ABSTRACT This article studies the theory of animal seeds as purely material entities in the early seventeenth-century medical writings of Antonio Ponce Santacruz, royal physician to the Spanish king Philipp IV. Santacruz adopts the theory of the eduction of substantial forms from the potentiality of matter, according to which new kinds of causal powers can arise out of material composites of a certain complexity. Santacruz stands out among the late Aristotelian defenders of eduction theory because he applies the (...) concept of an instrument of direction developed by the medieval Avicenna commentator Gentile da Foligno and gives a novel turn to this concept by interpreting animal seeds as separate instruments. The article situates Santacruz's theory in the context of early modern debates about the concept of the eduction of forms, as well as in the context of early modern debates about the concept of separate instruments. Particular attention is paid to Santacruz's responses to the biological views of Julius Caesar Scaliger and Thomas Feyens. Santacruz's response to Scaliger turns out to be central for his explication of the eduction relation, and Santacruz's response to Feyens turns out to be central for his explication of the nature of instrumental causation.

Stoicism deserves everything that Broic$ are doing to its movement. This is because Stoics stuff the value of everything into their own heads, thus denying that external things are good and that other people have intrinsic value. Stoics are psychopathic narcissists and axiological solipsists. And this makes Stoicism easy to coopt into bro-y, shallow, self-help-y garbage.

Emil Cioran offers novel arguments against suicide. He assumes a meaningless world. But in such a world, he argues, suicide and death would be equally as meaningless as life or anything else. Suicide and death are as cumbersome and useless as meaning and life. Yet Cioran also argues that we should contemplate suicide to live better lives. By contemplating suicide, we confront the deep suffering inherent in existence. This humbles us enough to allow us to change even the deepest aspects (...) of ourselves. Yet it also reminds us that our peculiar human ability—being able to contemplate suicide—sets us above anything else in nature or in the heavens. This paper assembles and defends a view of suicide written about in Cioran’s aphorisms and essays. (shrink)

This paper aims to establish the importance of mathematical thinking in the work of Vilém Flusser. For this purpose highlights the concept of escalation of abstraction with which the Czech German philosopher finishes by reversing the top of the traditional pyramid of knowledge, we know from Plato and Aristotle. It also assumes the implicit cultural revolution in the refinement of the numerical element in a process of gradual abandonment of purely alphabetic code, highlights the new key code, together with the (...) technological and telematic culture and uses the concepts of game theory, of probability theory and computing to analize the society and culture. Of particular importance is the affirmation of a new kind of imagination, a projective one, ranging from the model to the world. Today's society and culture can´t be understood without resorting to the concepts and results coined and made ​​in the course of developing a type of thinking entirely dominated by the mathematics. The limits and boundaries of scientific disciplines overlap under number development, requiring reflection and rethinking traditional concepts of social and natural sciences. (shrink)

El artículo presenta un análisis de cuatro temas centrales de Sen: su visión sobre el ser humano, la libertad individual, la evaluación moral y los derechos, y la igualdad. Con esto quiero mostrar que estas ideas no sólo son consistentes, sino que explican muchas de las reflexiones sobre temas sociales y económicos que lo han convertido en un referente en estas áreas. En las conclusiones presentaré una síntesis e interpretación de estas ideas fundamentales, mostrando cómo constituyen un núcleo filosófico y (...) qué relaciones mantienen entre ellas. Mi objetivo no es encasillarlo en algunas de las corrientes de filosofía actuales, sino destacar la solidez y pertinencia de su aporte filosófico, algo sumamente útil en un tiempo como el nuestro, deseoso de ideas frescas para los acuciantes problemas de siempre.

