This is a comprehensive study of the Derveni Papyrus. The papyrus, found in 1962 near Thessaloniki, is not only one of the oldest surviving Greek papyri but is also considered by scholars as a document of primary importance for a better understanding of the religious and philosophical developments in the fifth and fourth centuries BC. Gábor Betegh aims to reconstruct and systematically analyse the different strata of the text and their interrelation by exploring the archaeological context; the interpretation of (...) rituals in the first columns of the text; the Orphic poem commented on by the author of the papyrus; and the cosmological and theological doctrines which emerge from the Derveni author's exegesis of the poem. Betegh discusses the place of the text in the context of late Presocratic philosophy and offers an important preliminary edition of the text of the papyrus with critical apparatus and English translation.

In much environmentally concerned literature, there is a burgeoning concern for the status and sustainability of human hope. Within Christian circles, this attention has often taken the form of eschatological reflection. While there is important warrant for attention to eschatology in Christian examinations of hope, I claim that to move so quickly from hope to eschatology is to confuse a species of Christian hope for a definition of hope itself; as such, it is important for theological ethicists to examine hope (...) also from the experiential perspective of the human hoper. In particular, this is important today given the shortcomings of an eschatological focus in addressing anxieties arising due to the environmental crisis. Through examining hope as a fallible human activity, one can come to better understand hope's importance to human life, its profound ambiguity, and the potential threat that the environmental crisis poses to it.

Which ultraproducts preserve the validity of formulas of higher order logics? To answer this question, we will introduce natural topologies on ultraproducts. We will show, that ultraproducts preserving certain higher order formulas can be characterized in terms of these topologies. As an application of the above results, we provide a constructive, purely model theoretic characterization for classes definable by second order existential formulas.

The article analyzes strategic manoeuvring within the pragmadialectical framework with respect to the selection of starting points in the opening stage to frame the arguments. The Terri Schiavo case is presented, which can provide interesting insights concerning this issue. I would like to show that resolution of the difference of opinion requires the resolution of a subordinate difference of opinion concerning how to label her medical state, and why discussants were not able to resolve this subordinate difference of opinion. After, (...) the conflict that arises between critical reasonableness and rhetorical effectiveness is examined and how strategic manoeuvring aims to resolve this conflict. In the final part of the paper I argue that the problems raised can be dealt with within the framework of pragma-dialectics. (shrink)

We prove a generalization of Alex Heller's existence theorem for recursion categories; this generalization was suggested by work of Di Paola and Montagna on syntactic P-recursion categories arising from consistent extensions of Peano Arithmetic, and by the examples of recursion categories of coalgebras. Let B=BX be a uniformly generated isotypical B#-subcategory of an iteration category C, where X is an isotypical object of C. We give calculations for the existence of a weak Turing morphism in the Turing completion Tur of (...) B when C is separated; i.e., when connected domains in C are jointly epimorphic. Our proof generalizes as follows. Let D be a separated iteration category and let L : C → D be an iteration functor; i.e., a functor which preserves domains, coproducts, zero morphisms and the iteration operator; it is crucial for the generalization that an iteration functor need not preserve products. If L is faithful, then Tur is a recursion category. (shrink)

Let be a countable first order structure and endow the universe of with the discrete topology. Then the automorphism group of becomes a topological group. A tuple of automorphisms is defined to be weakly generic iff its diagonal conjugacy class (in the algebraic sense) is dense (in the topological sense) and the ‐orbit of each is finite. Existence of tuples of weakly generic automorphisms are interesting from the point of view of model theory as well as from the point of (...) view of finite combinatorics.The main results of the present work are as follows. In Theorem 2.6 we characterize the existence of tuples of weakly generic automorphisms with the aid of the profinite topology of free groups. In Corollary 2.12 we will show that if has finite topological rank r (and satisfies a further, mild technical condition) then the existence of a weakly generic tuple in implies the existence of weakly generic tuples in for all natural number. Finally, in Theorem 3.2 we show that if is a countable model of an ℵ0‐categorical, simple theory in which all types over the empty set are stationary and has a pair of weakly generic automorphisms then it has tuples of weakly generic automorphisms of arbitrary finite length.At the technical level we will combine elementary investigations about the profinite topology of free groups with the results of [11] about topological ranks of the automorphism groups of some structures.

