4.3 Cartesian Dualism

A series of lectures delivered by Peter Millican to first-year philosophy students at the University of Oxford. The lectures comprise of the 8-week General Philosophy course, delivered to first year undergraduates. These lectures aim to provide a thorough introduction to many philosophical topics and to get students and others interested in thinking about key areas of philosophy. Taking a chronological view of the history of philosophy, each lecture is split into 3 or 4 sections which outline a particular philosophical problem and how different philosophers have attempted to resolve the issue. Individuals interested in the 'big' questions about life such as how we perceive the world, who we are in the world and whether we are free to act will find this series informative, comprehensive and accessible.
