[FERENC KOVACS <f.kovacs@xxxxxxxxxxxxxx>]

IN THE SAME DOCUMENT

Recursive Definitions
(Advanced material) By a "direct ancestor" we mean one's "parents, grandparents, great-grandparents, etc." More formally, we might write:

"x is a direct ancestor of y" =_df "x is a parent of y; or x is a parent of a parent of y; or x is a parent of a parent of a parent of y; etc."

My comments: is it not the referent that the definition is about?C ompare with the statement in the front above: quote

 

For example, the term, "pain", is defined, but pain itself is not defined. We define only terms, never their referents. end of quote
