Prominent thinkers such as Jurgen Habermas and Michael Sandel are warning that biomedical enhancements will undermine fundamental political values. Yet whether biomedical enhancements will undermine such values depends on how biomedical enhancements will function, how they will be administered and to whom. Since only few enhancements are obtainable, it is difficult to tell whether these predictions are sound. Nevertheless, such warnings are extremely valuable. As a society we must, at the very least, be aware of developments that could have harmful (...) consequences. Indeed, if important values were to be jeopardized, we should take appropriate measures to protect them. This paper focuses on four central values: solidarity, personal responsibility, equality and autonomy. It delineates the conditions under which biomedical enhancements would undermine these values. It also details the circumstances under which these values would be unaffected by enhancements as well as those under which they would be promoted. Specifying these conditions is valuable; it would enable society to prepare appropriate ethical guidelines and policy responses in advance. (shrink)

The main focus of the book is the presentation of the 'inertial' view of population growth. This view provides a rather simple model for complex population dynamics, and is achieved at the level of the single species without invoking species interactions. An important part of this account is the maternal effect. Investment of mothers in the quality of their daughters makes the rate of reproduction of the current generation depend not only on the current environment, but also on the environment (...) experienced by the previous generation.

We present four new change detection methods that create an automated change map from a probability map. In this case, the probability map was derived from a 3D model. The primary application of interest is aerial photographic applications, where the appearance, disappearance or change in position of small objects of a selectable class (e.g., cars) must be detected at a high success rate in spite of variations in magnification, lighting and background across the image. The methods rely on an earlier (...) derivation of a probability map. We describe the theory of the four methods, namely Bernoulli variables, Markov Random Fields, connected change, and relaxation-based segmentation, evaluate and compare their performance experimentally on a set probability maps derived from aerial photographs.

This article compares the sections on the qualities desirable in a wife in Abū Ḥāmid al-Ghazālī’s Iḥyāʾ ʿulūm al-dīn and Bar Hebraeus’s Ethicon, which the West Syrian writer modeled on al-Ghazālī’s work. The article first establishes that al-Ghazālī based his profile of the ideal wife on a jurisprudential discussion of the topic by his teacher, Imām al-Ḥaramayn al-Juwaynī, expanding it, however, by adding anecdotes from Sufi literature and reasoned arguments on how “the good wife” will best facilitate her husband’s devotion (...) to God. The article then moves to consider how Bar Hebraeus appropriates, reconfigures, and reframes as Christian teaching al-Ghazālī’s discussion. Finally, the article argues that the similarity between the two texts demonstrates that both carve out a particular notion of male piety intelligible and resonant in their different religious traditions and in the broader monotheistic culture of the premodern Middle East.

RESUMEN Largamente desatendida o malinterpretada, la noción de caos en la filosofía de Nietzsche es una pieza constitutiva de la particular concepción del ser que este autor habría dejado apenas esbozada. El artículo se propone elaborar este concepto en la obra nietzscheana, siguiendo algunas de las metáforas que lo iluminan. Desde allí se busca plantear los rasgos centrales de una ontologia del caos, de sesgo no metafísico, que, al afirmar el carácter acontecimental de la realidad, puede verse como precursora de (...) la ontología hermenéutica contemporánea. ABSTRACT The notion of chaos, which has long been neglected or misinterpreted, is a constitutive element of a peculiar conception of being that the philosopher only had time to outline. The objective of this article is to elaborate on this concept in Nietzschean philosophy, guided by some of the metaphors that shed light on it. This serves as the basis to set forth the main characteristics of a non-metaphysical ontology of chaos that asserts the eventful nature of reality and can thus be seen as a precursor of contemporary hermeneutic ontology.

The Many-Worlds Interpretation (MWI) is an approach to quantum mechanics according to which, in addition to the world we are aware of directly, there are many other similar worlds which exist in parallel at the same space and time. The existence of the other worlds makes it possible to remove randomness and action at a distance from quantum theory and thus from all physics.

Analyzes principal forces that determined the direction of Camus' thought on ethics and political values.

