorially combined variation in predictability (...) of action effects, spatial congruence, and performance by the self or computer to dissociate these influences on a visual discrimination task. Participants performed 2AFC speed judgments. Self-initiated motion was judged to be slower than computer-initiated motion when action effect contingencies were predictable, while spatial congruence influenced speed judgments only when action effect contingencies were unpredictable. Results are discussed in relation to current theories of sensory attenuation. (shrink)

The phenomenology of controlled action depends on comparisons between predicted and actually perceived sensory feedback called action-effects. We investigated if intervening task-irrelevant but semantically related information influences monitoring processes that give rise to a sense of control. Participants judged whether a moving box “obeyed” or “disobeyed” their own arrow keystrokes or visual cues representing the computer’s choices . During 1 s delays between keystrokes/cues and box movements, participants vocalized directions cued by letters inside the box. Congruency of cued vocalizations was (...) manipulated relative to previously selected keystrokes and upcoming box movements. In Experiment 1, reported obey moves and feelings of control reflected the true frequency of obey moves, but were also modulated by vocalizations. Incongruent vocalizations reduced reported obey moves, whereas congruent vocalizations increased them. In Experiment 2, vocalizations had stronger effects when their congruence with primary-task box movement was consistent for several consecutive moves before congruence changed. In Experiment 3, analogous impacts of vocalizations occurred when the computer selected the directions and participants judged whether the computer had control of the box. We conclude that predicted and perceived action-effects associated with semantically related but separate and ostensibly irrelevant actions can be conflated with one another. This interference is not restricted to actions performed with the same effector or within the same modality, or even by the same actor. Thus in estimating degrees of control, the mind integrates across ongoing action systems, whether or not they are logically task-relevant. (shrink)

Much of Thomas Hobbes's work can be read as historical commentary, taking up questions in the philosophy of history and the rhetorical possibilities of written history. This collection of scholarly essays explores the relation of Hobbes's work to history as a branch of learning.

This paper advances a continuing line of research investigating the potential of web-based educative curriculum materials (ECMs) to facilitate teachers’ development of professional teaching knowledge (PTK). Our ECMs consisted of online lesson plans scaffolded with embedded digital resources to promote teacher understanding of a particular wise-practice pedagogy: problem-based historical inquiry (PBHI). Our research question was: Can a 2nd generation of web-based ECMs encourage social studies teachers’ development of PTK for PBHI? Participants reacted positively to several educative scaffolds, especially videocases of (...) experts modeling historical thinking. Evidence suggested that multiple experiences with planning and implementing instruction with our ECMs helped teachers recognize value in some of the materials’ underpinning concepts (e.g., scaffolding and inquiry-based instruction). However, planning instruction individually, the novelty of planning resources enhanced with digital resources, and certain contextual features of schooling such as inadequate focused time for planning seemed to frustrate the ECMs potential to promote teacher-learning. Here we suggest that ECMs function less effectively as stand-alone supports; however, employed in more formal contexts that feature collaboration, they may be able to provide valuable support for teachers’ professional development.

The success of deep brain stimulation (DBS) for movement disorders and the improved understanding of the neurobiologic and neuroanatomic bases of psychiatric diseases have led to proposals to expand current DBS applications. Recent preclinical and clinical work with Alzheimer's disease and obsessive-compulsive disorder, for example, supports the safety of stimulating regions in the hypothalamus and nucleus accumbens in humans. These regions are known to be involved in addiction and overeating associated with obesity. However, the use of DBS targeting these areas (...) as a treatment modality raises common ethical considerations, which include informed consent, coercion, enhancement, threat to personhood, and manipulation of the reward center. Pilot studies for both of these conditions are currently investigational. If these studies show promise, then there is a need to address the ethical concerns related to the initiation of clinical trials including the reliability of preclinical evidence, patient selection, study design, compensation for participation and injury, cost-effectiveness, and the need for long-term follow-up. Multidisciplinary teams are necessary for the ethical execution of such studies. In addition to establishing safety and efficacy, the consideration of these ethical issues is vital to the adoption of DBS as a treatment for these conditions. We offer suggestions about the pursuit of future clinical trials of DBS for the treatment of addiction and overeating associated with obesity and provide a framework for addressing ethical concerns related to treatment.

