“Metaphors of space have always been introduced into painting, the play of fullness and emptiness, volumes, surfaces, light and shade... And, in recent painting, in particular, the notion of 'emptiness' has assumed great significance... This interest in emptiness, in nothingness, is found in many disciplines, in particular in an important sector of modern philosophy. We know, for example, that the philosophers such as Heidegger or Sartre have, at a given moment, made nothingness the center of their thought…”

“The poet…is the man of metaphor: while the philosopher is interested only in the truth of meaning, beyond even signs and names, and the sophist manipulates empty signs…the poet plays on the multiplicity of signifieds.”

“I was not made for the great light that devours, a dim lamp was all I had been given, and patience without end, to shine it on the empty shadows.”

“I frequently leave areas of raw, unprimed canvas unpainted [as in her painting 'Chairman of the Board', 1971].... That 'negative' space has just as active a role as the 'positive' painted space. The negative spaces maintain shapes of their own and are not empty.”

“Having found nothing worth more than emptiness, he leaves space vacant.”

“The spectacle of the sky overwhelms me. I'm overwhelmed when I see, in an immense sky, the crescent of the moon, or the sun. There, in my pictures, tiny forms in huge empty spaces. Empty spaces, empty horizons, empty plains - everything which is bare has always greatly impressed me.”

“There is no such thing as an empty space or an empty time. There is always something to see, something to hear. In fact, try as we may to make a silence, we cannot.”

“As human beings, we have a natural compulsion to fill empty spaces.”

“I have nothing to give but my heart so full and these empty hands."

"They're not empty now.”

“Nor is anything empty: For what is empty is nothing. What is nothing cannot be.Nor does it move; for it has nowhere to betake itself to, but is full. For if there were aught empty, it would betake itself to the empty. But, since there is naught empty, it has nowhere to betake itself to.”
