According to logical non-necessitarianism, every inference may fail in some situation. In his defense of logical monism, Graham Priest has put forward an argument against non-necessitarianism based on the meaning of connectives. According to him, as long as the meanings of connectives are fixed, some inferences have to hold in all situations. Hence, in order to accept the non-necessitarianist thesis one would have to dispose arbitrarily of those meanings. I want to show here that non-necessitarianism can stand, without disposing arbitrarily of the meanings of connectives, based on a minimalist view on the meanings of connectives

It has been claimed that contracting connectivesContracting connective are conditionalsConditional. Our modest aim here is to show that the conditional-like features of a contracting connectiveContracting connective depend on the defining features of the conditionalConditional in a particular logic, yes, but they also depend on the underlying notion of logical consequence and the structure of the collection of truth values. More concretely, we will show that under P-consequenceP-consequence and suitable satisfiability conditions for the conditionalConditional, conjunctionsConjunction are contracting connectivesContracting connective for some logics without thereby being conditional-ish.

A contra-classical logic is a logic that, over the same language as that of classical logic, validates arguments that are not classically valid. In this paper I investigate whether there is a single, non-trivial logic that exhibits many features of already known contra-classical logics. I show that Mortensen’s three-valued connexive logic _M3V_ is one such logic and, furthermore, that following the example in building _M3V_, that is, putting a suitable conditional on top of the \(\{\sim, \wedge, \vee \}\) -fragment of _LP_, one can get a logic exhibiting even more contra-classical features.

A menudo se discute cómo cifrar el alcance de la herencia de Kant en la metafísica de Schopenhauer. Del corazón y sustancia de su Tebas de las mil puertas, la ética, Aramayo cree oportuno tomarla como una radicalización del formalismo kantiano. A mi juicio, para delimitar qué hay de continuidad, y qué de ruptura, es necesario hacer un examen atento del puente que conduce de uno a otro. En este sentido, la crítica dedicada a Kant en Sobre el fundamento de la moral no ocupa un lugar accidental en su pensamiento único, pues contiene lo que le falta al apéndice crítico de su obra principal respecto al objeto que nos ocupa. Desde el análisis de conceptos hasta las lecturas genealógicas que se presentan en esta polémica, un mismo propósito subyace: la depuración del concepto de racionalidad práctica como solución a las aporías y los escollos del legado ético kantiano.

Esta nota, que resume una conferencia pronunciada en octubre de 2011 en las Jornadas Nacionales de Liturgia de Barcelona, analiza y estudia la aportación de Sacramentum Caritatis al importante tema de la participación activa de los fieles en la liturgia. El autor concluye, entre otras cosas, que la sutil distinción entre condiciones personales para la participación y la participación misma enriquece el concepto de actuosa participatio acentuando sus dimensiones más hondas desde el punto de vista de la antropología sacramental.

Francez has suggested that connexivity can be predicated of connectives other than the conditional, in particular conjunction and disjunction. Since connexivity is not any connection between antecedents and consequents—there might be other connections among them, such as relevance—, my question here is whether Francez’s conjunction and disjunction can properly be called ‘connexive’. I analyze three ways in which those connectives may somehow inherit connexivity from the conditional by standing in certain relations to it. I will show that Francez’s connectives fail all these three ways, and that even other connectives obtained by following more closely Wansing’s method to get a connexive conditional, fail to be connexive as well.

The presence of the past is of prime importance in today's Mexican society. According to José Fuentes Mares, among the “peoples of the world the Mexican is the one who lives history the most”. With regard to the unsatisfactory relations between Mexico and North America, the journalist Alan Riding asks himself: “How can a people who relish the past to the point of intoxication understand another that looks constantly to the future?” In the Republic of Mexico, according to him, “the entire past of the country throws a dense shadow over the present”. Conforming to a universal custom, every country divides its present past into four groups (survival, residues, memories and history), but in few nations are the four groups as copious as in this one. Although Mexico is rapidly shedding many old customs and is selling residual objects to foreign collectors on the sly, its historical treasure is still enormous, perhaps the largest in the world.

Schools are an essential part of students’ lives and can promote and facilitate their well-being. Although research on well-being among school-aged children and adolescents has distinguished subjective well-being from social well-being, very few studies examined student’s social well-being at school. SWS is understood as students’ valuation of the circumstances and functioning of their school. This framework posits that the context of the schools can shape students’ perception of feeling integrated and making significant contributions to their schools. However, not much is known regarding the joint contribution of individual, family, and school characteristics to students’ SWS. This study analyzed these joint contributions in a nationally representative sample of 6,389 children and adolescents enrolled in 5th–11th grades. Findings show that being female and younger were individual predictors of SWS. Students’ satisfaction with their family and fewer changes of schools were also significant contributors. When students’ perceptions of their schools were incorporated, the individual and family characteristics decreased or lost significance. In the full model, the highest contribution to SWS was explained by the school-level aggregated perception of school climate. These findings call for integrated policies and practices to foster students’ sense of belonging, feeling integrated, and contribution to their schools, with a focus on school-level interventions to improve SWS through positive and engaging school climates that foster students’ sense of agency.

In her, Martínez-Ordaz puts forward an argument whose conclusion pretends to be a dilemma for selective realists: either selective realists cannot rule true contradictions out or the usual characterization of selective realism is incomplete. Then she argues that one should take the second horn and complete such a characterization with some logical constraints. In this note, I will defend that her argument for the dilemma is flawed at several steps and, moreover, that the dilemma is not dangerous and that her proposed completion of selective realism is not needed.

Alberic of Paris put forward an argument, ‘the most embarrassing of all twelfth-century arguments’ according to Christopher Martin, which shows that the connexive principles contradict some other logical principles that have become deeply entrenched in our most widely accepted logical theories. Building upon some of Everett Nelson’s ideas, we will show that the steps in Alberic of Paris’ argument that should be rejected are precisely the ones that presuppose the validity of schemas that are nowadays taken as some of the most trivial logical truths: (A∧B) → A and (A∧B) → B, i.e. Simplification.
