Famous quotes containing the words primitive and/or pit:
“Each structure and institution here was so primitive that you could at once refer it to its source; but our buildings commonly suggest neither their origin nor their purpose.”
—Henry David Thoreau (1817–1862)
“We live in a time which has created the art of the absurd. It is our art. It contains happenings, Pop art, camp, a theater of the absurd.... Do we have the art because the absurd is the patina of waste...? Or are we face to face with a desperate or most rational effort from the deepest resources of the unconscious of us all to rescue civilization from the pit and plague of its bedding?”
—Norman Mailer (b. 1923)
