This article is a preliminary presentation of conjunctive paraconsistency, the claim that there might be non-explosive true contradictions, but contradictory propositions cannot be considered separately true. In case of true ‘p and not p’, the conjuncts must be held untrue, Simplification fails. The conjunctive approach is dual to non-adjunctive conceptions of inconsistency, informed by the idea that there might be cases in which a proposition is true and its negation is true too, but the conjunction is untrue, Adjunction fails. While (...) non-adjunctivism is a well-known option, the other view is not so much studied nowadays, but it was not unknown in the tradition, and there are some positive suggestions, in recent literature, that the position is plausible and deserves to be developed. The article compares conjunctivism, non-adjunctivism and dialetheism, then focuses on some possible justifications, costs and benefits of the conjunctive view. (shrink)

In his Lectures on the History of Philosophy, Hegel develops a subtle analysis of Megarian paradoxes: the Liar, the Veiled Man and the Sorites. In this paper, we focus on Hegel's interpretation of...

Legends and stories about fabulous races that dwelt in India or in Africa circulated in Iran probably since the Achaemenid times. Unfortunately, scholarship on this topic has neglected some late Iranian and, especially, Zoroastrian sources, such as Draxt ī āsūrīg, the Bundahišn, the Ayādgār ī Jāmāspīg, and the New Persian epic Šāhnāme. This article examines the aforementioned sources and discusses their accounts of five fabulous races from an Iranian, and especially Zoroastrian, perspective and through a comparative approach to some similar (...) neighboring traditions.

Stratified properties such as ‘happy unhappiness’, ‘ungrounded ground’, ‘fortunate misfortune’, and evidently ‘true falsity’ may generate dialetheias (true contradictions). The aim of the article is to show that if this is the case, then we will have a special, conjunctive, kind of dialetheia: a true state description of the form ‘Fa and not Fa’ (for some property F and object a), wherein the two conjuncts, separately taken, are to be held untrue. The particular focus of the article is on happy (...) unhappiness: people suffering from (or enjoying) happy unhappiness (if there is some situation or state of mind of this kind) cannot be truly said ‘happy’ or ‘unhappy’, but we can say they are both. In the first section three cases of conjunctive stratification are presented; in the second section the logic of stratified contradictions is explored. The last section focuses on eudemonistic ascriptions: stated that a is happy to be unhappy (or unhappy to be happy), should we say a is happy? unhappy? both? neither? (shrink)

Résumé — Cet article se propose de fournir une contribution au débat interprétatif sur le principe de la limitation de l’acte par la puissance dans la démonstration de l’infinité de Dieu de la Summa theologiae de Thomas d’Aquin à travers une enquête à caractère historique qui expose quelques-unes des étapes capitales de l’histoire de cette preuve. Le désaccord qui divise les interprètes contemporains à propos du rôle joué par le principe susdit hérite, en réalité, d’une opposition séculaire parmi les commentateurs (...) de Thomas qui remonte à la discussion qui suivit l’intervention de Tommaso de Vio et de Francesco Silvestri. D’autre part, l’incontestable présence chez certains commentateurs classiques de Thomas, Jean de Saint-Thomas in primis, d’une position qui sépare la preuve de la Summa du principe de la limitation de l’acte par la puissance réceptive, loin d’exprimer une orthodoxie par rapport à la tradition la plus ancienne, constitue un renversement par rapport à la lecture de Cajetan et de Silvestre de Ferrare, qui s’était affirmée comme l’interprétation canonique du texte de Thomas.— Questo articolo si propone di fornire un contributo al dibattito interpretativo sul principio della limitazione dell’atto attraverso la potenza nella dimostrazione dell’infinità di Dio nella Summa theologiae di Tommaso d’Aquino attraverso un’indagine di carattere storico che espone alcune delle tappe capitali della storia di questa prova. Il disaccordo che divide gli interpreti contemporanei sul ruolo giocato dal principio suddetto eredita, in realtà, un’opposizione secolare fra i commentatori di Tommaso che risale alla discussione che seguî gli interventi di Tommaso de Vio e di Francescio Silvestri. D’altra parte, la presenza, incontestabile, in alcuni commentatori classici di Tommaso, primo fra tutti Giovanni di san Tommaso, di una posizione che separa la prova della Summa dal principio della limitazione dell’atto attraverso la potenza recettiva, lungi dal configurarsi nei termini di una posizione ortodossa rispetto alla tradizione più antica, costituisce un ribaltamento della lettura di Cajetano e di Silvestro da Ferrare, che si era affermata come l’interpretazione canonica del testo di Tommaso.

