The "myside bias'' in evaluating arguments is an empirically well-confirmed phenomenon that consists of overweighting arguments that endorse one's beliefs or attack alternative beliefs while underweighting arguments that attack one's beliefs or defend alternative beliefs. This paper makes two contributions: First, it proposes a probabilistic model that adequately captures three salient features of myside bias in argument evaluation. Second, it provides a Bayesian justification of this model, thus showing that myside bias has a rational Bayesian explanation under certain conditions.

The model of self-referential truth presented in this paper, named Revision-theoretic supervaluation, aims to incorporate the philosophical insights of Gupta and Belnap’s Revision Theory of Truth into the formal framework of Kripkean fixed-point semantics. In Kripke-style theories the final set of grounded true sentences can be reached from below along a strictly increasing sequence of sets of grounded true sentences: in this sense, each stage of the construction can be viewed as an improvement on the previous ones. I want to (...) do something similar replacing the Kripkean sets of grounded true sentences with revision-theoretic sets of stable true sentences. This can be done by defining a monotone operator through a variant of van Fraassen’s supervaluation scheme which is simply based on ω-length iterations of the Tarskian operator. Clearly, all virtues of Kripke-style theories are preserved, and we can also prove that the resulting set of “grounded” true sentences shares some nice features with the sets of stable true sentences which are provided by the usual ways of formalising revision. What is expected is that a clearer philosophical content could be associated to this way of doing revision; hopefully, a content directly linked with the insights underlying finite revision processes.

What do we see when we look at someone's expression of fear? I argue that one of the things that we see is fear itself. I support this view by developing a theory of affect perception. The theory involves two claims. One is that expressions are patterns of facial changes that carry information about affects. The other is that the visual system extracts and processes such information. In particular, I argue that the visual system functions to detect the affects of (...) others when they are expressed in the face. I develop my theory by drawing on empirical data from psychology and brain science. Finally, I outline a theory of the semantics of affect perception. (shrink)

The my-side bias is a well-documented cognitive bias in the evaluation of arguments, in which reasoners in a discussion tend to overvalue arguments that confirm their prior beliefs, while undervaluing arguments that attack their prior beliefs. The first part of this paper develops and justifies a Bayesian model of myside bias at the level of individual reasoning. In the second part, this Bayesian model is implemented in an agent-based model of group discussion among myside-biased agents. The agent-based model is then (...) used to perform a number of experiments with the objective to study whether the myside bias hinders or enhances the ability of groups to collectively track the truth, that is, to reach the correct answer to a given binary issue. An analysis of the results suggests the following: First, whether the truth-tracking ability of groups is helped or hindered by myside bias crucially depends on how the strength of myside bias is differentially distributed across subgroups of discussants holding different beliefs. Second, small groups are more likely to track the truth than larger groups, suggesting that increasing group size has a detrimental effect on collective truth-tracking through discussion. (shrink)

In recent decades, the analysis of phraseology has made use of the exploration of large corpora as a source of quantitative information about language. This paper intends to present the main lines of work in progress based on this empirical approach to linguistic analysis. In particular, we focus our attention on some problems relating to the morpho-syntactic annotation of corpora. The CORIS/CODIS corpus of contemporary written Italian, developed at CILTA – University of Bologna (Rossini Favretti 2000; Rossini Favretti, Tamburini, De (...) Santis in press), is a synchronic 100-million-word corpus and is being lemmatised and annotated with part-of-speech (POS) tags, in order to increase the quantity of information and improve data retrieval procedures (Tamburini 2000). The aim of POS tagging is to assign each lexical unit to the appropriate word class. Usually the set of tags is pre-established by the linguist, who uses his/her competence to identify the different word classes. The very first experiments we made revealed how the traditional part-of-speech distinctions in Italian (generally based on morphological and semantic criteria) are often inadequate to represent the syntactic features of words in context. It is worth noting that the uncertainties in categorisation contained in Italian grammars and dictionaries reflect a growing difficulty as they move from fundamental linguistic classes, such as nouns and verbs, to more complex classes, such as adverbs, pronouns, prepositions and conjunctions. This latter class, that groups together elements traditionally used to express connections between sentences, appears inadequate when describing cohesive relations in Italian. This phenomenon actually seems to involve other elements traditionally assigned to different classes, such as adverbs, pronouns and interjections. Recent studies proposed the class of ‘connectives’, grouping all words that, apart from their traditional word class, have the function of connecting phrases and contributing to textual cohesion. From this point of view, conjunctions can be considered as part of phrasal connectives, that can in turn be included in the wider category of textual connectives. The aim of this study is to identify elements that can be included in the class of phrasal connectives, using quantitative methods. According to Shannon and Weaver’s (1949) observation that words are linked by dependent probabilities, corroborated by Halliday’s (1991) argument that the grammatical “system” (in Firth’s sense of the term) is essentially probabilistic, quantitative data are introduced in order to provide evidence of relative frequencies. Section 2 presents a description of word-class categorisation from the point of view of grammars and dictionaries arguing that the traditional category of conjunctions is inadequate for capturing the notion of phrasal connective. Section 3 examines the notion of ‘connective’ and suggests a truth-function interpretation of connective behaviour. Section 4 describes the quantitative methods proposed for analysing the distributional properties of lexical units, and section 5 comments on the results obtained by applying such methods drawing some provisional conclusions.

