I have been to [the gallery] Hagen, saw two Matisses, which enchanted me. A large collection of Japanese masks. Sublime! 'Neue [Künstler] Vereinigung' were hung in a bad light. ... Kandinsky, Jawlensky, Bechteleff and Erbslöh have immense artistic sensibility. But the means of expression are to big for what they have to say. The sound of their voice is so good, so fine, that what is being said get lost. Consequently a human element is missing. They concentrate, too much, I think, on form. There is much to be learnt from their efforts. But early things by Kandinsky, and a few by Jawlensky too, seem a little empty to me. And Jawlensky's heads looked at me a little bit too much with colors. With blue and green. I hope you understand what I mean.
