Instead of the existential quantifier Bernard Bolzano uses his notion of Gegenständlichkeit einer Vorstellung an sich . This approach makes it possible for him to solve the traditional problem of the predication of existence in accordance with an approach common today, namely to take existence to be primarily a property of a corresponding representation in itself, and not a characteristic of individuals. However, Bolzano considers a property of real existence to be attributable also to particular individuals, which is essentially different (...) from the usual practice. (shrink)

In his treatise Die Grundlagen der Arithmetik, Gottlob Frege tries to find a definition of number. First he rejects the idea that number could be a property of external objects. Then he comes with a suggestion that a numerical statement expresses a property of a concept, namely it indicates how many objects fall under the concept. Subsequently Frege rejects, or at least essentially modifies, also this definition, because in his view that a number cannot be a property – it should (...) be an object. In this article, I try to show that Frege’s first definition of number seems to be, despite his own opinion, much more promising than he supposed. I also argue that Frege’s argumentation against the empirical character of number is by no means convincing. (shrink)

Bernard Bolzano presents in his work Wissenschaftslehre a definition of derivability among sentences. Tarski publishes his well-known definition of logical consequence almost one hundred years later. This article intends to prove that the Bolzano´s definition is fully satisfactory compared to the Tarski´s one, even though no attention was drawn to Bolzano´s definition at that time.

The nominalist attitude in medieval logic supported a fully extensional conception of the sense of expressions. Many arguments against this approach were raised at that time. I would like to show in this article that there is a extensional conception of notions in current logic, namely in the interpretation of formal theories and the creation models of them and that, and how, traditional arguments against the extensional conception are relevant also for logic today.

Numerical identity is standardly considered to be a relation between things. This means that two things are identical if they are only one thing. It is not only Wittgenstein who finds this claim rather odd. Another possibility is to understand identity as a relation between names which denote the same thing; or as a relation between the senses of those names which are modes of presentation of the same thing. Or identity statements can be considered as expressions of the fact (...) that there is exactly one thing that has certain characteristics. These conceptions are, in fact, closely interlinked. There are some rather straightforward proposals on how to give these approaches a formal pattern in relative harmony with classical logic. What is important to emphasize and keep in mind is the specific character of identity and essential dissimilarities between identity and relations of objects in logic. (shrink)

Cantor's diagonal proof is sig­nificant both because the central method of proof used in it has been subsequently applied in a number of other proofs, and because it is considered to confirm the existence of infinite sets whose size fun­ damentally and by an order of magnitude exceeds the size of the "classical" infinite set represented by all natural numbers, while their size can theoretically exceed every conceivable limit. Although Can­tor's proof is generally accepted by the scientific community, some experts (...) are somewhat reserved about it. The aim of this paper is to present Cantor's proof in an accessible way, while pointing out its (hidden) assumptions and possible problematic points, and pointing out that some of its underlying assumptions are not indisputable mathematical truths, but rather postulated propositions that may or may not be accepted.

Recent extensional logic considers a formula containing existential quantifier as an adequate way of rewriting a statement about the existence of something. Quine even claims that “to be is to be the value of a variable”. That means that if we consider a theory to be true, we have to treat all members of an appropriate universe as existing. This article intends to point out a difficulty in this conception: The primary task of an existential quantifier is only to claim (...) that something can be found in a universe, whatever the universe is.

The notion of the extension of a concept has been used in logic for a long time. It is usually considered to be closely connected to the intuitive notion of a set and thus seems as though it should be embedded into set theory. However, there are significant differences between this “logical” concept of set and the notion of set (class) as defined via standard axiomatic systems of set theory; it may, therefore, be quite misleading to consider the two concepts (...) as being continuous with each other. When we look at the writings of Gottlob Frege and consider the development of his attitude to extensions, we can see what the differences consist in and which of the two notions is more apt to be used in foundations of logic. Frege himself eventually rejected sets entirely. (shrink)

