The research presented in this paper was motivated by our aim to study a problem due to J. Bourgain [3]. The problem in question concerns the uniform boundedness of the classical separation rank of the elements of a separable compact set of the first Baire class. In the sequel we shall refer to these sets (separable or non-separable) as Rosenthal compacta and we shall denote by ∝(f) the separation rank of a real-valued functionfinB1(X), withXa Polish space. Notice that in [3], (...) Bourgain has provided a positive answer to this problem in the case ofKsatisfyingwithXa compact metric space. The key ingredient in Bourgain's approach is that whenever a sequence of continuous functions pointwise converges to a functionf, then the possible discontinuities of the limit function reflect a local ℓ1-structure to the sequence (fn)n. More precisely the complexity of this ℓ1-structure increases as the complexity of the discontinuities offdoes. This fruitful idea was extensively studied by several authors (c.f. [5], [7], [8]) and for an exposition of the related results we refer to [1]. It is worth mentioning that A.S. Kechris and A. Louveau have invented the rank rND(f) which permits the link between thec0-structure of a sequence (fn)nof uniformly bounded continuous functions and the discontinuities of its pointwise limit. Rosenthal'sc0-theorem [11] and thec0-index theorem [2] are consequences of this interaction.Passing to the case where either (fn)nare not continuous orXis a non-compact Polish space, this nice interaction is completely lost.

Starting from the basic premises of Schank's notion of indexing in story telling and the representational approach of language, this paper investigates whether fairy tales create initial indexes for children, that may be re-indexed later in adult life, by reshaping their pre-existing experiences. More specifically, it focuses on the way fairy tales present several concepts already familiar to children, and whether this representation matches children’s pre-existing experiences. The data collected comes from several of Grimm Brothers' fairy tales and consists of (...) a corpus of 62839 word tokens. The fairy tales included were thematically related to general areas of everyday experience: femininity, blackness, whiteness, day, night, being young, ageing. The following semantically contradictory lexical pairs were examined in the expanded concordance, in relation to their collocations and semantic associations: old - young, woman - maiden, day - night, white - black. These were then compared with an adults’ and a children’s dictionary to check whether the collocations, semantic associations of the selected words as portrayed in the data, matched the societally accepted meanings found in dictionaries. The comparison indicated that, although the connotative meanings were included in the majority of denotative meanings that make up words' definitions in the adult dictionary examined, only five of them matched the connotative meanings of the words examined in the data. On the other hand, the way the above concepts/words were presented in the children’s dictionary, was very simple, probably reflecting children’s experiences. It seems, thus, that the concepts - at least some of them - presented in the fairy tales examined, do not “officially” relate to children's but to adults' experiences, functioning as an index that re-shapes children’s pre-existing concepts.

Since its publication in French in 1949 by the Presses Universitaires de France, Basil Tatakis' Byzantine Philosophy remains the sole work of its kind, an analysis of the rise of Christianity in the East and the civilization that grew out of it at the crossroads of Europe, Asia, and Africa.

With the earliest known reference to angling with a fly dating from the Chou Dynasty, more than 2,300 years ago, it should come as no surprise that when asked to justify their passionate devotion to fly fishing, many anglers will refer to the rich and venerable literature the sport has generated. Ranging from Plutarch's references to Nile fishing in the Life of Antonius, to Pliny the Elder's Historia Naturalis, to the fifteenth century classic, Dame Julian Berner's The Treatyse of Fysshynge (...) wyth an Angle, to the sport's bible, the 17th century The Compleat Angler by Izaak Walton, to literary treatments in the work of authors such as John Donne, Gerard Manley Hopkins, William Butler Yeats, Ezra Pound and Ernest Hemingway, the wealth of literature devoted to fly fishing appears to be out of proportion to what is, ultimately, just a way of seducing an animal with a brain the size of a pea into inhaling a hook upon which some feathers, furs and tinsels have been lashed. What then, one may legitimately ask, is it about this sport that creates fanatical devotion on the part of its practitioners, who tend to regard it with such zeal and passion as is commonly reserved for art and religion?

One of the more recalcitrant issues in the philosophy of time concerns the question of temporal asymmetry. Some theorists, many of them, like Einstein, physicists, believe that time is fundamentally reversible. According to this view, the physical universe is indifferent to the direction of time; consequently, something like an arrow of time is held to be a human subjective imposition on an otherwise temporally isotropic world. Another position, held by Alfred North Whitehead and contemporary process philosophers, maintains that temporal asymmetry (...) is a primitive condition of the universe, and that therefore even the most basic physical processes, such as those occurring at the subatomic level, display a distinct temporal direction. Finally, the philosopher of time J.T. Fraser (1978) claims that temporal asymmetry is an emergent feature of the universe, appearing for the first time with biogenesis. According to Fraser, with the emergence of life comes a present, or “now”, a temporal dimension whose absence in more primitive levels of cosmic evolution prohibits the attribution of an arrow of time to any pre-biotic entity.

