ABSTRACT
In the last chapter, we saw that Meinong defines the theory of entities in terms of the traditional dichotomy between a priori and a posteriori knowledge. What can be known a priori, merely from the nature of the entities involved, that belongs to the theory of entities. Everything else is a matter of empirical knowledge. This characterization of the theory of entities demands a sharp distinction between a priori and a posteriori knowledge, between rational and empirical knowledge. Meinong attempts to clarify the notion of empirical knowledge in his work Über die Erfahrungsgrundlagen unseres Wissens.1
