It makes no difference whether a work is naturalistic or abstract; every visual expression follows the same fundamental laws.

Every art expression is rooted fundamentally in the personality and temperament of the artist.

What goes on in abstract art is the proclaiming of aesthetic principles... It is in our own time that we have become aware of pure aesthetic considerations. Art never can be imitation.

When the impulses which stir us to profound emotion are integrated with the medium of expression, every interview of the soul may become art. This is contingent upon mastery of the medium.

Creation is dominated by three absolutely different factors: First, nature, which works upon us by its laws; second, the artist, who creates a spiritual contact with nature and his materials; third, the medium of expression through which the artist translates his inner world.

An idea can only be materialized with the help of a medium of expression, the inherent qualities of which must be surely sensed and understood in order to become the carrier of an idea.
