The essay is dedicated to war considered through the reflections of Roger Caillois and in particular through certain motifs – feast, sacred, vertigo – that allow us to grasp its ‘metaphysical’ intention, i.e. capable of looking at war as the point of chiasmatic reversibility of life and death.

Parity games are combinatorial representations of closed Boolean μ-terms. By adding to them draw positions, they have been organized by Arnold and Santocanale [3] and [27] into a μ-calculus whose standard interpretation is over the class of all complete lattices. As done by Berwanger et al. [8] and [9] for the propositional modal μ-calculus, it is possible to classify parity games into levels of a hierarchy according to the number of fixed-point variables. We ask whether this hierarchy collapses w.r.t. the (...) standard interpretation. We answer this question negatively by providing, for each n≥1, a parity game Gn with these properties: it unravels to a μ-term built up with n fixed-point variables, it is not semantically equivalent to any game with strictly less than n−2 fixed-point variables.

Through a commentary of the letter sent by Husserl to the 8th International Congress of Philosophy in 1934, the essay intends to clarify the concept of “responsibility” as a “universal form” thanks to which the rational human being orients his acts according to a consciously ethical direction. By focusing on the dynamics that characterize the relationship between Logos and Ethos, is then pointed up Husserl’s aim to build a gnoseology that can’t be solved in an abstract intellectualism as it embodies (...) always a constructive criticism of the present and its aberrations. The appeal contained in the letter of 1934 for an epoché of every historical tradition becomes therefore the premise for an overcoming of past conceptual forms in order to reach the “implicit” concealed into every historical event and whose grasp and interpretation is possible only to the eidetic view of the phenomenologist.

Spatial memory relies on encoding, storing, and retrieval of knowledge about objects’ positions in their surrounding environment. Blind people have to rely on sensory modalities other than vision to memorize items that are spatially displaced, however, to date, very little is known about the influence of early visual deprivation on a person’s ability to remember and process sound locations. To fill this gap, we tested sighted and congenitally blind adults and adolescents in an audio-spatial memory task inspired by the classical (...) card game “Memory.” In this research, subjects had to find pairs among sounds displaced on an audio-tactile device composed of loudspeakers covered by tactile sensors. To accomplish this task, participants had to remember the spatialized sounds’ position and develop a proper mental spatial representation of their locations. The test was divided into two experimental conditions of increasing difficulty dependent on the number of sounds to be remembered. Results showed that sighted participants outperformed blind participants in both conditions. Findings were discussed considering the crucial role of visual experience in properly manipulating auditory spatial representations, particularly in relation to the ability to explore complex acoustic configurations.

Luigi Giussani, a high school religion teacher throughout the 1950s and 1960s, grounded his teachings in the vast body of experience to be found in Christianity's two-thousand-year history. He told his students, “I'm not here to make you adopt the ideas I will give you as your own, but to teach you a method for judging the things I will say.” Throughout his life, education was one of Giussani's primary intellectual interests. He believed that effective education required an adequate (...) background in the Christian tradition, presented within a lived experience that underscored the capacity of the faith to answer universal questions. What he proposed was a process that allowed one to sift through tradition, critically examining it and comparing it against the ultimate criteria for judgment: the desires of the heart. In Giussani's view, the primary concern was to “educate the human heart as God made it.” In The Risk of Education he states that fear leads students to associate this process of criticism with negativity or doubt. Yet, without an education in criticism, students cannot develop conviction. At a time when young people are abandoning the church and questioning the value of faith, Giussani's method of judging and verifying Christianity as an experience seems a necessary intervention. In The Risk of Education he argues that, ultimately, education and the Christian message reveal themselves through human freedom. (shrink)

