Validity in Simple Partial Logic
Daisuke Kachi · Annals of the Japan Association for Philosophy of Science · 2002
Firstly I characterize Simple Partial Logic (=SPL) as a generalization and extension of a certain two-valued logic.Based on that characterization I present two definitions of validity in SPL.Secondly I show that given my characterization these two definitions are more appropriate than other definitions that have been prevalent, since both have some desirable semantic properties that the others lack.
