What is the author's style in Silence; Lectures and Writings by John Cage?

The author is clearly writing from a place of profound personal belief and philosophy—the book creates the very clear impression that the author has lived and worked with an intention and commitment to come to a new, ever-evolving understanding of the relationship between music and sound. While the book's sense of autobiography extends only into revelations of present perspective (there is little or no sense of how, in the author's past, that perspective came into being), the fact remains that the book's philosophy is lived and practiced, not just considered and analyzed. In other words, the author has actually done the things he talks about, applied the theories he espouses, and is apparently continuing to do so even as he is writing.
