Paraconsistent Weak Kleene logic is the 3-valued logic with two designated values defined through the weak Kleene tables. This paper is a first attempt to investigate PWK within the perspective and methods of abstract algebraic logic. We give a Hilbert-style system for PWK and prove a normal form theorem. We examine some algebraic structures for PWK, called involutive bisemilattices, showing that they are distributive as bisemilattices and that they form a variety, \, generated by the 3-element algebra WK; we also (...) prove that every involutive bisemilattice is representable as the Płonka sum over a direct system of Boolean algebras. We then study PWK from the viewpoint of AAL. We show that \ is not the equivalent algebraic semantics of any algebraisable logic and that PWK is neither protoalgebraic nor selfextensional, not assertional, but it is truth-equational. We fully characterise the deductive filters of PWK on members of \ and the reduced matrix models of PWK. Finally, we investigate PWK with the methods of second-order AAL—we describe the class \ of PWK-algebras, algebra reducts of basic full generalised matrix models of PWK, showing that they coincide with the quasivariety generated by WK—which differs from \—and explicitly providing a quasiequational basis for it.

I argue that some utterances of sentences containing occurrences of indexical expressions should not be evaluated with respect to the context of utterance. I suggest that we distinguish between context of utterance and context of interpret‐ation, and I employ this distinction in the analysis of recorded messages and other interesting linguistic phenomena. I then discuss the implications of my views on contexts with respect to the logic of indexicals. Against the traditional view, I argue that sentences such as ‘I am (...) here now’ or ‘something exists’ should not be treated as logical truths. (shrink)

In current philosophical discussions on evidence in the medical sciences, epidemiology has been used to exemplify a specific version of evidential pluralism. According to this view, known as the Russo–Williamson Thesis, evidence of both difference-making and mechanisms is produced to make causal claims in the health sciences. In this paper, I present an analysis of data and evidence in epidemiological practice, with a special focus on research on the exposome, and I cast doubt on the extent to which evidential pluralism (...) holds in this case. I start by focusing on the claim that molecular data allows for the production of mechanistic evidence. On the basis of a close look at the ways in which molecular data is used in exposome research, I caution against interpretations in terms of mechanistic evidence. Secondly, I expand my critical remarks on the thesis by addressing the conditions under which data is categorised as evidence in exposome research. I argue that these show that the classification of a dataset as a type of evidence is dependent on the ways in which the data is used. This is in contrast with the approach of evidential pluralism, where evidence is classified in different types on the basis of its intrinsic properties. Finally, I come back to what I consider the core of the thesis and suggest that the epidemiological research analysed in the paper indicates different interpretations of evidential pluralism and its applicability in the health sciences.

Recently, it has been argued that the use of Big Data transforms the sciences, making data-driven research possible and studying causality redundant. In this paper, I focus on the claim on causal knowledge by examining the Big Data project EXPOsOMICS, whose research is funded by the European Commission and considered capable of improving our understanding of the relation between exposure and disease. While EXPOsOMICS may seem the perfect exemplification of the data-driven view, I show how causal knowledge is necessary for (...) the project, both as a source for handling complexity and as an output for meeting the project’s goals. Consequently, I argue that data-driven claims about causality are fundamentally flawed and causal knowledge should be considered a necessary aspect of Big Data science. In addition, I present the consequences of this result on other data-driven claims, concerning the role of theoretical considerations. I argue that the importance of causal knowledge and other kinds of theoretical engagement in EXPOsOMICS undermine theory-free accounts and suggest alternative ways of framing science based on Big Data.

