The main purpose of the article is to compare the originally Greek, Plato\'s concept of dialogue and its function in the procedure of philosophying to the one developed by the 20-century \"philosophy of dialogue\" (F. Rosenzweig, M. Buber, F. Ebner, E. Levinas). It seems quite astounding that philosophy of dialogue, a trend which consistently and persistently defends the privileged position of dialogue in the structure of reality and uses it as an essential factor in the understanding of the relation between (...) God and Man, has not developed any solid methodological perspective. What is even worse, it failed to observe its presence in the very core of philosophical thinking, i.e. in Plato\'s thought. We are capable of reconstructing Plato\'s modus philosophandi with its essential conditions: the philosopher must not only \'see\' the truth (the noetical function), but must also tell it to the others, choose the partners of the dialogue and defend his logos if necessary (the apophantical function). The article consists of two complementary analyses: the first one is devoted to the presentation of the dialogical factor in Plato\'s noetics and apophantics, and the second one focuses on Rosenzweig\'s criticism of the whole European philosophy. The author tries to indicate its doubtful moments by -putting forward the question whether Plato\'s philosophy may be justly ascribed to the tradition under Rosenzweig\'s criticism, and if so, to what extent.

The paper aims at a phenomenological clarification of the “island community” category in the light of Dietrich von Hildebrand’s metaphysics of community. I begin with presenting a brief social history of the Spinalonga leprosarium as a model of an island community; then follows a sketch of some of the main findings made by the German philosopher concerning community per se, and finally an attempt is made to explain the place of island communities in Hildebrand’s hierarchy of communities. I aim to (...) show that an island community should be taken as a special example of what he calls a life circle. It is special because it somehow transcends the “primitiveness” imposed by Hildebrand on Lebenskreise in general, as a result of being rooted in a serious realm of value and meaning. (shrink)

We give a few results concerning the notions of causal completability and causal closedness of classical probability spaces . We prove that any classical probability space has a causally closed extension; any finite classical probability space with positive rational probabilities on the atoms of the event algebra can be extended to a causally up-to-three-closed finite space; and any classical probability space can be extended to a space in which all correlations between events that are logically independent modulo measure zero event (...) have a countably infinite common-cause system. Collectively, these results show that it is surprisingly easy to find Reichenbach-style ‘explanations' for correlations, underlining doubts as to whether this approach can yield a philosophically relevant account of causality. 1 Introduction2 Basic Definitions and Results in the Literature3 Causal Completability the Easy Way: ‘Splitting the Atom’4 Causal Completability of Classical Probability Spaces: The General Case5 Infinite Statistical Common-Cause Systems for Arbitrary Pairs6 ConclusionAppendix A.

In this article, we address the case of self-tracking as a practice in which two meaningful backgrounds play an important role as the spatial dimension of human practices. Using a phenomenological approach, we show how quantification multiplies backgrounds, while at the same time generating data about the user. As a result, we can no longer speak of a unified background of human activity, but of multiple dimensions of this background, which, additionally, is perceived as having no pivotal role in the (...) process, often being hidden, situated beyond human consciousness, or taken for granted. Consequently, the phenomenological experience of the background turns into a hermeneutic practice focused on the interpretation of representations and descriptions. By adopting a phenomenological approach, we show the problems and limitations of quantification of human activities occurring in self-tracking and the theoretical problems associated with the scheme of human-technology relations.

Let ΩΩ be the semigroup of all mappings of a countably infinite set Ω. If U and V are subsemigroups of ΩΩ, then we write U≈V if there exists a finite subset F of ΩΩ such that the subsemigroup generated by U and F equals that generated by V and F. The relative rank of U in ΩΩ is the least cardinality of a subset A of ΩΩ such that the union of U and A generates ΩΩ. In this paper (...) we study the notions of relative rank and the equivalence ≈ for semigroups of endomorphisms of binary relations on Ω.The semigroups of endomorphisms of preorders, bipartite graphs, and tolerances on Ω are shown to lie in two equivalence classes under ≈. Moreover such semigroups have relative rank 0, 1, 2, or in ΩΩ where is the minimum cardinality of a dominating family for . We give examples of preorders, bipartite graphs, and tolerances on Ω where the relative ranks of their endomorphism semigroups in ΩΩ are 0, 1, 2, and .We show that the endomorphism semigroups of graphs, in general, fall into at least four classes under ≈ and that there exist graphs where the relative rank of the endomorphism semigroup is 20.

Physical theories give us the best available information about what there exists. Although physics is not ontology, it can be ontologically interpreted. In the present study, I propose to interpret physical theories à la Quine, i.e. not to speculate about what really exists, but rather to identify what a given physical theory presupposes that exists. I briefly suggest how Quine’s program should by adapted to this goal. To put the idea to the test, I apply it to the famous Hartle–Hawking (...) model of the quantum creation of the universe from nothing, and try to discover what kind of nothingness the model presupposes. I also make some remarks concerning ontological commitments of the method of physics itself. (shrink)

We agree that the default numerical representation is best accessed by probing automatic processing. The locus of this representation is apparently at the horizontal intraparietal sulcus (HIPS), the convergence zone of magnitude information. The parietal lobes are the right place to look for non-abstract representation of magnitude, yet the proof for that is still to be found.

