It is known that a countable $\omega $ -categorical structure interprets all finite structures primitively positively if and only if its polymorphism clone maps to the clone of projections on a two-element set via a continuous clone homomorphism. We investigate the relationship between the existence of a clone homomorphism to the projection clone, and the existence of such a homomorphism which is continuous and thus meets the above criterion.

This article is an attempt to examine and clarify the truth theory of American pragmatism. Three central ideas of this truth theory will be considered in light of Whitehead's metaphysics: a rejection of the correspondence theory of truth, a defense of fallibilism, and a recognition of the temporality of truth.

Excessive dog barking is among the leading sources of noise pollution world-wide; however, the reasons for the annoyance of barking to people remained uninvestigated. Our questions were: is the annoyance rating affected by the acoustic parameters of barks; does the attributed inner state of the dog and the nuisance caused by its barks correlate; does the gender and country of origin affect the subjects’ sensitivity to barking. Participants from Hungary (N = 100) and Brazil (N = 60) were tested with (...) sets of 27 artificial bark sequences. Subjects rated each bark according to the inner state of the dog and the annoyance caused by the particular bark. Subjects from both countries found high-pitched barks the most annoying: however, harsh, fast-pulsing, low-pitched barks were also unpleasant. Men found high-pitched barks more annoying than the women did. Annoyance ratings showed positive correlation with assumed negative inner states of the dog, positive emotional ratings showed negative correlation with the annoyance level. This is the first indication that acoustic features that were selected for effective vocal signalling may be annoying for human listeners. Among the explanations for this effect the role of affective communication and similar bioacoustics of particular animal vocalizations and baby cries are discussed. (shrink)

If the task of constitutional theory is to set out a language in which the discourse of constitutional law may be grounded, a question of the utmost importance is how this terminology is created, defined and interpreted. In this groundbreaking new work, András Jakab maps out and analyses the grammar and vocabulary on which the core European traditions of constitutional theory are based. He suggests understanding key constitutional concepts as responses to historical and present day challenges experienced by European (...) societies. Drawing together a great and diverse range of literature, much of which has never before been touched upon by scholarship in the English language, Jakab reconceptualises and argues for a new understanding of European constitutional law discourse. In so doing he shines new light on what constitutes its distinctively European nature. This remarkable book is essential reading for all scholars and students of constitutional theory in Europe and beyond. (shrink)

In a questionnaire study we surveyed the owners of 113 companion dogs. Owners had to mark on a four-grade scale how long their dog remembered particular memory items. Additionally we collected descriptive data on the demographical characteristics of the dog and the keeping conditions.A principal component analysis on the memory items resulted in five components. From these, two were connected to people, three other components contained individual items of memory of objects and events. Analyses of variance revealed that the dog-owner (...) relationship, the keeping conditions, age and breed of the dog affect the dogs’ memory as described by the owner. The amount of time spent together or the education of the owner had no or minimal effect on these components.Our study showed that owners form stable opinions about their dogs’ episodic memory capacity. Nevertheless, the results can be biased by such factors that affect either the owners’ opinions about their dog-companions, or the dogs’ access to particular stimuli, which can modify the formation of memory traces. In the future, these results can serve as a starting point for empirical testing of family dogs’ memory. Keywords: dogs; dog owners; memory; questionnaire. (shrink)

People seem to differ in their visual search performance involving emotionally expressive faces when these expressions are seen on faces of others close to their age compared to faces of non-peers, known as the own-age bias. This study sought to compare search advantages in angry and happy faces detected on faces of adults and children on a pool of children and adults. The goals of this study were to examine the developmental trajectory of expression recognition and examine the development of (...) an OAB. Participants were asked to find a target face displaying an emotional expression among eight neutral faces. Results showed that children and adults found happy faces significantly faster than angry and fearful faces regardless of it being present on the faces of peers or non-peers. Adults responded faster to the faces of peers regardless of the expression. Furthermore, while children detected angry faces significantly faster compared to fearful ones, we found no such difference in adults. In contrast, adults detected all expressions significantly faster when they appeared on the faces of other adults compared to the faces of children. In sum, we found evidence for development in detecting facial expressions and also an age-dependent increase in OAB. We suggest that the happy face could have an advantage in visual processing due to its importance in social situations and its overall higher frequency compared to other emotional expressions. Although we only found some evidence on the OAB, using peer or non-peer faces should be a theoretical consideration of future research because the same emotion displayed on non-peers’ compared to peers’ faces may have different implications and meanings to the perceiver.

The prevailing justification for constitutional institutions is that such institutions reflect and enable rational solutions to social problems. However, constitutions are constructed through emotionally driven processes that reflect both the public sentiments of the day and, at least to some extent, basic moral emotions. Historical examples from France and the United States demonstrate the role of such emotional processes in shaping the design of liberal constitutionalism. Further, constitutional law both sets and regulates emotional display rules; favors or disfavors certain emotional (...) commitments; and, particularly through the formulation of fundamental human rights, reflects and shapes emotional moral judgments. The emotional contributors to constitutional design and interpretation may be called “constitutional sentiments.”. (shrink)

A simple inductive argument shows natural languages to have infinitly many sentences, but workers in the field have uncovered clear evidence of a diverse group of ‘exceptional’ languages from Proto-Uralic to Dyirbal and most recently, Pirahã, that appear to lack recursive devices entirely. We argue that in an information-theoretic setting non-recursive natural languages appear neither exceptional nor functionally inferior to the recursive majority.

