We examine some of Connes’ criticisms of Robinson’s infinitesimals starting in 1995. Connes sought to exploit the Solovay model S as ammunition against non-standard analysis, but the model tends to boomerang, undercutting Connes’ own earlier work in functional analysis. Connes described the hyperreals as both a “virtual theory” and a “chimera”, yet acknowledged that his argument relies on the transfer principle. We analyze Connes’ “dart-throwing” thought experiment, but reach an opposite conclusion. In S , all definable sets of reals are (...) Lebesgue measurable, suggesting that Connes views a theory as being “virtual” if it is not definable in a suitable model of ZFC. If so, Connes’ claim that a theory of the hyperreals is “virtual” is refuted by the existence of a definable model of the hyperreal field due to Kanovei and Shelah. Free ultrafilters aren’t definable, yet Connes exploited such ultrafilters both in his own earlier work on the classification of factors in the 1970s and 80s, and in Noncommutative Geometry, raising the question whether the latter may not be vulnerable to Connes’ criticism of virtuality. We analyze the philosophical underpinnings of Connes’ argument based on Gödel’s incompleteness theorem, and detect an apparent circularity in Connes’ logic. We document the reliance on non-constructive foundational material, and specifically on the Dixmier trace −∫ (featured on the front cover of Connes’ magnum opus) and the Hahn–Banach theorem, in Connes’ own framework. We also note an inaccuracy in Machover’s critique of infinitesimal-based pedagogy. (shrink)

Cílem studie je zodpovědět otázku, co znamená v interpretujících humanitních či sociálních vědách zkoumat narativně. Interpretace je pojata jako explikace utváření významu. V návaznosti na toto pojetí je identifikována řada interpretačních dilemat. V tomto kontextu je uveden narativní přístup jako řešení těchto dilemat. Je pojednáno o povaze narativní perspektivy, o vztahu narativity a zkušenosti a o povaze narativních dat. Narativní výzkum je chápán jako rekonstrukce způsobů, jakými je utvářen význam narativními prostředky. Narativní interpretace umožňuje pohybovat se pružně a efektivně: 1) (...) mezi explicitními daty a exemplifikačními schématy, 2) mezi jedincem a kulturou, 3) mezi hermeneutikou podezření a hermeneutikou důvěry, 4) mezi částmi a celkem, 5) mezi obsahem a formou, 6) mezi strukturou a funkcí.

The article deals with the question of correct reconstruction of and solutions to the ancient paradoxes. Analyzing one contemporary example of a reconstruction of the so-called Crocodile Paradox, taken from Sorensen’s A Brief History of Paradox, the author shows how the original pattern of paradox could have been incorrectly transformed in its meaning by overlooking its adequate historical background. Sorensen’s quoting of Aphthonius, as the author of a certain solution to the paradox, seems to be a systematic failure since the (...) time of Politiano’s erroneous attributing it to Aphthonius. In the conclusion, the author claims that neglecting the historical background of the ancient paradoxes into account, we are neither able to evaluate their modern interpretations as adequate nor their solutions as successful.

The article deals with some items of Gödelian time travel problem well-known as an illustration of a specific kind of causality paradox. Its first part presents “the travel into the past” according to several recent physical hypotheses, which, from theoretical standpoint, seem to make such an idea possible. The familiar concept of backward causation is also discussed; we need to accept and develop it, if we wish to escape this type of time-travel paradoxes. The second part of the contribution is (...) devoted to philosophical interpretations of the precedence in order of cause and effect, and of the relation between temporal and causal order. The author claims, that if we wish to save coherent picture of nature, it is necessary to revise the concept of causality to make it compatible with the concept of backward causation. (shrink)

The Lazy Argument, as it is preserved in historical testimonies, is not logically conclusive. In this form, it appears to have been proposed in favor of part-time fatalism (including past time fatalism). The argument assumes that free will assumption is unacceptable from the standpoint of the logical fatalist but plausible for some of the nonuniversal or part-time fatalists. There are indications that the layout of argument is not genuine, but taken over from a Megarian source and later transformed. The genuine (...) form of the argument seems to be given in different form and far closer to Megarian logical fatalism and its purpose is not to defend laziness. If the historical argument has to lead to a logically satisfactory solution, some additional assumptions and additional tuning is needed. (shrink)

