I really appreciate your input and frankness, thanks a lot for that. However I still believe Kandinsky absorbed and digested a lot of nutrition from Ninths’s esthetic idea when he cooking up his own theory of Spiritual in Art , especially on his establishment of the belief in the ultimate triumph of the spiritualism over the materialism. As Messer mentioned in his book, in Munich, Kandinsky wrote up a lot of art commentary prose, he liked Nietzsche very much and substantially influenced by Nietzsche in the way of literary style as well as art theory stand.
