The article addresses two closely related questions: What are the criteria of adequacy of logical formalization of natural language arguments, and what gives logic the authority to decide which arguments are good and which are bad? Our point of departure is the criticism of the conception of logical formalization put forth, in a recent paper, by M. Baumgartner and T. Lampert. We argue that their account of formalization as a kind of semantic analysis brings about more problems than it solves. (...) We also argue that the criteria of adequate formalization need not be based on truth conditions associated with logical formulas; in our view, they are better based on structural (inferential) grounds. We then put forward our own version of the criteria. The upshot of the discussion that follows is that the quest for an adequate formalization in a suitable logical language is best conceived of as the search for a Goodmanian reflective equilibrium.

In this study two strands of inferentialism are brought together: the philosophical doctrine of Brandom, according to which meanings are generally inferential roles, and the logical doctrine prioritizing proof-theory over model theory and approaching meaning in logical, especially proof-theoretical terms.

The paper presents an argument against a "metaphysical'* conception of logic according to which logic spells out a specific kind of mathematical structure that is somehow inherently related to our factual reasoning. In contrast, it is argued that it is always an empirical question as to whether a given mathematical structure really does captures a principle of reasoning. lMore generally, it is argued that it is not meaningful to replace an empirical investigation of a thing by an investigation of its (...) a priori analyzable structure without paying due attention to the question of whether it really is the structure of the thing in question.) It is proposed to elucidate the situation by distinguishing two essentially different realms with which our reason must deal: "the realm of the natural'*, constituted by the things of our empirical world, and "the realm of the formal'*, constituted by the structures that we use as "prisms'* to view, to make sense of, and to reconstruct the world. It is suggested that this vantage point may throw light on many foundational problems of logic. (shrink)

We know that lots of things are correct. (Helping people in need is correct. Moving the bishop diagonally when playing chess is correct. Adding 7 to 5 to make 12 is correct.) But where does this correctness come from? I argue that correctness is best seen as something we humans created in the process of forming our societies. This, admittedly, is speculative; but aside of this, there are facts that are more than speculations. In particular, I argue that our correctness (...) is based on normative attitudes, though these often determine only the criteria of correctness, letting the criteria to then determine what is correct independently of our will. Thus it holds both that correctness is wholly our creation and that it is independent of us in the sense that things may be correct even if we do not know that they are (or, indeed, think them incorrect).

Biological species are spatio-temporally localized entities. This fact led to the concept of species as individuals [11], [14], and, at the same time, to the refutation of essentialism in evolutionary biology and taxonomy. On the other hand, molecular biology is compatible with essentialisms of chemistry and physics. The new concept of "historical essences", which is presented in this paper, tries to reconcile antiessentialism of evolutionary biology with essentialism of molecular biology. Historical essences are those parts of genetic information which determine (...) characters relevant for the identification of a taxon. Since membership in a particular taxon is defined by the sharing of the most recent common ancestor, historical essences correspond to the genetic information responsible for the creation of such common ancestor. Historical essences, which are spatiotemporally localized, generate a particular arrangement of spatiotemporally unrestricted processes which lead to the creation, maintenance and reproduction of organisms. These arrangements are results of fortuitous confluence of biological and extrabiological circumstances . In historical essences such a sequence of historical contingencies is "conserved", which allows molecular taxonomy to reconstruct the phylogenetic relationships. The concept of historical essences can be seen as a post-Darwinian modification of the original Aristotleś term of essence - "to-ti-en-einai". (shrink)

Brandom’s inferentialism explains meaning in terms of inferential rules. As he insists that “the normative” is not reducible to “the natural,” inferentialism would seem an unlikely ally of naturalism. However, in this paper I suggest that Brandom’s theory of language harbors insights which can promote a naturalistic theory of meaning and language, and that a naturalistic version of Brandom’s inferentialism might have great potential. Also I sketch the lines along which such a theory could be built.