We analyzed remarkable stories linked to the famous Anatoly Vlasov equations in plasma physics. Their creation, modification, and application are interesting from a scientific viewpoint. We also show the relations between those equations dealing with electromagnetism and analogous Jeans equations describing, in particular, gravitational instability in astrophysics. The second half of the essay is devoted to the controversies and political struggle in Soviet (before 1991) and Russian (after 1991) physical communities related to Vlasov’s personality, career, and posthumous recognition. The never-ending (...) destructive influence of Russian totalitarianism on science is demonstrated. (shrink)

The paper deals with the possible readings of The Reaper Argument premisses. Some conjectures related to the Stoics’ alleged proof of the argument are discussed.

In the current philosophical literature, determinism is rarely defined explicitly. This paper attempts to show that there are in fact many forms of determinism, most of which are familiar, and that these can be differentiated according to their particular components. Recognizing the composite character of determinism is thus central to demarcating its various forms.

The paper has two objectives: to introduce the fundamentals of a triplet model of a concept, and to show that the main concept models may be structurally treated as its partial cases. The triplet model considers a concept as a mental representation and characterizes it from three interrelated perspectives. The first deals with objects (and their attributes of various orders) subsumed under a concept. The second focuses on representing structures that depict objects and their attributes in some intelligent system. The (...) third concentrates on the ways of establishing correspondences between objects with their attributes and appropriate representing structures. (shrink)

Fundamental Science is undergoing an acute conceptual-paradigmatic crisis of philosophical foundations, manifested as a crisis of understanding, crisis of interpretation and representation, “loss of certainty”, “trouble with physics”, and a methodological crisis. Fundamental Science rested in the "first-beginning", "first-structure", in "cogito ergo sum". The modern crisis is not only a crisis of the philosophical foundations of Fundamental Science, but there is a comprehensive crisis of knowledge, transforming by the beginning of the 21st century into a planetary existential crisis, which has (...) exacerbated the question of the existence of Humanity and life on Earth. Due to the unsolved problem of justification of Mathematics, paradigm problems in Computational mathematics have arisen. It's time to return ↔ Into Dialectics. The solution to the problem of the foundations of Mathematics, and therefore knowledge in general, is the solution to the problem of modeling (constructing) the ontological basis of knowledge - the ontological model of the primordial generating process. The idea and model of the primordial generating process, its ontological structure directs thinking to the need for the introduction of superconcept → ontological (cosmic, structural) memory, concept-attractor, supercategory, substantial semantic core of the scientific picture of the world of the nuclear-ecological-information age.

Physical theories are complex and necessary tools for gaining new knowledge about their areas of application. A distinction is made between abstract and practical theories. The last are constantly being improved in the cognitive activity of professional physicists and studied by future physicists.

Readers should decide whether this option is useful for their understanding of the philosophy of physics, as well as other (...) philosophies of particular sciences. (shrink)

Comparative philosophical studies can seek to fit some Eastern patterns of thought into the general philosophical framework, or, on the contrary, to improve understanding of Western ones through the view "from abroad". I try to hit both marks by means of establishing, firstly, the parallels between Indian versions of theodicy and the Hellenic and Christian ones, then by defining to which of five types of Western theodicy the Advaita-Vedanta and Nyaya versions belong and, thirdly, by considering the meaning of the (...) fact that some varieties of Western theodicy, like the explanation of evil by free will and divine dispensation aiming at the improvement of man, have Indian counterparts while others lack them. Some considerations concerning the remainders of primordial monotheisms ("an argument from theodicy") under the thick layers of other religious world-outlooks are also offered to the reader at the end of the article.

