Abstract

Bäck’s thesis is that Aristotle accepts what Bäck calls the aspect theory of predication: the theory that all well-formed affirmative statements in the present tense assert that their subjects now exist. “Fido is brown” means that Fido exists brownly. Thus Aristotle’s copula is really a certain sort of use of the “is” of existence.. On Bäck’s view Aristotle’s ten categories, or “ways in which being is said,” turn out to be ten kinds of way for a subject to exist.
