My wish [c. 1911].... of compiling a book (a kind of Almanac) in which all the contributions should be written by artists. I dreamt primarily of painters and musicians. The ruinous separation of the arts from each other, and of 'Art' from folk-art and from children's art, the distinction between 'Art' and 'Ethnography' [folk-art].... the solid walls erected between phenomena that in my eyes were so closely related, even identical: in a word, the potentialities for synthesis left me no peace. It may well seem strange today [1930] that for a long time I could not find any co-workers or any means to promote this idea..
