Why is there something rather than nothing? About this storied question we challenge the commonly accepted main assumption: the existence of something. Starting from Nothing only, we explain how our perceived reality emerges as an illusory self-referential interpretation of Nothing and build a framework to give precise definitions to fundamental concepts such as existence, reality, nothingness and somethingness. We then explore the consequences of this framework and we discover an explanation for the existence of laws of physics in our illusory (...) reality. By aiming to describe reality starting with Nothing, we provide the first instance of an assumption-less theory. (shrink)

We present an elementary system of axioms for the geometry of Minkowski spacetime. It strikes a balance between a simple and streamlined set of axioms and the attempt to give a direct formalization in first-order logic of the standard account of Minkowski spacetime in Maudlin and Malament. It is intended for future use in the formalization of physical theories in Minkowski spacetime. The choice of primitives is in the spirit of Tarski : a predicate of betwenness and a four place (...) predicate to compare the square of the relativistic intervals. Minkowski spacetime is described as a four dimensional ‘vector space’ that can be decomposed everywhere into a spacelike hyperplane—which obeys the Euclidean axioms in Tarski and Givant, 175–214 1999)—and an orthogonal timelike line. The length of other ‘vectors’ are calculated according to Pythagoras’ theorem. We conclude with a Representation Theorem relating models \ of our system \ that satisfy second order continuity to the mathematical structure \, called ‘Minkowski spacetime’ in physics textbooks.

This paper attempts a reconstruction of reason’s contribution to empirical truth in connection with Kant’s definition of truth as the agreement of cognition with its object. I argue that Kant’s treatment of truth in the Transcendental Analytic gets completed in the Appendix to the Transcendental Dialectic with an often neglected but compelling argument (what I shall call the Variety Argument). This argument postulates such a variety in the appearances as to undermine any attempt at formulating empirical truths. Crucially, I argue (...) that this variety does not depict an extreme-case scenario, but our own epistemic situation without reason. Reason completes Kant’s theory of truth by allowing the understanding (i.) to form empirical concepts and (ii.) approximate to empirical truth. (shrink)

Philosophers have debated at length the epistemological status of scientific thought experiments. I contend that the literature on this topic still lacks a common conceptual framework, a lacuna that produces radical disagreement among the participants in this debate. To remedy this problem, I suggest focusing on the distinction between the internal and the external validity of an experiment, which is also crucial for thought experiments. I then develop an account of both kinds of validity in the context of thought experiments. (...) I show that we can naturally conceptualise internal validity in terms of games of make-believe. Then, I argue that external validity is best defined as accurate representation of a target system. Finally, I turn back to the current debate on thought experiments and show that my diarchic account provides a general framework that can be shared by the competing philosophical views, as well as a fruitful guide for their reconciliation.

There are various forms of teleological thinking central to debates in the early modern and modern periods, debates in which David Hume (1711–1776) is a key figure. In the first section, we shall introduce three levels at which teleological considerations have been incorporated into philosophical accounts of man and nature, and sketch Hume’s criticisms of these approaches. In the second section, we turn to Hume’s non-teleological ‘science of man’. In the third section, we show how Hume has an account of (...) human flourishing that is not dependent on teleology. In the fourth section, we shall speculate as to the relation between Hume’s account of human nature and contemporary evolutionary accounts of morality and reasoning. (shrink)

What can we know? We know many things about the world around us: whether it is raining outside, the result of last night’s game, or how vaccines work. But we also want to know more. For example, we may want to know the ultimate origin of the universe, whether God exists, or whether there are such things as souls. Philosophers have long asked this type of questions — questions that concern a kind of knowledge that goes beyond our experience. A (...) wide range of answers (often contradicting each other) have been endlessly debated. Dissatisfied with this state of inquiry, Kant proposes a revolution in philosophy, which does not consist in devising new answers to these questions, but rather in analyzing our own capacity for knowledge. Such an analysis aims to shed light on the limits of our cognitive faculties and to reveal their true potential. In this article, we will see how Kant’s philosophy offers a revolutionary approach to our deep thirst for knowledge. (shrink)

