"The earth is round, so why to play it square? Beneath the sun and beneath the moon, in the clouds that sail gently by, everything is going round. Children dance in a ring; there is the Tour de France, and the bikes, and the eyes that look at them and frame them on the road.. .You leave your rectangles, your geometrical windows, and you go to the land of circles in action.. ..It's human nature to break through boundaries, to grow, to push towards freedom. Roundness is free; it has no beginning and no end."

“..a yellow square, a red and blue avenue, an Eiffel tower with a camouflaged silhouette.. ..that would all be lit up at night, instead of fireworks. .”

“The concept of Abstract painting is not a passing abstraction, good only for a few initiates, the total expression of a new generation whose necessities it experiences and to all of whose aspirations it constitutes a response.”

“I dispersed my objects in space and got them to hold together by making them radiate forwards, out of the picture. It's all an easy interplay of chords and rhythms made up of foreground and background colours, of conducting lines, of distances and of contrasts.”

“In 1942 when I was in New York, I was struck by the neon advertisements flashing all over Broadway. You are there, you talk to someone, and all of a sudden he turns blue. Then the colour fades - another one comes and turns him red or yellow. The colour – the colour of neon advertising is free; it exists in space. I wanted to do the same in my canvases.”

“I venture out to the great 'sujet'; but, I repeat, my painting always remains object painting; it starts around 1936 with 'Adam et Eve'. My figures humanise themselves further, but I always stick to the pictorial circumstance – no eloquence, no romanticism”

“Isn't it human to go beyond the limits, to grow beyond oneself, to strive toward freedom! The round is free.”
