Famous quotes containing the words dark and/or matter:
“The Past—the dark unfathom’d retrospect!
The teeming gulf—the sleepers and the shadows!
The past! the infinite greatness of the past!
For what is the present after all but a growth out of the past?”
—Walt Whitman (1819–1892)
“[A] Dada exhibition. Another one! What’s the matter with everyone wanting to make a museum piece out of Dada? Dada was a bomb ... can you imagine anyone, around half a century after a bomb explodes, wanting to collect the pieces, sticking it together and displaying it?”
—Max Ernst (1891–1976)