Functionalism is the view that being x is to play the role of x. This paper defends a functionalist account of three-dimensional entities in the context of Wave Function Realism (WFR), that can explain in detail how we can recover three-dimensional entities out of the wavefunction. In particular, the essay advocates for a novel version of WFR in terms of a functional reductionist approach in the style of David Lewis. This account entails reduction of the upper entities to the bottom (...) ones, when the latter behave appropriately. As applied to WFR, it shows how the wavefunction can turn out to be identical to three-dimensional objects, provided certain conditions. The first major goal of the paper is thus to put forward an improved and more rigorous version of WFR, which dissolves several extant issues about the theory, and can serve as a starting point for future literature on the topic. Moreover, the second major goal of the article is to take WFR as a case study to demonstrate the pros of functional reductionism, especially in the form defended here, thereby helping to bring this view back in the philosophy of science debate. The positive upshots of this paper suggest a possible application of functional reductionism also to other contexts. (shrink)

Scientific models typically contain idealizations, or assumptions that are known not to be true. Philosophers have long questioned the nature of idealizations: Are they heuristic tools that will be abandoned? Or rather fictional representations of reality? And how can we reconcile them with realism about knowledge of nature? Immanuel Kant developed an account of scientific investigation that can inspire a new approach to the contemporary debate. Kant argued that scientific investigation is possible only if guided by ideal assumptions—what he calls (...) “regulative ideas”. These ideas are not true of objects of nature, and yet they are not heuristic tools or fictional represen- tations. They are necessary rules governing the construction and assessment of scientific explanations. In this paper, I suggest that some idealizations can be interpreted as having necessary regulative value and as being compatible with scientific realism. I first analyze the puzzle of the nature of idealization and present the main approaches to this topic in the literature. Second, I reconsider the puzzle vis-a-vis a restricted, Kantian definition of idealization and a novel characterization of the relation between idealization and truth. Finally, I discuss in detail an example of idealization (the Hardy-Weinberg equilibrium) along the suggested Kantian lines. (shrink)

I consider a problem for functional reductionism, based on the following tension. Say that b is functionally reduced to a. On the one hand, a and b turn out to be identical, and identity is a symmetric relation. On the other hand, functional reductionism implies that a and b are asymmetrically related: if b is functionally reduced to a, then a is not functionally reduced to b. Thus, we ask: how can a and b be asymmetrically related if they are (...) the same thing? I propose a solution to this tension, by distinguishing between ontological levels and levels of description.

Spontaneous collapse theories of quantum mechanics turn the usual Schrödinger equation into a stochastic dynamical law. In particular, in this paper, I will focus on the GRW theory. Two philosophical issues that can be raised about GRW concern (i) the ontology of the theory, in particular the nature of the wave function and its role within the theory, and (ii) the interpretation of the objective probabilities involved in the dynamics of the theory. During the last years, it has been claimed (...) that we can take advantage of dispositional properties in order to develop an ontology for GRW theory, and also in order to ground the objective probabilities which are postulated by it. However, in this paper, I will argue that the dispositional interpretations which have been discussed in the literature so far are either flawed or – at best – incomplete. If we want to endorse a dispositional interpretation of GRW theory we thus need an extended account that specifies the precise nature of those properties and which makes also clear how they can correctly ground all the probabilities postulated by the theory. Thus, after having introduced several different kinds of probabilistic dispositions, I will try to fill the gap in the literature by proposing a novel and complete dispositional account of GRW, based on what I call spontaneous weighted multi-track propensities. I claim that such an account can satisfy both of our desiderata. (shrink)

Lam and Esfeld have argued that, within Bohmian mechanics, the wave function can be interpreted as a physical structure instantiated by the fundamental particles posited by the theory. Further, to characterize the nature of this structure, they appeal to the framework of Ontic Structural Realism, thereby proposing a structuralist interpretation of Bohmian mechanics. However, I shall point out that OSR denotes a family of distinct views, each of which maintains a different account about the relation between structures and objects, and (...) entails a different kind of ontology. Thus, in this paper I will show how to articulate the structuralist approach to Bohmian Mechanics accordingly to the different standard versions of OSR, and I will evaluate these alternatives. Moreover, I will propose a novel and _sui generis_ kind of structuralist interpretation of Bohmian Mechanics, based on the framework of metaphysical coherentism. (shrink)

According to the most common interpretation of the simulation argument, we are very likely to live in an ancestor simulation. It is interesting to ask if some families of simulations are more likely than others inside the space of all simulations. We argue that a natural probability measure is given by computational complexity: easier simulations are more likely to be run. Remarkably this allows us to extract experimental predictions from the fact that we live in a simulation. For instance we (...) show that it is very likely that humanity will not achieve interstellar travel and that humanity will not meet other intelligent species in the universe, in turn explaining the Fermi's Paradox. On the opposite side, experimental falsification of any of these predictions would constitute evidence against our reality being a simulation. (shrink)

