What is the main conflict in Silence; Lectures and Writings by John Cage?

This collection of essays and presentations by noted composer and musical innovator John Cage attempts to capture on paper both the intellectual and stylistic creativity with which he approached his work. In both the themes of the collection and the internal arrangement of the individual pieces, the author explores the nature of music, music's relationship to sound, and the value of incorporating randomness into what had previously been an ordered, carefully considered art form.