Gottlob Frege rozlišuje mezi smyslem a významem výrazů, přičemž smyslem rozumí to, co je výrazem vyjadřováno, významem pak to, co je jím označováno. Toto rozlišení se týká jak singulárních, tak obecných výrazů, ovšem Fregovy rozbory týkající se významu obecných výrazů jsou všeobecně méně známy. Chci zdůraznit skutečnost, že Frege považuje za význam obecných výrazů pojem, který chápe jako tzv. nenasycenou funkci, nikoli jako množinu nebo zobrazení. To mu umožňuje zachovat některé podstatné intuice týkající se obecnin – můžeme např. mít obecný (...) pojem (znát nějakou vlastnost či relaci), aniž bychom věděli, jaké předměty pod něj spadají. Zároveň se snažím ukázat, že není jasné, nakolik Frege skutečně zastával tezi, která mu bývá obvykle přičítána, totiž že identita pojmů je dána jejich koextenzivitou. Gottlob Frege distinguished between sense and reference of expressions. 'Sense' according to him is that what the expression means, 'reference' is that what is designated by it. This distinction concerns both singular and general terms but Frege’s analyses focused on general terms are much less known. It is crucial, I argue, to appreciate the importance of the fact that the reference of a general term is, according to Frege, a concept – identified with an unsaturated function in the Fregean sense, i.e. not a set, and not a mapping. In this way Frege can keep some important intuitions about universals – for instance that we can have a general concept (know a property or a relation) even if we don’t know which objects fall under it. I also try to show that it is not clear whether Frege really defended the thesis usually attributed to him that the identity of concepts is guaranteed solely by their coextensivity. (shrink)

[On the Ethics of Euthanasia Again: A Reply to Critics] The article is a reply to three critics of a previous piece on the ethics of euthanasia in which I defended physician-assisted suicide. According to Ingrid Strobachová it is necessary to give a greater attention to the significance of pain, which, she claims, may benefit from a phenomenological description. According to Marta Vlasáková my argument is not valid because two principles on which it is founded – i.e. the conception (...) of life as of fundamental value and the autonomy of the patient – are not in mutual harmony. Jakub Jirsa criticises the very concept of assisted suicide and the moral legitimacy and need for the legalisation of assisted suicide. To Dr Strobachová I reply that phenomenological description is as acceptable a method as any other – as long, that is, as it is not only a verbal game, but constitutes a real source of knowledge. To Dr. Vlasáková I argue that a more charitable reading of my argument is possible. The arguments of Dr. Jirsa against assisted suicide are beset with various inconsistencies, including the fact that he himself allows that doctors should tolerate suicide by the refusal of food and drink. Such an act does not, however, differ in any relevant way from doctor-assisted suicide. (shrink)

In a series of three behavioral experiments, we found a systematic distortion of probability judgments concerning elementary visual stimuli. Participants were briefly shown a set of figures that had two features (e.g., a geometric shape and a color) with two possible values each (e.g., triangle or circle and black or white). A figure was then drawn, and participants were informed about the value of one of its features (e.g., that the figure was a “circle”) and had to predict the value (...) of the other feature (e.g., whether the figure was “black” or “white”). We repeated this procedure for various sets of figures and, by varying the statistical association between features in the sets, we manipulated the probability of a feature given the evidence of another (e.g., the posterior probability of hypothesis “black” given the evidence “circle”) as well as the support provided by a feature to another (e.g., the impact, or confirmation, of evidence “circle” on the hypothesis “black”). Results indicated that participants’ judgments were deeply affected by impact, although they only should have depended on the probability distributions over the features, and that the dissociation between evidential impact and posterior probability increased the number of errors. The implications of these findings for lower and higher level cognitive models are discussed. (shrink)

This is a study of the effects of a number of background variables on ethical perceptions of Mexican and U.S. marketers. This research investigates how a marketer’s personal religiousness, relativism, and the ethical values influence in perceptions of the degree of ethical problems in hypothetical marketing scenarios. It also examines differences between Mexican and U.S. marketers on these variables. The results show significant differences in perception between the countries, and we discuss the implications of these differences for cross-cultural business activities.