In this article, we address the case of self-tracking as a practice in which two meaningful backgrounds (physical world and technological infrastructure) play an important role as the spatial dimension of human practices. Using a (post)phenomenological approach, we show how quantification multiplies backgrounds, while at the same time generating data about the user. As a result, we can no longer speak of a unified background of human activity, but of multiple dimensions of this background, which, additionally, is perceived as having (...) no pivotal role in the process, often being hidden, situated beyond human consciousness, or taken for granted. Consequently, the phenomenological experience of the background turns into a hermeneutic practice focused on the interpretation of representations and descriptions. By adopting a (post)phenomenological approach, we show the problems and limitations of quantification of human activities occurring in self-tracking and the theoretical problems associated with the scheme of human-technology relations.

The text presents the results of a qualitative study focused on the issue of using nanomaterials in the extraordinary circumstances linked to the COVID-19 pandemic, particularly referring to the “Roušky s TULkou” initiative. Within several weeks, this initiative managed to launch the production of highly efficient nanofiber filters using the original AC Electrospinning technology on an industrial scale. The goal of the research was to analyse both the regional experience and the value-based challenges, conflicts and ethical dilemmas posed by an (...) emergency situation. The theoretical starting points of the research were the Turnerian understanding of liminality, communitas and antistructure and Stenner’s concept of liminal spaces. The results of the research show that the pandemic situation contributed to the emergence of an unexpected potential of the new technology and that the realisation of the activity was influenced not only by know-how and the university’s technical facilities, but particularly by social capital, thus uncovering the potential of the anti-structural character of the initiative and the temporary suspension of hierarchically established university structures.

In the framework of Stewart Shapiro, computations are performed directly on strings of symbols (numerals) whose abstract numerical interpretation is determined by a notation. Shapiro showed that a total unary function (unary relation) on natural numbers is computable in every injective notation if and only if it is almost constant or almost identity function (finite or co-finite set). We obtain a syntactic generalization of this theorem, in terms of quantifier-free definability, for functions and relations relatively intrinsically computable on certain types (...) of equivalence structures. We also characterize the class of relations and partial functions of arbitrary finite arities which are computable in every notation (be it injective or not). We consider the same question for notations in which certain equivalence relations are assumed to be computable. Finally, we discuss connections with a theorem by Ash, Knight, Manasse and Slaman which allow us to deduce some (but not all) of our results, based on quantifier elimination. (shrink)

This article utilises feminist technoscience studies’ notions of bodily ‘materialisation’ and ‘ontological choreographies’, offering a cyborg feminist account of ‘bioavailability’ as embodied becomings, rather than a fixed ontological state of being. Drawn from 2 years’ ethnographic study in in vitro fertilisation clinics in Spain with migrant women who provided eggs to the cross-border in vitro fertilisation industry, this work explores how global understandings of race and inequalities, clinical practices and women’s own emotional and physical labours collectively produce bioavailability. Through examples (...) from observations and interviews in in vitro fertilisation clinics, we examined women’s embodied stories to understand the ways in which bioavailability becomes. The article demonstrates a novel way in which to think about ‘bioavailability’, a concept which has already been of enormous use to the social sciences since its introduction by Lawrence Cohen. We examine recent configurations of bodily extraction in the reproduction–migration nexus that help us rethink the concept of bioavailability. (shrink)

This ground-breaking collection of essays tackles the philosophical issues at play in cosmology, physics, mathematics, and neuroscience. The book considers topics such as the presence of ontology in cosmological theory and physics. It also weighs the philosophical issues connected with mathematical method, the neuroscience of emotions, and evolutionary anthropology. The contributions look at structuralism in the Platonic philosophy of science and the issue of knowledge and faith. This book is a must read for anyone interested in the philosophy of science (...) and the increasingly blurred borders between the two. (shrink)

Our present knowledge in the field of dynamical systems, information theory, probability theory and other similar domains indicates that the human brain is a complex dynamical system working in a strong chaotic regime in which random processes play important roles. In this environment our mental life develops. To choose a logically ordered sequence from a random or almost random stream of thoughts is a difficult and energy consuming task. The only domain in which we are able to do this with (...) a full success is mathematics. Leibniz’s life ambition was to extend this success, with the help of what he called _characteristica universalis_, to other areas of human activity. The belief that this is possible lies at the basis of Leibniz’s rationalist system. Reasoning within his system, Leibniz claimed that also fundamental laws of physics can be deduced from the “first principles”. Just as linguistic or conceptual units are at the basis of the _charactersistica universalis_, his monads are responsible for physical activity of material bodies. When this rationalistic strategy is applied to the philosophy of space and time, it leads to their radically relational conception. Leibniz’s rationalistic approach to philosophy and science arouses out sympathy but it was Newton’s mathematical-empirical method that turned out to be effective in human endeavour to understand the functioning of the physical world. Successes of the Newtonian method compel us to revise our concept of rationality. (shrink)
