Plato's "Ion," despite its frail frame and traditionally modest status in the corpus, has given rise to large exegetical claims. Thus some historians of aesthetics, reading it alongside page 205 of the Symposium, have sought to identify in it the seeds of the post-Kantian notion of 'art' as non-technical making, and to trace to it the Romantic conception of the poet as a creative genius. Others have argued that, in the "Ion," Plato has Socrates assume the existence of a technē (...) of poetry. In this article, these claims are challenged on exegetical and philosophical grounds. To this effect, Plato's use of poiētēs and poiēsis in the Symposium is analysed, the defining criteria of technē in the "Ion" and other dialogues are identified and discussed, and the 'Romantic' interpretation of the dialogue is traced to Shelley's tendentious translation of it. These critical developments lead to what is presented as a more faithful reading of the dialogue. In the "Ion," it is claimed, Plato seeks to subvert the traditional status of poetry by having Socrates argue that poetry is both non-rational and non-cognitive in nature. In the third part of the article, suggestions are offered as to the contribution made by the "Ion" to the evolution of Plato's reflections on poetic composition, and particularly as to the reasons which later induced Plato to substitute the concept of mimesis for that of inspiration in his account of poetry.

The status of beauty in Plotinus' metaphysics is unclear: is it a Form in Intellect, the Intelligible Principle itself, or the One? Basing themselves on a number of well-known passages in the "Enneads," and assuming that Plotinus' Forms are similar in function and status to Plato's, many scholars hold that Plotinus theorized beauty as a determinate entity in Intellect. Such assumptions, it is here argued, lead to difficulties over self-predication, the interpretation of Plotinus's rich and varied aesthetic terminology and, most (...) of all, the puzzling dearth of references, in the whole of the "Enneads," to a Form of Beauty. A detailed reading of VI.7.32 and 33 reveals that, in these two crucial passages at least, Plotinus adopts an aesthetic approach to the One and that, far from confining Beauty to Intellect, he equates the One, the Good and the Beautiful. This reading is here supported not only by an analysis of the text but also by a consideration of the semantic differences between μορφή and ε[unrepresentable symbol]δος, the inter-relatedness, in Plotinus' philosophy, of the concepts of love and value, and the exclusion of beauty from the πρ[unrepresentable symbol]τα γένη. In turn, the exegesis of VI.7.32 and 33 raises the issue of the significance for aesthetics understood in the narrow sense of the word, of Plotinus's ontology of beauty. It is here claimed that in so far as sensible beauty, both artistic and natural, can be nothing else than an effect of the shaping action of the Forms and a reflection of their radiance, singular or global, it should not be held that Plotinus had an aesthetics in the modern sense of this term.

ABSTRACTStudies examining the interpretation that is given to if–then statementstypically use what are referred to as basic conditionals, which give contextless relations between two unrelated concrete terms. However, there is some evidence that basic conditionals require a more abstract form of representation. In order to examine this, we presented participants with truth-table tasks involving either basic conditionals or conditionals referring to imaginary categories, and standard conditional inference tasks with abstract and familiar premises. As expected, fewer typical defective conditional interpretations were (...) given to basic conditionals. In addition, partial correlations showed a unique relationship between the interpretation of basic conditionals and abstract inferential reasoning. Results suggest that people process basic conditionals as a form of abstract reasoning, and that the interpretation of conditionals... (shrink)

We discuss the interplay between the axiomatic and the semantic approach to truth. Often, semantic constructions have guided the development of axiomatic theories and certain axiomatic theories have been claimed to capture a semantic construction. We ask under which conditions an axiomatic theory captures a semantic construction. After discussing some potential criteria, we focus on the criterion of ℕ-categoricity and discuss its usefulness and limits.

The volume concludes by examining a critique of Hegel's metaphysical position from the perspective of the "continental" tradition, and in particular Gilles ...

