In this case report, we studied Theory of Mind and figurative language comprehension in a 7.2-year-old child, conventionally named RJ, with isolated and complete agenesis of the corpus callosum, a rare malformation due to the absence of the corpus callosum, the major tract connecting the two brain hemispheres. To study ToM, which is the capability to infer the other’s mental states, we used the classical false belief tasks, and to study figurative language, i.e., those linguistic usages involving non-literal meanings, we (...) used tasks assessing metaphor and idiom comprehension. RJ’s intellectual level and his phonological, lexical, and grammatical abilities were all adequate. In both the ToM false belief tasks and novel sensory metaphor comprehension, RJ showed a delay of 3 years and a significant gap compared to a typically developing control group, while in idioms, his performance was at the border of average. These outcomes suggest that RJ has a specific pragmatic difficulty in all tasks where he must interpret the other’s communicative intention, as in ToM tasks and novel sensory metaphor comprehension. The outcomes also open up interesting insights into the relationships between ToM and figurative language in children with isolated and complete ACC. (shrink)

Wilfrid Sellars’ denunciation of the Myth of the Given was meant to clarify, against empiricism, that perceptual episodes alone are insufficient to ground and justify perceptual knowledge. Sellars showed that in order to accomplish such epistemic tasks, more resources and capacities, such as those involved in using concepts, are needed. Perceptual knowledge belongs to the space of reasons and not to an independent realm of experience. Dan Hutto and Eric Myin have recently presented the Hard Problem of Content as an (...) ensemble of reasons against naturalistic accounts of content. In a nutshell, it states that covariance relations—even though they are naturalistically acceptable explanatory resources—do not constitute content. The authors exploit this move in order to promote their preferred radical enactivist and anti-representationalist option, according to which, basic minds—the lower stratum of cognition—do not involve content. Although it is controversial to argue that the Hard Problem of Content effectively dismisses naturalistic theories of representation, a central aspect of it—the idea that information as covariance does not suffice to explain content—finds support among the defenders of classical cognitive representationalism, such as Marcin Miłkowski. This support—together with the acknowledgment this remark about covariance is a point already made by Sellars in his criticism of the Myth of the Given—has a number of interesting implications. Not only is it of interest for the debates about representationalism in cognitive science, where it can be understood as an anticipatory move, but it also offers some clues and insights for reconsidering some issues along Sellarsian lines—a conflation between two concepts of representation that is often assumed in cognitive science, a distinction between two types of relevant normativities, and a reconsideration of the naturalism involved in such explanations.

The absence of an English translation of Gonzaga's writings, both as a whole and separately, , inspired me to undertake it with the aim of making it more accessible to the public. If I were to talk briefly about the outline, the first original French version of the text appears as an anonymous author's work. In that first version signed by Sir Thomas Witth whom nothing is known about, Gonzaga doesn’t appear. His name hadn’t been appearing in the first booklet (...) for seven years until it appeared as translator in the 1807 version. Researchers concur that this was actually a trick which Gonzaga has been hiding behind because he probably never had the courage to introduce himself as the author. It is claimed that it has been conducted a lot of research in order to recover the text of Sir Thomas Witth or other possible authors with a similar name but any satisfactory solution to the riddle has not yet been given. Regarding historical data carried out during my research, I would like to offer my opinion that there is the Scottish philosophy of Common Sense hidden behind this pseudonym which deserves attention.

Orthodox decision theory is fanatical in the way it treats small probabilities of enormous value, if unbounded utility functions are allowed. Some have suggested a fix, Nicolausian discounting, according to which outcomes with small enough probabilities should be ignored when making decisions. However, there are lotteries involving only small-probability outcomes, none of which should intuitively be ignored. So the Nicolausian discounter needs a procedure for distinguishing the problematic cases of small-probability outcomes from the unproblematic ones. In this paper, I present (...) a dilemma for Nicolausian discounting: the view must be coupled either with a procedure that delivers fanatical verdicts of its own, as bad as those of orthodox decision theory, or with one that entails intransitive cyclic preferences.