Este artículo quiere investigar el lugar que tienen los afectos en el modo de hacer filosofía en América Latina. Para esto, la investigación se centra en las reflexiones de un grupo de filósofos que se autodenomina Equipo Jesuita de Reflexión Filosófica de América Latina, activo desde 1981. Utilizaré textos de su primera etapa cuando el equipo quiso expresamente reflexionar sobre una filosofía propia de América Latina, proyecto que denomina “filosofía inculturada”. Espero mostrar que las reflexiones de este grupo abordan tanto (...) el acto integral del filosofar como el pensamiento filosófico teórico. En el primer sentido, propone una “deontología del filósofo latinoamericano” cuyo método incluye como uno de sus pasos esenciales el “dejarse afectar” por la realidad según el principio de la simpatía, el cual generará otros sentimientos o afectos respecto a la realidad como encuadre para el filosofar. Pero el equipo no deja muy en claro la relación entre afectos y compromiso: ¿quién precede a quién? (shrink)

Aristotle argued that you need some wealth to live well. The Stoics argued that you could live well with or without wealth. But the Cynics argued that wealth is a hinderance. For the Cynics, a good life consists in self-sufficiency, or being able to rule and help yourself. You accomplish this by living simply and naturally, and by subjecting yourself to rigorous philosophical exercises. Cynics confronted people to get them to abandon extraneous possessions and positions of power to live better. (...) And while the Cynics were experts in living in this way, their ascetic lifestyles made their message curious to some audiences. This paper reflects on Cynic ascetic practices and the ways others perceived them. (shrink)

En el pensamiento de Santo Tomás de Aquino, la Filosofía Moral y la Teología Moral tienen al bien como concepto central, es decir, el ser en cuanto apetecible y en cuanto fin de la tendencia o apetito. Lo anterior es debido a que lo bueno expresa el en cuanto se relaciona con el apetito y de este modo señala la capacidad del ser para mover la voluntad o una tendencia cualquiera hacia su fin. Es por esto que Santo Tomás sostiene (...) con Aristóteles que el bien coincide con la noción de fin. Y es por la importancia de estos principios y por la repercusión en la moral y sobretodo en la explicación de la libertad moral, que este breve trabajo consiste en una profundización en las relaciones entre el bien, el fin y la naturaleza y algunas de sus aplicaciones a lo que se conoce como tendencia natural o apetito natural y la tendencia libre que se refiere a la voluntad sobre todo a la voluntad de la persona humana. No se trata de un intento por presentar todas las conclusiones que de estos principios se siguen, lo cual correspondería a la Filosofía o a la Teología Moral, sino más bien de una profundización en los principios metafísicos, para asentar los cimientos del orden moral. -/- In the thought of St. Thomas Aquinas, both ethics and moral theology have as their central concept of the good, that is, of being insofar as it is desirable and insofar as it is the end of appetitive tendencies. This is due to the fact that the good expresses being insofar as it relates to the appetite, and thus it expresses the capacity of being to move the will, or to any tendency towards its end. For this reason St. Thomas holds with Aristotle that the good is convertible with the notion of end. And it is due tuo the importance of these principles and their consequences for morality and moral freedom that in this brief work I attempt to delve into the relationship between the good, the end, and nature, and some of its applications to what is known as natural tendency or natural appetite as well as to the free tendency which is called "the will", especially the will of the huma person. It is not an attempt to present all the conclusions that follow form these principles -a task that would correspond to ethics or to moral theology- but attempt to delve into the metaphysical principles that ground the moral order.

When considering the value of friendship, most philosophers ignore the negatives. Most assume that humans need friends to flourish, and some argue that friendships can be good, no matter the risks entailed. This makes conversations about the value of friendship one-sided. Here, I argue that Cynics and Pessimists have an important view on friendship, despite it being ignored. They hold that: (a) friendship is unnecessary for flourishing, and (b) friendship presents ethical risks, especially to one’s own self-sufficiency. I defend these (...) views. Then I conclude with reflections on why Cynics and Pessimists actually make great friends. By helping people to focus on vulgar human nature and the flaws that humans have, they create an unpretentious basis for friendship. (shrink)