This is a philosophical paper in favor of the many-worlds interpretation of quantum theory. The necessity of introducing many worlds is explained by analyzing a neutron interference experiment. The concept of the “measure of existence of a world” is introduced and some difficulties with the issue of probability in the framework of the MWI are resolved.

What is the most important reason for using Computer Vision methods in humanities research? In this article, I argue that the use of numerical representation and data analysis methods offers a new language for describing cultural artifacts, experiences and dynamics. The human languages such as English or Russian that developed rather recently in human evolution are not good at capturing analog properties of human sensorial and cultural experiences. These limitations become particularly worrying if we want to compare thousands, millions or (...) billions of artifacts—i.e. to study contemporary media and cultures at their new twenty-first century scale. When we instead use numerical measurements of image properties standard in Computer Vision, we can better capture details of a single artifact as well as visual differences between a number of artifacts–even if they are very small. The examples of visual dimensions that numbers can capture better then languages include color, shape, texture, contours, composition, and visual characteristics of represented faces, bodies and objects. The methods of finding structures and relationships in large numerical datasets developed in statistics and machine learning allow us to extend this analysis to very big datasets of cultural objects. Equally importantly, numerical image features used in Computer Vision also give us a new language to represent gradual and continuous temporal changes—something which natural languages are also bad at. This applies to both single artworks such as a film or a dance piece and also to changes in visual characteristics in millions of artifacts over decades or centuries. (shrink)

It is argued that the many-worlds interpretation is by far the best interpretation of quantum mechanics. The key points of this view are viewing the wave functions of worlds in three dimensions and understanding probability through self-locating uncertainty.

Progressions of iterated reflection principles can be used as a tool for the ordinal analysis of formal systems. We discuss various notions of proof-theoretic ordinals and compare the information obtained by means of the reflection principles with the results obtained by the more usual proof-theoretic techniques. In some cases we obtain sharper results, e.g., we define proof-theoretic ordinals relevant to logical complexity Π1 0 and, similarly, for any class Π n 0 . We provide a more general version of the (...) fine structure relationships for iterated reflection principles (due to U. Schmerl [25]). This allows us, in a uniform manner, to analyze main fragments of arithmetic axiomatized by restricted forms of induction, including IΣ n , IΣ n − , IΠ n − and their combinations. We also obtain new conservation results relating the hierarchies of uniform and local reflection principles. In particular, we show that (for a sufficiently broad class of theories T) the uniform Σ1-reflection principle for T is Σ2-conservative over the corresponding local reflection principle. This bears some corollaries on the hierarchies of restricted induction schemata in arithmetic and provides a key tool for our generalization of Schmerl's theorem. (shrink)

The article examines the phenomenon of conformism in the context of socialist realism, which for a long time was the main direction for the Soviet art sphere. Conformism is interpreted as an effective way for the artist to optimize relations with the authorities and society, giving the opportunity for social self-preservation. Conformism is a kind of strategy for artists, thanks to which they manage to achieve their creative goals and successfully exist within the established cultural framework. The author of the (...) article argues that conformism helped artists who put their creativity at the service of socialist realism to find some basis for their activities, because socialist realism did not initially have such a basis. The author comes to the conclusion that in the conditions of constant transformation of cultural requirements and the need to fully comply with them, conformism becomes for the artist not just a tactic in achieving creative goals, but also a kind of self-defense mechanism that allows to preserve mental and physical health. The most successful Soviet artists were able to realize their talent by creating many bright works of art due to the fact that they created precisely in the mainstream of socialist realism, and if it were not for it, perhaps the world would never have known about some outstanding Soviet artists, as well as not seen their works of art, since the realization of Soviet artists in another cultural environment might well not have taken place.

