Dowód twierdzenia Bella sprowadza się do wyprowadzenia którejś z nierówności Bella. W ich standardowych wyprowadzeniach jednak kluczową rolę odgrywa warunek faktoryzowalności łącznego prawdopodobieństwa warunkowego, który można uzyskać jako konsekwencję dwóch innych warunków, znanych jako parameter independence i outcome independence. Pierwszy z nich jest dość oczywistym wyrazem warunku lokalności, natomiast drugi budzi wątpliwości. Ponieważ jednak jest on uszczegółowieniem warunku screening off zasady wspólnej przyczyny, jego podważenie wymagałoby zakwestionowania również tego warunku. Gdyby się to powiodło, efektywny dowód twierdzenia Bella wymagałby wyprowadzenia nierówności (...) Bella nie wykorzystującego żadnego uszczegółowienia warunku screening off. Przestawiona zostanie sugestia kierunku, w jakim powinny iść poszukiwania modelu naruszającego ten warunek. (shrink)

Putnam’s proof that time flow is incompatible with Relativity is underestimated, mostly due to Stein’s interpretation of the notion of reality in it as a two-term relation. This interpretation makes it vulnerable to easy criticism and makes various ways of escaping its conclusion possible. An alternative approach is proposed, resulting in a formalization which seems closer to Putnam’s intentions where reality is interpreted as a non-relational property. Although it makes the proof immune to all standard strategies of blocking the proof, (...) it reveals its real weak point which consists in assuming an overly strong interpretation of the principle of relativity.

This paper is a reply to Jan Wolenski's polemics (Filozofia Nauki 1/2000) against the author's essay „On the Epistemic Impotence of Analytical Philosophy” (Filozofia Nauki 3-4/1998). The author expresses his conviction that it is in analytical philosophy that the most interesting - and at the same time well-established - cognitive results have been reached, but many of these results have been obtained, not thanks to the declared semantic method, but thanks to the phenomenological method, which have been used at least (...) unconsciously. Therefore the gap between phenomenology and analytical philosophy is not so huge as it might seem at first glance. (shrink)

Artykuł dotyczy zagadnienia charakteru przedmiotów matematyki. Autor stara się określić ich charakter w perspektywie definicji naoczności (którą przyjmuje od Kanta). Podstawową kwestią jest tu zagadnienie: w jaki sposób przedmioty te przedstawiają się ludzkiemu umysłowi.

The quantum-relativistic breakthrough in physics has radically changed the scientific worldview. Several basic intuitions, which underlie traditional philosophy of nature, has been abandoned. As a result of this fact, scientists started to pronounce themselves as the highest authority in the philosophy of nature, leaving for the philosophers only the role of commentators. However, it is not physical theories, but their certain interpretations, or disinterpretations, which contradict common intuitions. In the case of relativistic theory, there is an alternative interpretation which allows (...) us to reconcile its content with pre-relativistic intuitions. Therefore it suggest that we should be critical also to other alleged consequences of the „new physics”. (shrink)

This is a defence of some kind of reality of relativistic effects, against the thesis that they are mere kinematic appearances or deceptions.

The observation that the standard solution of the paradox of the Liar is not satisfactory as a pragmatic solution of a semantic problem restores its former status as a semantic antinomy. Since the antinomy originates from Tarski's T scheme, a conservative modification of the standard semantics is looked for, which would prevent applying the scheme T to anomalous statements. Two such modifications are considered. The first is simpler and implies Kleene's weak tables for three-valued logic. The second, more complex but (...) also more intuitive, agrees with Kleene's strong tables. This undermines the seemingly natural intuition that a sentence and the sentence attributing truth to it have the same truth conditions, which is compatible only with the weak tables. (shrink)

The author proposes a formalization of Hilary Putnam's proof of the thesis that time does not pass. This enables one to eliminate difficulties connected with the original formulation.

The paper is a reply to Jan Czerniawski's paper „On epistemic impotence of analytical philosophy” (Filozofia Nauki 3-4/1998). Czerniawski argues that the analytic method consists either in arbitrary stipulations or in the appeal to linguistic intuitions. He claims that the latter are subjective and moreover they cannot help deciding objective problems, while the former are an arbitrary creation of truth. Hence, the analytic method has to be assisted by an intuitive insight into objective situations. However, Czerniawski forgets (...) one quite elementary circumstance. For there is something else between linguistic intuitions and arbitrary terminological stipulations - namely precisation of intuitions. And this is what the analytic philosophers care for the most; those analytic philosophers who are logicians at the same time, in particular. According to the analytic philosophers philosophically relevant intuitive insight into objective situations is always achieved through language. Therefore, we do not need an epistemic viagra in the form of the extra-linguistic insight directly into the objective situation. (shrink)

