Facial perception plays a key role in various social interactions, including formidability assessments. People make relatively accurate inferences about men’s physical strength, aggressiveness, and success in physical confrontations based on facial cues. The physical factors related to the perception of fighting ability and their relative contribution have not been investigated yet, since most existing studies employed only a limited number of threat potential measures or proxies. In the present study, we collected data from Czech Mixed Martial Arts (MMA) fighters regarding (...) their fighting success and physical performance in order to test physical predictors of perceived fighting ability made on the basis of high-fidelity facial photographs. We have also explored the relationship between perceived and actual fighting ability. We created standardized 360° photographs of 44 MMA fighters which were assessed on their perceived fighting ability by 94 raters (46 males). Further, we obtained data regarding their physical characteristics (e.g. age, height, body composition) and performance (MMA score, isometric strength, anaerobic performance, lung capacity). In contrast to previous studies, we did not find any significant links between the actual and perceived fighting ability. The results of a multiple regression analysis have, however, shown that heavier fighters and those with higher anaerobic performance were judged as more successful. Our results suggest that certain physical performance-related characteristics are mirrored in individuals’ faces but assessments of fighting success based on facial cues are not congruent with actual fighting performance.

This study focuses on the origin of life as presented in the thought of Anaximander of Miletus but also points to some parallel motifs found in much later conceptions of both the pre-Darwinian German romantic science and post-Darwinian biology. According to Anaximander, life originated in the moisture associated with earth (mud). This moist environment hosted the first living creatures that later populated the dry land. In these descriptions, one can trace the earliest hints of the notion of environmental adaptation. The (...) origin of humans was seen as connected in some way with fish: ancient humans were supposed to have developed inside fish-like animals. Anaximander took into account changes in the development of living creatures (adaptations) and speculated on the origins of humans. Similar ideas are found also in the writings of much later, eighteenth and nineteenth century authors who were close to the tradition of German romantic science. We do not argue that these later concepts are in any way directly linked with those of the pre-Socratics, but they show surprising parallels in, e.g., the hypothesis that life originated in a moist environment or the supposition that human developed from fish-like ancestors. These transformations are seen as a consequence of timeless logic rather than as evolution in historical terms. Despite the accent on the origin of living things, both Anaximander and the later Naturphilosophen lack in their notions the element most characteristic of Darwin’s thought, that is, the emphasis on historicity and uniqueness of all that comes into being.

Recenzní studie vychází z kolektivní monografie editorů Charlese Bazermana, Adairy Bo- nini a Débory Figueiredo, Genre in a Changing World a věnuje se tématům souvisejícím s významem žánrů ve vědecké a akademické praxi. Identifikuje zejména dvě oblasti, na něž se ve zvýšené míře soustředí badatelské aktivity pra- cující s žánrem jako analytickým nástrojem: žánrovou pedagogiku na univerzitní úrovni a oborovou enkulturaci. Zatímco první oblast ohraničuje akademické texty vůči jiným textovým formám, druhá se zabývá jejich vnitřní rozrůzněností. Studie zdůrazňuje demonstro- vaný (...) přínos přístupů založených na žánrech pro výzkumy vědecké praxe, avšak dochází k závěru, že je zapotřebí důsledněji promýšlet jejich epistemologické implikace.

May Amusement Serve as a Social Courage Engine? According to Fredrickson's "Broaden-and-Built Theory of Positive Emotions" positive emotions have different effects in social life and are based on different mechanisms than negative emotions do. Moreover positive emotions vary among themselves - there are quality differences between them and they shall not be treated only as a single positive mood. Three simple studies presented here and inspired by the Fredrickson's theory demonstrate that amusement, in comparison to neutral condition as well as (...) to another positive emotion, may serve as a social courage engine. Amused participants were more courageous in the radio as well as in the TV interview and declared more courage in case of meeting new hypothetical person. (shrink)

Giovanni Sartori (1924-2017) was a founder and icon of contemporary political science. A number of his books and articles have become part of the theoretical and conceptual basis of the field, and of social science in general. This volume brings together selected essays that examine Sartori as a scholar, university professor and intellectual. It is unique in covering all three aspects of Sartori's academic work: comparative politics, social science methodology and political theory. General overviews of Sartori's contribution to political science (...) are complemented by chapters that focus on specific areas of his interest; and Sartori's theoretical and methodological contributions are examined alongside his extensive public appearances, which remain little known outside Italy.