In the article, through the prism of the existential philosophy of S. Kierkegaard, K. Jaspers, G.-G. Gadamer and J.-P. Sartre, as well as the theory of ideology of K. Manheim, the personality of the main character of M. Y. Lermontov's drama "Masquerade" – Arbenin is analyzed. The author of the article claims that Arbenin is in a state of existential despair and finds himself in a borderline situation. At the same time, in the drama "Masquerade", the ideals of Romanticism are (...) reduced to a post-Romantic ideology. Lermontov does this intentionally in order to condemn the ideological perversion of the ideals of romantic culture. The drama also focuses on the general cultural border situation: how to protect yourself from the temptations of ideology at a time when existing ideals and values are disappearing. The author of the article comes to the conclusion that in "Masquerade" Lermontov praises the romantic ideals of rebellious spirit and will, transcendent love and insight, even when he shows the dangers of turning these ideals into ideology. But "Masquerade" is not a romantic drama. This is a drama about romanticism, that is, about how the ideals of romantic culture can be perverted into an ideology that deceives and destroys people, destroying their unique existence, instead of elevating them. "Masquerade" is a variant of Lermontov's reaction to the difficulties that arose in his post–romantic, transitional time. Conveying his admiration for the ideals of romantic culture, Lermontov embodies one of the types of reaction to the realization of the decline of these ideals – the stereotypical reduction of the romantic worldview and values to a set of ideological concepts. But by portraying Arbenin, Lermontov hints at the possibility of recognizing that the worldview and values of Romanticism are losing their authority and integrity and that turning them into an ideology does not compensate for this loss. We need to find a new worldview, new values, new ideals. (shrink)

The article examines the historiosophical reflections of F. I. Tyutchev, presented in his treatises, letters, poems, and substantiates the idea that Tyutchev does not proclaim slogans of either Slavophil or Westernist doctrines, but creates an original imperial ideology. Tyutchev views Russia as an equal and integral part of Europe, linking the existence of the empire with the development of the European spirit in Russia. The main criterion for the existence of the empire is unity. If it does not exist, then (...) the state as an empire cannot exist. Tyutchev treated Orthodoxy as a historiosophical category. He bases his concept of the historical process on the traditions of Eastern Christianity and the legacy of the Byzantine Empire. In the idea of an empire based on Christian principles, Tyutchev sees the best system of statehood. For Tyutchev, the Russian people and Orthodoxy play a major role in the transformation of the world. In the concept of state and power, the categories of Christian ethics are especially important for Tyutchev, which, in his opinion, were not really relevant for the upper strata of society and representatives of the Russian government. The poet calls power "godless", claiming that it does not come from God, but is based on its material power, without recognizing a higher Divine authority over itself. The reason for the "godlessness" of the authorities was the separation from the Russian people and their national traditions and the departure from the historical past of "Holy Russia". This, from Tyutchev's point of view, is the main existential problem of Russia. Tyutchev's concept of empire was not a reproduction of the realities of the political life of Russia in the XIX century, but was an attempt to answer how the state should be built. Tyutchev's ideal of the Russian state is based on a society united by a single Christian faith. (shrink)

The article presents an analysis of the existential paradigm of M. Lermontov's creativity in the light of the existential theories of S. Kierkegaard and K. Jaspers, which is considered in the context of the cultural transition in Russian literature of the 1830s-1840s. It is argued that Lermontov radically changed the nature of his literary activity by the mid-1830s, overcoming his own existential ambivalence and abandoning the subjective emotionality and exoticism of his youthful poetry in favor of objective observations and research (...) of the surrounding world. Lermontov was aware of his existential ambivalence and sought to overcome this state in order to achieve cultural integrity, which should be considered as one of his main values. Lermontov's works reflect the concept of integrity as the integration of culture through a set of prevailing norms and ideals, as well as the feeling that this integrity was disintegrating in transitional times. This state of affairs caused a sense of disintegration in Lermontov, which is similar to the borderline situation of Jaspers. Lermontov's works illustrate the loss of cultural ideals with the decline of Romanticism. But rejecting the ideals of Romanticism, Lermontov conveys the feeling that post-Romantic disappointment generated cynicism and distorted thinking. The novel "The Hero of Our Time" has become the embodiment of such shortcomings. Lermontov's works do not belong to romanticism, nor to protorealism, nor to any combination of both. But Lermontov played his transitional role superbly. Not only did he raise questions about Romanticism that realism would later make its own, he also shed light on Romanticism itself and how it was fading. Lermontov showed how difficult it is for an artist who is aware of his own existential ambivalence to create and live in a transitional time devoid of a unifying sense of cultural integration and integrity, illustrating how badly a creative personality needs such integration and integrity.