Perceptual similarity is one of the most fiercely debated topics in the philosophy and psychology of perception. The documented history of the issue spans all the way from Plato – who regarded similarity as a key factor for human perceptual experience and cognition – through to contemporary psychologists – who have tried to determine whether, and if so, how similarity relationships can be established between stimuli both within and across the senses. Recent research on cross-sensory associations, otherwise known as crossmodal (...) correspondences – that is, the existence of observable consensual associations, or mappings, between stimuli across different senses – represents an especially interesting field in which to study perceptual similarity. In fact, most accounts of crossmodal association that have been put forward in the literature to date evoke perceptual similarity as a key explanatory factor mediating the underlying association. At the same time, however, these various accounts raise several important theoretical questions concerning the very nature of similarity, with, for example, the sensory, affective, or cognitive underpinnings of similarity judgements remaining unclear. We attempt to shed light on these questions by examining the various accounts of crossmodal associations that have been put forward in the literature. Our suggestion is that perceptual similarity varies from being phenomenologically-based to conceptually-based. In particular, we propose that the nature of the associations underlying similarity judgements – whether these associations are phenomenologically-, structurally-, emotionally-, or conceptually-based – may be represented in a two-dimensional space with associative strength on one axis, and cognitive penetrability on the other.

In this paper, I will establish a conversation between Rorty and the recent proposal of post-critical pedagogy. The assumption is that through this dialogue some tenets of the latter could find a Rortyan redescription that avoids the risk of ‘metaphysical’ formulations, whereas Rorty’s ideas can increase in their relevance with respect to education thanks to the post-critical perspective. In particular, the conversation will develop by focusing on the shared attitude towards the critical-negative attitude of poststructuralist thought, the significance of the (...) subject-matter in education and an interpretation of pedagogical hermeneutics (a key notion of post-critical pedagogy) through the lens of the Rortyan idea of edification. In the conclusion, by distinguishing two views of hope – an eventist and a transitionalist – it is argued that it is precisely in this theme, which seems to be a privileged meeting ground for Rorty and post-critical pedagogy, that there may lie a major fault line.

Recent animal research suggests that it may soon be possible to support the human fetus in an artificial uterine environment for part of a pregnancy. A technique of extending gestation in this way (“ectogestation”) could be offered to parents of extremely premature infants (EPIs) to improve outcomes for their child. The use of artificial uteruses for ectogestation could generate ethical questions because of the technology’s potential impact on the point of “viability”—loosely defined as the stage of pregnancy beyond which the (...) fetus may survive external to the womb. Several medical decisions during the perinatal period are based on the gestation at which infants are considered viable, for example decisions about newborn resuscitation and abortion, and ectogestation has the potential to impact on these. Despite these possible implications, there is little existing evidence or analysis of how this technology would affect medical practice. In this paper, we combine empirical data with ethical analysis. We report a survey of 91 practicing Australian obstetricians and neonatologists; we aimed to assess their conceptual understanding of “viability,” and what ethical consequences they envisage arising from improved survival of EPIs. We also assess what the ethical implications of extending gestation should be for newborn and obstetric care. We analyze the concept of viability and argue that while ectogestation might have implications for the permissibility of neonatal life‐prolonging treatment at extremely early gestation, it should not necessarily have implications for abortion policy. We compare our ethical findings with the results of the survey. (shrink)

Humans are always interested in distinguishing natural and artificial entities although there is no sharp demarcation between the two categories. Surprisingly, things do not improve when the second type of entities is restricted to the arguably more constrained realm of physical technical artifacts. This paper helps to clarify the relationship between natural entities and technical artifacts by developing a conceptual landscape within which to analyze these notions. The framework is developed by studying three definitions of technical artifact which arise from (...) different perspectives. All these perspectives share two intuitions: that technical artifacts are physical objects that exist by human intervention; and that technical artifacts are entities to be contrasted to natural entities. Yet the perspectives are different in the way they spell out these intuitions: the relevant human intervention may range from intentional selection to intentional production; and the contrast between technical artifacts and natural entities may be introduced by a constitution relation or by defining properties that set technical artifacts apart. The three perspectives are compared and their similarities and dissimilarities are explored with the help of ontological analysis. (shrink)

Kant's Notion of "Transcendental Truth". [English] The aim of this work is to elucidate the notion of “transcendental truth” and to show its role in the Kantian system. I will argue that this notion is in line with the traditional definition of truth, i.e., that it consists in the correspondence between knowledge and object. I will also argue that criteria of transcendental truth are provided by transcendental logic, and that it is this notion of truth what makes it possible to (...) establish the truth of a priori knowledge and delimitate the field of empirical truth.

