Category-based induction is an inferential mechanism that uses knowledge of conceptual relations in order to estimate how likely is for a property to be projected from one category to another. During the last decades, psychologists have identified several features of this mechanism, and they have proposed different formal models of it. In this article; we propose a new mathematical model for category-based induction based on distances on conceptual spaces. We show how this model can predict most of the properties of (...) this kind of reasoning while providing a solid theoretical foundation for it. We also show that it subsumes some of the previous models proposed in the literature and that it generates new predictions. (shrink)

In this paper, we outline a comprehensive approach to composed analogies based on the theory of conceptual spaces. Our algorithmic model understands analogy as a search procedure and builds upon the idea that analogical similarity depends on a conceptual phenomena called ‘dimensional salience.’ We distinguish between category-based, property-based, event-based, and part-whole analogies, and propose computationally-oriented methods for explicating them in terms of conceptual spaces.

Algunas de las preguntas fundamentales de la filosofía del arte son: 1) ¿Qué es una obra de arte?, 2) ¿Qué es Arte?, 3) ¿Qué es el arte? Responderlas es determinar el sentido del arte. Este tipo de preguntas están planteadas bajo la fórmula ¿Qué es X?, es decir, preguntas en las cuales en lo simple esta lo complejo, preguntas en donde lo simple no quiere decir que sean sencillas; son preguntas que traen dentro de si su naturaleza y carácter metafísico-ontológico-gnoseológico, (...) y hasta axiológico. No es el propósito de este trabajo hacer frente o resolver estos problemas, sino proporcionar una aproximación al concepto de “obra de arte” en la época actual y como podría entenderse en relación a ciertos problemas ontológicos y epistemológicos actuales. -/- [Extended Version of: Vélez León, Paulo (2006). «Aproximaciones a la ¿obra de arte?».

Autonomy has been central to moral and political philosophy for millenia, and has been positioned as a critical aspect of both justice and wellbeing. Research in psychology supports this position, providing empirical evidence that autonomy is critical to motivation, personal growth and psychological wellness. Responsible AI will require an understanding of, and ability to effectively design for, human autonomy (rather than just machine autonomy) if it is to genuinely benefit humanity. Yet the effects on human autonomy of digital experiences are (...) neither straightforward nor consistent, and are complicated by commercial interests and tensions around compulsive overuse. This multi-layered reality requires an analysis that is itself multidimensional and that takes into account human experience at various levels of resolution. We borrow from HCI and psychological research to apply a model (“METUX”) that identifies six distinct spheres of technology experience. We demonstrate the value of the model for understanding human autonomy in a technology ethics context at multiple levels by applying it to the real-world case study of an AI-enhanced video recommender system. In the process we argue for the following three claims: 1) There are autonomy-related consequences to algorithms representing the interests of third parties, and they are not impartial and rational extensions of the self, as is often perceived; 2) Designing for autonomy is an ethical imperative critical to the future design of responsible AI; and 3) Autonomy-support must be analysed from at least six spheres of experience in order to approriately capture contradictory and downstream effects.

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three usual (...) operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

[ES] En recientes décadas se ha observado un renovado interés por algunos de los temas clásicos de la ontología, desde áreas de conocimiento externas a la filosofía, sin embargo, este renacimiento ontológico ha «estimulado» una multiplicidad y diversidad de teorías y concepciones «ontológicas» que ha dado como consecuencia una proliferación de «ontologías» y de interminables batallas para determinar qué tipo de «entidades» estudian sus respectivos «dominios», que a su vez se consideran autónomos e independientes entre sí, inclusive de la propia (...) ontología. En este sentido, el propósito de este trabajo es caracterizar y representar de manera adecuada estas «ontologías», dentro del marco general del debate acerca de la naturaleza de la ontología. Es así que, en la primera sección haré un diagnostico de la ontología contemporánea; en la segunda proporcionaré algunas definiciones y caracterizaciones de las principales concepciones, en especial de las denominadas «ontologías aplicadas»; y en la tercera analizaré sí estas concepciones pueden ser consideradas diversos tipos de ontología o simplemente son diversos niveles de ontología. El marco de la discusión no se centrará en confrontar todas estas nociones, sino en describirlas y analizarlas para ofrecer un enfoque sobre el estado actual de la ontología y sus problemas. [EN] In recent decades there has been a renewed interest in some of the classic themes of ontology, from areas of knowledge external to philosophy; however, this ontological revival has «stimulated» a multiplicity and diversity of «ontological» theories and concepts that has resulted in a proliferation of «ontologies» and endless battles to determine what kind of «entities» study their respective «domains», which in turn are considered autonomous and independent, even of ontology itself. In this sense, the purpose of this work is to adequately characterize and represent these «ontologies», within the general framework of the debate about the nature of ontology. Thus, in the first section I will make a diagnosis of contemporary ontology; in the second I will provide some definitions and characterizations of the main concepts, especially the so-called «applied ontologies»; and in the third I will analyze whether these concepts can be considered different types of ontology or simply are different levels of ontology. The framework of the discussion will not center on confronting all these notions, but to describe and analyze them to provide a focus on the current state of ontology and its problems. (shrink)

