Famous quotes containing the words oil and/or parity:
“Can he who has discovered only some of the values of whalebone and whale oil be said to have discovered the true use of the whale?”
—Henry David Thoreau (1817–1862)
“The U.S. is becoming an increasingly fatherless society. A generation ago, an American child could reasonably expect to grow up with his or her father. Today an American child can reasonably expect not to. Fatherlessness is now approaching a rough parity with fatherhood as a defining feature of American childhood.”
—David Blankenhorn (20th century)