The first part of this paper finds Craver’s (2007) mutual manipulability theory (MM) of constitution inadequate, as it definitionally ties constitution to the feasibility of idealized experiments, which, however, are unrealizable in principle. As an alternative, the second part develops an abductive theory of constitution (NDC), which exploits the fact that phenomena and their constituents are unbreakably coupled via common causes. The best explanation for this common-cause coupling is the existence of an additional dependence relation, viz. constitution. Apart from adequately (...) capturing the essential characteristics of constitution missed by MM, NDC has important ramifications for constitutional discovery—most notably, that there is no experimentum crucis for constitution, not even under ideal discovery circumstances.

Despite recent essentialist approaches to Kant’s laws of nature, it is unclear whether Kant’s critical philosophy is compatible with core tenets of essentialism. In this paper, I first reconstruct Kant’s position by identifying the key metaphysical and epistemological features of his notion of ‘nature’ or ‘essence’. Two theses about natures can be found in the literature, namely that they are noumenal in character (_noumenal thesis_) and that they guide scientific investigation as regulative ideas of reason (_regulative thesis_). I argue that (...) Kant’s notion of nature does not entail the noumenal thesis and, based on his model of causal explanation, I propose a novel, _phenomenal thesis_, that allows for a better understanding of the function of natures as regulative ideas. In the last part of the paper, I show that Kant’s ‘essentialism’ is a genuine form of essentialism committed to _de re_ modality, although it differs in several respects from major contemporary essentialist accounts. I conclude by suggesting that Kant’s essentialism (if appropriately updated) can be relevant to the contemporary debate, which has so far been dominated by Humean and Aristotelian proposals.

Graham Priest's book In Contradiction is a bold defense of the existence of true contradictions. Although Priest's case is impressive, and many of his arguments are correct, his approach is not the only one allowing for true contradictions. As against Priest's, there is at least one contradictorialist approach which establishes a link between true contradictions and degrees of truth. All in all, such an alternative is more conservative, closer to mainstream analytical philosophy. The two approaches differ as regards the floodgate (...) problem. Priest espouses a confinement policy banning contradictions except in a few special domains, particularly those of pure semantics and set-theory , whereas the alternative approach admits two negations -- natural or weak negation and strong negation, the latter being classical; accordingly, the alternative approach prohibits any contradiction involving strong negation, thus providing a syntactic test of what contradictions have to be rejected.

Functional reductionism characterises inter-theoretic reduction as the recovery of the upper-level behaviour described by the reduced theory in terms of the lower-level reducing theory. For instance, finding a statistical mechanical realiser that plays the functional role of thermodynamic entropy allows for establishing a reductive link between thermodynamics and statistical mechanics. This view constitutes a unique approach to reduction that enjoys a number of positive features, but has received limited attention in the philosophy of science. -/- This paper aims to clarify (...) the meaning of functional reductionism in science, with a focus on physics, to define both its place with respect to other approaches to reduction and its connection to ontology. To do so, we develop and explore two alternative frameworks for functional reduction, called Syntactic Functional Reductionism and Semantic Functional Reductionism. They represent two different possible stances on the view that expand and improve the basic functional reductionist approach along different lines, and make clear how the approach works in practice. The former elaborates on David Lewis’ account, is connected with the syntactic view of theories, is committed to a logical characterisation of functional roles, and is embedded within Nagelian reductionism. The latter adopts a semantic view of theories, spells out functional roles mainly in terms of mathematical roles within the models of theories, and is expressed in terms of the related structuralist approach to reduction. The development of these frameworks has the final goal of advancing functional reductionism, to make it a fully-fledged alternative account for reduction in science. (shrink)

It has been argued that Humean Supervenience is threatened by the existence of quantum entanglement relations. The most conservative strategy for defending HS is to add the problematic entanglement relations to the supervenience basis, alongside spatiotemporal relations. In this paper, I’m going to argue against this strategy by showing how certain particular cases of tripartite entanglement states – i.e. GHZ states – posit some crucial problems for this amended version of HS. Moreover, I will show that the principle of free (...) recombination – which is strictly linked to HS – is severely undermined if we add entanglement relations to the supervenience basis. I conclude that the conservative move is very unappealing, and therefore the defender of HS should pursue other, more controversial, strategies. (shrink)

