A quite remarkable book which, now having read, has immediately become a noticable portion of the furniture of my mind... A fine intoduction (for me) to the modernist ethic and the modernist aesthetic... which I've been seeking to understand (with quite some difficulty) for the past two-plus years.
All the secondary literature I've read on Modernism was essentially worthless. Since there is no thread, there really is no thesis; and hence, no real way to approach it via "scholarship". One simply has to go to the primary texts and to the art works themselves.