We investigate several ideal versions of the pseudointersection number \(\mathfrak {p}\), ideal slalom numbers, and associated topological spaces with the focus on selection principles. However, it turns out that well-known pseudointersection invariant \(\mathtt {cov}^*({\mathcal I})\) has a crucial influence on the studied notions. For an invariant \(\mathfrak {p}_\mathrm {K}({\mathcal J})\) introduced by Borodulin-Nadzieja and Farkas (Arch. Math. Logic 51:187–202, 2012), and an invariant \(\mathfrak {p}_\mathrm {K}({\mathcal I},{\mathcal J})\) introduced by Repický (Real Anal. Exchange 46:367–394, 2021), we have $$\begin{aligned} \min \{\mathfrak (...) {p}_\mathrm {K}({\mathcal I}),\mathtt {cov}^*({\mathcal I})\}=\mathfrak {p},\qquad \min \{\mathfrak {p}_\mathrm {K}({\mathcal I},{\mathcal J}),\mathtt {cov}^*({\mathcal J})\}\le \mathtt {cov}^*({\mathcal I}), \end{aligned}$$ respectively. In addition to the first inequality, for a slalom invariant \(\mathfrak {sl_e}({\mathcal I},{\mathcal J})\) introduced in Šupina (J. Math. Anal. Appl. 434:477–491, 2016), we show that $$\begin{aligned} \min \{\mathfrak {p}_\mathrm {K}({\mathcal I}),\mathfrak {sl_e}({\mathcal I},{\mathcal J}),\mathtt {cov}^*({\mathcal J})\}=\mathfrak {p}. \end{aligned}$$ Finally, we obtain a consistency that ideal versions of the Fréchet–Urysohn property and the strictly Fréchet–Urysohn property are distinguished.

While according to the inferentialists, meaning is always a kind of inferential role, proponents of other approaches to semantics often doubt that actual meanings, as they see them, can be generally reduced to inferential roles. In this paper we propose a formal framework for considering the hypothesis of the.

Growth modelling is of interest to scientists in various disciplines. In our article, we will collect 17 models designed for growth modelling, appraise these models and contribute to the discussion of their applicability. The merit of the paper lies in studying the convergence properties of nonlinear regression in selected models. Our studies will be performed mainly concerning the quality of the obtained estimates, which are closely related to the intrinsic curvature of the model according to Bates and Watts. This curvature (...) determines the size of the linearization domains. Only if the initial solution is in this domain, then the convergence of the estimate in nonlinear regression is guaranteed. The primary goal is to design a methodology for selecting a growth model. We will demonstrate fruitfulness of our methodology on the weight measurements of 10 calves under 25 months of age from cowsheds in the village Záluží in the Czech Republic. Estimated parameters of growth curves, sizes of linearization domain, calculated residues and coefficients of determination indices will be the subject of discussion. (shrink)

Normativity is one of the keywords of contemporary philosophical discussions. It is clear that philosophy has to do not only with theories, but also with norms (especially in ethics); but more and more current philosophers are busy arguing that, in addition, those parts of philosophy where norms are prima facie not in high focus, such as philosophy of language or philosophy of mind, have kinds of "normative dimensions". However, not everybody subscribes to this enthusiasm for normativity. Within philosophy, there is, (...) for example, an ongoing fierce discussion between 'normativists' and 'anti-normativists' about the normativity of meaning1 . A similar, thought I think both much broader and much deeper discussion concerning normativity has been launched within the context of philosophical and scientific accounts for human societies. Should we, explaining how a society works, merely state the facts concerning the behavior of the members of the society in the way natural scientists describe the behavior of ants in an anthill, or how they describe the 'behavior' of particles in an atom, or do we, over and above this, need to take a recourse to some 'normative facts'? This dispute, of course, partly reincarnates of traditional debate about the differences between Geisteswissenschaften and Naturwissenschaften as we know it from Dilthey, Schleimermacher or Max Weber; in this very specific form it, however, acquires a rather 2 transparent shape, in which it seems it might be resolvable by critical scrutiny . The current dispute is fuelled by the anti-normativists' rejection of normativism as the general claim that to account for human societies (and their products, such as meanings), we need to account for something over and above ordinary, causal, scientific facts; whereas the 'normativists' argue that to have a truly explanatory account of human societies, human languages or human practices we cannot make do stating what there is – that in some sense we need to say something about what ought to be..

