Sorites, curry and suitable models
Full text linkIn this paper we present two new approaches for dealing with semantic paradoxes and soritical predicates based on fuzzy logic. We show that both of them have conceptual advantages over the more traditional Łukasiewicz approach, and that the second one even avoids standard proofs of w-inconsistency.Fil: Da Re, Bruno.

Structural Weakening and Paradoxes
No full textRecently, several authors have pointed out that substructural logics are adequate for developing naive theories that represent semantic concepts such as truth. Among them, three proposals have been explored: dropping cut, dropping contraction and dropping reflexivity. However, nowhere in the substructural literature has anyone proposed rejecting the structural rule of weakening, while accepting the other rules. Some theorists have even argued that this task was not possible, since weakening plays no role in the derivation of semantic paradoxes. In this article, I introduce a theory for naive truth based on the logic resulting from dropping the rule of weakening from classical logic, and maintaining the other structural rules.Fil: Da Re, Bruno.

Contraction, Infinitary Quantifiers, and Omega Paradoxes
Full text linkOur main goal is to investigate whether the infinitary rules for the quantifiers endorsed by Elia Zardini in a recent paper are plausible. First, we will argue that they are problematic in several ways, especially due to their infinitary features. Secondly, we will show that even if these worries are somehow dealt with, there is another serious issue with them. They produce a truth-theoretic paradox that does not involve the structural rules of contraction.Fil: Da Re, Bruno. Instituto de Investigaciones Filosóficas - Sadaf; Argentina.

Paraconsistencia Total
Full text linkDentro del conjunto de las lógicas no clásicas, las lógicas paraconsistentes han suscitado de manera particular el interés de diversos filósofos. Además de las definiciones tradicionales, en los últimos años, se han propuesto nuevas maneras de caracterizar a la paraconsistencia. Lo que tienen en común todas estas definiciones es que alguna forma de la regla o de la metarregla de explosión debe ser rechazada. En este artículo, presentaré dichas definiciones y evaluaré el rol que juegan la negación y la transitividad en ellas. Finalmente, propondré una nueva caracterización de la paraconsistencia, la que llamaré paraconsistencia total y mostraré que la regla de monotonía juega un rol crucial en todas las presentaciones de dicho concepto.In the context of non-classical logics, many philosophers have been particularly interested in the paraconsistent logics. In addition to traditional definitions, in recent years, new ways of characterizing the notion of paraconsistency have been proposed. In all of these definitions the rule or the meta-rule of explosion is abandoned. In this article, I present those definitions and evaluate the role that the negation and the transitivity play in each of them. Finally, I propose a new definition of paraconsistency which I call total paraconsistency and show that the rule of weakening plays a crucial role in all of the characterizations of such a concept.Fil: Da Re, Bruno.

The Substructural Solution to Paradoxes and the Problem of the Dependence
Full text linkEn los últimos años se han desarrollado diversas soluciones subestructurales a las paradojas semánticas. En particular, se han postulado teorías no transitivas, no contractivas, no reflexivas y, recientemente, no monotónicas. Sin embargo, cuando dichas soluciones son presentadas mediante cálculos de secuentes surge el problema de la dependencia . En pocas palabras, este problema consiste en que no es posible separar las reglas estructurales de la formulación de las otras reglas del cálculo. En este artículo, presentaré este problema y mostraré que, de hecho, es posible construir un cálculo que no contiene ninguna regla estructural de manera explícita y que, sin embargo, resulta trivial al agregarle un predicado veritativo transparente con ciertos axiomas. Luego, delimitaré los alcances de dicho problema, concluyendo que la metodología correcta para seleccionar una solución subestructural a las paradojas semánticas debe basarse en argumentos filosóficos y, tal vez, en un estudio empírico sobre el fenómeno de la paradojicidad y no en la comparación de derivaciones en cálculos particulares.In past years, several substructural solutions to semantical paradoxes have been developed. In particular, nontransitive, noncontractive, nonmonotonic and nonreflexive theories have been proposed. However, when such solutions are presented using sequent-calculi it emerges what I call the problem of the dependence. In a nutshell, this problem consists in that it’s not easy (or sometimes even possible) to distinguish between the structural rules and the other rules of the calculus. In this article, I will present in detail this problem and I show that even worst there is a calculus such that it doesn’t contain any structural rule but cannot nontrivially handle semantical vocabulary. Finally, I will delimit this problem and I will conclude that the correct methodology for preferring one specific substructural theory should be based on philosophical arguments (or in some case, on empirical bases), but not in the comparison between derivations in particular calculi.Fil: Da Re, Bruno.

Metainferential Paraconsistency
Full text linkIn this article, our aim is to take a step towards a full understanding of the notion of paraconsistency in the context of metainferential logics. Following the work initiated by Barrio et al (2018), we will consider a metainferential logic to be paraconsistent whenever the metainferentialversion of Explosion (or meta-Explosion) is invalid. However, our contribution consists in modifying the definition of meta-Explosion by extending the standard framework and introducing a negation for inferences and metainferences. From this new perspective, Tarskian paraconsistent logics such asLP will not result to be metainferentially paraconsistent, in contrast to, for instance, non-transitive logics like ST. Finally, we will end up by defining a logic which is metainferentially paraconsistent in every level, and discussing whether this logic is uniform through translations.Fil: Da Re, Bruno.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Non-reflexive Nonsense: Proof-Theory for Paracomplete Weak Kleene Logic
No full textOur aim is to provide a sequent calculus whose external consequence relation coincides with the three-valued paracomplete logic `of nonsense´ introduced by Dmitry Bochvar and, independently, presented as the weak Kleene logic K3W by Stephen C. Kleene. The main features of this calculus are (i) that it is non-reflexive, i.e., Identity is not included as an explicit rule (although a restricted form of it with premises is derivable); (ii) that it includes rules where no variable-inclusion conditions are attached; and (iii) that it is hybrid, insofar as it includes both left and right operational introduction as well as elimination rules.Fil: Da Re, Bruno.