Léon Brunschvicg's contribution to philosophical thought in fin-de-siècle France receives full explication in the first English-language study on his work. Arguing that Brunschvicg is crucial to understanding the philosophical schools which took root in 20th-century France, Pietro Terzi locates Brunschvicg alongside his contemporary Henri Bergson, as well as the range of thinkers he taught and influenced, including Lévinas, Merleau-Ponty, de Beauvoir, and Sartre. Brunschvicg's deep engagement with debates concerning spiritualism and rationalism, neo-Kantian philosophy, and the role of mathematics in (...) philosophy made him the perfect supervisor for a whole host of nascent philosophical ideas which were forming in the work of his students. Terzi outlines Brunchvicg's defence of neo-Kantian judgement, historical analysis and the inextricability of the natural and humanist sciences to any rigorous system of philosophy, with wide-ranging implications for contemporary scholarship.

Reciprocal libertarianism is a version of left-wing libertarianism that combines self-ownership with an egalitarian distribution of resources according to reciprocity. In this paper, I show that reciprocal libertarianism is a coherent and appealing view. I discuss how reciprocal libertarians can handle conflicts between self-ownership and reciprocity, and I show that reciprocal libertarianism can be realised in a framework of individual ownership of external resources or in a socialist scheme of common ownership (libertarian socialism). I also compare reciprocal libertarianism with left-libertarian (...) approaches: I argue that a reciprocity-sensitive version of left-libertarianism (reciprocal left-libertarianism) is coherent and morally superior to traditional left-libertarianism, on grounds of incorporating a distinctively solidaristic and recognition-oriented aspect of equality. The policy implications of reciprocal libertarianism will differ depending on which rights people can have over external resources, but all reciprocal libertarian views acknowledge the existence of social rights that people have as co-operators.

This critical essay evaluates the potential integration of distinct kinds of expertise in policymaking, especially during situations of critical emergencies, such as the COVID-19 pandemic. This article relies on two case studies: herd immunity and restricted access to ventilators for disabled people. These case studies are discussed as examples of experts’ recommendations that have not been widely accepted, though they were made within the boundaries of expert epistemic authority. While the fundamental contribution of biomedical experts in devising public health policies (...) during the COVID-19 pandemic is fully recognized, this paper intends to discuss potential issues and limitations that may arise when adopting a strict expert-based approach. By drawing attention to the interests of minorities, the paper also claims a broader notion of “relevant expertise.” This critical essay thus calls for the necessity of wider inclusiveness and representativeness in the process underlying public health policymaking.

During his late period, Nietzsche is particularly concerned with the value that mankind attributes to truth. In dealing with that topic, Nietzsche is not primarly interested in the metaphysical disputes on truth, but rather in the effects that the "will to truth" has on the human being. In fact, he argues that the "faith in a value as such of truth" influenced Western culture and started the anthropological degeneration of the human type that characterizes European morality. To call into question (...) the value of truth is therefore necessary, if one wants to help mankind to find her way in the labyrinth of nihilism. -/- In this new addition to Nietzsche scholarship, Gori explores the origin and aim of the philosopher's late perspectival thought by merging the theoretical with the historical approach, with a special focus on the epistemological debate that influenced Nietzsche. As a result, the book provides a contextual reading of the issue that supports the idea that Nietzsche’s attitude in addressing the problem of truth is, in a broad sense, pragmatic. (shrink)

This paper studies the relationship between promoting people's welfare and respecting their autonomy of choice under risk. I highlight a conflict between these two aims. Given compelling assumptions, welfarists end up disregarding people's unanimous preference, even when everyone involved is entirely rational and only concerned with maximizing their own welfare. Non-welfarist theories of social choice are then considered. They are shown to face difficulties, too: either they fail to respect the value of welfare in at least one important sense, or (...) they end up prioritizing different people's welfare differently in non-risky choices, on the basis of their attitudes to risk, which are intuitively irrelevant in this context.