Chapter 1 First Person Access to Mental States. Mind Science and Subjective Qualities -/- Abstract. The philosophy of mind as we know it today starts with Ryle. What defines and at the same time differentiates it from the previous tradition of study on mind is the persuasion that any rigorous approach to mental phenomena must conform to the criteria of scientificity applied by the natural sciences, i.e. its investigations and results must be intersubjectively and publicly controllable. In Ryle’s view, philosophy (...) of mind needs to adopt an antimentalist stance to achieve this aim. Antimentalism not only definitively rejects the idea that mind is a substance separated from the body, it also denies that mental phenomena radically differ from physical phenomena by virtue of several unique features. Most problematically, mental phenomena have a conscious character (mental states are related to specific qualitative feelings) and are accessible only to the first-person (only the subject knows directly what s/he is experiencing inside his/her mind). Ryle takes a strong stance on antimentalism going so far as to maintain that an approach to mind which aims to meet the criteria of scientificity set by the natural sciences must avoid any reference to internal, unobservable mental states. In his view (which is considered a specifically philosophical version of psychological behaviorism and also addresses questions put forward in psychological research), mental states can be redescribed in terms of behavioral dispositions. In this chapter, we address the historical roots of the antimentalist view and analyze its relation to the later tradition of research on mind. We show that, compared to the antimentalist stance, functionalism and cognitivism take a step back when they maintain that direct reference to mental states is necessary since mental states cause and therefore explain human behavior. This step backwards is often interpreted as a return to mentalism. However, this is only partially true. Indeed, we suggest that these later traditions retain one important element of Ryle’s antimentalism, i.e. the idea that mental states must be uniquely identified using external and publicly observable criteria, while excluding any reference to introspection and those qualitative dimensions of a mental state, which are accessible only to the first-person. According to the perspective we put forward, this epistemological stance has continued to influence contemporary research on mind and current philosophical and psychological theories which both tend to exclude the subjective qualities of human experience from their accounts of how the mind works. The issue we raise here is whether this is legitimate or whether subjective qualities do play a role with respect to the way our mind works. The conclusion of this chapter anticipates the argument the book makes in in favor of this latter position, starting from a particular angle, i.e. the problem of how we categorize concepts related to our internal states. -/- Chapter 2 The Misleading Aspects of the Mind/Computer Analogy. The Grounding Problem and the Thorny Issue of Propriosensitive Information -/- Abstract. After the crisis of behaviorism, cognitivism and functionalism became the predominant models in the field of psychology and of philosophy, respectively. Their success is mainly due to the new key they use for interpreting mental processes: the mind/computer analogy. On the basis of this analogy, mental operations are seen as cognitive processes based on computations, i.e. on manipulations of abstract symbols which are in turn understood as informational unities (representations). This chapter identifies two main problems with this model. The first is how these symbols can relate to and communicate with perception and thus allow us to identify and classify what we perceive through the senses. Here we limit ourselves to presenting this issue in relation to the classical symbol grounding problem originally put forward by Harnad on the basis of Searle’s Chinese room argument. An attempt to address the problem raised here will be made in chap. 3. The second point we discuss in relation to the mind/computer analogy concerns the idea of information it fosters. Indeed, following this analogy, information is something available in the external world which can be captured by the senses and transmitted to the central system without being influenced or modified by the procedures of transmission. This perspective does not take into account that – unlike computers – in living beings information is acquired by means of the body. As Ulric Neisser has already pointed out, the body is itself an informational source that provides us with additional sensory experience that influences (modifies or complements) the information extracted from the external world by the senses. To develop this line of analysis and to determine exactly what information is provided by the body and how this might influence cognition, we examine Sherrington’s and Gibson’s positions. Moving on from their views, we qualify bodily information in terms of ‘proprioception’. We use ‘proprioception’ in a broad sense to describe any kind of experience we have of our internal states (including postural information as well as sensations related to the general state of the body and its parts). Following Damasio’s and Craig’s studies, we further elaborate this position, arguing that living beings are equipped with an internal propriosensitive monitoring system which maps all the changes that constantly occur in our body and that give us perceptual (‘proprioceptive’ or propriosensitive) information about what happens inside us. Moreover, relying on Goldie’s and Ratcliffe’s view, we show that emotional information can also be considered as a form of ‘proprioception’ which contributes to determining everything we perceive. This analysis leads us to the second main thesis of this book: ‘proprioception’ is a form of internal perception and it is an essential component of the sensory information we can access and use for all cognitive purposes. -/- Chapter 3 Semantic Competence from the Inside: Conceptual Architecture and Composition -/- Abstract. Concepts are essential constituents of thought: they are the instruments we use to categorize our experience, i.e. to classify things and group them together in homogeneous sets. Here we define concepts as the internal mental information (representations) that allows us, among other things, to master words in natural language. By analyzing the way in which individuals master word meanings we explore a number of hypotheses regarding the nature of concepts. Following Diego Marconi’s research, we differentiate between two kind of abilities that underpin lexical competence – so-called ‘referential’ and ‘inferential competence’ – and we suggest that, in order to support these abilities, concepts must also include two corresponding kinds of information, i.e. inferential and referential information. We point out that the most widely used and acknowledged theories of concepts do not make this distinction, instead broadly characterizing the information used for categorization in terms of propositionally described feature lists. However, we show that while feature lists can explain inferential competence, they do not account for referential competence. To address the issue of referential competence we examine Ray Jackendoff’s hypothesis that to account for the possibility of linking perceptual and conceptual information we need to assume the existence of a (visual) representation that encodes the geometric and topological properties of objects and bridges the gap between the percept and the concept. Furthermore, we analyze the extension of this work by Jesse Prinz who introduced the notion of a proxytype, a perceptual representation of a class of objects that incorporates structural and parametric information related to their appearance. However, as we point out, proxytypes can only explain the relationship between perception and concepts with respect to instances that can be perceived through the senses and that belong to the same class by virtue of their physical similarity. We suggest that this notion be extended to include larger conceptual classes. To accomplish this, we further develop Mark Johnson, George Lakoff and Jean Mandler’s idea of a schematic image and argue that conceptual representations include a perceptual schema. Perceptual schemata are non-linguistic, structured experiential gestalts (patterns or maps) that make use of information taken from all sensory modalities, including body perception. They accomplish a quasi-conceptual function: they allow us to recognize and to classify different instances. In this work, we hypothesize that perceptual schemata are an essential component of concepts, but not identical to them. Instead, we suggest that concepts include both perceptual and propositional information with perceptual schemata providing the ‘perceptual core concept’ that grounds related propositional information. -/- Chapter 4 In the Beginning There Were Categories. The Bodily Origin of Prelinguistic Categorical Organization: The Example of Folkbiological Taxonomies -/- Abstract. Studies of categorization in psychology and the cognitive sciences have made use of the notions of ‘category’ and ‘concept’ without precisely defining what is meant by either; in fact, often these terms have been used as synonyms, making it difficult to address specific issues related to conceptual development. This chapter begins by discussing the definitions of, as well as the distinctions between, ‘categories’ and ‘concepts’ in the classical philosophical tradition (Aristotle, Kant and Husserl). We introduce our view of categories with reference to Husserl. Categorization is defined as the way in which our experience is originally (pre-linguistically) organized in a passive and fully unconscious manner on the basis of universal structuring principles. Conceptualization is explained as a later process in which the earlier categorical macro-classes are further subdivided into more specific and detailed sets; this later process also relies on linguistic learning and exposure to culture. On the basis of Ray Jackendoff, Jean Mandler, George Lakoff and Mark Johnson’s work, we hypothesize that categorization is a two-step process that begins with the formation of homogeneous sets of entities partitioned into regions that describe the ontological boundaries of the objects that humans perceive (categories) and continues at a later stage with the development of more specific classifications (concepts). In this chapter, we mainly address three related issues: Why should we assume that there is categorical organization which precedes the development of a conceptual system? How do categories and concepts relate to each other? Shall we hypothesize that categories are innate or that they are formed before concepts on the basis of information and organizational structure available at a very early developmental stage? We show that categorical partitions are necessary for categorization and, following Mandler, that the general categories we form at an early age do not match our adult superordinate concepts. As for the third issue, we argue that there might be no need to assume that categories are innately present in the human mind, since their formation can be explained – at least in certain cases – by basic mechanisms that work on body (propriosensitive) information. This hypothesis will not be discussed in general, but in relation to a particularly relevant example of categorical partition, i.e. the folk-biological dichotomy between ANIMATE/INANIMATE. This is compared with other dichotomies that derive from it, but are not directly categorical such as LIVING/NON-LIVING and BIOLOGICAL/NON-BIOLOGICAL. -/- Chapter 5 Internal States: From Headache to Anger. Conceptualization and Semantic Mastery -/- Abstract. Here we ask if we can also apply the distinction between referential and inferential competence we introduced in Chapter 3 to words that do not refer to things that are perceived using the external senses, especially to words/concepts that denote bodily experiences (such as pain, thirst, hunger, etc.) or emotions. We introduce and discuss the hypothesis that – even though such words/concepts do not refer to intersubjectively identifiable entities in the external world – they do have a kind of referent that can be accessed via direct perception, more specifically ‘proprioception’, as we have defined it in terms of all propriosensitive information we can consciously access. In the first part of the chapter, we specifically consider terms denoting bodily experiences such as ‘pain’ or ‘hunger’ and argue that their referents are identified and classified from a first-personal point of view on the basis of four main characteristics: their specific intensity, their localization in the body, their co-occurrence with other signals and above all their specific qualitative sensations. Emotions are addressed in the second part of the chapter. We suggest that there is a continuity between bodily experiences and emotions. In particular, we argue for a perceptual theory of emotions in line with that proposed by James and Lange at the end of the 19th century and developed more recently by authors such as Damasio (see also chap. 2§5, §6). The hypothesis we put forward is that the referential information that supports the categorization of emotions and therefore also our mastery of terms referring to emotions consists in the perception (i.e. the ‘proprioception’) of those bodily states and changes in bodily states which constitute our emotional experience. In the context of this discussion we examine some objections to this line of reasoning that arise from a cognitivist perspective and following authors such as Oatley, Johnson-Laird and Frijda, we distinguish between basic emotions that can be identified and classified solely on the basis on how they feel and complex emotions whose identification and classification additionally depends on cognitive factors. To describe how emotions are identified and classified on the basis of how they feel, we rely on Marcel and Lambie’s distinction between an ‘emotion state’ and an ‘emotion experience’. Both notions indicate kinds of feelings that we consciously experience. However, they describe first-order and second order emotion awareness respectively. The emotion state is the feeling we have of the bodily states and changes that occur when we are experiencing an emotion, while the emotion experience is the fully developed and integrated emotion we both experience and are, with reflection, aware of experiencing. On the basis of this differentiation, we also show that the same characteristics that aid in the identification and classification of bodily experiences (specific qualitative sensations; somatic localization; specific intensity; presence/absence of specific concomitant sensations) can also be used for the identification and classification of emotions – at least basic emotions. In the last two sections of the chapter we present some clinical evidence on the semantic competence of people who suffer from Alexithymia and Autism Spectrum Disorder which supports the conclusions of our preceding analyses. -/- Chapter 6 The ‘Proprioceptive’ Component of Abstract Concepts -/- Abstract. In this chapter, we address the issue of whether the mastery of abstract words requires only inferential knowledge and thus, if the concepts that support the mastery of abstract words include only linguistic information. We start by differentiating the notions of ‘abstract’ and ‘general’ which are often erroneously confused. We then identify a strict definition of abstract, as contrasted with ‘concrete’, that applies to words or concepts whose referent cannot be experienced by the senses. We argue that abstract words/concepts would be better described as theoretical, because they are usually conceived as structured sets of inferential knowledge expressed linguistically; that is, as small theories. Pointing out parallels with Carnap’s analysis of this issue in philosophy of science, we hypothesize that words/concepts denoting non-observable entities are not all ‘equally theoretical’, because their link to sensory experience can be stronger or weaker. We revive the distinction, inspired by Quine, between theoretical and intertheoretical concepts/words. This distinction relies on the fact that the former – unlike the latter – retains a strong, although indirect, connection with perception. In Quine’s discussion, perception is understood uniquely in terms of observability, i.e. of external sensory experience. Here we argue, however, that bodily, ‘proprioceptive’ (i.e. propriosensitive) experience can also serve to referentially ground theoretical (i.e. abstract) concepts/words. We frame this issue using the example of the theoretical concept ‘freedom’ and Lakoff’s hypothesis that this concept is developed on the basis of bodily information. We contrast this with the example of ‘democracy’ which more closely resembles an intertheoretical concept/word. Furthermore, we show that one of the classical views put forward in psycholinguistic research to explain how abstract concepts are mentally represented – i.e. Paivio’s Dual Coding Theory – points in the same direction as our analysis. The same is true of Barsalou’s work suggesting that we use internal information to understand at least some abstract words. To sustain this position, we put forward two lines of evidence: the first comes from psycholinguistic studies while the second examines deficits of semantic competence exhibited by people with Autism Spectrum Disorder. On the basis of our analysis, we put forward a classification that distinguishes between different kinds of concreteness and different degrees of abstraction: concepts/words referring to body experiences and basic emotions are described as analogous to concrete concepts/words because they are grounded in perceptual (i.e. propriosensitive) experience, while abstract concepts/words are considered more or less abstract depending on whether they are intratheoretical (and rely entirely on inferential information) or theoretical (and are partially grounded in perceptual – or more often in propriosensitive perceptual – information). In the last section of the chapter we consider two scales that have been used in psycholinguistic research to measure the degree of concreteness vs. abstractness of words and we show that – used conjointly – they can provide a measure of the internal vs. external grounding of specific words.

