I have just been thinking that the Blaue Reiter (Blue Rider) does not really represent my work. I have always been convinced that other things of mine are more important... Narcism, fake heroism, and blindness have a lot to answer for, in the Blaue Reiter. All those high-sounding words about the birth of a great spiritual moment still resounding in my ears. Kandinsky can air his personal opinion about that or any other revolution he cares to mention. But I dislike the whole thing.... Take my advice – work, and don't spent so much time thinking about blue riders or blue horses.