One of the main positions in the contemporary debate on joint attention is John Campbell’s relationalist account. This account has been welcomed as extremely promising in some strands of philosophy and cognitive science, but it has recently been subject to renewed criticism. In this paper, I take a sympathetic approach toward Campbell’s relationalism and I provide support for it by means of a naturalistic theory of the individuation of joint-attentional states. I start from examining some recent objections raised against Campbell’s (...) account. I suggest that, although these objections do not undermine the account, they point to questions that current relationalism leaves unanswered. Specifically, current relationalism does not provide an explanation of the psychological processes through which a joint-attentional experience is individuated, i.e., assembled and experienced, in such a way that it can constitute an immediate justification for a coordinated action. I propose that such an explanation can be found in a phenomenological-interactionist approach to shared intentionality. (shrink)

Bochvar algebras consist of the quasivariety $\mathsf {BCA}$ playing the role of equivalent algebraic semantics for Bochvar (external) logic, a logical formalism introduced by Bochvar [4] in the realm of (weak) Kleene logics. In this paper, we provide an algebraic investigation of the structure of Bochvar algebras. In particular, we prove a representation theorem based on Płonka sums and investigate the lattice of subquasivarieties, showing that Bochvar (external) logic has only one proper extension (apart from classical logic), algebraized by the (...) subquasivariety $\mathsf {NBCA}$ of $\mathsf {BCA}$. Furthermore, we address the problem of (passive) structural completeness ((P)SC) for each of them, showing that $\mathsf {NBCA}$ is SC, while $\mathsf {BCA}$ is not even PSC. Finally, we prove that both $\mathsf {BCA}$ and $\mathsf {NBCA}$ enjoy the amalgamation property (AP). (shrink)

Schnieder (2020) argues, against Orilia (2009) and Koslicki (2013), that claims of existential grounding of the form “the fact that x exists is grounded in the fact that y is F” cannot be grounded in claims of existential dependence of the form “x existentially depends on y” and defends the view that the latter claims are grounded, via a definition of existential dependence, in the former. I will firstly argue that Schnieder’s main point against the claim that existential grounding is (...) grounded in existential dependence is not conclusive; I will then put forward a proposal concerning how claims of existential grounding can be grounded in claims of existential dependence. The proposal is a third way between those of Schnieder and Orilia/Koslicki which, although accepting the former’s definition of existential dependence in terms of grounding, makes room for the latter’s idea that existential dependence does the real job in structuring reality.

Despite the proliferation of sharing economy initiatives in agri-food systems, the recent literature has still not unravelled what sharing exactly entails from an organizational standpoint. In light of this knowledge gap, this study aims to understand which resources are shared, and how, in a heterogeneous set of sharing economy initiatives in the context of food and agriculture. Specifically, this study compares the organization of various forms of alternative food networks (AFNs), which are recognized to be frugal forms of sharing economy (...) initiatives (i.e., locally based, small-scale and with limited use of information technology), in terms of leadership, bureaucracy, shared resources and participants’ engagement. Data from a comparative case study across 18 AFNs identify five sharing economy models of AFNs with distinctive shared resources and organizational mechanisms: consumer groups; commercial community gardens; as well as network-based, privately owned and publicly owned self-consumption community gardens. These models also display notable differences in terms of their origins, participants’ goals and constraints which, to some extent, may be associated to the nature of their organization. Findings inform policy-makers, AFNs’ leaders and stakeholders—especially those seeking to support innovative models towards sustainable transitions—on how to tailor institutional norms and develop networks to meet the heterogeneous needs of different typologies of sharing economy initiatives in agri-food systems.