W artykule streszczam tzw. Debatę Dummett Lash, która miała miejsce na łamach czasopisma angielskich dominikanów New Blackfriars w latach 1987-1989. Rozróżniam trzy główne nurty debaty. W pierwszym głównym oponentem filozofa Michaela Dummetta, inicjatora debaty, był benedyktyn Bede Griffith, który proponował symboliczne rozumienie Biblii. Według Dummetta jednak rozumienie symboliczne opiera się na wcześniejszym rozumieniu dosłownym, które z tego powodu nie może być odrzucone. W drugim Dummett argumentował za potrzebą intersubiektywnego uzasadnienia naszej przynależności do konkretnego Kościoła, ponieważ w innym przypadku nie bylibyśmy (...) w stanie podać żadnych racji na rzecz zmiany poglądów przez tych, którzy nie wyznają chrześcijaństwa. Jego główna teza nie była atakowana, niektórzy uczestnicy debaty kwestionowali jednak niektóre szczegóły natury tego uzasadnienia i całego paradygmatu myślenia w kategoriach wyznaniowych. Trzeci i kluczowy nurt debaty miał swoje źródło w nacisku Dummetta na to, że współczesna katolicka biblistyka odeszła od tradycyjnego katolickiego nauczania i stąd konieczne jest ogłoszenie granic możliwej interpretacji katolickich artykułów wiary. Wielu teologów, którzy brali udział w debacie, postrzegało to żądanie Dummetta jako zagrożenie dla naukowej wolności, a najważniejszy z nich, Nicholas Lash, profesor University of Cambridge, wskazywał, że także postulowane przez Dummetta ogłoszenie będzie wymagało interpretacji, stąd wyznaczenie granic możliwej interpretacji jest po prostu niemożliwe. Na końcu artykułu dochodzę do wniosku, że możemy postrzegać Dummetta zarówno jako filozofa, który stara się traktować religię w sposób racjonalny, jak i prostego katolickiego świeckiego, chcącego mieć bezpośredni dostęp do Objawienia bez pośrednictwa ekspertów od biblistyki.

This paper clarifies Merleau-Ponty’s original account of “higher-order” cognition as fundamentally embodied and enacted. Merleau-Ponty’s philosophy inspired theories that deemphasize overlaps between conceptual knowledge and motor intentionality or, on the contrary, focus exclusively on abstract thought. In contrast, this paper explores the link between Merleau-Ponty’s account of motor intentionality and his interpretations of our capacity to understand and interact productively with cultural symbolic systems. I develop my interpretation based on Merleau-Ponty’s analysis of two neuropathological modifications of motor intentionality, the case (...) of the brain-injured war veteran Schneider, and a neurological disorder known as Gerstmann’s syndrome. Building on my analysis of Schneider’s sensorimotor compensatory performances in relation to his limitations in the domains of algebra, geometry, and language usage, I demonstrate a strong continuity between the sense of embodiment and enaction at all these levels. Based on Merleau-Ponty’s interpretations, I argue that “higher-order” cognition is impaired in Schneider insofar as his injury limits his sensorimotor capacity to dynamically produce comparatively more complex differentiations of any given phenomenal structure. I then show how Merleau-Ponty develops and specifies his interpretation of Schneider’s intellectual difficulties in relation to the ambiguous role of the body, and in particular the hand, in Gerstmann’s syndrome. I explain how Merleau-Ponty defends the idea that sensorimotor and quasi-representational cognition are mutually irreducible, while maintaining that symbol-based cognition is a fundamentally enactive and embodied process.

Marx’s vision of unalienated production is often thought to be subject to decisive objections. This article argues that these objections rely on a misinterpretation of Marx’s position. It provides a new interpretation of Marx’s vision of unalienated production. Unlike another well-known account, it suggests that unalienated production involves realizing oneself through providing others with the goods and services they need for their self-realization. It argues that this view is appealing and that it offers a more successful response to objections than (...) previous interpretations. In doing so, it hopes to put Marx’s concern with alienation and nonalienation back on the table. (shrink)

Conceiving of nuclear energy as a social experiment gives rise to the question of what to do when the experiment is no longer responsible or desirable. To be able to appropriately respond to such a situation, the nuclear energy technology in question should be reversible, i.e. it must be possible to stop its further development and implementation in society, and it must be possible to undo its undesirable consequences. This paper explores these two conditions by applying them to geological disposal (...) of high-level radioactive waste. Despite the fact that considerations of reversibility and retrievability have received increased attention in GD, the analysis in this paper concludes that GD cannot be considered reversible. Firstly, it would be difficult to stop its further development and implementation, since its historical development has led to a point where GD is significantly locked-in. Secondly, the strategy it employs for undoing undesirable consequences is less-than-ideal: it relies on containment of severely radiotoxic waste rather than attempting to eliminate this waste or its radioactivity. And while it may currently be technologically impossible to turn high-level waste into benign substances, GD’s containment strategy makes it difficult to eliminate this waste’s radioactivity when the possibility would arise. In all, GD should be critically reconsidered if the inclusion of reversibility considerations in radioactive waste management has indeed become as important as is sometimes claimed. (shrink)

