Steiner has here transformed the vaporous conceptions of his life, the vapors of what never was and never will be, from their aeriform state to a fine and ethereal substantiality. My Unwritten Books is a gathering of shades, an elegant and eloquent gathering of mind, feeling, and autumnal passion. (...) And that is the lovely irony of this unique little book. None of these unwritten books should have been written. They are better here, as they are, untamed and errant phantoms of a brilliance whose emanations no one mortal lifetime could ever accommodate in full.