*Winner of the American Philosophical Association's 2020 Essay Prize in Latin American Thought* This essay offers a novel account of the secularity of Latin American liberation philosophy. It challenges the accepted notion that liberation philosophy applies the methods and approaches of Latin American liberation theology to the philosophical arena, thus putting liberation theology on secular grounds. While this formulation is true insofar as liberation philosophy is not bound by the hermeneutics of any particular religious tradition, this formulation could be misconstrued (...) given that liberation philosophy does not premise such secularization in an undialectical understanding of secularity as secularism that disavows religion. Rather, liberation philosophy’s secularity is dialectical in that it requires constant engagement with re-ligion, not in the hermeneutics of any specific tradition but with “the traditional question of the Absolute.” Due to this often-misunderstood element of liberation philosophy, it has frequently been “ghettoized and relegated to the ‘safe’ area of theological studies,” as Eduardo Mendieta argues. However, I contend that liberation philosophy’s secular grounds offer an original contribution to philosophy as a decolonial and postsecularist liberation philosophy, one that conceives of secularism as an aspect of coloniality to be overcome, an obstacle rather than a benefit for Latin American philosophers seeking to gain a better understanding of our historical conditions.

In this propaedeutic work, through Kant’s own texts, I will try to offer a balanced description and a succinct reconstruction of Kant’s arguments about the possibility and impossibility of Metaphysics. In the first place I will present some criticisms of Metaphysics, then I will visualize the Kantian notion of Metaphysics, as well as its constitutive reasons and moments; and finally, I will analyze what kind of knowledge is Metaphysics and the characteristics and nature of it, so that this «science» is (...) viable. In order to carry out this task, I will assume the hypothesis that Kant’s Metaphysics, in correspondence with the resolution of the third question of knowledge, is a science that integrates practical and theoretical reason into a universal system that seeks transcendence. If Metaphysics has any chance, this would probably be the way. (shrink)

This article asks the question “Why did Plato not write the ‘unwritten doctrine’?” and answers it by citing a combination of two obstacles. The first derives from the limitations of the episteme available to an embodied soul about the essence of the good. Even if the dialectician has access to some kind of knowledge, the mismatch between the unchanging essence of the good and the precarious logoi which aim to identify it (and allow others some measure of access to it) (...) can never fully be overcome. At best, Socrates (or Plato) can lead souls to an incomplete account of it: It is possible that even the most expert dialectician can only have a claim to knowledge, but no absolute certainty. Another obstacle lies in the audience or readership itself: No shortcut to understanding is possible, and yet a mere written presentation, which is all they have, is just such a shortcut, and so represents an empty promise. In memory of Charles H. Kahn (1928–2023), a letter of his from September 5, 1989, concerning the question “Why did Plato not write the ‘unwritten doctrine’?” is published, along with some comments.

Over the past few decades, cognitive science has identified several forms of reasoning that make essential use of conceptual knowledge. Despite significant theoretical and empirical progress, there is still no unified framework for understanding how concepts are used in reasoning. This paper argues that the theory of conceptual spaces is capable of filling this gap. Our strategy is to demonstrate how various inference mechanisms which clearly rely on conceptual information—including similarity, typicality, and diagnosticity-based reasoning—can be modeled using principles derived from (...) conceptual spaces. Our first topic analyzes the role of expectations in inductive reasoning and their relation to the structure of our concepts. We examine the relationship between using generic expressions in natural language and common-sense reasoning as a second topic. We propose that the strength of a generic can be described by distances between properties and prototypes in conceptual spaces. Our third topic is category-based induction. We demonstrate that the theory of conceptual spaces can serve as a comprehensive model for this type of reasoning. The final topic is analogy. We review some proposals in this area, present a taxonomy of analogical relations, and show how to model them in terms of distances in conceptual spaces. We also briefly discuss the implications of the model for reasoning with concepts in artificial systems. (shrink)

