The concept of agency is of crucial importance in cognitive science and artificial intelligence, and it is often used as an intuitive and rather uncontroversial term, in contrast to more abstract and theoretically heavy-weighted terms like “intentionality”, “rationality” or “mind”. However, most of the available definitions of agency are either too loose or unspecific to allow for a progressive scientific program. They implicitly and unproblematically assume the features that characterize agents, thus obscuring the full potential and challenge of modeling agency. (...) We identify three conditions that a system must meet in order to be considered as a genuine agent: a) a system must define its own individuality, b) it must be the active source of activity in its environment (interactionalasymmetry) and c) it must regulate this activity in relation to certain norms (normativity). We find that even minimal forms of proto-celular systems can already provide a paradigmatic example of genuine agency. By abstracting away some specific details of minimal models of living agency we define the kind of organization that is capable to meet the required conditions for agency (which is not restricted to living organisms). On this basis, we define agency as an autonomous organization that adaptively regulates its coupling with its environment and contributes to sustaining itself as a consequence. We find that spatiality and temporality are the two fundamental domains in which agency spans at different scales. We conclude by giving an outlook to the road that lies ahead in the pursuit to understand, model and synthesis agents. (shrink)

The notion of information processing has dominated the study of the mind for over six decades. However, before the advent of cognitivism, one of the most prominent theoretical ideas was that of Habit. This is a concept with a rich and complex history, which is again starting to awaken interest, following recent embodied, enactive critiques of computationalist frameworks. We offer here a very brief history of the concept of habit in the form of a genealogical network-map. This serves to provide (...) an overview of the richness of this notion and as a guide for further re-appraisal. We identify 77 thinkers and their influences, and group them into seven schools of thought. Two major trends can be distinguished. One is the associationist trend, starting with the work of Locke and Hume, developed by Hartley, Bain, and Mill to be later absorbed into behaviorism through pioneering animal psychologists (Morgan and Thorndike). This tradition conceived of habits atomistically and as automatisms (a conception later debunked by cognitivism). Another historical trend we have called organicism inherits the legacy of Aristotle and develops along German idealism, French spiritualism, pragmatism, and phenomenology. It feeds into the work of continental psychologists in the early 20th century, influencing important figures such as Merleau-Ponty, Piaget, and Gibson. But it has not yet been taken up by mainstream cognitive neuroscience and psychology. Habits, in this tradition, are seen as ecological, self-organizing structures that relate to a web of predispositions and plastic dependencies both in the agent and in the environment. In addition, they are not conceptualized in opposition to rational, volitional processes, but as transversing a continuum from reflective to embodied intentionality. These are properties that make habit a particularly attractive idea for embodied, enactive perspectives, which can now re-evaluate it in light of dynamical systems theory and complexity research.

The enactive approach to cognition distinctively emphasizes autonomy, adaptivity, agency, meaning, experience, and interaction. Taken together, these principles can provide the new sciences of language with a comprehensive philosophical framework: languaging as adaptive social sense-making. This is a refinement and advancement on Maturana’s idea of languaging as a manner of living. Overcoming limitations in Maturana’s initial formulation of languaging is one of three motivations for this paper. Another is to give a response to skeptics who challenge enactivism to connect “lower-level” (...) sense-making with “higher-order” sophisticated moves like those commonly ascribed to language. Our primary goal is to contribute a positive story developed from the enactive account of social cognition, participatory sense-making. This concept is put into play in two different philosophical models, which respectively chronicle the logical and ontogenetic development of languaging as a particular form of social agency. Languaging emerges from the interplay of coordination and exploration inherent in the primordial tensions of participatory sense-making between individual and interactive norms; it is a practice that transcends the self-other boundary and enables agents to regulate self and other as well as interaction couplings. Linguistic sense-makers are those who negotiate interactive and internalized ways of meta-regulating the moment-to-moment activities of living and cognizing. Sense-makers in enlanguaged environments incorporate sensitivities, roles, and powers into their unique yet intelligible linguistic bodies. We dissolve the problematic dichotomies of high/low, online/offline, and linguistic/nonlinguistic cognition, and we provide new boundary criteria for specifying languaging as a prevalent kind of human social sense-making.

In this chapter we use methods of corpus linguistics to investigate the ways in which mathematicians describe their work as explanatory in their research papers. We analyse use of the words explain/explanation (and various related words and expressions) in a large corpus of texts containing research papers in mathematics and in physical sciences, comparing this with their use in corpora of general, day-to-day English. We find that although mathematicians do use this family of words, such use is considerably less prevalent (...) in mathematics papers than in physics papers or in general English. Furthermore, we find that the proportion with which mathematicians use expressions related to ‘explaining why’ and ‘explaining how’ is significantly different to the equivalent proportion in physics and in general English. We discuss possible accounts for these differences. (shrink)