The Handbook of Formal Argumentation is a community effort aimed at providing a comprehensive and up-to-date view of the state of the art and current trends in the lively research field of formal argumentation. The first volume of the Handbook is organised into five parts, containing nineteen chapters in all, each written by leading experts in the field. The first part provides a general and historical perspective on the field. The second part gives a comprehensive coverage of the argumentation formalisms (...) available in the literature at various levels of abstraction. The third part is devoted to cover some of the many dialogical aspects of argumentation, while the fourth one deals with algorithmic, computational and implementation issues. Finally, the fifth part provides some deeper analyses on the previously introduced topics. The Handbook of Formal Argumentation is an open-ended initiative of which the present volume is the first outcome. Further volumes are planned to cover topics not included in the present one and the initiative is conceived to grow by the support and feeding it receives from the community members. (shrink)

The paper provides both a description of conspiracy beliefs and an insight into their cultural significance. On one side, it highlights their specific formal features, on the other, and this constitutes its peculiarity in the recent literature on the topic, it considers them within the broader genre of general conceptual beliefs, whose main characteristics are weak methodology and logical structure, strong affective and dispositional constraints, epistemic closure and mauvaise foi, and whose main function is practical and self-representative (not epistemic). The (...) paper also claims that political theory and social sciences had some influence in legitimizing certain ideas and stereotypes that are exacerbated in conspiracy beliefs, while other te(le)ological conceptions, such as finalism and providence, may be an important source of ideas that turn out to be widely spread in contemporary criticism towards those same beliefs.

In recent years, the family of algorithms collected under the term ``deep learning'' has revolutionized artificial intelligence, enabling machines to reach human-like performances in many complex cognitive tasks. Although deep learning models are grounded in the connectionist paradigm, their recent advances were basically developed with engineering goals in mind. Despite of their applied focus, deep learning models eventually seem fruitful for cognitive purposes. This can be thought as a kind of biological exaptation, where a physiological structure becomes applicable for a (...) function different from that for which it was selected. In this paper, it will be argued that it is time for cognitive science to seriously come to terms with deep learning, and we try to spell out the reasons why this is the case. First, the path of the evolution of deep learning from the connectionist project is traced, demonstrating the remarkable continuity, and the differences as well. Then, it will be considered how deep learning models can be useful for many cognitive topics, especially those where it has achieved performance comparable to humans, from perception to language. It will be maintained that deep learning poses questions that cognitive sciences should try to answer. One of such questions is the reasons why deep convolutional models that are disembodied, inactive, unaware of context, and static, are by far the closest to the patterns of activation in the brain visual system.

The knowledge of truth, in Plato, is an experience that calls for conversion of the soul (μεταστροφή, περιστροφή). The basic feature of this experience consists in some sort of connection, which is constantly at work, between rational arguments and their non-rational conditions, briefly, lógos and páthos. How does this connection show up in Plato? Its crucial importance emerges many times at both narrative (récit) and theoretical level. In the three parts of my contribution, I show how logos-pathos intertwines with Plato's (...) notion of conversion considered as a double-sided phenomenon, as both "process" of moral education and "noetic event".

How should we choose on behalf of people with different attitudes to risk? Simon Blessenohl has recently argued that this question poses a dilemma: it seems that sometimes we must choose either acts that everyone disprefers or else acts that are sure to turn out worse than some other act. In this article, I offer a complaints-centered account of how to take people’s attitudes to risk into consideration in our decision-making, and then I show that it provides a way out (...) of Blessenohl’s dilemma.

