Across normative and empirical disciplines, considerable attention has been devoted to the prevalence and ethics of the non-medical use of prescription and illegal stimulants for neuroenhancement among students. A predominant assumption is that neuroenhancement is prevalent, in demand, and calls for appropriate policy action. In this paper, we present data on the prevalence, views and knowledge from a large sample of German students in three different universities and analyze the findings from a moral pragmatics perspective. The results of our study (...) indicate that neuroenhancement is a well-known phenomenon among German students, but not prevalent. 2.2 % of our sample reported having used a prescription medication for neuroenhancement. Exams and competitive situations were predominant motivators of use. Students were unenthusiastic and critical about neuroenhancement in the academic context and disapproved of neuroenhancement for professionals. The majority of respondents agreed that neuroenhancing substances should be regulated by the state. These stances were based on strong beliefs in resisting peer pressure, avoiding the creation of injustice and valuing of hard work. From a moral pragmatics standpoint, these results challenge the assumption that policy on neuroenhancement is necessary in academic environments. (shrink)

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.

From _Almanac of Fall_ to _The Turin Horse_, renowned Hungarian filmmaker Béla Tarr has followed the collapse of the communist promise. The “time after” is not the uniform and morose time of those who no longer believe in anything. It is the time when we are less interested in histories and their successes or failures than we are in the delicate fabric of time from which they are carved. It is the time of pure material events against which belief will (...) be measured for as long as life will sustain it. (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)

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.

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.

We give a characterization of the fixed points and of the lattices of fixed points of fuzzy Galois connections. It is shown that fixed points are naturally interpreted as concepts in the sense of traditional logic.

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)

The paper focuses on the nature and moral status of manipulation. I analyse a popular account of manipulation by Robert Noggle and assess a challenge that has been posed by Moti Gorin. I argue that Noggle’s theory can fend off the challenge. The analysis is instructive in that it enables one to look more closely at the nature of manipulation. I argue, contrary to some proposed accounts, that manipulation essentially involves deception about the manipulator’s intentions. Secondly, since manipulation contains an (...) element of deception, it is, I maintain, prima facie immoral. Finally, I analyse and explain away several examples of allegedly morally non-problematic manipulation. (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.

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.

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)

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 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)

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)

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.

An algebra with fuzzy equality is a set with operations on it that is equipped with similarity ≈, i.e. a fuzzy equivalence relation, such that each operation f is compatible with ≈. Described verbally, compatibility says that each f yields similar results if applied to pairwise similar arguments. On the one hand, algebras with fuzzy equalities are structures for the equational fragment of fuzzy logic. On the other hand, they are the formal counterpart to the intuitive idea of having functions (...) that are not allowed to map similar objects to dissimilar ones. In this paper, we present a generalization of the well-known Birkhoff’s variety theorem: a class of algebras with fuzzy equality is the class of all models of a fuzzy set of identities iff it is closed under suitably defined morphisms, substructures, and direct products.

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)

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.

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.

The work analyzes two competing arguments in the issue of abortion and shows that each requires a different theory of personal identity. Further, I analyze those theories and show what moral premises they are compatible with and what implications there are for the abortion debate.

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.

The goal of this paper is to assess three arguments that have been proposed to rebut the idea that the notion of indeterminate identity is incoherent. In the first part, the author presents Gareth Evans’ argument purporting to show the incoherence of indeterminate identity. Next, the author assesses a rebuttal proposed by E. J. Lowe. Although the rebuttal seems sound, Harold Noonan has shown that its scope is limited. After that, a rebuttal by Peter van Inwagen is analysed. The author (...) compares it with Lowe’s and shows that consistent application of the principles van Inwagen uses leads to objects having inconsistent properties. In the final part, it is shown that although the answer proposed by Terence Parsons seems superior to both van Inwagen’s and Lowe’s, its scope is also limited. As a result, Evans’ argument seems to stand unrefuted by these three counterarguments. (shrink)

This essay presents a comparison of modal theories with flexible and constant domain of individuals. Whatś called the simplest quantified modal logic represents the latter type. However, it has some controversial consequences: the fact that all objects of discourse exist necessarily, and the fact that to every merely possible object there corresponds an actual one. These drawbacks are eliminated by the Kripke models, which postulate possible worlds with a flexible domain of objects. Proponents of TIL return to the theory with (...) the constant domain and attempt to elucidate what mistakes lead Kripkeś followers to endorsement of models with the flexible domain, and explain-away the alleged problems of the constant domain. This work aims at clarifying the character of the attitude of TIL proponents and showing that the arguments for accepting the constant domain they provide are not completely satisfactory due to the role proper names play in their theory.
