Famous quotes containing the words table, energy, storage and/or traits:

    How to attain sufficient clarity of thought to meet the terrifying issues now facing us, before it is too late, is ... important. Of one thing I feel reasonably sure: we can’t stop to discuss whether the table has or hasn’t legs when the house is burning down over our heads. Nor do the classics per se seem to furnish the kind of education which fits people to cope with a fast-changing civilization.
    Mary Barnett Gilson (1877–?)

    In the west, Apollo and Dionysus strive for victory. Apollo makes the boundary lines that are civilization but that lead to convention, constraint, oppression. Dionysus is energy unbound, mad, callous, destructive, wasteful. Apollo is law, history, tradition, the dignity and safety of custom and form. Dionysus is the new, exhilarating but rude, sweeping all away to begin again. Apollo is a tyrant, Dionysus is a vandal.
    Camille Paglia (b. 1947)

    Many of our houses, both public and private, with their almost innumerable apartments, their huge halls and their cellars for the storage of wines and other munitions of peace, appear to me extravagantly large for their inhabitants. They are so vast and magnificent that the latter seem to be only vermin which infest them.
    Henry David Thoreau (1817–1862)

    In the years of the Roman Republic, before the Christian era, Roman education was meant to produce those character traits that would make the ideal family man. Children were taught primarily to be good to their families. To revere gods, one’s parents, and the laws of the state were the primary lessons for Roman boys. Cicero described the goal of their child rearing as “self- control, combined with dutiful affection to parents, and kindliness to kindred.”
    C. John Sommerville (20th century)
