"Received your letter and, almost at the same time, the long text at which I was overjoyed. You no doubt know that you are the only person in the world to have put together the gestation of the glass in all its detail, including even the numerous intentions which were never executed . Your patient work has enabled me to relive a period of long years during which the notes were written for the 'Green Box' at the same time as the Glass was taking shape.

“..we must remember that this 'art coefficient' is a personal expression of art 'à l'état brute', that is, still in a raw state, which must be 'refined' as pure sugar from molasses, by the spectator; the digit of this coefficient has no bearing whatsoever on his verdict.. ..the role of the spectator is to determine the weight of the work on the aesthetic scale.”