Dieser Beitrag nimmt drei Perspektiven ein. Zunächst geht es um Ikonografien der Fliege und des Totenkopfes innerhalb der Stilllebenmalerei seit der Frühen Neuzeit und um die doppelte Vergänglichkeitsmetaphorik, die aus der Kombination von Motiv und Genre resultiert. Zudem geht die Untersuchung der Frage nach, welche medialen und semantischen Verschiebungen bei dem Übertrag dieser dichten Vanitas-Konfiguration in die Fotografie entstehen. Mein Fokus liegt dabei auf den zeitgenössischen Arbeiten der amerikanischen Fotografin Paulette Tavormina und ihren zwischen 2013 und 2015 entstandenen Re-Inszenierungen historischer (...) Stillleben-Darstellungen. Aus der motiv- und gattungsspezifischen sowie der medialen Perspektive ergeben sich schließlich Fragestellungen, die das Thema Vanitas in seiner moralisierenden wie auch zeitlichen Dimension thematisieren. So stelle ich zwei konträre Formen der Temporalität in den Stillleben mit Fliege und Totenkopf zur Diskussion: das Enden und das Sich-Verflüchtigen. (shrink)

The volume presents the views of ten authors from four PostCommunist Central and East European countries (Czech Republic, Slovakia, Poland and Latvia) on the impact of emerging technologies on human condition. They analyse the topic from anthropological, ethical, philosophical, ontological, empirical and legal perspectives.

Kniha, která vznikla na základě bohatých vědeckých a pedagogických zkušeností autora, přednášejícího na filosofické fakultě UK v Praze, je v současně době jedinou prací přehledového typu z oboru dějin estetických teorií a názorů vnaší literatuře. Obsahuje dějiny estetiky evropského okruhu od antiky až po začátek 20. století, v nichž Volek hledá smysl nauky o krásnu a sleduje přínosy jednotlivých osobností na pozadí dobového života společnosti.

Logic is usually presented as a tool of rational inquiry; however, many logicians in fact treat logic so that it does not serve us, but rather governs us – as rational beings we are subordinated to the logical laws we aspire to disclose. We denote the view that logic primarily serves us as logica serviens, while denoting the thesis that it primarily governs our reasoning as logica dominans. We argue that treating logic as logica dominans is misguided, for it leads (...) to the idea of a “genuine” logic within a “genuine” language. Instead of this, we offer a naturalistic picture, according to which the only languages that exist are the natural languages and the artificial languages logicians have built. There is, we argue, no language beyond these, especially none that would be a wholesome vehicle of reasoning like the natural languages and yet be transparently rigorous like the artificial ones. Logic is a matter of using the artificial languages as idealized models of the natural ones, whereby we pinpoint the laws of logic by means of zooming in on a reflective equilibrium. (shrink)

In this paper we put forward and defend a view of the nature of logic that we call moderate anti-exceptionalism. In the first part of the paper we focus on the problem of genuine logical validity and consequence. We make use of examples from current debates to show that attempts to pinpoint the one and only authentic logic inevitably either yield irrefutable theories or lead to dead ends. We then outline a thoroughly naturalist account of logical consequence as grounded in (...) rules implicit in human linguistic practices. We insist that there are only two existing kinds of language: natural languages, and artificial languages that have been forged by us. There is thus no room for a "genuine" language and hence for "genuine" logic. We conclude that though logical theories are established—and are liable to criticism—in a similar fashion as those of the sciences, and in this sense logic is not exceptional, to fulfill its mission logic must lay a claim to normative authority over our argumentation and reasoning, which makes its methodology somewhat special. Logical theory is not meant to provide just an explanation, the standards it establishes serve also as a tool, providing for a reinforcement of our rational communication. (shrink)

The followers of Wilfrid Sellars are often divided into “right” and “left” Sellarsians, according to whether they believe, in Mark Lance's words, that “linguistic roles constitutive of meaning and captured by dot quoted words are ‘normative all the way down.’” The present article anatomizes this division and argues that it is not easy to give it a nontrivial sense. In particular, the article argues that it is not really possible to construe it as a controversy related to ontology, and goes (...) on to argue that it is also not easy to construe it as one concerning the translatability of the normative idiom into the non-normative one. The conclusion is that the only coherent interpretation of this disagreement is as a disagreement about the possibility and desirability of assuming a standpoint “inside” our linguistic practices.