[ES] Nicolai Hartmann es uno de los filósofos más significativos en la filosofía contemporánea; empero, en la actualidad es poco conocido por nuestro mundo filosófico, posiblemente debido a que el esplendor de su filosofía coincidió con el naciente giro lingüístico y con el apogeo del existencialismo, los cuales, como se sabe, absorbieron gran parte de la atención y del quehacer filosófico de la época. Lo anterior, de una u otra manera ha dificultado el conocimiento objetivo de su obra. Es por (...) este motivo, que en este breve trabajo, me propongo presentar en forma esquemática una apostilla sobre su vida y su obra —y no una biografía completa—, que nos permita sentar las bases histórico-filosóficas para una primera aproximación a algunas de sus preocupaciones filosóficas. Esta aproximación se completa, en la parte final del trabajo, con una breve relación bibliográfica de algunos estudios introductorios a su vida y obra. [EN] Nicolai Hartmann is one of the most significant philosophers in contemporary philosophy; however, today is little known by our philosophical world, possibly because the splendor of his philosophy coincided with the nascent linguistic turn and the heyday of existentialism, which, as is known, absorbed much of the attention and philosophical work of the time. This, in one way or another has hindered the objective knowledge of his work. It is for this reason that in this short paper, I intend to present in schematic form a commentary on his life and his work —and not a full biography—, that allows us to lay the historical and philosophical foundations for a first approach to some of its philosophical concerns. This approach is completed at the end of the work, with a brief bibliographical note with some introductory studies to his life and work. (shrink)

Generic statements play a crucial role in concept learning, communication and education. Despite many efforts, the semantics of generics remain a controversial issue, as they do not seem to fit our standard theories of meaning. In this article, we attempt to shed light on this problem by focusing on how these sentences function in reasoning. Drawing on a distinction between property and diagnostic generics, we defend three theses: First, property generics are not about facts but express relations between concepts. Second, (...) generics play an important role in everyday reasoning by interacting with our expectations about the world. Third, diagnostic generics emphasise properties that separate the category in the generics from other categories in the same contrast class. We use the theory of conceptual spaces to advance measures of typicality and diagnosticity capable of modelling different aspects of generics and apply them to the modifier effect and the inverse conjunction fallacy. Finally, we discuss the pragmatics of generics. (shrink)

The paper proposes (1.) a non-standard interpretation of the proverbial expression “deuteros plous” by giving a fresh look to Phaedo, 99c9-d1. Then (2.) it proceeds to the philosophical problem raised in this passage according to this interpretation, that is, the problem of the “hypothesis” or the “unproved principle”. It indicates finally (3.) the kernel of truth contained in the standard Interpretation and it concludes with some remarks on the “weakness of the logoi”.

El proceso de aprehensión de lo cognoscible, en la filosofía contemporánea, ha sido tratado desde diversas perspectivas, entre ellas la fenomenológica y la analítica. Cada una de estas perspectivas aportan unos presupuestos filosóficos y procesos metodológicos que nos proporcionan marcos de trabajo para indagar en las vías de aprehensión del conocimiento; sin embargo, empleadas por separado son insuficientes y limitadas. En absoluto se trata de procurar un método universal, sino de integrar e indagar sobre diversos presupuestos, procesos, patrones y estructuras (...) para avanzar en la indagación de la aprehensión del conocimiento. En este sentido, en la primera parte, abordaremos la necesidad de tener reglas (definitorias y estratégicas) para ser parte y avanzar en cualquier «juego», en especial el del conocimiento.

This article presents a reconstruction of the scientific policies established in Ecuador in the years between 1979 and 2007. The purpose is double: on the one hand, it seeks to understand the process of institutionalization of the System of Science and Technology, on the other hand analysing the achievements of three scientific policies established during this period. Hence, the reconstruction is split into three stages: from 1979 to 1994 when the first scientific policy was in place; from 1994 to 2004 (...) the second policy; and between 2005 and 2007 the third policy. To obtain the objective, some of the most relevant normative aspects during each stage are reviewed, as well as institutional statistical records related to Science and Technology. (shrink)

This paper deals with the deuteros plous, literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s Phaedo, the key passage being Phd. 99e4-100a3. I argue that (a) the ‘flight into the logoi’ can have two different interpretations, a standard one and a non-standard one. The issue is whether at 99e-100a Socrates means that both the student of erga and the student of logoi consider images (‘the standard interpretation’), or the student of logoi does not consider images but (...) that “consistency should suffice for truth” (‘the non-standard interpretation’); (b) the non-standard one implies the problem of the hypothesis, a problem analogous to the problem of the elenchus; (c) there is a structural analogy between Descartes’ ontological argument for the existence of God in his 5th Meditation and the final proof for the immortality of the soul in the Phaedo.

