Many tasks in statistical and causal inference can be construed as problems of entailment in a suitable formal language. We ask whether those problems are more difficult, from a computational perspective, for causal probabilistic languages than for pure probabilistic (or “associational”) languages. Despite several senses in which causal reasoning is indeed more complex—both expressively and inferentially—we show that causal entailment (or satisfiability) problems can be systematically and robustly reduced to purely probabilistic problems. Thus there is no jump in computational complexity. (...) Along the way we answer several open problems concerning the complexity of well-known probability logics, in particular demonstrating the ${\exists \mathbb {R}}$ -completeness of a polynomial probability calculus, as well as a seemingly much simpler system, the logic of comparative conditional probability.

Kripke-style models with two accessibility relations, one intuitionistic and the other modal, are given for analogues of the modal systemK based on Heyting's prepositional logic. It is shown that these two relations can combine with each other in various ways. Soundness and completeness are proved for systems with only the necessity operator, or only the possibility operator, or both. Embeddings in modal systems with several modal operators, based on classical propositional logic, are also considered. This paper lays the ground for (...) an investigation of intuitionistic analogues of systems stronger thanK. A brief survey is given of the existing literature on intuitionistic modal logic.

Quantification is particularly seductive in times of global uncertainty. Not surprisingly, numbers, indicators, categorizations, and comparisons are central to governmental and popular response to the COVID-19 pandemic. This essay draws insights from critical data studies, sociology of quantification and decolonial thinking, with occasional excursion into the biomedical domain, to investigate the role and social consequences of counting broadly defined as a way of knowing about the virus. It takes a critical look at two domains of human activity that play a (...) central role in the fight against the virus outbreak, namely medical sciences and technological innovation. It analyzes their efforts to craft solutions for their user base and explores the unwanted social costs of these operations. The essay argues that the over-reliance of biomedical research on “whiteness” for lab testing and the techno-solutionism of the consumer infrastructure devised to curb the social costs of the pandemic are rooted in a distorted idea of a “standard human” based on a partial and exclusive vision of society and its components, which tends to overlook alterity and inequality. It contends that to design our way out of the pandemic, we ought to make space for distinct ways of being and knowing, acknowledging plurality and thinking in terms of social relations, alterity, and interdependence.

This article approaches the paradigm shift of datafication from the perspective of civil society. Looking at how individuals and groups engage with datafication, it complements the notion of “data politics” by exploring what we call the “contentious politics of data”. By contentious politics of data we indicate the bottom-up, transformative initiatives interfering with and/or hijacking dominant processes of datafication, contesting existing power relations or re-appropriating data practices and infrastructure for purposes distinct from the intended. Said contentious politics of data is (...) articulated in an array of practices of data activism taking a critical stance towards datafication. In data activism, data as mediators take a central role, both as part of an action repertoire or as objects of struggle in their own right. Leveraging social movement studies and science and technology studies, this theoretical essay argues that data activism can be mapped along two analytical dimensions: “data as stakes” vs. “data as repertoires”, and “individual practice vs. collective action”. Mapping action repertoires and tactics along these axes allows us to chart the potential emergence of a political data subject at the intersection of these two dimensions. This furthers our understanding of people’s engagement with data in relation to other forms of activism and existing work in social movement studies. It also helps us interpreting potential trajectories of contemporary social movements, as they increasingly interface with data, devices and platforms. (shrink)

Isabelle Stengers’ cosmopolitical proposal is an influential attempt by a European philosopher to transform the burdensome legacy of Western thought. Reconsidering her comprehensive engagement with the cosmology of the British mathematician and philosopher Alfred North Whitehead, this article reveals two concepts as foundational to Stengers’ cosmopolitics: civilization and commerce. While not usually associated with a critical political theory, in her development of what we call a commercial political ontology, Stengers explores the modes of inheriting these ostracized notions. By tracing the (...) genealogy of this political ontology back to Pericles’ first explicit defense of persuasion as a requisite for civilization, we argue that Pericles’ famous funeral oration provides the structure for Whitehead’s cosmology, and, ultimately, Stengers’ cosmopolitics. As such, we understand her cosmopolitical proposal as a dress rehearsal of a funeral eulogy for bourgeois society. (shrink)

