69. Peter Gärdenfors: Conceptual spaces, knowledge representation, and semantics

Peter Gärdenfors is an Emeritus Professor at Lund University at the Department of Philosophy. His work is at the intersection of philosophy, cognitive, psychology, and linguistics. In this conversation, we discuss his book Conceptual spaces and many of the topics discussed therein (convexity, prototypes, metrics), whether the theory is falsifiable, how it can explain aspects of semantics and of how children learn, and much more.

BJKS Podcast is a podcast about neuroscience, psychology, and anything vaguely related, hosted by Benjamin James Kuper-Smith.
