Philosophers have suggested that, in order to understand the particular visual state we are in during picture perception, we should focus on experimental results from vision neuroscience—in particular, on the most rigorous account of the functioning of the visual system that we have from vision neuroscience, namely, the ‘Two Visual Systems Model’. According to the initial version of this model, our visual system can be dissociated, from an anatomo-functional point of view, into two streams: a ventral stream subserving visual recognition, (...) and a dorsal stream subserving the visual guidance of action. Following this model, philosophers have suggested that, since the two streams have different functions, they represent different properties of a picture. However, the original view proposed by the ‘Two Visual Systems Model’ about the presence of a strong anatomo-functional dissociation between the two streams has recently been questioned on both philosophical and experimental grounds. Indeed, the analysis of several new pieces of evidence seems to suggest that many visual representations in our visual system, related to different tasks, are the result of a deep functional interaction between the streams. In the light of the renewed status of the ‘Two Visual Systems Model’, also our best philosophical model of picture perception should be renewed, in order to take into account a view of the process of picture perception informed by the new evidence about such interaction. Despite this, no account fulfilling this role has been offered yet. The aim of the present paper is precisely to offer such an account. It does this by suggesting that the peculiar visual state we are in during picture perception is subserved by interstream interaction. This proposal allows us to rely on a rigorous philosophical account of picture perception that is, however, also based on the most recent results from neuroscience. Unless the explanation offered in this paper is endorsed, all the recent evidence from vision neuroscience will remain unexplained under our best empirically informed philosophical theory of picture perception.

Intellectualists suggest that practical knowledge, or ‘knowing- how’, can be reduced to propositional knowledge, or ‘knowing-that’. Anti-intellectualists, on the contrary, suggest, following the original insights by Ryle, that such a reduction is not possible. Rejection of intellectualism can be proposed either by offering purely philosophical analytical arguments, or by recruiting empirical evidence from cognitive science about the nature of the mental representations involved in these two forms of knowledge. In this paper, I couple these two strategies in order to analyze (...) some crucial reasons for which intellectualism seems not to be the best theory we have to correctly understand and describe practical knowledge. In particular, I will start from a specific philosophical account against intellectualism offered by Dickie :737–745, 2012), and suggest that it can be supported by current experimental results coming from motor neuroscience. The claim of the paper is that there is at least one kind of practical knowledge, which I call motor knowledge, and which is at the basis of the performance of skilled action, which cannot be reduced to propositional knowledge.

In this article, we propose a new account concerning the interlock between intentions and motor representations (henceforth: MRs), showing that the interface problem is not as deep as previously proposed. Before discussing our view, in the first section we report the ideas developed in the literature by those who have tried to solve this puzzle before us. The article proceeds as follows. In Sections 2 and 3, we address the views by Butterfill and Sinigaglia, and Mylopoulos and Pacherie, respectively, and (...) argue that both solutions entail a translation between representational formats, which both accounts aim to avoid. In Section 4, we present our brand‐new claim, according to which intentions and MRs partially share the same motor format, inasmuch as executable action concepts are naturally represented in the agent's motor system together with the action's outcomes. Indeed, since intentions are constituted by executable action concepts and since there is evidence that action concepts are represented (and, thus, built) in the same motor format as action outcomes, the interlock between intentions and MRs no longer constitutes a problem. Then, in Section 5, we report empirical evidence in support of our claim, and before concluding, in Section 6 we briefly clarify our relations with two very recent accounts that criticized the proposals by Mylopoulos and Pacherie and Butterfill and Sinigaglia: Shepherd's and Burnston's. Finally, in Section 7, we offer some remarks about the philosophical idea defended here. The basic insight is that interface without translation is possible because action concepts are such stuff as MRs are made on. (shrink)