In this work - both psychologists working on concepts and mathematicians working on fuzzy logic - reassess the usefulness of fuzzy logic for the psychology of concepts.

Diogenes Laertius ascribes the first concept of spherical Earth to both Pythagoras and Parmenides. Indeed, a major shift in cosmologies—emergence of the spherical conception of the Earth and the surrounding heaven—took place between the sixth and fifth centuries BCE. Given the poor state of preservation of early Pythagorean tradition, it is argued that primacy in formulating the notion of spherical Earth should be ascribed to Parmenides.

Although the theory of memetics appeared highly promising at the beginning, it is no longer considered a scientific theory among contemporary evolutionary scholars. This study aims to compare the genealogy of memetics with the historically more successful gene-culture coevolution theory. This comparison is made in order to determine the constraints that emerged during the internal development of the memetics theory that could bias memeticists to work on the ontology of meme units as opposed to hypotheses testing, which was adopted by (...) the gene-culture scholars. I trace this problem back to the diachronic development of memetics to its origin in the gene-centered anti-group-selectionist argument of George C. Williams and Richard Dawkins. The strict adoption of this argument predisposed memeticists with the a priori idea that there is no evolution without discrete units of selection, which in turn, made them dependent on the principal separation of biological and memetic fitness. This separation thus prevented memeticists from accepting an adaptationist view of culture which, on the contrary, allowed gene-culture theorists to attract more scientists to test the hypotheses, creating the historical success of the gene-culture coevolution theory.

Studie předkládá novou interpretaci zpráv o oběhu nebeských těles podle Anaximena z Mílétu. Nebeská tělesa se v jeho pojetí nemají pohybovat pod Zemí, ale naopak kolem Země. Anaximenés měl danou koncepci přiblížit motivem plstěného klobouku, který se otáčí kolem naší hlavy. Případné vysvětlení oběhů nebeských těles pomocí nakloněné Země podél její horizontální osy však patrně mylně vychází až z koncepce kulové Země a sklonu ekliptiky. Je možné, že dochované texty ve skutečnosti navazují na problém sklonu nebeské osy a popisují původní (...) situaci oběhů nebeských těles předtím, než se „nebe naklonilo“. (shrink)

A number of aspects of the cosmology of Anaximenes of Miletus have not yet been convincingly explained, but we can assume that a starting point was the notion of a universe stretching only between a flat earth and heaven. This gave the cosmology its “meteorological” character: heavenly bodies were viewed as ignited evaporations of moisture. They were thought of as moving only above the earth’s surface, and their rising and setting were explained as an optical illusion. Similar approaches appear not (...) only in the Greek epic tradition but even in the writings of Xenophanes. It can therefore be assumed that Anaximenes’s conception is representative of contemporary Ionian explanations of cosmological events. (shrink)

The article is divided into five parts that take readers through a historical and sociological analysis of the birth of European nationalism and concludes by emphasizing the need to overcome nationalism. In the first three parts, the author provides readers with detailed arguments on the historical background of nationalism. These show that the ideas of nationalism provided modern society with an important type of social bond. However, the article also focuses on why this type of social bond became the source (...) of serious trouble in central Europe. It has produced many disastrous events, such as wars, the holocaust, and ethnic-cleansing. Moreover, it has brought about a style of thinking that is too rigid and out of date in our globalizing world. The fourth part shows that nationalism operates through nationalist identity-myths. In the final part of the article, the author demonstrates how this new type of nationalism type has influenced the philosophy of education, teaching and national curricula and suggests a few maxims that should govern the transition from nationalist to trans-nationalist perspectives (not only) in education.