This paper addresses theoretical challenges, still relevant today, that arose in the first decades of the twentieth century related to the concept of the organism. During this period, new insights into the plasticity and robustness of organisms as well as their complex interactions fueled calls, especially in the UK and in the German-speaking world, for grounding biological theory on the concept of the organism. This new organism-centered biology understood organisms as the most important explanatory and methodological unit in biological investigations. (...) At least three theoretical strands can be distinguished in this movement: Organicism, dialectical materialism, and holistic biology. This paper shows that a major challenge of OCB was to describe the individual organism as a causally autonomous and discrete unit with consistent boundaries and, at the same time, as inextricably interwoven with its environment. In other words, OCB had to conciliate individualistic with anti-individualistic perspectives. This challenge was addressed by developing a concept of life that included functionalist and metabolic elements, as well as biochemical and physical ones. It allowed for specifying organisms as life forms that actively delimit themselves from the environment. Finally, this paper shows that the recent return to the concept of the organism, especially in the so-called “Extended Evolutionary Synthesis,” is challenged by similar anti-individualistic tendencies. However, in contrast to its early-twentieth-century forerunner, today’s organism-centered approaches have not yet offered a solution to this problem. (shrink)

This paper provides an analysis of the intrinsic/extrinsic distinction, as applied both to properties and to relations. In contrast to other accounts, the approach taken here locates the source of a property’s intrinsicality or extrinsicality in the manner in which that property is ‘logically constituted’, and thus – plausibly – in its nature or essence, rather than in e.g. its modal profile. Another respect in which the present proposal differs from many extant analyses lies in the fact that it does (...) not seek to analyse the ‘global’ distinction between intrinsic and extrinsic properties on the basis of the ‘local’ distinction between having a property intrinsically and having it extrinsically. Instead, the latter distinction is explicated on the basis of the former. (shrink)

In recent years, biologists and philosophers of science have argued that evolutionary theory should incorporate more seriously the idea of ‘reciprocal causation.’ This notion refers to feedback loops whereby organisms change their experiences of the environment or alter the physical properties of their surroundings. In these loops, in particular niche constructing activities are central, since they may alter selection pressures acting on organisms, and thus affect their evolutionary trajectories. This paper discusses long-standing problems that emerge when studying such reciprocal causal (...) processes between organisms and environments. By comparing past approaches to reciprocal causation from the early twentieth century with contemporary ones in niche construction theory, we identify two central reoccurring problems: All of these approaches have not been able to provide a conceptual framework that allows maintaining meaningful boundaries between organisms and environments, instead of merging the two, and integrating experiential and physical kinds of reciprocal causation. By building on case studies of niche construction research, we provide a model that is able to solve these two problems. It allows distinguishing between mutually interacting organisms and environments in complex scenarios, as well as integrating various forms of experiential and physical niche construction. (shrink)

Insight problem solving is thought to underpin creative thought as it incorporates both divergent (generating multiple ideas and solutions) and convergent (arriving at the optimal solution) thinking approaches. The current literature on schizotypy and creativity is mixed and requires clarification. An alternate approach was employed by designing an exploratory web-based study using only correlates of schizotypal traits (paranoia, dissociation, cognitive failures, fantasy proneness, and unusual sleep experiences) and examining which (if any) predicted optimal performance on an insight problem-solving task. One (...) hundred and twenty-one participants were recruited online from the general population and completed the number reduction task. The discovery of the hidden rule (HR) was used as a measure of insight. Multivariate logistic regression analyses highlighted persecutory ideation to best predict the discovery of the HR (OR = 1.05; 95% CI 1.01–1.10, p = 0.017), with a one-point increase in persecutory ideas corresponding to the participant being 5% more likely to discover the HR. This result suggests that persecutory ideation, above other schizotypy correlates, may be involved in insight problem solving. (shrink)

Should Marxists support universal basic income (UBI), i.e., a regular cash income paid to all without a means test or work requirement? This paper considers one important argument that they should, namely that UBI would be instrumentally effective in helping to bring about communism. It argues that previous answers to this question have paid insufficient attention to a logically prior question: what is Marx’s account of communism? In reply, it distinguishes two different accounts: a left-libertarian version that associates communism with (...) the freedom to live and work how one wants, and a perfectionist version that associates communism with the overcoming of alienated labour and self-realisation in work. It argues that UBI would make steps towards the left-libertarian account but not the perfectionist account. Ultimately, then, the question “should Marxists support basic income?” is shown to partly depend on which account of communism Marxists want to bring about. (shrink)