The Kiki-Bouba effect comprises a relation between two abstract figures and two non-words: the star-shaped figure is called 'Kiki' and the rounded figure 'Bouba'. The effect is explained by a sound-vision synaesthesia: certain sounds are associated with certain shapes in a non-arbitrary manner.When we asked the participants to decide which of the two figures, the star-shaped or the rounded one, to call yin and which yang, some 85% choose the star-shaped figure as yin. There are previous cases of synaesthesia where (...) personality is attributed to numbers or letters. In our results, the word Kiki is overall happy, clever, small, thin, young, unpleasant, and nervous. The starshaped figure is overall clever, tall, small, slim, nervous, unpleasant, and upper-class. That is, the correspondence above all concerns the qualifying adjectives clever, unpleasant, and nervous, as well as the physical appearance small and thin. This brings us to the fat-thin effect. Cinema, literature, comics, and children's programmes are full of contrasting figures: Don Quixote and Sancho Panza, Laurel and Hardy , Asterix and Obelix, Tintin and Captain Haddock, Bert and Ernie , or the Spanish comic about very naughty twin boys called Zipi and Zape . Our main conclusion is that first names and last names are not entirely arbitrary. There is a correspondence between names and physical characteristics and concepts . The Kiki-Bouba effect is a semantic one. (shrink)

Recent discussion of the alleged adverse consequences of space colonization by Phil Torres in this journal is critically assessed. While the concern for suffering risks should be part of any strategic discussion of the cosmic future of humanity, the Hobbesian picture painted by Torres is largely flawed and unpersuasive. Instead, there is a very real risk that the skeptical arguments will be taken too seriously and future human flourishing in space delayed or prevented.

Ob množici del grških in rimskih piscev, ki so bila prevedena v slovenski jezik, je Livijeva Zgodovina doslej ostala nekako ob strani. Razen posameznih odlomkov ni bilo prevedenega nič.

Milan, David While esteemed Christian apologist C.S. Lewis ruefully puzzled over The Problem of Pain, the theologians invented their own word - 'theodicy' - to describe the futile attempts (to date) to resolve monotheism's conundrum - that of an omnipotent, all-loving deity magisterially presiding over a world in which widespread evil is so pervasive. And what a mind bender this is!

Milan, David An atheist and his christian friend are engaged in cordial conversation. The latter is taken aback and is rather indignant when his atheist friend declaims, 'On this question of the existence of god I believe that our respective positions are much closer than you imagine'. The Christian's firm riposte is that, by definition, such a harmony of viewpoints is impossible. Unfazed, his non-believing friend offers a thoughtful defence of his claim. He begins, 'You know that, since time (...) immemorial, humankind has taken unto itself all manner of gods, and that almost all of these tribal deities have long since vanished into obscurity.'.

We historically trace various non-conventional explanations for the origin of the cosmic microwave background and discuss their merit, while analyzing the dynamics of their rejection, as well as the relevant physical and methodological reasons for it. It turns out that there have been many such unorthodox interpretations; not only those developed in the context of theories rejecting the relativistic paradigm entirely but also those coming from the camp of original thinkers firmly entrenched in the relativistic milieu. In fact, the orthodox (...) interpretation has only incrementally won out against the alternatives over the course of the three decades of its multi-stage development. While on the whole, none of the alternatives to the hot Big Bang scenario is persuasive today, we discuss the epistemic ramifications of establishing orthodoxy and eliminating alternatives in science, an issue recently discussed by philosophers and historians of science for other areas of physics. Finally, we single out some plausible and possibly fruitful ideas offered by the alternatives. (shrink)