[Does the gymnosophist’s reply to Alexander’s question on the origin of time indeed reflect an Indian doctrine?] The episode of Alexander’s interview with the gymnosophists has come down to us in several versions, among which the one in Plutarch’s Vita Alexandri is the most renowned. In this connection, the question arises whether the solutions given by the naked philosophers to the puzzles propounded by Alexander can be shown to reflect genuine Indian doctrines. Challenging Dumézil’s reply in the affirmative, the author (...) contends that they cannot. While most questions and answers are scarcely relevant to the investigation, as being of little (if any) philosophical import, the analysis concentrates on the more significant ones, and especially on the solution offered to the question as to which of the two — day or night — came first. According to Dumézil, the gymnosophist’s answer reported by Plutarch, i. e. that the day came first, by one day, reflects the vedic doctrine of the primeval cosmogonic role of Dawn and Light. Against this may be argued in the first place that such doctrine does not enjoy any prominent status in the Vedas themselves — quite to the contrary, it stands up disadvantegeously to many all-important texts, such as the Nāsadīyasūkta, which assign the primeval status to Darkness — and cannot therefore be regarded as being specifically Indian any more than its opposite. Secondly, it is shown that the Greek tradition is at great variance on this very point, to the extent that all logically conceivable solutions (i. e., precedence of day by one day / day by one night / night by one day / night by one night) are represented in some version or other. This inconsistency appears to stem from the fact that no particular doctrine (Indian or whatever) was envisaged; according to the present author, we have reason to believe that the gymnosophist’s reply was rather meant to set off by means of a paradox the sheer impossibility of a solution (all four alternatives being equivalent to that effect). This interpretation is reinforced by the gymnosophist’s own remark confessing the aporetical nature of his reply, and finally by a further recourse to paradox — this time a variant of the well-known “paradox of the liar” — which the author lays bare in the otherwise inexplicable dénouement of the anecdote.

Recreational Drugs European Network (ReDNet) project aims to use the Psychonaut Web Mapping Project database (Psychonaut Web Mapping Group, 2009) containing novel psychoactive compounds usually not mentioned in the scientific literature and thus unknown to clinicians as a unique source of information. The database will be used to develop an integrated ICT prevention approach targeted at vulnerable individuals and focused on novel synthetic and herbal compounds and combinations. Particular care will be taken in keeping the health professionals working directly with (...) young people showing problematic behaviors regularly updated in terms of novel compounds and combinations as well. A user-friendly project website will be developed aimed primarily at delivering the information/prevention approaches, but will also be a way of communicating with project partners and relevant stakeholders (e.g. thematic forum facilities, instant messages, blogs, video chat, wikiblog, newsletters distributed via mailing list). The website will support various ICT prevention tools, including an SMS alert service. Different areas and sections will be aimed specifically at the different target groups. -/- . (shrink)

ITA: Quello del “buon europeo” è in Nietzsche un tema significativo, che si presenta originariamente connesso alle riflessioni di Nietzsche sulla cultura europea, arricchendosi col tempo di una portata filosofica che si lega agli obiettivi del suo pensiero maturo. Scopo del presente articolo è di mostrare la genesi e l’evoluzione di tale concetto, a partire dalle sue prime occorrenze in Umano, troppo umano I fino al suo compiuto sviluppo negli scritti del 1885-87. Tale studio permetterà di evidenziare il particolare valore (...) che Nietzsche attribuisce ai “buoni europei”, in quanto promotori dello sviluppo spirituale conseguente alla compiuta liberazione della morale cristiana.

In the final section we (...) sum up the overall meaning of the «Wirkungsgeschichte» of Jonas’ philosophy in Italy and highlight possible lines of research still to be accomplished. (shrink)

Il lavoro consiste in un'analisi del concetto di essere in Aristotele considerandolo dal punto di vista dell'espressione "to ti en einai". L'essere in quanto tale non è tematizzato in quanto tale, ma visto come sinonimo di ente, e questo nel suo significato principale di "ousia".

Nel contributo, partendo da una prospettiva teoretica, ci si prefigge di analizzare i rapporti fra la filosofia indiana di Śaṃkara (il massimo filosofo del Vedānta, vissuto nell’VIII sec. d. C.) e il pensiero di Bergson. Da un simile punto di vista diviene infatti possibile una riflessione critica e interpretativa sui testi dei due autori, utile a chiarire alcuni problemi ermeneutici del pensiero śaṃkariano. Reciprocamente, la conoscenza del pensiero di Śaṃkara permette di illuminare e chiarire aspetti problematici della filosofia bergsoniana, in (...) particolare il rapporto fra materia e memoria e l’autentico significato di élan vital. Il saggio utilizza il concetto di advaita (non-dualità) - uno degli elementi chiave della filosofia vedantica – verso un superamento del dualismo materia/spirito, così come è stato affrontato anche dal filosofo francese nel xx secolo. Per svolgere questa interpretazione si approfondiscono poi i concetti di coscienza nei due filosofi, e la nozione di brahman-ātman intesa come trascendentale “non kantiano”, nella logica di smarcamento dalla prospettiva kantiana che era l’obiettivo dichiarato fin dai primi sviluppi della filosofia bergsoniana, contenuti nell’opera del 1889, Saggio sui dati immediati della coscienza.