In this paper, I offer a systematic account of Kant’s view on ‘phenomenal substance’. Several studies have recently analyzed Kant’s notion of substance. However, I submit that more needs to be said about how this notion is reconceptualized within the critical framework to vindicate a genuine and legitimate sense of substance in the phenomenal realm. More specifically, I show that Kant’s transcendental idealism does not commit him to a rejection of substantiality in phenomena. Rather, Kant isolates a general notion of (...) substance (as ultimate subject) and argues that (i) the relationality of phenomena is compatible with this notion; and that (ii) matter and all its parts are the ultimate subjects of everything existing in space (as what is independently movable in space). I suggest that vindicating a genuine and legitimate notion of phenomenal substance has far-ranging consequences for the interpretation of Kant’s empirical realism. (shrink)

In this paper, we embark on the complicated discussion about the nature of vice in Virtue Ethics through a twofold approach: first, by taking seriously the claim that virtues (and certain flavours of vices) are genuinely dispositional features possessed by agents, and secondly, by employing a pluralistic attitude borrowed from Battaly’s pluralism (2008). Through these lenses, we identify three varieties of viciousness: incontinence, indifference, and malevolence. The upshot is that the notion of vice is not as categorically homogeneous as that (...) of virtue: some states of viciousness consist in interference of present virtuous dispositions, or mimicking of absent vicious ones, whereas others can be considered genuine dispositions themselves. Furthermore, this set-up can provide an interesting, albeit highly idealized story as to how, through the interference in one’s environment, one gets acquainted with vice in various degrees. Finally, this approach can be illuminating vis-à-vis Virtue Ethics in general; e.g. we can employ it to discuss more productively Johnston’s (2003) objection to Hursthouse’s (1999) account of moral conduct.

Since Saul Kripke’s influential work in the 1970s, the revisionary approach to semantic paradox—the idea that semantic paradoxes must be solved by weakening classical logic—has been increasingly popular. In this paper, we present a new revenge argument to the effect that the main revisionary approaches breed new paradoxes that they are unable to block.

In his Bibliographia politica Naudé reviews in about one hundred pages authors and works that have dealt with politics, from the Antiquity to the first decades of the Seventeenth Century. In few enlightened pages on the ordinary and extraordinary administration of the State, Naudé elaborates his own idea of Reason of State, including the use of an extraordinary administration in the name of the public benefit. We can find a continuity between his Bibliographia politica and his Considérations politiques sur les (...) coups d’Estat. In both his political works Naudé gives to the category of wisdom, derived from Aristotle, a new practical and political value, which goes back to authors such as Machiavelli or Cardano, Lipsius or Charron. Naudé’s political wisdom uses dissimulation and any form of justice, also against common law, to act in extraordinary administration of the State or to carry out “coups d’État.”. (shrink)

In the Critique of Pure Reason, Kant often remarks that phenomena consist only in relations. This is a highly puzzling thesis that is not easily reconcilable with the explanation of natural processes. More specifically, it is not clear whether and how a network of mere relations (such as ‘being higher than’, ‘being next to’, etc.) can give rise to genuine changes in nature. I call this the problem of global relationality. In this paper, I suggest a solution to this problem (...) by showing that Kant’s specific sense of relationality is ultimately grounded in the spatiality of phenomena and differs from the one usually assumed in the contemporary debate. I argue that a subset of empirical properties can be regarded as ‘comparatively intrinsic’ since they preserve a genuine sense of intrinsicness while being fully relational in space. As a result, real changes can take place in the phenomenal realm if they concern comparatively intrinsic properties of empirical objects. (shrink)

In this essay, I offer a vindication of pride. I start by presenting the Christian condemnation of pride as the cardinal sin. I subsequently examine Mandeville’s line of argument whereby pride is beneficial to society, although remaining a vice for the individual. Finally, I focus on, and endorse, the analysis of pride formulated by Hume, for whom pride qualifies instead as a virtue. This is because pride not only contributes to making society flourish but also stabilizes the virtuous agent by (...) creating a virtuous circle between our desire for self-appraisal and our aspiration to act morally. I conclude by underscoring the (virtuous) connection between pride and modesty, concomitantly arguing that humility should be discarded as vicious. (shrink)

In this paper, I examine Eugenio Lecaldano’s way of tackling the issue of the meaning of life. I highlight the dependence of his individualistic approach on the specific character of the person who inquires into the meaning of life. I also sketch a weaker way of understanding the meaning of life as an attempt to provide reasons which are valid from the standpoint of the present, and which will make us continue living.

