Abstract

The notion of state of affairs was introduced as the complexly signifiable in the Late Scholasticism and rediscovered by Logicians like Bolzano and Frege. While Bolzano and Frege were primarily interested in the nature of objective truths students of Brentano, among others Meinong, Twardowski and Husserl, developed similar concepts starting out with an interest in the nature of mental acts and judgement. Both Frege's and Meinong's conceptions face similar problems concerning complex referents which are diagnosed to stem from confusions of complexes of properties with complex properties.
