The question asked in this article is: what is a parasite?. Defining a parasite requires defining its host at the same time. A difficult question therefore arises about host-parasite relationships. The object of general parasitology is in fact to study the relationship between a host and its parasite. The initial question what is a parasite? has to be reformulated within a conceptual framework, that of relationship. This article is an attempt to transpose into parasitology some concepts which have been profitable (...) in the fields of physics and chemistry. The studies of R. Thom about the individual are also used. Concepts like that of field and principles like that of minimization are probably operational on a high level of organization. The description of host-parasite relationships could benefit from these concepts. (shrink)

EI tratamiento que hace Descartes deI ‘yo pienso-existo’, lejos de todo proceder inferencial, nos muestra la condición propia de un pensamiento que es “res cogitans”: mi ‘asistir a’ como condición originaria de la fuerza de realidad que soy. Así, el conocimiento que tengo de mí como pensamiento es prejudicativo: no necesita afirmación alguna, sino que expresa prevolitivamente el ser-siendo, o acto, que soy como pensamiento, y que no se extiende a mi cuerpo. The treatment Deseartes does of ‘I think - (...) I exist’ far from any inference, shows the conditioning which is proper of a “res cogitans” thought: my ‘attendance to’ as the originary conditioning of the strength of reality which I am. Thus, the Knowledge I have of myself as thought is prejudicative: it needs no affirmation but it expresses prevolitionally the ‘to be-being’, or act, that I am as thought and which does not extend to my body.

Quanto às aproxima- ções, analisar-se-á, de um lado, a concepção do sujeito em ambos os filósofos e, de outro, suas respectivas defesas do realismo. Quanto (...) aos distanciamentos, abordar-se-á, de uma parte, as críticas dos referidos filósofos ao idealismo e, de outra, suas devidas concepções do espaço e do tempo. (shrink)

In this paper we discuss the extent to which the very existence of substructural logics puts the Tarskian conception of logical systems in jeopardy. In order to do this, we highlight the importance of the presence of different levels of entailment in a given logic, looking not only at inferences between collections of formulae but also at inferences between collections of inferences—and more. We discuss appropriate refinements or modifications of the usual Tarskian identity criterion for logical systems, and propose an (...) alternative of our own. After that, we consider a number of objections to our account and evaluate a substantially different approach to the same problem. (shrink)

When discussing Logical Pluralism several critics argue that such an open-minded position is untenable. The key to this conclusion is that, given a number of widely accepted assumptions, the pluralist view collapses into Logical Monism. In this paper we show that the arguments usually employed to arrive at this conclusion do not work. The main reason for this is the existence of certain substructural logics which have the same set of valid inferences as Classical Logic—although they are, in a clear (...) sense, non-identical to it. We argue that this phenomenon can be generalized, given the existence of logics which coincide with Classical Logic regarding a number of metainferential levels—although they are, again, clearly different systems. We claim this highlights the need to arrive at a more refined version of the Collapse Argument, which we discuss at the end of the paper. (shrink)

Many authors have considered that the notions of paraconsistency and dialetheism are intrinsically connected, in many cases, to the extent of confusing both phenomena. However, paraconsistency is a formal feature of some logics that consists in invalidating the rule of explosion, whereas dialetheism is a semantical/ontological position consisting in accepting true contradictions. In this paper, we argue against this connection and show that it is perfectly possible to adopt a paraconsistent logic and reject dialetheism, and, moreover, that there are examples (...) of non-paraconsistent logics that can be interpreted in a dialetheic way.

Anti-exceptionalism about logic states that logical theories have no special epistemological status. Such theories are continuous with scientific theories. Contemporary anti-exceptionalists include the semantic paradoxes as a part of the elements to accept a logical theory.

In this article, we will present a number of technical results concerning Classical Logic, ST and related systems. Our main contribution consists in offering a novel identity criterion for logics in general and, therefore, for Classical Logic. In particular, we will firstly generalize the ST phenomenon, thereby obtaining a recursively defined hierarchy of strict-tolerant systems. Secondly, we will prove that the logics in this hierarchy are progressively more classical, although not entirely classical. We will claim that a logic is to (...) be identified with an infinite sequence of consequence relations holding between increasingly complex relata: formulae, inferences, metainferences, and so on. As a result, the present proposal allows not only to differentiate Classical Logic from ST, but also from other systems sharing with it their valid metainferences. Finally, we show how these results have interesting consequences for some topics in the philosophical logic literature, among them for the debate around Logical Pluralism. The reason being that the discussion concerning this topic is usually carried out employing a rivalry criterion for logics that will need to be modified in light of the present investigation, according to which two logics can be non-identical even if they share the same valid inferences.

