On the ordinary notion of substance. Reply to abreu zavaleta

Resumo

My proposed mechanism of reference fixing for ordinary natural kind terms in the book Roads to Reference appeals to the ordinary notion of substance. In this note I reply to an objection by Martín Abreu Zavaleta that that notion is too vague to allow for a sufficiently constrained property to become the referent of a given ordinary substance term. I argue that the notion of substance is far less vague than Abreu Zavaleta claims.
