Year: 1914

Published in 1911, Kandinsky's book compares the spiritual life of humanity to a pyramid -- the artist has a mission to lead others to the pinnacle with his work. The point of the pyramid is those few, great artists. It is a spiritual pyramid, advancing and ascending slowly even if it sometimes appears immobile. During decadent periods, the soul sinks to the bottom of the pyramid; humanity searches only for external success, ignoring spiritual forces. (Summary from Wikipedia)
