Famous quotes containing the words formula and/or class:
“In the most desirable conditions, the child learns to manage anxiety by being exposed to just the right amounts of it, not much more and not much less. This optimal amount of anxiety varies with the child’s age and temperament. It may also vary with cultural values.... There is no mathematical formula for calculating exact amounts of optimal anxiety. This is why child rearing is an art and not a science.”
—Alicia F. Lieberman (20th century)
“There is a struggle between the Oriental and the Occidental in every nation; some who would be forever contemplating the sun, and some who are hastening toward the sunset. The former class says to the latter, When you have reached the sunset, you will be no nearer to the sun. To which the latter replies, But we so prolong the day.”
—Henry David Thoreau (1817–1862)