This paper is concerned with the issue of authenticity in Wittgenstein’s philosophy of psychology. In the manuscripts published as Letzte Schriften über die Philosophie der Psychologie – Das Innere und das Äußere, the German term Echtheit is mostly translated as ‘genuineness’. In these manuscripts, Wittgenstein frequently uses the term as referring to a feature of the expression of feeling and emotion: -/- […] I want to say that there is an original genuine expression of pain; that the expression of pain (...) therefore is not equally connected to the pain and to the pretence. (LW II, p. 55) -/- “This weeping gives the impression of being genuine” – so there is such a thing as genuine weeping. […]. (LW II, p. 87) -/- […] Genuineness and falseness are not the only essential characteristics of an expression of feeling. […]. (LW II, p. 90) -/- Wittgenstein contrasts the genuineness of the expressions with the possibility that the expressions are feigned. It seems to me that Wittgenstein is trying to discredit a specific version of the sceptical claim that we do not know other minds. I will refer to it as the sceptical innuendo. The sceptical innuendo says that every expression of feeling and emotion may be pretended. Wittgenstein’s approach to the issue reflects his later interest in the philosophy of psychology and, in particular, the problem of the ascription of psychological states (P-ascriptions) on the basis of someone else’s expression of feeling or emotion. Thus, the attempt to reject the sceptical innuendo is done mainly by means of conceptual and psychological arguments. Let’s look at this short dialogue between the sceptic and Wittgenstein. The former asks „How do you know that someone else is in a certain psychological state?“ Wittgenstein’s first reply is „I know that he is glad because I see him“. But the sceptic cannot be very happy with this reply. The sceptic’s next question is: „How do you know that he is really glad and he is not pretending?“ Wittgenstein’s response is not a direct refutation but is composed of a number of related reasons. These may be summed up in three arguments: -/- (i) A psychological argument from the very nature of the expressions. The expressions are meant to be natural symptoms of someone else’s psychological state (P-state). -/- (ii) A conceptual argument about the nature of pretence. It claims that pretence is a psychological property which is rightly ascribed when an observer has evidence for it. -/- (iii) A psychological argument from genuineness. It claims that we are committed to accept people’s expressions of feeling and emotion as genuine. (shrink)

Transfinite ordinal numbers enter mathematical practice mainly via the method of definition by transfinite recursion. Outside of axiomatic set theory, there is a significant mathematical tradition in works recasting proofs by transfinite recursion in other terms, mostly with the intention of eliminating the ordinals from the proofs. Leaving aside the different motivations which lead each specific case, we investigate the mathematics of this action of proof transforming and we address the problem of formalising the philosophical notion of elimination which characterises (...) this move.

Frege and Peano started in 1896 a debate where they contrasted the respective conceptions on the theory and practice of mathematical definitions. Which was (if any) the influence of the Frege-Peano debate on the conceptions by the two authors on the theme of defining in mathematics and which was the role played by this debate in the broader context of their scientific interaction?

The SIMS model claims that it is by means of an embodied simulation that we determine the meaning of an observed smile. This suggests that crucial interpretative work is done in the mapping that takes us from a perceived smile to the activation of one's own facial musculature. How is this mapping achieved? Might it depend upon a prior interpretation arrived at on the basis of perceptual and contextual information?