Otto Neurath’s thoroughgoing anti-foundationalism is connected to the recognition that protocol sentences are not inviolable, that is they are fallible and their choice cannot be determined: ‘Poincaré, Duhem and others have adequately shown that even if we have agreed on the protocol statements, there is a not limited number of equally applicable, possible systems of hypotheses. We have extended this tenet of the uncertainty of systems of hypotheses to all statements, including protocol statements that are alterable in principle’. Later historiography (...) has called Neurath’s extension of Duhemian holism the Neurath principle. Based on a study of Neurath’s early works on the history of optics, the paper investigates a previously unnoticed influence on the development of this principle, Neurath’s reading of Goethe’s Theory of colours. The historical and polemical parts of Goethe’s tripartite book provided Neurath with ideal examples for the vertical extension of Duhem’s thesis to observation statements. Moreover, Goethe’s critique of the language of science and his views on the theory-ladenness of observation, as well as on the history of science show strong parallels to many of Neurath’s ideas. These demonstrate the existence of surprisingly direct textual links between Romantic views on science and the development of twentieth-century philosophy of science. Neurath’s usage of Goethe’s examples also indicates that the birth of the Neurath principle is more tightly connected to actual scientific practice than to theory-testing, and that by admitting the theory-ladenness of observation reports and fallibility of protocol statements Neurath does not throw empiricism overboard.Keywords: Otto Neurath; J. W. von Goethe; Holism; Theory-ladenness; Duhem-Quine thesis; Romantic science. (shrink)

Current philosophical reflections on science have departed from mainstream history of science with respect to both methodology and conclusions. The article investigates how different approaches to reconstructing commitments can explain these differences and facilitate a mutual understanding and communication of these two perspectives on science. Translating the differences into problems pertaining to principles of charity, the paper offers a platform for clarification and resolution of the differences between the two perspectives. The outlined contextual approach occupies a middle ground between mainstream (...) history and sociology of science, bracketing questions of rationality, and individual coherence-maximizing, rationality-centered approaches. It can satisfy those, who believe that science is an epistemically privileged endeavor, and its epistemic content should not be neglected when reconstructing the scientists’ positions. It can also satisfy those who hold that it is naive to believe that the immediate context, e.g. the challenges to a theory, the expectations of the author about his audience, etc., does not affect the position a scientist takes. Its theoretical considerations are exemplified with a close study of the debate following the 1672 publication of Newton's theory of light and colours, also offering a novel reading of the development of his methodological views concerning the demonstrativity of the famous crucial experiment. Although we only show the capacity of the framework to analyze a direct controversy, given that it is hard to think about any scientific text as detached from an argumentative context, this approach has the potential to be a general guide for interpretation.

Here we investigate the classes RCA $^\uparrow_\alpha$ of representable directed cylindric algebras of dimension α introduced by Nemeti[12]. RCA $^\uparrow_\alpha$ can be seen in two different ways: first, as an algebraic counterpart of higher order logics and second, as a cylindric algebraic analogue of Quasi-Projective Relation Algebras. We will give a new, "purely cylindric algebraic" proof for the following theorems of Nemeti: (i) RCA $^\uparrow_\alpha$ is a finitely axiomatizable variety whenever α ≥ 3 is finite and (ii) one can obtain (...) a strong representation theorem for RCA $^\uparrow_\alpha$ if one chooses an appropriate (non-well-founded) set theory as foundation of mathematics. These results provide a purely cylindric algebraic solution for the Finitization Problem (in the sense of [11]) in some non-well-founded set theories. (shrink)

