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)
“Violence does, in truth, recoil upon the violent, and the schemer falls into the pit which he digs for another.”
—Sir Arthur Conan Doyle (1859–1930)
