Famous quotes containing the words variations and/or age:
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
“Not in vain is Ireland pouring itself all over the earth. Divine Providence has a mission for her children to fulfill; though a mission unrecognized by political economists. There is ever a moral balance preserved in the universe, like the vibrations of the pendulum. The Irish, with their glowing hearts and reverent credulity, are needed in this cold age of intellect and skepticism.”
—Lydia M. Child (1802–1880)
