Copper Age

Famous quotes containing the words copper and/or age:

    “He had put, within his reach,
    A box of counters and a red-veined stone,
    A piece of glass abraded by the beach,
    And six or seven shells,
    A bottle with bluebells,
    And two French copper coins, ranged there with careful art,”
    —Coventry Kersey Dighton Patmore (1823–1896)

    “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)
