Exploring long-term educational change, we investigate our re/construction of research methodology as we moved from a positivist framework to working with ideas drawn from Deleuze and Guattari. We reveal our becoming rhizomatic in data analysis in the metamodelling of the richness flowing horizontally through our practices. We tell of our struggles to escape hierarchical thinking and relations researching between the smooth and striated. A space of interactions, conversations and writings created relations between polyphonic voices, leading us to an emergent methodology. (...) Our struggle against hierarchies in data analysis yielded rich educational possibilities for becoming that Deleuzo-Guattarian thinking offers us. (shrink)

The theory of the social responsibility of the firm oscillates between two extremes: one that reduces the firm's responsibility to the obtainment of (the greatest possible) profit for its shareholders, and another that extends the firm's responsibility to include a wide range of actors with an interest or "stake" in the firm. The stakeholder theory of the social responsibility of business is more appealing from an ethical point of view, and yet it lacks a solid foundation that would be acceptable (...) to a variety of schools of thought.In this paper I argue that the stakeholder theory could be founded on the concept of the common good. First, I explain the foundations of the theory of the common good, the concept itself, how it relates to the individual good, and its role in the firm. Following that, I explain how the theory of the common good could be applied to the stakeholder theory. Finally, I draw some conclusions. (shrink)

In this article we present an advanced version of Dual-PECCS, a cognitively-inspired knowledge representation and reasoning system aimed at extending the capabilities of artificial systems in conceptual categorization tasks. It combines different sorts of common-sense categorization (prototypical and exemplars-based categorization) with standard monotonic categorization procedures. These different types of inferential procedures are reconciled according to the tenets coming from the dual process theory of reasoning. On the other hand, from a representational perspective, the system relies on the hypothesis of conceptual (...) structures represented as heterogeneous proxytypes. Dual-PECCS has been experimentally assessed in a task of conceptual categorization where a target concept illustrated by a simple common-sense linguistic description had to be identified by resorting to a mix of categorization strategies, and its output has been compared to human responses. The obtained results suggest that our approach can be beneficial to improve the representational and reasoning conceptual capabilities of standard cognitive artificial systems, and –in addition– that it may be plausibly applied to different general computational models of cognition. The current version of the system, in fact, extends our previous work, in that Dual-PECCS is now integrated and tested into two cognitive architectures, ACT-R and CLARION, implementing different assumptions on the underlying invariant structures governing human cognition. Such integration allowed us to extend our previous evaluation. (shrink)

The proposal of moral enhancement as a valuable means to face the environmental, technological and social challenges that threaten the future of humanity has been criticized by a number of authors. One of the main criticisms has been that moral enhancement would diminish our freedom. It has been said that moral enhancement would lead enhanced people to lose their ‘freedom to fall’, that is, it would prevent them from being able to decide to carry out some morally bad actions, and (...) the possibility to desire and carry out these bad actions is an essential ingredient of free will, which would thus be limited or destroyed—or so the argument goes. In this paper we offer an answer to this criticism. We contend that a morally enhanced agent could lose the ‘freedom to fall’ without losing her freedom for two reasons. First, because we do not consider that a morally well-educated person, for whom the ‘freedom to fall’ is a remote option, is less free than an evildoer, and there is no reason to suppose that bioenhancement introduces a significant difference here. Second, because richness in the amount of alternative possibilities of action may be restored if the stated loss is compensated with an improvement in sensitivity and lucidity that can lead to seeing new options and nuances in the remaining possible actions.

