“An artist must either give up art or develop.”

“...art must must carry man's craving for the ideal, must be an expression of his reaching out towards it; that art must give man hope and faith. And the more hopeless the world in the artist's version, the more clearly perhaps must we see the ideal that stands in opposition - otherwise life becomes impossible! Art symbolises the meaning of our existence.”

“The soul of an artist cannot be muted indefinitely. It must either be expressed or it will consume the host.”

“Either everything in man can be traced as a development from below, or something must come from above. There is no avoiding that dilemma: you must be either a naturalist or a supernaturalist.”

“For most people, art is only valuable if other people say it is; and artists are only worthwhile if they are either rich and famous, or dead.”

“Any authentic work of art must start an argument between the artist and his audience.”
