Von den mannigfachen Ausdrücken der „intentionalen Inexistenz“ bei Franz Brentano

In this article I provide an overview of the many different terms that Brentano sometimes uses as synonyms or as explanations for “intentional inexistence”. The many terms associated with intentional inexistence appear in many different contexts, and we can conclude that Brentano uses these terms primarily to describe a property that is accidental and dependent on the subject from which it arises and with which it passes away. Ontologically, both properties and substances exist, but the former requires a substance (the subject) for its existence. A mental act is to be considered as a first-order property, whereas the content (or part of the mental act) can be understood as an accident of that accident.
