Brouwer's Life, Art and Mysticism is the ideological manifesto of one of the greatest mathematical philosophers of this century. It is a seemingly contradictory declaration of romantic rebellion against rationalism and science by a man who brought constructivist rigor to mathematical and logical practice; the emotional plea of a fanatical environmentalist for a return to `nature', a defiant call to reject the formal trappings of society arising from a deep resentment of authority and of the intellectual and social aspects of (...) the human make-up.

Dutch Mathematician Luitzen Egbertus Jan Brouwer (1881-1966) was a rebel. His doctoral thesis... was the manifesto of an angry young man taking on the mathematical establishment on all fronts. In a short time he established a world-wide reputation for himself; his genius and originality were acknowledged by the great mathematicians of his time... The Intuitionist-Formalist debate became a personal feud between the mathematical giants Brouwer and Hilbert, and ended in 1928 with the expulsion of Brouwer from the editorial board of (...) the Mathematische Annalen by dictat of Hilbert. Forsaken, humiliated and disillusioned Brouwer abandoned his Intuitionist Programme and withdrew into silence just about the time when the Formalist Programme appeared to be fundamentally flawed and major opposition collapsed... This book attempts to follow the `genetic' development of Brouwer's ideas, linking the man Brouwer, his Weltanschauung, his philosophy of mathematics and his reconstruction of mathematics. Brouwer's own writings, his publications as well as his unpublished papers, are its immediate and main source of reference. It is the second volume in the new series Studies in the History and Philosophy of Mathematics, and is written for the specialist as well as for the general reader interested in mathematics and the interpretation of its status and function.

Review of a van Stigt's book Brouwer's intuitionism.

Current views of the control of complex, purposeful movements acknowledge that organizational processes must reconcile multiple concerns. The central priority is of course accomplishing the actor's goal. But in specifying the manner in which this occurs, the action plan must accommodate such factors as the interaction of mechanical forces associated with the motion of a multilinked system (classical mechanics) and, in many cases, intrinsic bias toward preferred movement patterns, characterized by so‐called “coordination dynamics.” The most familiar example of the latter (...) is the symmetry constraint, where spatial trajectories and/or temporal landmarks (e.g., reversal points) of concurrentlymoving body segments (limbs, digits, etc.) exhibit mutual attraction. The natural coordination tendencies that emerge through these constraints can facilitate or hinder motor control, depending on the degree of congruency with the desired movement pattern. Motor control theorists have long recognized the role of classical mechanics in theories of movement organization, but an appreciation of the importance of intrinsic interlimb bias has been gained only recently.Although detailed descriptions of temporal coordination dynamics have been provided, systematic attempts to identify additional salient dimensions of interlimb constraint have been lacking. We develop and implement here a novel method for examining this problem by exploiting two robust principles of psychomotor behavior, the symmetry constraint and the Two‐Thirds Power Law. Empirical evidence is provided that the relative spatial patterns of concurrently moving limbs are naturally constrained in much the same manner as previously identified temporal constraints and, further, that apparent velocity interference is an indirect, secondary consequence of primary spatial assimilation. The theoretical implications of spatial interference are elaborated with respect to movement organization and motor learning. The need to carefully consider the appropriate dimensions with which to characterize coordination dynamics is also discussed. (shrink)

Progressive supranuclear palsy is a movement disorder with prominent tau neuropathology. Brain diseases with abnormal tau deposits are called tauopathies, the most common of which is Alzheimer's disease. Environmental causes of tauopathies include repetitive head trauma associated with some sports. To identify common genetic variation contributing to risk for tauopathies, we carried out a genome-wide association study of 1,114 individuals with PSP and 3,247 controls followed by a second stage in which we genotyped 1,051 cases and 3,560 controls for the (...) stage 1 SNPs that yielded P ≤ 10-3. We found significant previously unidentified signals associated with PSP risk at STX6, EIF2AK3 and MOBP. We confirmed two independent variants in MAPT affecting risk for PSP, one of which influences MAPT brain expression. The genes implicated encode proteins for vesicle-membrane fusion at the Golgi-endosomal interface, for the endoplasmic reticulum unfolded protein response and for a myelin structural component. © 2011 Nature America, Inc.

Richard Taylor was born in Charlotte, Michigan on 5 November 1919. He received his A. B. from the University of illinois in 1941, his M. A. from Oberlin College in 1947, and his Ph. D. from Brown University in 1951. He has been William H. P. Faunce Professor of Philosophy at Brown University, Professor of Philosophy (Graduate Faculties) at Columbia University, and Professor of Philosophy at the University of Rochester. He is the author of about fifty articles and of five (...) philosophical books. This volume consists of essays presented to Richard Taylor on the occa sion of his sixtieth birthday. Some of the contributors have been Taylor'S students; some have been his colleagues; and all have been, and continue to be, his admirers. I have made several attempts to articulate what it is I (I would not presume to speak for anyone else) admire about Richard Taylor: (1) There is a particular 'flavor' to Taylor's philosophical writing and con versation that is wholly delightful. Like any other flavor, it can be tasted and enjoyed and remembered but never adequately described. (If there should be someone who has picked up this book who does not know what I mean, I recommend that he read the chapter on 'God' in Taylor's Metaphysics. ) (2) Taylor is a masterful dialectician.

How can Africans escape the control of the complex power relationships established during Colonization and successfully achieve self-development? More importantly, and the primary concern of this book, can African female characters ever hope to arrive at such individuation given the dual challenges of the power structures defined and enforced by European colonizers and the patriarchal structures that contort issues related to gender? Tracing Personal Expansion reads late 20th Century works by African female novelists Buchi Emecheta, Tsitsi Dangarembga, and Calixthe Beyala (...) as modern Bildungsromane, novels of self-development, to reveal the dynamics, complexities, and challenges the characters and authors experience. By exploring the possibility of self-development in African female protagonists, this engrossing work augments existing feminist critiques that have analyzed the possibilities and potentials for the individuation of mostly Western, mostly European female characters.

Another critical analysis of the intellectual antecedents or the logical structure of Thorstein Veblen's thought is hardly needed. Since his death—iconoclasm's reward is often posthumous—a goodly number of such studies has appeared. I do not intend to add to the pile, but rather to analyze Veblen's work as representative of the response of “intellectuals” to specific ideologies and to ideology in general. This is a subject that has not received the direct attention it deserves, and, to my knowledge, Veblen has (...) never been studied in this connection.By “ideology” I mean a system of beliefs that presents value-judgments as empirical truths in order to justify, with or without conscious intent, a particular socio-economic group's claim to material and prestigial rewards. The valuejudgments in an ideology fall into two categories: those which have to do with a hero-subject, individual or group, whom the ideologue believes worthy of the rewards, and those which concern a villain-subject, individual or group, whom the ideologue believes unworthy. To win general acceptance of these valuejudgments an ideology also contains a set of reality-statements. These, in purporting to tell the “truth” about the world—about men, nature, God—serve to objectify, and thus justify, the choice of the hero and villain-subjects. (shrink)