Happiness, like other basic emotions, has visual properties that create the conditions for happiness to be perceived in others. This is to say that happiness is perceivable. Its visual properties are to be identified with those facial expressions that are characteristic of happiness. Yet saying that something is perceivable does not suffice for us to conclude that it is perceived. We therefore need to show that happiness is perceived. Empirical evidence suggests that the visual system functions to perceive happiness as (...) well as other basic emotions. Experiences that can be had simply by virtue of how the perceptual system functions are known as observations. I will thus argue that visual experiences in which we become aware of others’ happiness are observations. This approach will provide the necessary conceptual framework to show that we have perceptual knowledge of others’ happiness. (shrink)

This paper is concerned with the answer Wittgenstein gives to a specific version of the sceptical problem of other minds. The sceptic claims that the expressions of feelings and emotions can always be pretended. Wittgenstein contrasts this idea with two arguments. The first argument shows that other-ascriptions of psychological states are justified by experience of the satisfaction of criteria. The second argument shows that if one accepts the conclusion of the first argument, then one is compelled to accept the idea (...) that pretence is justifiably ascribed on the same evidential basis, which justifies any other-ascriptions. The two arguments show that other-ascriptions of psychological states and pretence-ascriptions share the same evidential basis. This allows Wittgenstein to say that the sceptic’s appeal to the possibility of pretence implies a contradiction. (shrink)

Our objective in this paper is twofold: first, we intend to address the tenability of the enactivist middle way between realism and idealism, as it is proposed in The Embodied Mind. We do so by taking the enactivist conception of bringing forth a world literally in three conceptual levels: enaction, niche construction and social construction. Based on this proposal, we claim that enactivism is compatible with the idea of an independent reality without committing to the claim that organisms have cognitive (...) access to a world composed of properties specified prior to any cognitive activity. Our second goal is to show that our literal interpretation of bringing forth a world not only sustains the legitimacy of the middle way, but it also allows us to revive the conception of evolution as natural drift—which is perhaps the least examined aspect of the original enactivist theory and is central to the understanding of cognition in an enactive way. Natural drift focuses on how structural couplings between organism and environment trigger viable pathways of maintenance and reproduction, instead of selecting the most adapted trait to a pregiven environment. Thus, although enactivists typically do not explore the consequences of their views regarding evolutionary dynamics, we show how natural drift provides a suitable starting point. (shrink)

This article examines Karl Marx’s distributive justice principle “From each according to his ability, to each according to his needs,” contained in the Critique of the Gotha Program (1875). It argues that Marx advocates for “unequal equality,” since the end result of his principle is unequal contribution (due to the contributors’ different abilities) and unequal distribution (due to recipients’ different needs); that Marx’s principle avoids many pitfalls of contemporary desert theories; that while Marx is critical of formal, abstract right (Recht), (...) he maintains that right will be enhanced in the future communist society; that Marx’s attitude toward work is contradictory, since for him work is both “life’s prime want” and a hindrance to the intellectual and social flourishing possible only in leisure time; that the widespread interpretation of the communist society as one of abundance where all needs can be satisfied has scant textual basis; and that Marx’s principle continues to inspire theories of distributive justice and efforts to expand welfare and social services, and endeavors to establish a classless, cooperative society.

Review of the edited transcript of the 1978-1979 academic course given by political and legal philosopher Norberto Bobbio. The book examines the idea of political change in the works of Plato, Aristotle and the medieval thinkers, as well as the idea of revolution, which emerged in the 1600s together with the rival concept of political reform. The volume provides both a history and a conceptualisation of the notion of revolution; studies the attempts to understand the phenomenon and how the concept (...) of revolution influenced the views of history of Kant, Hegel and Marx; and develops a novel general theory of revolution. Bobbio seeks to narrow the scope of the concept of revolution, distinguishing it from phenomena such as rebellion and uprising; warns against using the term in a loose sense, such as in ‘industrial revolution’, ‘scientific revolution’ and ‘artistic revolution’; and provides his reasoned opinion on the crucial alternative between revolution and reform.

