To approach the spiritual in art, one will make as little use as possible of reality, because reality is opposed to the spiritual.
It is a task of art to express clear vision of reality.
Cubism did not accept the logical consequences of its own discoveries; it was not developing abstraction towards its own goal, the expression of pure reality.
By the unification of architecture, sculpture and painting a new plastic reality will be created.
The purer the artist's 'mirror' is, the more true reality reflects in it. Overseeing the historical culture of art, we must conclude that the mirror only slowly is purified. Time producing this purifying shows a gradual, more constant and objective image of reality.
abstract art is not the creation of another reality but the true vision of reality.
