Bernard Bolzano (1781 - 1848) war ein vielseitiger Philosoph. Seine Interessen bedecken alle Bereiche der Logik über Physik bis zur den Wissenschaften des Übersinnlichen. Die moderne Bolzano-Rezeption schätzt an seinem Werk vor allem die mathematischen, logischen und erkenntnistheoretischen Bemühungen. Trotz des großen Stellenwertes, den Mathematik und Logik in der Forschung Bolzanos einnehmen, können sie die beachtliche Dichte der Querverbindungen seines Denkens nicht ausschöpfen. In diesem Band wird eine kritische Rekonstruktion der theologisch-metaphysischen Untersuchungen (anhand seiner Athanasia) Bolzanos geliefert, welche (...) die Wechselwirkungen aufzeigen soll, die zwischen den theologisch-metaphysischen und den logisch-mathematischen Untersuchungen besteht.

El artículo tiene por objetivo analizar ciertos pasajes fundamentales de la Wissenschaftslehre y de las Paradoxien des Unendlichen de Bernard Bolzano en cuanto al análisis conjuntista se refiere. En dichos pasajes, Bolzano desarrolla conceptos fundamentales tales como multitud, colección e infinito que anticipan el carácter conjuntista y del análisis matemático moderno. Asimismo, se presentará un breve estudio de las Contribuciones a una más fundada exposición de la matemática y el apéndice, Sobre la teoría kantiana de la construcción de (...) conceptos a través de intuiciones, textos donde Bolzano muestra su rechazo por Kant.The article addresses the treatment of certain fundamental passages from Bolzano’s Wissenschaftslehre and Paradoxien des Unendlichen. In these passages, Bolzano describes some of his key concepts such “Multitude”, “Collections” and “Infinite” in the context of mathematical analysis and Set theory. Therefore, I discuss at length the unknown Contributions to a Better-Grounded Presentation of Mathematics and the appendix On the Kantian Theory of the Construction of Concepts through Intuitions, texts where Bolzano shows his rejection of Kant.

Bolzano incorporated Kant's distinction between intuitions and concepts into the doctrine of propositions by distinguishing between conceptual (Begriffssätze an sich) and intuitive propositions (Anschauungssätze an sich). An intuitive proposition contains at least one objective intuition, that is, a simple idea that represents exactly one object; a conceptual proposition contains no objective intuition. After Bolzano, philosophers dispensed with the distinction between conceptual and intuitive propositions. So why did Bolzano attach philosophical importance to it? I will argue that, ultimately, (...) the value of the distinction lies in the fact that conceptual and intuitive truths have different objective grounds: if a conceptual truth is grounded at all, its ground is a conceptual truth. The difference in grounds between conceptual and intuitive truths motivates Bolzano's criticism of Kant's view that intuition plays the fundamental role in mathematics, a conceptual science by Bolzano's lights.

La filosofia austriaca presenta tratti di originalità nei suoi esponenti: anzitutto B. Bolzano, F. Brentano e la sua scuola. Grazie all’influenza di Herbart essa rimane estranea all’idealismo e al neokantismo e sviluppa temi poi decisivi nel novecento come la fenomenologia e la filosofia analitica.

