"One day they will say (because, like it or not, that's how it is) that my physiological shapes are brought about by morbid or erotic sensations (they're already saying so) On the contrary, I hasten to say that they are not even expressive forms but simply plastic ones (in a spatial function) suggested by a shining physiological anatomy rather than a physical one. And what is this physiological anatomy? The function of determining and giving body to shapes, a gesture in the imagination still linked to the causes that prompted it. It is the feeling of the very form of it that I want you to feel (hear)." (27th November 1945)