We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of the combination of prototypical concepts. The proposed logic relies on the logic of typicality ALC + TR, whose semantics is based on the notion of rational closure, as well as on the distributed semantics of probabilistic Description Logics, and is equipped with a cognitive heuristic used by humans for concept composition. We first extend the logic of typicality ALC + TR by typicality inclusions of the (...) form p :: T(C) v D, whose intuitive meaning is that “we believe with degree p about the fact that typical Cs are Ds”. As in the distributed semantics, we define different scenarios containing only some typicality inclusions, each one having a suitable probability. We then exploit such scenarios in order to ascribe typical properties to a concept C obtained as the combination of two prototypical concepts. We also show that reasoning in the proposed Description Logic is EXPTIME-complete as for the underlying standard Description Logic ALC. (shrink)

La aspiración a formar sociedades justas se choca con alarmantes niveles de pobreza y desigualdad, un problema al cual toda reflexión sobre la justa sociedad debe ofrecer una respuesta convincente. Esta ponencia afirma (1ª parte) que la experiencia que tenemos de las injusticias – como la pobreza – puede dar origen a una reflexión sobre la justicia. Luego (2ª parte) presenta el concepto de pobreza según el enfoque de las capacidades de Amartya Sen y lo completa con una interpretación filosófica (...) de la pobreza como privación radical de libertad individual. Finalmente (3ª parte) analiza y critica la forma en que la teoría de la justicia de John Rawls no aborda el problema de la pobreza y propone un principio de justicia previo a los dos de Rawls – el principio “cero” – que recoge el desafío que la pobreza plantea al concepto de sociedad justa.

We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of combining prototypical concepts, an open problem in the fields of AI and cognitive modelling. Our logic extends the logic of typicality ALC + TR, based on the notion of rational closure, by inclusions p :: T(C) v D (“we have probability p that typical Cs are Ds”), coming from the distributed semantics of probabilistic Description Logics. Additionally, it embeds a set of cognitive heuristics for concept (...) combination. We show that the complexity of reasoning in our logic is EXPTIME-complete as in ALC. (shrink)

Cualquiera que sea la opinión que uno tenga sobre la participación de la Iglesia católica en los debates políticos del Ecuador, nadie negará que ha sido y sigue siendo un actor importante de estos debates. Conocer sus ideas políticas contribuye a entender mejor este rol y a juzgarlo con más fundamento y menos apasionamiento. Por esto, el actual volumen reúne textos selectos de cinco pensadores católicos ecuatorianos representativos, desde fines del siglo XIX hasta las últimas décadas del siglo XX. Hablamos (...) de: • Monseñor Federico González Suárez (1844 – 1917). Historiador, arqueólogo, Obispo de Ibarra (1895 – 1905) y Arzobispo de Quito (1906 – 1917). • Cardenal Carlos María de la Torre (1873 – 1968). Arzobispo de Quito (1933-1967) y Cardenal desde 1953. • Julio Tobar Donoso (1894 – 1981). Jurista, diplomático, historiador. • Cardenal Pablo Muñoz Vega (1903 – 1994). Arzobispo de Quito (1967- 1985) y Cardenal desde 1969. • Monseñor Leonidas Proaño (1910 – 1988). Obispo de Riobamba (1954-1985) y candidato al Premio Nobel de la Paz en 1986. El objetivo de esta publicación es ofrecer una síntesis coherente del pensamiento político de estos autores, a pesar de las diferencias que entre ellos existen. No ofrecemos una compilación sobre “el” pensamiento político católico, así dicho en general, porque sería exhaustivo y pretencioso. Nos limitaremos a presentar una síntesis que nos introduzca a las principales cuestiones sociales y políticas que han preocupado a estas cinco figuras. Este trabajo tiene naturalmente sus límites debidos al amplio espacio de tiempo considerado, las múltiples cuestiones políticas implicadas y la productividad de los autores, todos ellos pensadores a la vez que personas de acción.

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.

