|"Interior Artwork2" collage by Lani, textures by FlyPaper.|
Here are a few of the lessons in a nutshell, but for more, please go to his original work on line, for free (free stuff makes for the happy artist), Concerning the Spiritual in Art (1911).
Express your inner world, not the latest artistic trends.
Approach color as a window into the human soul.
By creating original work, you will further the cause of humanity.
"[Art is] ...the mysterious expression of the mysterious..." (from Autobiography, Wassily Kandinsky, 1918.)
The commonality here between Kandinsky and Edith, is the emphasis on the interior life. Edith talked about that we were losing touch with our inner life. That in order to be true to ourselves, in order to be original, we needed to be able to access our inner life. Being a student of Bauhaus via Friedl Dicker-Brandeis, the way to access the inner life was through a daily art practice.
So if you want to be able to look at the culture you are in and consider if it is aligned with your ideas of justice, creativity, humanity, and not just follow what the culture dictates, you will need to be able to understand your own thinking about these things. You will need to be able to access your interior life.
