Famous quotes containing the word symbols:
“Many older wealthy families have learned to instill a sense of public service in their offspring. But newly affluent middle-class parents have not acquired this skill. We are using our children as symbols of leisure-class standing without building in safeguards against an overweening sense of entitlement—a sense of entitlement that may incline some young people more toward the good life than toward the hard work that, for most of us, makes the good life possible.”
—David Elkind (20th century)
“If the Americans, in addition to the eagle and the Stars and Stripes and the more unofficial symbols of bison, moose and Indian, should ever need another emblem, one which is friendly and pleasant, then I think they should choose the grapefruit. Or rather the half grapefruit, for this fruit only comes in halves, I believe. Practically speaking, it is always yellow, always just as fresh and well served. And it always comes at the same, still hopeful hour of the morning.”
—Johan Huizinga (1872–1945)
