What is the author's tone in The Book of Tea by Kakuzo Okakura?

In the case of The Book of Tea, tone is highly interdependent on the author's perspective. Okakura is a conservative, a reactionary. He sees the damaging effects of Japanese modernization, and so The Book of Tea is his way to preserve what he perceives to be a crucial part of Japanese heritage, in much the same way that art is preserved in the museums and institutes he has curated.