The paper provides a thorough account of the relationship between Ernst Mach’s thought and that of an apparently more intellectually distant near-contemporary, Friedrich Nietzsche. The consistency of their views is in fact substantial, as I try to show within the paper. Despite their interests being different, both Mach and Nietzsche were concerned with the same issues about our intellectual relationship with the external world, dealing with the same questions and pursuing a common aim of eliminating worn-out philosophical conceptions. Moreover, it (...) can be argued that both Mach and Nietzsche converged on what we now know as the problem of realism versus anti-realism in the philosophy of science, and that they both rejected ‘representational’ (realist) conceptions of science in favour of a certain sort of pragmatic anti-realism, whose focus was on the role science plays as a means of orientation.

We present a logic of evidence that reduces agents’ epistemic idealisations by combining classical propositional logic with substructural modal logic for formulas in the scope of epistemic modalities. To this aim, we provide a neighborhood semantics of evidence, which provides a modal extension of Fine’s semantics for relevant propositional logic. Possible worlds semantics for classical propositional logic is then obtained by defining the set of possible worlds as a special subset of information states in Fine’s semantics. Finally, we prove that (...) evidence is a hyperintensional and non-prime notion in our logic, and provide a sound and complete axiomatisation of our evidence logic. (shrink)

This paper presents a novel argumentation framework to support Issue-Based Information System style debates on design alternatives, by providing an automatic quantitative evaluation of the positions put forward. It also identifies several formal properties of the proposed quantitative argumentation framework and compares it with existing non-numerical abstract argumentation formalisms. Finally, the paper describes the integration of the proposed approach within the design Visual Understanding Environment software tool along with three case studies in engineering design. The case studies show the potential (...) for a competitive advantage of the proposed approach with respect to state-of-the-art engineering design methods. (shrink)

In this paper I discuss the role played by Ernst Mach on Nietzsche’s thought. Starting from the contents of his Beiträge zur Analyse der Empfindungen, I’ll show the close similarities between their view on both human knowledge and the scientific world description. In his writing on science Nietzsche shares Mach’s critique to the 19th century mechanism and its metaphysical ground, as much as his way of defining the substantial notions such as matter, ego and free will. Moreover, my investigation will (...) make it clear that Mach cannot be seen as a direct source of Nietzsche’s thought, since the latter wrote many times on the same subjects long before his first reading one of his works. Rather, it is possible to consider the writings of Lange, Spir and Spencer as the first sources of Nietzsche’s views on the main themes Mach dealt with in his work from 1886. (shrink)

The conversation between Giorgio Barberio Corsetti and Pietro Montani, led by Dario Cecchi, focuses on some of the principal aspects of the career and work of Paolo Rosa and Studio Azzurro, by making reference also to the occasion when the director and the philosopher met the artist and his team. Of such an artistic path, they have been particularly emphasized the interest for the dialogue among different artistic languages (theatre, video art); the attention to the way images are able (...) to refresh the meaning of action and word within theatre and performing arts generally speaking; the relationship between art and technics in the perspective of a “poetic” (or better “poietic”) use of technologies and media; the importance given to the public (ethical and political) dimension of images and art installations, able to working through the sense of belonging to a community.

The paper investigates the epistemological and communicative competences the experts need to use and communicate evidence in the reasoning process leading to diagnosis. The diagnosis and diagnosis communication are presented as intertwined processes that should be jointly addressed in medical consultations, to empower patients’ compliance in illness management. The paper presents defeasible reasoning as specific to the diagnostic praxis, showing how this type of reasoning threatens effective diagnosis communication and entails that we should understand diagnostic evidence as defeasible as well. (...) It argues that metaphors might be effective communicative devices to let the patients understand the relevant defeasors in the diagnostic reasoning process, helping to improve effective diagnosis communication, and also encouraging a change in patients’ beliefs and attitudes on their own experience of illness and illness’ management.

