Famous quotes containing the words foreign, signals and/or intelligence:
“Friends, both the imaginary ones you build for yourself out of phrases taken from a living writer, or real ones from college, and relatives, despite all the waste of ceremony and fakery and the fact that out of an hour of conversation you may have only five minutes in which the old entente reappears, are the only real means for foreign ideas to enter your brain.”
—Nicholson Baker (b. 1957)
“The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.”
—Lawrence Kutner (20th century)
“Most women’s intelligence tends more to the improving of their folly than their reason.”
—François, Duc De La Rochefoucauld (1613–1680)