La pobreza y la democracia guardan relaciones complejas y ya bastante estudiadas por los científicos sociales. En este artículo no volveré sobre estos enfoques, ni tampoco insistiré en los problemas de gobernabilidad que nacen de la pobreza, sino que presentaré la crítica filosófico-política al ideal democrático que resulta cuando consideramos a la pobreza como privación de libertad individual. A la pobreza se la puede entender desde múltiples perspectivas filosóficas, pero el interpretarla como privación de libertad individual, como lo hace Amartya (...) Sen, la pone en relación directa y problemática con un sistema de gobierno que precisamente hace de las libertades, y de la libertad humana en general, su nervio central. Quisiera sostener que la existencia de la pobreza pone en duda que vivamos en sociedades democráticas porque cuestiona la finalidad y la esencia de estas comunidades, a la vez que les desafía a pensar cómo pueden convertirse realmente en sociedades justas. Comenzaré con una interpretación filosófica de la pobreza a partir de algunas ideas de Sen (sección 1). Seguiré con el análisis de la relación que se podría establecer entre la privación de libertad y la comunidad política según tres filósofos de la tradición occidental: Aristóteles, Baruch de Espinosa y John Locke (sección 2), y terminaré presentando tres desafíos que la pobreza presenta a nuestras democracias (sección 3).

This paper does two things. First, it interprets the work of W. E. B. Du Bois to reveal that the meanings of race terms are grounded by both a historical and an aspirational component. Race terms refer to a backward-looking component that traces the history of the group to its present time, as well as a forward-looking component that sets out values and goals for the group. Race terms thus refer to a complex cluster of concepts that involve biological, sociological, (...) historical, moral, and political properties. Second, the paper defends W. E. B. Du Bois’s conservationist thesis about races, which holds that we should maintain race talk and racial distinctions. But instead of offering philosophical evidence, this paper defends the plausibility of the conservationist thesis with evidence from contemporary biology and psychology. It argues that, instead of eliminating race terms or concepts, we should conserve and revise them. (shrink)

The open-question argument (OQA) is an argument in meta-ethics that is used against ethical naturalism, the thesis that moral properties are identical to natural properties. This argument has been rightfully criticized, and one notable criticism is that it overlooks the sense-reference distinction, viz. the distinction between the concept that a term refers to and the sense in which it is being used. Ayn Rand's Objectivism rejects the sense-reference distinction, and this paper will present an argument that uses the OQA to (...) argue against the underlying epistemological assumptions of Objectivism.

It bridges the gap between the theoretical, experimental and technological issues addressed in the context of AI of cognitive inspiration and computational cognitive science. -/- Beginning with an overview of the historical, methodological and technical issues in the field of Cognitively-Inspired Artificial Intelligence, (...) Lieto illustrates how the cognitive design approach has an important role to play in the development of intelligent AI technologies and plausible computational models of cognition. Introducing a unique perspective that draws upon Cybernetics and early AI principles, Lieto emphasizes the need for an equivalence between cognitive processes and implemented AI procedures, in order to realise biologically and cognitively inspired artificial minds. He also introduces the Minimal Cognitive Grid, a pragmatic method to rank the different degrees of biologically and cognitive accuracy of artificial systems in order project and predict their explanatory power with respect to the natural systems taken as source of inspiration. -/- Providing a comprehensive overview of cognitive design principles in constructing artificial minds, this text will be essential reading for students and researchers of artificial intelligence and cognitive science.