Summary Robert Boyle did not subordinate chemistry to mechanical philosophy. He was in fact reluctant to explain chemical phenomena by having recourse to the mechanical properties of particles. For him chemistry provided a primary way of penetrating into nature. In his chemical works he employed corpuscles endowed with chemical properties as his explanans. Boyle's chemistry was corpuscular, rather than mechanical. As Boyle's views of seminal principles show, his corpuscular philosophy cannot be described as a purely mechanical theory of matter. Boyle's (...) classification of corpuscles allowed him to connect his corpuscular views of matter with chemistry. Boyle did not rule out the possibility of a classification of chemical substances based on their properties: his aim was to reform the received classification. (shrink)

In this paper we propose a computational framework aimed at extending the problem solving capabilities of cognitive artificial agents through the introduction of a novel, goal-directed, dynamic knowledge generation mechanism obtained via a non monotonic reasoning procedure. In particular, the proposed framework relies on the assumption that certain classes of problems cannot be solved by simply learning or injecting new external knowledge in the declarative memory of a cognitive artificial agent but, on the other hand, require a mechanism for the (...) automatic and creative re-framing, or re-formulation, of the available knowledge. We show how such mechanism can be obtained trough a framework of dynamic knowledge generation that is able to tackle the problem of commonsense concept combination. In addition, we show how such a framework can be employed in the field of cognitive architectures in order to overcome situations like the impasse in SOAR by extending the possible options of its subgoaling procedures.

During the last decades, many cognitive architectures (CAs) have been realized adopting different assumptions about the organization and the representation of their knowledge level. Some of them (e.g. SOAR [35]) adopt a classical symbolic approach, some (e.g. LEABRA[ 48]) are based on a purely connectionist model, while others (e.g. CLARION [59]) adopt a hybrid approach combining connectionist and symbolic representational levels. Additionally, some attempts (e.g. biSOAR) trying to extend the representational capacities of CAs by integrating diagrammatical representations and reasoning are (...) also available [34]. In this paper we propose a reflection on the role that Conceptual Spaces, a framework developed by Peter G¨ardenfors [24] more than fifteen years ago, can play in the current development of the Knowledge Level in Cognitive Systems and Architectures. In particular, we claim that Conceptual Spaces offer a lingua franca that allows to unify and generalize many aspects of the symbolic, sub-symbolic and diagrammatic approaches (by overcoming some of their typical problems) and to integrate them on a common ground. In doing so we extend and detail some of the arguments explored by G¨ardenfors [23] for defending the need of a conceptual, intermediate, representation level between the symbolic and the sub-symbolic one. In particular we focus on the advantages offered by Conceptual Spaces (w.r.t. symbolic and sub-symbolic approaches) in dealing with the problem of compositionality of representations based on typicality traits. Additionally, we argue that Conceptual Spaces could offer a unifying framework for interpreting many kinds of diagrammatic and analogical representations. As a consequence, their adoption could also favor the integration of diagrammatical representation and reasoning in CAs. (shrink)

The cases of corruption reported by the media tend almost always to involve a private party (a citizen or a corporation) that pays, or promises to pay, money to a public party (a politician or a public official, for example) in order to obtain an advantage or avoid a disadvantage. Because of the harm it does to economic efficiency and growth, and because of its social, political and ethical consequences, private-to-public corruption has been widely studied. Private-to-private corruption, by contrast, has (...) been relatively neglected and only recently has started to receive the attention it deserves. The purpose of this paper is to offer some thoughts on the nature and importance of private-to-private corruption; the legal treatment it receives in some of the world''s leading countries; and the measures that companies can take to combat it, with special consideration of its ethical aspects.

Today, values hold a prominent place both in business ethics and in organization theory. However, there persists considerable confusion about what these values are and what role they play in these theories and, therefore, how they can be developed both within the individual and within the organization. Therefore, this paper seeks to define a conception of values based on a theory of human action that can provide a basis for an organization theory, and to propose a series of ideas about (...) how personal and organizational values can be fostered.

The paper introduces an extension of the proposal according to which conceptual representations in cognitive agents should be intended as heterogeneous proxytypes. The main contribution of this paper is in that it details how to reconcile, under a heterogeneous representational perspective, different theories of typicality about conceptual representation and reasoning. In particular, it provides a novel theoretical hypothesis - as well as a novel categorization algorithm called DELTA - showing how to integrate the representational and reasoning assumptions of the theory-theory (...) of concepts with the those ascribed to the prototype and exemplars-based theories.