Il breve saggio si propone di esaminare la centralità della figura materna nell’opera di un ingegnoso costruttore di storie della letteratura italiana del Novecento: Alberto Moravia. La scelta dell’Autore nasce dalla rilevanza della tematica nella sua opera, in cui peraltro è quasi sempre assente il punto di vista femminile delle “voci” delle donne. Ciò sembra paradossale e questa circostanza è di grande interesse critico. In particolare, a dispetto delle interpretazioni più canoniche, secondo cui Moravia – negli scritti realizzati tra il (...) 1929 e il 1964 – ha inteso compiere una “distruzione” dell’immagine materna nel quadro di una visione pessimista della famiglia borghese, dovremo considerare un più complesso e articolato universo materno nello scrittore romano, in cui è possibile ricostruire cinque modelli – la “madre autoritaria”, la “madre-non madre”, la “madre padrona”, la “madre-angelo custode” e la “madre-seduttrice” –, ben esemplificati nei principali romanzi ma che si ritrovano nei racconti che Moravia scrive ininterrottamente dagli anni Trenta agli anni Sessanta, la cui mole ha determinato, ancor oggi, una mancanza di studi sistematici. In secondo luogo, la tematica della madre sarà esaminata nelle trasposizioni cinematografiche italiane delle opere letterarie di Moravia. Va ricordato che il rapporto dello scrittore con il cinema fu particolarmente intenso. Per un verso, la “settima arte” rivestì un ruolo non secondario nella formazione ed esperienza estetica dell’Autore romano, che al cinema si interessò anche professionalmente nelle vesti di critico cinematografico, a partire dal primo dopoguerra, dapprima, per La nuova Europa e Libera stampa, poi, per L’Europeo e L’Espresso, a cui dobbiamo aggiungere l’attività di saggista per numerose riviste specializzate. Per altro verso, il cinema italiano non solo ha attinto a “mani basse” dall’opera di Moravia per sceneggiature di pellicole, che furono pietre miliari della sua storia. L’elenco dei romanzi e racconti adattati al grande schermo rende conto della grande influenza nella cultura italiana degli anni Cinquanta e Sessanta: La provinciale (1953) di Mario Soldati, La romana (1954) di Luigi Zampa, Peccato che sia una canaglia (1954) di Alessandro Blasetti, Racconti romani (1955) di Gianni Franciolini, La ciociara (1960) di Vittorio de Sica, La giornata balorda (1960) di Mauro Bolognini, Risate di gioia (1960) di Mario Monicelli, Agostino (o la perdita dell’innocenza) (1962) di Mauro Bolognini, La noia (1963) di Damiano Damiani, Gli indifferenti (1964) di Francesco Maselli, Le ore nude (1964) di Marco Vicario, La donna invisibile (1969) di Paolo Spinola, Una ragazza piuttosto complicata (1969) di Damiano Damiani, L’amore coniugale (1970) di Dacia Maraini, Il conformista (1970) di Bernardo Bertolucci, e molti altri ancora. Come avremo modo soltanto di accennare, il successo della letteratura moraviana nel mondo del cinema italiano si deve a molteplici fattori, tra cui la raffigurazione dei personaggi e degli ambienti, la focalizzazione su certe tematiche e, non da ultimo, lo stile narrativo, particolarmente adatto alle trasposizioni cinematografiche. Come caso di studio, ci soffermeremo, infine, sulla figura materna della versione filmica de La noia di Damiani, con l’obiettivo di verificare se nel passaggio dal libro alla pellicola, quella particolare connotazione della madre autoritaria abbia subito delle alterazioni. L’ipotesi che muove l’analisi è che la stesura delle sceneggiature, la raffigurazione dei personaggi e la messa in scena delle sequenze filmiche facciano emergere un riadattamento adeguato al largo pubblico, con il sovvertimento dell’andamento cronologico, alcune “lacune” di ordine psicologico nella raffigurazione dei protagonisti e un certo cedimento moralistico alla cultura ancora dominante negli anni ’50 e ’60, in cui la figura materna, sia quando è incattivita dalla povertà che quando è inaridita dalla ricchezza, anela comunque agli affetti familiari, trovando in essi una qualche forma di redenzione.

È una credenza diffusa che i marchi di origine (DOCG, DOC, DOP, IGT, IGP e PAT, rispettivamente: di origine controllata e garantita; di origine controllata; di origine protetta; indicazione geografica tipica; indicazione geografica protetta; prodotti agroalimentari tradizionali) siano di grande utilità sia per i consumatori che per i produttori: certificando l’origine e il metodo di produzione di un prodotto, essi ne garantiscono una certa qualità di fronte al consumatore. Ma è proprio così? Che cosa giustifica l’introduzione di un marchio di (...) origine? Quanto sostengo qui di seguito è che, sebbene non credo si possa negare che i marchi di origine segnalino anche una certa qualità di un prodotto, forse non sono il modo migliore per farlo. Di fatto, per il consumatore, i marchi non garantiscono niente che vada oltre alla qualità richiesta affinché la certificazione venga rilasciata; ma, al contempo, in quanto forme di protezionismo, favoriscono certi produttori, prevenendo l’utilizzo della denominazione a chi offre un prodotto di qualità analoga o superiore, ma provienente da una zona priva di tradizioni. In altre parole: se vi sono prodotti equiparabili per qualità e gusto ad un dato prodotto di origine, e possibilmente più economicamente vantaggiosi, il consumatore non avrà modo di accorgersene dalla sola nomenclatura. Quindi: i marchi di origine sono (talvolta) un ostacolo all’acquisto e al godimento dei prodotti migliori al miglior prezzo. Talvolta: questo deve essere ben sottolineato, poiché in certi casi (per esempio quello dei PAT) il prodotto certificato dal marchio ha un mercato talmente di nicchia da costituire un tuttuno tra qualità e origine. (Si potrebbe aggiungere che le certificazioni dei marchi non sono sempre ottenute attraverso procedure affidabili.

The present essay provides an overview of the images of seventeenth-century philosophy in the Rivista di storia della filosofia (then retitled Rivista critica di storia della filosofia) in the years 1946–1983. Founded in 1946 by Mario Dal Pra, the journal promoted a new anti-idealistic approach to the history of philosophy. Based on philological accuracy, this approach enhanced the complexity of history and the interdependence of different fields of knowledge. In particular, the unprecedented emphasis on the connections between science and philosophy (...) entailed a preeminent place for empiricism in the Rivista. This explains why this essay focuses on empiricist currents in seventeenth-century philosophy and especially on three of their representatives, namely Galileo Galilei, Thomas Hobbes and Francis Bacon.