Algunos presupuestos teológicos de la crisis de Occidente Some theological presuppositions of the crisis of the West -/- Manuel Ocampo Ponce Universidad Panamericana Departamento de Humanidades -/- Resumen. Muchos hablan de una crisis en occidente y de los distintos factores que han contribuido a la misma. Sin embargo, no son tantos los que involucran los factores teológicos que han influido en dicha crisis. De aquí que el presente estudio sea un intento por presentar algunos de los presupuestos teológicos de (...) lo que se ha llamado “la crisis de occidente”. Se trata de presentar ciertas ideas filosóficas que han repercutido en las propuestas de algunos teólogos y pensadores del siglo XX y lo que va del XXI, y de demostrar que dichas ideas han producido cambios significativos en la concepción de Dios, en la concepción de las dimensiones personal y social del hombre, y con estas en la organización del mundo contribuyendo, en distintos niveles, lo que se ha denominado la crisis de Occidente. -/- Palabras clave: Dios, Cristianismo, ser, Teología, Metafísica, crisis, agnosticismo, relativismo, secularismo. -/- Abstract. Many speak of a crisis in the West and of the various factors that have contributed to it. However, few mention the theological factors that have influenced this crisis. Hence, the present study is an attempt to present some of the theological presuppositions of what has been called "the crisis of the West". The study presents certain philosophical ideas that have had repercussions on the proposals of some representative theologians of the twentieth and twenty-first centuries. It seeks to demonstrate that these ideas have produced some changes in the conception of God, in the conception of personal and social dimensions and in the organization of the world. These have favored, at different levels, what has been called the crisis of the West. -/- Key words: God, Christianism, being, Theology, Methaphisics, crisis, agnosticism, relativism, secularism. -/- En las últimas décadas se ha hablado mucho de que el mundo occidental se encuentra en crisis. Crisis de pensamiento, crisis de valores, crisis moral, crisis en los ámbitos científicos, artísticos, humanos, ambientales, etc. Sin embargo, es necesario aclarar que, para comprender Occidente y su crisis, es imprescindible considerar el papel del cristianismo como elemento fundamental de la cultura occidental. No podemos dejar de lado que, si el cristianismo tiene un peso en el desarrollo de Occidente, también debe tener un peso en sus logros y en sus decadencias y fracasos. En efecto, así como no podemos entender el mundo árabe si no conocemos el Islam, o Asia si no conocemos el budismo, tampoco podemos comprender Occidente si no conocemos el cristianismo. Esa es la razón por la que pensamos que cualquier análisis serio de la cultura de Occidente, ha de considerar el cristianismo como elemento clave para su comprensión. Pero hay que ser conscientes de que el cristianismo abarca muchos ámbitos especulativos y prácticos que, en una investigación de esta naturaleza, son imposibles de abarcar. Por lo mismo, el presente estudio se limita a mostrar de manera muy panorámica sólo algunos de los elementos teológicos de la crisis de Occidente que muchas veces son pasados por alto en distintos ámbitos, considerando que la Teología cristiana está conformada por una fuerte base filosófica. Como corolario de este estudio se deduce una solución que deviene de los mismos factores que han sido causas de la crisis. Se ha realizado una selección de algunos autores que he considerado como representativos de movimientos de pensamiento que han dado lugar a ciertos cambios importantes, y presentarlos demostrando el papel que ha tenido la modificación de la Teología cristiana en la crisis de Occidente.

In this paper we identify and characterize an analysis of two problematic aspects affecting the representational level of cognitive architectures (CAs), namely: the limited size and the homogeneous typology of the encoded and processed knowledge. We argue that such aspects may constitute not only a technological problem that, in our opinion, should be addressed in order to build arti cial agents able to exhibit intelligent behaviours in general scenarios, but also an epistemological one, since they limit the plausibility of the (...) comparison of the CAs' knowledge representation and processing mechanisms with those executed by humans in their everyday activities. In the fi nal part of the paper further directions of research will be explored, trying to address current limitations and future challenges. (shrink)

In actuarial parlance, the price of an insurance policy is considered fair if customers bearing the same risk are charged the same price. The estimate of this fair amount hinges on the expected value obtained by weighting the different claims by their probability. We argue that, historically, this concept of actuarial fairness originates in an Aristotelian principle of justice in exchange (equality in risk). We will examine how this principle was formalized in the 16th century and shaped in life insurance (...) during the following two hundred years, in two different interpretations. The Domatian account of actuarial fairness relied on subjective uncertainty: An agreement on risk was fair if both parties were equally ignorant about the chances of an uncertain event. The objectivist version grounded any agreement on an objective risk estimate drawn from a mortality table. We will show how the objectivist approach collapsed in the market for life annuities during the 18th century, leaving open the question of why we still speak of actuarial fairness as if it were an objective expected value. (shrink)