In Marc. gr., classis XI,18 an anonymous florilegium consisting of selected paragraphs of the Second Part of the Fifth Division of the 3rd book of Thomas Aquinas’ Summa contra Gentiles is extant. These paragraphs were excerpted from the Greek translation of the Latin text by Demetrios Cydones and 106 ; ch. 101, § 2 partim; 103; ch. 94, § 3-5; 12-15). The main topic of this text is «fate». An edition of it is offered, and it is argued, on (...) the basis of its similarity with another florilegium Thomisticum of the professed Byzantine Thomist Georgios Scholarios - Gennadios II as well as with some of his writings, that it must be attributed to the same author. It should be probably placed in 1444/53 and regarded as part of Scholarios’ preparation for refuting Georgios Gemistos - Plethon’s Laws II,6, which from 1439 onwards was circulated independently as De fato.

We show how trajectories can be reintroduced in quantum mechanics provided that its spatial continuum is modelled by a variable real number (qr-number) continuum. Such a continuum can be constructed using only standard Hilbert space entities. In this approach, the geometry of atoms and subatomic objects differs from that of classical objects. The systems that are non-local when measured in the classical space-time continuum may be localized in the quantum continuum. We compare trajectories in this new description of space-time with (...) the corresponding Bohmian picture. (shrink)

This is a report of the progress and activities of the project Thomas de Aquino Byzantinus during the last two years, with an emphasis on the Thomism of Bessarion and Scholarios and the transmission of some of Averroes’ doctrines in late Byzantium via the translation of some of Aquinas’ writings into Greek.

A dramatic retelling of the story of the Transcendentalists, revealing them not as isolated authors but as a community of social activists who shaped progressive American values. Conflagration illuminates the connections between key members of the Transcendentalist circle—including James Freeman Clarke, Elizabeth Peabody, Caroline Healey Dall, Elizabeth Stanton, Thomas Wentworth Higginson, Theodore Parker, and Margaret Fuller—who created a community dedicated to radical social activism. These authors and activists laid the groundwork for democratic and progressive religion in America. In the (...) tumultuous decades before and immediately after the Civil War, the Transcendentalists changed nineteenth-century America, leading what Theodore Parker called “a Second American Revolution.” They instigated lasting change in American society, not only through their literary achievements but also through their activism: transcendentalists fought for the abolition of slavery, democratically governed churches, equal rights for women, and against the dehumanizing effects of brutal economic competition and growing social inequality. The Transcendentalists’ passion for social equality stemmed from their belief in spiritual friendship—transcending differences in social situation, gender, class, theology, and race. Together, their fight for justice changed the American sociopolitical landscape. They understood that none of us can ever fulfill our own moral and spiritual potential unless we care about the full spiritual and moral flourishing of others. (shrink)

Is logical empiricism incompatible with a critical social science? The longstanding assumption that it is incompatible has been prominent in recent debates about welfare economics. Sen’s development of a critical and descriptively rich welfare economics is taken by writers such as Putnam, Walsh and Sen to involve the excising of the influence of logical empiricism on neo-classical economics. However, this view stands in contrast to the descriptively rich contributions to political economy of members of the left Vienna Circle, such as (...) Otto Neurath. This paper considers the compatibility of the meta-theoretical commitments of Neurath and others in the logical empiricist tradition with this first-order critical political economy. (shrink)

Taking as their departure point the political-philosophical analyses of German scholar Tilo Schabert, the philosophical and empirical essays in this volume invite the reader to move beyond the sterile dichotomy of political activity as either pure will or as folded into a more manageable activity.