La noción de mundos posibles, sostiene que nuestro mundo es un mundo entre otros, un subconjunto de todas las cosas que existen. Esto implica aceptar que existen mundos estructuralmente equivalentes con sus propios lenguajes [formales], que entre sí no tienen ningún estatuto privilegiado, p.e., el mundo y lenguaje del arte o el mundo y lenguaje de la física; no obstante, la idea de aceptar otros mundos equivalentes como mundos posibles epistémica y ontológicamente legítimos para acceder y expresar lo cognoscible del (...) mundo no goza de gran aceptación. En este sentido, de entre las múltiples dimensiones de la noción de mundos posibles anotada, su dimensión lógica, es una de las más extendidas, ésta se entiende como un posible estado de cosas o un posible curso de eventos. Empero, esta concepción es la más restrictiva de la noción de mundos posibles, no sólo porque dicha noción transmuta en una especie de «técnica predictiva» que nos permite analizar y visualizar posibles escenarios de un estado de cosas o un curso de eventos, sino porque fundamentalmente, la noción de mundos posibles pierde gran parte de su potencia conceptual. Hablar de proposiciones como conjuntos de mundos posibles, no es un error, pero es limitar innecesariamente el alcance y campo de acción de la noción de mundos posibles. Si entendemos dicha noción en la versión primaría de Lewis [«Nuestro mundo actual es sólo un mundo entre otros»], sería plausible recuperar, entre otras, las dimensiones ontológica y epistémica de la noción de mundos posibles, y por ende la posibilidad objetiva de indagar en formas alternativas y legitimas de acceder y expresar lo cognoscible del mundo; en este sentido, en este trabajo me propongo: (1) retomar la noción primaria de mundos posibles de Lewis, para analizar y explicitar brevemente sus limitaciones, virtudes y requerimientos; (2) examinar las condiciones de posibilidad de un mundo; y, (3) sugerir los lineamientos epistémicos que deberían considerarse y explicitarse cuando se habla de y desde un mundo posible a la hora de expresar un enunciado.

In his Vermischte Bemerkungen 43, Wittgenstein notices that he was also influenced by Oswald Spengler. The paper deals with the question of in which way Spengler influenced Wittgenstein’s late works and if it really was influence or only a coincidence of ideas. It is put forward that Spengler’s rather unknown philosophy of language influenced Wittgenstein’s philosophy of language, especially the concepts of family resemblance, antiessentialism, and language-game (Sprachspiel). A picture of the famous Neapolitan gesture of “negation” which motivated Wittgenstein to (...) give up the picture theory of language is also shown with an example taken from Andrea de Jorio, La mimica degli antichi investigala nel gestire napoletano, Napoli 1832.

Wittgenstein’s mature philosophy offers a therapeutic way out of some conundrums stemming from taxonomic expectations regarding philosophical description of experience in general. The paper asks if this is also true of the facts of aesthetic experience. This possibility is hinted at by examining an application of the notion of certainty to aesthetic experience. Some traits of possible uses of central concepts of the mature Wittgenstein to a philosophical aesthetics inspired by the “new method” are also canvassed.

"Paraconsistent Belief Revision Based on a Formal Consistency Operator" delves into Belief Revision—a significant area of research in Formal Philosophy that uses logic to model the ways in which human and artificial agents modify their beliefs in response to new information and examines how these changes can be considered rational. -/- Originally authored as a PhD thesis (previously published in Portuguese), this work provides a novel epistemic interpretation of Paraconsistency through Paraconsistent Belief Revision systems. It explores the concept of paraconsistency (...) from the standpoint of epistemic attitudes of acceptance and rejection. -/- This work challenges the traditional notion that accepting a new belief requires retracting its negation from the current epistemic state. The author contends that such reflexive retraction goes against the principle of informational economy, which is a crucial aspect of rationality in the context of belief change. Consequently, the phenomenon of paraconsistency is further examined from this fresh perspective of belief change, shedding light on the complexities of the Logics of Formal Inconsistency (LFIs). These LFIs provide the foundational logic, offering a comprehensive framework for understanding and implementing paraconsistent principles within belief revision systems. -/- This thesis was supervised by Marcelo Esteban Coniglio and co-supervised by Márcio Moretto Ribeiro, as part of Rafael Rodrigues Testa's doctoral studies at the University of Campinas (Unicamp), Brazil.