We defend, from a contractarian perspective, that the fair price of an insurance policy is the amount that the contracting parties agree when they are both equally uncertain about the insured event. Drawing on the approach developed by R. Sugden in _The Community of Advantage_, we answer two standard objections raised against contractarianism in the actuarial sciences: (1) people are not wise enough to assess their actuarial risks; (2) they are not rational enough to decide which insurance policy suits them (...) better. We show under which circumstances people can make fair actuarial agreements, without presupposing any objective risk or rationality benchmarks. (shrink)

The paper discusses from a metaphysical standpoint the nature of the dependence relation underpinning the talk of mutual action between material and spatiotemporal structures in general relativity. It is shown that the standard analyses of dependence in terms of causation or grounding are ill-suited for the general relativistic context. Instead, a non-standard analytical framework in terms of structural equation modeling is exploited, which leads to the conclusion that the kind of dependence encoded in the Einstein field equations is a novel (...) one.

This paper elaborates on relationalism about space and time as motivated by a minimalist ontology of the physical world: there are only matter points that are individuated by the distance relations among them, with these relations changing. We assess two strategies to combine this ontology with physics, using classical mechanics as example: the Humean strategy adopts the standard, non-relationalist physical theories as they stand and interprets their formal apparatus as the means of bookkeeping of the change of the distance relations (...) instead of committing us to additional elements of the ontology. The alternative theory strategy seeks to combine the relationalist ontology with a relationalist physical theory that reproduces the predictions of the standard theory in the domain where these are empirically tested. We show that, as things stand, this strategy cannot be accomplished without compromising a minimalist relationalist ontology. (shrink)

The goal of this essay is twofold. First, it provides a quick look at the foundations of modern relational mechanics by tracing its development from Julian Barbour and Bruno Bertotti's original ideas until present-day's pure shape dynamics. Secondly, it discusses the most appropriate metaphysics for pure shape dynamics, showing that relationalism is more of a nuanced thesis rather than an elusive one. The chapter ends with a brief assessment of the prospects of pure shape dynamics in light of quantum physics.

In this paper a possible general framework for the representation of concepts in cognitive artificial systems and cognitive architectures is proposed. The framework is inspired by the so called proxytype theory of concepts and combines it with the heterogeneity approach to concept representations, according to which concepts do not constitute a unitary phenomenon. The contribution of the paper is twofold: on one hand, it aims at providing a novel theoretical hypothesis for the debate about concepts in cognitive sciences by providing (...) unexplored connections between different theories; on the other hand it is aimed at sketching a computational characterization of the problem of concept representation in cognitively inspired artificial systems and in cognitive architectures.

Resumen: Es un hecho que Dios ha impreso de un modo necesario e indefectible la dirección hacia su fin a las creaturas materiales y a las creaturas espirituales incluido el caso concreto del hombre. Pero también es un hecho que en el mundo corpóreo, la persona humana cuenta con la libertad de los medios para alcanzar dicho fin. En esto se distingue el hombre de los animales irracionales, en que la naturaleza espiritual y libre ha de ser encauzada en su (...) actividad por una ley específicamente distinta a la del mundo irracional, que a la vez de conducirla eficazmente hacia su fin, sea compatible con la libertad. Dada la relevancia de este tema para la comprensión del problema moral del hombre, el objeto de este trabajo es profundizar en la naturaleza del acto libre y por ende en los principios que fundamentan la libertad en el pensamiento de Santo Tomás de Aquino quien sin lugar a duda ha logrado una gran profundidad en el análisis del acto humano. Palabras clave: acto - bien - felicidad - fin - libertad -/- Abstract: God has impressed upon both material and spiritual creatures, including the concrete case of man, a necessary and indefectible direction towards their end. But at the same time, in the corporeal world, the human person possesses a special freedom with regard to the means whereby to reach that end. This is precisely what distinguishes man from irrational animals: that our free and spiritual nature must be directed in its activity by a law specifically distinct from that of the irrational world, such that, while it drives us towards our end, it remains compatible with free will. Given the relevance of this theme for the understanding of the moral problem of the human person, the goal of this work is to delve more deeply into the nature of free human acts and therefore into the foundational principles of free will in the thought of St. Thomas Aquinas, who undoubtedly has offered a profound analysis of human acts.

