A classic result in the foundations of Yang-Mills theory, due to J. W. Barrett ["Holonomy and Path Structures in General Relativity and Yang-Mills Theory." Int. J. Th. Phys. 30, ], establishes that given a "generalized" holonomy map from the space of piece-wise smooth, closed curves based at some point of a manifold to a Lie group, there exists a principal bundle with that group as structure group and a principal connection on that bundle such that the holonomy map corresponds to (...) the holonomies of that connection. Barrett also provided one sense in which this "recovery theorem" yields a unique bundle, up to isomorphism. Here we show that something stronger is true: with an appropriate definition of isomorphism between generalized holonomy maps, there is an equivalence of categories between the category whose objects are generalized holonomy maps on a smooth, connected manifold and whose arrows are holonomy isomorphisms, and the category whose objects are principal connections on principal bundles over a smooth, connected manifold. This result clarifies, and somewhat improves upon, the sense of "unique recovery" in Barrett's theorems; it also makes precise a sense in which there is no loss of structure involved in moving from a principal bundle formulation of Yang-Mills theory to a holonomy, or "loop", formulation.

We show that previous results from epistemic network models showing the benefits of decreased connectivity in epistemic networks are not robust across changes in parameter values. Our findings motivate discussion about whether and how such models can inform real-world epistemic communities. As we argue, only robust results from epistemic network models should be used to generate advice for the real-world, and, in particular, decreasing connectivity is a robustly poor recommendation.

In this paper, we examine the relationship between general relativity and the theory of Einstein algebras. We show that according to a formal criterion for theoretical equivalence recently proposed by Halvorson and Weatherall, the two are equivalent theories.

To make sense of large data sets, we often look for patterns in how data points are “shaped” in the space of possible measurement outcomes. The emerging field of topological data analysis offers a toolkit for formalizing the process of identifying such shapes. This article aims to discover why and how the resulting analysis should be understood as reflecting significant features of the systems that generated the data. I argue that a particular feature of TDA—its functoriality—is what enables TDA to (...) translate visual intuitions about structure in data into precise, computationally tractable descriptions of real-world systems.

Whether or not we call a love-like relationship with robots true love, some people may feel and claim that, for them, it is a sufficient substitute for love relationship. The love relationship between humans has a special place in our social life. On the grounds of both morality and law, our significant other can expect special treatment. It is understandable that, precisely because of this kind of relationship, we save our significant other instead of others or will not testify against (...) her/him. How as a society should we treat love-like relationships humans with robots? Based on the assumption that robots do not have an inner life and are not moral patients, I defend the thesis that this kind of relationship should be protected by criminal law. (shrink)

Praca zawiera pogłębioną analizę dwóch ważnych, powiązanych ze sobą doktryn – utylitaryzmu i liberalizmu. Ich powstanie i rozwój zbiega się z historią uprzemysłowionego świata Zachodu. XIX wiek to bez wątpienia okres pełnego rozkwitu liberalizmu w jego klasycznej postaci. John Stuart Mill (1806–1873) jest kluczową postacią w historii obydwu doktryn. Jego dialog z utylitaryzmem ma w tle współczesne dylematy i takież interpretacje.

Reactive oxygen species (ROS) are highly reactive molecules produced in cells. So far, they have mostly been connected to diseases and pathological conditions. More recent results revealed a somewhat unexpected role of ROS in control of developmental processes. In this review, we elaborate on ROS in development, focussing on their connection to epithelial tissue morphogenesis. After briefly summarising unique characteristics of epithelial cells, we present some characteristic features of ROS species, their production and targets, with a focus on proteins important (...) for epithelial development and function. Finally, we provide examples of regulation of epithelial morphogenesis by ROS, and also of developmental genes that regulate the overall redox status. We conclude by discussing future avenues of research that will further elucidate ROS regulation in epithelial development. (shrink)

This manuscript is intended as a technical supplement to Rosenstock and O'Connor. Calculations are presented for the expected return for strategic players of an iterated prisoner's dilemma which includes guilt-prone grim trigger players, who apologize when they accidentally defect, as well as fake apologizers who in fact act as defectors. See Rosenstock and O'Connor for a discussion of how the results presented here can be interpreted, using ESS analysis and exploring basins of attraction under the replicator dynamics, to help understand (...) the conditions under which guilt can evolve. I hope for this note to both make it easier for others to understand and build on those results, and to demonstrate how expected returns can be calculated for various strategies in various games.