During the second decade of the 20th century Hans Kleinpeter, an Austrian scholar devoted to the development of the modern science, published some brief papers on Nietzsche’s thought. Kleinpeter has been one of the main upholders of Mach’s epistemology and probably the first who connected his ideas with the philosophy of Nietzsche. In his book on Der Phänomenalismus (1913) he described a new world view that arose in the 19th century, a perspective that ‒ according to him ‒ completely contrasted (...) the mechanistic and metaphysical world view of the old school of scientific inquiry. The main outcome of the scientists whose name was related with this perspective (e.g. Clifford, Maxwell, Kirchoff and, obviously, Mach himself) has been the refusal of the absolute value of any “truth”. Kleinpeter’s statements on this topic are a good example of the rising of a Scientific Philosophy, whose development involved many scientists and thinkers that later set up the Verein Ernst Mach and the Wiener Kreis. On the other hand, his interest on Nietzsche is a relevant case of reception of the latter’s thought, that Kleinpeter puts into the context of the contemporary epistemology. In fact, he considers Nietzsche as one of the main upholders of the phenomenalistic world view, and states that he «took part at the same renewal of philosophical investigation that arose from the latest results of scientific inquiry» during the 19th century. A renewal whose main outcomes has been presented by John Stallo in his book on The Concepts and Theories of Modern Physics (1881), which Kleinpeter translated in German and published in 1901. According to Kleinpeter, in Nietzsche’s writings (mostly unpublished) one can find a theory of knowledge quite close to the one presented by both Mach and the new born Pragmatism, i.e. the complete refusal of an absolute truth and, therefore, the development of an antimetaphysical world view. In my paper I’ll discuss the main statements presented by Kleinpeter on this topic and show which of Nietzsche’s ideas has actually been in compliance with the main outcomes of late 19th century science. Thus, I’ll carry out a reconstruction of an unfamiliar side of the first period of reception of the philosophy of Nietzsche and its relevance to the development of a new (scientific) world view.

In this paper I deal with Nietzsche's theory of knowledge in the context of 19th century epistemology. In particular, I argue that, even though Nietzsche shows the ontological lack of content of truths (both on the theoretic and on the moral plane), he nevertheless leaves the space for a practical use of them, in a way that can be compared with William James' pragmatism. I thus deal with Nietzsche's and James' concept of "truth", and show their relationship with some outcomes (...) of Ernst Mach's epistemology. (shrink)

ITA: Quello del “buon europeo” è in Nietzsche un tema significativo, che si presenta originariamente connesso alle riflessioni di Nietzsche sulla cultura europea, arricchendosi col tempo di una portata filosofica che si lega agli obiettivi del suo pensiero maturo. Scopo del presente articolo è di mostrare la genesi e l’evoluzione di tale concetto, a partire dalle sue prime occorrenze in Umano, troppo umano I fino al suo compiuto sviluppo negli scritti del 1885-87. Tale studio permetterà di evidenziare il particolare valore (...) che Nietzsche attribuisce ai “buoni europei”, in quanto promotori dello sviluppo spirituale conseguente alla compiuta liberazione della morale cristiana.

That investigation shall particularly show the meaning and value that Nietzsche attributes to the good Europeans; as for him, they are in fact the leaders of the spiritual development that follows the overcoming of Christian morality.

We discuss the role of perceptron (or threshold) connectives in the context of Description Logic, and in particular their possible use as a bridge between statistical learning of models from data and logical reasoning over knowledge bases. We prove that such connectives can be added to the language of most forms of Description Logic without increasing the complexity of the corresponding inference problem. We show, with a practical example over the Gene Ontology, how even simple instances of perceptron connectives are (...) expressive enough to represent learned, complex concepts derived from real use cases. This opens up the possibility to import concepts learnt from data into existing ontologies. (shrink)

The paper addresses the issue of scientific realism in Mach, and his pragmatist approach to epistemology. Firstly, Eric Banks’s interpretation of Mach as a direct realist about particulars will be explored and discussed. Secondly, Sami Pihlström’s pragmatic realism will be considered, and it will be suggested that this view can be more viably attributed to Mach. Finally, in the light of Mach’s 1910 paper on Sensory Elements and Scientific Concepts, it will be argued that Mach’s agnosticism was probably stronger than (...) any moderate form of realism he could have been committed to, and that he was a radical pragmatist in refusing to be concerned with any kind of metaphysical issue.