The term attention has been used to mean so many different things that some have despaired of it being useful at all. This paper is devoted to bringing a modicum of order to the chaos through the time-honored device of categorization. The chief purpose of this paper is to introduce a comprehensive descriptive taxonomy of the nuanced ways the term attention may be employed. It is presented in table form, followed by elucidations and illustrations of each of its items. But (...) first, I offer reasons why a taxonomy of attention is needed and explore some of its possible benefits. After presenting the taxonomy, I sketch by way of example how it might be applied to two interesting questions: is the umbrella term attention still useful?; and, what is it that ties the subdefinitions of attention together yet distinguishes them from other kinds of cognition?

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 paper presents the heterogeneous proxytypes hypothesis as a cognitively-inspired computational framework able to reconcile, in both natural and artificial systems, different theories of typicality about conceptual representation and reasoning that have been traditionally seen as incompatible. In particular, through the Dual PECCS system and its evolution, it shows how prototypes, exemplars and theory-theory like conceptual representations can be integrated in a cognitive artificial agent (thus extending its categorization capabilities) and, in addition, can provide useful insights in the context of (...) a computationally grounded science of the mind.

In this paper we present a framework for the dynamic and automatic generation of novel knowledge obtained through a process of commonsense reasoning based on typicality-based concept combination. We exploit a recently introduced extension of a Description Logic of typicality able to combine prototypical descriptions of concepts in order to generate new prototypical concepts and deal with problem like the PET FISH (Osherson and Smith, 1981; Lieto & Pozzato, 2019). Intuitively, in the context of our application of this logic, the (...) overall pipeline of our system works as follows: given a goal expressed as a set of properties, if the knowledge base does not contain a concept able to fulfill all these properties, then our system looks for two concepts to recombine in order to extend the original knowledge based satisfy the goal. (shrink)

Commonsense reasoning is a crucial human ability employed in everyday tasks. In this talk I provide a knowledge level analysis of the main representational and reasoning problems affecting the cognitive architectures for what concerns this issue. In providing this analysis I will show, by considering some of the main cognitive architectures currently available (e.g. SOAR, ACT-R, CLARION), how one of the main problems of such architectures is represented by the fact that their knowledge representation and processing mechanisms are not sufficiently (...) constrained with insights coming from cognitive science (Lieto 2021; Lieto, Lebiere, Oltramari, 2018). As a possible way out to such knowledge processing issues, I present the main assumptions that have led to the development of the Dual PECCS categorization system (Lieto, Radicioni, Rho 2017) and discuss some of the lessons learned and their possible implications in the design of the knowledge modules and knowledge-processing mechanisms of integrated cognitive architectures.

Inventing novel knowledge to solve problems is a crucial, creative, mechanism employed by humans, to extend their range of action. In this talk, I will show how commonsense reasoning plays a crucial role in this respect. In particular, I will present a cognitively inspired reasoning framework for knowledge invention and creative problem solving exploiting TCL: a non-monotonic extension of a Description Logic (DL) of typicality able to combine prototypical (commonsense) descriptions of concepts in a human-like fashion. The proposed approach has (...) been tested both in the task of goal-driven concept invention and has additionally applied within the context of serendipity-based recommendation systems. I will present the obtained results, the lessons learned, and the road ahead of this research path. (shrink)

Resumen: Frente a la situación de ateísmo teórico y práctico que prevalece en este contexto, el presente trabajo es una síntesis de los fundamentos filosóficos sobre Dios que constituye el tema más importante de la Filosofía.

Es un intento por mostrar el brillo de la doctrina presentada por Santo Tomás de Aquino y por hacer ver que, a pesar de lo que haya podido decirse, la síntesis del Aquinate, acabada en sus principios y abierta en sus conclusiones, contiene un valor perenne que hasta el momento ha sido insuperable. Abstract: Faced with the situation of theoretical and practical atheism prevalent in this context, this paper is a synthesis of the philosophical foundations of God, which is the most important issue of philosophy. It is an effort to present synthetically and clearly everything related to the Being, the Existence, the Essence and the Divine perfections, and the fact that any being, any remaining in being and any growth of creatures is founded and is caused by God who is the Being in and of Himself, the first cause and the final cause of all that exists. It is an attempt to show the brilliance of the doctrine presented by St. Thomas Aquinas and to show that the synthesis of Aquinas, finished in its principles and open in its conclusions, contains a perennial value that, despite what has been said, has not yet been surpassed.