The roots of the Lvov-Warsaw School can be traced back to Aristotle himself. But in later times we better put them into thinking GW Leibniz and who somehow inherited many of these ways of thinking, such as the philosopher and mathematician Bernhard Bolzano. Since he would pass the key figure of Franz Brentano, who had as one of his disciples to Kazimierz Twardowski, which starts with the brilliant Polish school of mathematics and philosophy dealt with. Among them, one (...) of the most interesting thinkers must be Jan Lukasiewicz, the father of many-valued logic.Jan Łukasiewicz began teaching at the University of Lvov, and then at Warsaw, but after World War II must to continue in Dublin. Some questions may be very astonishing in the CV of Łukasiewicz. For instance, that a firstly Polish Minister of Education in Paderewski cabinet, into the new Polish Republic, and also Rector for two times at Warsaw University, was awarded with a Doctorate ‘Honoris Causa’ in spring 1936, at University of Münster, into the maximum of effervescency of Nazism in Germany. The explanation must be their good relation with a very good friend, the former theologian, and then logician, Heinrich Schölz, who was the first Chairman of Mathematical Logic in German universities.Łukasiewicz firstly studied Law, and then Mathematics and Philosophy in Lvov. His doctoral supervisor was Kazimierz Twardowski, and in 1902 he obtain his Ph. D. title with a very special mention: ‘sub auspiciis Imperatoris’. Also he received a doctorate ring with diamonds from the Kaiser of the Austro-Hungarian Empire, Franz Joseph I.From 1902, Łukasiewicz was employed as a private teacher, and also as a desk in the Universitary Library of Lvov. So it was until 1904 when he obtained a scholarship to study abroad. He defends his ‘Habilitationschrift’ in 1906, entitled “Analysis and construction of the concept of cause”. This permits to give university courses. His first lectures were on the Algebra of Logic, according to the recent translation to Polish of this book of the French logician Louis Couturat.Between 1902 and 1906, Lukasiewicz continued his studies in the universities of Berlin and Leuwen. In 1906, by his ‘Habilitationschrift’, he obtain the qualification as university professor at Lvov. And the, in 1911, he was appointed as associate professor in his ‘alma mater’.Jan Łukasiewicz was also very active in historical research on logic, giving a new and up-to-date interpretation of Aristotle’s syllogism and of the Stoics’ propositional calculus. According to Scholz, the better pages on history of logic are due to him. And also, as Arianna Betti says, “Jan Lukasiewicz is first and foremost associated with the rejection of the Principle of Bivalence and the discovery of Many-Valued Logic.”The discovery of MVL by Lukasiewicz was in 1918, a little earlier than Emil Leon Post. According to Jan Wolenski, “although Post’s remarks were parenthetical and extremely condensed, Lukasiewicz explained his intuitions and motivations carefully and at length. He was guided by considerations about future contingents and the concept of possibility”. So, he introduces, firstly, three-valued logic, then four-valued logic, generalized to logics with an arbitrary finite number of veritative values, and finally, to logics with a countably infinite-valued number of such values.Very noteworthy is his treatment of the history of logic in the light of the new formal logic. Thus, not only he addressed the issue of future contingents departing from Aristotle, but also put in value logic of the Stoics, at least so far taken. In fact, Heinrich Scholz said, rightly, that Lukasiewicz had written the most lucid pages on the history of logic. (shrink)

I contrast two approaches to the interpretation of generics such as ‘ravens are black:’ majority-based views, on which they are about what is the case most of the time, and inquiry-based views, on which they are about a feature we focus on in inquiry. I argue that majority-based views face far more systematic counterexamples than has previously been supposed. They cannot account for generics about kinds with multiple characteristic properties, such as ‘elephants live in Africa and Asia.’ I then go (...) on to sketch an inquiry-based view. (shrink)

Theories of explanation seek to tell us what distinctively explanatory information is. The most ambitious ones, such as the DN-account, seek to tell us what an explanation is, tout court. Less ambitious ones, such as causal theories, restrict themselves to a particular domain of inquiry. The least ambitious theories constitute outright skepticism, holding that there is no reasonably unified phenomenon to give an account of. On these views, it is impossible to give any theories of explanation at all. I argue (...) that both the less ambitious and outright skeptical varieties are committed to a certain context-sensitivity of our explanatory discourse. And though this discourse is almost certainly context-sensitive in some respects, it does not exhibit the context-sensitivity less than fully ambitious theories are committed to. Therefore, all accounts that seek to restrict themselves in scope, including causal accounts of explanation, fail. (shrink)

Večina slikovnih koncepcij boleha za tem, da začenjajo previsoko, namreč na ravni slikovnih del in slikovnih medijev. Zaradi tega pri doživljanju slike nismo pozorni na razpoke in brezna. Ta očitek zadeva tako filozofske teorije slike kot tudi umetnostno teorijo, umetnostno zgodovino in muzejsko prakso, ki se ne zna več čuditi temu, da obstaja nekaj takega kot slike. Naslednji razmisleki se vrtijo okoli geneze slike, ki omogoča vdor v zaprtost nekega v lepi ali nič več lepi videz ujetega estetskega sveta, tako (...) da se sprostijo tako pred- kot tudi post-estetski motivi umetnosti. Umetnost terja genealogijo, ki bo enakovredna Nietzschejevi genealogiji morale ali Husserlovi genealogiji logike.The majority of pictorial conceptions are troubled by starting from too high a level, namely from the level of fine-art works and fine-art media. This is why we are likely to fail to notice crevices and chasms. This reproach is directed both at philosophical theories of the painting and at art theory, art history and museum practice, which is no longer able to express wonder at the sheer existence of the painting. The following reflections tackle the issue of the genesis of the painting, which enables us to penetrate into the closed sphere of the aesthetic world as caught in the beautiful, or no longer beautiful, appearance, and thereby sets free pre- as well as post-aesthetical motives of art. Art demands a genealogy on an equal stand with Nietzsche’s genealogy of morality or Husserl’s genealogy of logic. (shrink)