According to Descartes, vegetative and sensitive activities, which in the Aristotelian tradition were considered dependent on the soul, are pure effects of corporeal dispositions. What is, however, the relationship between this doctrine and Descartes’s metaphysical claim in the Meditations, namely, that the mind is the only cause of thought? In the Meditations, Descartes does not provide a doctrine of vegetative and sensitive functions, and he does not even establish the canonic Cartesian thesis that they are not dependent on the soul. (...) In claiming that the lowest functions cannot be attributed to the soul, the Second Meditation is not making an ontological point. Nevertheless, in spite of this, the Meditations teach us something very important about the lowest functions: that both vegetative and sensitive functions depend on the soul is not, and never will be, a necessarily true proposition.

Is it possible truthfully to assert the non-existence of truth? It is a classical problem whose solution is still controversial. I present here an analysis of the sentence “there is no truth” (and its translations and paraphrases, such as “no proposition is true”, “every proposition is false”), with some remarks about its epistemological and ontological implications, and its consequences tor a general theory of reason.

The focus of this article is the notion of alethic rights, the rights related to truth. The concept of truth grounds many norms and customary and official rules, but there is no clear and shared idea about its power to generate specific rights. The juridical and political archetype called ‘the right to truth’ is still subject of controversies, and there are doubts about its being a real ‘right,’ to be protected by positive (new) norms. In the article the problem is (...) explored in truth-theoretical perspective: can philosophy support the idea of truth as a source of rights? Can an updated and well-developed theory of truth be proposed, to help activists and theorists concerned with the need for truth of individuals and communities? I present six alethic rights, corresponding to six different aspects of the human need for truth, then I specifically focus on the truth theory that can justify the hypothesis. (shrink)

The central thesis of JC Beall’s paraconsistent Christology is that Christ, being human and divine, is a contradictory being, and a rational Christology can accept it, since logic nowadays does not exclude the possibility of true contradictions. In this paper, I move from Beall’s theory and I present an alternative view. I quote seven statements of the so-called ‘Athanasian Creed’ which synthesizes the results of conciliar Christology. The aim of the Creed is to combat monophysitism by stressing the duplicity and (...) unity of Christ: two (incompatible) natures inseparably joined in only one person. I note that the two-in-one principle, so intended, may be seen as an ancestor of what has been called ‘conjunctive paraconsistency’, whereby there could be true contradictions but contradictories cannot be separately true. I specifically oppose this view to Beall’s idea of Christ’s human divinity (or divine humanity) as a glut, showing that in the conjunctive account, true contradictions do not require any overlapping or joint ascription of truth and falsity.

Suppose a person blushes iff what she says is false and she says: ‘I am blushing’. If she blushes, she doesn’t, and if she doesn’t, she does. This Blushing Liar is a new paradox, similar in some respects to the Pinocchio Paradox : Pinocchio’s nose grows iff he says some falsity, and he says: ‘my nose is growing’. Both paradoxes involve physical properties, and both, supposedly, confirm the existence of metaphysical dialetheias. In the paper, we note first that while PP (...) relies on the rather implausible scenario of a wooden puppet whose nose grows iff he is lying, so it is debunked by the objection of fictionality, BL is more plausible. Many people in our world blush, and it is not difficult to imagine someone whose saying is causally related to blushing in a similar way. A second question is whether blushing can be directly connected to falsity, without deliberate conscience, on the part of the speaker, of saying a false statement. So we explore the consequences of intending ‘I am blushing’ as a ‘lie’, in the strict meaning of the term, and we claim there is no substantial difference, but for the fact that the paradoxical effect is even more plausible. Third, we check whether BL and PP do really release metaphysical dialetheias, and we argue they do not: they lack the fundamental requisite of Liar-like contradictions, i.e. the stratification of properties.

In a recent paper by Casasanto and Pitt (2019), the authors addressed a debate regarding the role of order and magnitude in SNARC and SNARC‐like effects. Their position is that all these effects can be explained by order, while magnitude could only account for a subset of evidence. Although we agree that order can probably explain the majority of these effects, in this commentary we argue that magnitude is still relevant, since there is evidence that cannot be explained based on (...) ordinality alone. We argue that SNARC‐like effects can occur for magnitudes not clearly characterized by overlearned ordinality and that magnitude can prevail on order, when the two are pitted against each other. Finally, we propose that different interpretations of the role of order and magnitude depend on the interaction of stimulus properties and task demands. (shrink)

La raccolta di contributi analizza alcuni dei temi più significativi dell’opera dello psicologo e filosofo Paolo Bozzi.