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.

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)

Abstract The present work is a metaphysical analysis of the relation between the intellect and the will, starting from the solution offered by Saint Thomas Aquinas to the intellectualist and voluntarist proposals of his time. Through the application of the doctrine of the act and power discovered by Aristotle, and with the important elements that Christianity had contributed by the thirteenth century, St. Thomas solves the problem of the production of universal concepts in an environment of concrete material realities. The (...) contribution of St. Thomas consists in having achieved a moderate intellectualism, granting each faculty the value and preeminence that corresponds to it, avoiding relativistic voluntarism and reaching a depth that is unique in metaphysical realism in the history of thought. Keywords Intellect – will – act – potential – intellectualism – voluntarism. (shrink)

Is attention both necessary and sufficient for consciousness? Call this central question of this treatise, “Q.” We commonly have the experience of consciously paying attention to something, but is it possible to be conscious of something you are not attending to, or to attend to something of which you are not conscious? Where might we find examples of these? This treatise is a quest to find an answer to Q in two parts. Part I reviews the foundations upon which the (...) discourse on Q is built. Different inputs to Q produce different answers. After consideration of the many ways “attention” and “consciousness” have been defined, I settle upon phenomenal consciousness and Executive Attention (defined as a suite of strategies for structuring cognition for further processing implemented by the executive of working memory) as the most interesting inputs to Q, and the ones on which Part II focuses. Attention without consciousness seems relatively easy to establish empirically, but consciousness without attention is much harder. The putative candidates all seem to have major problems, but I build a strong abductive case for the hitherto ignored case of foveal phenomenal overflow. We consciously see far more detail in our foveal fields than we can Executively Attend, although there is a serious obstacle to our ever confirming that empirically—identifying conscious content relies on Executive Attentional report. Triangulating the capacity limitations of attention, consciousness, and working memory strengthens this case for consciousness without attention, and suggests that cognition must work something like my “Witches’ Hat Model,” on which content can become conscious outside of Executive Attention or working memory. I conclude with some reflections on the implications of my arguments for the discourse on Q, and for other discourses such as the ontologies of attention and consciousness, theories of consciousness, some other cognitive concepts, and ethical considerations in humans, animals, and machines. A conclusive answer to Q continues to elude us. It may perhaps be an ultimately insoluble conundrum. But it is the very essence of humanity to seek an answer, and in so doing, to improve our understanding of our own nature: “The proper study of mankind is man.”1. (shrink)

Pure shape dynamics (PSD) is a novel implementation of the relational framework originally proposed by Julian Barbour and Bruno Bertotti. PSD represents a Leibnizian/Machian approach to physics in that it completely describes the dynamical evolution of a physical system without resorting to any structure external to the system itself. The chapter discusses how PSD effectively describes a de Broglie-Bohm N-body system and the conceptual benefits of such a relational description. The analysis will highlight the new directions in the quest for (...) an understanding of the nature of the wave function that are opened up by a modern relationalist elaboration on de Broglie's and Bohm's original insights.

In this paper, we argue that computer simulations can provide valuable insights into the performance of voting methods on different collective decision problems. This could improve institutional design, even when there is no general theoretical result to support the optimality of a voting method. To support our claim, we first describe a decision problem that has not received much theoretical attention in the literature. We outline different voting methods to address that collective decision problem. Under certain criteria of assessment akin (...) to extensions of the Condorcet Jury Theorem, we run simulations for the methods using MATLAB, in order to compare their performance under various conditions. We consider and respond to concerns about the use of simulations in the assessment of voting procedures for policymaking. (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)