The most important question concerning picture perception is: what perceptual state are we in when we see an object in a picture? In order to answer this question, philosophers have used the results of the two visual systems model, according to which our visual system can be divided into two streams, a ventral stream for object recognition, allowing one to perceive from an allocentric frame of reference, and a dorsal stream for visually guided motor interaction, thus allowing one to perceive (...) from an egocentric frame of reference. Following this model, philosophers denied that we can be in a dorsal perceptual state when perceiving a depicted object. This is because a depicted object is not physically graspable or manipulable and, in turn, it cannot be egocentrically localized, as a normal object, by the dorsal stream. Thus, the impossibility of manipulating depicted objects and of localizing them from an egocentric frame of reference has led some people to be sceptical about the possibility of a representation of action properties in the perception of objects in pictures, which pertains to the dorsal visual system. The aim of the present paper is to show that it is possible for the depicted object to be represented by dorsal perception. That means that we can ascribe action properties to depicted objects as well, even if depicted objects cannot be egocentrically localized—at least, not as much as normal objects can. (shrink)

This book presents a systematic interpretation of Charles S. Peirce’s work based on a Kantian understanding of his teleological account of thought and inquiry. Departing from readings that contrast Peirce’s treatment of purpose, end, and teleology with his early studies of Kant, Gabriele Gava instead argues that focusing on Peirce’s purposefulness as a necessary regulative condition for inquiry and semiotic processes allows for a transcendental interpretation of Peirce’s philosophical project. The author advances this interpretation through presenting original views on (...) aspects of Peirce’s thought, including: a detailed analysis of Peirce’s ‘methodeutic’ and ‘speculative rhetoric,’ as well as his ‘critical common-sensism’; a comparison between Peirce’s and James’ pragmatisms in view of the account of purposefulness Gava puts forth; and an examination of the logical relationships that order Peirce’s architectonic classification of the sciences.

In this paper, I distinguish between two varieties of actualism—hardcore actualism and softcore actualism—and I critically discuss Ross Cameron’s recent arguments for preferring a softcore actualist account of the truthmakers for modal truths over hardcore actualist ones. In the process, I offer some arguments for preferring the hardcore actualist account of modal truthmakers over the softcore actualist one.

This discussion of pride, shame, and guilt centers on the beliefs involved in the experience of any of these emotions. Through a detailed study, the author demonstrates how these beliefs are alike--in that they are all directed towards the self--and how they differ. The experience of these three emotions are illustrated by examples taken from English literature. These concrete cases supply a context for study and indicate the complexity of the situations in which these emotions usually occur.

My two daughters would love to go tobogganing down the hill by themselves, but they are just toddlers and I am an apprehensive parent, so, before letting them do so, I want to ensure that the toboggan won’t go too fast. But how fast will it go? One way to try to answer this question would be to tackle the problem head on. Since my daughters and their toboggan are initially at rest, according to classical mechanics, their final velocity will (...) be determined by the forces they will be subjected to between the moment the toboggan will be released at the top of the hill and the moment it will reach its highest speed. The problem is that, throughout their downhill journey, my daughters and the toboggan will be subjected to an incredibly large number of forces—from the gravitational pull of any massive object in the universe to the weight of the snowflake that is sitting on the tip of one of my youngest daughter’s hairs—so that any attempt to apply the theory directly to the real-world system in all its complexity seems to be doomed to failure.

In a recent paper, ‘Peripersonal perception in action’ (Synthese, 2018), Frédérique de Vignemont tackles the problem of defining what is peculiar to the visual perception of objects falling within the peripersonal space of the observer, i.e. the space immediately surrounding the body, and which is commonly described as the space in which action takes place. In this paper, I first discuss the proposal offered by de Vignemont about what characterizes peripersonal perception. Then, I suggest an extension of this account that (...) offers a meticulous description of the nature of the Content of Peripersonal Visual Experience - a topic never explicitly considered in the philosophical literature on vision - by discussing some peculiar features of it that, as recognized also by de Vignemont’s account, still need to be explained. In particular, I offer a philosophical examination of the specificity of peripersonal visual experience, in relation to its phenomenological dimension, its optical mechanisms and its neurophysiological underpinnings, in the light of our best theories from vision science, and in comparison to the visual experience of other visual spaces.

