  2. Frédéric Goubier & Ernesto Perini-Santos (forthcoming). When the World is Not Enough: Medieval Ways to Deal with the Lack of Referents. Logica Universalis:1-23.
    According to several late medieval logicians, the use the universal quantifier ‘omnis’ creates the requirement that the sentence refers to at least three items—the principle of sufficientia appellatorum. The commitment is such that, when the quota is not fulfilled, one has to import the missing items from the realm of the nonexistent. While the central argument for this principle, whose origin is Aristotle’s De Caelo, stems from the contrast between unrestricted universal quantifiers and binary quantifiers, the discussion is often mixed (...)

  3. Wolfgang Lenzen (forthcoming). Ockham’s Calculus of Strict Implication. Logica Universalis:1-11.
    In his main work Summa Logicae written around 1323, William of Ockham developed a system of propositional modal logic which contains almost all theorems of a modern calculus of strict implication. This calculus is formally reconstructed here with the help of modern symbols for the operators of conjunction, disjunction, implication, negation, possibility, and necessity.

  4. Ana María Mora-Márquez (forthcoming). Boethius of Dacia and Radulphus Brito on the Universal Sign ‘Every’. Logica Universalis:1-19.
    In this article I present the analysis of the syncategorematic term ‘omnis’ in the commentaries on the Topics by the Parisian masters of Arts Boethius of Dacia and Radulphus Brito. I shall focus on the different relations between subject, predicate and particular instances that obtain in universally quantified statements, and in particular on the relations that obtain in universally quantified statements with an empty subject. I also attempt to highlight some continuities and ruptures with respect to this problem in its (...)

  5. Sergei Odintsov & Vladimir Rybakov (forthcoming). Inference Rules in Nelson’s Logics, Admissibility and Weak Admissibility. Logica Universalis:1-28.
    Our paper aims to investigate inference rules for Nelson’s logics and to discuss possible ways to determine admissibility of inference rules in such logics. We will use the technique offered originally for intuitionistic logic and paraconsistent minimal Johannson’s logic. However, the adaptation is not an easy and evident task since Nelson’s logics do not enjoy replacement of equivalences rule. Therefore we consider and compare standard admissibility and weak admissibility. Our paper founds algorithms for recognizing weak admissibility and admissibility itself – (...)

  7. Stephen Read (forthcoming). Paradox, Closure and Indirect Speech Reports. Logica Universalis:1-15.
    Bradwardine’s solution to the the logical paradoxes depends on the idea that every sentence signifies many things, and its truth depends on things’ being wholly as it signifies. This idea is underpinned by his claim that a sentence signifies everything that follows from what it signifies. But the idea that signification is closed under entailment appears too strong, just as logical omniscience is unacceptable in the logic of knowledge. What is needed is a more restricted closure principle. A clue can (...)