“Dalla filosofia dell’azione alla filosofia della mente” è stato il percorso di alcuni filosofi di nazionalità varia degli anni 1980 – come Paul Churchland negli Stati Uniti o Ansgar Beckermann in Germania – che prima si sono interessati agli aspetti più teorici nella filosofia dell’azione, come il modo di funzionamento delle azioni e la loro spiegazione scientifica, e che poi, con l’arrivo e la diffusione dei personal computers e delle scienze cognitive, hanno ampliato e approfondito questo interesse di ricerca e (...) si sono dedicati alla filosofia della mente più in generale e in particolare alla spiegazione scientifica e filosofica del mentale. Sandro Nannini faceva parte di questo movimento ed è stato uno tra gli inizialmente pochi filosofi italiani che si sono occupati di questi argomenti; successivamente ne è diventato uno dei maggiori specialisti in Italia, proponendo una sua particolare versione di naturalizzazione del mentale. Subordinata agli interessi teorici è stata la sua iniziativa accademica di fondare e promuovere il primo dottorato italiano di ricerca in Scienze Cognitive. Il presente volume tratta dell’opera di Sandro Nannini in contributi che sono riflessioni più o meno specifiche sulle differenti tappe del suo percorso, affrontando temi come l’analisi dell'azione, il libero arbitrio, la discussione di Nannini di vari classici della filosofia, la tendenza del naturalismo a dissolvere la filosofia in un enciclopedismo empirico e la sfida dei qualia e della fenomenologia all’approccio naturalistico alla mente. Il volume contiene inoltre un saggio dello stesso Sandro Nannini, nel quale espone l’ultimo sviluppo della sua filosofia della mente nonché le risposte agli interventi degli altri autori: Mario De Caro, Sara Dellantonio, Rosaria Egidi, Roberta Lanfredini, Christoph Lumer, Paolo Parrini, Pietro Perconti, Claudio Pizzi, Emanuela Scribano e Giuseppe Varnier.

The study of active matter systems demonstrates how interactions might co-constitute agential dynamics. Active matter systems are comprised of self-propelled independent entities which, en masse, take part in complex and interesting collective group behaviors at a far-from-equilibrium state (Menon, 2010 ; Takatori & Brady, 2015 ). These systems are modelled using very simple rules (Vicsek at al. 1995), which reveal the interactive nature of the collective behaviors seen from humble to highly complex entities. Here I show how the study of (...) active matter systems supports two related proposals regarding interaction and agency. First, I argue that the study of interactive dynamics in these systems evidences the utility of treating interaction as an ontological category (Longino, 2021 ) and challenges methodological individualism as the received explanatory primitive in the study of agency. Second, the methods used to research active matter systems demonstrate how a minimal approach to agency can scale up in studying interactive agential dynamics in more complex systems. The examples of coordination dynamics (Kelso, 2001 ) and participatory sense-making (De Jaegher & Di Paolo, 2007 ) are provided to show how understanding agency requires us to look beyond the individuals to the interactive agential dynamics that can guide, scaffold, or constrain their activity.

In this essay I seek to critically evaluate some forms of holism and organicism in biological thought, as a more deflationary echo to Gilbert and Sarkar's reflection on the need for an 'umbrella' concept to convey the new vitality of holistic concepts in biology (Gilbert and Sarkar 2000). Given that some recent discussions in theoretical biology call for an organism concept (from Moreno and Mossio’s work on organization to Kirschner et al.’s research paper in Cell, 2000, building on chemistry to (...) articulate what they called “molecular vitalism,” studying the “vitalistic” properties of molecular, cellular, and organismal function, and Pepper and Herron’s suggestion in their 2008 paper that organisms define a category that evolutionary biology cannot do without), the question, what concept of organicism are they calling for? To what extent are such claims philosophically committed to a non-naturalistic concept of organism as organizing centre, as a foundational rather than heuristic concept – or possibly a “biochauvinism,” to use Di Paolo’s term (Di Paolo 2009)? My aim in this paper is to conceptually clarify the forms of holism and organicism that are involved in these cases (and I acknowledge that the study of early 20th-century holisms [Peterson 2010] indicates that not all of them were in fact ‘organicist’ or ‘biologistic’). I suggest that contemporary holists are still potentially beholden to a certain kind of vitalism or “biochauvinism”; but that when they reduce their claims to mere heuristics, conversely, they risk losing sight of a certain kind of organizational “thickness”, a “vital materiality” (Wheeler 2010) which is characteristic of biological systems (Bechtel 2007). And I ask if it is possible to articulate a concept of biological holism or organicism which is neither an empirical ‘biochauvinism’ nor a metaphysical ‘vitalism’? (shrink)

Whether collective agency is a coherent concept depends on the theory of agency that we choose to adopt. We argue that the enactive theory of agency developed by Barandiaran, Di Paolo and Rohde (2009) provides a principled way of grounding agency in biological organisms. However the importance of biological embodiment for the enactive approach might lead one to be skeptical as to whether artificial systems or collectives of individuals could instantiate genuine agency. To explore this issue we contrast the (...) concept of collective agency with multi-agent systems and multi-system agents, and argue that genuinely collective agents instantiate agency at both the collective level and at the level of the component parts. Developing the enactive model, we propose understanding agency – both at the level of the individual and of the collective – as spectra that are constituted by dimensions that vary across time. Finally, we consider whether collectives that are not merely metaphorically ‘agents’ but rather are genuinely agentive also instantiate subjectivity at the collective level. We propose that investigations using the perceptual crossing paradigm suggest that a shared lived perspective can indeed emerge but this should not be conflated with a collective first-person perspective, for which material integration in a living body may be required.

