Famous quotes containing the words primitive and/or pit:
“A township where one primitive forest waves above while another primitive forest rots below,—such a town is fitted to raise not only corn and potatoes, but poets and philosophers for the coming ages. In such a soil grew Homer and Confucius and the rest, and out of such a wilderness comes the Reformer eating locusts and wild honey.”
—Henry David Thoreau (1817–1862)
“the hind
stepped down
into the pit of
the empty
flowerpot”
—William Carlos Williams (1883–1963)