This book offers a comprehensive account of logic that addresses fundamental issues concerning the nature and foundations of the discipline. The authors claim that these foundations can not only be established without the need for strong metaphysical assumptions, but also without hypostasizing logical forms as specific entities. They present a systematic argument that the primary subject matter of logic is our linguistic interaction rather than our private reasoning and it is thus misleading to see logic as revealing "the laws of (...) thought". In this sense, fundamental logical laws are implicit to our "language games" and are thus more similar to social norms than to the laws of nature. Peregrin and Svoboda also show that logical theories, despite the fact that they rely on rules implicit to our actual linguistic practice, firm up these rules and make them explicit. By carefully scrutinizing the project of logical analysis, the authors demonstrate that logical rules can be best seen as products of the so called reflective equilibrium. They suggest that we can profit from viewing languages as "inferential landscapes" and logicians as "geographers" who map them and try to pave safe routes through them. This book is an essential resource for scholars and researchers engaged with the foundations of logical theories and the philosophy of language. (shrink)

Following an historical survey of ethical perspectives, the author focuses on an emerging "market ethics" dictating economic, cultural and legal principles and practices. He is especially concerned with the subsequent loss of human and social capital, and suggests the need for reviving those vital ethical considerations, especially during this time of transition for The Czech Republic and other Eastern European nations.

The great revolutions of modern times have been analysed from various angles, but their civilizational aspects and contexts have on the whole been neglected. More specifically, the major 20th-century revolutions can be seen as particularly important cases of intercivilizational encounters. They represent different responses to the ascendant and challenging civilization of the West. The Western civilizational trajectory (or set of trajectories), based on a shift from fideism to empiricism and on multiple social dynamics fuelled by this cultural reorientation (such as (...) those of the capittalist economy and the one-nation-state), is selectively appropriated by non-Western societies which at the same time reject the less adaptable parts of the West in the name of traditional or invented alternatives. Russia, China, Turkey and Iran are analysed as variations of this recurrent pattern. At one end of the spectrum, the Russian revolution aspired to transcend Western models on the basis of a more radical interpretation of their own principles; at the other, the Iranian revolution, made up of several episodes with intervals in between, has been characterized by an exceptionally tenacious - and in some ways inventive - defence of a pre-existing civilizational identity.

Is logic, feasibly, a product of natural selection? In this paper we treat this question as dependent upon the prior question of where logic is founded. After excluding other possibilities, we conclude that logic resides in our language, in the shape of inferential rules governing the logical vocabulary of the language. This means that knowledge of (the laws of) logic is inseparable from the possession of the logical constants they govern. In this sense, logic may be seen as a product (...) of natural selection: the emergence of logic requires the development of creatures who can wield structured languages of a specific complexity, and who are capable of putting the languages to use within specific discursive practices.

Recent decades are marked by the upswing of the use of the term “normativity“ not only in philosophical discussions, but increasingly also within reports of empirical scientists. This may invoke the question how far these developments overlap and in how far they go past each other. A significant overlap might lead to an interesting coalescence of the two approaches to norms, which may provide for a ”naturalization” of some philosophical speculations about normativity, putting them on a firmer foundation, while offering (...) the empirical scientists some new impulses for directing their research. In this paper I give an overview of some recent empirical results concerning human normativity and I point out a certain philosophical tradition, rooted especially in the works of Wittgenstein, Sellars and Brandom, which treats normativity so that it becomes more or less compatible with these results.

Článok je pokusom o interpretáciu Platónovho dialógu Faidón vo svetle prvých Sókratových slov, ktoré v ňom zaznievajú. Sókratova krátka úvaha o vzťahu príjemného a nepríjemného je vzápätí vsadená do kontextu konfrontácie filozofického a básnického typu explanácie. Zaujímavé je, že Sókratov komentár k snu, ktorý ho kedysi vyzval k praktizovaniu múzického umenia, neprezentuje oba prístupy ako navzájom sa vylučujúce, ale skôr ako komplementárne. V tejto perspektíve je možné čítať Faidóna ako náčrt „vysokej“ filozofie oddelených ideí, a zároveň ako výzvu o jej (...) doplnenie „nižšou“ filozofiou zmesí. (shrink)