Early modern automata, understood as efforts to ‘model’ life, to grasp its singular properties and/or to unveil and demystify its seeming inaccessibility and mystery, are not just fascinating liminal, boundary, hybrid, crossover or go-between objects, while they are all of those of course. They also pose a direct challenge to some of our common conceptions about mechanism and embodiment. They challenge the simplicity of the distinction between a purported ‘mechanistic’ worldpicture, its ontology and its goals, and on the other hand (...) an attempt to understand ourselves and animals more broadly as flesh-and-blood, affective entities (that is, not just breathing and perspiring, but also desiring and ‘sanguine’ machines, as La Mettrie might have put it). In what follows I reflect on the complexity of early modern mechanism faced with the (living) body, and its mirror image, contemporary theories of embodiment. At times, embodiment theory seems to be governed by a fascination with what the Artificial Life researcher Ezequiel Di Paolo has called ‘biochauvinism’ (Di Paolo, “Extended Life”): an unquestioned belief that ‘living bodies are special’. Yet how does the theorist define this special status? The question is apparently a simple one, or at least promptly yields an aporia which appears simple: to borrow a provocative phrase from Terry Eagleton, embodiment theory is obsessed by the body but terrified of biology. Yet at the same time, at least since Hubert Dreyfus and Andy Clark’s groundbreaking works, embodiment has been a legit part of cognitive science, yielding the even more recently emerged field of ‘embodied cognition’ (see the work of Larry Shapiro), which seeks to depart from traditional cognitive science, especially the latter’s understanding of cognition as computational, in order to instead underscore “the significance of an organism’s body in how and what the organism thinks,” in Shapiro’s words.

The relations between life and cogntion have been addressed through different perspectives [Stewart 1996, Boden 2001, Bourgine and Stewart 2004, van Duijn & all 2006, Di Paolo 2009]. We would like here to address that subject by relating life to cognition through a process of meaning generation. Life emerged on earth as a far from thermodynamic equilibrium performance that had to maintain herself. Life is charactertized by a ‘stay alive’ constraint that has to be satisfied (such constraint can be (...) included in the constraint of being able to maintain far from equilibrium thermodynamic conditions [Bickhard 2011]). The local ‘stay alive‘ constraint has to be satisfied in an environment containing elements potentially supportive or harmfull. A key activity for the living entity is to characterize these elements in terms of meaningfulness relatively to the ‘stay alive’ constraint. This process can be modeled with an existing tool where a system submitted to an internal constraint generates meaningful information characterizing elements of the environment: the Meaning Generator System (MGS) [Menant, 2003, 2014 a]. In a few words: when a system submitted to an internal constraint receives from the environment an information that has a connection with the constraint it generates a meaning usable for the implementation of an action satisfying the constraint.The generated meaning is the connection existing between the received information and the constraint. The MGS models this process and interfaces to the action implementation for constraint satisfaction The meaning is generated by and for the system. The MGS grounds meaning generation in constraint satisfaction and links the living entity to her environment in a relational process. A simple example is with a paramecium close to a drop of acid. The paramecium which is submitted to a ‘stay alive’ constraint will move away from the acid area. The received information ‘presence of acid’ generates the meaning ‘acid not compatible with the ‘stay alive’ constraint‘ which triggers the moving away action (that example is close to Varela’s bacteria swimming up a sugar gradient. What the MGS brings in addition is a modeling of the significance of the chemical gradient for the organism). The action implemented to satisfy the constraint modifies the environment and the received information, establishing an interactive process linking the living entity to her environment. During its evolution animal life has elaborated new constraints (like ‘live group life’) and new functions enriching meaning generation and action scenarios. As a result the build up of meaningful representations has improved the constraint satisfaction processes of animals, embedding them in their environments in relational and interactive terms [Menant, 2011]. Cognition can be defined by proposing that ‘a system is cognitive if and only if sensory inputs serve to trigger actions in a specific way, so as to satisfy a viability constraint’ [Bourgine, Stewart 2004]. Cognition can also be considered as exemplifying a ‘vital criterion of responsiveness’ [Boden, 2001 ]. Consequently the MGS can be positioned as an elementary and generic version of animal cognition. For animal life, meaning generation for internal constraint satisfaction links life and cognition in a relational and interactive process. Cognition for human life is more complex as new performances have to be taken into account like self-consciousness and free-will. Meaning generation at human level is a challenging subject as human constraints are not clearly understood [Menant, 2011]. Many research activities are in process looking for some understanding of human mind [Philpapers]. One area of investigation is an evolutionary approach to self-consciousness using meaning generation where anxiety limitation comes up as a generic human constraint [Menant, 2014 b]. Assuming that we can have clear enough an understanding of some human constraints, we can look at the MGS for partly extending to humans the link between life and cognition that has been established for animals. So overall, we can consider that the MGS approach makes available an evolutionary link between life and cognition for animals, and partly for humans. A characteristic of the proposed system approach to meaning generation is the possibility to use it for any type of agent, be it organic (with intrinsic constraints ) or artificial (with derived constraints). Such characterization of agents through meaning generation can be used to discriminate artificial itelligence from human intelligence (see the MGS usage to support Searle’s chinese room argument [Menant, 2013]). On a more general basis, the proposed system approach can positions the MGS as a simple model for an internal source of normativity. It’s usage as a simple building block allows a bottom-up modeling for normativity in the sensorimotor approach. The ‘stay alive’ constraint could also be taken as a starting point for an evolutionary grounding of sensorimotor norms ‘in the biological normativity of the agent as a whole’ [Di Paolo & all 2014]. The proposed presentation will develop the points summarized here above and position them relatively to the autopoietic and enactive approaches. Several possible continuations will also be highlighted. (shrink)