This paper aims to show how Kant’s account of theoretical reason can inform the contemporary debate over unity and pluralism of science. Although the unity of science thesis has been severely criticized in recent decades, I argue that pluralism as the sole epistemic principle guiding science is both too strong and too weak a principle. It is too strong because it does not account for the process of theory unification in science. It is too weak because it does not answer (...) the question of how science ought to be done. I then look at a promising ‘perspectival’ (i.e., epistemically situated) approach to the problem Kant presents in the Appendix to the Transcendental Dialectic. I argue that the logical principles of systematicity (homogeneity, specification, continuity) form a ‘perspectival space’ within which scientists can pursue both unity and disunity of cognition. Finally, I suggest that the existing conflict between pluralism and unity ultimately resides in a metaphysical characterization of unity that does not correctly capture its epistemic significance in science. Looking at Kant’s ‘perspectivism’ not only allows us to resolve this apparent antinomy, but also to rethink unity and pluralism as mutually inclusive regulative principles. (shrink)

What role does habit formation play in the development of sport skills? We argue that motor habits are both necessary for and constitutive of sensorimotor skill as they support an automatic, yet inherently intelligent and flexible, form of action control. Intellectualists about skills generally assume that what makes action intelligent and flexible is its intentionality, and that intentionality must be necessarily cognitive in nature to allow for both deliberation and explicit goal-representation. Against Intellectualism we argue that the habitual behaviours that (...) compose skilful action are accompanied by their specific, non-cognitive form of intentionality: this is motor intentionality, which is purposive and adaptive while involving no explicit deliberation or goal representation. Our account of habit based on Motor Intentionality explains why the formation of motor habits can sometimes act as the sole basis of skilful acquisition: Motor Intentionality is inherently purposeful because it is an embodied source of sensorimotor anticipation, pre-reflective motivation, and pragmatic know-how. Skill development through exercise always builds on a motor intentional component even when it is guided by Deliberate Practice to the point that, pace Intellectualism, Deliberate Practice is disclosed, not constrained, by habit formation. As suggested by the fact that repetitive exercises can play a major role in the development of flexible and intelligent sport skills, automatism is not a drawback for strategic control and improvisation but rather their pragmatic foundation.

Can an identity be the proper subject of an explanation? A popular stance, albeit not one often argued for, gives a negative answer to this question. Building from a contentious passage from Jaegwon Kim in this direction, we reconstruct an argument to the conclusion that identities, to the extent in which they are necessary, cannot be explained. The notion of contrastive explanation, characterized as difference-seeking, will be crucial for this argument; however, we will eventually find the argument to be unsatisfactory. (...) On the contrary, the discussion provides enough resource to sketch a very simple framework for a non-causal contrastive explanation of identities. Many instances will be provided, with different varieties of explanans, ultimately suggesting that certain entailment or biconditional principles involving identities (first and foremost, so-called two-level identity criteria) may indeed be taken to have an inherent explanatory value.

The aim of this paper is to theorize insurgent political action on the basis of Jean-Paul Sartre’s Critique of Dialectical Reason. It reconstructs a Sartrean model of insurgency that prioritizes an insurgent group’s capacity for situated inventions. It argues that, similar to Fanon, Sartre theorized that groups that struggle against oppression and exploitation constantly invent novel conditions that steer society in unforeseeable directions. However, these inventions of insurgent action are never absolutely contingent but always take place in concrete situations which (...) never cease to condition them. This paper analyses two concrete factors which condition the inventions of insurgent action: the seriality from which the group arises and to which it always threatens to return, and the actions of hostile groups. Taken together, this paper claims that Sartre provides a coherent and innovative account of insurgent political action. (shrink)

Starting from the assumption that aesthetic is an anthropological fact which like language or symbolic thought belongs to the behavioral, cognitive and social register of our species, the article aims to clarify the uses of the category of aesthetic in the human sciences (social anthropology, cognitive psychology, evolutionary anthropology).