In this article we aim to distinguish between the transhuman and posthuman condition, according to their anthropological, ontological, and ethical natures. We will show that the current historical moment can be considered the beginning of a transhuman civilisation, given that the characteristics of the transhuman are already present in today’s human being. We will show that a series of decisive limitations for belonging to the human condition are in the process of being transcended due to acquisition of attributes of divinity (...) that human beings do not currently possess: omnipotence, omnipresence , ex nihilo creation – starting from the divine creative ideation – and immortality. Humans are increasingly taking on the attributes of divinity in the process of human enhancements. We will discuss the ways in which technology allows the human to overcome these limitations, elevating humans past their current condition, in a process in which they gain technological transcendence. Excepting immortality, all other limitations, once exceeded, generate a transhuman condition. Immortality generates a posthuman condition, since it can only be obtained by modifying the human ontological status from that of a biological being to that of a resident being in informatics networks. In order to clarify this process, we will discuss the concepts of everlastingness and artificial life prolongation. (shrink)

The paper investigates the kind of dependence relation that best portrays Machian frame-dragging in general relativity. The question is tricky because frame-dragging relates local inertial frames to distant distributions of matter in a time-independent way, thus establishing some sort of non-local link between the two. For this reason, a plain causal interpretation of frame-dragging faces huge challenges. The paper will shed light on the issue by using a generalized structural equation model analysis in terms of manipulationist counterfactuals recently applied in (...) the context of metaphysical enquiry by Schaffer (2016) and Wilson (2017). The verdict of the analysis will be that frame-dragging is best understood in terms of a novel type of dependence relation that is half-way between causation and grounding. (shrink)

Paul Grice’s theory of meaning has been widely adopted as a starting point for investigating the evolutionary and developmental emergence of linguistic communication. In this picture, reasoning about complexes of intentions is a prerequisite for communicating effectively at the prelinguistic level, as well as for acquiring a natural language. We argue that this broadly ‘Gricean’ picture rests on an equivocation between theories of communication and theories of cognition, and that it leads to paradoxical or implausible claims about human psychology. We (...) defend an alternative conception of prelinguistic communication, inspired by Bart Geurts and based on the notion of commitment. Adopting a commitment-first approach makes it possible to avoid the pernicious equivocation, and it provides a better systematization of the key empirical findings. We develop our argument with respect to infants’ sensitivity to ‘ostensive signals’; infants’ pointing; and infants’ endorsement of normative attitudes in joint activities. Finally, adopting a commitment-first approach makes it possible to argue that sophisticated forms of psychological reasoning are enabled by the mastery of a rich natural language, rather than being a prerequisite for acquiring one.

In his famous 1982 paper, Allen Newell [22, 23] introduced the notion of knowledge level to indicate a level of analysis, and prediction, of the rational behavior of a cognitive arti cial agent. This analysis concerns the investigation about the availability of the agent knowledge, in order to pursue its own goals, and is based on the so-called Rationality Principle (an assumption according to which "an agent will use the knowledge it has of its environment to achieve its goals" [22, (...) p. 17]. By using the Newell's own words: "To treat a system at the knowledge level is to treat it as having some knowledge, some goals, and believing it will do whatever is within its power to attain its goals, in so far as its knowledge indicates" [22, p. 13]. In the last decades, the importance of the knowledge level has been historically and system- atically downsized by the research area in cognitive architectures (CAs), whose interests have been mainly focused on the analysis and the development of mechanisms and the processes governing human and (arti cial) cognition. The knowledge level in CAs, however, represents a crucial level of analysis for the development of such arti cial general systems and therefore deserves greater research attention [17]. In the following, we will discuss areas of broad agree- ment and outline the main problematic aspects that should be faced within a Common Model of Cognition [12]. Such aspects, departing from an analysis at the knowledge level, also clearly impact both lower (e.g. representational) and higher (e.g. social) levels. (shrink)