In this chapter, the frameworks of enactive cognitive science (e.g., Baran- diaran 2008, 2017; Di Paolo et al. 2018) and ontological design, particu- larly the work of Tony Fry (e.g., 2009), are synthesized to give a general account of how humans act toward change at multiple scales. According to this synthesis, design is understood as a spatiotemporally extended form of adaptive self-regulation, or adaptivity in the enactive vocabulary (Di Paolo 2005). When we design, we regulate ourselves in the (...) local-present to resource our future selves in ways that make certain regulations either possible or easier, and thus, desired outcomes more probable. Adaptivity, here, entails an ongoing redirection of the individuating tendencies of person-world systems either for maintaining some existing trajectories or for stabilizing new ones. This happens predominantly through modify- ing constraints at what Secchi and Cowley (2018, 2021) term the meso- scale of social organizing. This chapter considers diferent types of design (maintenance, habit, identity) operative across scales, from organisms to organizations. It concludes with some indications for how this perspective might be valuable in facing current ecological and environmental chal- lenges and the obvious demands they put on the need for change across all scales of human living.

The notions of information, representation and enaction entertain historical and complex relations with cognition. Historical relations because representational structures belong to the central hypothesis of cognitive sciences. Complex relations because cognitive sciences apply the notion of representation to animals, humans and robots, and also because the enactive approach tends to disregard the GOFAI type of representations. In this wide horizon of relations, we propose to look at a systemic approach that could bring up a common denominator for information and representations (...) in the build up of cognition, and also keep a link with the enactive approach. Our purpose is to show that systems submitted to constraints can generate meaningful information to maintain their natures, and consequently build up meaningful representations that have some compatibility with the enactive approach. Such a systemic approach to the notion of meaningful information could then make available a link between enaction and meaningful representations. The first part of the presentation is about reminding that cognition does not exist per se, but is related to the system that builds it. We look at cognition as constituted by dynamic meaningful representations built up by systems that have constraints to satisfy in their environments. Cognition is considered here at the level of the system that builds it and uses it in order to maintain its nature in its environment. Such a systemic approach fits with evolution. Organisms build representations to cope with survival constraints (frogs build representations of moving black dots in order to satisfy food constraints). Humans build representations and cognition to satisfy constraints that are conscious and unconscious. Artificial systems can use representations and cognition to run activities related to constraints implemented by the designers or coming from the environment (a goal to reach being considered as a constraint to satisfy). In the second part of the presentation we define what are a meaningful information and a representation for a system submitted to a constraint in its environment, and we link these to the enactive approach. We define a meaningful information (a meaning) as an information generated by a system submitted to a constraint when it receives an external information that has a connection with the constraint. The meaning is precisely that connection. The meaning belongs to the interactions that link the system to its environment. The function of the meaning is to participate to the determination of an action that will be implemented in order to satisfy the constraint. (Menant, 2003). The satisfaction of the constraint goes with maintaining the nature of the system in its environment. A Meaning Generator System (MGS) is defined correspondingly. It is a building block for higher level systems. We present some characteristics of the MGS (groundings of a meaning, domain of efficiency and transfer of meanings, networking of meanings, evolutionary usage). The MGS approach is close to a simplified version of the Peircean triadic theory of signs (Menant, 2003, 2005 ). We define the representation of an item for a system as being the dynamic set of meaningful information corresponding to the item for the system in its environments (an elementary representation being made of a single meaningful information). These representations link the system to its environment by their meaningful components related to the nature of the system. These representations are different from the GOFAI ones. The possibilities for linking these notions of meaning and representation with the enactive approach come from the structure of the MGS: the need for an action is the cause of the meaning generation by and for the system. The action on the environment is for the system to maintain its nature (its identity). The MGS links together the generation of meaningful representations, the nature of the system, and the interactions with the environment. This can be considered as close to enacting a world by meaning generation (Di Paolo and all 2007), and to the enactive concept of sense making (De Jaegher, Di Paolo 2007). We propose that basing the definition of a representation on the notion of meaningful information generated by a system submitted to a constraint can open a way for making the notion of representation compatible with the enactive approach. In the third part of the presentation, we consider some cases of meaningful information and representations for organisms and for robots. Regarding organisms, the MGS can be used in an evolutionary context by looking at the evolution of the systems and of the constraints. Purpose is to modelize the generation of meanings and of representations in order to make available a tool usable for different levels of evolution, as evolution has a place in cognitive sciences (Proust, 2007). Constraints for basic life are survival constraints (individual and species). Group life constraints are also to be considered. Reaching the level of humans in evolution brings in new constraints that cannot be clearly identified as they have to take into account human consciousness which is today a mystery (the “hard problem”). On an evolutionary standpoint, human constraints come in addition to the ones existing for non human organisms. We can make some hypothesis on the nature of human constraints (Maslow pyramid based constraints, anxiety limitation…). For robots, the MGS is initially based on the design of the robot. The meaning generated within a robot is initially derived from the constraints implemented by the designer and from the environment. But some non calculable or non predictable evolutions of the robot can introduce meanings that look proper to the robot. This last point can be linked to the notion of autonomy in robots. In such examples, the dynamic management of meanings thru the MGSs in their environments keeps the link with the enactive approach. We finish the presentation by summarising the points addressed and by proposing several continuations. (shrink)

As he recalls in his book Naive Physics, Paolo Bozzi’s experiments on naïve or phenomenological physics were partly inspired by Aristotle’s spokesman Simplicio in Galileo’s Dialogue. Aristotle’s ‘naïve’ views of physical reality reflect the ways in which we are disposed perceptually to organize the physical reality we see. In what follows I want to apply this idea to the notion of a group, a term which I shall apply as an umbrella expression embracing ordinary visible collections (of pieces of (...) fruit in the fruit bowl), but also families, populations, kinds, categories, species and genera. I will try to determine to what extent we can understand what groups, in this broad sense, have in common and how they are distinguished from two sorts of entities with which they are standardly confused, namely sets and wholes.