Transhumanism proposes human enhancement while regarding the human body as unfit for the future. This fulfills age-old aspirations for a perfect and durable body. We use “alienation” as a concept to analyze this mismatch between human aspirations and our current condition. For Hannah Arendt alienation may be accounted for in terms of earth- and world-alienation, as well as alienation from human nature, and especially from the given (“resentment of the given”). In transhumanism, the biological body is an impediment to human (...) accomplishment. At most, this movement accepts “clean” bodies, not bodies with excretions. We argue that real human bodies are valued in the event of giving birth, so a modified concept that Arendt proposed, natality, seems a suitable way to explore the dialectic alienation-reconciliation involving the body (Arendt’s “A child has been born unto us”), when re-read by some feminist scholars.

Adding a transparent truth predicate to a language completely governed by classical logic is not possible. The trouble, as is well-known, comes from paradoxes such as the Liar and Curry. Recently, Cobreros, Egré, Ripley and van Rooij have put forward an approach based on a non-transitive notion of consequence which is suitable to deal with semantic paradoxes while having a transparent truth predicate together with classical logic. Nevertheless, there are some interesting issues concerning the set of metainferences validated by this (...) logic. In this paper, we show that this logic, once it is adequately understood, is weaker than classical logic. Moreover, the logic is in a way similar to the paraconsistent logic LP. (shrink)

In some recent articles, Cobreros, Egré, Ripley, & van Rooij have defended the idea that abandoning transitivity may lead to a solution to the trouble caused by semantic paradoxes. For that purpose, they develop the Strict-Tolerant approach, which leads them to entertain a nontransitive theory of truth, where the structural rule of Cut is not generally valid. However, that Cut fails in general in the target theory of truth does not mean that there are not certain safe instances of Cut (...) involving semantic notions. In this article we intend to meet the challenge of answering how to regain all the safe instances of Cut, in the language of the theory, making essential use of a unary recovery operator. To fulfill this goal, we will work within the so-called Goodship Project, which suggests that in order to have nontrivial naïve theories it is sufficient to formulate the corresponding self-referential sentences with suitable biconditionals. Nevertheless, a secondary aim of this article is to propose a novel way to carry this project out, showing that the biconditionals in question can be totally classical. In the context of this article, these biconditionals will be essentially used in expressing the self-referential sentences and, thus, as a collateral result of our work we will prove that none of the recoveries expected of the target theory can be nontrivially achieved if self-reference is expressed through identities.

It is widely accepted that a theory of truth for arithmetic should be consistent, but -consistency is a highly desirable feature for such theories. The point has already been made for first-order languages, though the evidence is not entirely conclusive. We show that in the second-order case the consequence of adopting -inconsistent theories of truth are considered: the revision theory of nearly stable truth T # and the classical theory of symmetric truth FS. Briefly, we present some conceptual problems with (...) ω-inconsistent theories, and demonstrate some technical results that support our criticisms of such theories. (shrink)

Transhumanist thought on overpopulation usually invokes the welfare of present human beings and the control over future generation, thus minimizing the need and meaning of new births. Here we devise a framework for a more thorough screening of the relevant literature, to have a better appreciation of the issue of natality. We follow the lead of Hannah Arendt and Brent Waters in this respect. With three overlapping categories of words, headed by “natality,” “birth,” and “intergenerations,” a large sample of books (...) on transhumanism is scrutinized, showing the lack of sustained reflection on the issue. After this preliminary scrutiny, a possible defense of natality in face of modern and transhumanist thought is marshaled, evoking a number of desirable human traits. One specific issue, the impact of modern values on natality, is further explored, reiterating that concerns about overpopulation and enhanced humans should keep in sight the natural cycle of birth and death.