There are three types of solutions to the problems deriving from companies' ethical, social and environmental responsibilities: those based on regulation by an authority or agency; those deigned to create market incentives; and those that rely on self-regulation by companies themselves. In the specific field we are concerned with here, regulation has significant costs and drawbacks that make it particularly desirable that companies should set up their own ethical, social and environmental management systems or programmes. The purpose of this article (...) is twofold. On the one hand, it explains how implementing voluntary ethical, social and environmental management systems or programmes may help to develop and sustain ethical behaviour in organizations, overcoming the conflict between compulsory regulation and occasional ethical practices. On the other hand, it shows that conditions must be met for an ethical management programme to be effective. (shrink)

Edith Stein and Gerda Walther explain how community comes to be and how it is structured, but they do not develop significant accounts of how communities disintegrate or die, albeit they make passing allusions to how this may happen. I argue that what makes communities vulnerable to their possible demise, following both Stein’s and Walther’s social ontology, is the breakdown of the sense of the communal bond, that is, the failure of the community members’ ability to make sense of their (...) relationship to one another. Just as sense-making and sense-building can help give birth and meaning to communities, sense disintegration and the dying of the sense of a community bespeak a vulnerability that lies at the very core of all communities. In addition to the vulnerability of sense-making, I argue that the lived-body and habit also pose important challenges to the very possibility of community. (shrink)

die besagten Begriffe zunachst als synonyme Bezeichnungen fUr die Methode der Philosophie betrachtet werden konnen. Erst am Ende der Abhandlung zeichnet sich die Moglichkeit einer Bedeutungstren nung zwischen EpocM und Reduktion ab - allerdings nicht mehr ganz im Sinne HusserIs.

Ihrem eingeborenen Telos der Letztverantwortung hat die Philosophie nie gerecht werden konnen, obschon in ihrer Geschichte zu alIer Zeit ein Streben, eine intentio auf dieses ihr Ziel der absoluten Reinheit hin wirksam war. Diese intentio war stets die "Motivation", der "Ent wicklungstrieb" des philosophischen Denkens: "In einigen Philoso phien zeitweilig relativ befriedigt, und doch nie letztbefriedigt, wird die Philosophie zu immer neuen methodischen Besinnungen fortgetrieben; sie nimmt immer neue methodische Gestalten an und kommt dabei doch nie zu Ende.

Ethical dilemmas raised by the use of nanotechnology in medical practice can be viewed from several perspectives: religious spiritualist perspective, the perspective of human dignity (nanotechnologies can be thought of as an affront to human dignity), the issue of controversial choice. The article aims to expose some bioethical dilemmas in using synthetic biology and nanotechnologies. Nowadays is often brought into discussion the fact it is possible to appear in the future new human species resulted not via natural selection and evolution, (...) but through the demiurgic effect of technology development in areas such as: synthetic biology, genetics, neurobiology and neurosciences, prosthesis technology and not least of artificial intelligence research. We will also refer into this paper at the possible raised challenges to ethicists who are oriented towards an ethics of species. Those challenges are raised right from the dawn of a consciousness of species, a social construction generated by changes of the meaning of belonging to humanity. During our article we argue that medical technology, especially genetics, medical assisted human reproduction and not least synthetic biology, require a rethinking ethical meanings of applying those technologies in everyday practices.

En este artículo nos proponemos exponer, a partir de los límites conceptuales encontrados a los planteamientos arqueo-genealógicos de Michel Foucault, la posibilidad de plantear, en dos momentos –arqueo-genealógico y gubernamental–, una “ética de la insubordinación reflexiva”. Es decir, una “ética de la libertad inmanente” al débil que al decir su palabra, denuncia y al denunciar cuestiona al tirano y su mundo al habar y actuar con –y por– los otros. Esta ética de la intersubjetividad planteada como una ética de la (...) insumisión concertada, crítica y deliberada, pensamos, puede derivar de ciertas “condiciones enunciativas” encontradas en las dos últimas investigaciones concernientes al “decir veraz” o el “hablar franco” expuestos en El gobierno de sí y de los otros (1982-1983) y El coraje de la verdad (1983-1984).