Basilio Sabazio was the first in Italy to argue for the unity and corruptibility of either sublunar or celestial matter. In this paper new insight of his intellectual activity between Napoli and Milano is provided, and in particular his relationship with Scipione Capece, from whose letter to Giovan Francesco di Capua, Count of Palena we learn that Sabazio was an expert in philology and astronomy. The surviving part of an essay by Sabazio to the astronomer Francesco Cigalini from Como is (...) here edited with some informations about Cigalini’s reply. A newly recovered Sabazio’s astronomical work is here edited – from which his endorsement of Eraclides Ponticus’ astronomical system is evident –, as well as his Consilium to Pope Paolo III about the urgency of convening a general council.

Brano tratto dal libro di Guido del Giudice “Io dirò la verità”. Intervista a Giordano Bruno.

This paper presents a reconstruction of and some constructive comments on Thomas Pogge’s conception of global justice. Using Imre Lakatos’s notion of a research program, the paper identifies Pogge’s “hard core” and “protective belt” claims regarding the scope of fundamental principles of justice, the object and structure of duties of global justice, the explanation of world poverty, and the appropriate reforms to the existing global order. The paper recommends some amendments to Pogge’s program in each of the four areas.

Recent crises in Europe and beyond have renewed a longstanding debate on the status and treatment of refugees. Hannah Arendt famously questioned the limits of universalistic human rights discourse based on the widespread phenomena of statelessness and displacement that emerged during and after World War II. In this paper, we analyze recent patterns of inclusion and exclusion of refugees in Italy through the lens of Arendtian narrative and theorizing. We consider three cases of interaction between families, schools, and other public (...) institutions in light of the shifting normative framework before and during the war in Ukraine. Two major insights emerge from this analysis. From a pedagogical point of view, the most promising educational practices with refugees are those centered on enabling their agency and corresponding experiences of "natality". From an ethical-political perspective, these practices highlight a latent tension between the universalistic scope of human rights enshrined in the human rights declarations and their structural dependence on the particular norms and procedures enacted by nation states. The understanding and teaching of human rights within our political communities is inseparable from the practices that engage with refugees. In this sense, our practices of inclusion and exclusion affect the understanding of national borders as a barrier or threshold with other political communities, but also the interpretation of our own ethical-political principles.

It is common in political theory and practice to challenge normatively ambitious proposals by saying that their fulfillment is not feasible. But there has been insufficient conceptual exploration of what feasibility is, and very little substantive inquiry into why and how it matters for thinking about social justice. This paper provides one of the first systematic treatments of these issues, and proposes a dynamic approach to the relation between justice and feasibility that illuminates the importance of political imagination and dynamic (...) duties to expand agents’ power to fulfill ambitious principles of justice.

The literature on indicative conditionals contains two appealing views. The first is the selectional view: on this view, conditionals operate by selecting a single possibility, which is used to evaluate the consequent. The second is the informational view: on this view, conditionals don’t express propositions, but rather impose constraints on information states of speakers. Both views are supported by strong arguments, but they are incompatible on their standard formulations. Hence it appears that we have to choose between mutually exclusive options. (...) But the options are not exclusive. This paper develops a theory of the semantics and assertability of conditionals that is both selectional and informational. The theory vindicates the signature inferences of both selectional and informational theories, including so-called Conditionals Excluded Middle and principles about the interplay between conditionals and ‘might’. It also predicts some interesting and puzzling facts about the assertion of conditionals. (shrink)

This paper offers an exploration of the socialist principle “From each according to their abilities, to each according to their needs.” The Abilities/Needs Principle is arguably the ethical heart of socialism but, surprisingly, has received almost no attention by political philosophers. I propose an interpretation of the principle and argue that it involves appealing ideas of solidarity, fair reciprocity, recognition of individual differences, and meaningful work. The paper proceeds as follows. First, I analyze Marx’s formulation of the Abilities/Needs Principle. Second, (...) I identify the principle’s initial plausibility, but show that it faces serious problems that cannot be addressed without developing a fresh interpretation of it. Third, I provide an interpretation of the principle that highlights demands concerning opportunities for self-realization in work, positive duties of solidarity, sensitivity to individual differences, and mechanisms of fair reciprocity. Fourth, I discuss a possible institutional implementation of the Abilities/Needs Principle. Finally, I identify some normative puzzles about the transition from capitalism to socialism, and suggest how the Abilities/Needs Principle might gain motivational traction by mobilizing the powerful idea of human dignity.

It’s a common assumption in psychiatry and psychotherapy that mental health conditions are marked out by some form of epistemic irrationality. With respect to obsessive-compulsive disorder (OCD), the mainstream view is that OCD causes irrational beliefs. Recently, however, this ‘doxastic view’ has been criticized from a theoretical and empirical perspective. Instead a more promising ‘zetetic view’ has been proposed which locates the epistemic irrationality of OCD not in irrational beliefs, but in the senseless inquiries it prompts. Yet, in this paper (...) I present a special class of cases—sexual obsessive-compulsive disorder (S-OCD)—which cannot be explained by existing doxastic and zetetic accounts of the epistemic irrationality of OCD. In addition, some people with S-OCD appear to be adhering too well to a plausible set of norms for inquiry. Their suffering seems to be partially caused by an excess of rationality, and not a lack thereof. They seem, if anything, too rational. This shows firstly that it’s unlikely that there is one form of epistemic irrationality common to all persons living with OCD. Secondly, it should lead us to rethink the epistemic categories we use in classifying mental health conditions such as OCD. (shrink)