:There are manifold intriguing issues located within largely unexplored borderlands of bioethics, future studies, and astrobiology. Human enhancement has for quite some time been among the foci of bioethical debates, but the same cannot be said about its global, transgenerational, and even cosmological consequences. In recent years, discussions of posthuman and, in general terms, postbiological civilization have slowly gained a measure of academic respect, in parallel with the renewed interest in the entire field of future studies and the great strides (...) made in understanding of the origin and evolution of life and intelligence in their widest, cosmic context. These developments promise much deeper synergic answers to questions regarding the long-term future of enhancement: how far can it go? Is human enhancement a further step toward building a true postbiological civilization? Should we actively participate and help shape this process? Is the future of humanity “typical” in the same Copernican sense as our location in space and time is typical in the galaxy, and if so, can we derive important insights about the evolutionary pathways of postbiological evolution from astrobiological and Search for ExtraTerrestrial Intelligence studies? These and similar questions could be understood as parts of a possible unifying research program attempting to connect cultural and moral evolution with what we know and understand about their cosmological and biological counterparts.

We describe a significant practical consequence of taking anthropic biases into account in deriving predictions for rare stochastic catastrophic events. The risks associated with catastrophes such as asteroidal/cometary impacts, supervolcanic episodes, and explosions of supernovae/gamma-ray bursts are based on their observed frequencies. As a result, the frequencies of catastrophes that destroy or are otherwise incompatible with the existence of observers are systematically underestimated. We describe the consequences of the anthropic bias for estimation of catastrophic risks, and suggest some directions for (...) future work. (shrink)

Dwork, Hardt, Pitassi, Reingold, & Zemel [6] introduced two notions of fairness, each of which is meant to formalize the notion of similar treatment for similarly qualified individuals. The first of these notions, which we call additive metric fairness, has received much attention in subsequent work studying the fairness of a system composed of classifiers which are fair when considered in isolation [3, 4, 7, 8, 12] and in work studying the relationship between fair treatment of individuals and fair treatment (...) of groups [6, 7, 13]. Here, we extend these lines of research to the second, less-studied notion, which we call multiplicative metric fairness. In particular, we exactly characterize the fairness of conjunctions and disjunctions of multiplicative metric fair classifiers, and the extent to which a classifier which satisfies multiplicative metric fairness also treats groups fairly. This characterization reveals that whereas additive metric fairness becomes easier to satisfy when probabilities of acceptance are small, leading to unfairness under functional and group compositions, multiplicative metric fairness is better-behaved, due to its scale-invariance.

The well-known argument against the Search for ExtraTerrestrial Intelligence (SETI) due to George Gaylord Simpson is re-analyzed almost half a century later, in the light of our improved understanding of preconditions for the emergence of life and intelligence brought about by the ongoing “astrobiological revolution”. Simpson’s argument has been enormously influential, in particular in biological circles, and it arguably fueled the most serious opposition to SETI programmes and their funding. I argue that both proponents and opponents of Simpson’s argument have (...) occasionally mispresented its core content. Proponents often oversimplify it as just another consequence of biological contingency, thus leaving their position open to general arguments limiting the scope of contingency in evolution (such as the recent argument of Geerat Vermeij based on selection effects in the fossil record). They also tend to neglect that the argument has been presented as essentially atemporal, while referring to entities and processes that are likely to change over time; this has become even less justifiable as our astrobiological knowledge increased in recent years. Opponents have failed to see that the weaknesses in Simpson’s position could be removed by restructuring of the argument; I suggest one way of such restructuring, envisioned long ago in the fictional context by Stanislaw Lem. While no firm consensus has emerged on the validity of Simpson’s argument so far, I suggest that, contrary to the original motivation, today it is less an anti-SETI argument, and more an astrobiological research programme. In this research programme, SETI could be generalized into a platform for testing some of the deepest assumptions about evolutionary continuity and the relative role of contingency versus convergence on unprecedented spatial and temporal scales.

