On Boolean modus ponens

open access: yesMathware & soft computing, 1998
An abstract form of modus ponens in a Boolean algebra was suggested in [1]. In this paper we use the general theory of Boolean equations (see e.g. [2]) to obtain a further generalization. For a similar research on Boolean deduction theorems see [3].

Counterfactual Logic and the Necessity of Mathematics [PDF]

open access: yes
This paper is concerned with counterfactual logic and its implications for the modal status of mathematical claims. It is most directly a response to an ambitious program by Yli-Vakkuri and Hawthorne (2018), who seek to establish that mathematics is ...

Credence for Epistemic Discourse [PDF]

open access: yes
Many recent theories of epistemic discourse exploit an informational notion of consequence, i.e. a notion that defines entailment as preservation of support by an information state.

Natural Implication and Modus Ponens Principle

open access: yesLogical Investigations, 2015
In [6] the definition of natural implication was introduced. One of the criteria for naturalimplication is the normality of logical matrix [2, p. 134], a condition sufficient for verification of modus ponens. In this paper two definitions of modus ponens are regarded: in the designation-preserving sense and in the tautologousness-preserving sense ...

Sui controesempi al Modus Ponens

open access: yes, 2011
In McGee (1985) si presentano tre controesempi al modus ponens (MP), e si argomenta di come esistano restrizioni alla validità di questa regola deduttiva. Nel presente articolo, intendo ridiscutere questi tre controesempi a MP mostrando perché non colgono il bersaglio, e presentare altri casi in cui l'applicazione di MP non sembra efficace.

A Canonical Model for Interactive Unawareness [PDF]

open access: yes
Heifetz, Meier and Schipper (2005) introduced a generalized state-space model that allows for non-trivial unawareness among several individuals and strong properties of knowledge. We show that this generalized state-space model arises naturally if states