The article analyses libertine themes and authors of 17th century in articles, critical notes and reviews of three major Italian journals of the 20th century – Rivista di filosofia, Giornale critico della filosofia italiana and Rivista critica di storia della filosofia (since 1984 titled Rivista di storia della filosofia). The category of ‘libertinism’ refers to various disciplinary fields: philosophy, politics, literature, modern history or religious history. This ambiguity influences the analyses of libertinism in the Italian historic-philosophical debate. The last two (...) decades of the 20th century show a renewed interest of the three journals on libertine themes and on the relationship between libertinism and philosophy. Research on libertine thought focuses mainly on French libertinism (i.e. libertinage érudit) and on the philosophical clandestine literature: the journals discuss or review clandestine texts, as the Theophrastus redivivus (1659), whose critical edition was published in Italy in 1981–1982.

Recent epidemiological reports of associations between socioeconomic status and epigenetic markers that predict vulnerability to diseases are bringing to light substantial biological effects of social inequalities. Here, we start the discussion of the moral consequences of these findings. We firstly highlight their explanatory importance in the context of the research program on the Developmental Origins of Health and Disease (DOHaD) and the social determinants of health. In the second section, we review some theories of the moral status of health inequalities. (...) Rather than a complete outline of the debate, we single out those theories that rest on the principle of equality of opportunity and analyze the consequences of DOHaD and epigenetics for these particular conceptions of justice. We argue that DOHaD and epigenetics reshape the conceptual distinction between natural and acquired traits on which these theories rely and might provide important policy tools to tackle unjust distributions of health.

Three accounts of effective realism (ER) have been advanced to solve three problems for scientific realism: Fraser and Vickers (forthcoming) develop a version of ER about non-relativistic quantum mechanics that they argue is compatible with all the main realist versions (‘interpretations’) of quantum mechanics avoiding the problem of underdetermination among them; Williams (2019) and Fraser (2020b) propose ER about quantum field theory as a response to the problems facing realist interpretations; Robertson and Wilson (forthcoming) propose ER to deal with the (...) dubious ontological status of the entities belonging to superseded theories. This paper argues for the unification of these proposals based on realism about modal structure and the idea of scale relativity of ontology developed by ontic structural realists. This solves problems some or all the accounts of ER face, especially that of making explicit in what way they are realist. Furthermore, we respond to a recent critique that has been raised against the ontic structural realist account of quantum mechanics that we employ. (shrink)

Il presente saggio breve si prefigge di affrontare con sguardo sociologico il binomio solidità/liquidità.

Fürwahrhalten, or “holding-to-be-true”, is one of the most controversial concepts in Kant’s epistemology. Rarely mentioned in Kant’s edited works – where it is often used to describe moral faith – Fürwahrhalten has attracted the interest of Kant scholars only in recent years. The essay aims to shed light on some of the main issues that the notion of holding-to-be-true still rises, especially those concerning its origin and its theoretical function in the critical system. The book retraces the stages of Kant’s (...) reflection on this theme, starting from the precritical discussion with the main representatives of the German Enlightenment (Wolff, Knutzen, Baumgarten, Meier, and Crusius) to the definitive formulation of Fürwahrhalten after the publication of the Critique of Pure Reason. The analysis of Kant’s logical corpus has shown that, far from being a marginal concept of critical epistemology, Fürwahrhalten is the core of a systematic theory of certainty, that Kant develops in accordance with his doctrine of modality. This theory represents the arrival point of a long and troubled reflection, that led Kant to deeply rethink most of the traditional themes of eighteenth-century logic. (shrink)

Wittgenstein si presenta, nel panorama filosofico novecentesco, come uno dei filosofi più originali. Nella fase finale della sua vita, giunge a criticare la concezione tradizionale del rapporto tra mente e significato, per la quale a garanzia della relazione di significazione basterebbe l'accesso che ciascun individuo ha ai propri contenuti mentali, riscontrando quindi il fondamento del significato nell'interiorità soggettiva. Wittgenstein, invece, avanza una prospettiva che pone un "gioco linguistico" con delle regole ben precise come condizione di giudizio del significato di un'espressione (...) linguistica, regole che sono oggettive e condivise, non private, e che determinano precise funzioni del linguaggio e della conoscenza. Lo studio di Wittgenstein trova motivazione se consideriamo che, attraverso i secoli, la filosofia ha sviluppato un suo proprio linguaggio che si è costantemente reinventato e specializzato, a seconda dello sviluppo storico e degli eventi che lo hanno caratterizzato; periodicamente, quando in maniera velata, quando esplicita, essa ha cercato di imitare il linguaggio scientifico, con l'aspirazione di un maggiore rigore espositivo e concettuale.

