Famous quotes containing the words primitive and/or pit:
“Look at this poet William Carlos Williams: he is primitive and native, and his roots are in raw forest and violent places; he is word-sick and place-crazy. He admires strength, but for what? Violence! This is the cult of the frontier mind.”
—Edward Dahlberg (1900–1977)
“Not Chaos, not
The darkest pit of lowest Erebus,
Nor aught of blinder vacancy, scooped out
By help of dreams can breed such fear and awe
As fall upon us often when we look
Into our Minds, into the Mind of Man.”
—William Wordsworth (1770–1850)