The paper focuses on the disproportion the author sees in Rorty’s work. While the author appreciates highly Rorty’s antirepresentationalism, he criticizes Rorty’s social and political philosophy, which, an his opinion, is rooted in early modern philosophy. The latter, he argues, emphasizes the dichotomy between subject and object – an approach characteristic for that period. In support of his claiming a big difference between full-fledge pragmatism and purely pragmatic eclecticism, the author compares Rorty’s and Dewey’s works to show that those of (...) Dewey are considerably promising as for as the resolution of the problems of our society and politics. (shrink)

We present a logic for reasoning about attribute dependencies in data involving degrees such as a degree to which an object is red or a degree to which two objects are similar. The dependencies are of the form A ⇒ B and can be interpreted in two ways: first, in data tables with entries representing degrees to which objects have attributes ; second, in database tables where each domain is equipped with a similarity relation. We assume that the degrees form (...) a scale equipped with operations representing many-valued logical connectives. If 0 and 1 are the only degrees, the algebra of degrees becomes the two-element Boolean algebra and the two interpretations become well-known dependencies in Boolean data and functional dependencies of relational databases. In a setting with general scales, we obtain a new kind of dependencies with naturally arising degrees of validity, degrees of entailment, and related logical concepts. The deduction rules of the proposed logic are inspired by Armstrong rules and make it possible to infer dependencies to degrees—the degrees of provability. We provide a soundness and completeness theorem for such a setting asserting that degrees of entailment coincide with degrees of provability, prove the independence of deduction rules, and present further observations.

This essay examines theoretical arguments surrounding the use of post-colonial theory as a way to fill in the epistemological lacuna in the studies of post-socialism. It reviews the various streams of this theoretical development and employs Edward Said’s notion of “traveling theory” to demonstrate that theoretical claims made by proponents and opponents of this particular comparative perspective are historically, socially, and geographically situated, although not fixed. Disciplinary, national, and institutional affiliations, instead of theoretical justifications, are identified as important factors in (...) the propensity to accept or resist the introduction of post-colonial perspective on Central and Eastern Europe and the former Soviet Union. The essay concludes by acknowledging the potential usefulness as well as the limits of post-colonialism in the conceptualization of the post- socialist space. (shrink)

Presented is a completeness theorem for fuzzy equational logic with truth values in a complete residuated lattice: Given a fuzzy set Σ of identities and an identity p≈q, the degree to which p≈q syntactically follows (is provable) from Σ equals the degree to which p≈q semantically follows from Σ. Pavelka style generalization of well-known Birkhoff's theorem is therefore established.

Vzrůstající využívání digitálních technologií ve vědecké práci a komunikaci vyvolává otázku, jaká je epistemologická povaha takto vytvořeného vědění. V tomto eseji využívám pojmový aparát, který vyvinuli Steven Shapin a Simon Schaffer k analýze historického sporu mezi Robertem Boylem a Thomasem Hobbesem o způsob vytváření vědění v přírodní filosofii, a aplikuji jej na problematiku digitálního výzkumu. Jejich koncepty tří technologií vytvářejících vědění – materiální, literární a sociální – se ukazují jako heuristicky užitečné koncepty i pro reflexi digitálních technologií. Ty jsou v (...) eseji představeny nikoliv jako samostatné technologie vytváření faktů, nýbrž jako prvky, kolem nichž se dosavadní vědecké technologie radikálně rekonfigurují. Zvláštní pozornost esej věnuje představě kódu jako literární technologie a roli digitálních technologií v humanitních vědách. (shrink)

