Famous quotes containing the words spring, patent and/or sails:
“I swear to keep the dead upon my mind,/Disdain for all time to be overglad./Among spring flowers, under summer trees./By chilling autumn waters, in the frosts/Of supercilious winter—all my days/I’ll have as mentors those reproving ghosts.”
—Gwendolyn Brooks (b. 1917)
“This is the patent age of new inventions
For killing bodies, and for saving souls,
All propagated with the best intentions.”
—George Gordon Noel Byron (1788–1824)
“As a man-of-war that sails through the sea, so this earth that sails through the air. We mortals are all on board a fast-sailing, never-sinking world-frigate, of which God was the shipwright; and she is but one craft in a Milky-Way fleet, of which God is the Lord High Admiral.”
—Herman Melville (1819–1891)
