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...

1. The label conjunctive paraconsistency has been adopted to mean a consequence relation whereby ‘p and not p’ does not imply ‘p’ and ‘not p’ separately, so that Simplification in case of contradic...

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)

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)

This paper advances a version of the theory whereby logic had deep origins in democracy, by re-reading Gorgias’ Encomium of Helen. Democracy, ‘the government by debate’, called political (and scientific) attention to the inferential abilities of citizens and to politicians’ ability of taking advantage of them. Sophists, in particular, discovered that people’s inferences follow constant repeatable forms, that these forms have impact on choices and decisions concerning public good, and then by dominating them you dominate politics in democracy. With the (...) Encomium Gorgias launched these ideas, so laying the ground for Aristotle’s science of deduction. (shrink)

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)

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.

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.

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.