The seminal Satisfiability Coding Lemma of Paturi, Pudlák, and Zane is a coding scheme for satisfying assignments of k-CNF formulas. We generalize it to give a coding scheme for implicants and use this generalized scheme to establish new structural and algorithmic properties of prime implicants of k-CNF formulas. Our first application is a near-optimal bound of n⋅ 3^{n(1-Ω(1/k))} on the number of prime implicants of any n-variable k-CNF formula. This resolves an open problem from the Ph.D. thesis of Talebanfard, who (...) proved such a bound for the special case of constant-read k-CNF formulas. Our proof is algorithmic in nature, yielding an algorithm for computing the set of all prime implicants - the Blake Canonical Form - of a given k-CNF formula. The problem of computing the Blake Canonical Form of a given function is a classic one, dating back to Quine, and our work gives the first non-trivial algorithm for k-CNF formulas. (shrink)

This paper interprets and analyzes the debate having taken place in 1995 between E. Gellner and A. Smith concerning the problem of the emergence of nations. This discussion is used as an example to show the basic general features of two approaches in theories of nationalism - the modernist and the ethno symbolic ones. Pointing to the common assumptions shared by Gellner's and Smith's theories of nations, the author interprets ethno-symbolism as a sort of internal self-criticism of the modernist standpoint. (...) This polemic is therefore interpreted not as a debate between "creationist" and "evolutionist" solutions to the problem of the emergence of nations, but rather as a debate between two theoretical paradigms defining different research priorities in studying nations and nationalisms. From this perspective, the author concludes that the ethno symbolic approach to the genealogy of nations has broader heuristic capacities than the modernist paradigm, at least when the emergence of "peripheral nations" and the understanding of the dynamic of their nationalisms are concerned. U radu je interpretiran i analiziran spor koji su vodili E. Gelner i A. Smit 1995. godine o problemu nastanka nacija. Na primenu ove diskusije prikazane su osnovne opste karakteristike dva pristupa u teorijama nacionalizma modernistickog i etnosimbolickog. Ukazujuci na zajednicke pretpostavke Gelnerove i Smitove teorije nacija, autor je etnosimbolizam tumacio kao jednu vrstu unutrasnje samokritike modernistickog stanovista. Na taj nacin, ova polemika nije interpretirana kao spor izmedju "kreacionistickog" i "evolucionistickog" resenja problema nastanka nacija, vec prevashodno kao spor dve teorijske paradigme koje razlicito odredjuju istrazivacke prioritete u tematizaciji nacija i nacionalizama. Sa tog stanovista, autor je zakljucio da etnosimbolicki pristup genealogiji nacija ima vece heuristicke kapacitete od modernisticke paradigme, bar kada je u pitanju problem nastanka "perifernih nacija " i razumevanja dinamike njihovih nacionalizama.

The aim of the paper is to improve availability classifications of components for application in construction systems. Construction production systems belong to project-based systems with serial-parallel structures with or without redundant components, and the availability function has a significant impact on the performance indicators of components and systems. The main indicators of function of the components are the availability, capacity, costs, and project time. A new approach to classification makes it possible to choose the most appropriate methodology for assessing component (...) availability in the bidding phase, and managing company’s machine park. The new classification approach was tested on a practical example. The results obtained confirmed the justification for extending the classical approach to the classification of the availability of components. (shrink)

It has already become a commonplace to discuss postbiological evolution in various contexts of futures studies, bioethics, cognitive sciences, philosophical anthropology, or even economics and SETI studies. The assumption is that technological/cultural evolution will soon entirely substitute for the biological processes which underlie human existence – and, by analogy, the existence of other independently evolved intelligent beings, if any. Various modes of postbiological evolution of humans have been envisioned in both fictional and discursive contexts. Little thought has been devoted so (...) far to the question whether these postbiological modes are truly final in both logical and conceptual terms. What lies beyond the postbiological realm? Clearly, only a few radical speculations on the topic can be offered. In this paper, it is argued that in a sufficiently broad subset of scenarios for postbiological evolution there will be a kind of reverse trend: the one of reintegration with the biological universe, by that point understood in a much wider and more inclusive sense. The argument for such reintegration could be understood through the metaphor of expanding Klein bottle as a symbolic image of the post-postbiological evolutionary trajectories. This kind of trajectory will lead to the state in which products of culture are indistinguishable from the natural environment, suggesting practical consequences for our SETI efforts. (shrink)

