"For work, one must be hard and thrust outside of oneself what one has lived through."

“I have been through a revolution, and I am convinced that I am no revolutionist. My childhood dreams of dying on the barricades will hardly be fulfilled, because I should hardly mount a barricade now that I know what they were like in reality. And so I know now what an illusion I lived in for so many years. I thought I was a revolutionary and was only an evolutionary. Yes, sometimes I do not know whether I am a socialist at all, whether I am not rather a democrat instead. How good it is when reality tests you to the guts and pins you relentlessly to the very position you always thought, so long as you clung to your illusion, was unspeakably wrong.”

“For the last third of life there remains only work. It alone is always stimulating, rejuvenating, exciting and satisfying.”

“I am gradually approaching the period in my life when work comes first. When both the boys went away for Easter, I hardly did anything but work. Worked, slept, ate and went for short walks. But above all I worked. And yet I wonder whether the "blessing" is not missing from such work. No longer diverted by other emotions, I work the way a cow grazes.”

“My work is not, of course, pure art in the sense that Schmidt-Rottluff's is, but it is art nonetheless... It is all right with me that my work serves a purpose. I want to have an effect on my time, in which human beings are so confused and in need of help.”

“Pacifism simply is not a matter of calm looking on; it is hard work.”

“There must be understanding between the artist and the people. In the best ages of art that has always been the case. Genius can probably run on ahead and seek out new ways. But the good artists who follow after genius — and I count myself among these — have to restore the lost connection once more.”