Studie recenzuje následující díla: Maurice HALBWACHS, Kolektivní paměť. Praha: SLON 2009, 289 s. ; Françoise MAYER, Češi a jejich komunismus: paměť a politická identita. Praha: Argo 2009, 273 s. ; Zdeněk VAŠÍČEK – Françoise MAYER, Minulost a současnost, paměť a dějiny. Brno – Praha: CDK – Triáda 2008, 199 s. Studie konstatuje, že v češtině začíná být k dispozici dostatečné množství publikací o sociální paměti, aby teoreticky zabezpečily širší pojetí výzkumů paměti. Zároveň by však tyto výzkumy neměly být podřizovány historiografii, (...) a především je v nich zapotřebí pracovat nejen s koncepty identity a sociálních svazků, ale i moci a konfliktu. (shrink)

Humans have evolved various social behaviors such as interpersonal motor synchrony, play and sport or religious ritual that bolster group cohesion and facilitate cooperation. While important for small communities, the face-to-face nature of such technologies makes them infeasible in large-scale societies where risky cooperation between anonymous individuals must be enforced through moral judgment and, ultimately, altruistic punishment. However, the unbiased applicability of group norms is often jeopardized by moral hypocrisy, i.e., the application of moral norms in favor of closer subgroup (...) members such as key socioeconomic partners and kin. We investigated whether social behaviors that facilitate close ties between people also promote moral hypocrisy that may hamper large-scale group functioning. We recruited 129 student subjects that either interacted with a confederate in the high synchrony or low synchrony conditions or performed movements alone. Subsequently, participants judged a moral transgression committed by the confederate toward another anonymous student. The results showed that highly synchronized participants judged the confederate’s transgression less harshly than the participants in the other two conditions and that this effect was mediated by the perception of group unity with the confederate. We argue that for synchrony to amplify group identity in large-scale societies, it needs to be properly integrated with morally compelling group symbols that accentuate the group’s overarching identity. Without such contextualization, synchrony may create bonded subgroups that amplify local preferences rather than impartial and wide application of moral norms. (shrink)

The article introduces a special themed issue of Theory of Science on epistemologies of spaces and places. It provides a disciplinary context of the theme and reviews some of the key arguments that led to the so-called spatial turn in social sciences and the humanities. Science studies in the broad sense have also been affected by this shift of research interest to spatial aspects of science at both micro- and macro-levels. Scientific knowledge has been subject to analyses that stress its (...) local contingencies, mobility and dependencies on spatial arrangements. The ensuing new epistemologies require novel concepts or reconsideration of the older terms, such as universality or objectivity. (shrink)

The paper presents generalizations of results on so-called Horn logic, well-known in universal algebra, to the setting of fuzzy logic. The theories we consider consist of formulas which are implications between identities (equations) with premises weighted by truth degrees. We adopt Pavelka style: theories are fuzzy sets of formulas and we consider degrees of provability of formulas from theories. Our basic structure of truth degrees is a complete residuated lattice. We derive a Pavelka-style completeness theorem (degree of provability equals degree (...) of truth) from which we get some particular cases by imposing restrictions on the formulas under consideration. As a particular case, we obtain completeness of fuzzy equational logic. (shrink)

The paper studies closure properties of classes of fuzzy structures defined by fuzzy implicational theories, i.e. theories whose formulas are implications between fuzzy identities. We present generalizations of results from the bivalent case. Namely, we characterize model classes of general implicational theories, finitary implicational theories, and Horn theories by means of closedness under suitable algebraic constructions.

Some classical authors ascribe to Anaximander of Miletus a belief in the existence of infinite worlds. Their testimonies have provoked an extensive discussion on the question of whether Anaximander spoke of successive or coexistent worlds, or perhaps only one world that undergoes changes. Of course, this subject is related to important aspects of archaic cosmologies. First, we need to investigate whether one can even speak of a notion of coexistent worlds prior to atomist theories. Second, the issue of infinite worlds (...) is closely linked to the nature of Anaximander's scheme of the universe and Ionian cosmologies in general. Finally, this matter has a bearing on the subject of the duration or perishing of the world. (shrink)

The paper focuses on the question of whether it is morally permissible to use reproductive technologies to select children with congenital deafness. I review the arguments that have been presented to support the claims that the lack of hearing is not overall bad, that disability is caused by social discrimination rather than impairment, that the community of deaf people gives its members plenty of opportunities to lead a happy life, and that procreative decisions need not improve the world. I argue (...) that although the claims are, to a certain extent, reasonable, they fail to establish the conclusion that selecting for deafness is morally permissible. I further argue that the decision to select a deaf child is morally wrong because it results in imposed and needless dependency, that the happiness of a deaf child is conditioned by their confinement to a relatively small community, and that the deaf parents who reject their child’s potential biculturalism are motivated by questionably self-regarding reasons.