How is freedom valuable? And how should we go about defining freedom? In this essay, I discuss a distinction between two general ways of valuing freedom: one appeals to the good (e.g., to freedom's contribution to well-being); the other appeals to how persons have reason to treat one another in virtue of their status as purposive beings (to the right). The analysis of these two values has many relevant implications and it is preliminary to a better understanding of the relationships (...) between freedom and justice. First, it contributes to shed light on the relationship between trust and the value of freedom, and on two attitudes towards freedom – promoting and respecting freedom. Second, it disambiguates between two versions of the claim that freedom has non-specific/content-independent value: one appeals to the good, the other to the right. And third, I show that certain implications concerning the definition of freedom follow from assuming an account of the value of freedom that exclusively appeals to the right, illustrating how the value of freedom can shape what freedom is.

Friedrich Nietzsche’s criticism towards the substance-concept „I“ plays an important role in his late thought, and can be properly understood by making reference to the 19th century debate on the scientific psychology. Friedrich Lange and Ernst Mach gave an important contribution to that debate. Both of them developed the ideas of Gustav Fechner, and thought about a „psychology without soul“, i.e. an investigation that gives up with the old metaphysics of substance in dealing with the mind-body problem. In this paper (...) I shall deal with both Lange and Mach (whose writings has been read by Nietzsche), in order to shed some light on Nietzsche’s rejection of the „I“ in philosophy. (shrink)

This paper explores Thomas Kuhn’s mature conception of incommensurable theories as collective structured lexicons that are not mutually translatable. As will be argued, his view on this issue can profitably be approached in the light of the broad pragmatist attitude that one finds at the core of Wittgenstein’s late philosophy of language, which can also consistently be ascribed to Kuhn.

The chapter explores comparatively the attention to the practical dimension that—each in his own way—Michel Foucault, Friedrich Nietzsche, and the classic pragmatist thinker William James pay when confronted with the challenge of providing a non-skeptical response to the relativist stance on truth that arose in the post-Kantian age. Particular focus will be given to the extent to which these three authors conceived of the practical framework as the only one that allows us to meaningfully address and determine truth.

Stephen Turner’s anti-normativism is based on the idea that the normative can be explained away by social science. Exploiting the idea fostered by the sociology of scientific knowledge that reasons can be understood naturalistically as the causes of the beliefs of scientists and endorsing a non-normative conception of rationality, Turner has argued that normative accounts are better understood as “Good Bad Theories” (GBT). GBT are understood as false accounts that play a role in social coordination like magical or religious rituals (...) in primitive societies (e.g. Tabu and the like). According to Turner, “norms,” “obligations,” “reasons,” and “commitments” are like Tabu and can be explained away as GBT. Hence, Turner expected normative accounts to disappear completely in a fully disenchanted world. Turner focuses on the idea, widespread among philosophers, that the normative does not reduce to the causal: his main claim is that social science succeeds in the reduction of the normative in causal terms, overcoming normative/causal dualism. Furthermore, this success is presented as creating a serious challenge for normativism. By focusing on certain (supposedly normative) features of beliefs like those involved in belief change dynamics, I will point out some interesting implications and problems for Turner’s anti-normativism.

The properties of the ${\forall^{1}}$ quantifier defined by Kontinen and Väänänen in [13] are studied, and its definition is generalized to that of a family of quantifiers ${\forall^{n}}$ . Furthermore, some epistemic operators δ n for Dependence Logic are also introduced, and the relationship between these ${\forall^{n}}$ quantifiers and the δ n operators are investigated.The Game Theoretic Semantics for Dependence Logic and the corresponding Ehrenfeucht- Fraissé game are then adapted to these new connectives.Finally, it is proved that the ${\forall^{1}}$ quantifier (...) is not uniformly definable in Dependence Logic, thus answering a question posed by Kontinen and Väänänen in the above mentioned paper.

