A model of writing in cognitive development, Understanding the Representational Mind synthesizes the burgeoning literature on the child’s theory of mind to provide an integrated account of children’s understanding of representational and mental processes, which is crucial in their acquisition of our commonsense psychology. Perner describes experimental work on children’s acquisition of a theory of mind and representation, offers a theoretical account of this acquisition, and gives examples of how the increased sophistication in children’s theory of mind improves their understanding (...) of social interaction and how, in the case of autistic children, an impairment results in social ineptitude. He analyzes the concepts of representation and metarepresentation as they appear in current discussion in the philosophy of cognitive science and explains how the unfolding of mental representation enables infants to comprehend change over time, engage in pretence, and use representational systems like pictures and language. Perner goes on to show that around age four children become able to understand the representational nature of pictures and language and to distinguish appearance from reality. Introducing basic distinctions in philosophy of mind for characterizing the mental, Perner discusses differences in how commonsense and cognitive psychology view the mind. Tracing the onset of a commonsense psychology in the social and emotional awareness of early infancy, he reveals how the child begins to take a cognitive, representational view of the mind with repercussions for children’s episodic memory, self control, and their ability to engage in deception. Perner concludes by describing the observed developmental changes as a case of theory change And contrasts his thesis with competing proposals. Josef Perner is Lecturer in Experimental Psychology at Sussex University, Brighton, England. (shrink)

Many existence propositions in constructive analysis are implied by the lesser limited principle of omniscience LLPO; sometimes one can even show equivalence. It was discovered recently that some existence propositions are equivalent to Bouwer's fan theorem FAN if one additionally assumes that there exists at most one object with the desired property. We are providing a list of conditions being equivalent to FAN, such as a unique version of weak König's lemma. This illuminates the relation between FAN and LLPO. Furthermore, (...) we give a short and elementary proof of the fact that FAN is equivalent to each positive valued function with compact domain having positive infimum. (shrink)

Working within Bishop’s constructive framework, we examine the connection between a weak version of the Heine–Borel property, a property antithetical to that in Specker’s theorem in recursive analysis, and the uniform continuity theorem for integer-valued functions. The paper is a contribution to the ongoing programme of constructive reverse mathematics.

The causal theory of action is widely recognized in the literature of the philosophy of action as the "standard story" of human action and agency--the nearest approximation in the field to a theoretical orthodoxy. This volume brings together leading figures working in action theory today to discuss issues relating to the CTA and its applications, which range from experimental philosophy to moral psychology. Some of the contributors defend the theory while others criticize it; some draw from historical sources while others (...) focus on recent developments; some rely on the tools of analytic philosophy while others cite the latest empirical research on human action. All agree, however, on the centrality of the CTA in the philosophy of action. The contributors first consider metaphysical issues, then reasons-explanations of action, and, finally, new directions for thinking about the CTA. They discuss such topics as the tenability of some alternatives to the CTA; basic causal deviance; the etiology of action; teleologism and anticausalism; and the compatibility of the CTA with theories of embodied cognition. Two contributors engage in an exchange of views on intentional omissions that stretches over four essays, directly responding to each other in their follow-up essays. As the action-oriented perspective becomes more influential in philosophy of mind and philosophy of cognitive science, this volume offers a long-needed debate over foundational issues.

It is shown, with intuitionistic logic, that if every locally constant function from to has a property akin to constancy, then the fan theorem for -bars holds, and conversely.

It is shown that, relative to Bishop-style constructive mathematics, the boundedness principle BD-N is equivalent both to a general result about the convergence of double sequences and to a particular one about Cauchyness in a semi-metric space.

We prove constructively that the weak König lemma and quantifier-free number-number choice imply that every pointwise continuous function from Cantor space into Baire space has a modulus of uniform continuity.

"The book closes with Pieper's thoughts on the permanent philosophical and theological significance of scholasticism and the Middle Ages. Once again, wearing his learning lightly, writing with a clarity that delights, Josef Pieper has taken the field from stuffier and more extended accounts."--BOOK JACKET.

