Equivalence Class Structure

Famous quotes containing the words class and/or structure:

    “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)

    “One theme links together these new proposals for family policy—the idea that the family is exceedingly durable. Changes in structure and function and individual roles are not to be confused with the collapse of the family. Families remain more important in the lives of children than other institutions. Family ties are stronger and more vital than many of us imagine in the perennial atmosphere of crisis surrounding the subject.”
    —Joseph Featherstone (20th century)
