Famous quotes containing the words primitive and/or pit:
“Every modern male has, lying at the bottom of his psyche, a large, primitive being covered with hair down to his feet. Making contact with this Wild Man is the step the Eighties male or the Nineties male has yet to take. That bucketing-out process has yet to begin in our contemporary culture.”
—Robert Bly (b. 1926)
“Come gather round me players all:
Come praise Nineteen-Sixteen,
Those from the pit and gallery
Or from the painted scene
That fought in the Post Office
Or round the City Hall....”
—William Butler Yeats (1865–1939)