Negli anni di passaggio dal XII al XIII secolo, il cisterciense Garnerio di Rochefort si dedica alla composizione di un breve trattato, il _De contrarietatibus in Sacra Scriptura_. L’opera, tuttora inedita, fa ricorso all’uso delle arti sermocinali per risolvere le ambiguità scritturali. Nel prologo del _De contrarietatibus_ emerge un peculiare interesse del cisterciense verso la disciplina della retorica e, in particolare, verso l’impiego delle figure tropiche nella comprensione dei contenuti della Rivelazione. A ben vedere, tuttavia, la scelta garneriana di ricorrere (...) all’affinamento degli strumenti della retorica per illuminare il significato della Scrittura trova una piena giustificazione solo alla luce della sua concezione della _natura_ e della _Scriptura_ come teofanie e/o simboli. Ora in quest’orizzonte simbolico, di impianto neoplatonico-dionisiano, è sempre all’opera nelle _res_, così come nel linguaggio, un meccanismo di traslazione, un’estensione della parola, oltre il suo contenuto ordinario, a un significato altro, di natura spirituale. Dunque la fattura retorica delle espressioni bibliche assume un valore conoscitivo, e non semplicemente ornamentale, perché capace di palesare, attraverso un dialettico gioco di corrispondenze e/o di rotture, una proporzionalità analogica tra il visibile e l’invisibile. _In the intervening years between the XII and XIII centuries, Cistercian Garnerius of Rochefort devoted himself to the composition of a short treatise,_ De contrarietatibus in Sacra Scriptura._ The work, still unpublished, makes use of the sermocinal arts to resolve scriptural ambiguities. The prologue to _De contrarietatibus _reveals a peculiar interest of the Cistercian in the discipline of rhetoric and, in particular, in the use of tropes in understanding the contents of Revelation. On closer inspection, however, garnerian’s choice to resort to the refinement of the tools of rhetoric to illuminate the meaning of Scripture finds full justification only in light of his conception of_ natura _and_ Scriptura_ as theophanies and/or symbols. Now in this symbolic horizon, of Neo-Platonic-Dionysian framework, there is always at work in _res_, as well as in language, a mechanism of translation, an extension of the word, beyond its ordinary content, to another meaning of a spiritual nature. So the rhetorical workmanship of biblical expressions assumes a cognitive, and not merely ornamental, value because it is capable of manifesting, through a dialectical interplay of correspondences and/or ruptures, an analogical proportionality between the visible and the invisible. _.

In this paper, we present a non-trivial and expressively complete paraconsistent naïve theory of truth, as a step in the route towards semantic closure. We achieve this goal by expressing self-reference with a weak procedure, that uses equivalences between expressions of the language, as opposed to a strong procedure, that uses identities. Finally, we make some remarks regarding the sense in which the theory of truth discussed has a property closely related to functional completeness, and we present a sound and (...) complete three-sided sequent calculus for this expressively rich theory.

Rejecting the Cut rule has been proposed as a strategy to avoid both the usual semantic paradoxes and the so-called v-Curry paradox. In this paper we consider if a Cut-free theory is capable of accurately representing its own notion of validity. We claim that the standard rules governing the validity predicate are too weak for this purpose and we show that although it is possible to strengthen these rules, the most obvious way of doing so brings with it a serious (...) problem: an internalized version of Cut can be proved for a Curry-like sentence. We also evaluate a number of possible ways of escaping this difficulty. (shrink)

The logics of formal inconsistency are logics tolerant to some amount of contradiction, but in which some versions of explosion still hold. The main result of this paper is a reconstruction of two such logics in the dialogical framework. By doing so, we achieve two things. On the one hand, we provide a formal approach to argumentative situations where some contradictions may occur while keeping the idea that there may still be situations in which some propositions are ‘safe’ in the (...) sense of immunity to the contradictions. On the other hand, we open a new line of study on these logics, in the context of the game-theoretical approach to semantics born in the 1960s, with various interesting perspectives, some of which are discussed at the end of this article.

Transhumanists, like other elites in modernity, place great value on human creativity, and advances in human enhancement and AI form the basis of their propos- als for boosting it. However, there are problems with this perspective, due to the unique ways in which humans have evolved, procreated and socialized. I first describe how creativity is related to past evolution and developmental aspects in children, stressing pretend play and the ambivalent character of creativity. Then, I outline proposals for enhancing creativity, be (...) it in embodied humans on the way to a superior species, in AI- related beings (virtual reality, robotics), or even in any degree of mixture in human- machine interaction. In the final section, I describe intrinsic limits to these proposals, such as the absence of a good understanding of human psychology by the proponents of enhancement; the lack of interest in the subjective side of creativity (for one’s own sake); delayed maturation and the ambivalence of pretend play in childhood; and the contrariness typical of new human generations. As for the enhancement of creativity, it is argued that creativity in its social context may be the victim of its own past success. On the other hand, an asymmetry between virtual beings and children is described— the latter can behave in a nasty way, it is part of their growth and creativity, whereas the former are not supposed to cause any harm to human beings. In sum, despite impressive progress in several scientific and technological interventions in creativity, philosophical questions emerge that place many constraints on transhumanist dreams of endless creativity.

