Aristotle's Syllogistic and Core Logic

Neil Tennant
2014 History and Philosophy of Logic  
The syllogisms in all four figures are re-proved in the binary system, and are thereby revealed as all on a par with each other.  ...  First I regiment the syllogisms in the Gentzen-Prawitz system of natural deduction, using the universal and existential quantifiers of standard first-order logic, and the usual formalizations ofAristotle's  ...  Introduction rules and parallelized elimination rules for the new binary quantifiers in a system of natural deduction In order for Qx(ϕ, ψ) (Q = A, E, I, O) to be a sentence, both ϕ and ψ must have x as  ...

Cognitive Binary Logic - The Natural Unified Formal Theory of Propositional Binary Logic

Nicolaie Popescu-Bodorin, Luminita State
2011 arXiv   pre-print
It is also shown here that Cognitive Binary Logic is a self-described theory in which the Liar Paradox is deconstructed.  ...  This paper presents a formal theory which describes propositional binary logic as a semantically closed formal language, and allows for syntactically and semantically well-formed formulae, formal proofs  ...  Gentzen's natural deduction system (sequent calculus) [1] , completeness [6] , consistency (soundness) [6] -all of them considered in the context of propositional binary logic, equivalence relations  ...

Deductive Systems in Traditional and Modern Logic

Alex Citkin, Urszula Wybraniec-Skardowska
2020 Axioms  
Since its inception, logic has studied the acceptable rules of reasoning, the rules that allow us to pass from certain statements, serving as premises or assumptions, to a statement taken as a conclusion  ...  with a new binary connective that expresses the identity of two statements.  ...  In [8] , A. Citkin studies the deductive systems with multiple conclusion rules which admit the introduction of meta-disjunction.  ...

A Binary Quantifier for Definite Descriptions in Intuitionist Negative Free Logic: Natural Deduction and Normalisation

Nils Kürbis
2019 Bulletin of the Section of Logic  
This paper presents a way of formalising definite descriptions with a binary quantifier ℩, where ℩x[F, G] is read as 'The F is G'.  ...  Procedures for removing maximal formulas of the form ℩x[F, G] are given, and it is shown that deductions in the system can be brought into normal form.  ...  In this paper, I investigate the binary quantifier ι in the context of a system of natural deduction for intuitionist negative free logic.  ...

On the Paths of Categories [chapter]

Kosta Došen
2015 Advances in Proof-Theoretic Semantics  
To determine what deductions are it does not seem sufficient to know that the premises and conclusions are propositions, or something in the field of propositions, like commands and questions.  ...  It seems equally, if not more, important to know that deductions make structures, which in mathematics we find in categories, multicategories and polycategories.  ...  Acknowledgments Work on this paper was supported by the Ministry of Education, Science and Technological Development of Serbia, while the Alexander von Humboldt Foundation has supported the presentation of a  ...

Definite Descriptions in Intuitionist Positive Free Logic

Nils Kürbis
2020 Logic and Logical Philosophy  
The system is shown to have desirable proof-theoretic properties: it is proved that deductions in it can be brought into normal form.  ...  This paper presents rules of inference for a binary quantifier I for the formalisation of sentences containing definite descriptions within intuitionist positive free logic.  ...  Two referees for this journal also made helpful comments on a previous version. Its final version was prepared while I was an Alexander von Humboldt fellow at the University of Bochum.  ...

Existence and Identity in Free Logic: A Problem for Inferentialism?

Neil Tennant
2007 Mind  
First, it argues that the method of natural deduction idealizes the essential details of correct informal deductive reasoning.  ...  The final part of the investigation brings out an underlying order in a basic family of free logics.  ...  For whatever reasonable system of free logic one chooses, there is a natural-deduction system for it, and the rules of inference involved ought to be 'capturing' the meanings of the logical operators involved  ...