Ineffability in Plato is a conundrum. There are at least four dimensions of ineffability in Platonic texts: epistemic (divine), strategic (religious), unspeakability and incommunicability. In this paper, I deal only with the first dimension, which is strictly epistemic in kind, and defend that Plato rejects divine ineffability, namely, the belief that the knowledge of the divine in general is inaccessible to the human mind. Several crucial passages attest to this rejection unequivocally. They show that Plato attached a great philosophical relevance (...) to what I call the equivalenceprinciple, namely, the interdependence or specularity between human and divine intelligence. The assertion of this principle represents the Platonic path to absolute knowledge, which I try to locate in the broader context of the history of philosophy, from early philosophers to Hegel.

The paper explores Nietzsche's observations on language in Human, All Too Human I, 11; reflects on the anti-realist position that Nietzsche defends in that aphorism; and focuses on the role she plays in his later investigation on Western culture and its anthropology. As will be argued, Nietzsche's criticism towards common sense realism is consistent with some pragmatist epistemologies developed during the late-nineteenth and early-twentieth century. This treat of " timeliness " does not limit Nietzsche's originality on the topic. In fact, (...) the idea that philosophy can contrast the metaphysical commitment of common sense can be seen as the theoretical tool that allows Nietzsche to operate on the development of European culture and society.

The fact that Internet companies may record our personal data and track our online behavior for commercial or political purpose has emphasized aspects related to online privacy. This has also led to the development of search engines that promise no tracking and privacy. Search engines also have a major role in spreading low-quality health information such as that of anti-vaccine websites. This study investigates the relationship between search engines’ approach to privacy and the scientific quality of the information they return. (...) We analyzed the first 30 webpages returned searching “vaccines autism” in English, Spanish, Italian, and French. The results show that not only “alternative” search engines but also other commercial engines often return more anti-vaccine pages (10–53%) than Google (0%). Some localized versions of Google, however, returned more anti-vaccine webpages (up to 10%) than Google. Health information returned by search engines has an impact on public health and, specifically, in the acceptance of vaccines. The issue of information quality when seeking information for making health-related decisions also impact the ethical aspect represented by the right to an informed consent. Our study suggests that designing a search engine that is privacy savvy and avoids issues with filter bubbles that can result from user-tracking is necessary but insufficient; instead, mechanisms should be developed to test search engines from the perspective of information quality (particularly for health-related webpages) before they can be deemed trustworthy providers of public health information.

Anaphoric deflationism is a prosententialist account of the use of “true.” Prosentences are, for sentences, the equivalent of what pronouns are for nouns: as pronouns refer to previously introduced nouns, so prosentences like “that’s true” inherit their content from previously introduced sentences. This kind of deflationism concerning the use of “true” (especially in Brandom’s version) is an explanation in terms of anaphora; the prosentence depends anaphorically on the sentence providing its content. A relevant implication of this theory is that “true” (...) is not understood as a predicate and that truth is not a property. Primitivism, defended by Frege, Moore, and Davidson, is associated with two ideas: (1) that truth is a primitive and central trait of our conceptual system and (2) that truth, as such, cannot be defined. This second claim can be called “negative primitivism,” and it especially points out the facts about the “indefinability” of truth generally advocated by primitivists. In what follows, a connection is established between the deflationist’s rejection of the predicate and of the property and facts (and primitivist ideas) about the indefinability of truth. This connection establishes a common framework to lend further explanatory power to both options. According to the resulting view, this indefinability can explain the appeal and soundness of a deflationist dismissal of predicates and properties dealing with truth. (shrink)

Hans Kleinpeter’s letters to Ernst Mach held in the Deutsches Museum Archive in Munich are of the greatest importance in order to learn some details of the relationship between these scholars. In the three letters here entirely published for the first time, Kleinpeter shows his interest for Nietzsche’s thought, and states that some of the latter’s ideas are in compliance with Mach’s epistemology.