In virtue of Fitch-Church proof, also known as the knowability paradox, we are able to prove that if everything is knowable, then everything is known. I present two ‘onto-theological’ versions of the proof, one concerning collective omniscience and another concerning omnificence. I claim these arguments suggest new ways of exploring the intersection between logical and ontological givens that is a grounding theme of religious thought. What is more, they are good examples of what I call semi-paradoxes: apparently sound arguments whose (...) conclusion is not properly unacceptable, but simply arguable. (shrink)

Abstract – In this paper I reconstruct the nature, origins and survivals of the divide between ‘analytic’ and ‘continental’ tradition—the famous dualism which affected the development of philosophy in the second half of the XX century. I also present a theory of it, stressing that its intra-philosophical causes are to be found in the mutual resistance between critical (transcendental) and semantic (logical) approaches in philosophy. I conclude by noting that good philosophers (more or less knowingly) are and have always been (...) sensitive to the transcendental and logical aspects of the philosophical work. (shrink)

The article tries to outline a general theory of context, by answering four questions: 1.why the concept of context is important? 2. what is usually meant by this term? 3. which metaphysical reasons have led to the relevance of context, in any tendency of contemporary philosophy? 4. which are the reasons, limits and mistakes of negative contextualisms ? The basic idea is that the concept of context is a good opportunity, more than a thread or limit, for philosophical theory.

Esistono metodi filosofici? L’articolo si propone di rispondere alla domanda dapprima mettendo in discussione l’idea che la filosofia sia un’attività ‘extrametodica’, poi esaminando i principali metodi e tecniche messi a punto dalla filosofia contemporanea. Si perviene così a una definizione di filosofia come tentativo di risolvere problemi ‘fondamentali’, che, perciò, procede servendosi di diversi metodi, ciascuno dei quali basato su diverse ‘supervalutazioni’ di tesi relative a concetti tipici, quali ‘realtà’, ‘verità’, ‘conoscenza’.Are there philosophical methods? The article tries to answer this (...) question, at first by discussing the idea of philosophy as an ‘extra-methodical’ activity, then by examining the principal techniques and methods worked out in contemporary philosophy. A definition of philosophy as an attempt to solve ‘fundamental’ problems is also assumed. Such an attempt, is argued, is usually developed by using different methods, each of them depending on different ‘supervaluations’ of theses concerning reality, truth, knowledge, and other typically philosophical concepts.

Over the course of his career, Gianni Vattimo has assumed a number of public and private identities and has pursued multiple intellectual paths. He seems to embody several contradictions, at once defending and questioning religion and critiquing and serving the state. Yet the diversity of his life and thought form the very essence of, as he sees it, the vocation and responsibility of the philosopher. In a world that desires quantifiable results and ideological expediency, the philosopher becomes the vital interpreter (...) of the endlessly complex. As he outlines his ideas about the philosopher's role, Vattimo builds an important companion to his life's work. He confronts questions of science, religion, logic, literature, and truth, and passionately defends the power of hermeneutics to engage with life's conundrums. Vattimo conjures a clear vision of philosophy as something separate from the sciences and the humanities but also intimately connected to their processes, and he explicates a conception of truth that emphasizes fidelity and participation through dialogue.

A new idea of ‘contradictory Christology’ has been recently advanced by JC Beall (The contradictory Christ. Oxford University Press, Oxford, 2021a). This paper does not enter the debate whether Christ double nature instantiates a contradiction or does not. It aims to point out a possible view about the Christological problem similar to Beall’s view but more focused on the metaphysical consequences of admitting a treatment of the Christological paradox in dialetheic terms, as a case of ‘true contradiction’. In Beall’s account, (...) the glut-theoretic approach can improve the conception of logic presupposed in theological discussions, giving new suggestions for the development of an updated ‘logic of Christology’. I move in the other direction, exploring whether the philosophical reflection on Christology could give new insights for paraconsistency and the study of inconsistencies in general. More specifically, I claim that the idea of the unity of contradictories in Christ’s being both divine and human may give some support to the idea of conjunctive paraconsistency, whereby true conjunctions of contradictories do not admit of Simplification. After an introduction which presents the main argument, I summarize the theory of conjunctivism in paraconsistency, then I focus on the (pseudo) Athanasian Creed, wherein the two natures – one person principle is defended against monophysism.