The paper reconsiders the Weber Thesis of a linkage between Calvinism and capitalism. It first restates this sociological Thesis in terms of the Calvinist doctrine of predestination as its theological core and premise in virtue of being treated as the crucial religious factor of the spirit of modern capitalism. Consequently, it proposes that the Weber Thesis’ validity and consistency depends on that doctrine, succeeding or failing as a sociological theory with the latter depending on whether or not it is unique (...) in theological terms, as well as economic-social consequences. For that purpose, it reexamines and compares the Calvinist doctrine of predestination with the pre-Calvinist versions and infers that it is basically identical to or compatible with these. It then draws the implications for the Weber Thesis in respect of the degree of its validity or consistence. It concludes that the Weber Thesis likely is fail as a sociological-economic theory with the Calvinist doctrine of predestination to the extent that the latter is its theological ground and revealed not to be unique and new theologically and probably in terms of its societal effects.

In this paper, I explore ways in which metaphors contribute to hermeneutical resistance, that is, to practices that overcome and/or ameliorate hermeneutical injustice. I distinguish two aspects of hermeneutical injustice and two corresponding kinds of resistance: exoteric and esoteric hermeneutical injustice/resistance. The former injustice consists in unjust harm due to an inability to make one's experience understood to others. The latter consists in such a harm due to an inability to fully understand one's own experiences. In exoteric hermeneutical resistance, metaphors (...) can overcome resistances in others to understand oppressed agents' contributions because of its automatic processing and anti-deniability. In esoteric hermeneutical resistance, metaphors may highlight common structures in various aspects of marginalised agent's experiences, they can provide means of denoting social properties obscured by hermeneutical injustice and they can exhibit hermeneutical injustice by resisting interpretation. I illustrate these practices through works by Emily Dickinson, Ralph Ellison, Frantz Fanon, Paul Celan and Nelly Sachs. Those examples show the power of metaphors in hermeneutical resistance.

Both “optimists” and “sceptics” in regard to extraterrestrial intelligence tend to hold the view that we are entitled to an epistemically clear position: either there will be a signal, in the sufficiently general sense, proving the existence of extraterrestrial intelligence, or no such signal is forthcoming. The distinction, I wish to argue here, is not at all so clear-cut. On the contrary, there are arguments, intrinsic to the subject matter, to the effect that the detection of ETI will be a (...) protracted affair characterized by uncertainty at every step. Such view of SETI discovery mandates different policies from those conventionally discussed in the literature. We should not gear our expectations and publicly promote the view that the Contact will be a clear-cut, Archimedean “Eureka!”-style discovery. In contrast, the tempo and mode of the process of discovery might significantly influence societal and political reactions to the discovery. We should be prepared for such a protracted unfolding of events. (shrink)

The paper addresses the ‘rational choice only’ reconstruction, characterization, and interpretation of classical and neoclassical economics. It argues that such a reconstruction is inaccurate failing to do justice to the dual theoretical character of classical/neoclassical economics. The paper instead proposes and shows that the latter involves not only elements of ‘rational choice theory’ but also those of an alternative conception. It identifies various and important ideas, observations, and implications of irrational choice and action within classical/neoclassical economics. One class of such (...) ingredients involves forms, expressions, and cases—i.e. specification and classification—of irrational choices in the economy. Another class comprises the social and other factors—i.e. economic sociology or social economics—of irrational choices in the economy. The paper’s intended contribution is to help identify and clarify the extant sources and alternatives of rational choice theory in conventional economics.... (shrink)

A modern assessment of the classical Boltzmann-Schuetz argument for large-scale entropy fluctuations as the origin of our observable cosmological domain is given.The emphasis is put on the central implication of this picture which flatly contradicts the weak anthropic principle as an epistemological statement about the universe. Therefore, to associate this picture with the anthropic principle as it is usually done is unwarranted. In particular, Feynman's criticism of theanthropic principle based on the entropy-fluctuation picture is a product of this semantic confusion.

