"What I mean is that the idea of detached bodies floating in space, of different sizes and densities, perhaps of different colors and temperatures, and surrounded and interlarded with wisps of gaseous condition, and some at rest, while others move in peculiar manners, seems to me the ideal source of form."

“It was more or less directly as a result of my visit to Piet Mondrian’s studio in 1930, and the sight of all his rectangles of color deployed on the wall, that my first work in the abstract was based on the concept of stellar relationships. Since then there have been variations from this theme, but I always seem to come back to it, in some form or other. For though the lightness of a pierced or serrated solid or surface is extremely interesting the still greater lack of weight of deployed nuclei is much more so.”

“I think that at that time and practically ever since, the underlying sense of form in my work has been the system of the Universe, or part thereof. For that is a rather large model to work from.”

“It is a matter of harmonizing these movements, thus arriving at a new possibility for beauty.”

“To me the most important thing in composition is disparity. Thus black and white are the strong colors, with a spot of red to mark the other corner of a triangle which is by no means equilateral, isosceles, or right. To vary this still further use yellow, then, later, blue. Anything suggestive of symmetry is decidedly undesirable, except possibly where an approximate symmetry is used in a detail to enhance the inequality with the general scheme.”