Nel mio articolo propongo una lettura dei §§ 79-84 della Critica del Giudizio, parte della sezione Metodologia del Giudizio teleologico. Dapprima mi interrogo sul significato di una Methodenlehre del Giudizio teleologico, che rintraccio in un’attività metariflessiva del Giudizio; procedo poi ad una lettura analitica del testo nelle sue varie articolazioni, nella quale passo in rassegna le questioni attinenti alla specificità dello statuto epistemologico della teleologia, alla possibile convivenza tra finalismo e meccanicismo nella scienza della natura, all’origine della vita, allo scopo (...) ultimo della natura e allo scopo finale della creazione; approdo, infine, ad un’interpretazione per cui l’intera teleologia rationis humanae, che si estende dalla teleologia naturale alla teleologia morale passando per l’antropologia e per la filosofia della storia, viene in questa sezione riarticolata intorno ad un nuovo fulcro concettuale di livello trascendentale, che può garantire l’effettivo collegamento tra queste diverse parti della filosofia proprio perché esso non si esercita in forma di dominio legislativo, ma in forma di riflessione sul molteplice empirico e sulla causalità teleologica propria dell’uomo.

A fronte di rapide trasformazioni geo-politiche globali, il tema dei diritti fondamentali - quale sia la loro struttura, quali debbano considerarsi tali, in qual modo li si possa garantire, quale il rapporto con la cittadinanza e la democrazia - acquista sempre maggiore rilevanza nella discussione pubblica. Luigi Ferraioli propone su questi problemi un'originale e innovativa riflessione, suscitando un dibattito in cui si coniugano rigore scientifico e passione civile.