Physicalism as a metaphysical or ontological concept has maintained a dominant position since the second half of the last century to the present day. The claim that everything is physically constituted often accompanies microphysical reductionism, which assumes the existence of fundamental laws to which everything is reducible. In this context, a question regarding the status and possible autonomy of the laws of special sciences arises. The article focuses on the basic philosophical discussions between the strong, weak, and non-reductive physicalism that (...) treat the laws of special sciences in different ways, but none of which can be considered sufficiently convincing and successful. The article seeks to prove the existence of a universal mechanism that leads to the emergence of new and complex entities and regulations of their behaviour, thus justifying the autonomous status of special sciences and laws.

The work tends to point out the deficiency of some opinions claiming simplified presentation of the promise as the act that directly rise obligation for the promisor. Promises, either in the moral or legal sphere, are based on communication and so form an order of dependent steps that indicates their procedural nature. These characteristics may differ to a lesser extent, depending on the legal systems, moral norms of the society and its technical level and its needs. In all these cases, (...) however, the procedural characteristics of promises, especially in conditional promises, as well as the promises in contractual relations, persists. In our analysis we wish to show that the consistent conception of promise has to take into account a step of acceptance. The outcome of this approach relativizes a strong distinction between promise and offer. (shrink)

The Russian academic theological tradition, scarcely known to the West, was the only milieu wherein the development of philosophy of religion in the pre-revolutionary Russia was under way. Philosophical investigation of the phenomenon of religion was being elaborated in the apologetic context, i.e. in critical analysis of non-theistic conceptions of the origin and essence of religion, and the figure of Friedrich Schleiermacher, with his reduction of religion firstly to cosmic feelings and later to the feeling of the ontological dependence, occupied (...) an invariable place in this analysis. The paper deals with critical comments on Schleiermacher’s Speeches on Religion and Christian Faith made by Victor Kudryavtsev-Platonov and his followers, which are being parsed in turn, as well as with historical links of the later Schleiermacher with phenomenology of religion and typological affinities of the earlier Schleiermacher with the theology of religious pluralism.

The scheme for classifications of concepts is introduced. It has founded on the triplet model of concepts. In this model a concept is depicted by means of three kinds of knowledge: a concept base, a concept representing part and the linkage between them. The idea of triplet classifications of concepts is connected with a usage of various specifications of these knowledge kinds as classification criteria.

Článek reflektuje Hayekovy výklady o povaze pravidel. Ukazuje, že jeho pojetí pravidel je extrémně široké a vazba mezi pravidly a pravidelnostmi je nepřijatelně úzká. Následně je nastíněno alternativní - užší - vymezení pojmu pravidla. Nakonec je podrobeno kritice Hayekovo příliš úzké chápání pojmu normativních pravidel a je navrženo jeho širší vymezení.

David Miller v pracích Critical Rationalism a Out of Error se jako jeden z mála Popperových žáků snaží nejen o vysvětlení a obhájení Popperova kritického racionalismu, ale zároveň i o jeho další rozvinutí.

Uvedená stať se zaměřuje právě na tuto otázku existence tzv. „dobrých důvodů“ ve spojení s racionalitou a racionálním rozhodováním a ukazuje, že Millerův požadavek neexistence „dobrých důvodů“ je nejen příliš (...) radikální, ale i nepřijatelný z hlediska Popperova nebo Musgravova pojetí kritického racionalismu.

This article aims to show that it is impossible to put Cicero’s testimonies regarding The Fabius Argument in a consistent inferential order. Either we must suppose that additional premises are tacitly assumed in the text or we must com-pare it with other sources, which leads to inconsistencies in the proof’s reconstruction. Cicero’s reconstruction of the progression of the argument has formal shortcomings, and the paper draws attention to some of these deficiencies. He interpreted sources in a revised and intentionally simplified (...) way, with the aim of undermining the views of his opponents, casting them as inconsistent and similar to views held by Diodorus. Rather than being a consistently interpreted argument faithfully transcribed from the Stoic sources, Cicero’s Fabius Argument is ultimately anti-Stoic. (shrink)

