ABSTRACT
Meinong’s most famous book is called On Assumptions.1 The topic indicated by its title hardly warrants its fame. From an ontological point of view, the discovery of one more kind of mental act is not very exciting. But the title is somewhat misleading. What Meinong discovers is not just another kind of mental act, but another ontological category, the category of states of affairs. He calls these new entities ‘objectives.’ From now on, Meinong’s ontology distinguishes between the two basic categories of objects and objectives.