The critical discourse analysis is the tool used in this article, to study how audiovisual media have constructed mental representation about the historical facts occurred in Spain between the final stage of the Spanish Civil War and the late 1980s: the theft of newborn babies. The State has failed in an attempt to establish policies that support truth, justice and reparation as it has been recalled by United Nations experts to the Government of Spain, and the reports and documentaries have (...) become vehicles to capture and recover memories. Our objective is to analyze how this collective awareness has been realized and the contribution of reports and documentaries. Our results show that the Spanish television channels silence the Francoist context to depict the thefts as the product of economical mobs focused on child trafficking. The international channels, however, put the origin of the dictatorship at the center of the discourse. (shrink)

BackgroundUnder COVID-19 pandemic, many organizations developed guidelines to deal with the ethical aspects of resources allocation. This study describes the results of an argument-based review of ethical guidelines developed at the European level. It aims to increase knowledge and awareness about the moral relevance of the outbreak, especially as regards the balance of equity and dignity in clinical practice and patient’s care. MethodAccording to the argument-based review framework, we started our research from the following two questions: what are the ethical (...) principles adopted by the ethical guidelines produced at the beginning of the COVID-19 outbreak related to resource allocation? And what are the practical consequences in terms of 'priority' of access, access criteria, management of the decision-making process and patient care?ResultsTwenty-two ethical guidelines met our inclusion criteria and the results of our analysis are organized into 4 ethical concepts and related arguments: the equity principle and emerging ethical theories; triage criteria; respecting patient’s dignity, and decision making and quality of care.ConclusionFurther studies can investigate the practical consequences of the application of the guidelines described, in terms of quality of care and health care professionals’ moral distress.

As critical research has revealed, climate change scepticism and inaction are not about science but ideas, and specifically the ideas that conform our worldview. Drawing on key theoretical approaches to climate change denial from the social sciences and humanities, this paper discusses the ideological dimension and, more especially, the anthropocentric denial underlying our failure to respond to climate change. We argue that the speciesist anthropocentrism inherent in the current dominant ethics is what prevents humanity from reacting to the main human-induced (...) drivers of global warming. Encouraged to do so by current mainstream ethics, humans overpopulate the planet, grow at the expense of other species, and indulge in cruel, unhealthy and unsustainable practices. We counterpose this ethics against the egalitarian, non-speciesist approach of the animal ethics movement, positing that it represents the next radical reflexive movement and could be used to break the climate deadlock. Animal ethics allows links with inegalitarianism and privilege that may help address climate contrarianism and climate inaction much more effectively. (shrink)

This Chapter aims to present a very preliminary exploration of the role and functioning of some ‘leading ideas’ that represent the most consistent attempts to balance freedom of scientific research with the need to protect participants and the community as a whole. To this end, we searched two databases, a scientific and a legal one, for some keywords (Freedom of research, Precautionary principle, Risk-based approach, Responsible research and innovation), to check the consistency of their presence and evolution over time. Without (...) aiming to in-depth investigate the precise connotations of each term and the context in which they are used from time to time, the core idea is to provide a very first quantitative exploration, which lays the foundations for further future investigation.

We argue that general intelligence, as presented in the target article, generates multiple distinct and non-equivalent characterisations. Clarifying this central concept is necessary for assessing Burkart et al.’s proposal that the cultural intelligence hypothesis is the best explanation for the evolution of general intelligence. We assess this claim by considering two characterisations of general intelligence presented in the article.

We propose a new integrative framework of external time monitoring in prospective memory (PM) tasks and its relation with performance. Starting from existing empirical regularities and our theoretical analysis, the framework predicts that external monitoring in PM tasks comprises a first stage of loose monitoring to keep track of the passage of time, and a subsequent stage of finer-grained monitoring, based on interval reduction, to meet the PM deadline. Following our framework, we predicted and observed in three different datasets (N (...) = 375): (1) a marked increase in external monitoring frequency in the final part of the period of the PM task, well captured by a proportional rate exponential growth function; (2) a positive association between individual compliance with this monitoring pattern and PM performance; (3) a positive relation between monitoring frequency in the time window immediately preceding the PM deadline and PM performance at the individual level; and (4) good individual compliance with an interval reduction pattern in external monitoring, especially in the time window closer to the PM deadline. These results support the proposed integrative framework, which has the potential to foster future research on external monitoring in PM and in other fields of cognitive science. (shrink)

