Famous quotes containing the word motions:
“Progress celebrates Pyrrhic victories over nature. Progress makes purses out of human skin. When people were traveling in mail coaches, the world got ahead better than it does now that salesmen fly through the air. What good is speed if the brain has oozed out on the way? How will the heirs of this age be taught the most basic motions that are necessary to activate the most complicated machines? Nature can rely on progress; it will avenge it for the outrage it has perpetrated on it.”
—Karl Kraus (1874–1936)
“How often our involuntary facial motions testify to the thoughts we were keeping secret, and betray us to those around!”
—Michel de Montaigne (1533–1592)
“A funeral is not death, any more than baptism is birth or marriage union. All three are the clumsy devices, coming now too late, now too early, by which Society would register the quick motions of man.”
—E.M. (Edward Morgan)