Me propongo aquí una reflexión sobre la crisis del humanismo que afecta profundamente a la sociedad y la cultura contemporáneas en todas sus dimensiones. De un modo falsamente optimista, se ha opuesto a esta crisis la figura de un post humanismo triunfante, resultado de los desarrollos de la tecnología contemporánea y sus posibilidades de intervención en el cuerpo y el alma del hombre. Haré aquí una evaluación crítica de ese optimismo, sin por ello reivindicar el viejo humanismo y su razón (...) colonizadora. Trataré de plantear a través de Heidegger y Agamben la condición post humanista y post histórica –en el sentido moderno– en la que nos encontramos. Pero luego intentaré pensar junto a Nietzsche y Bataille una figura del hombre que no es nueva, sino una figura más antigua y creo más profunda, que quedó sepultada bajo la irrupción tectónica del humanismo y su empresa civilizatoria.

Who Comes After the Subject offers the most comprehensive overview to date of contemporary French thinking on the question of the "subject." Nineteen philosophers and critics offer diverse perspectives on the subject as it has manifested itself in our modern discourses: the subject of philosophy, of the State, of history, of psychoanalysis.

My aim in this paper is to examine some of the distinctive facets of human action in Spinoza’s philosophy and show their intrinsic connection with each other. By analyzing in detail how Spinoza addresses different aspects of human action in his main work, the Ethics, it is possible to notice that for him free human agency implies two interrelated features: on the one hand, the adequate knowledge of the causes that determine it, and, on the other hand, a growing capacity (...) to impact with greater power the scenarios in which it takes place. Thus, in contrast with quietist and passive readings, I show in the following that the two aforementioned characteristics are part of the Spinozian philosophical conception of agency as such. By pursuing this line of thought, it is also possible to establish a link—not always noticed in the secondary literature—with some of the central lines of thought contained in the Theological-Political Treatise. In discussing these theses, I advance the idea that the Spinozian conception of human agency involves a serious readjustment of the metaphysical vision of the agent, a change in her conduct and ethical practices, and an altogether different conception of politics and religion.

It is widely accepted that classical logic is trivialized in the presence of a transparent truth-predicate. In this paper, we will explain why this point of view must be given up. The hierarchy of metainferential logics defined in Barrio et al. and Pailos recovers classical logic, either in the sense that every classical inferential validity is valid at some point in the hierarchy ), or because a logic of a transfinite level defined in terms of the hierarchy shares its validities (...) with classical logic. Each of these logics is consistent with transparent truth—as is shown in Pailos —, and this suggests that, contrary to standard opinions, transparent truth is after all consistent with classical logic. However, Scambler presents a major challenge to this approach. He argues that this hierarchy cannot be identified with classical logic in any way, because it recovers no classical antivalidities. We embrace Scambler’s challenge and develop a new logic based on these hierarchies. This logic recovers both every classical validity and every classical antivalidity. Moreover, we will follow the same strategy and show that contingencies need also be taken into account, and that none of the logics so far presented is enough to capture classical contingencies. Then, we will develop a multi-standard approach to elaborate a new logic that captures not only every classical validity, but also every classical antivalidity and contingency. As a€truth-predicate can be added to this logic, this result can be interpreted as showing that, despite the claims that are extremely widely accepted, classical logic does not trivialize in the context of transparent truth.

The purpose of this article is to examine Salvian of Marseilles’ (ca. 400–490 CE) invective in De gubernatione Dei against his Christian audience pertaining to their sexual roles and behaviour as slaveholders. It is argued that rather than considering the oppressive practice of slavery in itself as a reason for moral rebuke and divine punishment, Salvian highlights the social shame that arose from the sexual vices Christian slaveholders committed with their slaves. Salvian forwards three accusations against his opponents that concern (...) slavery and sexual vice. Firstly, he asserts that Christian slaveholders have no self-control. Secondly, the polyamorous relationships slaveholders have with numerous slaves resemble shameful and adulterous unions, namely concubinage and even polygamy. Thirdly, Roman-Christian slaveholders behave in a worse manner than barbarians (i.e. the argument of ethnicity). Each of these accusations is examined in detail in the study. (shrink)

The article analyses innovative ethno-geographical systems of the first century BC. During Hellenistic times, the science of geography made use of increasingly advanced mathematical and astronomical skills to ensure a scientific basis for the cartographical project; however, this geographical research apparently disregarded the natural and human environments. There is a paradigm change in the referred century. The Stoic Posidonius focuses on the concept of zones found in the early philosophers and finds a compromise between the ‘scientific’ and the ‘descriptive’ geographies. (...) Likewise, Vitruvius conveys a geographical system which associates climatic, somatic, and psychic features. (shrink)