Cieľom článku je nanovo reflektovať činnosť jednej z najslávnejších ženských filozofiek, Hip­parchie z Maróneie. Naším zámerom je ukázať, prečo sa stala v porovnaní s inými ženami antiky taká významná a v mnohom signifikantná pre ďalší vývoj procesu ženskej eman­cipácie. Hlavným svedectvom je pre nás fragment SSR V I 1 od Diogena Laertského, ktorý kladieme do súvislosti s ďalšími antickými správami o Antisthenovi a raných kynikoch. Dve hlavné témy Diogenovho svedectva sú Kratétova svadba s Hipparchiou a spor Hipparchie s Theodórom. Vo (...) výklade poukazujeme na momenty, v ktorých je filozofická osobnosť Hip­parchie nadčasová a inšpiratívna aj pre súčasnosť. (shrink)

There has been much controversy over the completeness and unity of Euripides᾽Heraclidaein the last two centuries. Hermann᾽s characterization of the play as a heavily mutilated piece, which was adopted by Kirchhoff, Wilamowitz, Nauck and Murray, prevailed for a long time. Wilamowitz's thesis that theHeraclidaewas revised by the ancient director found its adherents. It was Günther Zuntz who led the general offensive against this widely accepted opinion and whose critical scrutiny reversed the view of the play. According to Zuntz, the play (...) has come down to us substantially as it was written. The alleged mutilation, as well as the specific dramatic technique, shortness and swiftness of theHeraclidae, also influenced the general evaluation of the play as a minor or odd piece. It was Günter Zuntz again and also Franz Stoessl who reconstituted the reputation of theHeraclidae. Today Euripides᾽Heraclidaeis studied and recognized as a classicalHikesiedrama, a play deeply rooted in Athenian ideology and in the social and religious context of fifth-century Athens, and representing various aspects of communal life. Since the play has been interpreted and scrutinized from a very wide range of perspectives, I do not aim at a radically new general interpretation of theHeraclidae, but I would like to make a short remark on an aspect of it which has, as far as I know, been neglected or only briefly referred to: the term ἀμηχανία in crucial passages of the play, which signifies, or rather describes, a situation which is desperate, hopeless, and with no way out. I would like to show that for the characters in theHeraclidaewho follow the ideal of justice, in contrast to those who prefer profit, no situation is hopeless, even as it was not for Heracles, who managed to do things which could be evaluated as impossible. On the other hand, those who opt for the Heraclean ideal have to prepare to face the ultimate challenges. (shrink)

A set A of vertices of a graph G is called d-scattered in G if no two d-neighborhoods of (distinct) vertices of A intersect. In other words, A is d-scattered if no two distinct vertices of A have distance at most 2d. This notion was isolated in the context of finite model theory by Ajtai and Gurevich and recently it played a prominent role in the study of homomorphism preservation theorems for special classes of structures (such as minor closed classes). (...) This in turn led to the notions of wide, almost wide and quasi-wide classes of graphs. It has been proved previously that minor closed classes and classes of graphs with locally forbidden minors are examples of such classes and thus (relativized) homomorphism preservation theorem holds for them. In this paper we show that (more general) classes with bounded expansion and (newly defined) classes with bounded local expansion and even (very general) nowhere dense classes are quasi wide. This not only strictly generalizes the previous results but it also provides new proofs and algorithms for some of the old results. It appears that bounded expansion and nowhere dense classes are perhaps a proper setting for investigation of wide-type classes as in several instances we obtain a structural characterization. This also puts classes of bounded expansion in the new context. Our motivation stems from finite dualities. As a corollary we obtain that any homomorphism closed first order definable property restricted to a bounded expansion class is a restricted duality. (shrink)

Davidson’s anomalous monism is based on the assumption that a human being can be described or accounted for in two very different ways, using two very different and indeed incommensurable conceptual frameworks, namely the physicalistic vocabulary of science and the mentalistic vocabulary employed by the ‘theories’ we make about each other when we interact and communicate. Also Sellars maintains that we have two alternative pictures of the world and especially of us humans as its parts, namely the scientific image and (...) the manifest image. At first sight, the views of the two philosophers may seem quite similar; however, the true extent of this apparent similarity is worth exploring. To that end, in this paper we tackle the following questions: Are Sellars’ reasons for claiming the irreducibility of his manifest image to the scientific image the same or similar to those that Davidson has for asserting the irreducibility of his mentalistic idiom to the scientific one? Is the normativity informing Sellars’ manifest image of the same kind as that informing Davidson’s mentalistic idiom? Do the notions of rationality considered by Sellars and Davidson coincide?