This article considers distinct ways of understanding the world, referred to in psychology as Functions of Consciousness or as Cognitive Modes, having as the scope of interest epistemology and natural sciences. Inspired by C.G. Jung's Simile of the Spectrum, we consider three basic cognitive modes associated to: (R) embodied instinct, experience, and action; (G) reality perception and learning; and (B) concept abstraction, rational thinking, and language. RGB stand for the primary colors: red, green, and blue. Accordingly, a conceptual map between (...) cognitive modes and primary and secondary colors is built based on the physics and physiology of color perception and epistemological characteristics of the aforementioned cognitive modes, leading to logical relations structured as an Hexagon of Opposition. Finally, this model of cognitive modes is applied to the analysis and interpretation of some important episodes in the historical development of physics and technology. (shrink)

The main goal of this article is to use the epistemological framework of a specific version of Cognitive Constructivism to address Piaget’s central problem of knowledge construction, namely, the re-equilibration of cognitive structures. The distinctive objective character of this constructivist framework is supported by formal inference methods of Bayesian statistics, and is based on Heinz von Foerster’s fundamental metaphor of objects as tokens for eigen-solutions. This epistemological perspective is illustrated using some episodes in the history of chemistry concerning the definition (...) or identification of chemical elements. Some of von Foerster’s epistemological imperatives provide general guidelines of development and argumentation. (shrink)

In this paper epistemological, ontological and sociological questions concerning the statistical significance of sharp hypotheses in scientific research are investigated within the framework provided by Cognitive Constructivism and the FBST (Full Bayesian Significance Test). The constructivist framework is contrasted with the traditional epistemological settings for orthodox Bayesian and frequentist statistics provided by Decision Theory and Falsificationism.

[INTRODUCTION] Like the terms 'dialectic', 'Aufhebung' (or 'sublation'), and 'Geist', the term 'concrete universal' has a distinctively Hegelian ring to it. But unlike these others, it is particularly associated with the British strand in Hegel's reception history, as having been brought to prominence by some of the central British Idealists. It is therefore perhaps inevitable that, as their star has waned, so too has any use of the term, while an appreciation of the problematic that lay behind it has seemingly (...) vanished: if the British Idealists get any sort of mention in a contemporary metaphysics book (which is rarely), it will be Bradley's view of relations or truth that is discussed, not their theory of universals, so that the term has a rather antique air, buried in the dusty volumes of Mind from the turn of the nineteenth century. This is not surprising: the episode known as British Idealism can appear to be a period that is lost to us, in its language, points of historical reference (Lotze, Sigwart, Jevons), and central preoccupations (the Absolute). Even while interest in Hegel continues to grow, interest in his Logic has grown more slowly than in the rest of his work, with Book III of the Logic remaining as the daunting peak of that challenging text - while it is here that the British Idealists focussed their attention and claimed to have uncovered that 'exotic' but 'vanished specimen', the concrete universal. Finally, as the trend of reading Hegel pushes ever further in a non-metaphysical direction, it might be thought that the future of the concrete universal is hardly likely to be brighter than its recent past - for it may seem hard to imagine how a conception championed by the British Idealists, who were apparently shameless in their metaphysical commitments, can find favour in these more austere and responsible times. In this paper, however, I want to make a case for holding that there is something enlightening to be found in how some of the British Idealists approached the 'concrete universal', both interpretatively and philosophically. At the interpretative level, I will argue that while not everything these Idealists are taken to mean by the term is properly to be found in Hegel, their work nonetheless relates to a crucial and genuine strand in Hegel's position, so that their discussion of this issue is an important moment in the reception history of his thought. At a philosophical level, I think that the question that concerned Hegel and these British Idealists retains much of its interest, as does their shared approach to it: namely, how far does our thought involve a mere abstraction from reality, and what are the metaphysical and epistemological implications if it turns out it does not? As such, I will suggest, taking seriously what these British Idealists have to say about the concrete universal can help us both in our understanding of Hegel, and in our appreciation of the contribution Hegel's position can make to our thinking on the issues that surround this topic.

