"I went across the fields to avoid the straight highways, along the firing lines where people were shooting at a small wooded hill, which is now covered with wooden crosses and lines of graves instead of spring flowers."

"I believe the reason I love painting so much is that it forces one to be objective."

"I am seeking for the bridge which leans from the visible to the invisible through reality."

"Art is creative for the sake of realization, not for amusement... for transfiguration, not for the sake of play."

"I passed blindly many things which belong to real and political life."

"Height, width, and depth are the three phenomena which I must transfer into one plane to form the abstract surface of the picture, and thus to protect myself from the infinity of space."

"I hardly need to abstract things, for each object is unreal enough already, so unreal that I can only make it real by means of painting."

"I believe that the reason why I love painting so much is that it forces one to be objective. There is nothing I hate more than sentimentality."

"One of my problems is to find the self."

"What I want to show in my work is the idea which hides itself behind so-called reality."

"It was so wonderful outside that even the wild senselessness of this enormous death, whose music I hear again and again, could not disturb me from my great enjoyment!"
