Famous quotes containing the word means:
“The aim of every artist is to arrest motion, which is life, by artificial means and hold it fixed so that a hundred years later, when a stranger looks at it, it moves again since it is life. Since man is mortal, the only immortality possible for him is to leave something behind him that is immortal since it will always move.

—William Faulkner (1897–1962)
“Who makes the fairest show means most deceit.”
—William Shakespeare (1564–1616)