At Protagoras 353de, Socrates gives three possible reasons for calling some pleasures `wrong'. Scholarly attention has focused on the second of these, according to which pleasures are `wrong' when they have negative consequences. This paper argues that the first reason (the pleasures are fleeting) corresponds to beliefs held by Democritus, among others; and that the third reason (the pleasant things “give pleasure in whatever way and for whatever reason“) is the view adopted by Socrates in the dialogue.

Using results from evolutionary game theory, we analyze the conditions under which guilt can provide individual fitness benefits to actors, and so evolve. In particular, we focus on the individual benefits of guilty apology. We find that guilty apology is more likely to evolve in cases where actors interact repeatedly over long periods of time, where the costs of apology are low or moderate, and where guilt is hard to fake.

The debate on alternative punishments appears to be stagnating. The impasse may be overcome if we consider humans from a different philosophical perspective. If we answer differently the question of who we are punishing, we open new possibilities regarding the question of how we punish. In particular, by applying the extended mind thesis we can arrive at interesting outcomes and reopen the debate on alternative punishments. According to this theory, external artifacts—such as smartphones—can be considered part of our minds. In (...) this article, I defend the thesis that restricting access to personal technologies that are a part of one's self should be considered a form of punishment. Thus, a human who is considered from an extended perspective can be punished in a new way. (shrink)

Robots are becoming more visible parts of our life, a situation which prompts questions about their place in our society. One group of issues that is widely discussed is connected with robots’ moral and legal status as well as their potential rights. The question of granting robots rights is polarizing. Some positions accept the possibility of granting them human rights whereas others reject the notion that robots can be considered potential rights holders. In this paper, I claim that robots will (...) never have all human rights, even if we accept that they are morally equal to humans. I focus on the role of embodiment in the content of the law. I claim that even relatively small differences in the ontologies of entities could lead to the need to create new sets of rights. I use the example of Neanderthals to illustrate that entities similar to us might have required different legal statuses. Then, I discuss the potential legal status of human-like robots. (shrink)

Profesor Ryszard Panasiuk przez ostatnich kilka dekad należał do grona wiodących polskich filozofów. Jego książki na temat Hegla, ruchu młodoheglowskiego czy Marksa należą do kanonu historiografii idei. Publikowany tutaj obszerny wywiad z Profesorem może stanowić wartościowe i oryginalne źródło do historii inteligencji i humanistyki w tzw. Polsce Ludowej. Profesor Panasiuk opowiada w nim o swojej karierze naukowej, jednocześnie kreśląc obraz przemian akademickiego środowiska filozoficznego w powojennej Polsce. Wiele uwagi poświęca również swojej relacji z Bronisławem Baczką i innymi wybitnym reprezentantami Warszawskiej (...) Szkoły Historii Idei. Ponadto Profesor analizuje proces narastania prądów dysydenckich wśród zwolenników marksizmu po Październiku ’56 i wyjaśnia ostateczny rozkład post-stalinowskiej ortodoksji w polskim życiu intelektualnym tego okresu. Jak również dowodzi, że choć Marks stanowi ważny i wciąż warty badania rozdział w historii filozofii europejskiej, to marksizm, z uwagi na zawarty w nim koncept „radykalnej wspólnoty”, jest ideologią z gruntu utopijną.

The paper examines the theoretical merit of “semantic molecules” in Natural Semantic Metalanguage (NSM). Although semantic molecules are said to trace semantic dependence and necessity, compress complexity, and to account for what I call its productivity, that doesn't appear to be the case. This can be illustrated on the basis of a comparison of two explications for the same complex meaning—one containing a molecule and the other its decomposed elements. Counterfactual considerations suggest that the latter is not semantically dependent on (...) the lexicalized molecule and that it is, in turn, not necessary. The other side of the comparison cements the point. This leaves the issue of compression, complexity, and productivity—none of which are helped by semantic molecules, as they appear to do little more than conceal complexity. Meanwhile, they are not required to account for productivity. It seems that molecules may need to be rethought. (shrink)

