Koncepcja istnienia według Franciszka Brentana

Abstract

The paper presents Franz Brentano’s theory of existence. In particular, we discuss Brentano’s arguments for the thesis that existence is not a predicate. The most important role in the defence of such a concept of existence is played by the theory of judgment, according to which, judging consists in the acceptance or rejection of the object of presentation. However, the analysis of Brentano’s arguments for the existential theory of judgment demonstrates that there are no sufficient reasons to accept Brentano’s thesis concerning the nature of existence.
