"I don't understand how many painters can be so short-sighted to value art from earlier periods as completely worthless. Every art is an expression of an era and only for that reason already it is interesting. A Rembrandt has gone other ways, but he has certainly also pursued the highest goals. That one can assert: it is not necessary for a painter to have an impression when he is painting an Image, is nonsense. Certainly an artist, if he is really an artist, always has an inner urge to create an Image and thus sees an impression for himself that he may not always be able to explain, because deeper feelings are very difficult to grasp in words, but he has an impression - otherwise he only makes paintings as pure brain work. And intellectual art I can't bear. You can not make abstract art as something on its own. One feel various forms in their inner coherence. For example: when reading a fairy tale I can get the idea to paint a forest in completely abstract forms with motifs of trees. Every abstract form has an inner meaning for me."

“As an artist you can not stand for long in The Netherlands. You must see a lot and talk a lot about everything..”

“The country is very beautiful and painterly one see stimulating color tones; but the more abstract one works, the more one transforms the sketch into combinations.”

“I got the idea to paint people, in the way I see them. From one face I take to my own idea some very characteristic features of it and then I make of the whole a picture in colors and lines, in the way how I meet that person. The whole thing becomes not at all a portrait in the usual sense.. .I have tried to make types, but will built in more and more personal qualities and all that kind of things.. .Everything will be figured out fully abstract of course, it is just a personal feeling and no system at all.”

“All men forget that colors have to radiate to give the big expression.”
