Famous quotes containing the words primary, secondary and/or structure:
“One of the effects of a safe and civilised life is an immense oversensitiveness which makes all the primary emotions somewhat disgusting. Generosity is as painful as meanness, gratitude as hateful as ingratitude.”
—George Orwell (19031950)
“Cloud-clown, blue painter, sun as horn,
Hill-scholar, man that never is,
The bad-bespoken lacker,
Ancestor of Narcissus, prince
Of the secondary men. There are no rocks
And stones, only this imager.”
—Wallace Stevens (18791955)
“One theme links together these new proposals for family policythe 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)