Currently, anomalous lived temporality is not included in the main diagnostic criteria or standard symptom checklists. In this article, we present the Transdiagnostic Assessment of Temporal Experience, a structured interview that can be used by researchers and clinicians without a comprehensive phenomenological background to explore abnormal time experiences in persons with abnormal mental conditions regardless of their diagnosis. When extensive data gathered by this scale are available, it will be possible to delineate well-defined anomalous lived temporality profiles for each psychopathological (...) disorder. This instrument may also prove useful for clinicians by providing a more refined assessment of relevant psychopathological symptoms and an in-depth understanding of the patient’s abnormal behaviour as related to specific types of time experience. In the first part of the article, we provide a brief overview of the phenomenological concept of temporality, including pre-phenomenal and phenomenal time, synthesis, conation and synchronization, and of abnormal time experiences in persons affected by psychopathological conditions. In the following part, we describe the basic structure of the interview that comprises seven categories corresponding to the abnormal features of lived temporality: anomalies of synchrony, of time structure, of implicit time flow, of explicit time flow, and anomalous experiences of the past, the present and the future. The paper also includes a section on administration and scoring of the TATE scale, the complete interview and a Likert table for quantifying the frequency, intensity and interference with daily life of the phenomena explored.

Williamson’s anti-luminosity argument has been thought to be in tension with the doctrine that we enjoy privileged epistemic access to our own mental states. In this paper, I will argue that the tension is only apparent. Friends of privileged access who accept the conclusion of the argument need not give up the claim that our beliefs about our own mental states are mostly or invariably right, nor the view that mental states are epistemically available to us in a way that (...) renders everything within our mind ‘open to view’ – arguably, two main pillars of their doctrine. What they need to reject is the idea that the mental is a realm whose ’determinacy’ or ’fineness of grain’ never escapes our appreciation. This idea – I will suggest – is not essential to privileged access and defenders of the doctrine should not be afraid to give it up. (shrink)

According to Leibniz’s infinite-analysis account of contingency, any derivative truth is contingent if and only if it does not admit of a finite proof. Following a tradition that goes back at least as far as Bertrand Russell, several interpreters have been tempted to explain this biconditional in terms of two other principles: first, that a derivative truth is contingent if and only if it contains infinitely complex concepts and, second, that a derivative truth contains infinitely complex concepts if and only (...) if it does not admit of a finite proof. A consequence of this interpretation is that Leibniz’s infinite-analysis account of contingency falls prey to Robert Adams’s Problem of Lucky Proof. I will argue that this interpretation is mistaken and that, once it is properly understood how the idea of an infinite proof fits into Leibniz’s circle of modal notions, the problem of lucky proof simply disappears.

Many philosophers have been attracted to the idea of using the logical form of a true sentence as a guide to the metaphysical grounds of the fact stated by that sentence. This paper looks at a particular instance of that idea: the widely accepted principle that disjunctions are grounded in their true disjuncts. I will argue that an unrestricted version of this principle has several problematic consequences and that it’s not obvious how the principle might be restricted in order to (...) avoid them. My suggestion is that, instead of trying to restrict the principle, we should distinguish between metaphysical and conceptual grounds and take the principle to apply exclusively to the latter. This suggestion, if correct, carries over to other prominent attempts at using logical form as a guide to ground. (shrink)

Ecological-enactive approaches to cognition aim to explain cognition in terms of the dynamic coupling between agent and environment. Accordingly, cognition of one’s immediate environment (which is sometimes labeled “basic” cognition) depends on enaction and the picking up of affordances. However, ecological-enactive views supposedly fail to account for what is sometimes called “higher” cognition, i.e., cognition about potentially absent targets, which therefore can only be explained by postulating representational content. This challenge levelled against ecological-enactive approaches highlights a putative explanatory gap between (...) basic and higher cognition. In this paper, we examine scientific cognition—a paradigmatic case of higher cognition—and argue that it shares fundamental features with basic cognition, for enaction and affordance selection are central to the scientific enterprise. Our argument focuses on modeling, and on how models promote scientific understanding. We base our argument on a non-representational account of scientific understanding and on the material engagement theory, for models are hereby conceived as material objects designed for scientific engagements. Having done so, we conclude that the explanatory gap is significantly less threatening to the ecological-enactive approach than it might appear. (shrink)