In Schwichtenberg, Schwichtenberg fine-tuned Tait’s technique so as to provide a simplified version of Gentzen’s original cut-elimination procedure for first-order classical logic. In this note we show that, limited to the case of classical propositional logic, the Tait–Schwichtenberg algorithm allows for a further simplification. The procedure offered here is implemented on Kleene’s sequent system G4. The specific formulation of the logical rules for G4 allows us to provide bounds on the height of cut-free proofs just in terms of the logical (...) complexity of their end-sequent. (shrink)

Mereological nihilism is the thesis that there are no composite objects—i.e. objects with proper material parts. One of the main advantages of mereological nihilism is that it allows its supporters to avoid a number of notorious philosophical puzzles. However, it seems to offer this advantage only at the expense of certain widespread and deeply entrenched beliefs. In particular, it is usually assumed that mereological nihilism entails eliminativism about ordinary objects—i.e. the counterintuitive thesis that there are no such things as tables, (...) apples, cats, and the like. In this paper, I argue that this assumption is false—mereological nihilists do not need to be eliminativists about tables, apples, or cats. Non-eliminativist nihilists claim that all it takes for there to be a cat is that there are simples arranged cat-wise. More specifically, non-eliminative nihilists argue that expressions such as ‘the cat’ in sentences such as ‘The cat is on the mat’ do not refer to composite objects but only to simples arranged cat-wise and compare this metaphysical discovery to the scientific discovery that ‘water’ refers to dihydrogen oxide. Non-eliminative nihilism, I argue, is not only a coherent position, but it is preferable to its more popular, eliminativist counterpart, as it enjoys the key benefits of nihilism without incurring the prohibitive costs of eliminativism. Moreover, unlike conciliatory strategies adopted by eliminative nihilists, non-eliminative nihilism allow its supporters to account not only for how we can assert something true by saying ‘The cat is on the mat’ but also for how we can believe something true by believing that the cat is on the mat.

This paper explores the debate between those philosophers who take (fundamental, perfectly natural) properties to be pure powers and those who take them to be powerful qualities. I first consider two challenges for the view that properties are powerful qualities, which I call, respectively, ‘the clarification challenge’ and ‘the explanatory challenge’. I then examine a number of arguments that aim to show that properties cannot be pure powers and find them all wanting. Finally, I sketch what I take to be (...) the most promising argument against pure powers and for powerful qualities. (shrink)

Both in his pre-critical writings and in his critical works, Kant criticizes the Wolffian tradition for its use of the mathematical method in philosophy. The chapter argues that the apparent unambiguousness of this opposition between Kant and Wolff notwithstanding, the problem of ascertaining the relationship between Kant’s and Wolff’s methods in philosophy cannot be dismissed so quickly. Only a close consideration of Kant’s different remarks on Wolff’s approach and a comparison of the methods that Wolff and Kant actually used in (...) philosophy can allow us to determine when Kant’s criticisms are justified and where the differences in their methodological proposals for philosophy actually lie. We see that Kant’s account of philosophical method in fact has some elements in common with the Wolffian paradigm, even though there are also relevant differences. (shrink)

Picture perception and ordinary perception of real objects differ in several respects. Two of their main differences are: Depicted objects are not perceived as present and We cannot perceive significant spatial shifts as we move with respect to them. Some special illusory pictures escape these visual effects obtained in usual picture perception. First, trompe l'oeil paintings violate : the depicted object looks, even momentarily, like a present object. Second, anamorphic paintings violate : they lead to appreciate spatial shifts resulting from (...) movement. However, anamorphic paintings do not violate : they are still perceived as clearly pictorial, that is, nonpresent. What about the relation between trompe l'oeil paintings and? Do trompe l'oeils allow us to perceive spatial shifts? Nobody has ever focused on this aspect of trompe l'oeil perception. I offer the first speculation about this question. I suggest that, if we follow our most recent theories in philosophy and vision science about the mechanisms of picture perception, then, the only plausible answer, in line with phenomenological intuitions, is that, differently from nonillusory, usual picture perception, and similarly to ordinary perception, trompe l'oeil perception does allow us to perceive spatial shifts resulting from movement. I also discuss the philosophical implications of this claim. (shrink)

