Famous quotes containing the words similar and/or proposals:
“... the truth is hidden from us. Even if a mere piece of luck brings us straight to it, we shall have no grounded conviction of our success; there are so many similar objects, all claiming to be the real thing.”
—Lucian (c. 120–c. 180)
“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)