Olaf Müller’s book develops a new case for underdetermination, and, as he is focusing on theories of a ‘limited domain’, this assumes the containability of the theories. First, the paper argues that Müller’s theory of darkness is fundamentally Newtonian, but for Newton’s optical theory the type of theoretical structure Müller adopts is problematic. Second, the paper discusses seventeenth-century challenges to Newton, changes in the proof-structure of Newton’s optical theory, and how these affect Müller’s reconstruction. Müller’s book provides empirically equivalent theories, (...) yet the historical theories were not empirically equivalent, and the same experiments were used to extract different bodies of evidence to rebut the opponent. Third, Goethe’s multi-layered critique of Newton’s experimental proof is investigated, including his developmental account of prismatic colours, the role of experimental series in rejecting Newton’s observations, and his incorporation of the ‘limited domain’ of prismatic colours in a broader framework. Two key elements of Goethe’s method, polarity and strengthening are discussed in contrast to Müller, who only utilises polarity in his account. Finally Neurath’s attempts to come to grips with the optical controversies and the prism-experiments with ‘blurred edges’ are recalled. Müller also discusses in detail some of these experiments and heavily draws on Quine. Neurath developed Duhem’s and Poincaré’s conventionalist insights and had good reasons to be pessimistic about theory-containment. Their differences provide some additions to the history of the Duhem–Quine thesis. (shrink)

In this short study, I attempt to reconstruct the main conceptual components of Edmund Husserl’s concept of death following the leading clue of his late transcendental phenomenological methodology. First, I summarise his thoughts on death, from the point of view of “the natural attitude”, as an event in the world. Then, I try and explore the manifold senses of the limit phenomenon of death as a multidimensional transcendental phenomenological problem in all of its intersubjective-world constitutive, personal-primordial, and metaphysical-constructive layers of (...) meanings, respectively. By doing so, I also hope that the path we travel can serve the reader as an opportunity for a personal and reflective confrontation with death. (shrink)

The essay focuses on controversies where the debated issues are complex, the exchange involves several participants, and extends over long periods. Examples include the Methodenstreit, the Hering-Helmholtz controversy or the debates over Newton’s or Darwin’s views. In these cases controversies lasted for several generations, and polarisation is a recurring trait of the exchanges. The reconstructions and evaluations of the partly polemical exchanges also exhibit heterogeneity and polarisation. Although I pick an early example of the Newtonian controversies, Darwin’s argument in The (...) Origin of Species can also be variously reconstructed. When scientific controversies that involve complex utterances are investigated, a specific problem arises, as in these situations the protagonist presenting a bundle of claims to a non-unified audience cannot fully control meaning-attribution of his utterances, and, given what we know about individual cognition, the more heterogeneous audience he succeeds in persuading, the less clear the meaning becomes. While the acceptance of a position increases potential for action, the growth in consent comes together with a fuzzy content. To problematise the role of polarisation, the significance of this description with respect to knowledge-production is investigated from both an individual and a social epistemological standpoint to answer the question: How is rhetoric epistemic in cases when at least two views on a given issue are seen as persuasively supported by communities? If engaging in a controversy is a means-to-an-end activity aimed at persuasion, directed at achieving attitude-change in recipients, how does the argumentative goal of an individual translate to epistémé in extended scientific controversies?

The notion of ultratopologies was introduced in [6] motivated by the model theory of first and higher order logics. In [6] we established some model theoretical applications of ultratopologies, for example, we provided a purely set theoretical characterization for classes de.nable by second order existential formulas. The present note deals with topological properties of ultratopologies, like density and compactness.

The uniform halting problem (UH) can be stated as follows.Give a decision procedure which for any given Turing machine (TM) will decide whether or not it has an immortal instantaneous description (ID).An ID is called immortal if it has no terminal successor. As it is generally the case in the literature (see e.g. Minsky [3, p. 118]) we assume that in an ID the tape must be blank except for some finite numbers of squares. If we remove this restriction the (...) UH becomes the immortality problem (IP). The UH should not be confused with the initialised uniform halting problem (whether or not a TM has an immortal ID when started in a specified state) which can easily be shown to be undecidable (see e.g. Minsky [3, p. 151]).

This commentary provides experimental data in support of the critical role of capsaicin-sensitive primary afferent fibers in the initiation and maintenance of pathological pain. The demonstration of capsaicin-induced, centrally-evoked cutaneous hyperalgesia, and of neuroplastic changes elicited by the degeneration of C-fiber primary afferent terminals following peripheral nerve damage, indicates a significant contribution of capsaicin-sensitive sensory ganglion neurons in the development of pathological pain conditions.