A well-known result states that, over basic Kalmar elementary arithmetic EA, the induction schema for ∑n formulas is equivalent to the uniform reflection principle for ∑n + 1 formulas . We show that fragments of arithmetic axiomatized by various forms of induction rules admit a precise axiomatization in terms of reflection principles as well. Thus, the closure of EA under the induction rule for ∑n formulas is equivalent to ω times iterated ∑n reflection principle. Moreover, for k < ω, k (...) times iterated ∑n reflection principle over EA precisely corresponds to the extension of EA by k nested applications of ∑n induction rule.The above relationship holds in greater generality than just stated. In fact, we give general formulas characterizing in terms of iterated reflection principles the extension of any given theory by k nested applications of ∑n or Πn induction rules. In particular, the closure of a theory T under just one application of ∑1 induction rule is equivalent to T together with ∑1 reflection principle for each finite Π2 axiomatized subtheory of T.These results have closely parallel ones in the theory of subrecursive function classes. The rules under study correspond, in a canonical way, to natural closure operators on the classes of provably recursive functions. Thus, ∑1 induction rule precisely corresponds to the primitive recursive closure operator, and ∑1 collection rule, introduced below, corresponds to the elementary closure operator. (shrink)

Provability logic GLP is well-known to be incomplete w.r.t. Kripke semantics. A natural topological semantics of GLP interprets modalities as derivative operators of a polytopological space. Such spaces are called GLP-spaces whenever they satisfy all the axioms of GLP. We develop some constructions to build nontrivial GLP-spaces and show that GLP is complete w.r.t. the class of all GLP-spaces.

Historically, appearance of the quantum theory led to a prevailing view that Nature is indeterministic. The arguments for the indeterminism and proposals for indeterministic and deterministic approaches are reviewed. These include collapse theories, Bohmian Mechanics and the many-worlds interpretation. It is argued that ontic interpretations of the quantum wave function provide simpler and clearer physical explanation and that the many-worlds interpretation is the most attractive since it provides a deterministic and local theory for our physical Universe explaining the illusion of (...) randomness and nonlocality in the world we experience.

This paper describes two quotation strategies employed by speakers of Nanti, one involving grammaticalized quotatives and another involving complement-taking verbs of saying, and examines the consequences of the pragmatic differences between these strategies for two key questions in the study of evidentiality: first, the importance of degree of grammaticalization in delimiting ‘evidentials’; and second, the importance of the analytical distinction between epistemic modal and ‘source of information’ evidential meanings. Nanti use of the two quotation strategies is specifically analyzed in the (...) context of self-quotation practices in order to isolate specific aspects of their pragmatics. This analysis shows that the lexical quotative strategy expresses that the quoted party is not only the source of the content of the utterance, but is also an ‘illocutionary source’, who is committed to the interactional force of the utterance, while the grammaticalized quotative strategy does not indicate such a commitment. The functional difference between lexical and grammatical quotative strategies in Nanti is compared with differences between lexical and grammaticalized quotative and reportive strategies found in other languages, and the Nanti results are found to be consistent with cross-linguistic tendencies towards functional differentiation of lexical quotative and reportives, on the one hand, and their grammaticalized counterparts, on the other. These facts, it is argued, motivate a distinction on functional grounds between grammaticalized reportives and quotatives and their lexical counterparts, supporting the use of grammaticalization as a criterion for distinguishing evidentials proper from evidential strategies. The commitment-augmenting function of the lexical quotative construction in Nanti self-quotation is then examined in light of the commitment-diminishing function commonly attributed to quotatives and reportives. It is argued that both types of commitment-modulating effects emerge as implicatures from the basic information and illocutionary source semantics of Nanti lexical quotatives, and from pragmatic reasoning based on whether the quoted party is first person or third person. The fact that both commitment-modulating functions of Nanti lexical quotatives are derived from semantics of lexical quotatives elements is argued to show that the distinction between information source and epistemic modal meanings, often taken to be a pivotal notional distinction in defining evidentiality as a grammatical category, is also essential to the proper analysis of the pragmatics of evidential strategies in discourse.

