Logic and Ontology

Resumo

In view of the presertt state of development of non cktssicallogic, especially of paraconsistent logic, a new stand regardmg the relatzons between logtc and ontology is deferded In a parody of a dicturn of Quine, my stand may be summarized as follows To be is to be the value of a vanable a specific language with a given underlymg logic Yet my stand differs from Qutne's, because, among other reasons, I accept some first order heterodox logIcs as genutne alternatwes to ciassical logic I aiso discuss some questions of non classical logic to substantzate my argument, and suggest that rny position complements and extends some uleas advanced by L Apostei.
