This PhD project, funded by the China Research Council, explores some of the decisive steps that led from Plato's and Aristotle's psychology to Brentano's concept of intentionality that still plays a role in modern philosophy of mind.
Intentionality before Brentano: ancient and medieval concepts
Starting from recent interpretations of ancient and medieval theories of mind and perception in terms of 'intentionality', Liu Hao aims at evaluating various definitions of this term, and its (alleged?) presence in ancient and medieval philosophy. In this way Brentano's anchoring of the notion of intentionality in Peripatetic and Scholastic thought is scrutinized for innovations that remain unclarified in modern historiography of philosophy.