Istvan Bibó was the clandestine politological authority during the late Kadar period, and was rediscovered after the fall of communism. The essay examines and reconstructs the notions of elite and legitimation in Bibó''s political philosophy. As a young thinker he confronted the value crisis between the two world wars. He was influenced by Oswald Spengler''s and Ortega y Gasset''s theories of elites. The essay analyses the similarities and differences in their views. In Bibó''s conceptual world, the theory of elites is (...) connected with the issue of legitimation, because in his opinion the crisis of elites always results in a crisis of legitimation. Bibó''s analysis of elites, their social responsibilities as well as the types of legitimization are highly instructive for us since they help us rethink our conceptions of the social roles of elites and political legitimation under conditions of globalisation.

This original research paper discusses Bishop Albert Bereczky’s (1893-1966) first contacts with revivalism, especially his spiritual conversion experience during his adolescent years. Albert Bereczky, Bishop of the Danubian Church District from 1948 to 1958, was one of the most significant, and yet controversial persons of the Reformed Church in Hungary during the 20th Century. From a popular preacher of the Revival Movement of the 1920s, church planter of the 1930s, rescuer of Jews during the War, he became the tool of (...) state interest of the Communist regime in the 1950s. This paper sorts out the origins of his turn to the revival movement, like his troubled childhood, the emotional and financial insecurity of an illegitimate child, his troubled relationship with his biological father, the positive example of his stepfather, and his deviant adolescence behavior. By showing examples of his personal accounts the paper discusses whether Bereczky went through a ‘sudden’ or a ‘gradual’ conversion experience. (shrink)

In environmental ethics, there has been too little attention to the question of why changes in environmental beliefs do not simply result in changes in behavior, given that this gap between belief and behavior is widespread. In this essay, I argue that two forms of inaction that exhibit this gap can be helpfully analyzed by reading them in terms of a Lutheran account of sin. To make the argument, I distinguish seven forms of and reasons for inaction, from which I (...) pull out two “privileged” forms of inaction that characterize people who could act and yet do not. Using psychological and sociological research, I interpret these two forms of inaction as, on the one hand, people’s attempts at securing righteousness and, on the other hand, people’s terrorized consciences in response to the complexity and gravity of climate change. I end suggesting a turn to justification within Christian environmental ethics. (shrink)

If any nature of science perspective is to be incorporated in science-related curricula, it is hard to imagine a satisfactory didactic toolkit that neglects the social studies of science, the academic field of study of the institutional structures and networks of science. Knowledge production takes place in a world populated by actors, instruments, and ideas, and various epistemic cultures are responsible for providing the concepts, abstractions, and techniques that slowly trickle down the information pathways to become stabilized in university curricula (...) or ossified in high-school science, losing much of the tacit knowledge along the way that enabled the production of knowledge in the first place. The discussion of the sociology of science and the sociology of scientific knowledge is followed by a short overview of recent approaches in science studies and the studies of expertise. (shrink)

Based on the existence of polysemy (e.g., lunch can refer to both food and events), it is argued that central tenets of externalist semantics and Fodorian concept atomism, an externalist theory on which words lack semantic structure, are unsound. We evaluate the premise that these arguments rely on—that polysemous words have separate, finer‐grained senses. We survey the evidence across psychology and linguistics and argue that it shows that polysemy does not exist, at least not in this “sense”. The upshot is (...) that if polysemy does not exist, it cannot pose a problem for atomism or externalism. (shrink)

We explain the general significance of integer-based descriptors for natural shapes and show that the evolution of two such descriptors, called mechanical descriptors (the number _N_(_t_) of static balance points and the Morse–Smale graph associated with the scalar distance function measured from the center of mass) appear to capture (unlike classical geophysical shape descriptors) one of our most fundamental intuitions about natural abrasion: shapes get monotonically _simplified_ in this process. Thus mechanical descriptors help to establish a correlation between subjective and (...) objective descriptors of perceived objects. (shrink)

Plato claimed that the regular solids are the building blocks of all matter. His views, commonly referred to as the geometric atomistic model, had enormous impact on human thought despite the fact that four of the five Platonic solids can not fill space without gaps. In this paper we quantify these gaps, showing that the errors in Plato’s estimates were quite small. We also develop a mean field approximation to convex honeycombs using a generalized version of Plato’s idea. This approximation (...) not only admits to view convex mosaics in$$d=3$$d=3dimensions as a continuum but we also find that it is quite accurate, showing that Plato’s geometric intuition may have been remarkable.