Resumen: El objetivo de este artículo es realizar un repaso de las teorías de las emociones más importantes de las últimas décadas y valorar en qué medida tales teorías ofrecen una buena caracterización del fenómeno en cuestión. Para alcanzar una comprensión adecuada de las diferentes teorías, así como del rumbo que ha tomado el debate actual sobre las emociones, es importante que prestemos especial atención a algunos de los compromisos filosóficos involucrados en la formulación de estas teorías. La revisión cuidadosa (...) de algunos de estos compromisos nos llevará a plantearnos si algunas de las dificultades a las que se enfrentan varias de las teorías de las emociones actuales podrían tener origen en tales compromisos filosóficos y no, como suele pensarse, en la complejidad de las emociones.: The aim of this paper is to review the most important theories of emotions in recent decades and to assess the extent to which these theories provide a good characterisation of the phenomenon in question. In order to achieve an appropriate understanding of the different theories, as well as of the direction that the current debate on emotions has taken, it is important that we pay special attention to some of the philosophical commitments involved in the formulation of these theories. Careful examination of some of these commitments will lead us to consider whether some of the difficulties faced by several of the current theories of emotions might stem from such philosophical commitments rather than, as is often thought, from the complexity of emotions.

SUMMARYEarly modern artists who did not have access to Roman Antiquity or needed quick access to it could refer to prints after monuments such as those issued by Antoine Lafréry. But Du Choul's Discours sur la castrametation et discipline militaire des Romains [ … ] De la Religion des anciens Romains was also successful among artists, particularly painters. It was in vernacular language and widely available in French, Spanish and Italian; it was affordable and compact in format ; it had (...) plenty of woodcuts; and it focused on the Roman military life, besides the monuments, for which information could also be found in travel guides. The present essay aims to study how Du Choul's volume circulated, with several examples from Spain and Italy. The Discours will be used as a case study of artists as readers, and I will study aspects previously overlooked such as the book's market price in the early modern period, examples of use of copies of the book by artists and, more broadly, the troubles and challenges encountered by these readers when representing subjects from ancient history.

Este libro propone un recorrido por la obra de Jürgen Habermas desde la atención prioritaria hacia la articulación histórica y efectiva de las identidades. Así, la versión de Habermas como representante señero de la segunda generación de la Escuela de Frankfurt es analizada atendiendo, además de a su ambición epistemológica como ciencia social, a su comprensión de los escenarios de la praxis, allí, en definitiva, donde se dilucida la posible realización de los ideales identitarios. El contraste entre la crítica de (...) Habermas a los nacionalismos obsesionados con el nexo entre pasado histórico e identidad colectiva y las comparecencias empíricas de unas voluntades políticas y sociales nacionalistas que persiguen su autodeterminación precisamente desde el reclamo de ese nexo, permite advertir los problemas de la teoría de Habermas para integrar como conocimiento las dimensiones de la realidad social que discuten su idea de un progreso dirigido hacia el universalismo. Desde ese interés principal que focaliza la presente lectura de los textos de Habermas, cobra protagonismo la reflexión acerca de la experiencia histórica y las repercusiones que la misma puede tener en la comprensión de los requerimientos de la identidad. De ahí que también tenga presencia la influencia del Holocausto en la sensibilidad teórica de un Habermas comprometido en el propósito de que sea normativamente imposible la repetición de un escenario similar. Una vez aclaradas las condiciones que influyen en la versión de Habermas acerca de los límites de la legitimidad en las apuestas identitarias, el análisis empírico del uso nacionalista del bombardeo a Gernika y de la obra de Picasso "Guernica", se presenta como un contrapunto plástico a los ideales de la teoría. Así, el recurso de la identidad colectiva vasca a ese recodo puntual de su historia se conjuga en una clave que choca con la concepción moderna sobre cómo se construye la autonomía. La evidencia de que las diversas interpretaciones inconciliables sobre el Guernica forman parte de la materialización social de una determinada convicción identitaria testifica, justamente, acerca de la necesidad de integrar en la teoría esas dimensiones de la vida social que, en efecto, chocan con la racionalidad y que, en principio, retan al sociólogo para comprender que no es lo mismo la racionalidad de su ciencia que la de su objeto de estudio.