In this article, I want to argue that scepticism for Kant must be seen in ancient and not just modern terms, and that if we take this into account we will need to take a different view of Kant's response to Hume from the one that is standardly presented in the literature. This standard view has been put forward recently by Paul Guyer, and it is therefore his view that I want to look at in some detail, and to try (...) to correct. (shrink)

This is an introduction to a special issue of the British Journal for the History of Philosophy, on the relation between idealism and pragmatism. It sets out the way in which the two traditions can be related, and then outlines the papers contained in the special issue.

In this second and last paper of the two part investigation on "Modality and Axiomatic Theories of Truth" we apply a general strategy for constructing modal theories over axiomatic theories of truth to the theory Kripke-Feferman. This general strategy was developed in the first part of our investigation. Applying the strategy to Kripke-Feferman leads to the theory Modal Kripke-Feferman which we discuss from the three perspectives that we had already considered in the first paper, where we discussed the theory Modal (...) Friedman-Sheard. That is, we first show that Modal Kripke-Feferman preserves theoremhood modulo translation with respect to modal operator logic. Second, we develop a modal semantics fitting the newly developed theory. Third, we investigate whether the modal predicate of Modal Kripke-Feferman can be understood along the lines of a proposal of Kripke, namely as a truth predicate modified by a modal operator.

The paper maps out and responds to some of the main areas of disagreement over the nature of Wittgenstein’s philosophy: (1) Between defenders of a “two Wittgensteins” reading (which draws a sharp distinction between early and late Wittgenstein) and the opposing “one Wittgenstein” interpretation. (2) Among “two-Wittgensteins” interpreters as to when the later philosophy emerged, and over the central difference between early and late Wittgenstein. (3) Between those who hold that Wittgenstein opposes only past philosophy in order to do philosophy (...) better and those who hold that Wittgenstein aimed to bring an end to philosophy and teach us to get by without a replacement. It is shown that each of these debates depends on some deeply un-Wittgensteinian, and quite mistaken, assumptions. It is concluded that Wittgenstein’s most polished writing, most notably in Philosophical Investigations I §§ 1–425, is best understood as a kind of Pyrrhonism which aims to subvert philosophical theorizing, by means of a polyphonic dialogue. Because this delicate balance between philosophical questions and their dissolution is not achieved in most of his other published and unpublished writings, we should be very cautious when using the theories and methods we find in those other writings as a guide to reading the Philosophical Investigations.

In this investigation we explore a general strategy for constructing modal theories where the modal notion is conceived as a predicate. The idea of this strategy is to develop modal theories over axiomatic theories of truth. In this first paper of our two part investigation we develop the general strategy and then apply it to the axiomatic theory of truth Friedman-Sheard. We thereby obtain the theory Modal Friedman-Sheard. The theory Modal Friedman-Sheard is then discussed from three different perspectives. First, we (...) show that Modal Friedman-Sheard preserves theoremhood modulo translation with respect to modal operator logic. Second, we turn to semantic aspects and develop a modal semantics for the newly developed theory. Third, we investigate whether the modal predicate of Modal Friedman-Sheard can be understood along the lines of a proposal of Kripke, namely as a truth predicate modified by a modal operator.

We present SASC, Self-Adaptive Semantic Crossover, a new class of crossover operators for genetic programming. SASC operators are designed to induce the emergence and then preserve good building-blocks, using metacontrol techniques based on semantic compatibility measures. SASC performance is tested in a case study concerning the replication of investment funds.