In order to meet the explanatory challenge levelled against non-representationalist views on cognition, radical enactivists claim that cognition about potentially absent targets involves the socioculturally scaffolded capacity to manipulate public symbols. At a developmental scale, this suggests that higher cognition gradually emerges as humans begin to master language use, which takes place around the third year of life. If, however, it is possible to show that pre-linguistic infants represent their surroundings, then the radical enactivists’ explanation for the emergence of higher (...) cognition is defeated. In this paper, I critically assess experiments designed to show that pre-linguistic infants inherit representational abilities. I begin by outlining these experiments in Sect. 2. In Sect. 3, I argue that these experiments only succeed in supporting widespread representationalism by committing a particular kind of circular reasoning, which I call conjunctivist reasoning due to its origins in the debates about the nature of perception. I conclude by developing two independent yet congruent enactivist lines of interpretation for the experiments discussed in 2. I explain the infants’ responses to atypical experimental conditions based on agent-environment codetermination and then I argue that surprise behavior can be explained in terms of embodied habits and unfulfilled anticipation.

Relativists make room for the possibility of “faultless disagreement” by positing the existence of subjective propositions, i.e. propositions true from some points of view and not others. We discuss whether the adoption of this position with respect to a certain domain of discourse is compatible with a realist attitude towards the matters arising in that domain. At first glance, the combination of relativism and realism leads to an unattractive metaphysical picture on which reality comprises incoherent facts. We will sketch the (...) contours of a realist-relativist position called “subjectivism”, which avoids this result by giving up the assumption that the points of view of different subjects are all metaphysically “on a par”.

There are two intuitions about time. The first is that there's something special about the present that objectively differentiates it from the past and the future. Call this intuition Specialness. The second is that the time at which we happen to live is just one among many other times, all of which are ‘on a par’ when it comes to their forming part of reality. Call this other intuition Egalitarianism. Tradition has it that the so-called ‘A-theories of time’ fare well (...) at addressing the first intuition, but rather badly when it comes to the second. The goal of this article is to offer advice to A-theorists about how to reconcile their view with Egalitarianism. (shrink)

This paper defends the view that one's own mental states are metaphysically privileged vis-à-vis the mental states of others, even if only subjectively so. This is an instance of a more general view called Subjectivism, according to which reality is only subjectively the way it is. After characterizing Subjectivism in analogy to two relatively familiar views in the metaphysics of modality and time, I compare the Subjectivist View of the Mental with Egocentric Presentism, a version of Subjectivism recently advocated by (...) Caspar Hare. I argue that the Subjectivist View of the Mental goes a considerable way towards solving certain long-standing philosophical puzzles having to do with the unity of consciousness, the contents of self-awareness and the intransmissibility of experiential knowledge through testimony.

Introduction to The Oxford Handbook of Phenomenological Psychopathology.

Solving the meta-problem of consciousness requires, among other things, explaining why we are so reluctant to endorse various forms of illusionism about the phenomenal. I will try to tackle this task in two steps. The first consists in clarifying how the concept of consciousness precludes the possibility of any distinction between 'appearance' and 'reality'. The second consists in spelling out our reasons for recognizing the existence of something that satisfies that concept.

The aims of my paper are to set out Aquinas’s arguments in favour of the thesis of God as Subsistent Being itself; set out the arguments against; and propose a fresh reading of that thesis that takes into account both Thomistic doctrine and the criticisms of it. In this way, I shall proceed as in a medieval quaestio, with arguments in favour, sed contra and respondeo.

It has been observed that, unlike other kinds of singular judgments, mental self-ascriptions are immune to error through misidentification: they may go wrong, but not as a result of mistaking someone else’s mental states for one’s own. Although recent years have witnessed increasing interest in this phenomenon, three basic questions about it remain without a satisfactory answer: what is exactly an error through misidentification? What does immunity to such errors consist in? And what does it take to explain the fact (...) that mental self-ascriptions exhibit this sort of immunity? The aim of this paper is to bring these questions into focus, propose some tentative answers and use them to show that one prominent attempt to explain the immunity to error through misidentification of mental self-ascriptions is unsuccessful.