This study examines how authentic leadership influences team performance via the mediating mechanism of team reflexivity. Adopting a self-regulatory perspective, we propose that authentic leadership will predict the specific team regulatory process of reflexivity, which in turn will be associated with two outcomes of team performance, effectiveness and productivity. Using survey data from 53 teams in three organizations in the United Kingdom and Greece and controlling for collective trust, we found support for our stated hypotheses with the results indicating a (...) significant fully mediated relationship. As predicted the self-regulatory behaviors inherent in the process of authentic leadership served to collectively shape team behavior, manifesting in the process of team reflexivity, which, in turn, positively predicted team performance. We conclude with a discussion of how this study extends theoretical understanding of authentic leadership in relation to teamwork and delineate several practical implications for leaders and organizations.

First published in 1986, Knowledge, Belief, and Witchcraft remains the only analysis of indigenous discourse about an African belief system undertaken from within the framework of Anglo-American analytical philosophy. Taking as its point of departure W. V. O. Quine's thesis about the indeterminacy of translation, the book investigates questions of Yoruba epistemology and of how knowledge is conceived in an oral culture.

This chapter first surveys general issues in the epistemic internalism / externalism debate: what is the distinction, what motivates it, and what arguments can be given on both sides. -/- The second part of the chapter will examine the internalism / externalism debate as regards to the specific case of the epistemology of memory belief.

The acquisition of a new skill usually proceeds through five stages, from novice to expert, with a sixth stage of mastery available for highly motivated performers. In this chapter, we re-state the six stages of the Dreyfus Skill Model, paying new attention to the transitions and interrelations between them. While discussing the fifth stage, expertise, we unpack the claim that, “when things are proceeding normally, experts don’t solve problems and don’t make decisions; they do what normally works” (Dreyfus & Dreyfus, (...) 1988, pp. 30 – 31). This leads us to offer an account of the “perspectival deliberation” that arises for experts and masters and that is distinct from the calculative deliberation characteristic of the lower stages of skillfulness.

What are the most fundamental features of the world? Do minds stand outside the natural order? Is a unified picture of mental and physical reality possible? The Mind in Nature provides a staunchly realist account of the world as a unified system incorporating both the mental and the physical. C. B. Martin, an original and influential exponent of 'ontologically serious' metaphysics, echoes Locke's dictum that 'all things that exist are only particulars', and argues that properties are powerful qualities. He also (...) spells out the implications of this view for philosophical conceptions of causation, intentionality, consciousness, and the mind-body problem. Martin emphasizes the importance of non-conscious 'vegetative' systems, which provide clear examples of intentionality in the form of representational use. The slide from representational use to consciousness involves a change in the material of use, but not the form of representation. A concluding chapter provides an argument for the view that an ontology of particular substances and properties leads ineluctably to monism: the bus we board with Locke takes us directly to the world of Spinoza and Einstein. Along the way, we are led to understand the nature of minds and conscious states of mind in a way that avoids both reductionism and dualism. (shrink)

We presuppose a position of scientific realism to the effect (i) that the world exists and (ii) that through the working out of ever more sophisticated theories our scientific picture of reality will approximate ever more closely to the world as it really is. Against this background consider, now, the following question: 1. Do the empirical theories with the help of which we seek to approximate a good or true picture of reality rest on any non-empirical presuppositions? One can answer (...) this question with either a 'yes' or a 'no'. 'No' is the preferred answer of most contemporary methodologists -- Murray Rothbard is one distinguished counterexample to this trend -- who maintain that empirical theories are completely free of non-empirical ('a priori') admixtures and who see science as a matter of the gathering of pure 'data' obtained through simple observation. From such data scientific propositions are then supposed to be somehow capable of being established. (shrink)

Is there a limit to the legitimate demands of morality? In particular, is there a limit to people's responsibility to promote the well-being of others, either directly or via social institutions? Utilitarianism admits no such limit, and is for that reason often said to be an unacceptably demanding moral and political view. In this original new study, Murphy argues that the charge of excessive demands amounts to little more than an affirmation of the status quo. The real problem with utilitarianism (...) is that it makes unfair demands on people who comply with it in our world of nonideal compliance. Murphy shows that this unfairness does not arise on a collective understanding of our responsibility for others' well being. Thus, according to Murphy, while there is no general problem to be raised about the extent of moral demands, there is a pressing need to acknowledge the collective nature of the demands of beneficence.

In this concise yet powerful book, one of the twentieth century's most respected political philosophers presents a controversial reassessment of the political ideas and intellectual legacy of Edmund Burke. A practicing politician and powerful writer, full of ideas, Burke was intent on getting those ideas translated into government policies. But he was too much the impatient practitioner to set out his principles in a single book in the manner of Locke or Hume, leaving both admirers and opponents ample scope to (...) reinterpret his work in different ways. Macpherson, however, finds Burke's views on political economy to be the one consistent factor in his thinking. Today Burke is often viewed as one of modern conservatism's founding lights, and in an era of global capitalism unfettered by national borders, Macpherson's reassessment of Burke's ideas is perhaps more timely than ever.