The anthropologist James Frazer investigates the ritual gesture in search of be- liefs about the physical world by the native. Wittgenstein considers this a case of aspect- blindness, one that is disruptive of the conditions for understanding the native’s most triv- ial gestures. Unable to cast his glance from within the native situation, this methodological view from nowhere has an arresting effect on experience – in particular, the experience of speaking. This interruption is to be examined by means of a (...) thought experiment. Then, through the interplay of the concepts of Spirit and Aspect, a philosophical tool is described to assess the problem that can also serve as practical guide back to ordinary experience. The next step is to examine this way out in a particularly sensitive kind of experience of meaning: the aesthetic experience, also seen as a ritual. We conclude by alluding to a pos- sibly mutual illumination between aesthetic experience, translation studies and a Cavellian take on ordinary language. (shrink)

Aristotle, in his Metaphysics, not only tries to establish a relationship that is direct, coherent, inter-operational and "precise" between this science, its name as a science, and its object of study, but also begins an indignation that tries to set a science — materially adequate and formally correct — to study τὸ ὂν ᾗ ὂν. In order to complete this task, Aristotle does an in-focus strategy that consists on the diffusion of τὸ ὄν in its categories, that allows Aristotle the (...) possibility of formulate a science ἐπιστήμη to study τὸ ὂν ᾗ ὂν at the same time that supports the diffusion of τὸ ὄν in the "different categories or supreme genres" of τὸ ὄν. Due to this argumentation, Aristotle distinguishes the ἐπιστήμη σοφία of any other type of knowledge: the former is fundamentally an enquiry "about the first causes (πρῶτα αἴτια) and the principles (ἀρχὰς)". With this conception in mind, Aristotle was able to characterize several related forms of the ἐπιστήμη σοφία which, as a whole, eventually allow him to establish a science of the principles and causes "maximally universal and referred to…everything real", and in consequence, to "that that is, as long as something is". In this work, I will try to reconstruct such arguments, and offer some observations and conjectures referred to these notions that plausibly incline the scale in favor of an ontological reading of Aristotle’s Metaphysics, in order to contribute to clarify the confusion that exists between the aim of the discipline with the justification to establish the existence of its own object.

A strange dialectical reversal characterizes the oppositions which psychoanalysis posits against philosophy and neuroscience: what psychoanalysis intervenes with as a unique and missing quality of these subjects, reveals itself upon enquiry as already having been a feature of said subjects. This article first discusses the failed intervention of psychoanalysis within the perceived totalities and absolutes of German idealism. Psychoanalysis, founded on an ontological division and internal inconsistency with a retroactive logic, finds this internal contradiction already reflected within the supposed totalities (...) of Schelling and Hegel. Schelling’s “blind act,” a decision with no prior foundation that grounds an abstract identity-in-itself, appears as the counterpart to what Badiou calls the strictly “analytic act.” Hegel’s Science of Logic, in which the inconclusive interpenetration of being and nothing presupposes its own conclusion in the transitions to essence, and in which an internal incompleteness and contradiction are retroactively constitutive of the concept, similarly nullifies the intervention of psychoanalysis. Finally, precisely such a reversal is presented in neuroscience, where the constitutive contradiction of contingently functional neuronal formations in the adaptive “multiple demand” model of executive functioning repeats the contingent and self-contradicting psychoanalytic subject as being its own deference within linguistic, discursive formations.