We will study the class RSA of -dimensional representable substitution algebras. RSA is a sub-reduct of the class of representable cylindric: algebras, and it was an open problem in Andréka [1] that whether RSA can be finitely axiomatized. We will show, that the answer is positive. More concretely, we will prove, that RSA is a finitely axiomatizable quasi-variety. The generated variety is also described. We note that RSA is the algebraic counterpart of a certain proportional multimodal logic and it is (...) related to a natural fragment of first order logic, as well. (shrink)

Deindustrialization is a major burden on workers’ health in many countries, calling for theoretically informed sociological analysis. Here, we present a novel neoclassical sociological synthesis of the lived experience of deindustrialization. We conceptualize industry as a social institution whose disintegration has widespread implications for the social fabric. Combining Durkheimian and Marxian categories, we show that deindustrialization generates ruptures in economic production, which entail job and income loss, increased exploitation, social inequality, and the disruption of services. These ruptures spill over to (...) the field of social reproduction, generating material deprivation, job strain, fatalism, increased domestic workload, anomie, community disintegration, and alienation. These ruptures in social reproduction are sources of psychosocial stress, through which deindustrialization gets embodied as ill health and dysfunctional health behavior. We substantiate this framework through the extensive qualitative thematic analysis of 82 life history interviews in Hungary’s rust belt. (shrink)

A Critical Notice of Thomas KjellerJohansen, Plato’s Natural Philosophy. A Study of the Timaeus-Critias.

In recent articles in this journal Benoit Gaultier and John Biro have argued that the original Gettier cases and the ones closely modelled on them fail, and the reason for the failure is that the subject in these cases does not actually have the belief that would serve as a counterexample to the justified-true-belief analysis of knowledge. They claim that if our evidence pertains to a particular individual (as in the first case) or to the truth of one of the (...) disjuncts (as in the second case), we do not genuinely believe the existential generalization or the disjunction which logically follows. I will challenge their arguments and suggest that our unwillingness to assert the existential generalization or the disjunction under these conditions does not stem from lack of belief but from pragmatic principles.

The concept of the “End of History” was originally developed by G. W. F. Hegel in the Phenomenology of the spirit in 1806 (Hegel, 2018). The concept can be closely related to a utopia, the completion of the work of philosophers, and the creation of a perfect framework of the finished system of ideas. Hegel had a lot of influence on Western philosophy with the development of this idea and on Marx, who obviously thought of history in dialectic terms. However, (...) he developed the idea of “communism”, which would have been a state of humankind very similar to the concept of Hegel, with no class differences and no opiates of the people—and no place for further development (Marx & Engels, 2002). The “End of History” is based on this theoretical viewpoint that mankind has reached the final and most advanced form of societal development. However, the theorists and their intellectual followers both have to realize a painful way that the phenomenon can only be attained preliminarily. It proves to be a utopia. (shrink)

Moreover, if is saturated and the set of its locally finite automorphisms is dense (in particular, if is saturated and has weak generics), then the theory of is amenable. (shrink)

Through the example of a paradigmatic deliberative speech from classical oratory, the paper addresses two fundamental questions of teaching rhetorical reasoning. First, the paper shows that a speech from ancient Greek and Roman political or judicial oratory could provide effective means to teach a variety of argumentation skills, the recognition of fallacies and an awareness of biases in the target audience. Second, the paper uses the speech to consider an elusive problem of rhetorical or critical reasoning instruction, namely how students (...) may use historical models to adapt their knowledge of a case to real-life situations, where a large number of uncertain variables demands a constant awareness of the conditions affecting the audience`s decision and may require a swift change in the argumentative strategy. The paper will argue that the application of a new model of strategic reasoning called heuristic rhetoric to Cicero`s speech could illustrate a workable solution to both problems. (shrink)