Appreciative approach to philosophy is based on the work of David Cooperrider on “Appreciative Inquiry”, which is a form of pragmatic discourse that substitutes the focus (...) on the problem with the focus on successful elements of previous experience of individuals, groups, organizations or communities. This experience can be integrated in the philosophical discourse starting from Plato's dialogues and maieutic method promoted by Socrates. Hermeneutic of the real seen as a philosophical reflection on the daily positive experiences falls into tradition of philosophical search of the ultimate meaning of reality. The appreciative speech starts from a postmodern view by a constructivist and constructionist approach, through which reality itself is a social construction generated by successive negotiations on accepted interpretations. Appreciative philosophy is centered on a semiotics grid that seeks positive qualities of existence and its strengths. Appreciative theology reveals a collaborative process between humanity and divine that catalyzes transformations in human being giving them life including eternal life. The communion human-Divinity is seen as a divine-human co-creation. (shrink)

One of the most interesting aspects of Leibniz's philosophy is the distinction between "art" and "nature"; the core of this matter is the possibility (or even the impossibility) of distinguishing as clearly as possible between two ontological domains: on one hand the products of technique (such as "artificial machines"), on the other hand all the beings that can be defined as natural ("natural machines"). The question raised in this paper is if it is possibile to build ontological criteria which can (...) be clear enough to distinguish between the products of nature and those of technique in the field of the "res" that they are.

ArgumentThis article argues that during the seventeenth century chemistry achieved intellectual and institutional recognition, starting its transition from a practical art – subordinated to medicine – into an independent discipline. This process was by no means a smooth one, as it took place amidst polemics and conflicts lasting more than a century. It began when Andreas Libavius endeavored to turn chemistry into a teaching discipline, imposing method and order. Chemistry underwent harsh criticism from Descartes and the Cartesians, who reduced natural (...) phenomena to the mechanical affections of matter, leaving little room for chemistry as an independent discipline. Boyle rejected the chemical principles and promoted the fusion of chemistry with corpuscularianism. He did not reduce chemical phenomena to the mechanical affections of matter, but strived to promote chemistry as part of natural philosophy. Lemery gave strong impulse to the recognition of chemistry as a discipline in its own right by fostering a compromise of chemistry and mechanism. Lemery adopted the chemical principles, but did not see them as the ultimate ingredients of bodies. In order to promote chemistry, he distanced it from alchemy and pursued the reform of chemical terminology. (shrink)

This paper is the result of the research I undertook at Lancaster University with a Marie Curie Fellowship during the academic years 2000‐2002. The objective of this research was to study the limits and the challenges of the analogy between molecular geneticists’ work and hackers’ activities. By focusing on this analogy I aim to explore the different ethical and philosophical issues surrounding new genetics and its IPR regulations. The paper firstly will show the philosophical background lying behind the proposed analogy (...) and analyses the sense in which we can talk of geneticists as “hackers.” It will provide grounds for the analogy by exploring some of the techniques used by geneticists; in particular it will focus on the so‐called Shotgun method for genomic sequencing. After having provided reasons for the proposed analogy I will claim that the open source philosophy used in the computer field would be a good way to regulate research in the genetics and in pharmaceutical field too. The open source philosophy would provide fair distribution of research opportunities around the globe with the shift from patenting to copyright in sensitive fields such as genetics. (shrink)

In 1964, the young Walter Kasper (born in 1933) was granted by the Faculty of Catholic Theology at Tübingen the licence to teach dogmatic theology on the basis of a thesis on Philosophie und Theologie der Geschichte in der Spätphilosophie Schellings (Philosophy and Theology of History in Schelling’s Late Philosophy). Kasper’s interest in Schelling, himself a student at the Evangelisches Stift at Tübingen, thus originated in the context of his university studies in the school of J.R. Geiselmann and developed in (...) parallel with his theological education. For this reason, it is impossible to form a correct idea of Kasper and his whole theology unless one is willing to take into account this background, not least because he himself has always consciously and forcefully recognised this fact and seen in it his own centre of gravity. Kasper’s work and thought were shaped in a lasting manner during his university years. In fact, his entire academic oeuvre has been nurtured from this fecund origin so much so that he became one of the most well known names associated with the Catholic school at Tübingen to which he gave a new, creative impulse having himself been profoundly inspired by it. ‘He always emphasised his own roots not only as a teacher of theology and a member of the teaching faculty of this institution, but also as bishop’ and cardinal. The principal intention of the present article is precisely this: to return to this beginning and elucidate these decisive years for Kasper in broad outline by way of a relecture and interpretation of his book on The Absolute in History and the particular manner in which he interpreted the so-called second Schelling, an author whom he approached in the wake of Walter Schulz and at practically the same time as Xavier Tilliette. The analysis will subsequently move on into the more properly theological field. (shrink)