Without directly addressing the Demarcation Problem for logic—the problem of distinguishing logical vocabulary from others—we focus on distinctive aspects of logical vocabulary in pursuit of a second goal in the philosophy of logic, namely, proposing criteria for the justification of logical rules. Our preferred approach has three components. Two of these are effectively Belnap’s, but with a twist. We agree with Belnap’s response to Prior’s challenge to inferentialist characterisations of the meanings of logical constants. Belnap argued that for a logical (...) constant to exist, its rules must be conservative over a previously given consequence relation and guarantee the uniqueness of the constant. The twist is that we require logical vocabulary to be provably conservative, not over a previously given formal consequence relation, but over a previously given meaningful vocabulary of a language. Uniqueness is also a feature defined in terms of provability: if two syntactically distinguished expressions are governed by the same rules, then formulas with them as main operators are interderivable. Belnap’s criteria are not only those for the existence of a logical constant, but more: they are what distinguishes logical vocabulary from all other expressions. It is the defining mark of a logical constant that it is provably conservative over the fragment of the language which excludes it and that its rules guarantee its uniqueness. The third component is the topic neutrality of logic. The provable conservativeness of logic over a previously given vocabulary of a language is motivated, in part, by appeal to molecularism in the theory of meaning. Molecularity is a feature endorsed by the theory of meaning as a whole, so it does not distinguish logical constants from other expressions. The same is true for conservativeness. We argue that molecularity, and hence conservativeness, are implicit presuppositions of speakers’ use of language: the addition of new vocabulary to a language is presupposed to be conservative. But this presupposition is one that we should be able reflectively to endorse (such as when attempting a rational reconstruction of the use of the vocabulary). Thus, where conservativeness is found to fail, this defect should be remedied and the use of the vocabulary corrected (as in classical negation) or excised altogether (as in pejoratives). We go on to characterise a notion of topic neutrality, which we argue applies to logical vocabulary. We then note that reflective endorsement of the conservativeness of a topic neutral vocabulary requires a proof that the vocabulary is conservative relative to any base vocabulary. Thus we require that logical vocabulary be demonstrably conservative. Allying this requirement, distinctive of logic, to a general consideration about the commitments of assertion yields a mode of justification for logical constants akin to some conceptions of Harmony, i.e., to the idea that the consequences of assertion of a logical complex need to be warranted by the grounds and ought to be the strongest consequences warranted by the grounds. Intuitionistic logic acquires a somewhat familiar justification but emanating from a new motivation. (shrink)

This book collects essays from the 2006 and 2007 International Philosophy Colloquia Evian, centred around a central problem in the philosophy of mind: the relationship between the human faculty of sensory experience and the faculty of conceptual reflection, that is self-consciousness. Containing articles by philosophers of eight nationalities, in three languages (English, French, German), and of "analytical" as well as "continental" provenance, it beautifully represents the spirit of the colloquia. Authors include Joshua Andresen (AU Beirut), Valérie Aucouturier (Kent U / (...) U Paris I), Karin de Boer (KU Leuven), Santiago Echeverri (U Genève), Roberto Farneti (LU Bolzano), Tim Henning (JLU Giessen), Felix Koch (Columbia U), Christophe Laudou (Madrid), David Lauer (FU Berlin), Jason Leddington (Bucknell U), Nicolas Monseu (UC Louvain), Soraya Nour (HU Berlin), Hans Bernhard Schmid (U Wien), Henning Tegtmeyer (U Leipzig).

Die in diesem Band enthaltenen Beiträge gehören in den Umkreis von Waldenfels' 1987 erschienenem Buch Ordnung im Zwielicht. Der dort vorgelegte Grundriß wird hier auf mannigfache Weise ausgeführt und fortgeführt - ein Materialienband also zu Ordnung im Zwielicht, doch gleichzeitig ein Vorbereitungsband zur Behandlung dessen, was Waldenfels dort responsive Rationalität genannt hat.

This paper investigates the interaction between semantic theories for cp-laws (roughly, laws that hold “all things equal”) and metaphysical theories of kinds in the special sciences. Its central conclusion is that cp-laws concerning kinds behave differently from cp-laws concerning non-kinds: “ravens are black” which concerns the kind corvus corax, behaves differently from from “albino ravens are white” which concerns the non-kind grouping of albino ravens. I argue that this difference is in the first instance logical: the two sorts of cp-laws (...) give rise to different inferential patterns. I draw two further conclusions. The difference in logical behavior poses a severe problem for extant semantic theories of cp-laws, and: we cannot elucidate the distinction between kinds and non-kinds by suggesting that only kinds can appear in laws.

Twenty Years After Communism is concerned with the explosion of a politics of memory triggered by the fall of state socialism in Eastern Europe, and it takes a comparative look at the ways that communism and its demise have been commemorated by major political actors across the region.