This article examines the challenges and opportunities that arise with artificial intelligence (AI) and machine learning (ML) methods and tools when implemented within cultural heritage institutions (CHIs), focusing on three selected Swedish case studies. The article centres on the perspectives of the CHI professionals who deliver that implementation. Its purpose is to elucidate how CHI professionals respond to the opportunities and challenges AI/ML provides. The three Swedish CHIs discussed here represent different organizational frameworks and have different types of collections, while (...) sharing, to some extent, a similar position in terms of the use of AI/ML tools and methodologies. The overarching question of this article is what is the state of knowledge about AI/ML among Swedish CHI professionals, and what are the related issues? To answer this question, we draw on (1) semi-structured interviews with CHI professionals, (2) individual CHI website information, and (3) CHI-internal digitization protocols and digitalization strategies, to provide a nuanced analysis of both professional and organisational processes concerning the implementation of AI/ML methods and tools. Our study indicates that AI/ML implementation is in many ways at the very early stages of implementation in Swedish CHIs. The CHI professionals are affected in their AI/ML engagement by four key issues that emerged in the interviews: their institutional and professional knowledge regarding AI/ML; the specificities of their collections and associated digitization and digitalization issues; issues around personnel; and issues around AI/ML resources. The article suggests that a national CHI strategy for AI/ML might be helpful as would be knowledge-, expertise-, and potentially personnel- and resource-sharing to move beyond the constraints that the CHIs face in implementing AI/ML.

Here is a crucial question in the contemporary philosophy of perception: how can we be aware of action properties? According to the perceptual view, we consciously see them: they are present in our visual phenomenology. However, this view faces some problems. First, I review these problems. Then, I propose an alternative view, according to which we are aware of action properties because we imagine them through a special form of imagery, which I call visuomotor imagery. My account is to be (...) preferred as it offers an explanation of our awareness of action properties without generating all the problems that the perceptual view faces. (shrink)

Five hundred years after his death, Niccolò Machiavelli still draws an astonishing range of contradictory characterizations. Was he a friend of tyrants? An ardent republican loyal to Florence’s free institutions? The father of political realism? A revolutionary populist? A calculating rationalist? A Renaissance humanist? A prophet of Italian unification? A theorist of mixed government? A forerunner to authoritarianism? The master of the dark arts of intrigue? This book provides a vivid and engaging introduction to Machiavelli’s life and works that sheds (...) new light on his originality and relevance. Gabriele Pedullà—a leading Italian expert and acclaimed writer—offers fresh readings of the Florentine thinker’s most famous writings, The Prince and the Discourses on Livy, as well as lesser-known texts. A new and often surprising Machiavelli emerges: one closer to his time but also better suited to inform our own. Pedullà’s portrait of Machiavelli highlights his close attention to social and emotional bonds, staunch opposition to oligarchy, keen awareness of the economic side of power dynamics, and strong preference for history over philosophy as a guide for leaders. This book recovers the excitement Machiavelli roused in his first readers for a twenty-first-century audience, capturing his capacity to provoke, both then and now, with unconventional ideas and startling insights.

Does action play any crucial role in our perception of pictures? The standard literature on picture perception has never explicitly tackled this question. This is for a simple reason. After all, objects in a picture seem to be static objects of perception. Thus, it might sound extremely controversial to say that action is crucial in picture perception. Contrary to this general intuitive stance, this paper defends, for the first time, the apparently very controversial claim, never addressed in the literature, that (...) some of the specific and essential relations between vision and action make action (and its motoric basis) crucial in order for us to enter pictorial experience. I first discuss two ways in which vision and action are deeply linked, by describing the famous notions of Vision-for-Action and Sensorimotor Understanding. Then, I describe the special role they play in generating ordinary pictorial experience and suggest that, when we cannot rely on them while in front of a picture, we lose pictorial experience.