Conceptual analysis is one of the notions undergoing dramatic changes during Wittgenstein's intermediate period. There's an aspect of such changes which might prove characteristic of the new directions taken by Wittgenstein's thought after 1929: it is the notion of complete analysis. We believe that Wittgenstein's treatment of this notion is also an interesting indication of new concerns generated by the "new method" itself, in terms of its radical openness to dialogism and its anti-dogmatism. Our aim here will be to explore (...) a couple of hints as to why this can be so. (shrink)

The debate over Plato’s “ so called unwritten doctrines”, which he communicated only to a small circle of trusted disciples, has caused a stir among philosophers in recent decades. Rafael Ferber assumes a differentiated position in this controversy. He is convinced that the unwritten doctrines did exist, but that Plato, for reasons inherent in the process of gaining knowledge, was unable to communicate these doctrines even to his closest disciples. In this book, Ferber outlines the discussion and summarizes the (...) standpoints of greatest interest. Ever since Aristotle, we have known that Plato did not put his most important teachings into writing, but instead communicated them only orally to the inner circle of his disciples. While the extant dialogues merely pass down Plato’s “exoteric” doctrines, his most important “esoteric” insights were not meant for the general public. In the meantime, the contents and the significance of Plato’s “unwritten doctrines” have become the subject of debate in philosophical circles. Fifteen years ago, at the height of the controversy over the “unwritten doctrines”, Rafael Ferber entered the fray with a small book. He proposed that Plato was also unable to communicate the “unwritten doctrines” because the highest principles (i.e. the subject of the unwritten doctrines) cannot be known through logical operations due to an epistemological paradox. Ferber’s differentiated position met with great respect and acceptance, although in individual cases it was also rejected. Ferber’s new book again presents the text of 1991, but significantly expands on it through new perspectives and an outline of the discussion it triggered. In this book, the reader learns what is meant by Plato’s unwritten doctrines and what the controversy is all about. (shrink)

La questione sulla verità del cristianesimo è fondamentale e ineludibile. In essa si trova uno dei filoni fondamentali del pensiero di Joseph Ratzinger – Benedetto XVI. In fondo si trovano coinvolti una serie di argomenti che si possono riassumere nel rapporto tra fede e ragione, tra il Dio della fede e il Dio dei filosofi. Nella visione cristiana ambedue non si contrappongono, ma s’incontrano. La “distinzione mosaica” s’incontra con la “distinzione socratica” . La pretesa di verità del cristianesimo conduce a (...) delle conseguenze sia nell’ambito della religione, sia in quello della filosofia e della morale. Per superare la crisi del cristianesimo abbiamo bisogno di recuperare la fiducia nela ragione e tornare alla ricerca della verità. (shrink)

A mudança da concepção do critério geral da significação que tinha Wittgenstein no seu período intermediário para a concepção dos critérios de significação do seu período posterior justifica que se fale numa correlativa mudança na aplicabilidade do conceito de ‘uso’. Acompanhar esta mudança é importante para se caracterizar o âmbito do pragmático tal como Wittgenstein o concebe, e bem assim o tipo de investigação sobre os fundamentos do simbolismo linguístico e sobre a ligação entre linguagem e mundo que esse filósofo (...) advoga como adequada. Este artigo pretende circunscrever algumas das novas questões que, no período intermediário de Wittgenstein , conduziriam a tal mudança conceptual. (shrink)

In this paper two systems of AGM-like Paraconsistent Belief Revision are overviewed, both defined over Logics of Formal Inconsistency (LFIs) due to the possibility of defining a formal consistency operator within these logics. The AGM° system is strongly based on this operator and internalize the notion of formal consistency in the explicit constructions and postulates. Alternatively, the AGMp system uses the AGM-compliance of LFIs and thus assumes a wider notion of paraconsistency - not necessarily related to the notion of formal (...) consistency. (shrink)

In the whole Corpus Platonicum, we find in principle only one "direct argument" (Charles Kahn) for the existence of the ideas (Tim.51d3-51e6). The purpose of the article is to analyse this argument and to answer the question of why Plato in the Timaeus again defended the existence of the ideas despite the objections in the Parmenides. He defended it again because the latent presupposition of the apories in the Parmenides, the substantial view of sensibles, is removed through the introduction of (...) space as "substantialized extension". First (I) it is shown that Plato remained in dialogues, like the Sophist and Politicus, faithful to the "theory of ideas" despite his criticism in the Parmenides. The common theme in the trilogy of the Theaetetus, Sophist and Politicus is to refute relativism by showing that any relativism presupposes something absolute that is something like the "theory of ideas". The second part of the paper (II) examines closely the logical structure of the argument for the existence of ideas in the Timaeus (51d3-52a7). The third part (III) shows how this argument can avoid the criticism of ideas in the Parmenides. In the Parmenides, sensibles are treated as substantial entities. But, as the Timaeus shows, sensibles are not substantial entities but merely qualities, namely qualities of space, which is the only substance in the sensible world. A shortened English version of the paper appeared in Proceedings of the Fourth Symposium Platonicum, Granada, Selected papers, ed. by T. Calvo/L. Brisson, Academia Verlag, St. Augustin, 1997, 179-186. -/- But the only "direct argument" (Tim.51d3-51e6) seems to be interestingly flawed. Cf. Ferber, Rafael; Hiltbrunner, Thomas, (2005). (shrink)