Various studies have shown that philosophizing with children at school can have a positive effect on cognitive, language and social skills. However, previous studies have not considered how the quality of the dialogue influences these outcomes. Addressing this gap, our article introduces a high-inference rating instrument to assess the quality of philosophical dialogue. This instrument features four quality dimensions: Philosophical Richness, Co-construction, Focus, and Restrained Facilitation. It was applied to evaluate 63 class dialogues from a Swiss study involving secondary-school students. (...) The article presents the instrument using excerpts from the study, along with initial validation information, showing its reliability in measuring philosophical dialogue quality. The significance of this research lies in its focus on the quality of philosophical dialogue, an aspect often overlooked in educational settings. By providing a tool to assess this quality, we open up new pathways for analyzing the effectiveness of philosophical dialogues in schools. This is especially relevant as educational systems increasingly recognize the importance of developing students' critical thinking and discussion skills. The findings highlight the potential of high-quality philosophical dialogues to enrich students' educational experiences and offer insights for educators and researchers into enhancing these interactions. This study contributes to a deeper understanding of how philosophical dialogue can be used as a powerful educational tool, not just for engaging students but for fostering meaningful and impactful learning.

Living corporeity is the intermediate element between nature and culture, which must be thought of as a reciprocal interconnection, since as corporeal beings we always move on a threshold. In the reflection of the bodily self, a doubling between the living body as a functioning subject and as a material object is revealed; after all, even one's own body sometimes takes on the features of a foreign body, as is the case in the experience of illness. In the technical instrument, (...) the body is prolonged and this highlights the connection between the technique of the thing and the technique of the self; however, despite the gradual autonomisation of the technical element from the living corporeity, there remains what escapes calculation and looms large in the subtraction of the alien.

Generics exhibit genericity, and though a theory of generics is closely connected to a theory of genericity, the two are distinct. They raise a host of interesting linguistic and philosophical issues, both separately and in their interaction. This chapter begins with a fairly manifest phenomenon one can observe in natural language. There is a range of sentences that, speaking intuitively, one can use to talk about kinds. It argues that there's no simple statistical criterion that systematically captures the patterns of (...) the truth and falsity of generics. Generics seem to not just be substantially independent of statistical facts in the world and at the time with respect to which they are evaluated. The chapter points‐out a likely form of context dependence in generics, and argues that on a quantificational approach to generics, the restrictor of the generic quantifier must be determined at least in part by the predicate at issue.

Reading Cassirer’s philosophy of myth: early signs of Heidegger’s late philosophy? In 1928, Heidegger’s book review of the second volume of Cassirer’s Philosophy of Symbolic Forms (The Mythical Thought) was published in the Deutsche Literaturzeitung. Cassirer’s text date of 1925, hence it is possible that Heidegger had read it even before the publication of Being and Time. What makes both texts worthy of a closer examination is the fact that several central motifs and terms of Heidegger’s later philosophy are already (...) present in these two texts. Heidegger focuses particularly on Cassirer’s reflections on the representation of mana (Mana-Vorstellung) in mythical thinking. This representation involves not only the distinction between the familiar and the unfamiliar, the ‘uncanniness’ or ‘not-at-homeness’ that befalls mightily the Dasein, but also the distinction between the sacred and the profane and that of the four world regions (Weltgegenden) and its organization in form of a cross. Although not everything that Heidegger announces is interpretable as full awareness of the future impact of these traces, one would wonder if the density with which they appear would be mere accident. Thus, the article contributes to the debate on the issue of the emerging of Heidegger’s late thought and its origins which can be traced back to the stage of genesis, or rather, the final draft of Being and Time.

Although Dagur and Alsatian represent two typologically distant language families, they share several similarities: both languages are endangered, do not have a unified spelling system, and have few available digital corpora. Given these challenges, the main aim of this article is to compare the noise in corpora for these languages and its impact on part-of-speech (POS) annotation and tagging. We first discuss what strategies can be used to reduce the noise due to spelling inconsistencies observed during corpus collection, using Dagur (...) as an example. We then observe that the distributions of POS trigrams in the manually annotated Dagur and Alsatian corpora are similar to those of typologically related languages in UD v2.12, laying the foundations for experimenting with zero-shot transfer approaches for automatic POS tagging. We evaluate some simple noise reduction strategies for POS tagging using the example of the Alsatian dialects and relying on their proximity to standard German. The results obtained confirm the important role of linguistic proximity in automatic POS tagging and the effectiveness of the proposed data transformation method. However, they also invite further interpretation of the capacities of multilingual models. (shrink)
