We take a deep dive into Karl Popper’s philosophical ideas about music that he outlines in four chapters in this intellectual autobiography Unended Quest:

• “Music,”
• Speculations about the Rise of Polyphonic Music,”
• “Two Kinds of Music,” and
• “Progressivism in Art, Especially in Music.” 

We are joined by Peter’s brother, Chris Johansen, who is a straight-ahead jazz tenor saxophonist living in NYC. 

We discuss how Popper’s ideas on classical music intersect with Chris’s ideas on jazz, as well as the role of conservatism in music. We examine how Popper’s thinking on music influenced his concept of the 3 worlds and his ideas on such concepts as dogmatism, essentialism, and historicism. 

Plus, you get Bruce's rant about the importance of constraints in music, science, criticism, and Popper's epistemology. Bruce argues that absent at least the attempt to outline epistemological conventions (i.e. constraints) you can't error correct Popper's epistemology and you lose what makes it special.