In this paper, I address the question of how emotional qualities can be attributed to musical timbre, an acoustic feature that has proven challenging to explain using traditional accounts of musical emotions. I begin presenting the notion of musical expressiveness, as it has been conceived by cognitivists to account for the emotional quality of various musical elements like melody and rhythm. However, I also point out some limitations in these accounts, which hinder their ability to fully elucidate the emotional expressiveness (...) of timbre, especially when considering it as a result of non-cognitively mediated processes. Consequently, I explore the link between timbre and atmosphere by reviewing anecdotal sources that have characterized timbre in terms of atmosphere. The goal here is to determine if these characterizations should be seen as merely allusive and metaphoric expressions or if they genuinely reveal essential properties of timbre. To achieve this goal, I delve deeper into the notion of atmosphere, and I show that it shares several key traits with the notion of musical emotions as conceived in the cognitivist’s account. Both musical emotions and atmospheres are affectively charged externalities that are apprehended by the subject without cognitive mediation. Drawing from this insight, I conclude that the notion of atmosphere can serve as a valuable tool in explaining the emotional expressivity of timbre without invoking the resemblance-based mechanisms often found in cognitive accounts of expressiveness.

We present a possible computational content of the negative translation of classical analysis with the Axiom of (countable) Choice. Interestingly, this interpretation uses a refinement of the realizability semantics of the absurdity proposition, which is not interpreted as the empty type here. We also show how to compute witnesses from proofs in classical analysis of ∃-statements and how to extract algorithms from proofs of ∀∃-statements. Our interpretation seems computationally more direct than the one based on Godel's Dialectica interpretation.

The concept of second nature has a long and complex history, having been widely employed by several philosophers and even scientists. In recent times, the most famous thinker who has employed the concept of second nature, and has actually grounded his philosophical program precisely on this notion, is probably John McDowell. However, it is also possible to find some occurrences of the concept of second nature, “zweite Natur”, in Nietzsche’s writings, both published and unpublished. In this contribution I will develop (...) a discussion of this important topic, the nature of the human being, in Nietzsche and McDowell, and attempt to establish a comparison between them on the basis of this concept. It is the guiding idea of this article that McDowell’s “Naturalism of Second Nature”, though representing one of the most original and indeed ambitious philosophical programs today, actually suffers from some problems in defining the peculiar nature of the human being, and that referring to some of Nietzsche’s ideas on this topic may be of help in order to broaden and strengthen McDowell’s own philosophical perspective. There is almost no reference to Nietzsche in McDowell’s several philosophical works, notwithstanding his great interest in, and his careful attention to, other authors belonging to the tradition of modern German philosophy, and nobody has inquired yet into the potential Nietzsche/McDowell relationship. The paper will trace the development of certain philosophical-anthropological insights from 19th- and 20th-century German thought up to the present age, and provide an original and relevant contribution both to the specific field of Nietzsche studies and to the more general domain of inquiries into contemporary philosophical problems. Comparing the ideas of Nietzsche/ McDowell on the question concerning the nature of the human being relationship is intriguing from a philosophical point of view and may lead to a better understanding of this subject and disclose new perspectives in this field. There is a lot of philosophical insight to be gained in comparing these two figures. (shrink)

This essay is devoted to an analysis of the semantic significance of a fashionable view of proper names, the Predicate Theory of names, typically developed in the direction of the Metalinguistic Theory of names. According to MT, ‘syntactic evidence supports the conclusion that a name such as ‘Kennedy’ is analyzable in terms of the predicate ‘individual named ‘Kennedy’’. This analysis is in turn alleged to support a descriptivist treatment of proper names in designative position, presumably in contrast with theories of (...) names as ‘directly referring rigid designators’. The main aim of this essay is that of questioning the significance of PT and MT as theories of designation: even granting for the argument’s sake that names are analyzable as predicates, their designative occurrences may be interpreted in consonance with the dictates of Direct Reference—indeed, in consonance with the radically anti-descriptivist version of Direct Reference I call Millianism.