The article tries to prove that the famous formula "epekeina tês ousias" has to be understood in the sense of being beyond being and not only in the sense of being beyond essence. We make hereby three points: first, since pure textual exegesis of 509b8–10 seems to lead to endless controversy, a formal proof for the metaontological interpretation could be helpful to settle the issue; we try to give such a proof. Second, we offer a corollary of the formal proof, (...) showing that not only self-predication of the form of the Good, but of any form is not possible, that is: no form of F has the form of F. Third, we apply Spinoza’s distinction between an ens imaginarium and a chimaera to Plato’s Idea of the Good. (shrink)

Since 1976, when Thomas A. Szlezák held his inaugural lecture as a private lecturer at the University of Zurich entitled "The Dialogue Form and Esotericism: On the Interpretation of the Platonic Dialogue the Phaedrus", the now-emeritus professor at Tübingen has advocated a particular interpretation of the Platonic dialogues and especially of the Phaedrus: namely, that what is referred to in the latter dialogue—without further explanation—as "more valuable" than what is set down in writing corresponds to Plato's "so called unwritten doctrines", (...) or for Szlezák, "unwritten...

Despite the fact that Aristotle and Frege/Russell differ in how to understand the ambiguity in the meaning of the word “is”, their theories share a common feature: “is” does not have a normative meaning. This paper, however, (I) shows (a) that there is a normative meaning of “is” (and correspondingly a constative meaning of the word “ought”) and (b) that the ambiguity of “is” is itself ambiguous. Furthermore, it proposes (c) a performative criterion for making a distinction between constative and (...) normative “is”. Thereby, (II) a new interpretation of Kant’s critique of the ontological argument (CPR A 598/B626) makes sense: The difference between being as a real predicate and being as a position depends on the difference between “is” as a descriptive and “is” as a normative predicate. (III) The criterion also makes possible a new answer to Leibniz’s and Schelling’s question, “Why is there something rather than nothing?”: The “is” in “there is something” is normative and the question means “Why shall there be something rather than nothing?”. As “there shall be nothing” is self-refuting, the question evokes an ultimate foundation in a practical sense. (shrink)

Reasons for action is a widely employed methodology in practical philosophy, and especially in moral philosophy. Reasons are facts that explain and justify actions. But, conceptually, if reasons were causes, incontinent actions would be impossible. When an agent ranks an evaluation about what to do as his best judgement, it entails that he has a reason for acting as that judgement prescribes. But when an agent acts incontinently, he acts in accordance to an intention that is not aligned with his (...) best evaluative judgement. Yet, if the agent’s best evaluative judgement provides him a reason for action, this reason should also be his strongest reason, and therefore, the strongest cause. How then can it be possible that an agent incontinently acts according to a reason of inferior causal strength? In this paper, I analyze how Davidson’s argument for the possibility of incontinent actions interacts with his causal theory of actions. I argue that Davidson’s proposal does not fully respect the two principles of intentional rationality, that he himself claims to be compelling. Lastly, I sketch some initial steps that might be helpful to drawing more precise conceptual distinctions in terms of the rationality of incontinent actions. (shrink)

Paraconsistency is the study of logical systems with a non-explosive negation such that a pair of contradictory formulas (with respect to such negation) does not necessarily imply triviality, discordant to what would be expected by contemporary logical orthodoxy. From a purely logical point of view, the significance of paraconsistency relies on the meticulous distinction between the general notions of contradictoriness and triviality of a theory—respectively, the fact that a given theory proves a proposition and its negation, and the fact that (...) a given theory proves any proposition (in the language of its underlying logic). Aside from this simple rationale, the formal techniques and approaches that meet the latter definitional requirement are manifold. Furthermore, it is not solely the logical-mathematical properties of such systems that are open to debate. Rather, there are several foundational and philosophical questions worth studying, including the very question about the nature of the contradictions allowed by paraconsistentists. This entry aims to advance a brief account of some distinct approaches to paraconsistency, providing a panorama on the development of paraconsistent logic. (shrink)