Sharing on social media has become a daily routine for millions of users worldwide. Sharing transforms the experience of international migration as it enables migrants to maintain social relations and adapt to a new socioeconomic environment. But what does the term “sharing” mean for migrants active on Facebook? What are the contemporary meanings of sharing encouraged by Facebook’s affordances? This paper explores individual sharing strategies on Facebook among Polish migrants in Germany and the UK. On the basis of the material (...) collected through in-depth interviews (N=17) with Poles who have settled in Germany and the UK, it is proposed that the contemporary meaning of sharing has five dimensions: commercial, altruistic, social, connective and addictive. Different compositions of these dimensions can be found in most sharing practices on social media. Following a critique of commercial sharing on social media, it is further established that selling and other profit-driven activities are rather well recognized by the interviewees. However, some of them engage in commercial sharing with no direct selling intention. The article emphasizes that sharing practices help Polish migrants adapt to their bicultural reality in Germany and the UK. (shrink)

The present study is the first to measure event-related potentials associated with the processing of the emotional Stroop task (EST) with the use of an orthogonal factorial manipulation for emotional valence, arousal, and subjective significance (the importance of the current experience for goals and plans for the future). The current study aimed to investigate concurrently the role of the three dimensions describing the emotion-laden words for interference control measured in the classical version of the EST paradigm. The results showed that (...) reaction times were affected by the emotional valence of presented words and the interactive effect of valence and arousal. The expected emotional arousal effect was only found in behavioral results for neutrally valenced words. Electrophysiological results showed valence and subjective significance correlated with the amplitude differences in the P2 component. Moreover, the amplitude of the N450 component varied with the level of subjective significance. This study also demonstrated that exploratory event-related potential analysis provides additional information beyond the classical component-based analysis. The obtained results show that cognitive control effects in the EST may be altered by manipulation in the subjective significance dimension. (shrink)

Artykuł ten stanowi omówienie koncepcji szczęścia, którą można wywieść z pism św. Augustyna z Hippony. Autor podejmuje się systematycznej rekonstrukcji poglądów tego myśliciela, argumentując na rzecz tego, iż dokonanie jej jest możliwe, i twierdząc, iż pewne podstawowe wątki w jego myśli pozostały takie same w ciągu całej jego działalności intelektualnej. Są nimi przede wszystkim: twierdzenie, iż dążenie człowieka do osiągnięcia szczęścia jest dla niego naturalne; twierdzenie, że istotą szczęścia jest osiągnięcie Boga; oraz twierdzenie, że droga do owego szczęścia wiedzie przez (...) zyskiwanie przez człowieka mądrości. Autor przedstawia również główną zmianę w Augustyńskiej wizji szczęścia, którą stanowi „przeniesienie” możliwości jego osiągnięcia z życia obecnego na przyszłe. (shrink)

Tekst stanowi tłumaczenie traktatu Tomasza z Akwinu pt. De principiis naturae (O zasadach natury), stanowiącego opis podstawowych zagadnień filozofii przyrody i metafizyki w ujęciu Akwinaty. Są to przede wszystkim zagadnienia związane z powstawaniem, które stanowi dla Tomasza podstawowy przedmiot badań filozofa natury. Zajmuje się on odróżnieniem substancji od przypadłości, złożeniem materii i formy, czterema rodzajami przyczyn i ich wzajemnymi relacjami, a także rodzajami konieczności i identyczności.

The article discusses the problem of the christian concept of the human person in theological and philosophical context, and with reference to evolutionary sciences. It was pointed out that the naturalistic evolutionism undermines the most important assumptions (especially thesis proclaiming the unique status of human in nature), which is based on christian anthropology. In this paper it was also an attempt to justify that philosophical reflection can be important in the analysis of problems located between science and religion (among others (...) the issue of the origin, nature and destiny of man). The question about new type of christian philosophy is a challenge in theology, which will be obliged – because of the changing image of the world and man – to modify its foundations, rooted mainly in the Thomistic metaphysics so far. Besides, in the context of issues relating to the meaning of human life it indicates that there is a need to develop such a philosophy, which is based on the achievements of natural science, and would be in dialogue with the contemporary humanities.