We also reduce the notion of logical consequence in to the same (...) notion in a suitable finite set of finite-valued ukasiewicz logics. Finally, we define an analytic and internal sequent calculus for infinite-valued ukasiewicz logic. (shrink)

In this article, the theory of argumentation set out by the Dutch scholars Frans van Eemeren and Rob Grootendorst is brought to bear in subjecting the general form of the argument from coherence to a critical analysis. First, a distinction is brought out between two basic kinds of argument from coherence: in one use this argumentative structure occurs as a sequence of two arguments establishing that a standpoint constitutes a particular instantiation or a inherent quality of the system it will (...) become part of (symptomatic argument); in the other use we have a main symptomatic argument supported by a subordinate argument appealing to instrumental considerations (pragmatic argument). It is then claimed that arguments from coherence are complex types of argumentation, structured at various argumentative levels, where the premises must be taken together to yield an adequate defence of the conclusion (coordinative argumentation). Finally, an evaluative assessment is made as to whether arguments from coherence can serve acceptably as tools for settling disputes: it will be maintained that we can generally welcome these argumentative structures as sound and fully acceptable provided we are aware of the interpretive discretion their use entails.

If the ancient Stoics conceived passion as a judgment or the consequence of a judgment referring to external reality, it is correct to define their conception of the psyche as ‘monistic’; it is very different if we consider that passion is due to another faculty independent of reason. In this second case, a scenario opens up in which a realistic and ‘reified’ conception of passion emerges. With reference to this, in theLetter113 Seneca discusses the paradoxical thesis of the ancient Stoic (...) scholars according to whom “the soul is an animal”, just as virtues and passions are. Through a series of close logical arguments, he shows the absurdities that can be reached in this way. By comparing this letter with theDe irawe can define the position of Seneca as a type of practical/operational imaginary dualism: the development of an original coherent form of monism. Not to give in to passion (for example to anger or libido) will not be just or not so much a psychological exercise of reason and will, but certainly a physical experience of resistance. (shrink)

Odour-sound correspondences provide some of the most fascinating and intriguing examples of crossmodal associations, in part, because it is unclear from where exactly they originate. Although frequently used as similes, or figures of speech, in both literature and poetry, such smell-sound correspondences have recently started to attract the attention of experimental researchers too. To date, the findings clearly demonstrate that the majority of non-synaesthetic individuals associate orthonasally-presented odours with various different sound properties, e.g., pitch, instrument type, and timbre, in a (...) non-random manner. What is more, these auditory-olfactory associations exhibit a number of features that are common to other crossmodal associations, such as their consistency over time, and their bidirectionality. However, the psychological mechanism underpinning these associations in the general population remain unclear, with a number of distinct hypotheses having been put forward over the years. In this chapter, we consider auditory-olfactory associations in art and science, focusing on poetry, music composition, and performance. First, we provide examples of the use of auditory-olfactory synaesthetic metaphors in poetry, from William Shakespeare through to Romanticism, illustrating how crossmodal associations have appeared in literature for centuries. Then, we move on to focus on music composition and performance, describing a number of examples where auditory stimuli have been purposely matched with crossmodally corresponding olfactory and/or visual stimuli. Considering the scientific study of smell-sound correspondences, we review the key psychophysical studies demonstrating that, beyond the artistic context, robust and non-random crossmodal associations are also triggered in the majority of the general population. We discuss a number of hypotheses that have been put forward over the years to account for such associations, focusing on the idea that certain correspondences between olfactory and auditory stimuli are mediated by the emotional character of the component stimuli.

This essay focuses on a little-understood phase of Franco Moretti’s work that spans 1976 to 1986. My aim is to shed light on Moretti’s cultural background as it was formed in that period and to account for the transition from the Trotskyist, politically-militant stance of his first book, Literature and Ideologies in England in the 1930s, to the idiosyncratic, seemingly disengaged character of Signs Taken for Wonders and The Way of the World. Adorno’s concept of ‘unrestrained individuation’ plays a crucial (...) role in the argument. Following a personal political crisis, Moretti opted to enact a form of critical individuation, encoding the explicit social antagonism of the earlier years within a highly personal style and a new theoretical eclecticism. In this way, by disguising it as an alluring form of individualism, Moretti managed to smuggle an antagonistic critical discourse into an increasingly neoliberal world that would soon prove hostile toward it.