Smart MR contrast agents exhibit modulation of their relaxivity by specific physiological or biochemical trigger-events, while targeted MR contrast agents are envisioned to deliver the large gadolinium chelates into the target tissue. In an effort to develop novel smart and targeted MR contrast agents, the series of the DO3A based multifunctional chelating agents with the variable length of the side chain has been synthesized. They serve as valuable multipurpose precursors for contrast agents based on gadolinium chelates in the design of (...) relaxometric MR probes. The presence of the amino group in the side chain of the macrocycle allows for conversion into various functional groups (aminophosponates, aminocarboxylates, etc.) or for conjugation with different biomolecules, dyes, and polymers. Choice of the functional groups depends on the.. (shrink)

El presente artículo propone el paradigma andino del “Vivir Bien” como alternativa al modelo económico, civilizatorio y social de un capitalismo neoliberal y depredador que manifiesta serias señales de crisis. Estas crisis se manifiestan en lo financiero, económico, político, axiológico y ecológico, de modo que se puede hablar de una “crisis civilizatoria”. El “Vivir Bien” andino es la expresión de una civilización opuesta en muchos aspectos al paradigma filosófico y civilizatorio de Occidente. Las contradicciones y tensiones entre los dos modelos (...) pueden verse, por ejemplo, en el proceso de cambio actual en Bolivia. (shrink)

This is a work by Josef Pieper, one of this century's most profound and lucid expositors of the thought of St. Thomas Aquinas.

We show constructively that every quasi-convex, uniformly continuous function \ with at most one minimum point has a minimum point, where C is a convex compact subset of a finite dimensional normed space. Applications include a result on strictly quasi-convex functions, a supporting hyperplane theorem, and a short proof of the constructive fundamental theorem of approximation theory.

Whilst the role of Maturation or M‐phase Promoting Factor (MPF) as a universal M‐phase regulator is well documented, much less attention has been paid to its role in nuclear transplantation experiments and especially to its influence upon remodelling of transplanted nuclei. There is currently wide acceptance that successful nuclear transplantation using differentiated nuclei is possible only in a cytoplasmic environment that is capable of inducing rapid nuclear de‐differentiation to a pronuclear‐like form. In this review our purpose is firstly, to outline (...) the conditions under which such remodelling can be induced, and secondly, to extend the debate to include a consideration of whether complete nuclear remodelling is an absolute necessity for clonal development.

This paper presents a computational model of emotions that is based in an appraisal theoretical framework. The model explores the dynamics of the appraisal–emotion relationship using parallel constraint satisfaction. It proposes belief coherence, desire coherence and belief–desire coherence as basic principles and specifies how these principles can be realised in a parallel constraint satisfaction system. The model shows that the very same mechanisms that account for the formation of coherence or consistency are also pivotal for the emergence and alteration of (...) emotional states and for the dynamics of the cognition–emotion relationship. Concrete simulation examples show how discrete emotions such as anger, pride, sadness, shame, surprise, relief and disappointment emerge out of these principles. (shrink)

Following conventional wisdom Theology as an academic discipline (taught at Universities) is something which developed only in the Middle Ages, or in a certain sense even as late as the 19th century. The present essay in contrast traces its origins to Classical Antiquity and outlines its development in early Christianity, especially with a view to institutions of higher education that existed in Late Antiquity, e. g. in rhetoric and philosophy. It concludes that there were forms of academic theological discourse in (...) Late Antiquity which were to become the basis of later developments in the discipline. (shrink)

The four essays in this little volume are the essence of a lifetime of thought, lecturing and writing by a leading twentieth century philosopher. Josef Pieper's theory of festivity was forged in dismal wartime Germany. Agreeing with Nietzsche that "the trick is not to arrange a festival but to find people who can enjoy it," he discovers a rage for anti-festival sweeping the earth: "C'est la guerre qui correspond a la fete!" Yet Pieper conveys 'certain tidings' of the divine (...) guarantee of the world and of human salvation. In each of these essays Dr. Pieper surveys twentieth century world views. In "Hope and History" he contrasts Baudelaire's and Dostoevsky's dire warnings of an extreme concentration of evil with the promise of the Apocalypse: victory over death; resurrection; a new heaven and a new earth. "The Unavoidable Dilemma of a Non-Christian Philosophy", he says, "is that while Plato, Pythagoras and Aristotle, the founders of Occidental philosophy, require an unprejudiced openness to theology, the secularized modern European or North American does not even know what 'wisdom in divine affairs' means." Finally, in "Leisure" he points out that in contemporary life utility demands to be the measure of all things, including 'spare time' and even the intellectual life of the university. However, Plato, like the Christians, says that only in celebrating divine worship does man lose the shape of a slave. (shrink)

A notion of resource‐bounded Baire category is developed for the classPC[0,1]of all polynomial‐time computable real‐valued functions on the unit interval. The meager subsets ofPC[0,1]are characterized in terms of resource‐bounded Banach‐Mazur games. This characterization is used to prove that, in the sense of Baire category, almost every function inPC[0,1]is nowhere differentiable. This is a complexity‐theoretic extension of the analogous classical result that Banach proved for the classC[0, 1] in 1931. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim).