Beall and Murzi :143–165, 2013) introduce an object-linguistic predicate for naïve validity, governed by intuitive principles that are inconsistent with the classical structural rules. As a consequence, they suggest that revisionary approaches to semantic paradox must be substructural. In response to Beall and Murzi, Field :1–19, 2017) has argued that naïve validity principles do not admit of a coherent reading and that, for this reason, a non-classical solution to the semantic paradoxes need not be substructural. The aim of this paper (...) is to respond to Field’s objections and to point to a coherent notion of validity which underwrites a coherent reading of Beall and Murzi’s principles: grounded validity. The notion, first introduced by Nicolai and Rossi, is a generalisation of Kripke’s notion of grounded truth, and yields an irreflexive logic. While we do not advocate the adoption of a substructural logic, we take the notion of naïve validity to be a legitimate semantic notion that points to genuine expressive limitations of fully structural revisionary approaches.

Why did Locke exclude Catholics and atheists from toleration? Not, I contend, because he was trapped by his context, but because his prudential approach and practica ljudgments led him to traditiona ltexts.

I then describe important continuities betweenc onventional English understandings of the relationship between state and religion and Locke's writings on toleration, discuss Locke's conception of rights, and illustrate his use of prudential exceptions (...) and distinctions. I conclude by arguing that Locke's problems are relevant to assessingc ontemporary liberal discussions of tolerationa nd the separation of state and religion that lean heavily on practical justifications.

It is hard to believe that colors, sounds, tastes and feelings, the essential ingredients of the world as we know it, never existed in the universe until complex nervous systems appeared. This paper explores the idea that phenomenal experiences made of sensible qualities such as colors and sounds exist physically as the “clothing” of matter and are real public appearances that may be experienced by any locally situated subject, shared by multiple such subjects, or may even exist unperceived. In this (...) panqualityist worldview our awareness goes right up against the physical world that we can directly perceive. Material objects really have colors that are ubiquitous and existed in nature before brains evolved. The evolution of the brain did not create new physics, but employed the same ubiquitous simple physical laws that generate colors in external objects to generate colors internally. I theorize that there are different “matter to qualia” bridging laws for each sense modality and speculate as to what they may look like. (shrink)

Dominus Vobiscum is undoubtedly one of Peter Damian’s most original works, and has experienced a renewed interest thanks to the re-emergence of the ecclesiology of communion around Vatican II, but in-depth studies of the work as a whole are missing and its sources seem quite limited. In this analysis of the text and its argumentative structure, the conceptual development is built on the dialectic of contrasts, starting from the binomial of “solitudo pluralis” and “multitudo singularis”, typical of the hermit. The (...) theme is unfolded in its pneumatological, Christological and ecclesiological aspects. A formal analysis seems to demonstrate that the theses presented by Peter Damian are mainly the result of the power of rhetoric, which he undoubtedly mastered. (shrink)

This paper develops a trivalent semantics for the truth conditions and the probability of the natural language indicative conditional. Our framework rests on trivalent truth conditions first proposed by Cooper (1968) and Belnap (1973) and it yields two logics of conditional reasoning: (i) a logic C of certainty-preserving inference; and (ii) a logic U for uncertain reasoning that preserves the probability of the premises. We show systematic correspondences between trivalent and probabilistic representations of inferences in either framework, and we use (...) the distinction between the two systems to cast light on the validity of inferences such as Modus Ponens, Or-To-If, and Conditional Excluded Middle. Specifically, the conditional behaves monotonically in C, but non-monotonically in U; Modus Ponens is valid in C, but valid in U only for non-nested conditionals. The result is a unified account of the semantics and epistemology of indicative conditionals that can be fruitfully applied to analyzing the validity of conditional inferences. (shrink)

This paper promotes an evolutionary emergent panpsychism that has several advantages over the popular constitutive type. It recognizes layers in nature and theorizes an intelligible stepwise evolution of consciousness from the micro to the macro level. It is consistent with mental causal efficacy at the higher animal level and not just base particle levels. Finally it can explain to some degree the sense we have of a diachronic self persisting in time.
