The unprinted manuscript is published exclusively for the first time on this website. It has been edited several times and will continuously be updated. In this regard, chapters 1 and 2 are complete, although some small changes or corrections may still be made.

It should be taken into consideration that the author did not write a scientific treatise but shared his own thoughts as an artist. They are based on his study of artworks of other artists combined with his own inner experiences during his creative process. He completed his manuscript in 1981.