This book proposes an approach to Eurocentrism as a paradigm of knowledge production and interpretation rooted in the Western narrative of modernity and its racial governmentalities. It contributes to the critique of the contemporary workings of Eurocentrism and racism that have frustrated the struggles for the decolonization of knowledge and continue to shape our understandings of the world order in racially hierarchical terms, by re-centering the West/Europe"--Provided by publisher.

This study compares Australian marketers with those in the United States along lines that are particular to the study of ethics. The test measured two different moral philosophies, idealism and relativism, and compared perceptions of ethical problems, ethical intentions, and corporate ethical values. According to Hofstede's cultural typologies, there should be little difference between American and Australian marketers, but the study did find significant differences. Australians tended to be more idealistic and more relativistic than Americans and the other results were (...) mixed, making it difficult to generalize about the effects of moral philosophies on the components of ethical decision-making measured here. This is an important finding; as firms become increasingly more globalized, marketers will more often be involved in cross-cultural ethical dilemmas and it seems natural to assume that similar cultures will have similar ethical orientations. That assumption may well prove erroneous. (shrink)

Analytic philosophy has recently been challenged from a perspective advocated by Richard Rorty: this favours edifying philosophy against systematic philosophy comprising also analytic philosophy. In Rorty's presentation analytic philosophy is one more variant of the Cartesian—Kantian epistemology which, being committed to a permanent framework of inquiry rooted in our human subjectivity, implies the uniqueness of one conceptual scheme.Against this tenet I argue in two ways. First, I show that analytic philosophy of mind and language with the Fregean background and possible (...) world semantics implies the pluralism of conceptual schemes on logical-conventionalist grounds. Secondly, I show that although analytic philosophy shares the claim for legitimation of a conceptual scheme with Kantian epistemology, it is critical of the latter in that the uniqueness-claim is refuted.

Some presuppositions are easier to cancel than others in embedded contexts. This contrast has been used as evidence for distinguishing two fundamentally different kinds of presuppositions, ‘soft’ and ‘hard’. ‘Soft’ presuppositions are usually assumed to arise in a pragmatic way, while ‘hard’ presuppositions are thought to be genuine semantic presuppositions. This paper argues against such a distinction and proposes to derive the difference in cancellation from inherent differences in how presupposition triggers interact with the context: their focus sensitivity, anaphoricity, and (...) question–answer congruence properties. The paper also aims to derive the presuppositions of additive particles such as too, also, again, and of it-clefts. (shrink)

This paper examines a little studied type of perspective shift that I call protagonist projection, following Holton :625–628, 1997). PP is a way of describing the mental state of a protagonist that conveys, to some extent, her perspective. Similarly to its better known cousin free indirect discourse, the shift in perspective is achieved without an overt operator. Unlike FID, PP is not based on a presumed speech-act of a protagonist. Rather, it gives a linguistic form to pre-verbal perceptual content, sensations, (...) feelings or implicit beliefs. I propose to analyse PP in a bi-contextual framework, extending Eckardt’s approach to FID. Under the resulting analysis, FID and PP are two instances of a more general category of perspective shift.

There is currently a consensus among comparative psychologists that nonhuman animals are capable of some forms of mindreading. Several philosophers and psychologists have criticized this consensus, however, arguing that there is a “logical problem” with the experimental approach used to test for mindreading in nonhuman animals. I argue that the logical problem is no more than a version of the general skeptical problem known as the theoretician’s dilemma. As such, it is not a problem that comparative psychologists must solve before (...) providing evidence for mindreading. (shrink)