In two often neglected passages of the Critique of Pure Reason, Kant submits that the Critique is a 'treatise' or a 'doctrine of method'. These passages are puzzling because the Critique is only cursorily concerned with identifying adequate procedures of argument for philosophy. In this book, Gabriele Gava argues that these passages point out that the Critique is the doctrine of method of metaphysics. Doctrines of method have the task of showing that a given science is indeed a science (...) because it possesses 'architectonic unity' – which happens when it realizes the 'idea' of a science. According to Gava's novel approach, the Critique establishes that metaphysics is capable of this unity, and his reading of the Critique from this perspective not only illuminates the central role of the Transcendental Doctrine of Method within it, but also clarifies the relationship between the different parts of the work.

Kant’s account of practical justification for belief has attracted much attention in the literature, especially in recent years. In this context, scholars have generally emphasized the originality of Kant’s thought about belief (Glaube), and Kant indeed offers a definition of belief that is very different from views that were prevalent in eighteenth-century Germany. In this article, however, I argue that it is very likely that Christian August Crusius exerted influence on Kant’s definition of belief and his account of practical justification. (...) In turn, acknowledging this influence has relevant consequences for how we understand the phenomenology of Kantian belief. (shrink)

A complementary system for a given logic is a proof system whose theorems are exactly the formulas that are not valid according to the logic in question. This article is a contribution to the complementary proof theory of classical propositional logic. In particular, we present a complementary proof-net system, $$\textsf{CPN}$$ CPN, that is sound and complete with respect to the set of all classically invalid (one-side) sequents. We also show that cut elimination in $$\textsf{CPN}$$ CPN enjoys strong normalization along with (...) strong confluence (and, hence, uniqueness of normal forms). (shrink)

The last couple of decades have witnessed a renewed interest in the notion of inductive risk among philosophers of science. However, while it is possible to find a number of suggestions about the mitigation of inductive risk in the literature, so far these suggestions have been mostly relegated to vague marginal remarks. This paper aims to lay the groundwork for a more systematic discussion of the mitigation of inductive risk. In particular, I consider two approaches to the mitigation of inductive (...) risk—the individualistic approach, which maintains that individual scientists are primarily responsible for the mitigation of inductive risk, and the socialized approach, according to which the responsibility for the mitigation of inductive risk should be more broadly distributed across the scientific community or, even more broadly, across society. I review some of the argument for and against the two approaches and introduce two new problems for the individualistic approach, which I call the problem of precautionary cascades and the problem of exogenous inductive risk, and I argue that a socialized approach might alleviate each of these problems.

Molyneux’s question famously asks about whether a newly sighted subject might immediately recognize, by sight alone, shapes that were already familiar to her from a tactile point of view. This paper addresses three crucial points concerning this puzzle. First, the presence of two different questions: the classic one concerning visual recognition and another one concerning vision-for-action. Second, the explicit distinction, reported in the literature, between ocular and cortical blindness. Third, the importance of making reference to our best neuroscientific account on (...) vision, ‘the two visual systems model’, in order to better address Molyneux’s problem. Then, by offering a new, deeper analysis of the relation between, and, this paper suggests that the subjects of Molyneux’s two different questions show the same visual impairment as brain-damaged subjects with different lesions of the visual cortex. In particular, the subject of the first question shows the same impairment in visual recognition as a visual agnosic subject, while the subject of the second question shows the same visual impairment in visuomotor processing as an optic ataxic subject. These impairments still hold even if ocular processing is restored. Therefore, I suggest the following. For the first classic question, the required experimental setting cannot be properly reached. By contrast, concerning the second question, based on the interpretation we select, either the answer is negative, or, as with the first question, the experimental setting cannot be properly reached. This proposal constitutes, with the other approaches offered in the literature, a further attempt to tackle the enormous complexity of Molyneux’s puzzle. (shrink)

According to power theorists, properties are powers—i.e. they necessarily confer on their bearers certain dispositions. Although the power theory is increasingly gaining popularity, a vast majority of analytic metaphysicians still favors what I call ‘the nomic theory’—i.e. the view according to which what dispositions a property confers on its bearers is contingent on what the laws of nature happen to be. This paper argues that the nomic theory is inconsistent, for, if it were correct, then properties would not confer any (...) dispositions on their bearers—they would only appear to do so (just like how, in cases of mimicking, objects do not really have the relevant dispositions, they merely appear to have them). If my arguments are sound, then the nomic theory is incoherent and ultimately collapses into what I call ‘neo-occasionalism’ and powers turns out to be the only available option for those who believe that properties genuinely confer dispositions on their bearers.