El rápido desarrollo de las biotecnologías y el enorme potencial que encierran han hecho albergar la esperanza de la pronta aplicación de algunos avances técnicos al mejoramiento genético de los seres humanos. Ello ha propiciado la elaboración de numerosos análisis filosóficos centrados en cuestiones éticas y en las previsibles consecuencias, tanto positivas como negativas, de dicha aplicación. Una lectura de esta cuestión a través de la filosofía de la técnica de Ortega y Gasset nos permite apreciar, sin embargo, la importancia (...) de dos aspectos que han sido menos atendidos. Por un lado, es necesario realizar un análisis en profundidad de los motivos que llevan a desear la radical transformación del ser humano mediante la tecnología y de los intereses que hay detrás de ellos. Por otro lado, es injusta la identificación de la crítica al mejoramiento radical que trate de establecer ciertos límites con una posición bioconservadora y tecnofóbica que rechaza cualquier tipo de mejoramiento genético.

Aim of this work is to dispel the myth of the "vagueness" of naturalism. Between the Thirties and the Forties, naturalism moves “from old Europe to dynamic America” (as the historian Larrabee said). The controversy with visionary and fascist European theories was indeed very strong in the academic culture of the Thirties and Forties. The idea was to oppose to the former the virtue of a liberal democracy, supported by the liberality of the scientific method.In short, the cultural fight was (...) between naturalism and metaphysics (considered as theology). Naturalizing the "spirit" was the great ambition of American naturalistic programs of the Forties. They culminated with the publication of the ideological manifesto “Naturalism and the Human Spirit” (New York, 1944), edited by the John Dewey's group of Columbia. From Ernest Nagel to Sydney Hook, Roy Wood Sellars, William Sheldon and Arthur E. Murphy, all prominent American philosophers took part, in one way or another, to the naturalistic project. This latter aimed to be more than a simple "doctrine", by presenting itself as an expression of a new “mental attitude”, a fresh way of considering traditional unsolved problems. All this lead to the production of a new form of rhetoric, which in turn carried with itself a hidden ideology. Objective rationality embodied by scientific procedures became the totem to play against everything that would present itself as “just-subjective”, metaphysical, all-encompassing. A new idea of philosophy began to emerge, one that was less metaphysical, more humanistic and democratic, and concerned itself with “restricted, but manageable questions” (E. Nagel). (shrink)

The research in Human Computer Interaction (HCI) has nowadays extended its attention to the study of persuasive technologies. Following this line of research, in this paper we focus on websites and mobile applications in the e-commerce domain. In particular, we take them as an evident example of persuasive technologies. Starting from the hypothesis that there is a strong connection between logical fallacies, i.e., forms of reasoning which are logically invalid but psychologically persuasive, and some common persuasion strategies adopted within these (...) technological artifacts, we carried out a survey on a sample of 175 websites and 101 mobile applications. This survey was aimed at empirically evaluating the significance of this connection by detecting the use of persuasion techniques, based on logical fallacies, in existing websites and mobile apps. In addition, with the goal of assessing the effectiveness of different fallacy-based persuasion techniques, we performed an empirical evaluation where participants interacted with a persuasive (fallacy-based) and with a non-persuasive version of an e-commerce website. Our results show that fallacy-based persuasion strategies are extensively used in existing digital artifacts, and that they are actually effective in influencing users’ behavior, with strategies based on visual salience manipulation (accent fallacy) being both the most popular and the most effective ones.