One of the main and currently dominating attempt in theories of philosophical psychology is the way of describing psychological facts as cognitive state of affairs or mental events which could be individuated by the same means as it were natural species. This idea resulted from incapability of the " folk" psychology to give complete and satisfactory scientific explanation by the intentionality approach. The author claims that many certain advantages of the cognitive theories could be disputable if we try to consistently (...) analyze the ways of describing and individuation of entities in such "deeper" theories. And, especially if we can recognize them as spatiotemporally restricted (i .e. historical) entities. This alternative case could be, as it seems, theoretically more appropriate to their subjects: particular thoughts, believes, desires, representations and other mental events would be individuated as genealogically reconstructed subjects which forms potentially stronger explanatory power than in the case of explanations given by covering laws and in accordance with the presupposition of nomological necessity.

The triplet model treats a concept as complex structure that expresses three kinds of information. The first is about entities subsumed under a concept,their properties and relations.

The application of triplet models to generalization and development of concept models in philosophy, logic, cognitive psychology, cognitive science, linguistics, artificial intelligence has (...) been demonstrated. The componential structure of the triplet model and extended concept classification have been given. Theoretical considerations are combined with historical case-studies of concept history.

In the opening lines of this article it is claimed that history is a discipline taking role as part of unique body of science. The concept of scientific rationality is presented as the criterion of demarcation between science and pseudoscience. From this statement as a starting point, it follows that the methodological grounds for scientific predictions are common for all scientific disciplines. Different aspects of scientific predicting are critically examined: thesis of symmetry, determinism and predictability, indeterminism and predictability, reflexivity of (...) predictions, prediction of novelty and progress, predictions in relation to the time of their uttering, the prediction sketch, truthfulness and regularity in implying prediction, and predictability of human actions. In the concluding section, the author admits of the possibility of constructing the theory of history, opposed to eschatological philosophy of history, as a predictive theory with a scientific basis and a theory whose specifications limit its misuse in practice.

Essays on Aristotle's Sea-Battle, Lazy Argument, Argument Reaper, Diodorus' Master Argument -/- The book is devoted to the ancient logical theories, reconstruction of their semantic proprieties and possibilities of their interpretation by modern logical tools. The Ancient arguments are frequently misunderstood in modern interpretations since authors usually have tendency to ignore their historical proprieties and theoretical background what usually leads to a quite inappropriate picture of the argument’s original form and mission. Author’s primary intention was to draw attention to the (...) complexity of some historical arguments and to the theoretical context in which arguments were created, circulated, developed, and finally tuned. Four well-known ancient arguments – with a common central subject related to the future contingencies problem – are reconstructed from available historical sources: “The Sea Battle”, which is drawn from Aristotle’s treatise De Interpretatione; two arguments, usually ascribed to the Stoics, “The Lazy Argument” and “The Reaper”; “The Master Argument” of the Megarian philosopher Diodorus. Arguments are linguistically and semantically detaily analyzed, formally presented by reflecting some relevant corresponding hypotheses based on physical or logical theories of their ancient authors, and finally covered by appropriate logical tools familiar to a modern reader. Two appendices are added at the closing part of the book. One covering some assumptions relevant for understanding of rival streams in ancient theories of meaning related to the nature of names and naming; the other is devoted to the ancient understanding of logical proposition and attempts to find an adequate Latin translation of the Greek delicate philosophical term “ἀξίωμα”.

This paper develops a counterexample to Davidson’s elaborate model of conventionless communication, first articulated in his (1986) and defended in his (1994a). The first part contains an analysis of the model and its assumptions. Then, in a second part, I present a case focused around the concept of overhearing. It subtracts active interaction from the model and reveals that, under these novel conditions, communication makes further demands on it, namely conformity of the prior interpretive theory of all but one of (...) the interacting members. The analysis of the case concludes, in the third part, that Davidson’s account is unsuited for explaining communication where active interpretive interactions are excluded. And hence, for describing the full range of our linguistic competence. (shrink)