The advent of artificial intelligence (AI) systems has provoked a lot of discussions in both epistemological, bioethical and risk-analytic terms, much of it rather paranoid in nature. Unless one takes an extreme anthropocentric and chronocentric stance, this process can be safely regarded as part and parcel of the sciences of the origin. In this contribution, I would like to suggest that at least four different classes of arguments could be brought forth against the proposition that AI - either human-level or (...) superintelligent - represents in itself a credible existential threat to humanity in either nearby or distant future. Part of the same argumentation is applicable to the general notion of postbiological evolution, which has caused even more unnecessary confusion and uproar in both laymen and philosophical circles. While the due attention should be given to the risks and dangers of the transitional period, there are many reasons why we should openly support and cheer for humanity's transition into the postbiological epoch.

Anthropic reasoning has lately been strongly associated with the string theory landscape and some theories of particle cosmology, such as cosmological inflation. The association is not, contrary to multiple statements by physicists and philosophers alike, necessary. On the contrary, there are clear reasons and instances in which the anthropic reasoning is useful in a diverse range of fields such as planetary sciences, geophysics, future studies, risk analysis, origin of life studies, evolutionary theory, astrobiology and SETI studies, ecology, or even strategic (...) studies and global policy. The association of anthropic reasoning with string theory and particle cosmology has not only become the standard wisdom, but has been often construed in a negative way, in order to demonstrate or insinuate that such reasoning is too abstract or even belongs to 'fringe science', remote from run-of-the-mill research practices in any other more 'mundane' and less theoretical scientific discipline. The purpose of this paper is to (i) analyse some of the counter-examples to the standard wisdom, (ii) suggest that the anthropic reasoning is more flexible, more general, and less fashion-driven than the detractors state. In addition, we consider some historical and/or extrascientific motivation for this persistent prejudice. (shrink)

We investigate intuitionistic propositional modal logics in which a modal operator is equivalent to intuitionistic double negation. Whereas ¬¬ is divisible into two negations, is a single indivisible operator. We shall first consider an axiomatization of the Heyting propositional calculus H, with the connectives →,∧,∨ and ¬, extended with . This system will be called Hdn . Next, we shall consider an axiomatization of the fragment of H without ¬ extended with . This system will be called Hdn + . (...) We shall show that these systems are sound and complete with respect to specific classes of Kripke-style models with two accessibility relations, one intuitionistic and the other modal. This type of models is investigated in [2] and [3], and here we try to apply the techniques of these papers to an intuitionistic modal operator with a natural interpretation. The full results of our investigation will be published in [4] and [1]. (shrink)

The connectivity patterns of many neural circuits are highly ordered and often impressively complex. The intricate order and complexity of neuronal wiring remain not only a challenge for questions related to circuit functions but also for our understanding of how they develop with such an apparent precision. The chemotropic guidance of the growing axon by target‐derived cues represents a central paradigm for how neurons get connected with the correct target cells. However, many studies reveal a remarkable variety of important target‐independent (...) wiring mechanisms. These mechanisms include axonal sorting, axonal tiling, growth cone polarization, as well as cell‐intrinsic mechanisms underlying growth cone sprouting, and neurite branching. Our review focuses on target independent wiring mechanisms and in particular on recent progress emerging from studies on three different sensory systems: olfactory, visual, and somatosensory. We discuss molecular mechanisms that operate during axon‐axon interactions or constitute axon‐intrinsic functions and outline how they complement the well‐known target‐dependent wiring mechanisms.