: This paper offers a distinctive interpretation of Hegel's Doppelsatz from the Preface to the Philosophy of Right: 'What is rational is actual; and what is actual is rational'. This has usually been interpreted either conservatively (as claiming that everything that is, is right or good) or progressively (that if the world were actual, it would be right or good, but that there is a distinction that can be drawn between existence and actuality). My aim in this paper is to (...) argue against both interpretations, so that the position I offer is neutral between the two. My claim is that when Hegel identifies what is actual with what is rational in the Doppelsatz, his intention is not to offer a normative assessment of what is actual; rather, it is to suggest that genuine philosophy must be committed to reason in its methods of inquiry, if it is to properly undertake an investigation into the "spiritual universe" as well as the "natural" one. The Doppelsatz is thus a defence of philosophical rationalism, rather than a normative claim about "was ist wirklich". (shrink)

Wittgenstein’s writings and lectures during the first half of the 1930s play a crucial role in any interpretation of the relationship between the Tractatus and the Philosophical Investigations . G. E. Moore’s notes of Wittgenstein’s Cambridge lectures, 1930-1933, offer us a remarkably careful and conscientious record of what Wittgenstein said at the time, and are much more detailed and reliable than previously published notes from those lectures. The co-authors are currently editing these notes of Wittgenstein’s lectures for a book to (...) be published by Cambridge University Press. We describe the materials that make up Moore’s notes, explain their unique value, review the principal editorial challenges that these materials present, and provide a brief outline of our editorial project.

The paper proposes a strategy for understanding metaphysical grounding in deflationary terms and, more generally, proposes a form of methodological deflationism with respect to the notions of ground. The idea is to define a deflationary is grounded in-predicate by appeal to the two-place non-causal connective ‘because’ and a deflationary truth predicate. To this end, we discuss the explanatory role of the truth-predicate in non-causal explanations and develop a theory of truth for the language of the ‘because’-connective. We argue that at (...) least from a logical perspective our deflationary notion of ground is up to the task. (shrink)

"Interpreting Hegel means taking a stand on all the philosophical, political and religious problems of our century." Merleau-Ponty G. W. F. Hegel (1770-1831), arguably the greatest philosopher of the nineteenth century, decisively influenced the direction of all subsequent European thought. He has been interpreted variously as a theist and an atheist, a conservative and a liberal, an essentialist and a proto-existentialist, a rationalist and an irrationalist. In all the areas he covered, Hegel sought a new form of understanding that had (...) eluded his predecessors but which he believed was necessary for mankind to once again find itself "at home in the world." This collection of works on Hegel reflects the many-sided nature of Hegel's reception from 1831 onwards, and offers critical studies on the full range of his work. The four volumes incorporate the classic readings of Hegel, from both the continental and analytic traditions, and also include the central twentieth-century readings influenced by developments in European thought which reappraise his work. These volumes offer a unique perspective on Hegel by revealing how our understanding of him is influenced by historical readings of his work. Each volume provides a clear and helpful introduction which sets the articles in their historic context and highlights the central philosophical issues they raise. (shrink)

We study Compositional Models based on Dirichlet Regression where, given a (vector) covariate x, one considers the response variable, y, to be a positive vector with a conditional Dirichlet distribution, y | X We introduce a new method for estimating the parameters of the Dirichlet Covariate Model given a linear model on X, and also propose a Bayesian model selection approach. We present some numerical results which suggest that our proposals are more stable and robust than traditional approaches.

Intentional sampling methods are non-probabilistic procedures that select a group of individuals for a sample with the purpose of meeting specific prescribed criteria. Intentional sampling methods are intended for exploratory research or pilot studies where tight budget constraints preclude the use of traditional randomized representative sampling. The possibility of subsequently generalize statistically from such deterministic samples to the general population has been the issue of long standing arguments and debates. Nevertheless, the intentional sampling techniques developed in this paper explore pragmatic (...) strategies for overcoming some of the real or perceived shortcomings and limitations of intentional sampling in practical applications.

Since September 11th, we frequently hear that political differences should be put aside: the real struggle is between good and evil. What does this mean for political and social life? Is there a 'Third Way' beyond left and right, and if so, should we fear or welcome it? This thought-provoking book by Chantal Mouffe, a globally recognized political author, presents a timely account of the current state of democracy, affording readers the most relevant and up-to-date information. Arguing that liberal (...) 'third way thinking' ignores fundamental, conflicting aspects of human nature, Mouffe states that, far from expanding democracy, globalization is undermining the combative and radical heart of democratic life. Going back first to Aristotle, she identifies the historical origins of the political and reflects on the Enlightenment, and the social contract, arguing that in spite of its good intentions, it levelled the radical core of political life. Contemporary examples, including the Iraq war, racism and the rise of the far right, are used to illustrate and support her theory that far from combating extremism, the quest for consensus politics undermines the ability to challenge it. These case studies are also highly effective points of reference for student revision. _On the Political _is a stimulating argument about the future of politics and addresses the most fundamental aspects of democracy that will aid further study.