In different papers, Carnielli, W. & Rodrigues, A., Carnielli, W. Coniglio, M. & Rodrigues, A. and Rodrigues & Carnielli, present two logics motivated by the idea of capturing contradictions as conflicting evidence. The first logic is called BLE and the second—that is a conservative extension of BLE—is named LETJ. Roughly, BLE and LETJ are two non-classical logics in which the Laws of Explosion and Excluded Middle are not admissible. LETJ is built on top of BLE. Moreover, LETJ is a Logic (...) of Formal Inconsistency. This means that there is an operator that, roughly speaking, identifies a formula as having classical behavior. Both systems are motivated by the idea that there are different conditions for accepting or rejecting a sentence of our natural language. So, there are some special introduction and elimination rules in the theory that are capturing different conditions of use. Rodrigues & Carnielli’s paper has an interesting and challenging idea. According to them, BLE and LETJ are incompatible with dialetheia. It seems to show that these paraconsistent logics cannot be interpreted using truth-conditions that allow true contradictions. In short, BLE and LETJ talk about conflicting evidence avoiding to talk about gluts. I am going to argue against this point of view. Basically, I will firstly offer a new interpretation of BLE and LETJ that is compatible with dialetheia. The background of my position is to reject the one canonical interpretation thesis: the idea according to which a logical system has one standard interpretation. Then, I will secondly show that there is no logical basis to fix that Rodrigues & Carnielli’s interpretation is the canonical way to establish the content of logical notions of BLE and LETJ. Furthermore, the system LETJ captures inside classical logic. Then, I am also going to use this technical result to offer some further doubts about the one canonical interpretation thesis. (shrink)

This paper is a reply to Benjamin Smart’s : 319–332, 2013) recent objections to David Armstrong’s solution to the problem of induction : 503–511, 1991). To solve the problem of induction, Armstrong contends that laws of nature are the best explanation of our observed regularities, where laws of nature are dyadic relations of necessitation holding between first-order universals. Smart raises three objections against Armstrong’s pattern of inference. First, regularities can explain our observed regularities; that is, universally quantified conditionals are required (...) for explanations. Second, if Humean’s pattern of inference is irrational, then Armstrong’s pattern of inference is also irrational. Third, universal regularities are the best explanation of our observed regularities. I defend Armstrong’s solution of induction, arguing against these three claims. (shrink)

Para explorar las diferencias significativas entre estos dos pensadores, la primera parte de este articulo considerará sus ideas ontológicas. Comenzando con su preocupación común por la multiplicidad, exploraremos el movimiento fundacional de Deleuze hacia diferentes tipos de multiplicidad. La crítica de Badiou a este enfoque estará relacionada con su defensa de los recursos abstractos de la teoría de conjuntos en oposición a las síntesis concretas con las que Deleuze busca comenzar. La segunda parte de este documento explorará las consecuencias de (...) los compromisos ontológicos de Deleuze cuando se trata de la ética del acontecimiento exigido por Badiou. El compromiso de Deleuze con el estoicismo proporcionará el escenario para su explicación de cómo ocurren los acontecimientos y representa una fuente de pensamiento y actividad. En la tercera y última parte se buscará evaluar la explicación de Deleuze sobre el papel de los acontecimientos en situaciones particulares y en las actividades de los sujetos que responden a estos. Esto nos permitirá sacar conclusiones sobre la crítica de Badiou a Deleuze y la capacidad de Deleuze para resistir estas críticas. Argumentaré que Deleuze comparte con Badiou la preocupación de mantener una visión clara del tema como una figura comprometida en la búsqueda de proyectos nuevos e inauditos que responden al llamado de los acontecimientos.

The aim of this paper is to show that it’s not a good idea to have a theory of truth that is consistent but ω-inconsistent. In order to bring out this point, it is useful to consider a particular case: Yablo’s Paradox. In theories of truth without standard models, the introduction of the truth-predicate to a first order theory does not maintain the standard ontology. Firstly, I exhibit some conceptual problems that follow from so introducing it. Secondly, I show that (...) in second order theories with standard semantics the same procedure yields a theory that doesn’t have models. So, while having an ω- inconsistent theory is a bad thing, having an unsatisfiable theory of truth is actually worse. This casts doubts on whether the predicate in question is, after all, a truthpredicate for that language. Finally, I present some alternatives to prove an inconsistency adding plausible principles to certain theories of truth. (shrink)