Hahn held on February 19, 2005, and were compiled for presentation here by Sharon (Hahn) Crowell.A Tribute to Dr. Lewis E. Hahn (1908-2004) from a Global PerspectiveGeorge C. H. Sun President, Thomé H. Fang Institute, Inc., Mobile, AlabamaAmong the philosophical community in both the East and the West, no word of introduction is needed for our beloved Master, who was the recipient of numerous distinctions and honors, with titles that included "Man of the Year in Philosophy" and "Award of Lifetime Achievement." The very name "Lewis E. Hahn" itself already stands now for genuineness, dedication, and fulfillment.A great work is a dialogue with eternity; a great person is such a work. In less than thirty years he succeeded in developing Carbondale from what had been a small college town in the Midwest into the Mecca of American philosophy. His most important achievements were the Dewey Center and the Pepper Archives that he helped install at SIUC These, among other such institutions, will remain a unique contribution, a glory of American philosophy, and a monument in the history of human thought.For posterity Lewis E. Hahn will remain an object of wonder and amazement. How is it possible for one human being to have accomplished so much, so well, and in so short a span of time—less than one century—in breadth, depth, and diversity? Some one hundred years ago, by bridging the gap between the New World and the Old, William James was hailed as the great genius of international friendship among philosophical thinkers, but we now find a greater genius in Lewis E. Hahn, who succeeded in bringing together the peoples of East and West from at least four continents: Europe, Australia, America (both North and Latin America), and Asia. To my knowledge, few of his predecessors and contemporaries have been half so widely read and liberal-minded as he was, in view of the range and scope of the Library of Living Philosophers that he helped continue after the passing of its founder, Dr. Paul A. Schilpp.What type of man was Hahn, our younger generation will wonder? Only a pluralist approach can help us understand the true character of such a legendary pluralist-contextualist. In short, he was "a full personality." As I recall, while working on my dissertation with him in the 1970s, we had a brief discussion on Confucius, the sage of ancient China. "A full personality!" was his laconic assessment. Suddenly I realized, to quote the Analects: "The Master is talking about himself!" For, as the Buddhists put it, only a Buddha can understand a Buddha. Or, as William James put it, only one who has philosophy can appreciate philosophy. Many friends [End Page 1] of my generation admire him so much; Te Chen of Hong Kong calls him "a great Confucian in America." Those who regret the loss of many precious Confucian virtues in China today have now rediscovered them in the person of Lewis E. Hahn! If Nietzsche called Kant "a great Chinese in Königsberg," it is simply because he had not encountered our own Master.A paradigm of academic leadership, Dr. Hahn is simply irreplaceable—this is a tribute I personally heard in Carbondale in the late 1960s. It is not an exaggeration to say that he was a superb administrator, and he could have been the best Secretary of the State we ever had, for he possessed more in the way of philosophical wisdom than all his predecessors put together! As a great teacher, he was no less "serene, good, learned, wise, and ardent" than... (shrink)

In _A Common Faith,_ eminent American philosopher John Dewey calls for the “emancipation of the true religious quality” from the heritage of dogmatism and supernaturalism that he believes characterizes historical religions. He describes how the depth of religious experience and the creative role of faith in the resources of experience to generate meaning and value can be cultivated without making cognitive claims that compete with or contend with scientific ones. In a new introduction, Dewey scholar Thomas M. Alexander (...) contextualizes the text for students and scholars by providing an overview of Dewey and his philosophy, key concepts in _A Common Faith,_ and reactions to the text. (shrink)

We propose category theory, the mathematical theory of structure, as a vehicle for defining ontologies in an unambiguous language with analytical and constructive features. Specifically, we apply categorical logic and model theory, based upon viewing an ontology as a sub-category of a category of theories expressed in a formal logic. In addition to providing mathematical rigor, this approach has several advantages. It allows the incremental analysis of ontologies by basing them in an interconnected hierarchy of theories, with an operation on (...) the hierarchy that expresses the formation of complex theories from simple theories that express first principles. Another operation forms abstractions expressing the shared concepts in an array of theories. The use of categorical model theory makes possible the incremental analysis of possible worlds, or instances, for the theories, and the mapping of instances of a theory to instances of its more abstract parts. We describe the theoretical approach by applying it to the semantics of neural networks. (shrink)