This paper argues that emotions can play an epistemic role as justifiers of evaluative beliefs. It also presents the heuristics theory of emotion as an empirically informed explanation of how emotions can play such a role and why they in practice usefully complement non-affective evaluative judgments. As such, the heuristics theory represents a form of moderate rationalism: it acknowledges that emotions can be epistemically valuable, even privileged in some sense, but denies that they would be uniquely privileged. I argue that (...) judgments and emotional responses pick out different but correlated kinds of evaluative properties and therefore emotional responses and non-affective evaluative judgments play mutually complementary rather than mutually exclusive roles. It follows that emotional responses can be legitimately drawn upon to support evaluative beliefs, but they lack supreme epistemic authority. (shrink)

Climate change has historically been an evolutionary determinant for our species, affecting both hominin evolutionary innovations and extinction rates, and the early waves of migration and expansion outside Africa. Today Homo sapiens has turned itself into a major geological force, able to cause a biodiversity crisis comparable to previous mass extinction events, shaping the Earth surface and impacting biogeochemical cycles and the climate at a global level. We argue that anthropogenically-driven climate change must be understood in terms of a monumental (...) niche construction process, generating long-term ecological inheritance and eco-evolutionary feedbacks that are putting our health and well-being and those of future generations at risk. We then list five major sources of climate change counter-intuitiveness, highlighting how evolved cognitive biases and heuristics may stand in the way of providing effective responses within tight deadlines. Drawing on our framing of the climate breakdown, we finally call for an evolutionary perspective in approaching the adaptive challenge posed by climate change: we argue that putting the brakes on a genuine self-endangering evolutionary trap ultimately depends on our counteractive niche constructing abilities, played at the level of our institutional and innovation capacity.

Neanderthal extinction is a matter of intense debate. It has been suggested that demography (as opposed to environment or competition) could alone provide a sufficient explanation for the phenomenon. We argue that demography cannot be a ‘stand-alone’ or ‘alternative’ explanation of token extinctions as demographic features are entangled with competitive and environmental factors, and further because demography should not be conflated with neutrality.

Sentimentalists believe that values are crucially dependent on emotions. Epistemic sentimentalists subscribe to what I call the final-court-of-appeal view: emotional experience is ultimately necessary and can be sufficient for the justification of evaluative beliefs. This paper rejects this view defending a moderate version of rationalism that steers clear of the excesses of both “Stoic” rationalism and epistemic sentimentalism. We should grant that emotions play a significant epistemic role in justifying evaluations. At the same time, evaluative justification is not uniquely or (...) especially dependent on emotions. The anti-sentimentalist argument developed in this paper is based on the indeterminacy thesis. The thesis states that the evaluative properties picked out by our emotional responses are too indeterminate to play a central role in our evaluative practices. I argue that while the indeterminacy thesis undermines the final-court-of-appeal view it supports the claim that emotional responses can provide prima facie justification for evaluative beliefs.

This article deals with some phenomena of the Hungarian legal language from a historical point of view, with special regard to the terminology of private law going back to Roman law tradition. The author aims, on the one hand, to present the historical background of the current terminology of Hungarian private law by means of some representative examples. On the other hand, it is attempted at demonstrating that “false friends” and some further misunderstandings in the current terminology of Hungarian private (...) law can be led back to the historical determination of the concepts/terms in question. A certain Hungarian legal language existed already in the 16th c., however it reached the common European level by the middle of the 19th c. This development took place mainly under the influence of the Austrian and German law and legal science. Due to the translation of foreign legal terms to Hungarian since the 19th c. there emerged some “global” difficulties of legal terminology also in the Hungarian legal language. As the most important example, the reception of bona fides can be mentioned. It was an amendment of the Hungarian Civil Code in 2006 which tried to eliminate the misunderstandings as regards the principle of good faith conceived formerly by many Hungarian jurists exclusively in subjective sense. The history of reception of the German notions of Gültigkeit and Wirksamkeit in Hungary is extremely intriguing, too. Hungarian jurists did not follow the pattern of the German BGB but developed this pair created by Windscheid by drawing a clear distinction between the validity and effectiveness of legal transactions, similar to the Italian terminology. Sometimes the reception of German notions happened in a less successful way. Despite the important foreign, especially German impacts, the Hungarian legal language is an autonomous one having several remarkable features which deserve attention also in comparison with terminology of the Western legal cultures.

Mutually beneficial exchanges in markets can be exploitative because one party takes advantage of an underlying injustice. For instance, employers of sweatshop workers are often accused of exploiting the desperate conditions of their employees, although the latter accept the terms of their employment voluntarily. A weakness of this account of exploitation is its tendency for over-inclusiveness. Certainly, given the prevalence of global and domestic socioeconomic inequalities, not all exchanges that take place against background injustices should be considered exploitative. This paper (...) offers a framework to identify exploitation in mutually beneficial exchange, focusing on the case of sweatshop labor. It argues that an employer can be viewed as taking unfair advantage of an underlying injustice if and only if the employer’s surplus from the exchange in the unjust state of affairs exceeds the surplus it could maximally obtain in a just state of affairs. The paper illustrates the applicability of this framework using three different conceptions of justice and argues that it is superior to microlevel accounts of exploitation that regard background justice as irrelevant. The paper concludes by describing some normative implications that follow from judging an exchange exploitative. (shrink)

“I also talked to Buber yesterday; as a person he is lively and simple and remarkable, and seems to have nothing to do with the lukewarm things he has written” – wrote Franz Kafka to his fiancée Felice Bauer in the early 1913. What is the meaning of this harsh, yet respectful portraiture of Buber? Was it a casual ironic remark – or was it rather the way Kafka really thought of Martin Buber? And to what extent was Kafka important (...) for Buber? How can we understand the collaboration between the writer and philosopher? Close reading, contextualization and Begegnungsereignis. (shrink)
