Recently, philosophers have come forth with approaches to chemistry based on its actual practice, imparting to it a proper aim and character of its own. These approaches add to the currently growing movement of pluralist philosophies of science. We draw on recent pluralist accounts from chemistry and analyse three notions from modern chemical practice and theory in terms of these accounts, in order to complement the so far more general pluralist approaches with specific evidence. Our survey reveals that the concept (...) of element indicates conceptual pluralisms in chemistry. that electronegativity illustrates methodological pluralism in determining one and the same concept, and that acidity is an instance of plurality hidden behind ‘one notion’.

Electronegativity is a quantified, typical chemical concept, which correlates the ability of chemical species to attract electrons during their contact with other species with measurable quantities such as dissociation energies, dipole moments, ionic radii, ionization potentials, electron affinities and spectroscopic data. It is applied to the description and explanation of chemical polarity, reaction mechanisms, other concepts such as acidity and oxidation, the estimation of types of chemical compounds and periodicity. Although this concept is very successful and widely used, and in (...) spite of the fact that it is still subject to scientific investigations, neither a more than intuitive definition nor a generally accepted, logically clear and standardized quantification model has been developed. In the present work, electronegativity is presented and discussed with respect to its main conceptual and operational continuities and discontinuities. We try to analyze the epistemological status of electronegativity, conceived as a typical notion of chemical sciences. Under ‘epistemological status’ we subsume the issues of its reference, its historical persistence, and the relationship between its measurement and quantification. (shrink)

Immanuel Kant has built up a dualistic epistemology that seems to fit to the peculiarities of chemistry quite well. Friedrich Paneth used Kant’s concept and characterised simple and basic substances which refer to the empirical and to the transcendental world, respectively. This paper takes account of the Kantian influences in Paneth’s philosophy of chemistry, and discusses pertinent topics, like observables, atomism and realism.

The eminent radiochemist Friedrich Paneth (1887–1958) tried to come to terms with the following epistemological problem: On the one hand chemical elements are characterized empirically as indestructible material species, on the other hand they are characterized theoretically as having the same number of protons in the nuclei of their atoms. Paneth used the dualistic Kantian epistemology (using Eduard von Hartmann's interpretation) in order to describe the combination of these two aspects, applying the terms “Grundstoff”, fundamental matter, to the latter and (...) “einfacher Stoff”, simple matter, to the former. The present paper discusses the applicability of Kant's philosophy – in the interpretation of Paneth – to the (modern) philosophy of chemistry. (shrink)

In this short essay I address the central topic of the Centenary Workshop on Acidity, that is the relations of the classical protonist acid–base theory by Brønsted and the electronist approach by Lewis. Emphasis is laid on the empirical background of both approaches and the over-theoretization of chemical phenomena (essentialism) is criticized.

Dies ist eine der wenigen umfassenden Monographien zur Philosophie der großen Naturwissenschaft Chemie auf dem aktuellen Stand der seit etwa drei Jahrzehnten aufblühenden wissenschaftsphilosophischen Teildisziplin. Es wird untersucht, wie die zentralen Aspekte Stofflichkeit, Analyse, Synthese, Kompositionismus, Potentialität, Affinität, Reaktivität, Temporalität, Atomismus, Individuen, Arten, Bindungstheorie, Unterbestimmtheit, und Pluralismus in der Chemie zusammenhängen. Die These wird vertreten, dass es der Chemie keinerlei Abbruch hinsichtlich ihrer wissenschaftlichen Bedeutung tut, sie mit Kant als „systematische" Kunst anzusehen. Vielmehr besteht sogar Anlass, sich mit einer gleichsam (...) „metachemischen" Grundhaltung von den Unzulänglichkeiten herkömmlicher Wissenschaftstheorie zu lösen. Das Buch ist die Bilanz von Bemühungen des Autors in der Chemiephilosophie in den genannten drei Jahrzehnten. (shrink)

After a brief biography of Jaap van Brakel we set out his appropriation and use of the distinction between the manifest image and the scientific image of the world. In a certain sense van Brakel gives priority to the manifest image as the ultimate source of meaning in chemical discourses. He does not take sides in the debate about nominal and real essences, twin earths and so, but presents a compromise. As an active practitioner of the chemical arts he emphasises (...) the indispensability of models as a main tool for chemical thinking. We then turn to van Brakel’s interest in forging an intercultural point of view in which philosophy of chemistry plays an important part. (shrink)

Models of cognitive vulnerability claim that depressive symptoms arise as a result of an interaction between negative affect and cognitive reactions, in the form of dysfunctional attitudes and negative inferential style. We present a model that complements this approach by focusing on the appraisal processes that elicit and differentiate everyday episodes of emotional experience, arguing that individual differences in appraisal patterns can foster negative emotional experiences related to depression (e.g., sadness and despair). In particular, dispositional appraisal biases facilitating the elicitation (...) of these emotions more frequently and more intensely. This, in turn, is likely to have a negative influence on cognitive processing and emotion regulation in general. (shrink)

In _The Idealism of Freedom_, Klaus Vieweg argues for a Hegelian turn in philosophy: Hegel’s idealism of freedom contains a number of epoch-making ideas that articulate a new understanding of freedom, which still shape contemporary philosophy.

