“My brush stroke has no system at all. I hit the canvas with irregular touches of the brush, which I leave as they are. Patches of thickly laid-on color, spots of canvas left uncovered, here and there portions that are left absolutely unfinished, repetitions, savageries; in short, I am inclined to think that the result is so disquieting and irritating as to be a godsend to those people who have fixed preconceived ideas about technique.”

Vincent Van Gogh in his letters