In the first part of this essay, the author discusses certain aspects of the Hindu and Buddhist philosophical and religious conceptions that could have made some impact on the European ethics before Schopenhauer. In the second part, he deals with various channels of possible Buddhist influence on Schopenhauer's ethical thought. Finally, in discussing Buddhist-Wittgenstein relationship, one is confronted with convergent, yet independent, responses to similar sets of problems. Independently, and less systematically than Buddhist philosophical schools, Wittgenstein indicates the way of (...) liberation that cures from the "metaphysical pain " emerging from inappropriate use of language. His own project, however, was not metaphysical, but meta-linguistic in a very specific sense. The philosophical "cure" from the language disease leads ultimately to the "purification " and "decontamination " of thought: in turn, the mind rests in peace and silence before the senseless, paradoxical questions of the moral, esthetical religious or metaphysical character. Ovaj esej se sastoji iz tri dela. U prvom delu autor razmatra izvesne aspekte hinduistickih i budistickih filozofskih i religijskih doktrina koje su mogle imati uticaja na evropsku etiku do Sopenhauera. Na primer, Pironov metod uzdrzavanja od suda ispoljava zapanjujucu slicnost s izvornim budistickim metodom meditacije. U evropskoj filozofiji slican metod je razvijen u Huserlovoj fenomenologiji, iako na jedan puno slozeniji teorijski nacin. Razmatranje postklasicnih, helenistickih moralnih doktrina vodi od problema izvora do nekih specificnih pitanja komparativne ili hermeneuticke prirode. Pa ipak, u povesti zapadne filozofije nije se jasno ukazalo na dug budistickoj etici sve dok Sopenhauer nije napisao Svet kao volja i predstava. U drugom delu rada autor se stoga bavi razlicitim tokovima moguceg budistickog uticaja na Sopenhauerovu eticku misao. Vrlo cesto Sopenhauerovi kljucni argumenti su pozajmljeni iz indijskih soterioloskih ucenja. S druge strane, on je u stanju da prilagodi ta orijentalna ucenja svojim vlastitim pojmovima i idejama. Izmedju njegove filozofije i indijskih filozofija moguce je uspostaviti odnos konvergentnosti. Iz toga je proizislo jedinstveno stapanje dveju perspektiva koje se ponekad oznacava i kao "evropski budizam". Za razliku od Sopenhauera Vitgenstajn ne upucuje ni na kakvo delo, ili odlomak iz hinduisticke ili budisticke literature. Stavise, tesko je braniti stav da je Sopenhauer imao ikakvu znacajniju posrednicku ulogu u budjenju Vitgenstajnovog interesovanja za budizam. Mnogo je, u stvari, lakse ukazati na vaznost Sopenhauerovog uticaja na "etickog" Vitgenstajna iz Tractatusa, nego utvrditi ikakvu slicnost izmedju sopenhauerovsko-budisticke i Vitgenstajnove eticke koncepcije. Raspravljajuci o odnosu izmedju Vitgenstajna i budizma, susrecemo se s konvergentnim, ali nezavisnim odgovorima na slicne vrste problema. Nezavisno, i manje sistematicno od budistickih filozofskih skola, Vitgenstajn ukazuje na put oslobodjenja sto leci od "metafizicke boli" zasnovane na nepravilnoj upotrebi jezika. Medjutim, njegov vlastiti projekat nije bio metafizicki, vec metalingvisticki u jednom vrlo specificnom smislu. Filozofsko "izlecenje" od bolesti jezika vodi, u krajnjoj liniji, do "ociscenja" i "dekontaminacije" misli. Kao rezultat toga, um nalazi spokoj i mir pred besmislenim, paradoksalnim pitanjima moralnog, estetickog religijskog ili metafizickog karaktera. (shrink)

Hannah Arendt is famous for her influential and innovative analysis of totalitarianism. However, her thinking on political systems and ideologies is far from limited to this theorization. Arendt also criti-cizes modern liberalism and its ideological framework. Indeed, Arendt’s thought reveals many of the political consequences of world-lessness, the loss of the world in contemporary times, particularly in terms of a sense of disempowerment and the advent of a technical vision of politics. This article looks at the political effects of world-lessness, (...) exploring the emerging opposition between liberal post-politics and conservative hyper-politics. This critique of Arendt’s thought can help us better understand the issues and questions raised by liberalism. (shrink)
