“Mondrian... The constructivists?... They had certainties. They wanted a stable basis to work on, but I’m afraid that that was enormous arrogance on their part. Nothing is stable and no certainties are possible.”

“There is nothing so stable as change.”

“The only certainty is that nothing is certain.”

“Life isn't nearly as stable as we want it to be.”

“There is nothing stable in the world; uproar's your only music.”

“The one unchangeable certainty is that nothing is certain or unchangeable.”
