Famous quotes containing the words ephemeral and/or streams:
“We now demand the light artillery of the intellect; we need the curt, the condensed, the pointed, the readily diffused—in place of the verbose, the detailed, the voluminous, the inaccessible. On the other hand, the lightness of the artillery should not degenerate into pop-gunnery—by which term we may designate the character of the greater portion of the newspaper press—their sole legitimate object being the discussion of ephemeral matters in an ephemeral manner.”
—Edgar Allan Poe (1809–1845)
“Unwearied still, lover by lover,
They paddle in the cold
Companionable streams or climb the air;
Their hearts have not grown old;”
—William Butler Yeats (1865–1939)