Through a comparison between Arthur Danto’s philosophy of art and Kantian aesthetic reflection, this article identifies the place from which Danto can underestimate the aesthetic experience and its alleged irrelevance in relation to art. I argue, first, that this position of Danto is crossed by some internal contradictions in his thought. Furthermore, based on the comparison with Kant, I examine the thesis of the “end of the history of art” advanced by Danto, considering in particular two aspects. I argue: (a) (...) that Danto surreptitiously or parasitically uses in his critical activity a notion of aesthetic experience which his philosophical argument, and in particular his “aesthetic of meanings”, cannot legitimize; (b) that his thesis relating to the end of art history is symptomatic of a wider problem, which involves our forms of life, and which finds a particularly significant statement in Friedrich von Hayek’s neoliberal thought. The attempt at a neoliberal anthropology of homo œconomicus implies the tendency to absorb within it the very meaning of the experience that has long been at the center of aesthetic and artistic experience. This totalizing colonization of human forms of life appropriates some exemplary characteristics of aesthetic and artistic experience, perverting them, starting with the presumed generation of spontaneous orders, which we know are framed in an ideological horizon that is anything but obvious or natural. My thesis is that Danto’s idea of a post-historical art is one of the symptoms of this condition. (shrink)

The discussion on the 900 Conclusiones projected and sponsored by Giovanni Pico della Mirandola in Rome was cut short by the condemnation of 13 of them by the papal commission in 1487. Princeps Concordiae’s counter-arguments presented in his Apologia, published in the same year, can not be certainly considered a disputatio as Pico had called for; the papal intervention removed in this way the possibility to have a better acquaintance with a work which is still a very difficult one, just (...) for its “unfinished” form. Pedro Garsia’s Determinationes magistrales against Pico’s Apologia are a very poor reply to Pico. In this paper Pico’s arguments against some of the condemned Conclusiones are considered as well as Pedro Garsia’s counter-arguments. Giovanni Pico della Mirandola displays a deep familiarity with medieval logical and semantical doctrines, while Pedro Garsia’s arguments betray a solid ignorance. (shrink)

According to a popular approach to the ontology of music, the identity conditions for a musical work include the specification of properties of sound, which constrain the class of its correct performances.

Words sound slightly different each time they are said, both by the same talker and across talkers. Rather than hurting learning, lab studies suggest that talker variability helps infants learn similar sounding words. However, very little is known about how much variability infants hear within a single talker or across talkers in naturalistic input. Here, we quantified these types of talker variability for highly frequent words spoken to 44 infants, from naturalistic recordings sampled longitudinally over a year of life (from (...) 6 to 17 months). We used non‐contrastive acoustic measurements (e.g., mean pitch, duration, harmonics‐to‐noise ratio) and holistic measures of sound similarity (normalized acoustic distance) to quantify acoustic variability. We find three key results. First, pitch‐based variability was generally lower for infants' top talkers than across their other talkers, but overall acoustic distance is higher for tokens from the top talker versus the others. Second, the amount of acoustic variability infants heard could not be predicted from, and thus was not redundant with, other properties of the input such as the number of talkers or tokens, or proportion of speech from particular sources (e.g., women, children, electronics). Finally, we find that patterns of pitch‐based acoustic variability heard in naturalistic input were similar to those found with in‐lab stimuli that facilitated word learning. This large‐scale quantification of talker variability in infants' everyday input sets the stage for linking naturally occurring variability “in the wild” to early word learning. (shrink)

The focus of this monograph lies in the construction of a theory of legal obligation, understanding it as a discrete notion with its own defining traits. In this work, Bertea specifically addresses the question: how should legal obligation be distinctively conceptualized? The conceptualization of legal obligation he defends in this work gradually emerges from a critical assessment of the theories of legal obligation that have been most influential in the contemporary legal-theoretical debate. Building on such critical analysis, Bertea's study purports (...) to offer a novel and unconventional conceptualization of legal obligation, which is characterized as a law-engendered intersubjective reason for carrying out certain courses of conduct.