We present an algebraic account of the Tongan kinship terminology (TKT) that provides an insightful journey into the fabric of Tongan culture. We begin with the ethnographic account of a social event. The account provides us with the activities of that day and the centrality of kin relations in the event, but it does not inform us of the conceptual system that the participants bring with them. Rather, it is a slice in time of an ongoing dynamic process that links (...) behavior with a conceptual system of kin relations and vice versa. To understand this interplay, we need an account of the underlying conceptual system that is being activated during the event. Thus, we introduce a formal, algebraically based account of TKT. This account brings to the fore the underlying logic of TKT and allows us to distinguish between features of the kinship system that arise from the logic of TKT as a generative structure and features that must have arisen through cultural intervention.

Kilimanjaro is an example of what some philosophers would call a ‘vague object’: it is only roughly 5895 m tall, its weight is not precise and its boundaries are fuzzy because some particles are neither determinately part of it nor determinately not part of it. It has been suggested that this vagueness arises as a result of semantic indecision: it is because we didn’t make up our mind what the expression “Kilimanjaro” applies to that we can truthfully say such things (...) as “It is indeterminate whether this particle is part of Kilimanjaro”. After reviewing some of the limitations of this approach, I will propose an alternative account, based on a new semantic relation—multiple reference—capable of holding in a one-many pattern between a term and several objects in the domain. I will explain how multiple reference works, what differentiates it from plural reference and how it might be used to accommodate at least some aspects of our ordinary discourse about vague objects.

In this paper, I will defend a communitarian perspective on the so-called “hinge propositions” (hinges, for short). Accordingly, I will argue that hinges play a normative role, in the sense that, among other things, they govern the mechanisms of social inclusion/exclusion. In particular, I will examine the so-called “religious hinges”; and I will argue that such hinges, being the product of mere indoctrination, are particularly effective in shaping boundaries among communities. Finally, with the help of Peter Munz's theory of altruism, (...) I will attempt to explain why religious hinges play the role they do. (shrink)

Based on Pritchard’s distinction (2012, 2016) between favoring and discriminating epistemic grounds, and on how those grounds bear on the elimination of skeptical possibilities, I present the dream argument as a moderate skeptical possibility that can be reasonably motivated. In order to block the dream argument skeptical conclusion, I present a version of phenomenological disjunctivism based on Noë’s actionist account of perceptual consciousness (2012). This suggests that perceptual knowledge is rationally grounded because it is a form of embodied achievement – (...) what I call embodied rationality –, which offers a way of dissolving the pseudo-problem of epistemic immodesty, namely, the seemingly counterintuitive thesis that one can acquire rationally grounded knowledge that one is not in a radical skeptical scenario.

Assuming a radical stance on embodied cognition, according to which the information ac- quired through basic cognitive processes is not contentful (Hutto and Myin, 2013), and as- suming that perception is a source of rationally grounded knowledge (Pritchard, 2012), a pluralistic account of perceptual knowledge is developed. The paper explains: (i) how the varieties of perceptual knowledge fall under the same broader category; (ii) how they are subject to the same kind of normative constraints; (iii) why there could not be (...) a conflict between the different varieties of perceptual knowledge; and (iv) why the traditional episte- mological inquiry is inclined to overestimate the role of propositional perceptual knowledge.

Giovanni Mion defends the idea that knowledge is context relative, but, in contrast to current versions of epistemic contextualism, on his view, knowledge is relative to contexts that are objective. Following Christopher Gauker’s conception of what a context is, Mion argues that knowledge is relative to the speakers’ conversational goals; and since the best way to achieve the goals of a conversation depends upon the way the world really is, it follows that participants in a conversation might be unaware (...) of the content of the context that truly governs their conversation. Finally, Mion uses objective contexts to explain why practical interests have epistemic significance. According to him, if we assume that the primary function of language is not to share thoughts, but to achieve practical goals, and, accordingly, that knowledge attributions play primarily an action-guiding role (as opposed to a mind-revealing role), then we are in a better position to understand why knowledge is not just a matter of theoretical factors, but it is also a matter of how much is at stake.

