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)
“A tiger in a deep pit can be bullied by dogs.”
—Chinese proverb.
