Famous quotes containing the words primitive and/or pit:
“The lumberers rarely trouble themselves to put out their fires, such is the dampness of the primitive forest; and this is one cause, no doubt, of the frequent fires in Maine, of which we hear so much on smoky days in Massachusetts.”
—Henry David Thoreau (18171862)
“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)