In this paper, I argue that knowledge is dimly luminous. That is: if a person knows that p, she knows how she knows that p. The argument depends on a safety-based account of propositional knowledge, which is salient in Williamson’s critique of the ‘KK’ principle. I combine that account with non-intellectualism about knowledge-how – according to which, if a person knows how to φ, then in nearly all (if not all) nearby possible worlds in which she φes in the same (...) way as in the actual world, she only φes successfully. Thus, the possession of first-order propositional knowledge implies secondorder practical knowledge, and this can be iterated. Because of the assumed nonintellectualism about know-how, dim luminosity does not imply bright luminosity about knowledge, which is expressed by the traditional KK principle. I conclude by considering some potential counterexamples to the view that knowledge is dimly luminous. (shrink)

Not unlike many contemporary philosophers, Leibniz admitted the existence of temporary truths, true propositions that have not always been or will not always be true. In contrast with contemporary philosophers, though, Leibniz conceived of truth in terms of analytic containment: on his view, the truth of a predicative sentence consists in the analytic containment of the concept expressed by the predicate in the concept expressed by the subject. Given that analytic relations among concepts are eternal and unchanging, the problem arises (...) of explaining how Leibniz reconciled one commitment with the other: how can truth be temporary, if concept-containment is not? This paper presents a new approach to this problem, based on the idea that a concept can be consistent at one time and inconsistent at another. It is argued that, given a proper understanding of what it is for a concept to be consistent, this idea is not as problematic as it may seem at first, and is in fact implied by Leibniz’s general views about propositions, in conjunction with the thesis that some propositions are only temporarily true.

Some philosophical considerations over Yann LeCun’s position paper “A Path Towards Autonomous Machine Intelligence”.

According to Russellian monism (RM), the quiddities which underlie the fundamental causal structure of the physical world are also responsible for the existence of phenomenal consciousness. This view has been argued to provide an attractive alternative to physicalism and dualism, but it is plagued by the so-called ‘combination problem’ – namely, the problem of explaining how the quiddities underlying the microphysical structure of a macroscopic conscious agent (e.g., a human being) combine together to constitute his or her phenomenal experiences. In (...) this paper, I will explore a type of monism that avoids the combination problem altogether. According to this view – which I shall call panquidditist monism – all causal roles, and not just the fundamental ones, stand in need of quiddities realizing them. Moreover, the quiddities that realize causal roles at one physical level should not in general be seen as grounded in, or otherwise derivative on, the quiddities that realize causal roles at lower levels. Crucial to the tenability of this view is a distinction between two varieties of grounding – one aiming to metaphysically explain the causal properties of various objects ‘from below’ (vertical grounding), the other aiming to metaphysically explaining them ‘from the inside’ (horizontal grounding). I will argue that, thanks to the distinction between vertical and horizontal grounds, panquidditist monism is well-placed to secure the advantages that RM promises – but, because of the combination problem, fails to deliver – vis-à-vis physicalism and dualism.

Philosophy of Mind is usualy seen as the theoretical field in which theories about the functioning of the mind are elaborated, to be afterwards empirically tested through Artificial Intelligence. But this empirical approach does not fit the human mind which is not simply a machine. It is therefore possible to see Philosophy of Mind as a necessary creation to empty AI of its philosophical charge.

The discussion and debates around Ethical AI cannot simply ignore the fact that ethics is not a self-standing discipline by is part of Philosophy and can only be approached as such.

The paper argues that it is the rise of Artificial Intelligence as a concrete possibility (the idea of a thinking machine) that favoured the growth of interest in Cognitive Science within the academic community. This puts the history and the definition of AI in a different light, as it can be seen and understood as "a continuation of Philosophy by other means" (Landi, 2020) and not merely as a technology or a sum of technologies.

In a recent article on Reid’s theory of single and double vision, James Van Cleve considers an argument against direct realism presented by Hume. Hume argues for the mind-dependent nature of the objects of our perception from the phenomenon of double vision. Reid does not address this particular argument, but Van Cleve considers possible answers Reid might have given to Hume. He finds fault with all these answers. Against Van Cleve, I argue that both appearances in double vision could be (...) considered visible figures of the object, and show how this solution might preserve Reid’s direct realism. However, this solution is not compatible with the single appearance of an object predicted by Reid’s theory of single and double vision. This consequence will appear evident once we consider the critique of Reid’s theory of single and double vision formulated by William Charles Wells (1757-1817). Wells argues that Reid’s theory is either incomplete or incompatible with other claims made by Reid. It is incomplete since it fails to specify the unique direction in which we the object in single vision; if it not incomplete and is compatible with the law of monocular direction given by Reid, then it is incompatible with Reid’s claim that we do not perceive immediately distance by sight.