The first part of this paper aims to highlight the analogies between Schutz’s vision of the natural attitude and Wittgenstein’s vision of a phenomenon that concerns the same problematic field, i.e. certainty, the belief of common sense that is free of all doubt, that the world “out there” is as it appears, absolutely real. These certainties form the basis, the foundation of language games and therefore of knowledge in general and in its entirety. This foundation is unfounded and yet indispensable. (...) The second part of the paper examines an important topic analysed by Wittgenstein, related to the aforementioned problem: the language transposition of pre-predicative, pre-reflective and non-propositional certainties, the cornerstones of which are “hinge propositions”, whose hybrid nature can be identified in the shift from empirical propositions to grammatical rules.

In the course of 1901, V. Crémieu published the results of some experiments carried out to test the magnetic effects of electric convection currents. According to Crémieu, his experiments had proved that convection currents had no magnetic effects and consequently they were not equivalent to conduction currents, that is they were not ‘real’ electric currents. These negative results conflicted with those of well-known experiments carried out by other researchers, in particular with Rowland's experiments, and with Maxwell's, Hertz's and Lorentz's theories, (...) which was more shocking. The publication of Crémieu's experiments raised a controversy which involved directly or indirectly some leading French and British physicists, and led Rowland together with his student Pender to re-perform his experiments. Pender's results confirmed those preiously obtained by Rowland, in striking conflict with those of Crémieu. The importance of Crémieu's experiments was stressed by Poincaré in some of his publications, where he analysed and criticized various aspects of the question. However, he was involved more deeply: his correspondence with Crémieu shows that many of the experiments performed by Crémieu were conceived by Poincaré and carried out with his guidance. To put an end to the controversy, Poincaré obtained Kelvin's support to organize Crémieu's and Pender's joint experiments. The results of these experiments showed that the conflicting results obtained previously were due to an ‘anomalous’ behaviour of the dielectrics used by Crémieu in his apparatus. (shrink)

