Famous quotes containing the words ephemeral and/or streams:
“As man, as beast, as an ephemeral fly begets, Godhead begets Godhead,
For things below are copies, the Great Smaragdine Tablet said.
Yet all must copy copies, all increase their kind....”
—William Butler Yeats (1865–1939)
“The wilderness experiences a suddent rise of all her streams and lakes. She feels ten thousand vermin gnawing at the base of her noblest trees. Many combining drag them off, jarring over the roots of the survivors, and tumble them into the nearest stream, till, the fairest having fallen, they scamper off to ransack some new wilderness, and all is still again.”
—Henry David Thoreau (1817–1862)