This paper explores the connections between human rights, human dignity, and power. The idea of human dignity is omnipresent in human rights discourse, but its meaning and point is not always clear. It is standardly used in two ways, to refer to a normative status of persons that makes their treatment in terms of human rights a proper response, and a social condition of persons in which their human rights are fulfilled. This paper pursues three tasks. First, it provides an (...) analysis of the content and an interpretation of the role of the idea of human dignity in current human rights discourse. The interpretation includes a pluralist view of human interests and dignity that avoids a narrow focus on rational agency. Second, this paper characterizes the two aspects of human dignity in terms of capabilities. Certain general human capabilities are among the facts that ground status-dignity, and the presence of certain more specific capabilities constitutes condition-dignity. Finally, this paper explores how the pursuit of human rights and human dignity links to distributions and uses of power. Since capabilities are a form of power, and human rights are in part aimed at respecting and promoting capabilities, human rights involve empowerment. Exploring the connections between human rights, capabilities, and empowerment provides resources to defend controversial human rights such as the right to democratic political participation, and to respond to worries about the feasibility of their fulfillment. This paper also argues that empowerment must be coupled with solidaristic concern in order to respond to unavoidable facts of social dependency and vulnerability. (shrink)

The period from 1900 to 1935 was particularly fruitful and important for the development of logic and logical metatheory. This survey is organized along eight "itineraries" concentrating on historically and conceptually linked strands in this development. Itinerary I deals with the evolution of conceptions of axiomatics. Itinerary II centers on the logical work of Bertrand Russell. Itinerary III presents the development of set theory from Zermelo onward. Itinerary IV discusses the contributions of the algebra of logic tradition, in particular, Löwenheim (...) and Skolem. Itinerary V surveys the work in logic connected to the Hilbert school, and itinerary V deals specifically with consistency proofs and metamathematics, including the incompleteness theorems. Itinerary VII traces the development of intuitionistic and many-valued logics. Itinerary VIII surveys the development of semantical notions from the early work on axiomatics up to Tarski's work on truth. (shrink)

Large Language Models (LLMs) are generative AI systems capable of producing original texts based on inputs about topic and style provided in the form of prompts or questions. The introduction of the outputs of these systems into human discursive practices poses unprecedented moral and political questions. The article articulates an analysis of the moral status of these systems and their interactions with human interlocutors based on the Habermasian theory of communicative action. The analysis explores, among other things, Habermas's inquiries into (...) the analogy between human minds and computers, and into the status of atypical participants in the linguistic community such as genetically modified subjects and animals. Major conclusions are the LLMs seem to qualify as authors that originally participate in discursive practices but do display only a structurally derivative form of communicative competence and fail to meet the status of communicative agents. In this sense, while the contribution of AI writing systems in public discourse and deliberation can support the process of mutual understanding within the community of speakers, the human actors involved in the development, use, and diffusion of these systems share a collective responsibility for the disclosure of AI authorship and verification and adjudication of validity claims.

On an influential line of thinking tracing back to Ramsey, conditionals are closely linked to the attitude of supposition. When applied to counterfactuals, this view suggests a subjunctive version of the so-called Ramsey test: the probability of a counterfactual If A, would B ought to be equivalent to the probability of B, under the subjunctive supposition that A. I present a collapse result for any view that endorses the subjunctive version of the Ramsey test. Starting from plausible assumptions, the result (...) shows that one’s rational credence in a would-counterfactual and in the corresponding might-counterfactual have to be identical. (shrink)

Supervaluationism is a well known theory of vagueness. Subvaluationism is a less well known theory of vagueness. But these theories cannot be taken apart, for they are in a relation of duality that can be made precise. This paper provides an introduction to the subvaluationist theory of vagueness in connection to its dual, supervaluationism. A survey on the supervaluationist theory can be found in the Compass paper of Keefe (2008); our presentation of the theory in this paper will be short (...) to get rapidly into the logical issues. This paper is relatively self-contained. A modest background on propositional modal logic is, though not strictly necessary, advisable. The reader might find useful the Compass papers Kracht (2011) and Negri (2011) (though these papers cover issues of more complexity than what is demanded to follow this paper). (shrink)

In this paper, I develop a quasi-transcendental argument to justify Kant’s infamous claim “man is evil by nature.” The cornerstone of my reconstruction lies in drawing a systematic distinction between the seemingly identical concepts of “evil disposition” (böseGesinnung) and “propensity to evil” (Hang zumBösen). The former, I argue, Kant reserves to describe the fundamental moral outlook of a single individual; the latter, the moral orientation of the whole species. Moreover, the appellative “evil” ranges over two different types of moral failure: (...) while an “evil disposition” is a failure to realize the good (i.e., to adopt the motive of duty as limiting condition for all one’s desires), an “evil propensity” is a failure to realize the highest good (i.e., to engage in the collective project of transforming the legal order into an ethical community). This correlation between units of moral analysis and types of obligation suggests a way to offer a deduction of the universal propensity on behalf of Kant. It consists in tracing the source of radical evil to the same subjective necessity that gives rise to the doctrine of the highest good. For, at the basis of Kant’s two doctrines lies the same natural dialectic between happiness and morality. While the highest good brings about the critically acceptable resolution of this dialectic, the propensity to evil perpetuates and aggravates it. Instead of connecting happiness and morality in an objective relation, the human will subordinatesmorality to the pursuit of happiness according to the subjective order of association. If this reading is correct, it would explain why prior attempts at a transcendental deduction have failed: interpreters have looked for the key to the deduction in the body of Kant’s text, where it is not to be found, for it is tucked, instead, in the Preface to the first edition.