We suggest an algebraic approach to proof-theoretic analysis based on the notion of graded provability algebra, that is, Lindenbaum boolean algebra of a theory enriched by additional operators which allow for the structure to capture proof-theoretic information. We use this method to analyze Peano arithmetic and show how an ordinal notation system up to 0 can be recovered from the corresponding algebra in a canonical way. This method also establishes links between proof-theoretic ordinal analysis and the work which has been (...) done in the last two decades on provability logic and reflection principles. Because of its abstract algebraic nature, we hope that it will also be of interest for non-prooftheorists. (shrink)

It is argued that, although in the Many-Worlds Interpretation of quantum mechanics there is no ``probability'' for an outcome of a quantum experiment in the usual sense, we can understand why we have an illusion of probability. The explanation involves: a). A ``sleeping pill'' gedanken experiment which makes correspondence between an illegitimate question: ``What is the probability of an outcome of a quantum measurement?'' with a legitimate question: ``What is the probability that ``I'' am in the world corresponding to that (...) outcome?''; b). A gedanken experiment which splits the world into several worlds which are identical according to some symmetry condition; and c). Relativistic causality, which together with explain the Born rule of standard quantum mechanics. The Quantum Sleeping Beauty controversy and ``caring measure'' replacing probability measure are discussed. (shrink)

Social network structure has been argued to shape the structure of languages, as well as affect the spread of innovations and the formation of conventions in the community. Specifically, theoretical and computational models of language change predict that sparsely connected communities develop more systematic languages, while tightly knit communities can maintain high levels of linguistic complexity and variability. However, the role of social network structure in the cultural evolution of languages has never been tested experimentally. Here, we present results from (...) a behavioral group communication study, in which we examined the formation of new languages created in the lab by micro‐societies that varied in their network structure. We contrasted three types of social networks: fully connected, small‐world, and scale‐free. We examined the artificial languages created by these different networks with respect to their linguistic structure, communicative success, stability, and convergence. Results did not reveal any effect of network structure for any measure, with all languages becoming similarly more systematic, more accurate, more stable, and more shared over time. At the same time, small‐world networks showed the greatest variation in their convergence, stabilization, and emerging structure patterns, indicating that network structure can influence the community's susceptibility to random linguistic changes (i.e., drift).

Le messianisme fait à la fois partie des principaux articles de foi du Judaïsme et appelle en même temps son renversement lorsqu’il se réalise de manière effective. Le messianisme s’exprime alors à travers une critique de la loi comme impératif catégorique, étatique et particulariste exercée par une instance transcendante. Saint-Paul incarne très certainement le fer de lance de cette révolution messianique au fondement de l’universalisme. Cette inauguration d’une loi immanente au sujet destinée à supplanter la loi transcendante du Judaïsme se (...) prolonge à travers un certain nombre de figures de la modernité, notamment celles de Spinoza et Freud. Le messianisme n’est pas à entendre ici comme pure et simple trahison de la loi juive mais au contraire comme révélation d’une fracture qui lui appartient originellement. (shrink)

A well-known polymodal provability logic inlMMLBox due to Japaridze is complete w.r.t. the arithmetical semantics where modalities correspond to reflection principles of restricted logical complexity in arithmetic. This system plays an important role in some recent applications of provability algebras in proof theory. However, an obstacle in the study of inlMMLBox is that it is incomplete w.r.t. any class of Kripke frames. In this paper we provide a complete Kripke semantics for inlMMLBox . First, we isolate a certain subsystem inlMMLBox (...) of inlMMLBox that is sound and complete w.r.t. a nice class of finite frames. Second, appropriate models for inlMMLBox are defined as the limits of chains of finite expansions of models for inlMMLBox . The techniques involves unions of n -elementary chains and inverse limits of Kripke models. All the results are obtained by purely modal-logical methods formalizable in elementary arithmetic. (shrink)