Die Arbeiten der Künstler Paul Cézanne, Paul Klee und Wassily Kandinsky werden in diesem Band phänomenologisch betrachtet. Auf je eigene Weise vollzieht jeder von ihnen eine Wendung im Kunstverständnis. Bezeichnend dafür ist Klees berühmter Satz von 1920: »Die Kunst gibt nicht das Sichtbare wieder, sondern macht sichtbar.« Klaus Kienzler untersucht an exemplarischen Werken, auf welche Weise sich die drei Maler mit philosophischen Grundthemen wie Zeit und Bewegung auseinandergesetzt haben. Zugleich geht es ihm darum auszuloten, inwieweit phänomenologische Ansätze (Heidegger, Welte, (...) Fink, Rombach, Merleau-Ponty) Malerei der klassischen Moderne zu erhellen vermögen. (shrink)

English translation by Kneller and Losonsky of Klaus Reich, Die Vollständigkeit der Kantischen Urteilstafel -/- "This classic of Kant scholarship, whose first edition appeared in 1932, deals with one of the most controversial and difficult topics in the Critique of Pure Reason: Kant's table of judgments and their connection to the table of categories. Kant's attempt to derive the latter from the former is called the "Metaphysical Deduction," and it paves the way for the Transcendental Deduction that is universally (...) recognized as the heart of the Critique." "Many commentators have passed over the Metaphysical Deduction in silence, as if embarrassed by Kant's fatuity, and his critics are almost unanimous in finding its premise ungrounded, its argument incorrect, and its conclusion false. At the heart of the failure of the Metaphysical Deduction, it is alleged, is Kant's inability to justify the table of the forms of judgment. Critics argue that Kant simply took these forms of judgment from the logic textbooks of his day and doctored them so as to yield the required categories. Such objections were current even in Kant's time; they were repeated by Hegel, and are commonplaces of Kant criticism today." "This book is the fullest and most systematic evaluation ever made of the Metaphysical Deduction. Reich argues that its principal conclusion is correct even though Kant failed to establish it in the Metaphysical Deduction proper, and he defends the conclusion by using Kant material far removed from the text of the Metaphysical Deduction, notes by Kant that only became available in the 1920's and that remain even now untranslated into English. With the publication of this translation for English-speaking Kant scholars, a neglected and impugned part of the Critique of Pure Reason can finally receive the attention it deserves."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Images are objects of work in the laboratory. On its face, this work is achieved through talk Yet the talk attached to these images makes reference to other images, which are drawn from varcous environments. In this article, four such environments are identified: the domain of laboratory practice; the context of invisible physical reactions; the future image as it will appear in publication; and the domain of case precedents and reference scenarios from the field. The work of image analysis brings (...) the outside of the image into it and takes the inside out. Thus it can be seen that images are not just taken, they are designed and made. (shrink)

Positive and negative feelings were central to the development of economics, especially in utility theory in classical economics. While neoclassical utility theory ignored feelings, behavioral economics more recently reintroduced feelings in utility theory. Beyond feelings, economic theorists use full-fledged specific emotions to explain behavior that otherwise could not be understood or they study emotions out of interest for the emotion itself. While some analyses display a strong overlap between psychological thinking and economic modelling, in most cases there is still a (...) large gap between economic and psychological approaches to emotion research. Ways how to reduce this gap are discussed. (shrink)

The chromosomes which segregate in anaphase I of meiosis are usually physically bound together through chiasmata. This association is necessary for proper segregation, since univalents sort independently from one another in the first meiotic division and this frequently leads to genetically unbalanced offspring. There are, however, a number of species where genetic exchanges in the form of meiotic cross‐overs, the prerequisite of the formation of chiasmata, are routinely missing in one sex or between specific chromosomes. These species nevertheless manage to (...) segregate these non‐exchange chromosomes. There are four direct modes for associating achiasmatic chromosomes: (a) modified SC, (b) adhesion of chromatids comparable to somatic pairing, (c) ‘stickiness’ of heterochromatin or (d) specific ‘segregation bodies’, consisting of material structurally different from chromatin. There is also the possibility that the spindlepossibly joining forces with the kinetochores‐carries out the faithful segregation of univalents which are not directly physically attached to one another. Finally, amphitelic orientation of univalents in metaphase I and pairing of the chromatids in meiosis II appear to ensure correct segregation as well. (shrink)

Here I try a new synthesis of personalism and materialism leading to new concepts of sense. Beginnig with the analysis of the correlations between matter, personality, language, understanding, cognition, knowledge, and the problem of truth, followed by a critique of pragmatism, personalism and "new realism" as well as by ontological concretisations in different fields of philosophy, i.e. in logical order from cosmology to anthropology, ethics, history and political philosophy (including globalization, digital revolution amd ecocide), aesthetics, and philosophy of religion, leading (...) to new concepts of sense and value. Of immediate political relevance is my new concept of a democratic eco-socialism, drawing conclusions of the failure of the socialist experiences in the world up to nowadays. Not giving up the Marxian vision of a realm of Freedom, Justice and Solidarity, that of a "free association of free individuals". (shrink)

In his commentary on Aristotle’s Peri hermeneias,1 Abelard distinguishes the form of an expression2 (oratio) from what it says, that is, its content. The content of an expression is its understanding (intellectus). This distinction is surely the most well-known and central idea in Abelard’s commentary. It provides him with the opportunity to distinguish statements (enuntiationes) from other kinds of expressions without implying a diference in their content, since the ability of a statement to signify something true or false (verum vel (...) falsum)3 cannot be found in its content. More precisely, Abelard distinguishes statements both from complete expressions (orationes perfectae) that are not statements but rather questions, requests, commands, etc. and from incomplete expressions, that is, mere word strings (orationes imperfectae), such as homo albus. These kinds of expressions, according to Abelard, do not differ in the understanding they present but in the way they present it. (shrink)