This paper examines a number of river images which have been attributed to Heraclitus, the ways they are used by Plato and Wittgenstein, and the connection between these uses of imagery and the metaphilosophical issues about the nature and limits of philosophy which they lead to. After indicating some of the connections between Heraclitus’, Plato’s and Wittgenstein’s use of river images, I give a preliminary reading of three crucial fragments from the Heraclitean corpus, associating each with a different river image. (...) Each of these images implies an overall conception of the nature of change and continuity and of the relationship between language and world. I then turn to the use of these images by Plato and Wittgenstein, and explore the relationship between their uses of river imagery and their conceptions of philosophy. To put it slightly differently, this paper is about Plato’s and Wittgenstein’s use of certain Heraclitean ideas. (shrink)

The central question in this paper is the following: how does Nietzsche use history in his critique of morality? The answer, in sum: interestingly, not how you (i.e. most Nietzsche scholars) think, and not well enough. My focus is on The Antichrist, not his Genealogy of Morality, which is more commonly used to answer this question. And I look, in particular, at Nietzsche’s use of good, contemporary scholarship on the origins of Judaism. The chapter also examines the so-called 'genetic fallacy', (...) arguing that Nietzsche has a provisional response to it, but that this response leads to further complications. (shrink)

This article presents a two level hierarchical forecasting model developed in a consulting project for a Brazilian magazine publishing company. The first level uses a VARMA model and considers econometric variables. The second level takes into account qualitative aspects of each publication issue, and is based on polynomial networks generated by Genetic Programming (GP).

This paper shows how an efficient and parallel algorithm for inference in Bayesian Networks (BNs) can be built and implemented combining sparse matrix factorization methods with variable elimination algorithms for BNs. This entails a complete separation between a first symbolic phase, and a second numerical phase.

The data analyzed in this paper are part of the results described in Bueno et al. (2000). Three cytogenetics endpoints were analyzed in three populations of a species of wild rodent – Akodon montensis – living in an industrial, an agricultural, and a preservation area at the Itajaí Valley, State of Santa Catarina, Brazil. The polychromatic/normochromatic ratio, the mitotic index, and the frequency of micronucleated polychromatic erythrocites were used in an attempt to establish a genotoxic profile of each area. It (...) was assumed that the three populations were in the same conditions with respect to the influence of confounding factors such as animal age, health, nutrition status, presence of pathogens, and intra- and inter-populational genetic variability. Therefore, any differences found in the endpoints analyzed could be attributed to the external agents present in each area. The statistical models used in this paper are mixtures of negative-binomials and Poisson variables. The Poisson variables are used as approximations of binomials for rare events. The mixing distributions are beta densities. The statistical analyzes are under the bayesian perspective, as opposed to the frequentist ones often considered in the literature, as for instance in Bueno et al. (2000). (shrink)

To estimate causal relationships, time series econometricians must be aware of spurious correlation, a problem first mentioned by Yule (1926). To deal with this problem, one can work either with differenced series or multivariate models: VAR (VEC or VECM) models. These models usually include at least one cointegration relation. Although the Bayesian literature on VAR/VEC is quite advanced, Bauwens et al. (1999) highlighted that “the topic of selecting the cointegrating rank has not yet given very useful and convincing results”. The (...) present article applies the Full Bayesian Significance Test (FBST), especially designed to deal with sharp hypotheses, to cointegration rank selection tests in VECM time series models. It shows the FBST implementation using both simulated and available (in the literature) data sets. As illustration, standard non informative priors are used. (shrink)