In this paper, I distinguish scientific models in three kinds on the basis of their ontological status—material models, mathematical models and fictional models, and develop and defend an account of fictional models as fictional objects—i.e. abstract objects that stand for possible concrete objects.

I will be concerned with the following question: are there compelling arguments for postulating a distinction between the truth of a statement and the recognition of its truth, when truth is conceived along the lines of a suitable generalization of the intuitionistic idea that it should be characterized as the existence of a proof? I will argue that the distinction is not necessary within the conceptual framework of intuitionism by replying to two arguments to the contrary, one based on the (...) paradox of inference, the other on considerations concerning the content of a statement.

Public reason liberalism is defined by the idea that laws and policies should be justifiable to each person who is subject to them. But what does it mean for reasons to be public or, in other words, suitable for this process of justification? In response to this question, Kevin Vallier has recently developed the traditional distinction between consensus and convergence public reason into a classification distinguishing three main approaches: shareability, accessibility and intelligibility. The goal of this paper is to defend (...) the accessibility approach by demonstrating its ability to strike an appealing middle course in terms of inclusivity between shareability and intelligibility. We first argue against Vallier that accessibility can exclude religious reasons from public justification. Second, we use scientific reasons as a case study to show that accessibility excludes considerably fewer reasons than shareability. Throughout the paper, we connect our discussion of accessibility to John Rawls’s model of public reason, so as to give substance to the accessibility approach and to further our understanding of Rawls’s influential model.

Performance appraisals are widely used as an HR instrument. This study among 332 police officers examines the effects of performance appraisals from a behavioral ethics perspective. A mediation model relating justice perceptions of police officers’ last performance appraisal to their work affect, perceived supervisor and organizational support and, in turn, their ethical (pro-organizational proactive) and unethical (counterproductive) work behavior was tested empirically. The relationship between justice perceptions and both, ethical and unethical behavior was mediated by perceived support and work affect. (...) Hence, a singular yearly performance appraisal was linked to both ethical and unethical behaviors at work. The finding that ethical and unethical aspects of employee behavior share several of the same organizational antecedents, namely organizational justice perceptions, has strong practical implications which are discussed as well.

In this paper, I distinguish three general approaches to public trust in science, which I call the individual approach, the semi-social approach, and the social approach, and critically examine their proposed solutions to what I call the problem of harmful distrust. I argue that, despite their differences, the individual and the semi-social approaches see the solution to the problem of harmful distrust as consisting primarily in trying to persuade individual citizens to trust science and that both approaches face two general (...) problems, which I call the problem of overidealizing science and the problem of overburdening citizens. I then argue that in order to avoid these problems we need to embrace a (thoroughly) social approach to public trust in science, which emphasizes the social dimensions of the reception, transmission, and uptake of scientific knowledge in society and the ways in which social forces influence both positively and negatively the trustworthiness of science.

Recent evidence indicates that transcriptional bursts are intrinsically amplified by messenger RNA cytoplasmic processing to generate large stochastic fluctuations in protein levels. These fluctuations can be exploited by cells to enable probabilistic bet‐hedging decisions. But large fluctuations in gene expression can also destabilize cell‐fate commitment. Thus, it is unclear if cells temporally switch from high to low noise, and what mechanisms enable this switch. Here, the discovery of a post‐transcriptional mechanism that attenuates noise in HIV is reviewed. Early in its (...) life cycle, HIV amplifies transcriptional fluctuations to probabilistically select alternate fates, whereas at late times, HIV utilizes a post‐transcriptional feedback mechanism to commit to a specific fate. Reanalyzing various reported post‐transcriptional negative feedback architectures reveals that they attenuate noise more efficiently than classic transcriptional autorepression, leading to the derivation of an assay to detect post‐transcriptional motifs. It is hypothesized that coupling transcriptional and post‐transcriptional autoregulation enables efficient temporal noise control to benefit developmental bet‐hedging decisions. (shrink)