The theory of concept lattices is approached from the point of view of fuzzy logic. The notions of partial order, lattice order, and formal concept are generalized for fuzzy setting. Presented is a theorem characterizing the hierarchical structure of formal fuzzy concepts arising in a given formal fuzzy context. Also, as an application of the present approach, Dedekind–MacNeille completion of a partial fuzzy order is described. The approach and results provide foundations for formal concept analysis of vague data—the propositions “object (...) x has attribute y”, which form the input data to formal concept analysis, are now allowed to have also intermediate truth values, meeting reality better.

The article deals with a recent attack by Sam Harris on two famous arguments that purport to establish a gap between factual and evaluative statements—Hume’s Is-Ought Problem and Moore’s Open Question Argument. I present the arguments, analyze the relationship between them and critically assess Harris’ attempt to refute them. I conclude that Harris’ attempt fails.

V minulém čísle časopisu Pro-Fil uveřejnil Tomáš Sobek zajímavou stať (Sobek 2015) mapující různé odpovědi na otázku, co konstituuje lidský blahobyt neboli co je pro člověka dobré. Zatímco většina kapitol má spíše deskriptivní povahu – autor představuje jednotlivé konkurenční teorie blahobytu a zdržuje se jejich hodnocení – v poslední části předkládá tezi, podle níž existuje úzký vztah mezi lidským blahobytem a autenticitou. Mým cílem v tomto krátkém příspěvku je tuto domněnku podrobněji interpretovat a poněkud zproblematizovat. Nechci tím naznačovat, že spojení (...) blahobytu a autenticity není plodné. Spíš mne zajímá, jaký je přesně vztah mezi těmito pojmy. Sobek totiž na obecné rovině říká jen tolik, že se jednotlivé teorie blahobytu musí potýkat se stejnou otázkou, totiž s otázkou autenticity, že teorie blahobytu ztělesňují různé koncepce autenticity a že diskuze mezi teoriemi blahobytu jsou zároveň spory o to, co je to autentický život.

T. H. Macho defended the claim that politics is a system for organizing attention and for arranging relationships of visibility. One way of attracting and holding the attention of others and maintaining one’s visibility is the instrumentalization of indignation. Another way is to instigate and maintain social stress and unrest. The article explores the concepts of indignation and social stress as introduced by P. Sloterdijk. These concepts are part of a model of political dynamics that describes 1) the relationship between (...) indignation and stress in political super-units and 2) the fact that they are compensated for by means of a specific conception of individual freedom (eleuthería, J.-J. Rousseau) and a liberal social order. The article defends the claim that there is a relationship between Macho’s claim about the organization of attention, Sloterdijk’s analyses of the concept of freedom and the method whereby individuals are immunized against generated social stress, which maintains social cohesion.

The goal of the essayistic speculation (intended also as a brief laudatio) is to illustrate on an example the way that Sloterdijk could transform literary impulses into themes that he subsequently processes philosophically and develops in his works. I will present several of such potential transformations by means of parts and themes from Bonaventura’s Nachtwachen (1804, especially vigils 9 and 14), which Sloterdijk commented on in his Vienna lectures in 1998. The aim is not to seek parallels between Bonaventura’s and (...) Sloterdijk’s works, but to illustrate the possibilities of a philosophical transformation, the exploitation of literary themes by philosophical imagination and subsequently a detailed elaboration of philosophical concepts.