Simple assumptions represent a decisive reason to prefer one theory to another in everyday scientific praxis. But this praxis has little philosophical justification, since there exist many notions of simplicity, and those that can be defined precisely strongly depend on the language in which the theory is formulated. The language dependence is a natural feature—to some extent—but it is also believed to be a fatal problem, because, according to a common general argument, the simplicity of a theory is always trivial (...) in a suitably chosen language. But, this trivialization argument is typically either applied to toy-models of scientific theories or applied with little regard for the empirical content of the theory. This paper shows that the trivialization argument fails, when one considers realistic theories and requires their empirical content to be preserved . In fact, the concepts that enable a very simple formulation, are not necessarily measurable, in general. Moreover, the inspection of a theory describing a chaotic billiard shows that precisely those concepts that naturally make the theory extremely simple are provably not measurable. This suggests that—whenever a theory possesses sufficiently complex consequences—the constraint of measurability prevents too simple formulations in any language. This explains why the scientists often regard their assessments of simplicity as largely unambiguous. In order to reveal a cultural bias in the scientists’ assessment, one should explicitly identify different characterizations of simplicity of the assumptions that lead to different theory selections. General arguments are not sufficient. (shrink)

_Abstract_: In this paper, I will examine the Goldstein-Cassirer approach to neuropathology to determine its current potential for yielding valuable insights. To this end, I will reconstruct the philosophical and theoretical underpinnings of such a standpoint in the first four sections. What will emerge is that it entails a definition of pathology as the loss of balance in the adaption of human beings to the environment, leading to a lack of proclivity to categorical behaviour and symbolic performances. Furthermore, we will (...) see that there are behavioural alterations which are not related to the locus of lesions. In the fifth section, I will compare and contrast the holistic stances with current research in neuropsychology. The sixth section is dedicated to conclusive remarks. _Keywords_: Psychopathology; Neuropathology; Ernst Cassirer; Kurt Goldstein; Holism _ La mente ordinatrice. La concezione di Goldstein e Cassirer della neuropatologia e la sua rilevanza oggi _ _Riassunto_: In questo articolo intendo analizzare l’approccio Goldstein-Cassirer alla neuropatologia per comprendere se esso può rivelarsi ancora utile alla luce delle ricerche attuali. A tal fine, ne ricostruirò le basi filosofiche e teoriche nei primi tre paragrafi. Scopriremo che esso implica una definizione di patologia come perdita di equilibrio nell’adattamento degli esseri umani all’ambiente, a seguito della quale viene a mancare la naturale tendenza verso il “comportamento categoriale” e le prestazioni simboliche. Vedremo, inoltre, che vi sono alterazioni del comportamento non collegabili al sito delle lesioni. Nel quinto paragrafo, metterò a confronto le istanze olistiche con le ricerche contemporanee nel campo della neuropsicologia. Il sesto paragrafo contiene le considerazioni conclusive. _Parole chiave_: Psicopatologia; Neuropatologia; Ernst Cassirer; Kurt Goldstein; Olismo. (shrink)

In this paper, I will deal with the analogy between Cassirer’s interpretation of relativity and his philosophy of culture. As to the structure of the paper, it will be divided into six parts. I will start with a brief introduction, after which I will succinctly outline Cassirer’s reading of Einstein’s theory, and in particular of general covariance. I will then focus on the presentation of his project for a “systematic philosophy” in the last chapter of Einstein’s Theory of Relativity and (...) subsequently delve into the lexical references to relativity made in Philosophy of Symbolic Forms. After this, I will tackle Cassirer’s rectorship speech, where relativity and the philosophy of culture are explicitly interwoven, but with the important clarification (already provided in Einstein’s Theory of Relativity and Philosophy of Symbolic Forms) that not all kinds of knowledge align with de-anthropomorphized objectivity. The final section contains the concluding remarks. (shrink)
