Curry’s paradox is well known. The original version employed a conditional connective, and is not forthcoming if the conditional does not satisfy contraction. A newer version uses a validity predicate, instead of a conditional, and is not forthcoming if validity does not satisfy structural contraction. But there is a variation of the paradox which uses “external validity”. And since external validity contracts, one might expect the appropriate version of the Curry paradox to be inescapable. In this paper we show that (...) this is not the case. We consider two ways of formalising the notion of external validity, and show that in both of these the paradox is not forthcoming without the appropriate forms of contraction. (shrink)

Francesco Berto proposed a logic for imaginative episodes. The logic establishes certain (in)validities concerning episodic imagination. They are not all equally plausible as principles of episodic imagination. The logic also does not model that the initial input of an imaginative episode is deliberately chosen.Stit-imagination logic models the imagining agent’s deliberate choice of the content of their imagining. However, the logic does not model the episodic nature of imagination. The present paper combines the two logics, thereby modelling imaginative episodes with deliberately (...) chosen initial input. We use a combination ofstit-imagination logic and a content-sensitive variably strict conditional à la Berto, for which we give a Chellas–Segerberg semantics. The proposed semantics has the following advantages over Berto’s: (i) we model thedeliberate choiceof initial input of imaginative episodes (in a multi-agent setting), (ii) we showframe correspondencesfor axiomatic analogues of Berto’s validities, which (iii) allows thepossibility to disregard axiomsthat might be considered not plausible as principles concerning imaginative episodes. We do not take a definite stance on whether theseshouldbe disregarded but give reasons for why one might want to disregard them. Finally, we compare our semantics briefly with recent work, which aims to model voluntary imagination, and argue that our semantics models different aspects. (shrink)

Model-theoretic proofs of functional completenes along the lines of [McCullough 1971, Journal of Symbolic Logic 36, 15–20] are given for various constructive modal propositional logics with strong negation.

Résumé : Gottfried Hermann (1772-1848) a fait ses études, puis sa carrière d'enseignant et de chercheur à Leipzig. Parmi les philologues classiques allemands de la première moitié du XIXesiècle, il se singularise par l'influence que la philosophie de Kant a exercé sur ses conceptions théoriques dans plusieurs domaines, notamment la métrique.

Paru en 1909 dans les Kant-Studien, « Les deux voies de la théorie de la connaissance » constitue une pièce maîtresse du débat qui opposa le néokantisme à la phénoménologie naissante. Heinrich Rickert, qui fut avec Windelband et Lask l’un des principaux représentants de l’école néokantienne de Heidelberg, y expose de façon claire et synthétique les principes méthodiques qui fondent sa philosophie critique. À travers un dialogue constant avec les Recherches logiques de Husserl, Rickert distingue deux « voies » (...) ou deux méthodes que peut suivre la théorie de la connaissance : la méthode psychologico-transcendantale , correspondant à l’analyse de l’acte de juger, et la méthode logico-transcendantale , correspondant à l’analyse du sens propositionnel. Comment ces deux méthodes s’articulent-elles? Quelle est leur contribution propre au programme critique? Et quelles sont leurs limites respectives? Sur ces questions, la position de Rickert se révèle aussi riche et innovante que celle de Husserl, dont elle diffère sensiblement. L’aspect à la fois polémique et concis de ce texte en fait un document essentiel pour la connaissance de l’école de Heidelberg et, plus généralement, pour l’étude du néokantisme dans son ensemble.

Neinsagen ist die Formel des Protestes. In einer Welt, die zu Protesten Anlaß bietet, scheint es nicht überflüssig, diese Formel zu untersuchen.

In this paper we elaborate a conception of entailment based on what we call the Ackermann principle, which explicates valid entailment through a logical connection between sentences depending on their informational content. We reconstruct Dunn’s informational semantics for entailment on the basis of Restall’s approach, with assertion and denial as two independent speech acts, by introducing the notion of a ‘position description’. We show how the machinery of position descriptions can effectively be used to define the positive and the negative (...) information carried by sentences of a given language and to present a formalized version of the Ackermann principle as an inclusion relationship between the informational contents of the conclusions and the premises of a valid entailment. Being so interpreted, the entailment relation exhibits certain properties, including the property of transitivity. Whereas properties such as Anderson and Belnap’s variable sharing property or Parry’s proscriptive principle are normally presented as imposing a relevance requirement on valid entailment, the suggested formalization of the Ackermann principle supports all of Gentzen’s structural rules, including weakening, a rule that is normally given up in sequent-style proof systems for relevance logics. In this way we propose an Ackermann-inspired explication of the nature of entailment as a relation between the informational contents of sentences. (shrink)
