help with citation for "a work of art opens a void"

Hi,
I have a quote of Foucault and I would like to know where it came
from--can anyone help me find this?
"A work of art opens a void, a moment of silence, a question without
answer, provokes a breach without reconciliation where the world is
forced to question itself."

I appreciate your help!
